Study on Productive and Reproductive Characteristics of Pure and Crossbreed Red Chittagong Cattle at Govt. Dairy and Cattle Breed Development Farm, Hathazari, Chattogram

Abstract

The present study was accomplished at Govt. Dairy and Cattle Breed Development Farm, Hathazari, Chattogram from 20th March 2023 to 11th April 2023. The study aimed to know the general information about pure RCC and mixed breed RCC, common feeding practices along with production and reproduction performance. In this study, about 20 pure and 20 crossbreed RCC were included. The data were collected from the caretaker, milkman, AI technician and farm Deputy Director through a conducted questionnaire. The data demonstrated that pure bloodline RCC heritability is 100% where crossbreed RCC bloodline vary from 50 to 87.5%.Among individual nutrition, supplying maize in ration of RCC at high rate, pure RCC milk is slightly sweetish and yellowish than normal milk of crossbreed RCC. Also average body length of pure RCC (109.283 cm) is shorter than crossbreed RCC (119.771cm). Beside these, pure RCC mature female (avg. 196.924 kg) have lower body wt. than crossbreed RCC female (avg. 248.853 kg). Also, pure RCC female have shorter gestation period (280.4±8.911 days), lactation length (302.15±11.847 days), post-partum heat (92.20±6.542 days) than crossbreed RCC female gestation period (280.95±10.144 days), lactation length (298.1±9.781 days), post-partum heat (108.05±24.237 days). Finally, it can be said that developing pure bloodline RCC is as great as for using like dairy cattle than crossbreed RCC and to improve indigenous or crossbreed cattle bloodline using like RCC. It is better to use 100% bloodline of RCC for developing this RCC as a dairy and prolific breed worldwide and for fulfilling meat and milk demand in prospect of Bangladesh and developing country.
