Comparative study of the hatching rate, and the weight performance of IF from the Brahma rooster cross crossed with local hens, Isa Brown and Dekalb

Abstract

The objective of this work is not only to verify the hatching rates of eggs from the 3 breeds but also the weight performance of F1 from crosses and the physical appearance of the offspring through the plumage. The chick mortality rate was taken into account to assess adaptation to climate change. The goal is to offer farmers efficient and acclimatized subjects. The study was carried out in the Urban Commune of Tillabéry which is located between the coordinates 1 ° and 2 ° East longitude; 14 ° and 16 ° North latitude. During this study, nineteen (19) hens and three (3) roosters were used. The work focused on 5 outbreaks. Out of 351 eggs the total hatching rate is 41.88%. This rate varied according to the races: 56.33% for local breeds and 40.44%, 36.45% and 35.41% respectively for Isa Brown, Brahma and Dekalb. On the other hand, the mortality rate is high in the Laying breed (Isa Brown) with 39.62% against 28.30% at the level of Brahma, clearly lower at the level of the local breeds 15.09% and Dekalb 16.98%. For weight growth 119 chicks were monitored. The mean hatching weight is 34.7 ± 0.5 g (N = 119). Growths vary depending on the sex and the breeds and females used for the crossbreed.
