Abstract
- Com o objetivo de avaliar o sêmen de caprinos congelado em diluidor à base de TRIS contendo baixa quantidade de gema de ovo, foi feita a análise da motilidade retilínea e progressiva logo após o congelamento e após 4 anos de estocagem em nitrogênio líquido, resultando respectivamente em 38,2 ± 7,47% e 31,43 ± 13,55%. Foi feita a sincronização do cio de 16 cabras com esponjas intravaginais impregnadas com progesterona e aplicações de PMSG no nono dia. No 11º dia as esponjas foram retiradas e após 46 horas foi feita a inseminação artificial com palhetas estocadas por 4 anos. Houve 31,2% de não-retorno ao cio. O diluidor à base de TRIS contendo baixa quantidade de gema de ovo se mostrou eficiente quanto à preservação dos espermatozóides quando avaliados in vitro através da motilidade retilínea e progressiva e in vivo através da inseminação artificial. Aiming to evaluate frozen goat semen in TRIS diluent with low egg yolk addition, progressive motility was evaluated soon after freezing and again 4 years later, resulting in 38.2 ± 7.4% and 31.4 ± 13.5%, respectively. Sixteen goats were oestrus synchronized through progesterone impregnated intravaginal sponges followed by PMSG injection on day 9. Vaginal sponges were withdrawn on day 11, with goats being artificially inseminated 46 hours later with semen frozen in straws and stocked during 4 years in liquid nitrogen. The nonreturn rate attained 31.2%. TRIS diluent with low egg yolk addition was considered as efficient in relation to frozen sperm evaluated both in vitro through progressive motility as in vivo through artificial insemination.
