Khan Journal of Animal and Plant Sciences JAPS 20142014/10/01 24 5 1276-1282 1018-7081 NA <p>The objective of current study was to assess the effect of moulting on productive efficiency in Aseel chickens at different phases of age. A total of 168 hens, 42 from each of four varieties (Mushki, Lakha, Mianwali and Peshawari) divided into 3 age groups, young (50-67 weeks), medium (80 -97 weeks) and old (115-132 weeks) were maintained in cages during pre and post-moult phases. The data thus collected during both the phases were subjected to analysis of variance in Randomized Complete Block Design. The results showed that overall productive&nbsp; &nbsp;efficiency remained better in post-moult as compared to pre-moult phase. Mushki showed significantly higher egg production, egg mass, egg weight, and better FCR/ dozen eggs. Feed intake was higher in Peshawari variety while, body weight and FCR/Kg egg mass showed non-significant differences. The birds of younger age showed significantly higher feed intake, egg mass, egg production, and better FCR/dozen eggs, while, egg weight and FCR/kg egg mass were not affected by age. Older birds showed significantly higher body weight.</p> Aseel Chicken, Production performance, Pre-moult, Post-moult, Variety Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=2014-JAPS-185
