Características físico-químicas, sensoriais e perfil de ácidos graxos do leite de cabras saanen alimentadas com cactáceas

The objective of this research was to evaluate the influence of the supply of five types of native and exotic cacti Brazilian semiarid northeast on the sensory characteristics of milk of Saanen goats. Five multiparous goats were used with nine weeks of lactation, average live weight of 50 kg ± 4 kg., confined and distributed in a Latin square design 5 x 5 with five experimental diets and five periods. Each period lasted 17 days, with 10 days of adaptation to the diets of the animals and seven days for the data collection. The treatments were defined based on dry matter consisted of: 47.33 to 50.12% of a cactus (“Xiquexique”, “Mandacaru”, “Facheiro” or two species of forage cactus “Miúda” or “Orelha de Elefante Mexicana”) more 18.78 to 19.79% hay of plant “Sabiá” and 31.10 to 32.89% of concentrate. There was not effect of the experimental diets in the physical and chemical composition of milk for fat, total solids and salts, which showed mean values of 3.24%; 11.30% and 0.66%, respectively. However the protein, lactose, nonfat dry extract and freezing point were affected by diets. In the profile of fatty acids was higher concentration of fatty short and medium chain fatty acids, however, there were not changes between treatments, except for the butyric acid (C4:0), with mean values of 4.24% (“Orelha de Elefante Mexicana”) to 6.05% (“Facheiro”). The diets also did not provide sensory changes in milk for the parameters: odor, flavor, aftertaste and overall assessment. The use of the five cactus in the diet of dairy goats do not influence the sensory characteristics and lipid profile of milk. The physical and chemical composition of milk was showed within the minimum requirements of current legislation, except for nonfat dry extract and freezing point.

Avaliação da suplementação de vitamina E sobre a concentração de alfa-tocoferol no leite materno em mulheres com partos prematuros

The term vitamin E refers to a group of eight molecular compounds which differ in structure and bioavailability, and the RRR-alpha-tocopherol more biologically active form. The composition of vitamin E in breast milk undergoes variations during lactation, colostrum and milk richer in this micronutrient compared to transitional and mature milk. Newborns, especially premature infants are more susceptible to vitamin E deficiency and to prevent the damage caused by this deficiency has been proposed supplementation of neonates with this micronutrient, however, there is no consensus to carry out this intervention. Thus, maternal supplementation with RRRalpha-tocopherol in the postpartum period can be a good alternative to try to raise the alpha-tocopherol levels in breast milk and therefore provide the premature newborn adequate amounts of vitamin E. This study to evaluate the effect of supplementation with 400 UI acetate RRR-alpha-tocopherol in women with premature births, on the concentration of alpha-tocopherol in breast milk colostrum, transitional and mature. The study included 89 healthy adult women were enrolled in the control group (n = 51) and supplemented group (n = 38). Blood samples were collected and milk colostrum soon after birth (0h milk) twenty-four hours, new rate of colostrum milk was collected (24h milk). The transitional and mature milk were collected in seven days (7d milk) and thirty days (30d milk) after delivery, respectively. Supplementation in the supplemented group was held after the collection of blood and 0h milk. The alpha-tocopherol analyzes were performed by high-performance liquid chromatography. Serum levels of alpha-tocopherol less than 516 μg/dL were considered indicative of nutritional deficiency. The average concentration of alphatocopherol in the serum of the control group mothers was 1159.8 ± 292.4 μg/dL and the supplemented group was 1128.3 ± 407.2 μg/dL (p = 0.281). All women had nutritional status in vitamin E suitable. In both groups, it was observed that the concentration of vitamin E in colostrum milk was higher compared to transitional and mature milk. In the supplemented group, the concentration of alpha-tocopherol in the milk increased 60 % after supplementation, from 1339.3 ± 414.2 μg/dL (0h milk) to 2234.7 ± 997.3 μg/dL (24h milk). While the control group values in colostrum 0h and colostrum 24h were similar (p = 0.681). In the control group the follow-on milk alphatocopherol value was 875.3 ± 292.4 μg/dL and in the group supplemented 1352.8 ± 542.3 μg/dL, an increase of 35% in the supplemented group compared to control (p <0.001). In mature milk alpha-tocopherol concentrations between the control group (426.6 ± 187.5 μg/dL) and supplemented (416.4 ± 214.2 μg/dL) were similar (p = 0.853). Only 24h milk supplemented group answered the nutritional requirement of alpha-tocopherol (4 mg/day) of the newborn. These results show that the transport of this micronutrient for milk occurs in a controlled and limited way. Thus, the native vitamin E supplementation increases the concentration of alpha-tocopherol in colostrum and milk and transition does not influence the concentration in mature milk. Only the increase in colostrum milk was sufficient to meet the nutritional requirement of premature newborns.

