title: Dairy Heifer Development and Nutrition Management.
abstract: Heifer development depends on nutritional management decisions throughout all growing phases. Optimizing costs to raise heifers improves profitability of dairy farms. Feed costs for heifers make up 50% of heifer costs. Required growth rates depend on the desired age at first calving and estimated mature body weight. Intensive milk feeding improves calf growth and subsequent milk production. Prepubertal heifers should be fed for adequate gains to calve between 22 and 24 months of age. Controlling gains in pregnant heifers to limit fat deposition is possible using limit-feeding of a higher concentrate diet or using high-fiber forages to reduce diet energy.
