BookPublisher: 1983Subject(s): Department of Livestock ProductionDDC classification: 0018,T Dissertation note: The main objective of this research was to examine the possibility of using skimmed milk and whole milk as diluents of fowl semen under the local environment. The research was carried out on 56 weeks old hens at the poultry Research Institute, Rawalpindi. The birds were trap nested in individual cages and cages were arranged in three tiers. The birds were exposed to 16L: 8D. Feed and water were available at all times. Study was executed in two phases.
In the first series of trials, skimmed milk was used in five different dilutions comprising 1:5, 1:10, 1:15, 1:20 and 1:25 undiluted semen (Treatment A) served as control group. The experiment was repeated four times to remove any experimental error and to minimize variability between the trials. The hatchability of eggs was maximum in the control group, and it was observed to be statistically significant (P<0.01) than all other competitive treatments. The skimmed milk dilutions gave poor hatchability although hatchability increased with the reduction in the dilution ratio.
The second phase of trials consisted of two trials and each trial had three treatments, i.e. undiluted semen (A), skimmed milk dilution 1:2 (B) and whole milk dilution 1:2 (C), treatment B was included in the trials to make the skimmed milk studies comprehensive and to compare it with the whole milk as diluents of chicken semen. The hatchability of eggs in treatment A and C was substantially higher than the skimmed milk group (Treatment B).
The number of infertile eggs in the skimmed milk group was very high and it was significantly (P<0.01) more than all other treatments. This higher infertility could e ascribed to old age of the birds and high temperature (above 40oC) of summer season. This might, therefore, be concluded that the whole milk proved satisfactory diluents of fowl semen while pure skimmed milk gave poor hatchability.
