Large fluctuations in milk and supplemental feed prices create anxiety and uncertainties. Profit margin may shrink rapidly when milk price goes down and supplemental feed prices go up. Thus, it is important that correct decisions are made to maximize return on supplemental feed expenses.

To examine the effect of carbohydrate and/or protein supplements on the hormonal state of the body after weight-training exercise, nine experienced male weight lifters were given water (Control) or an isocaloric carbohydrate (CHO; 1.5 g/kg body wt), protein (PRO; 1.38 g/kg body wt), or carbohydrate-protein (CHO/PRO; 1.06 g carbohydrate/kg body wt and 0.41 g protein/kg) supplement immediately an...

Protein undernutrition is known to play an important role in the pathogenesis of osteoporotic fracture in elderly. The mechanisms underlying the bone loss in protein undernutrition appeared to be related to an uncoupling between increased bone resorption and bone formation. This was associated with decreased plasma IGF-I levels, with anoestrus and decreased muscle mass. Reversibility of protein...

In our early experimental inquiries1 on the growth of swine we soon learned that restriction to any one grain and its protein concentrate or a mixture of grains and seed protein concentrates would lead to nutritional failure. Growth would cease and evidences of serious malnutrition appear. It was found that certain supplements to the grains must be made if physiological soundness was to be main...
