Two semen extenders were compared for their ability to maintain viability of horse semen during 24 hours of cold preservation, and for the pregnancy rate after artificial insemination. In the experiment 1, five ejaculates from three stallions were split-diluted in either a skimmed milk-based extender (Kenney extender) or a glycine egg yolk-based extender (Foote extender) and cooled at 6-8 ºC for 24 hours. Semen samples stored in Kenney extender for 24 hours had higher motility and spermatic vigor compared with […]

The objective of this study to verify the physicochemical quality of commercial washed and unwashed eggs, experimentally inoculated on the shell with Pseudomonas aeruginosa and stored at 5 and 25 ºC for 30 days. A total of 384 eggs, classified as large, from light Dekalb White laying hens at 30 to 40 weeks of age, were used. The experimental design consisted of two blocks in a 2 × 2 × 2 factorial arrangement (contamination, washing, and refrigeration) with six replicates. […]

The objective of this study was to evaluate the effect of the addition of oil sources and levels of vitamin E supplementation in the rations on the characteristics of boar semen cooled at 17 and 5ºC. It was used twenty-four Dalboar 85 boars distributed in a complete random design, in a 2 x 3 factorial scheme, with two sources of oil (soybean and salmon) and three levels of antioxidant (150, 300 and 450 vitamin E mg/kg). For animals under supplementation […]

The experiment was conducted in order to evaluate the effect of 3 diluents BTS+KCl – D1, BTS+2KCL – D2 and BTS+Sodium Citrate – D3) and three different times (hour 0, 72 hours and 144 hours) in Piracanjuba (Brycon orbignyanus) semen at 4°C. The assay aimed to test usefulness of BTS (Betsville Thawing Solution) diluent medium, added to Sodium citrate and Potassium clorate, in maintenance of spermatic immobility and of its conditions to conserve semen characteristics as spermatic motility rate and […]
