NORMS OF NECESSITY OF MEAT BREED PIGSAND CROSSES IN ENERGY AND DIGESTIBLE AMINO ACIDS
06.00.00 Agricultural sciences
DescriptionNorms of energy and amino acids for pigs worked out by factorial method are presented in the article. Norms of irreplaceable amino acids for growing pigs, pregnant and feeding swines, hogs are presented with an account of their real digestibility, that is positive moment in improvement of rated pig feeding.

NUTRITION AND HEALTH OF HIGH-PRODUCTIVE COWS
DescriptionIt this article, the situation in dairy practice with nutrition factors caused metabolic diseases such as ketosis, acidosis, lameness and a decline in fertility is shown. The article has the proposes on the nutrition of highly productive cows in transition period

Description
Application of a factorial method for determining the needs in metabolic protein and essential amino acids, helps to deepen knowledge on physiology of protein and amino acid supply and allow to improve the standards for dairy cows during the transition period; in insufficient of metabolic protein and essential amino acids increased coefficients of their transformation into net protein and absorptive amino acids as a result of mobilization of body of cows; with an optimal protein nutrition their transformation in net milk protein, lysine and methionine accordingly amounted to 0.67, 0,83 and 0,82. The most significant changes in the concentration of methionine, proline, glutamate, glutamine, glycine were observed in cows before calving and immediately after birth, stabilization of their level starts with a 24 lactation day, that is connected with the peculiarities of the feeding behavior of the cows and the gradual intensification of the processes of metabolism and milk production. To control the status of protein metabolism we have offered benchmarks compositions of free amino acids in cows’ blood plasma phases: 21-0 days before calving, 0-21 and 22-120 days after calving

EFFECT OF DRY BAKERY YEAST SACCHAROMYCES CEREVISIАE IN MILK COWS DIET
06.00.00 Agricultural sciences
DescriptionThe effect of dietary supplementation with dry bakery yeast culture Saccharomyces cerevisiae in high concentrate diet (F:C=47:53) on milk yeald and rumen fermentation were studied on two groups primiparous lactaiting cows (8 cows per group) and four ruminally cannulated nonlactaiting cows on diet F:C=25:75. Cows fed yeast during 67 days produced 1.24 kg/d and 1.66 kg/d natural and 4% fat corrected milk respectively more, than control cows. Milk protein and fat percentages were also higher. On diet with yeast ruminal concentration of lactate was lower and butirate+propionate was higher. The yeast incrised rumen pH, decreased NH3 in rumen and urea in blood, decreased viscosity of rumen fluid

06.00.00 Agricultural sciences
DescriptionAn experiment was conducted to examine the effect of fatty acid concentrate (FAC), as a new source of energy and carnitine on performance, physiological condition and meat quality of broiler chickens. In experiment there were four groups of 80 chickens of cross Hubbard each (males: females=40:40) in age period 0-41 days. 1 group (control) received in during the periods 0-14, 15-28 and 29-41days, sunflower oil (SO) respectively 5.34%, 5.50%, and 6.10%, group 2 received the same amounts of FAC instead SO, 3 group - mixture SO:FAC (50:50), 4 group -FAC + 0,25% carnitine. Final body weight: 1 group = 2574±29 g, 2 group FAC= 2553±27 g 3 group SO + FAC = 2531±34 g., 4 group FAC+0,25 carnitine = 2520±34 g. Feed conversion, digestibility of nutrients, blood hematology and biochemistry, the condition of organs, meat quality and cutting of carcass of chickens on FAC had no any differences from the same signs in chicks on SO. Carnitine had a positive effect on chicken growth only in the period 0-14 and less 15-28 days; in the period 29-41 days daily gain was below, than that in 1-3 groups. Canitine reduced the content of liver fat. Outcome: FAC is a satisfactory source of energy, comparable with vegetable oils. The price of FAC is 30% lower in comparison with sunflower oil and soybean oils, therefore its use in broiler poultry farming instead of vegetable oils will be of great economic importance