Ocorrência de leite instável na região semiárida do Rio Grande do Norte e sua correlação com a qualidade do leite

The unstable non acid milk (UNAM) is characterized by coagulation in the alcohol test and wanted acidity (14-18°D). Among Brazilian regions, the South and Southeast have the highest occurrence of LINA, which has been causing problems for both producers and for industries, due to the disposal or undervaluation of milk. In the Northeast there are few studies that indicate their occurrence and quality. The objective of this study was to identify the occurrence of unstable non-acid milk in the west and central mesoregions of Rio Grande do Norte, determine their physicochemical characteristics, test alcoholic graduations and evaluate their correlation with the quality of milk. 176 raw milk samples were analyzed in the period from September to December /2014 from 23 APASA’s cooling tanks, located in 7 cities of west and central mesoregions RN. The samples were collected in duplicate, one sample used for alcohol testing at 68, 72 and 76%, measurement of pH, acidity, electrical conductivity and boiling proof, made in LABOLEITE / UFRN; and the other sample containing Bronopol® preservative, was sent to the APCBRH (Cattle Breeders Association Paranaense Holstein) laboratory in Curitiba-PR, which were analyzed fat, protein, total solids, lactose, casein, urea nitrogen and somatic cell count. The test alcohol samples disapproved 31.82%, of which 30% proved to be non-acid, and 30% had high acidity. The samples were divided into three classes: Stable Milk, UNAM and acid milk. 3% Tukey test was used for comparison of stable milk components and UNAM and there was no significant difference between them. Both classes obtained averages within the standard required by IN 62. The average value of electric conductivity was 4.84 mS/cm for stable milk, 4.55 mS/cm for unstable and acid milk and 4.53 mS/cm for non-acid unstable milk. The electrical conductivity was positively correlated with alcohol stability of milk and negative correlation with acidity and pH. Could not observe direct relationship between the electrical conductivity and the somatic cell count.The boiling test was negative for all samples UNAM. It can be concluded that the incidence of UNAM in the studied region is low, although the predisposing factors such as heat stress, drought and nutritional deficiency. In conclusion, the UNAM has quality similar to stable milk, conform the norms required by Agriculture Ministry, and with adequate thermal stability, which proves that there is no reason to reject this milk by industry.

This study aimed to evaluate the effect of diet with selenium on the physico-chemical composition and somatic cell count of buffalo milk, and check the selenium waste in milk and minas kind fresh cheese. For the analysis of physical-chemical composition and SCC were used 2264 buffalo milk data from the Murrah, belonging to Tapuio Ltda, located in the agreste region of the state of Rio Grande do Norte, in the period 2010 to 2014. To check the amount of selenium residue in buffalo milk and fresh cheese mines were used 100 Murrah buffaloes divided into 5 lots. The batches were formed according to the production levels of animals, wherein the amount of concentrate fed varied within each lot, which received 0.08 ppm / Se / kg of concentrate. Was collected from 300 ml of tank milk from and each lot, as well as 300 gr minas cheese, from August to November 2014, with the collection of lots held only in the month of November. The samples were sent to the Pernambuco Tecnology Institute for selenium residue analysis. The effect of the seasons was contrasted in two ways, namely: Spring, Summer, Autumn and Winter season or drought and rainy season. The analyzes statistics were performed using the procedures available in the software SAS® (SAS, 2002). Selenium level provided to the animals in this study was not significant to the point of detection of their residue in milk and the cheeses. However, it influences the reduction of the CCS. The milk characteristics were not affected by selenium use only the seasons.

Desenvolvimento de métodos para quantificação de benzilpenicilina em medicamentos veterinários e seus resíduos em leite bovino e caprino por UFLC-DAD

