Brucella ovis REO 198 natural and experimental infection in Santa Inês rams from Brazil

B. ovis pathogenicity was evaluated in experimentally inoculated and naturally infected rams. Ten animals were submitted to simultaneous conjunctival and intrapreputial inoculation with 2x109 CFU/ mL of B. ovis REO 198. After that, animals underwent physical examination and blood samples were collected for serology every week. Positive serology results started to be observed in the 3rd week, with fluctuations in titers. Clinical changes began in the 5th week after inoculation and were associated with positive serology in the acute phase of the disease. Presence of B. ovis in semen and urine culture was intermittent. Three non-inoculated animals showed natural infection. B. ovis was shed twice in semen of one serology-negative animal. The study underscored the pathogenic characteristics of B. ovis REO 198 in Santa Inês rams, as well as the importance of animals as potential sources of infection.

Performance, survivability and carcass traits of crossbred lambs from five paternal breeds with local hair breed Santa Inês ewes

The present study aimed to evaluate the performance, survivability and carcass traits of crossbred lambs. Data from 299 lambs born to 209 ewes were used. The dams were from a local hair breed (Santa Inês) and five breeds of sires were used: Dorper (DR), Ile de France (IF), Hampshire Down (HD), Texel (TX) and Santa Inês (SI). The lambs were weighed at birth, weaning and slaughter. Fasting body weight, skin thickness, hot and cold carcass weight, carcass yield and carcass length were measured at slaughter. Carcasses were separated into commercial cuts: neck, shoulder, rib, belly, loin and leg. Leg length and circumference were measured. Analyses of variances using MIXED procedure in SAS® were carried out for weights and carcass traits. Factor, discriminant and canonical analysis were carried out. Mortality data of animals from birth until slaughter was analyzed using logistic regression. The HD animals had the highest mortality rate. TX lambs had similar growth rate and survivability compared to DR and IF and had better carcass traits than these genetic groups. Therefore, this breed can be used as paternal breed to crossbreeding with Santa Inês dams. Santa Inês animals did not differ in growth from birth until slaughter compared to crossbred animals, which highlights the potential of this naturalized breed for meat production. Moreover, there is a great variability inside this breed for carcass and growth traits which may undergo great improvement through selection programs. © 2013 Elsevier B.V.

Frequency of estrus in santa inês, texel and ile de france ewes in the northwest of Paraná state, Brazil

The incidence of estrus in nulliparous Santa Inês (n = 16), Texel (n = 16) and Ile de France (n = 15) ewes fed two levels of crude protein (CP, 12 or 16%) was monitored from July 2005 to December 2006, and seasonality in the Santa Inês breed in the south of Brazil was characterized. The solar radiation data were recorded daily, and samples of blood were collected biweekly for determination of the plasma concentration of progesterone in Santa Inês lambs at, on average, 11±1 months of age. The female Santa Inês lambs, in the experimental period, stayed among teaser rams with a powdered-dye-ink mixture placed on their chest to mark the females that accepted to be mounted. Santa Inês ewes did not manifest estrus in the firstfortnightofNovemberandinDecember2005,norinthelastfortnightofDecember2006.Estrusactivitywasnotobservedon any of the three breeds in October 2006. Breeds differed at the level of 12% CP. Santa Inês and Ile de France females did not differ as for the probability estrus manifestation and both presented higher probabilities then Texel.

The concentration of plasma progesterone inSanta Inês ewes during the spring of 2005 and 2006 indicated that there is difference between 12% CP (0.68±1.32 ng/mL) and 16% CP (1.28±1.99 ng/mL) and between the years 2005 (0.39±0.78 ng/mL) and 2006 (1.47±2.08 ng/mL), demonstrating the anestrous seasonality of Santa Inês in South Brazil. © 2013 Sociedade Brasileira de Zootecnia.

In vitro and in vivo evaluation of the activity of pineapple (Ananas comosus) on Haemonchus contortus in Santa Inês sheep

The development of resistance to anthelmintics has prompted research into alternative methods of controlling intestinal nematodes in ruminants. This study aimed to assess the activity of Ananas comosus on Haemonchus contortus in Santa Inês sheep. The aqueous extract of pineapple skin (AEPS), bromelain from pineapple stems (B4882) and residue from pineapple processing was evaluated in in vitro and in vivo tests. The enzymatic activity of substances was analyzed by the azocasein method. The egg hatch test (EHT) and larval development test (LDT) were performed using the Embrapa2010 isolate of H. contortus. In the in vivo test, 36 sheep artificially infected with H. contortus were divided into six groups: G1: 2g/kg BW of the aqueous extract administered for three days; G2: 2g/kg BW of the industrial pineapple residue for 60 days; G3: 180mg/animal of bromelain in a single dose; G4: negative control I; G5: positive control (levamisole phosphate); and G6: negative control II. The eggs per gram (EPG) in the feces were counted till 28 days after treatment. LC50 and LC90 were obtained by the probit procedure, while the in vivo test results were analyzed by GLM. The aqueous extract in the in vitro and in vivo test, the bromelain and industrial residue presented 0.102, 0.157, 1.864 and 0.048 enzyme units/mL, respectively. In the egg hatch test, the LC50 and LC90 were respectively 31 and 81mg/mL for the aqueous extract and 0.50 and 2mg/mL for bromelain. In the larval development test, the LC50 and LC90 were respectively 1.7 and 7.3mg/mL for the aqueous extract and 0.019 and 0.086mg/mL for bromelain. In the in vivo test, the general efficacies of the treatments in relation to the negative control were 22.6%, 42.2%, 3.65% and 89% for the aqueous extract, industrial pineapple residue, bromelain and positive control respectively. The transformed EPG values were 3.19±0.59, 3.32±0.25, 2.85±0.66, 3.44±0.50, 2.28±0.93 and 2.75±0.94 for the aqueous extract, industrial residue, bromelain, negative control I, positive control and negative control II respectively. The results for all the treated groups differed significantly (p<0.05) from the positive control, and although the residue presented efficacy of 42.2%, there was no statistical difference (p>0.05) in relation to the negative control. Therefore, both the aqueous extract and bromelain were effective in vitro, but showed reduced anthelmintic efficacy in vivo. For the pineapple residue, the 42.2% in vivo efficacy in reducing the EPG and the possibility of reducing environmental contamination through reuse of industrial residue indicate it can also be useful for control of this parasite. © 2013 Elsevier B.V.

