Sapera goat is a dairy resulting from cross between Saanen buck and an Ettawah doe. These small ruminants are reared by rural households for poverty reduction undernutrition prevention. Breeding of through artificial insemination (AI) technique was expected to accelerate the increase in population. Unfortunately, frozen semen not available yet. This study aims determine effect distance straw li...

The great expectation of the dairy owners from frozen semen industry is quality with high fertility. Many researchers concentrate in this area to produce and However, problem still exists minimize or reduce cryoinjury related damages that occur during process cryopreservation use all kinds additives. success rate additives added variable at a larger scale. Therefore, any new molecules which can...

Aim: This study was aimed to evaluate the sensitivity, specificity, predictive value and accuracy of ultrasonography in pregnancy rate (PR) prediction in Sahelian goats after progesterone impregnated sponge synchronization within the framework of caprine artificial insemination (AI) program in Fatick (Senegal). Materials and Methods: Of 193 candidate goats in AI program, 167 were selected (day ...

Cryopreservation of sperm has many applications in agriculture, biotechnology, and clinical medicine. The spermatozoon is a very specialized cell that loses the ability of biosynthesis, repair, growth and cell division during the final phase of spermatogenesis. Cryopreservation of sperm generally requires a reduction or arrest of the metabolism of cells, thereby prolonging their life. Semen sam...
