Abstract

The invention relates to agriculture, in particular to the feeding of ruminant animals. The invention relates to agriculture, mainly to the composition of the feed mixtures for ruminants. The purpose of the invention is to increase the digestibility of the feed by reducing the intensity of ammonia-forming processes in the rumen, as well as increasing the U-tails, and can be used in the preparation of rations for growing and fattening livestock. The purpose of the invention is to increase the digestibility of the feed by reducing the intensity of ammonia formation processes in the rumen, as well as increasing the gain in live weight, reducing the cost of the resulting products of ruminants. of the men. In the concentrated mixture for growing and fattening cattle, containing, wt.%: Monocalcium phosphate 1.0 to 1.4; sodium sulfate 0.7-0.9; salt 0.9-1.1 and a cereal grain mixture (filler), methylenediamine (m-2M) 4.0-4.6 is added as an additional source of nitrogen. The use of methylene diurea makes it possible to reduce by 65-70% the intensity of ammonia formation in the rumen, increase by 4.28-8.75% the increase in live weight, reduce by 2.22-9.32% the cost of feed units per 1 kg of increase and -9.24% protein, as well as 2.72 rubles.

Description

of the scar for 6 hours. The intensity of emiecogenesis in the incubation medium during the hydrolysis of urea (M) and methyl methyndiourea (m-2M) was compared. Fixation of ammonia concentration determinations in comparable variants was carried out after each hour of incubation.

In vivo experiments were carried out on bodies (gobies analogs older than six months of age with an initial live weight of 180–190 kg) for 79 days. In each compared example, there were eight heads. The feed mixture for animals of the 1st example (control) was 30% deficient in nitrogen protein. In the feed for animals of the 2nd example (prototype), 30% of the nitrogen deficiency of the protein is replenished with urea nitrogen (M). and for the 3-5th examples (according to the proposed solution), the indicated protein deficiency is replenished with methylediurea (m-2M),

The curve reflecting the dynamics of changes in the level of ammonia formation is much lower. Compared with the prototype, at the maximum points of development of the intensity of the ammonia-forming process, the level of ammonia in the scar environment is lower by 65-70%. Consequently, the decay rate of methylenediamine (m-2M), in the scar environment is 65-70% lower than urea (M). This coincides in the data obtained under the conditions .In viyo (Table 1). from which it is clearly seen that the level of ammonia in the rumen of the bodies in the first hour after the start of feeding decreases 1.87 times (30.57: 16.31 mg%). In parallel with this, the level of urea (27.5: 21.7 mg%) in the blood decreases by 1.27 times, which indicates a significant decrease in ammonia formation in the rumen and more efficient absorption of non-protein nitrogen in the body when feeding methylenedibrea instead of urea . This conclusion is confirmed by the data in Table. 2. They show that, in comparison with the prototype, the increase in live weight is 4.28–8.75% more, the cost of feed units per 1 kg increase is 2.22–9.32% lower, and protein - 7.14–9 , 24%, and ultimately lower and the cost of 1 kg of increase in live weight by an average of 2.72 rubles.

Thus, a significant decrease in the intensity of ammonia formation in the rumen when feeding a feed mixture containing m -2M causes a reduction in the loss of endogenous energy to neutralize and remove excess ammonia from the body. This leads to more efficient uptake of nitrogen and an increase in the productivity of ruminants without first training them to a nonprotein source of nitrogen and without additional input of easily digestible energy into the diet. Such biochemical indicators as the concentration of total sugar, glucose, pentose, lactate, ketone bodies. beta-butyric acid in the blood / is within the physiological norm and testifies to the harmlessness of feeding comparable nitrogen sources.
