Effect of metabolizable energy and crude protein levels on performance, fertility, hatchability and egg quality of Rajasri breeder birds

This study investigated the impact of different levels dietary energy and crude protein on productive performance, egg quality, reproductive parameters in Rajasri breeder birds during a 12-week period between 25 to 36 weeks age. A total 648 were divided into nine treatments, each with eight replicates, following 3 × factorial arrangement three metabolizable (2400, 2500, 2600 kcal ME/kg) (14, 15, 16%). The results indicated that had significant effect feed intake, weight, body yolk colour, shell thickness. However, there was no production efficiency. An increase weight observed as increased diet, but difference albumin index, shape index. Yolk colour higher ME/kg fed group. Furthermore, found ME CP percentage shell, thickness decreased increased. There also density breaking strength, fertility, hatchability eggs set (TES), fertile (FES). Based findings, concluded require diet containing 2400 14% for optimal performance.
