Investigating non-genetic factors impacting first lactation milk yield in Mehsana buffaloes

Buffaloes are known as the backbone of dairy industry in India by contributing about half of milk production. Milk production, a complex trait, is influenced by various non-genetic factors. This study investigated the impact of non-genetic factors on the first lactation performance of Mehsana buffaloes, focusing on their 305-day milk yield (305DMY). The dataset, comprising 23,608 records, was obtained from the National Dairy Development Board (NDDB), Anand, recorded through the Indian Network for Animal Productivity and Health (INAPH). Age at first calving, year of calving, month of calving, and union (milk co-operative society) were considered as non-genetic factors. Statistical analysis, including Least Squares Analysis and Duncan’s Multiple Range Test, revealed that all factors had a highly significant (P < 0.01) influence on 305DMY. These findings contribute valuable insights into dairy herd management strategies, aiding dairy farmers, policymakers, and researchers to optimize milk production and improve the overall productivity of Mehsana buffaloes.
