The yield of dry matter (DM) in a mature wheat crop can equal that obtained from three cuts of grass. Ensiled mature whole crop wheat is however characterised by a lower digestibility and lower crude protein concentration than good quality grass silage. Addition of urea at ensiling has been shown to increase the digestibility and the non-protein nitrogen concentration of whole crop wheat silage. The objectives of this study were to determine (i) the effect of urea-treatment on the in vivo digestibility of wheat of relatively high moisture concentration and (ii) the effects of the provision of a rapidly fermentable carbohydrate supplement on nitrogen metabolism in steers fed these silages.

Numerous studies have shown that ingesting carbohydrate in the form of a drink can improve exercise performance by maintaining blood glucose levels and sparing endogenous glycogen stores. The effectiveness of carbohydrate gels or jellybeans in improving endurance performance has not been examined. On 4 separate days and 1–2 hr after a standardized meal, 16 male (8; 35.8 ± 2.5 yr) and female (8; 32.4 ± 2.4 yr) athletes cycled at 75% VO2peak for 80 min followed by a 10-km time trial. Participants consumed isocaloric (0.6 g of carbohydrate per kg per hour) amounts of randomly assigned sports beans, sports drink, gel, or water only, before, during, and after exercise. Blood glucose concentrations were similar at rest between treatments and decreased significantly during exercise with the water trial only. Blood glucose concentrations for all carbohydrate supplements were significantly, p < .05, higher than water during the 80-min exercise bout and during the time trial (5.7 ± 0.2 mmol/L for sports beans, 5.6 ± 0.2 mmol/L for sports drink, 5.7 ± 0.3 mmol/L for gel, and 4.6 ± 0.3 mmol/L for water). There were no significant differences in blood glucose between carbohydrate treatments. The 10-km time trials using all 3 carbohydrate treatments were significantly faster (17.2 ± 0.6 min for sports beans, 17.3 ± 0.6 min for sports drink, and 17.3 ± 0.6 min for gel) than water (17.8 ± 0.7 min). All carbohydrate-supplement types were equally effective in maintaining blood glucose levels during exercise and improving exercise performance compared with water only.

Due to the deficiency of certain nutrients in the diet of athletes and many categories of the population, there is a need for more targeted use of meat and meat products and the inclusion of traditional foods with physiologically functional ingredients to replenish the body with appropriate nutrients. The article presents the development of technologies for new types of meat products using the protein-carbohydrate supplement “Gainer” – a concentrate of nutrients. Gainer protein-carbohydrate supplement is a powdered mixture of white, gray, yellow or other color with chocolate, vanilla, strawberry flavor or without taste, intended for gaining muscle mass. The protein in this mixture is presented in the form of a protein obtained from milk, carbohydrates are represented by starch obtained from corn.During the studies, the effect on the solubility of the additive was determined, the temperature of sodium chloride was found to pass into a solution of 1.08 to 1.28 mg/ml of protein, which is 42.9 and 48 % according to their total content, which is determined at plus 20 °C. As the temperature increases, the solubility of the proteins of the protein mixture increased, reaches maximum values at a temperature of about plus 50 °C and is 127 % of the initial level at plus 4 °C. A further increase in temperature leads to a decrease in the indicator and at plus 85 °C its value is 37.8 % of the initial level. In the presence of sodium chloride, the solubility of the protein mixture is significantly increased. The most noticeable changes were observed at a NaCl concentration of up to 1 % by weight of the solution. With increasing concentration of NaCl in the system, the solubility of proteins also increases, but less intensely. Studies of the ability to interact with fat have shown high absorbent, binding, emulsifying properties of the protein mixture of Gainer. The stability of emulsions is about 60 %, which corresponds to the emulsifying ability of collagen proteins. A study was also conducted to determine the amount of protein-carbohydrate supplement in cooked sausages. The study showed that the introduction of hydrated milk-protein mixture of protein and carbohydrate additives in the composition of minced meat leads to an increase in the mass fraction of moisture, decrease in the mass fraction of protein and fat in proportion to the increase in the level of raw meat in minced meat.

Muscle glycogen is an essential fuel for prolonged intense exercise, and therefore it is important that the glycogen stores be copious for competition and strenuous training regimens. While early research focused on means of increasing the muscle glycogen stores in preparation for competition and its day-to-day replenishment, recent research has focused on the most effective means of promoting its replenishment during the early hours of recovery. It has been observed that muscle glycogen synthesis is twice as rapid if carbohydrate is consumed immediately after exercise as opposed to waiting several hours, and that a rapid rate of synthesis can be maintained if carbohydrate is consumed on a regular basis. For example, supplementing at 30-min intervals at a rate of 1.2 to 1.5 g CHO kg-1 body wt h-1 appears to maximize synthesis for a period of 4- to 5-h post exercise. If a lighter carbohydrate supplement is desired, however, glycogen synthesis can be enhanced with the addition of protein and certain amino acids. Furthermore, the combination of carbohydrate and protein has the added benefit of stimulating amino acid transport, protein synthesis and muscle tissue repair. Research suggests that aerobic peiformance following recovery is related to the degree of muscle glycogen replenishment.
