Studies on Growth Performance of Improved Varieties of Chicken
Abstract:
The present investigation was carried out to study growth traits in improved varieties of chicken. Six different varieties namely CARI Shyama, Vanaraja, Kalinga Brown, Black Rock, Caribro Dhanraja and Kuroiler used in Chhattisgarh for backyard poultry were studied. The growth parameters studied were body weight, average daily gain, and average weekly gain up to 10 weeks of age. Significantly (P<0.01)) higher growth rates in males compared to females were recorded. The highest rate of growth was recorded for Caribro Dhanraja. The overall mean values for 10 weeks body weight were observed to be 1259.48±30.00, 1393.27±35.52, 871.98±25.24, 1366.91±30.96, 1823.47±33.74 and 1219.62±29.50g for CARI Shyama, Vanaraja, Kalinga Brown, Black Rock, Caribro Dhanraja and Kuroiler, respectively. Variety and age significantly affected the feed conversion ratio. The feed conversion ratios were observed to be 2.77, 2.55, 2.76, 2.50, 1.96 and 2.45 for CARI Shyama, Vanaraja, Kalinga Brown, Black Rock, Caribro Dhanraja and Kuroiler, respectively. Significant (P<0.01) effect of variety on shank length and keel bone length was observed. Sex also significantly (p<0.05) affected the shank length in present study. There was significant effect of variety on the growth performance of chicken.
