Abstract
The present investigation entitled “Studies on Supplementation of Linseed (Linum usitatissimum ) oil in the feed of Giriraja Poultry Birds.” was carried out to assess the effect of feeding Linseed oil on Live body weights, Body weights gain, weekly Feed consumption, Cumulative feed consumption, Feed conversion ratio (FCR), Dressing percentage, fatty acid profile of breast and thigh muscle, Mortality percentage, Sensory quality of breast and thigh meat and Economics of Giriraja poultry birds production.
150 day old straight run commercial Giriraja chicks were procured from Government regional hatchery Nagpur. They were randomly and equally distributed into five treatment groups T1, T2, T3, T4, and T5 with 30 numbers of chicks in each group.
Linseed oil were added in experimental ration at different levels. The dietary treatments consisted of one basal T1 (control), supplemented with T2 (2% Linseed oil) T3, (3% Linseed oil), T4, (4% Linseed oil), and T5 (5% Linseed oil).
The average live body weight at seventh weeks of age was 1271.60, 1343.40, 1478.73, 1370.23 and 1253.03 (g/birds) in T1, T2, T3, T4, and T5 treatments groups respectively.
The corresponding weekly body weights gain at the end of seven weeks of age were 312.97, 339.83, 372.33, 325.50 and 318.53 (g/birds) in T1 to T5 treatment groups, respectively.
The average total weekly feed consumption g/birds during the experimental period at end of seventh week was recorded as 677.0, 682.8, 669.7, 673.9, and 672.4 for T1, T2, T3, T4, and T5 treatment groups respectively.
The cumulative feed consumption at seventh weeks of age were 2650.9, 2676.9, 2648.4, 2655.0 and 2614.8 (g/birds) in T1, T2, T3, T4 and T5 treatment groups respectively.
The Feed conversion ratio of various groups at seventh week in T1, T2, T3, T4 and T5 were 2.11, 1.98, 1.79, 1.94 and 2.09 respectively.
The average dressing percentage among the different treatment group varied between 70.52 to 69.11 percent. Numerically higher dressing percentage was recorded in treatment T3 (74.51).
The fatty acid profile of breast and thigh muscle recorded in per cent all treatment groups were significant. However the highest value breast muscle in of total n-3 in T5 (11.93), T4 (8.45) and T3 (6.14) lowest value T2 (2.55) and T1 (0.97) and thigh muscle are highest value of total n-3 in T5 (12.68), T4 (9.30) and T3 (6.39) lowest value T2 (2.80) and T1 (1.22).
The overall mortality in Giriraja poultry birds of various groups during the experimental period was zero.
The mean score of sensory quality of breast and thigh meat have all treatment groups were non significant.T3 group was superior in breast meat (7.6), (7.7), (7.9), (7.9) and (8.0) and thigh meat have (7.8), (8.0), (7.5), (7.8) and (7.8) under treatments groupsT1, T2, T3, T4, and T5, respectively.
The net profit per bird was highest in T3 (Rs.133.5) followed by T2 (112.26), T1 (109.22), T4 (106.42) and lowest in T5 (Rs.78.15). It was observed that treatments T3 and T2 were the most beneficial feeding of linseed oil on net return in Giriraja poultry birds as compared to T5 group.
