The article reviews the results of the study of influence of treatment of Saperavi vines with growth promoters (Immunotsitofit, Krezatcina and HB-101ECO) on its productivity and quality in the Anapо-Taman zone of the Krasnodar region
The key stage of clonal micropropagation, the micropropagation sensu stricto, affords to increase the propagation index for plants, especially perennials. In this study, we consider ways to optimize clonal micropropagation of remontant raspberry cultivars. It is found that microsprout regeneration rate is 78,5–96,0 % on the multiplication s. str. stage. The most multipurpose nutrient medium is selected with containing 0,5 mg/l both of BAP and GK. When one uses this medium, regeneration rate runs 79,0–94,0% depending on genotype with sprout high running 24,8–32,7 mm and sprout number – 1,2–2,2 per node. The optimal duration of growing cycle is 30 days with the propagation index within 6,6–7,8, depending of genotype
The author has studied the efficiency of diets with NATUPHOS 5000 enzyme preparation. Adding the enzyme preparation into the mixed fodder for chicken broilers favors increase of live weight by 4,5 % and average daily weight gain by 6,1 %
An 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
The author has studied the efficiency of diets with
kiselgura. Introduction of the kiselgura into the mixed
fodder for chicken-broilers favors increasing of live
weight by 4.8 % and average daily weight gain by 5.0%
The article presents the data of the effect of processing soybean seeds with exogenous amino acids and its effect on photosynthetic activity of soy
The 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
The article presents the results of researching into the effect of drip irrigation on build-up of soil salinity using water with high salt content and the dynamics of changes during winter period under atmospheric precipitation. It was established that at the end of irrigation season zones with high salt content formed on the soil surface under drip irrigation using sodium sulfate water, among these salts gypsum was presented. In spring time the increasing of sodium sulfate content was found that indicates the exchange reaction with soil exchange complex passed as well as the insufficient salt leaching occurred during the winter period. In spring time the upper soil layer characterized with alkaline type of soil salinization
