Abstract:
A total of 300 day-old commercial broiler chicks were procured and randomly distributed into five treatments, each treatment had four replicates with ten chicks in each replicate. Growth trial of 6 weeks was conducted in a complete randomized design comprising five dietary treatment groups. The control group (T1) was offered maize- soybean meal based diet with sunflower oil. While, T2, T3, T4 and T5 were fed with linseed oil replacing sunflower oil of control group @ 25, 50, 75 and 100%, respectively. The body weight gain (g) and feed intake in different treatment groups during overall period of growth did not differed significantly (P<0.05) than the control group T1. Feed conversion ratio during overall periods was not affected due to replacement of sunflower oil with linseed oil up to 100%. The results showed that the mean value of Energy efficiency ratio and Protein efficiency ratio of different dietary treatments having linseed oil did not differ significantly upto 100% replacement with linseed oil with the control group. Protein efficiency ratio, Dry matter metabolizability percent and nitrogen retention values did not vary due to replacing of sunflower oil with linseed oil at various levels. Also gross energy metabolizability did not differed significantly in all dietary treatments upto 100% replacement with linseed oil.
