Influence of dietary energy levels and protein degradability ratios on reproductive performance and serum mineral profile in early lactating cows

Year: 2025

Type: article

Abstract: This study evaluated the effects of three total mixed rations (TMRs) with varying energy levels and RDP:RUP ratios on reproductive performance and mineral status in early lactating crossbred dairy cows over 90days. Twenty-one cows were randomly assigned to three isonitrogenous dietary treatments: G1 (60 TDN, RDP:RUP ratio 70:30), G2 (65 TDN, RDP:RUP ratio 70:30), and G3 (70 TDN, RDP:RUP ratio 60:40). Parameters assessed included days in milk at first artificial insemination, service period, pregnancy rate and serum mineral concentrations. While no significant differences were observed among the groups, the results indicated that all diets adequately supported reproductive performance and maintained mineral balance in early lactating crossbred cows.
