The purpose of present investigation was to investigate to dietary supplementation of Black Cumin seed powder on their growth performance of Giriraja poultry birds and cost of production.The present investigation entitled “Effect of dietary supplementation of Black cumin (Nizella sativa) seed powder on growth performance of Giriraja poultry birds” was carried out to assess the effect of Black cumin seed powder on body weight, feed consumption, feed conversion efficiency (FCR), dressing percentage and economics of Giriraja poultry bird’s production. One hundred fifty chicks of day old Giriraja breed were procured from Govt Regional Hatchery, Nagpur (Maharashtra). They were randomly and equally distributed into five treatment groups T1, T2, T3, T4, and T5 with 30 numbers of chicks in each group. Black cumin seed powder was added in experimental ration at different levels. The dietary treatments consisted of one basal control (T1), supplemented with 1.0 % Black cumin seed powder (T2), 1.5 % Black cumin seed powder (T3), 1.75 % Black cumin seed Powder (T4), and 2.0 % Black cumin seed powder (T5). The corresponding average live body weights at the end of seven weeks of age were 1113.17, 1230.57, 1329.73, 1172.50 and 1104.03 gms, in T1, T2, T3, T4 &T5 treatment groups, respectively. The average weekly body weight gains at 7th week of age were 209.97, 189.50, 228.43, 183.07 and 169.13 gms. In T1, T2, T3, T4, and T5 treatments, respectively. The weekly feed consumption gram/bird during the experimental period at the end of seventh week were recorded as 717.8, 712.0, 704.7, 708.9 and 707.4. for T1, T2, T3, T4, and T5 treatments groups, respectively. The cumulative feed consumption at seventh week of age were recorded as 2686.9, 2660.9, 2658.4, 2650.0 and 2624.8 gms for T1, T2, T3, T4, and T5 treatments, respectively. The feed conversion efficiency g/birds at 7th.week of age were recorded as 2.44, 1.85, 1.72, 2.20 and 2.41 gms for T1, T2, T3, T4, and T5 treatments, respectively. The average dressing percentage among the different treatment group varied between 68.14 to 72.14 %. Numerically higher dressing percentage was recorded in treatment T3 (72.14). The net profit per bird was highest in T3 (Rs. 81.8) followed by T2 (Rs. 63.56), T1 (Rs. 52.3), T4 (Rs. 41.97) and T5 (Rs. 25.43) the result therefore concludes that supplementation of 1.5 % Black cumin seed powder was beneficial to improve growth, feed efficiency, net profit and immune system of birds.EnglishThesis
