Performance Of Broilers Sexes Separately Versus Combined In Cages - 1982

The aim of the experiment was to study the performance of broilers sexes separately versus combined in cages. Ninty, day-old chicks (Pilch) were reared for the experiment. The chicks were first divided into three groups of thirty each (30 males, 30 females and 30 mixed). Each group was further divided into three replicates of ten chicks. A commercial ration was fed to the birds and was reared in batteries. The environmental conditions were similar for all groups. Daily feed consumption record was maintained and the birds were weighed at the end of 6th, 7th and 8th week.
At the end of 8th week gained an average live weight of 2332.00, 2315.5 and 2339.5 grams, females 1892.0, 1927.5 and 1956.0 grams and mixed 2152.0, 2097.0 and 2111.0 grams, per bird, with a feed conversion ratio of 2.228, 2.198 and 2.248 for males, 2.214, 2.228 and 2.207 for females and 2.215, 2.205 and 2.231 for mixed, respectively.
The data collected was statistically analysed which indicated a non-significant difference in weight gain amongst the replicates of the same groups and a highly significant difference in the weight gain of different groups. A non significant difference was also observed between the average weight gains of sexed and combined broilers. A non significant difference of feed conversion ratio was observed among the replicates and groups.
As the separation of sexes has no significant effect on weight gain and feed efficiency hence to save the extra cost of sexing, the practice of rearing the broilers sexes separate cannot be recommended.
