POTENTIALS OF EGG-YOLK CITRATE EXTENDER SUPPLEMENTED WITH AQUEOUS GARLIC EXTRACTS FOR POULTRY ARTIFICIAL INSEMINATION

Abstract

An experiment was designed to harness the potential of aqueous fresh and dried garlic extracts supplement in egg yolk extender for rooster semen to improve fertility and hatchability of egg. Aqueous extract of fresh and dry garlic were obtained and supplemented into egg-yolk citrate extender at different inclusion leveis ranging from 0% to 6% and unextended semen (control). A total of 20 Marshal roosters and 160 hens of 40 wks old were used for the experiment. The ejaculate pool of the marshal roosters was collected and pooled, divided into eight equal parts and randomly allotted to the treatment groups, the extenders were diluted with the semen in ratio 2-1. The hens were inseminated with the constituted extenders for three weeks and eggs were collected for the period of two weeks. The eggs were assessed for fertility and hatchability. The result of fertility of hens inseminated with egg yolk-aqueous dry garlic extracts extended semen showed that treatments 7 (5%) compare favourably with treatment I (unextended) with highest fertility percentage value of 80.0%. Aqueous fresh garlic extract inclusions of 2% and 6% had apparently better percentage values compare to unextended treatment. Inclusion of aqueous fresh garlic extracts at 6% in ege-yolk extenders, and 5% inclusion of aqueous dry garlic extract to egg yolk extender are recommended as an extender in roosters’ semen extension.
