Abstract |
The study was carried out to evaluate the effects of heated and unheated
coconut milk (HCM, and UHCM, respectively) as extenders for indigenous
cock semen and to compare the effects of these diluents to sodium
citrate (Na-citrate), and physiological saline (saline) on semen quality
parameters including storage time under ambient conditions. A total of
65 chickens: 50 hens (55 weeks of age and actively in lay) and 15 cocks
(~2 years old, 1.8-2.0 kg body weight (P<0.05) held in individual cages
were used for the study which lasted for 5 wk. There were 5 treatments
(10 hens and 3 cocks each) namely raw semen (T1), Na-citrate (T2), HCM
(T3), UHCM (T4) and saline (T5). There were significant (P<0.05) main
effects of dilution, diluent type and storage time and interaction
effect of diluent type × storage time on the traits measured. SPM and
TMS were highest for semen diluted in Na-citrate, HCM and saline
compared to UHCM. Semen diluted in Na-citrate and HCM gave highest
fertility compared to saline and UHCM. Hatchability was highest for
semen diluted in Na-citrate followed by HCM. Undiluted semen and semen
diluted in UHCM differed significantly (P<0.05) in their effects on SPM,
fertility and hatchability of eggs. SPM was 0.00% by 80 min post
dilution in UHCM extender but 52.9±1.69, 40.5±0.90, and 40.2±0.77% for
Na-citrate, HCM, and saline, respectively at 100 min. Heated coconut
milk could therefore be used as diluent for semen proposed for short
duration (≤ 100 min).
