Abstract:
India is a country of diversified agro climatic condition. Agriculture and livestock are the main occupation of over three fourth of the citizens. The present study was conducted on Genetic studies on calving interval and its influence on some important economic traits in crossbred cattle. The data for study were collected from history sheet records maintained at the Department of Animal Husbandry and Dairying, Sam Higginbottom University of Agriculture, Technology and Sciences Prayagraj, (211007) Uttar Pradesh Milk production is considered to be one of the most important economic traits in selection of dairy cows. Causes of variation in milk yield may be due to genetic, environmental and management factors. Calving interval refers to the period between the birth of a calf and the birth of the next calf. The duration of calving interval ranges from 360-450 days with an average of 405 days in cattle. The first lactation milk yield (kg) of 1/8 Jersey × 7/8 Red Sindhi crossbred cattle ranged from 1314.77 to 3217.59 Kg. The differences in the complete lactation milk yield of cows due to calving interval group were significant. The first lactation milk yield (kg) of 1/4 Jersey × 3/4 Red Sindhi crossbred cattle ranged from 1060.55 to 3375.1 Kg. The differences in the complete lactation milk yield of cows due to calving intervals group were non-significant. Calving interval has a great influence on complete lactation milk yield, 305 lactation milk yields. The 305days lactation milk yield (kg) of 1/8 Jersey × 7/8 Red Sindhi crossbred cattle ranged from 810.32 to 2089.05 Kg. The differences in the 305 days lactation milk yield of cows due to calving interval group were significant. The 305days lactation milk yield (kg) of 1/4 Jersey × 3/4 Red Sindhi crossbred cattle ranged from 914.67 to 2247.48 Kg. The differences in the 305 days lactation milk yield of cows due to Calving interval group were significant. It was concluded that the Calving interval 390-450 days has the highest complete lactation milk yield, 305 lactation milk yield. Shorter dry period was also observed in calving interval period of 360-450 days among the different crossbred Cows 1/8 jersey X 7/8 Red Sindhi, 1/4 jersey X 3/4 Red Sindhi.
