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%

Marine radiocarbon resservoir effect of coastal waters off Cape Verde Archipelago

Quantification of the marine radiocarbon reservoir effect (R) is essential in order to calibrate conventional 14C dates from marine shell samples with reliability. R also provides information concerning the intensity of coastal upwelling in marine regions influenced by this phenomenon. 14C ages of closely associated marine samples (mollusk shells) and terrestrial samples (goat bones) from São Vicente Island, Cape Verde Archipelago, permitted the first calculation of the marine 14C reservoir effect in this region. A R weighted mean value of 70 ± 70 14C yr was obtained. This value is in accordance with the previously published oceanographic conditions of the region indicating the existence of a seasonal active upwelling regime.

CLIMATE CHANGE ADAPTATION IN VULNERABLE CROP AND LIVESTOCK PRODUCTION SYSTEMS IN MGETA, TANZANIA

Increased occurrence of drought and dry spells during the growing season have resulted in increased interest in protection of tropical water catchment areas. In Mgeta, a water catchment area in the Uluguru Mountains in Tanzania, water used for vegetable and fruit production is provided through canals from the Uluguru South Forest Reserve. The clearing of forest land for cultivation in the steep slopes in the area is causing severe land degradation, which is threatening the water catchment area, livelihoods, and food security of the local communities, as well as the major population centers in the lowlands. In this paper, the economic performance of a traditional cropping-livestock system with East African (EA)-goats and pigs and extensive vegetable production is compared with a more sustainable and environmentally friendly crop-dairy goat production system. A linear programming (LP) crop-livestock model, maximizing farm income considering the environmental constraints in the area was applied for studying the economic performance of dairy goats in the production system. The model was worked out for the rainy and dry seasons and the analysis was conducted for a basic scenario representing the current situation, based on the variability in the 30 years period from 1982-2012, and in a scenario of both lower crop yields and increased crop variability due to climate change. Data obtained from a sample of 60 farmers that were interviewed using a questionnaire was used to develop and parameterize the model. The study found that in the steep slopes of the area, a crop-dairy goat system with extensive use of grass and multipurpose trees (MPTs) would do better than the traditional vegetable gardening with the EA goat production system. The crop-dairy goat system was superior both in the basic and in a climate change scenario since the yield variation of the grass and MPTs system was less affected compared to vegetable crops due to more tree cover and the use of perennial grasses. However, the goat milk production in the area was constrained by inadequate feeding and lack of an appropriate breeding program. Hence, farmers should enhance goat milk production by supplementing with more concentrate feed and by implementing goat-breeding principles. Moreover, policy measures to promote such a development are briefly discussed.

Galanin interacts with Neuropeptide Y Y1 receptor in the dentate gyrus of the hippocampus through GALR2/NPYY1R heterodimers

We have shown Galanin(GAL) and Neuropeptide Y Y1(NPYY1) interactions at behavioural, cellular and receptor levels through GALR2/NPYY1R heterodimers in the amygdala. The aim of this work was to analyze GAL/NPYY1R interactions in the Dentate Gyrus(DG) of the Hippocampus, using autoradiographic, in situ hybridization and in situ proximity ligation assay(PLA). Rats(n=6) were sacrificed 15 minutes or 5 hours after icv injections of GAL(3nmol) and DG sections were incubated with NPYY1R agonist [I125]-[Leu31,Pro34]PYY(25 pM) or NPYY1R-33PdATP specific probe, for autoradiography and in situ hybridization respectively. Autoradiograms were analyzed using NIH image analysis system and Student’s unpaired t-test was used. For PLA, DG sections were incubated with anti-GALR2 Rabbit(1:100) and anti-NPYY1R Goat(1:200). PLA signals were detected with PLA PLUS or MINUS probes for rabbit or goat/mouse antibodies. PLA signals were visualized by using a confocal microscope Leica TCS-SL confocal microscope(Leica). We observed that GAL significant increased the NPYY1R agonist [I125]-[Leu31,Pro34]PYY binding in the DG by 20% (p<0,05) and the NPYY1R mRNA expression in the granular layer of DG by 31% (p<0,001). Moreover, PLA-positive red clusters were found specifically in the polymorphic layer and subgranular zone of the DG. No PLA clusters were observed neither in the molecular layer of the DG nor in the corpus callosum, an area that seems to lack of GALR2 receptor. These results demonstrate a novel mechanism of interaction between GAL and NPY1R in the DG at receptor level, probably involving the formation of GALR2/NPYY1R heteroreceptor complexes.

