Abstract

This paper discusses the development of extenders and techniques for the protection of bird semen during semen preservation. The biochemical mechanisms that influence avian spermatozoa and their relationship with sperm motility are also examined. The effects of different pH levels and diluent...

Abstract

The study was conducted to determine the microbial contamination of semen of Muscovy drakes which were used for artificial insemination. In the microbiological tests, it was observed that 12.50% of the ejaculates obtained were sterile, 43.75% were contaminated to the extent of 1000 mt/ml, 25.00% -...

Abstract

Data were obtained on 20 ♂ and 600 ♀ Bronze and Imperial White turkeys in 1968 and on 10 ♂♂ and 300 ♀♀ in 1969. Semen was collected twice a week. In 688 ejaculates, volume averaged 0.28 ml, concentration of spermatozoa 3450 x 109/ml, sperm resistance 29.9 x 103 ml of 1% NaCl, and pH 7.4. In 4023...

Abstract

866 ejaculates were obtained by massage and vacuum collector from 30 local Bronze ♂♂ Ejaculate volume averaged 0.166 cm*, sperm motility 86.6%, concentration 4332 × 106 spermatozoa/cm3, survival time at 39° C 340 min, and methylene blue reduction time 5.20 min per 1 × 109 spermatozoa. The use of...

Abstract

Data were obtained from 124 ejaculates from 8 Leghorns during 1 yr. Average semen characters are tabulated. Of 5 diluents tested, Alien's Tyrode, and Bone and Tralson's Ringer solutions maintained the greatest sperm survival during storage at 0°-4° C for 24 hrs.-F.S.
