In this work, the influence of "Topinambur" and "VitaSelen" nutrition additives on productivity of pigs and food meat value is presented, as well as on morphological and chemical composition of blood
Winter wheat is very demanding on the nutrient regime of the soil. Like many winter crops, it consumes the nutrients unevenly distributed during the vegetation period, which must be considered when making them. Modern varieties of winter wheat are very demanding to soil fertility. For the formation of 4,0-4,5 t/ha requires about 140 kg of nitrogen, 50 kg phosphorus and 120 kg potassium. Therefore, without the use of fertilizers, it is not possible to obtain such a crop with high grain quality. In addition, in the cultivation of winter wheat in the high and intensive technologies simply need using large amounts of fertilizer to compensate for the removal of nutrients. This is especially important when having partial or complete reduction of application of organic fertilizers. Therefore, we consider the possibility and the results of studies using different doses, combinations and types of fertilizers in technology of winter wheat cultivation. Experimental studies were carried out in the conditions of insufficient and unstable moistening of southern zone of Rostov region, on experimental fields of the federal state scientific institution «ASС «Donskoy». For research, we have chosen the most common varieties of winter wheat (Tanais, Granite, Axinite, Terra, Donskoy prostor, Motto) and various combinations and combinations of mineral and organic fertilizers. The experiments were conducted on two predecessors: couples and peas. As the controllable parameters we had the productivity and quality of winter wheat. We have found a positive impact of the in-change of fertilizer on the studied parameters with a share of the variance of 96% and a high degree of correlation of 0,98. The marked increase in the productivity of winter wheat is up to 22% when using different versions of the experiment. We have identified rational combination doses of mineral and organic nutrition for predecessors: peas N40P60K40+2N30 and vapor – manure 40t/ha+2Р60+2N30
The article describes the efficiency of a feed additive
called "Tetra+" during chronic mycotoxicoses of pigs.
The purpose of carrying out series of experiments on
sows was to determine the therapeutic and
prophylactic effectiveness of innovative feed additive
"Tetra+" during combined chronic mycotoxicosis in
pigs and to study the influence of feed additive on the
growth, weight, preservation and overall resistance of
sows. The results of the experiments revealed that a
feed additive "Tetra+" has had a positive impact on
large-fruited of pigs; it can also be concluded that the
feed additive "Tetra+" has a positive effect on the
metabolism of proteins, carbohydrates and has
antitoxic properties
In the article the results of the influence of various types of hybrids and their variants of sterilization on efficiency of sugar beets are shown, and also their economic estimation is given
In the article, we have revealed the efficiency of sown using of fertilizers, the methods and the doses of additional fertilizing on different maize subspecies growing on the leached black soil of Northern Ciscaucasia which are based on studies in central part of the Kras-nodar region in 2008-2010. We have also given the scientifically-based references of increasing productiv-ity of maize
In the article, the estimation of efficiency of selection on high tillering is given at various planting density. For the analysis used plants of variety Lampo with high tillering ability and varieties the Virazh and Ko-mandor - with weak tillering ability, and hybrid popu-lations F3 from their crossing, selected on traits high and low tillering from F2. Plants ¬ placed on plots in three variants: 2×15, 15×15, 30×30 cm. It is estab-lished that distinctions on tillering between “+” and “–” selection in following generation remain, though the value of given trait at hybrid plants decrease. Selection of highly tillering forms at usual density (2×15 cm) has shown high efficiency, because the tillering is caused by more influence of genetic factors, than environment in the given variant
The article results the study of irrigation regime im-pact on water consumption and yield of grain sor-ghum. It is established that optimal conditions for growth and development are created by maintaining soil moisture content in a soil layer of 0.6 m higher than 80 % of field capacity (FC), where the grain yield reaches 14 t/ha and the best indices of profit and cost-effectiveness are obtained
Ferrourtikavit is a biologically active additive (BAA)
derived from common nettle supplemented with micro
nutrient elements (titanium, vanadium, molybdenum,
zinc, copper, iron, tin, chromium, manganese, barium).
Ferrourtikavit is manufactured from local vegetable
raw materials, however its application in feeding dairy
cows is not sufficiently studied. Therefore, the
application of the BAA ferrourtikavit in animal
feeding with a view to increase milk production is
relevant. The aim of the research conducted is to
investigate the impact of the BAA ferrourtikavit on the
overall nutritional value of animal diet and reduction
of food consumption. The experiment was conducted
on four groups of black-motley breed dairy cows.
Formation of the experimental groups (15 animals per
each group) was performed on the third lactation,
taking into account age, productivity during the
previous lactation, breed characteristics, live weight.
The main diet consisted of hay, haylage, succulent
fodder, concentrates. Additionally to basic diet the 2nd
,
3
rd and 4th experimental groups obtained the BAA
ferrourtikavit at the doses of 0,25, 0,50 and 0,75 mg/kg
of live weight, respectively. It has been established
that the animals from the experimental groups (2nd, 3rd
and 4th) consumed 43,9-51,3 energetic feed units less,
439,4-513,5 MJ metabolic energy less, 56,4 – 62,0 kg
dry matter less, 1,1 – 1,6 kg digestible protein less.
The lowest feed consumption was noted among the
animals from the 3rd experimental group, in the basic
diet of which the BAA ferrourtikavit in an amount of
0,50 mg/kg of live weight was introduced. The research conducted established, that application of the
biologically active additive ferrourtikavit in the diet of
lactating cows at the dose of 0,5 mg/kg of live weight
led to the highest milk yields 4678±45,17 kg. In the
experienced groups, increase in milk yields, decrease
in concentrates' utilization as well as costs of 1 kg milk
as compared to the control group were registered