A qualidade higiênico-sanitária do leite de cabra, além de ser uma característica indispensável ao produto, exigida pela legislação Brasileira, contribui para diminuição nas perdas econômicas decorrentes da mastite e para a manutenção dos produtores na atividade. O Kit Embrapa de Ordenha Manual® para caprinos leiteiros é um conjunto de utensílios e práticas indispensáveis para a obtenção higiênica do leite de cabra, o qual apresenta-se como uma alternativa viável aos agricultores familiares devido à sua facilidade na utilização e baixo custo de aquisição. O Kit foi implantado e validado em 41 propriedades familiares, localizadas nos estados do Rio Grande do Norte, Paraíba e Ceará. Procedeu-se a coleta de leite de cabra 3 dias antes e 3 dias após a utilização do Kit, para a realização da Contagem Total de Bactérias (CTB). Observou-se uma redução média de 72% da CTB no leite produzido, e, 95% das propriedades adequaram-se à CTB exigida pela legislação Brasileira. [Effect of the use of the Milking Manual® EMBRAPA Kit for dairy goats total count in milk bacteria]. Abstract: The goat milk production in Brazil stands out in the Northeast, where the breeding conditions and government programs favor the production. The sanitary hygienic quality of goat milk as well as being an indispensable feature to the product, required by Brazilian law, contributes to decrease in economic losses resulting from mastitis and to the maintenance of the producers in the activity. The Embrapa manual milking kit® for dairy goats is an essential set of tools and practices for obtaining hygienic goat milk, which presents itself as a viable alternative to farmers due to its ease of use and low cost. The Kit has been deployed and validated in 41 family farms in the states of Rio Grande do Norte, Paraíba and Ceará. The goat milking practice was carried out both three days before and three days after using the kit for the realization of Total Bacteria Count (CTB). There was an average reduction of 72 % CTB on the milk, and 95 % of the properties have adapted to the CTB required by Brazilian law.

Alternativas atuais e potenciais de suplementação alimentar de caprinos no semi-árido do Nordeste.

A caprinocultura na reglao semi-árida do Nordeste se caracteriza pela extensividade e por baixos níveis de produtividade decorrentes, principalmente, da acentuada variação estacional na oferta de forragem da caatinga, a qual constitui sua base alimentar. Existe um consenso quanto a necessidade de suplementar os animais nos períodos críticos, tanto com energia como com proteína. As alternativas atualmente disponíveis, como a palma forrageira (Opuntia ficus indica Mill), os restolhos de cultura, e o capim buffel (Cenchrus ciliaris) sao volumosos de reduzido valor energético e são mais utilizados dentro de um enfoque de sobrevivência dos animais. Os suplementos de maior valor nutritivo são de uso limitado e apresentam problemas de economicidade. As perspectivas de uso da ureia, da leucena (Leucaena leucocephala (Lam.) de Wit) e do guandu (Cajanus cajan (L.) Millsp) na suplementaçao de caprinos no semi-árido, são discutidas com base no seu potencial como fontes de nutrientes e como alternativas adaptáveis às condições agro-ecológicas e sócio-econômicas da região.

Usefulness of clinical observations and blood chemistry values for predicting clinical outcomes in dairy goats with pregnancy toxaemia

Background Pregnancy toxaemia (PT) is a disease that affects pregnant goats during their last month of gestation and is characterized by a high case fatality rate. This study involved 32 does maintained on a commercial dairy goat farm that were diagnosed with PT. A physical examination was performed on and haematology parameters obtained from each doe, at the time of diagnosis. The data from the 24 PT goats that died was compared with the corresponding data from the 8 PT goats that survived. Results Polypnea, swollen limbs, anorexia with absence of ruminal motility, recumbency, nervous signs and drooping ears were the most frequently observed clinical manifestations. Nineteen out of 21 recumbent goats died. Sixteen out of 17 goats with anorexia and absence of ruminal motility died. Mean beta-hydroxybutyric acid (BHBA) values in the goats that died were not significantly different from those in goats that survived. The blood values for pH and pCO2 (p < 0.005) as well as for HCO3 −, BE and K+ (p < 0.001) were significantly lower in the goats that died than in those that survived. Conclusions The clinical signs most indicative of a poor prognosis are anorexia with absence of ruminal motility and recumbency. Among the blood parameters to be considered, hypokalaemia and metabolic acidosis are the most relevant. Goats with PT have a high mortality and their condition can deteriorate very fast. Based on the authors’s experience, a good strategy to minimize the economic losses caused by PT is to focus on the offspring survival rate since an early decision (induction of kidding or caesarian surgery) can increase the number of alive kids.

Performance and ruminal morphologic characteristics of Saanen kids fed ground, pelleted or extruded total ration

The aim of the present study was to determine feed intake and average weight gain and to evaluate the ruminal morphologic characteristics of Saanen kids slaughtered at 30, 45 and 60 days of age, according to a completely randomized design. Thirty-six non-castrated male Saanen kids were fed ground total ration, pelleted total ration, or extruded total ration. Feed intake and refusals were controlled daily and the animals were weighed at birth and then once a week. Newborn kids received a milk replacer and were weaned at 45 days. Immediately after slaughter, the animals were eviscerated, the entire digestive apparatus was removed from the carcass. The reticulo-rumen was separated, emptied, washed and weighed. Samples were collected from the dorsal sac, pillar area and ventral sac of the rumen, fixed for about 24h in Bouin's solution, dehydrated, embedded in Histosec and cut into 5 mu m sections. Results showed that dry matter intake (DMI) at weaning and post-weaning and weight gain were higher (P < 0.05) in animals that received the pelleted total ration. The weight of the reticulo-rumen accompanied body development and was heavier in these animals. Histologically, after weaning ruminal papillae were more developed in animals that received pelleted total ration. Length of papillae increased with increase of age. The ratio of papillary height to papillary width increased with age in the ventral sac and until weaning (P > 0.05). We conclude that the pelleting process of the total ration favored increased intake, with a 46.7% increase in weight gain and increase in rumen weight and papillae length, suggesting that best results are obtained with this processing. In general, no difference was observed between the results obtained with extruded and ground total ration, although animals fed extruded total ration showed an increase in rumen weight and papillae width.

