Resumo: Objetivou-se com este estudo investigar a participação de Toxoplasma gondii em falhas reprodutivas em pequenos ruminantes de criatórios situados na Zona da Mata e no Agreste do Estado de Pernambuco e que apresentavam histórico de distúrbios reprodutivos. Foram selecionadas 12 propriedades das quais se coletaram amostras de 262 animais, sendo 167 caprinos e 95 ovinos. Realizou-se a pesquisa de anticorpos anti-Toxoplasma gondii, utilizando-se a técnica da Imunofluorescência Indireta (RIFI). Foram aplicados questionários investigativos nas propriedades visitadas para identificar os fatores de risco associados à infecção. Em 100% das propriedades foram encontrados animais soropositivos. Para T. gondii, das 167 amostras de soro caprino analisadas, 31,7% foram positivas, enquanto que na espécie ovina, das 95 amostras, 16,9% foram positivas. Para a espécie ovina, não foram observadas associações significativas. Para os caprinos, houve associação significativa (p<0,05) para as variáveis: manejo intensivo (OR=2,40), exploração leiteira (OR=2,10), animais procedentes de outros estados (OR=7,89) e monta natural (OR=5,69). Conclui-se que a infecção pelo T. gondii encontra-se disseminada nos rebanhos de caprinos e ovinos estudados e que medidas sanitárias devem ser adotadas para controlar os fatores de risco identificados neste estudo.

Abstract: This study was conducted to investigate the participation of Toxoplasma gondii in reproductive failure in small ruminants raised in the Litoral/ Zona da Mata and Agreste of the State of Pernambuco, Brazil. Twelve flocks were selected from which 262 samples were collected, 167 from goats and 95 from sheep. Indirect Imunofluorescent Antibody Reaction (IFA) technique was used to detect antibodies anti-Toxoplasma gondii. A questionnaire was applied in flocks to identify risk factors associated with infection. Positive animals were found in 100% of the farms. Among 167 samples of goat serum analyzed, 31.7% were positive, whereas from 95 samples of sheep, 16.9% were positive. Results of brucellosis tests were negative for 100% of analyzed samples. For sheep, no significant association was found; however, for goats, there was a significant association (p<0.05) for intensive handling (OR=2.40), milk exploration (OR=2.10), animals originating from other states (OR=7.89) and natural breeding (OR=5.69). It was concluded that infection for T. gondii is spread in studied goat and sheep flocks and that sanitary measures must be adopted to control risk factors for infection.

Abstract: Hormonal oestrus induction treatment is an important tool for the success of reproductive biotechniques in anoestrus goats. In the nonbreeding season, oestrus induction can be performed by the use of several protocols, including those varying in their duration. This study aimed to compare short-term (for either 5 or 6 days) progestogen-based oestrus synchronization protocols in dairy [Toggenburg (n=12) and Saanen (n=12)] goats during the nonbreeding season. This study was performed in Minas Gerais State, Brazil (21°35?S and 43°15?W), with 12 nulliparous (12?14 months old) and 12 pluriparous (2?4 years old in final third of lactation) goats, all with body condition scores (BCS) of 3.0 to 3.5. They were equally assigned to both treatments according to their order of parturition, BCS, and breed. On a random day (Day 0), 24 goats received an intravaginal device of 60mg of medroxyprogesterone acetate (Progespon®, Zoetis) which remained for 5 (G5; n=12) or 6 (G6; n=12) days. On Day 5, goats from both groups received 30µg of cloprostenol intramuscularly (IM) (Prolise®, ARSA S.R.L.) and 200IU of equine chorionic gonadotrophin (eCG) IM (Novormon®, Schering Plough Animal Health). Both groups received cloprostenol and eCG on the same day (regardless of device removal) to ensure they were administered at the same follicular wave. Both device insertion and removal were performed in the morning. Ultrasound evaluations were performed every 12h from device removal to ovulation detection. Ovulations were considered as the average interval between the last observation of follicles and the first exam in which it was no longer seen. The normal distribution of variables was determined by Shapiro-Wilk test and homocedasticity by Levene?s test. All variables were not normally distributed and thus analysed by Mann?Whitney U test, with P<0.05 considered significantly different. Values are presented in median±interquartile range. There was no difference between G5 and G6, respectively, in the interval to oestrus (48.0±0.0 vs. 48.0±12.0h), interval from oestrus onset to ovulation (18.0±9.0 vs. 18.0±12.0h), interval from device removal to ovulation (66.0±18.0 vs. 66.0±24.0h), number of ovulated follicles (2.0±2.0 vs. 2.5±2.0), or mean diameter of ovulated follicles (6.6±1.6 vs. 6.6±1.4mm). All ovulations were detected in the morning. In conclusion, our data demonstrate that short-term hormonal treatment for 5 or 6 days is similarly efficient to induce synchronous oestrus in Saanen and Toggenburg goat.
