Description

The invention relates to livestock, in particular to poultry, and can be used in the cultivation of broiler chickens.

The purpose of the invention is the improvement of feed quality while increasing the gain in live weight of broiler chickens.

The goal is achieved by the fact that sodium thiosulfate is introduced into the main diet for broilers as a neutralizer of toxicity of nitrites, which is mixed with compound feed before feeding. During the experiment, sodium thiosulfate was added to the diet in the amount of 0.05-0.25% of the dry matter of the feed. However, the experiment showed that the introduction of sodium thiosulfate in an amount of 0.05% of the dry matter of the feed mixture is not sufficient to completely neutralize nitrites, and increasing it to 0.25% practically does not affect the results of cultivation, therefore, the optimal dose of adding sodium thiosulfate to the feed mixture was chosen 0 , 1-0.2% of dry matter.

Example. For the experiment, 8 groups of 50 heads of chickens were formed:, w Lyat broilers of the cross. Competitor in principle of I / cip counterparts. The feed mixture was composed separately for the first growing period | C, (1-4 weeks) and for the second - (5-7 weeks) according to the norms of the All-Union Agricultural Institute (1985).

The first (control) group was fed the main diet (RR). In the second experimental group, sodium thiosulfate was introduced into the feed mixture in an amount of 0.1% of the dry matter feed mixture, in the 3rd group, potassium nitrite was introduced in an amount of 0.1% of the dry matter, in the 4th, 5th, 6th, 7th and 8th groups were added 0.1 % potassium nitrite, as well as sodium thiosulfate, respectively 0.05: 0.1; 0.15; 0.2 and 0.25% of dry matter. The additives were mixed ι with a certain amount of feed, · after which they were transferred to the feed mixture and thoroughly mixed. Feed mixture add- ^! they were fed into the feeders as it was eaten 2-3 times a day. ί

The results of the experiment (see table) showed that when the nitrite content in the feed mixture of broiler chickens in quantity

0.1 g per 100 g of feed mixture showed a decrease in their belly weight compared to the control by 7.9%, an increase in feed costs by

The introduction of sodium thiosulfate into the feed mixture containing nitrites increased the mass of broilers by 2.8-4.3%. reduction of feed costs per 1 kg of live weight gain of 5 weight by 1.7-7.6% compared with the control, in relation to the third group receiving nitrites, an increase in the weight of broilers was 10.7-12.2%, and a decrease in feed costs -17.7-23.6%. 10

Using the proposed method for preparing feed for broiler chickens allows her / p’s to use * the effect of nitrites on the animal’s body and to obtain higher live weight gain and lower feed cost per 1 kg of growth compared to the prototype.