Sorological evaluation of commercial vaccines against enterotoxemia in goats.

Enterotoxemia in sheep and in goats is caused by the effects of the epsilon toxin of C/ostridium perfringens type D, being considered the main infectious cause of mortality in those animal species. The main prophylactic measures include adequate nutritional management and vaccination of ali animais using vaccines of high immunogenic power. Six commercial vaccines containing in its formulation the epsilon toxoid of C. perfringens type D were sorogically evaluated. Eighty four female goat kids, whose mothers had no previous vaccination history against clostridioses were used. They were divided into six groups of 14 animais each. The animais of the control group didn't receive any vaccine dose and the animais from the groups 1 to 5 received two vaccine doses, The first vaccine dose was applied at 45 days of life (day zero) and the second dose at 75 days (30 days after the first dose). Blood samples were collected from the goat kids at the days zero, 30, 60, 90, 120 and 150 after the beginning of the experiment, in order to evaluate the immunologic response. The Indirect ELlSA technique was used for the quantification of the antibodies against epsilon toxin in the samples of blood serum of the animais. In day zero, no animal presented titre considered protector. The largest number of animais considered protected was found at day 60, in response to the two initial doses of the vaccine (days O and 30, first and second doses, respectively). Only tive animaIs which received the vaccine 1 and one animal which received the vaccine 3 stayed wilh titres of antibodies considered up to 150 days after the first vaccine dose. Based on the results, it was concluded lhat the evaluated vaccines showed small amount of epsilon toxoid in the commercial formulations, a crucial fact for lhe low efficiency of. the vaccines. For commercial reasons, the vaccines against the clostridioses present versatile formulations, with several toxoid types, used for various animal species, which certainly contributed to reduce their effectiveness in preventing the iIInesses caused by the clostridia or their toxins.

Eficiência da recuperação de embriões e os efeitos de consecutivas colheitas sobre o aparelho reprodutor de doadoras da espécie caprina.

Resumo: 0 objetivo deste experimento foi comparar a eficiêncÎa e o efeito de consecutivas colheitas de embriões, por três diferentes métodos (transcervical-T1, laparoscopia-T2 e laparotomia-T3), sobre a atividade reprodutiva de doadoras da espécie caprina. Utilizaram-se 10 cabras em cada método (T1, T2 e T3), sendo as colheitas de embriões repetidas três vezes consecutivas nas mesmas fêmeas, com intervalo de 56 dias. As fêmeas foram sincronizadas com esponjas vaginais impregnadas com 60 mg de acetato de medroxiprogesterona durante 10 dias e 100 ug de cloprostenol aplicados pela via lM no oitavo dia da sincronizaçao. No 8º dia, iniciou-se a superovulaçao com 250 UI de FSH de origem suína, divididas em oito doses decrescentes, aplicadas em intervalo de 12 horas. As fêmeas foram acasaladas e as colheitas de embriões realizadas no 5° ou 6° dia após a ultima cobertura. Após 56 dias da terceira colheita de embriões, foram realizados o abate e a necrópsia das doadoras. 0 tempo necessário para a a colheita de embriões em cada método foi de 21 minutos e 32 segundos; 37 minutos e 14 segundos e 56 minutos e 22 segundos, respectivamente, para TI, T 2 e T 3 (p<0,0I). A maior taxa de recuperaçao da soluçao de lavagem foi no T3 (83,7%), seguido por T2 (72,2%) e TI (64,3%) (p<0,05). As taxas médias de recuperaçao dos embriões foram 57,1; 81,1 e 27,3% para TI' T2 e T3' respectivamente, com variaçao entre 0-100%. A taxa de recuperaçao de embriões sofreu influência de varios fatores, com a presença de corpos luteos regredidos, a taxa de ovulaçao e a presença de aderências no sistema genital, mas, isoladamente, a taxa de recuperaçao de embriões foi satisfatória nos três métodos. 0 T1 causou eversao do endométrio e aderência entre o corno uterino e o epíploo em uma unica fêmea, o T2 causou eversao do endométrio em 30%, 40% e 60% e aderências do sistema genital em 10%, 10% e 70% das fêmeas à 1 a, 2a e 3a colheitas, respectivamente. 0 T3 causou aderências no sistema genital em 80% das doadoras ; após a primeira e 100% após a segunda colheita. 0 T1 e o T2 permitem o usa de doadoras em repetidas colheitas de embriões, o que nao ocorre com o T3, que causa aderências no sistema genital e órgaos circunvizinhos em 100% dos casos.