Rendimentos de carcaça, cortes comerciais e não-componentes da carcaça de cordeiros Santa Inês alimentados com feno de erva-sal e concentrado

This work aimed to evaluate the carcass yields, commercial cuts and non-carcass components of Santa Inês lambs fed with 30, 40, 50 or 60% of oldman saltbush hay with concentrated. Were used 32 castrated lambs at 8 months old and initial body weight of 22 + 1.97kg, housed individually and slaughtered after 60 days of feedlot. The weights of hot and cold carcass decreased linearly with the inclusion of saltbush hay in the diet, however, there was no effect for true carcass yield and commercial cuts: shoulder (19.26%), neck (8.52%) ribs (26.57%) and leg (33.88%). There was a linear decrease for ribeye area and fat thickness when the level of hay in the diet increased. The weights and yields of skin, liver, heart, kidneys with perirenal fat, omental and mesenteric fats decreased linearly with the inclusion of hay in the diet, while the content (%) of gastrointestinal tract increased. The increased proportion of saltbush hay in the diet of lambs provided adequate true carcass yield and commercial cuts, however, reduces the ribeye area and fat thickness, important measurements in the qualitative evaluation of the lamb's carcass.

Performance, carcass characteristics and non-carcass components of Texel × Santa Inês lambs fed fat sources and monensin

Performance, carcass, non-carcass and commercial cuts and components of Texel × Santa Inês crossbred lambs, managed in confinement and fed diets based on soybean oil, soybeans and a conventional diet, with or without the use of monensin (78 ppm dry matter basis) were evaluated. Thirty-six Texel × Santa Inês lambs (18 males and 18 females) were managed in intensive systems. Animals were slaughtered after 87 days of confinement, and performance, carcass characteristics, weight and percentages of carcass and non-carcass components were evaluated. The animals fed the control diet had heavier carcass and parts than animals fed soybean, while the oil diet did not differ from the controls in most parameters. The animals fed soybean showed lower intake kg dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF) and metabolizable energy (ME) compared with animals fed the control diet, increased ether extract (EE) intake in kg, % body weight (BW) and metabolic weight (MW) and did not differ from the soybean oil diet. Animals receiving monensin had lower DM intake, OM, CP, EE, NDF, gross energy (GE) regardless of the expression, % kg BW, or % PM, than the animals that did not receive the additive. Males produced better and had heavier cuts than the females; the latter deposited subcutaneous fat earlier. Animals that received oil or soybean showed greater body weight and small intestine percentage. Soybean oil intake did not improve performance, carcass weights or parts of Santa Ines × Texel lambs in confinement. Soybeans at 15% dry matter reduced energy intake and lamb performance. The use of monensin at 78 ppm on a dry matter basis is not recommended for lambs in confinement, especially if associated with oil or soybeans that may harm animal performance.

Diagnóstico y características del queratocono mediante topografía corneal en el Hospital Santa Inés. Cuenca 2012-2014

Antecedentes: El Queratocono es un problema oftalmológico que se presenta en la edad adulta temprana, es generalmente bilateral y afecta indistintamente a ambos sexos. Representa la primera causa de trasplante corneal en países desarrollados. En el Ecuador existe escasa evidencia acerca de esta patología. Objetivo general: Establecer el diagnóstico y características del queratocono en pacientes con astigmatismo mayor a 1 dioptría (D) mediante topografía corneal en la consulta externa de oftalmología en el Hospital Santa Inés de Cuenca. Metodología: Se realizó un estudio retrospectivo, observacional y descriptivo. Se estudió las topografías corneales de pacientes con astigmatismo mayor a 1 Dioptría que asistieron a consulta externa de oftalmología en el Hospital Santa Inés de Cuenca entre enero del 2012 a diciembre del 2014. Los datos fueron recolectados del Topógrafo “Atlas 9000” y mediante el programa SPSS Statistics versión 20 se realizó el análisis de los datos. Para el diagnóstico se utilizaron los criterios de Rabinowitz y McDonnell modificados, y para su clasificación, se utilizaron los criterios queratométricos. Resultados: La frecuencia de queratocono fue 28,6%, el 53.1% fueron hombres y el 46.9% mujeres, fue bilateral en el 56.3% de los casos. El grupo de edad más afectado fue el de 20 a 39 años. El 75% de pacientes con queratocono presentó astigmatismo severo y el grado de queratocono incipiente fue el predominante con el 46,9%. Conclusiones: La alta frecuencia de queratocono, demuestra que nos encon-tramos frente a un grave problema de salud que muchas veces pasamos por alto y que compromete seriamente a la población joven
