Effect of Nutrient Improvement and Mineral Premix Supplementation on Weight, Average Daily Gain, and Metabolite Profile of Repeat Breeder Cows

Abstract Nutrient overload, deficiency, or imbalance are fundamental issues that frequently arises in breeder cows. Malnutrition cattle can cause delayed puberty, an increased risk of pregnancy failure, and infertility. This study aimed to determine the effect nutrient improvement mineral premix supplementation on body weight, average daily gain, blood metabolite profile repeat cattle. Sixteen Simmental Cross aged 4 5 years (calved at least once) with S/C weight 400 kg were used. The feed provided was forage, Profeed® concentrate, High Quality Feed Supplement (HQFS) premix. initiated by selecting smallholder farmers. selected reared for three months research cage a predetermined each group. During period, four weighings carried out Blood samples taken testing profile; beginning end study. collected then analyzed laboratory, resulting data variance using independent-t-test paired t-test. results showed addition 0.5% had no significant (P > 0.05) gain. In profile, nutrition (P<0.05) glucose levels (H-0 H-71). It be concluded has profiles. Repeat farmers have low levels, so improving (quality quantity) is matter concern support pregnancy.
