This study aimed to evaluate physical aspects of the semen and sexual behavior of Moxotó breed goats at different ages. Two males Moxotó goats, ages 4 and 7, represented by (1) and (2) respectively, and twenty-six (26) female goats as mannequins, were used. The breeders were subjected to sexual behavior evaluation by measuring of reaction time to the female in estrus, which were recorded the patterns of behavior (courtship with paw, emission of sounds, tongue exposure, exposure penis exposure, smell the urogenital female and Flehmen reflex) performed in two shifts (morning and afternoon) during the months of February to April 2010, totaling 50 observations. To assess the physical aspects of semen collections were performed twice on each breeder at the beginning and end of the observation period. There was no difference in reaction time and the number of jumps in terms of shifts and breeders. The frequency of behavioral events in relation to shifts evaluation did not differ. The emission of sounds (EMS) and exposure of the tongue (EXL) was expressed more often by the oldest breeder (2). Regarding the assessment soundness, the average values for the parameters studied as motility, vigor, pathology and sperm concentration, results were favorable to the breeder (1). The study of behavioral patterns during the courting stage is an indispensable tool in predicting the reproductive potential of male goats; however, other aspects within the reproductive management should be evaluated in combination. Key words: Behaviours events, ethology, reaction time ResumoEste estudo objetivou avaliar o comportamento sexual e aspectos físicos do sêmen de reprodutores caprinos da raça Moxotó. Foram utilizados dois reprodutores, com idades de 4 e 7 anos, representados por (1) e (2), respectivamente, e vinte e seis (26) cabras como manequins. Os reprodutores foram submetidos à avaliação do comportamento sexual pela medida do tempo de reação frente à fêmea em estro, onde foram registrados os padrões de comportamento (cortejo com a pata, emissão de sons, exposição da língua, exposição do pênis, cheirar a região urogenital da fêmea e reflexo de flehmen) realizados em dois turnos (manhã e tarde) durante os meses de fevereiro à abril de 2010, totalizando 50 observações. Para avaliação dos aspectos físicos do sêmen, foram realizadas duas coletas em cada reprodutor no início e fim do período de observações. Não houve diferença quanto ao tempo de reação e ao número de saltos em função dos turnos e reprodutores. A freqüência dos eventos comportamentais em relação aos turnos de avaliação não diferiu. A emissão de sons (EMS) e exposição da língua (EXL) foi expresso mais vezes pelo reprodutor mais velho (2). Com relação à avaliação andrológica os valores médios encontrados para os parâmetros estudados como motilidade, vigor, patologia e concentração espermática, apresentaram resultados favoráveis ao reprodutor (1). O estudo dos padrões comportamentais durante a fase de cortejo é uma ferramenta indispensável na predição do potencial reprodut...

Poincianella pyramidalis (catingueira) is a toxic plant associated with abortions, embryonic losses and malformations in goats and laboratory animals. Outbreaks and sporadic cases of spontaneous intoxication in sheep have been reported in the last five years in the agreste of Pernambuco. Due to the occurrence of these spontaneous cases and the lack of researches in sheep, an experimental study was carried out to evaluate the teratogenic effects of P. pyramidalis on sheep. In the experiment, 16 female and three male sheeps, mixed breed, were used. Females were divided in four groups, with four animals per group and maintained in individual stalls, underwent estrus synchronization and mating by natural mating and after 30 days the diagnosis was made to confirm gestation. Groups were named group 1 (G1), group 2 (G2), group 3 (G3), and group 4 (G4). In G1 (control) the ewes were fed with 1% of concentrate supplementation (CS) based on live weight (LW) and 2% of maize silage (MS) with a daily intake of 3% dry matter (DM) based on LW. In G2 feeding was constituted of 1% of CS based on LW and 2% of forage, including 2% of roughage, 50% was hay of P. pyramidalis and the other 50% of DM. In G3 feed was constituted of 1% of CS based on LW and 2% of roughage. Among these 2% of roughage, 80% was hay of P. pyramidalis and the other 20% of DM. In G4 the sheep were fed with 1% CS based on the LW and the roughage consisting of 100% P. pyramidalis hay.

RESUMO:O carcinoma epidermoide ocular é uma neoplasia maligna de grande incidência em bovinos de regiões tropicais. Animais com região periocular despigmentada e com lesões prévias, associados à exposição prolongada a raios ultravioleta, possuem maior predisposição ao desenvolvimento neoplásico, sendo de difícil ocorrência em animais de região periocular pigmentada. O presente relato trata de um bovino de região periocular pigmentada com histórico de trauma ocular prévio e com desenvolvimento de carcinoma epidermoide ocular recidivante. Ao exame externo, observou-se que o tumor apresentava área central com extensa necrose, de odor fétido, coloração amarelada e de aspecto granular, presença de tecido escleral e infiltração craniana pelos tecidos neoplásicos. Os achados microscópicos foram compatíveis com carcinoma epidermoide pobremente diferenciado, com presença de grupos de células pleomórficas confluentes com pouca queratinização individual e muitas mitoses.Palavras-chave: Neoplasma, olho, trauma ocular, raios ultravioleta. Ocular epidermoid carcinoma in bovine with pigmented periocular region -Case report ABSTRACT:The ocular epidermoid carcinoma is a malignant neoplasm of high incidence in tropical cattle. Animals with depigmented periocular region and previous injuries associated with prolonged exposure to ultraviolet light has a greater predisposition to neoplastic development, being difficult to occur in animals with periocular region pigmented. This report describes a bovine with periocular region pigmented with prior ocular trauma history and development of ocular epidermoid carcinoma recurrent. In the external examination, it was observed that the tumor showed a central area with extensive necrosis, foul-smelling, yellowish coloration and granular appearance, presence of scleral tissue, and cranial infiltration by neoplastic tissues. The microscopic findings were consistent with the poorly differentiated epidermoid carcinoma that presents pleomorphic cells with confluent groups, little individual keratinization, and many mitoses.