The Benzylpenicillin (PENG) have been as the active ingredient in veterinary medicinal products, to increase productivity, due to its therapeutic properties. However, one of unfortunate quality and used indiscriminately, resulting in residues in foods exposed to human consumption, especially in milk that is essential to the diet of children and the ageing. Thus, it is indispensable to develop new methods able to detect this waste food, at levels that are toxic to human health, in order to contribute to the food security of consumers and collaborate with regulatory agencies in an efficient inspection. In this work, were developed methods for the quality control of veterinary drugs based on Benzylpenicillin (PENG) that are used in livestock production. Additionally, were validated methodologies for identifying and quantifying the antibiotic residues in milk bovine and caprine. For this, the analytical control was performed two steps. At first, the groups of samples of medicinal products I, II, III, IV and V, individually, were characterized by medium infrared spectroscopy (4000 – 600 cm-1). Besides, 37 samples, distributed in these groups, were analyzed by spectroscopy in the ultraviolet and near infrared region (UV VIS NIR) and Ultra Fast Liquid Chromatograph coupled to linear arrangement photodiodes (UFLC-DAD). The results of the characterization indicated similarities, between PENG and reference standard samples, primarily in regions of 1818 to 1724 cm-1 of ν C=O that shows primary amides features of PENG. The method by UFLC-DAD presented R on 0.9991. LOD of 7.384 × 10-4 μg mL-1. LOQ of 2.049 × 10-3 μg mL-1. The analysis shows that 62.16% the samples presented purity ≥ 81.21%. The method by spectroscopy in the UV VIS NIR presented medium error ≤ 8 – 12% between the reference and experimental criteria, indicating is a secure choice for rapid determination of PENG. In the second stage, was acquiring a method for the extraction and isolation of PENG by the addition of buffer McIlvaine, used for precipitation of proteins total, at pH 4.0. The results showed excellent recovery values PENG, being close to 92.05% of samples of bovine milk (method 1). While samples of milk goats (method 2) the recovery of PENG were 95.83%. The methods for UFLC-DAD have been validated in accordance with the maximum residue limit (LMR) of 4 μg Kg-1 standardized by CAC/GL16. Validation of the method 1 indicated R by 0.9975. LOD of 7.246 × 10-4 μg mL-1. LOQ de 2.196 × 10-3 μg mL-1. The application of the method 1 showed that 12% the samples presented concentration of residues of PENG > LMR. The method 2 indicated R by 0.9995. LOD 8.251 × 10-4 μg mL-1. LOQ de 2.5270 × 10-3 μg mL-1. The application of the method showed that 15% of the samples were above the tolerable. The comparative analysis between the methods pointed better validation for LCP samples, because the reduction of the matrix effect, on this account the tcalculs < ttable, caused by the increase of recovery of the PENG. In this mode, all the operations developed to deliver simplicity, speed, selectivity, reduced analysis time and reagent use and toxic solvents, particularly if compared to the established methodologies.

Influência da alimentação sobre os níveis de retinol no leite caprino

The caprine milk is a product of high biological value and high digestibility. Due to these characteristics it is quite used by newly born children that are not breastfed or that are intolerant to the bovine milk. The vitamin deficiency is a public health problem in underdeveloped areas as the Northeast of Brazil and where areas the caprine ones adapt very well. The present study was led to analyze the influence of the feeding in the vitamin levels in the caprine milk. The animals used were the races Saanen and Murciana, divided in three groups. The first group with 38 animals of race Saanen and the second with 30 animals of race Murciana were, fed with concentrated and voluminous. A third group with 20 animals of the race Saanen was fed exclusively with voluminous. The four group was added with 10. 000 UI of retinol palmitato, administered directly, like capsule, in the mouth of animal. Parallel it was verified the level of retinol of milk in the beginning and final of the sucked, in the goats of the second group (race Murciana n =30). The retinol of caprine milk was determined through the system of liquid cromatografia of high efficiency (HPLC). The retinol levels in the studied groups were respectively: first (38. 5 ± 12. 7 μg/100ml), second (40. 5 ± 9. 7 μg/100ml); third, with 20 animals of race Saanen fed exclusively with voluminous (23. 1 ± 6. 7 μg/100ml) and in the group a, suplementation with 10. 000 UI of retinol palmitato (43,7 ± 18,8 μg/100ml) before, and (61,9 ± 26,9 μg/100ml) after the supplementation. It was not found significant difference between the averages from animals of the first and second group, that were fed with the same concentrate diet and voluminous, showing that the retinol levels in the milk of these two races are equivalent. Already in the animals of the first and third group that they were fed with different diets, in those which diet was just voluminous, a drastic reduction was verified in the retinol levels. In relation to the retinol of the milk in different moments from the same sucked, it was observed in the beginning of the breast-feeding (22. 6 ± 9. 8 μg/100ml) and at the end of the sucked (49. 6 ± 14. 7μg/100ml), being the difference between the averages, statistically significant (p < 0,0001). Already in the animals that were supplemented, a significant increase was observed in the retinol concentration, being obtained a medium response of 41,85%

Avaliação de megadoses de retinol palmitato no pós-parto imediato sobre o retinol do leite de puérperas atendidas no Hospital José Pedro Bezerra, Natal-RN

