TLDR
Semen collection in turkeys is more favourable when harvested once per week since semen concentration declines progressively with increase in the ejaculation frequency.Abstract:
A study was carried out at the Abubakar Tafawa Balewa University Farm, Bauchi (February - May, 2002) to investigate the effect of frequency of ejaculation (once, twice and thrice per week) on semen traits in exotic and local turkeys. The results showed that ejaculate volume, live spermatozoa, abnormal spermatozoa, sperm concentration and total sperm per ejaculate were significantly (P<0.05) higher in exotic than local turkeys, values being 0.32±0.02 vs 0.17±0.02ml, 83.83±1.33 vs 80.67±1.33%, 11.19±0.73 vs 13.61±0.73%, 4.66±70.73 vs 2.81±74.93 x 10 and 97.72±9.86 vs 50.81±10.45 x 10 . It was also shown that 9 9 sperm concentration was the only variable significantly affected (P<0.05) by frequency of ejaculation. The interaction of breeds and frequency of ejaculation also favoured (P<0.05) the exotic breed at lower frequency of ejaculation. Semen collection in turkeys is more favourable when harvested once per week since semen concentration declines progressively with increase in the ejaculation frequency. The exotic have superior genetic make-up than the local turkeys in terms of their reproductive potential.read more

TL;DR: The Yankasa breed was more heat-tolerant than the Uda and Balami breeds of sheep and the combined effects of temperature and humidity had a greater influence on the animals than their separate effects.

TL;DR: This study shows that although TSR was not affected by daily semen collection, EGR was depleted by 70% of the rested value when the turkeys were ejaculated daily for 15 days.

TL;DR: The heat-soluble proteins isolated from wheat seed embryos are capable of protecting turkey sperm during in vitro storage and could potentially improve long-term storage of sperm from other species.
