Investigating the Production Differences of Generations of Foreign Cows with Kandhari in Environmental Conditions of Afghanistan

Hamidullah Rahimi, Ghulam Rasoul Fazli, Sayed Alam Anwari

Crossbreeding is one of the most effective ways to improve production and increase resistance to the environmental conditions of cattle breeding. This study was conducted in 2020 as a questionnaire to determine the differences in production of Holstein cows, withBrowns wise and Jersey overweight calves, milk production, and lactation in the Afghan environmental condition. this study on 12 cows,from two crossbred breeds of cows, which 4 was a Holstein breed with Kandhari, 4breeds of cows was Kandhari with Brown Swise, and 4 anther breeds of cows were Kandhari withjersey, and the present study conducted in all three generations of F1 hybrids. Also, for this study 12 hybrids calf?s generation studied from individuals of four crossbred cows, calves from each generation under study were studied from the point of view of live birth weight at birth. The statistical population of the study consisted of livestock department, animal clinic, cattle breeding record, veterinarian and animal husbandry, including 100 persons selected randomly. Data has been analyzed through from Excel program. The results of the study indicate that calf birth weight improves significantly in the hybrid breeds, as a result of the calf's live birth weight Kandhari was 25 kg at the time of calving, before of crossbreeding. After cross With Holstein 35 kg, with BrownsSwise33 kg and with Jersey 26 kg, as the milk production of Kandhari cows was 1500 kg before crossbreeding, and after crossed with Holstein, browns swise and Jersey respectively were 3000, 2600 and 1850 kg. And the lactation of Kandhari generation was 183 days and cross-generations Modified Holstein, Browns swise, and Jersey were increased to respectively 270, 230 and 192 days, The results of this study show that the highest calf birth weight, milk production and lactation were respectively between hybrids of Holstein-Kandhari, Brownswiss-Kandhari and Jersey-Kandhari. While the Kandhari cows had lowest calf weight during the births, milk yields and lactation compared to the crossbred of anther generations under this study.