Vitamin A deficiency (VAD) is a serious public health problem in developing countries, and as a therapeutic and prophylactic measure retinil palmitate is being supplemented. Nevertheless its efficacy has been questioned. The objective of the study was to evaluate the supplementation of two retinil palmitate megadosis on the serum retinol levels of post partum healthy mothers from Dr. José Pedro Bezerra (Hospital Santa Catarina) hospital, Natal - RN. The enrolled women (n=199) were randomly distributed into three studied groups and supplemented with retinil palmitate immediately after delivery with a single 200,000 IU dose (group S1), two 200,000 IU dose (group S2) with 24h difference between the doses, or no supplementation (group C). Among women selected, 143 remained until the end of the study. The influence of vitamin A dietary intake was evaluated during pregnancy and after 30 days of delivery. The average intake of the population was reasonable, but a high prevalence of inadequate intake was found. Retinol in colostrums and mature milk was determined by high performance liquid chromatography (HPLC). The retinol average in colostrums and mature milk in the supplemented and control groups were adequate according to the reference values. In colostrums, women from groups C, S1 and S2 presented retinol averages by milk volume of 94.8 ± 40.2 µg/dL, 92.2 ± 50.0 µg/dL and 91.8 ± 53.7 µg/dL, respectively. No difference was found between these averages (p=0.965), this was also seen when the values where expressed as µg/g of fat (p=0.905). After 30 days of delivery, retinol per milk volume differed between the control group (36.6 ± 17.5 µg/dL) and groups supplemented with 200,000 IU (51.0 ± 28.8 µg/dL) or 400,000 IU (55.2 ± 31.6 µg/dL) of retinil palmitate (p<0,05). Nevertheless, when S1 and S2 groups where compared, no significant difference was found (p=0.97). Considering retinol/g of fat, the means were 12.7 ± 6.7 µg/g, 15.6 ± 8.3 µg/g and 17.2 ± 8.9 µg/g for groups C, S1 and S2, respectively, with significant difference between groups S2 and C (p=0,01). Subclinical VAD prevalence showed a serious public health problem in the study population (32% in colostrums and 31.5% in mature milk). When analyzing the groups separately, the group which received two doses (200,000 IU + 200,000 IU) presented the lowest VAD prevalence (20.7%). Retinil palmitate supplementations of 200,000 IU and 400,000 IU (divided in two doses) in the immediate post partum showed no significant difference. Nevertheless, the 400,000 IU (divided in two doses) supplementation showed a reduction in VAD

Nutrição e fertilidade em bovinos de leite

Neste relatório são descritas as atividades desenvolvidas durante o estágio curricular em nutrição e fertilidade de bovinos de leite. Engloba também, uma revisão bibliográfica sobre a influência da nutrição na fertilidade e na produção de leite, e um estudo em que se procurou avaliar a influência do controlo da ingestão de água numa vacaria de leite. Para isso, foram utilizados 2 sistemas de produção (sistemas semi-extensivo e intensivo) e maneio alimentar. Independentemente do sistema, observou-se uma estreita relação da ingestão de água com ingestão de matéria seca, e produção de leite (ingerindo 5kg de água por cada kg de matéria seca ingerida por dia e apresentando uma produção de leite cerca de 29% da quantidade de água ingerida). Em ambos os sistemas, o controlo da ingestão de água é um potencial indicador de estro, pois existe uma diminuição significativa da ingestão de água nesse período; Abstract: This report describes the activities carried out during the internship in nutrition and fertility in dairy cattle. It also includes a literature review about the influence of nutrition on the fertility and milk production. It provides a case study that sought to assess the influence of the water intake control in a dairy farm. For this, we used 2 different production systems (semi-extensive and intensive systems) and ration. Regardless of the production or feeding system, there was a close relationship of water intake, dry matter intake and milk production (ingesting 5 kg of water per kg of dry matter, and producing nearly 29% of the total water intake). Both groups showed a decrease in water intake related to oestrus, so it means that it could be a potential indicator of oestrus behaviour and be helpful for the detection of the metabolic disorders.

