335 Metabolizable protein requirement of lightweight beef calves

Performance of Beef Calves

These results support the earlier findings by Dr. Bill Kunkle and his research involving limitcreep supplements based on cottonseed meal and salt mixtures. Calf performance responses, as measured by the added gain realized by creep supplementation, are highly variable and cannot always be described by amounts of creep feed consumed. This variability has large and direct impacts on the cost effe...

Early weaning beef calves.

Early weaning is a management practice that reduces grazing pressure on pastures by decreasing the nutrient requirements of cows. Calves that are weaned early are relatively efficient at converting feed to gain, and can weigh as much, or more than, calves allowed to remain with their dams until a conventional weaning age is reached. Balanced diets with excellent physical, chemical, and palatabi...

Supplementation to meet metabolizable protein requirements of primiparous beef heifers: II. Pregnancy and economics.

Metabolizable protein (MP) requirements of spring calving heifers increase over the winter due to advancing gestation. The MP content of grazed winter forage is low, which may result in an MP deficiency. The objective was to compare the response of supplementing pregnant yearling heifers to meet MP requirements versus conventional CP supplementation. In 1997-98 and in 1998-99, pregnant, March-c...

Brain Regulation of Growth in Beef Calves

Small peptide hormones produced in the lower part of the brain (hypothalamus) regulate episodic and basal secretion of hormones from the anterior pituitary gland that affect metabolism and growth in cattle. This study focused on long-term growth in young calves subjected to hypophysectomy (HYPOX), hypophyseal stalk transection (HST), and sham operation control (SOC). Crossbred (Hereford x Aberd...
