EFFECT OF STARVATION ON SEMEN QUALITY TRAITS AND SOME BLOOD CONSTITUENTS IN TWO TURKEY BREEDS AND THEIR RECIPROCAL CROSSES
The aim of this work was to study the genetic differences for the semen quality traits for Black Bronze and White Holland turkey breeds and their crosses which were reared under some nutritional regiment and Egyptian environmental conditions. Sixty Black Bronze (BB) and sixty White Holland (HH) females were mated with ten toms from the same breeds. Each torn was artificially inseminated with three females from the two mentioned breeds to obtain three successive hatches. The results obtained showed that purebred Bronze Holland revealed the highest reduction for sperm concentration as compared with crossbreeds (81-1 & HB) at seven days of the end of starvation. The effect of starvation stress was more pronounced for sperm concentration fourteen days as compared with seven days after the end of starvation. The BH crossbred had the lowest GOT level, highest abnormal sperm and higher semen volume when fed 12 or 17% protein before start of starvation, while HB crossbred had the lowest either dead sperm or abnormal sperm per 200 sperm. Generally a reduction in the level of GPT due to starvation was noted. The reduction due to starvation was 1.12 U/L regardless of the genotype. With respect to total protein level, total serum protein for toms fed on 17% protein were significantly higher (P<0.05) than those fed on 12% or 14% protein level either before or after starvation.
