The study evaluated the influence of feed on the reproductive parameters of West African Dwarf and Sahel goats at theTeaching and Research farm of the Federal Polytechnic Bali, Taraba State. A total of 8 bucks from two goats breeds (West African Dwarf and Sahel) were used for the experiment. The 8 bucks were later moved to Vom, for semen collection, using electro-ejaculator. The study lasted for 12 calendar months. They were fed Gmelina and cassava peel meal, Gmelina and cowpea husk, Ficus and cassava peel meal and, Ficus and cowpea husk as experimental treatments (T1-T4), respectively. Goats according to breed were allotted to treatments randomly and treated as factorial experiments. Season had significant (P<0.01) influence on buck parameters (scrotal length and semen qualities). The overall samples collected was 192 on both the breeds on the following parameters; scrotal circumference, semen volume, semen pH, sperm concentration, sperm motility and live cells and the results were 11.91cm, 0.47ml, 6.78ph, 414.92x106, 83.02% and 92.33% respectively. The result was significant for breed, season and treatment for all parameters except live and dead cells for breeds and treatment. Feeding Ficus containing diets resulted in higher semen quality values. Also, semen colour using likert scale was analyzed which resulted to three types of colour (creamy, milky and watery). The colour was evaluated under based on breed, seasons and treatment diets (feeds). The overall results show insignificant differences for all the parameters (feeds, seasons, breeds and reproductive traits) observed.

Pesq. Vet. Bras. 34 (7) Universitária s/n, Patos, PB 58700-970, Brazil. E-mail: mikaeltolentino@gmail.com Forty-two crossbred rams were used, divided according to their scrotal configuration. Twelve of these animals were used to investigate the testicular biometry and scrotal skin histology. The other animals were used to study the spermatic cord. The animals were placed in a group of 21 animals without scrotal bipartition (GEI) and another with scrotal bipartition (GEII) which did not reach 50% of the length of the scrotum's longitudinal axis. In each group, scrotal skin fragments from six rams and spermatic cord fragments from 5 others were collected, processed by routine histological tests and analyzed with a microscope. In 10 rams latex was injected into the testicular artery to obtain vascular molds and the artery length. Comparison of groups GEI and GEII showed no significant statistical differences (p<0.05) between scrotal thickness (epidermis and dermis), histological constituency of the scrotal skin, number of sudoriferous glands per area, scrotal bipartition length or testicular biometric parameters. However, the total length of the testicular arteries of GEI was greater than of GEII (p<0.05). It was concluded from the morphological parameters analyzed that scrotal bipartition in rams did not influence the skin structure, scrotal bipartition or testicular biometry when compared with animals that did not present this characteristic. Further studies should be carried out to elucidate the appearance of this characteristic in rams and whether it is desirable or not for improved production of these animals in warm climate regions.

RESUMO.-Objetivou-se avaliar a influência da estação do ano sobre a estrutura testicular de ovinos SRD. Foram utilizados 10 animais com idade entre dois e três anos. Os testí-culos foram seccionados e fixados em solução de Bouin por 24h. Os fragmentos foram submetidos ao processamento histológico, emblocados em parafina e corados com hematoxilina eosina. Foram avaliadas a proporção volumétrica dos compartimentos testiculares, o diâmetro dos túbulos seminíferos, altura do epitélio seminífero e frequências dos estágios do ciclo do epitélio seminíferos. Os dados foram submetidos à análise de variância a 5% de probabilidade, do programa estatístico SAS 9.0. Os resultados revelaram todos os valores pesquisados sofreram influên-cia da estação do ano. O valor do diâmetro tubular foi de 143,98±17,83 e 170,37±26,64µm, a altura do epitélio seminífero foi de 44,92±9,23 e 50,06±13,61µm e a proporção volumétrica foi de 78,32±13,68 e 80,13±15,14% nos perí-odos seco e chuvoso, respectivamente. A quantificação das células germinativas e de Sertoli mostrou todos os valores foram maiores no período chuvoso quando comparados com o seco. Concluiu-se que a estação do ano interferiu na estrutura testicular, tendo em vista que todos os valores da proporção volumétrica dos componentes testiculares mostraram diferença significativa entre as estações do ano, pois os valores foram mais acentuados no período chuvoso. To evaluate influence of the year season related with the testicular structure of cross bred sheep, the testes of ten 2 to 3-year-old sheep were sectioned and fixed in for 24 hours in bouin's solution. The fragments were subjected to histological processing, embedded in paraffin and stained with hematoxylin-eosin. The volumetric proportion of testicular compartments, the seminiferous tubules, seminiferous epithelial height and frequency of the seminiferous epithelium stages of the cycle were evaluated. Data were subjected to analysis of variance at 5% probability. The results showed that all values studied were influenced by year's season. The tubular diameter was 143.98±17.83 and 170.37±26.64μm, the seminiferous epithelium height was 44.92±9.23 and 50.06±13.61μm, and the testicle parenchyma volume density was 78.32±16.68 and 80.13±15.14% in the dry and rainy periods, respectively. The germ cells and Sertoli cells quantification showed that all values were higher in the rainy season compared with the dry season. It can be concluded that the year season interfered in the testicular structure, given that all values showed significant differences between the seasons, as the values were more pronounced during the rainy season.