Mastite: importância do maneio, ambiente e animal. Plano de prevenção, controlo e impacto na quantidade e qualidade do leite

No presente relatório são caracterizadas e descritas as atividades desenvolvidas durante o estágio curricular na vertente da importância do maneio, ambiente e animal no controlo das mastites. Contempla ainda uma revisão bibliográfica e estudo de caso sobre a problemática das mastites na exploração. No estudo de caso procurou avaliar-se a influência do maneio, ambiente e animal no controlo das mastites e o impacto que estas representam na quantidade e na qualidade do leite. Foi ainda realizado estudo em 30 bovinos, identificados como animais problema, com recolha de amostras de leite para análise de antibiograma com deteção de agente. Foi implementado um plano de prevenção e controlo de mastites que consistiu na implementação de medidas de higiene e maneio dos animais, implementação de operações de rotinas de ordenha, implementação de medidas preventivas com recurso a vacinação e estabelecimentos de protocolos de tratamentos para os animais com patologias associadas às mastites. Os resultados obtidos foram muito positivos, diminuindo de forma drástica a incidência de mastites de 20% para 5% anual e consequentemente, uma melhoria considerável da quantidade de leite (22 para 33 L/vaca/dia) e na qualidade do leite (CCS <300 000 cel/mL) produzido; Abstract: Mastitis: Importance of management, environment and animal. Plan for the prevention, control and impact on the quantity and quality of milk This report characterize and describe the activities carried out during the traineeship in the aspect of the importance of management, environment and animal in the control of mastitis. There is also a literature and a case study on the problem of mastitis on the farm review. In the case study we sought to evaluate the influence of management, environment and animal in the control of mastitis and the impact that they represent in the quantity and quality of milk. A study was also carried out in 30 cattle, identified as problem animals, with milk samples for antibiotic susceptibility analysis with agent detection. It was implemented a mastitis prevention and control plan with the implementation of hygiene measures and husbandry of animals, implementation of milking routine operations, and implementing preventive measures using vaccination and treatment protocols establishment for animal diseases associated with mastitis. The results were very positive, decreasing dramatically the incidence of 20% mastitis to 5% per year and hence a considerable improvement of the quantity (22 to 33 L/cow/day) and quality ( SCC <300,000 cells/mL) of milk produced.

Aspectos estruturais, farmacológicos e biológicos de fucanas da alga marrom sargassum vulgare

The present study examines the chemical composition and their effects on free radicals, inflammation, angiogenesis, coagulation, VEGF effects and cellular proliferation of a polysaccharides from alga Sargassum vulgare. The sulfated polysaccharide was extracted from brown seaweed by proteolysis with enzymes maxataze. The presence of proteins and sugars were observed in crude polysaccharides. Fractionation of this crude extract was made with growing concentration of acetone (0.3-1.5 v) and produced four groups of polysaccharides. Anionic polysaccharides from brown seaweed Sargassum vulgare, SV1and PSV1 were fractionated (SV1) and purified (PSV1), and displayed with high total sugars and sulfate content and very low level of protein. This fucan SV1 contains low levels of protein and high carbohydrate and sulfate content. This polysaccharides prolonged activated partial thromboplastin time (aPTT) at 50 μg (>240 s). SV1 was found to have no effect on prothrombin time (PT), corresponding to the extrinsic pathway of coagulation. SV1 exhibits high antithrombotic action in vivo, with a concentration ten times higher than heparin. Polysaccharides from S. vulgare promoted direct inhibition enzymatic activity of thrombin and stimulated enzymatic activity of FXa. SV1 showed optimal inhibitory activity of thrombin (50.2±0.28%) at a concentration of 25 μg/mL. Its antioxidant action on scavenging radicals by DPPH was (22%), indicating the polymer has no cytotoxic action (hemolytic) on ABO and Rh blood types in different erythrocyte groups and displays strong anti-inflammatory action on all concentrations tested in the carrageenan-induced paw edema model, demonstrated by reduced edema and cellular infiltration. Angiogenesis is a dynamic process of proliferation and differentiation. It requires endothelial proliferation, migration, and tube formation. In this context, endothelial cells are a preferred target for several studies and therapies. The antiangiogenic efficacy of polysaccharides was examined in vivo in the chick chorioallantoic membrane (CAM) model by using fertilized eggs. Decreases in the density of the capillaries were assessed and scored. The results showed that SV1 and PSV1 have an inhibitory effect on angiogenesis. These results were also confirmed by inhibition tubulogenesis in rabbit aorta endothelial cell (RAEC) in matrigel. These compounds were assessed in Apoptosis assay (Annexin V - FITC / PI) and cell viability by MTT assay of RAEC. These polysaccharides do not affect the viability and do not have apoptotic or necrotic action. RAEC cell when incubated with SV1 and PSV1showed inhibition of VEGF secretion, observed when compounds were incubated at 25, 50 and 100 μg/μL. The VEGF secretion with the RAEC cell line for 24 h, was more effective for PSV1 at 50 μg/μL(71.4%) than SV1 100 μg/μL (75.9%). SV1 and PSV1 had an antiproliferative action (47%) against tumor cell line HeLa. Our results indicate that these sulfated polysaccharides have antiangiogenic and antitumoral actions
