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 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 %
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 article presents the results of the studies of the use
of "Selenium-Vita" bioactive feed additive, containing organic forms of iodine and selenium, in the rations of lactating cows of Black-motley breed of Danish origin; positive influence of the tested drug on milk production and milk quality is revealed
The results of studies of the effect of different types of formation to the content of pigments in the leaves of apple trees in the central zone of Horticulture Kuban Krasnodar region. It is determined, that the content of chlorophyll «a» and «b» in the leaves is seasonal and depends on the biology class. The highest amount of chlorophyll in the leaves of apple in the autumn varieties (Prima, Gala) cultivars has been observed in August, in the winter varieties (Reinette Simirenko, Florine) - in September
This article presents results of trials of feed additives
called "Yoddar-Zn" and "Glimalask-Vet" to improve
quality characteristic of meat of beef cattle. It was
established that the most efficiency of these additives
was achieved when used in complex. The carcasses of
calves, which were consuming a complex of additives
"Yoddar-Zn” and “Glimalask-Vet” (I c.), contained
meat of the highest sort more than control by 6.48 kg,
the animals which consumed only "Yoddar-Zn” (II c.)
- 3.50 kg, the first-sort - at 15.19 and 7.86 kg. In
experimental groups of calves there were observed
more intense integral characteristics of meat color. The
flesh of carcasses from the calves of experimental
groups, the fat was higher than control, 0.13 and
0.07%, protein - by 1.79 and 0.97%. Animals
experimental groups synthesized more protein at 5.45
kg, or 13.70%, and 2.62 kg, or 6.59%, energy - to
304.3 MJ, or 18.17%, and 146.8 MJ, or 8.77%. Meat
of experimental animals, contained more essential
amino acids. Protein meat quality indicator was higher
than control, 0.73 and 0.28, amino acid index - by 0.17
and 0.04. The meat from calves of experimental group
had a higher culinary and technological parameters,
optimal fractional composition of muscle protein and
lipid composition of adipose tissue, better digestibility
The results of the experiment to study the influence of aromatic additive “Caramel-Vanilla” at the killing indicators of pigs of large white breed are presented in this article. It is established that the cultivation and a fattening of pigs when adding this aromatic additive to animal feed is an effective technique. The use of aromatic additives in rhythm input: 10 days with the addition of 10 days without it until the end of fattening positive impact on feed intake, growth, and the payment of his live weight gain of pigs. The live weight of animals for the period of experiment (123 days) increased by 8.6 % compared with the control
