A study of the effectiveness of the use of feed additive Liaform in relation to its effect on the growth and development of broiler chickens. For research, 2 groups of broiler chickens of 55 heads (control and experimental) from 8 days of age were formed on the principle of analogues. Feeding of the control group was carried out with standard complete feed. Feeding of the experimental group was carried out with standard complete feed, in which the feed additive Liaform was added at the rate of 2 g / kg. During the experiment, the general condition of the bird, the safety of the bird, zootechnical and hematological parameters were monitored. It is established that the studied feed additive has a positive effect on the productivity of broiler chickens, improves feed absorption. As a result of the use of feed additive Liaform live weight of broiler chickens in the experimental group was 4.3 % higher compared to the control. The average daily gain of chickens in the experimental group exceeded this figure of chickens in the control group by 4,1 %. The use of feed additives helped to increase feed conversion. The use of Liaform feed increased the protein level in poultry meat

The poultry industry in Russia has significant prospects for the development of domestic production of eggs and poultry meat. Insufficient attention is paid to the practical application of enzyme drugs, although numerous studies have proven the effectiveness of these substances in feeding animals and poultry. The purpose of the research was to determine the feasibility and effectiveness of using the multi-enzyme drug Axtra XAP 101 produced by DuPont as part of compound feed for growing broiler chickens. A scientific and economic experiment has been carried out and various doses of the multi-enzyme drug Axtra XAP 101 have been experimentally studied as part of compound feed and the optimal dose in the amount of 7–9 % of the dry matter of the compound feed has been identified. Multi-enzyme drug Axtra XAP 101 influences on indices of meat productivity of broiler chickens. It has been found that this drug increases the average daily increase in live weight of broiler chickens, reduces feed conversion and has a positive effect on the livability of livestock. The highest value for livestock livability has been observed in the 3rd experimental group, where it was 97,67 %, which was by 0,32 % higher than in the control group, by 0,5 % higher than in the 1st experimental group and by 0,57 % higher than in the 2nd experimental group. The European productivity index was the highest in the 3rd experimental group and amounted to 412 points. This indicator was higher than in other groups: higher than the control group by 20 points, the 1st experimental group – by 12 points, the 2nd experimental group – by 5 points. Thus, the effect of using enzymes in wheat and barley diets is to increase and equalize the nutritional value of different varieties and batches of grain. Changing the location and mechanism of microbial fermentation as a result of adding an enzyme also has a positive effect on the health of poultry.

Poultry Farming

The intensifi cation of modern industrial poultry farming as the most progressive and dynamically developing branch of agriculture aimed at raising productivity and increasing production volumes, inevitably leads to numerous problems related to poultry health. One of the most common ways to solve this problem is to use antibacterial drugs. The results of scientifi c and economic experiment on the use of the phytobiotic additive “Farmatan VSO (Butitan)” in feeding broiler chickens of cross Cobb-500 have been provided in the article. The inclusion in the poultry diet of the phytobiotic “Farmatan VSO (Butitan)” in the amount for compound feed Start 800 g/t, Growth and Finish – 400 g/t leads to increase in the live weight of broilers by 3,0 % compared to the control group. At the same time the average daily gain of live weight in the 4th experimental group was 73 g, which was by 2,8 % more than in the control group. The use of phytobiotic additives in the feeding of broiler chickens contributes to the highest livability of poultry (98,1 %). It has been found that the best indicators for feed expenditures have been noted in the 3rd and 4th experimental groups 1,47 and 1,48 kg, which were 3,3 and 2,6 % lower than in the control group. Thus, the authors have found that the highest live weight, average daily gain, livability and lowest expenditures of feed per unit of production diff ered in broiler chickens of 4th experimental group where in the compound feed antibiotic Flavomycin has been replaced on phytobiotic feed additive “Farmatan VSO (Butican)” in the compound feed Start 800 g/t, Growth and Finish- 400 g/t. Production testing of the use of “Farmatan VSO (Butitan)” has shown the high eff ectiveness of phytobiotics as a mean of replacing the feed antibiotic and improving the livestock indicators of broiler chickens rearing.

The article analyses the issues of balanced feeding of broiler chickens and their balanced diet. The results of studies aimed to determine the effect of mixed feeds on the productivity of Arbor Acres cross broiler chickens and the economic efficiency of poultry meat production companies are presented. It was found that broilers from the experimental group, who were fed with improved compound feed with additional sources of proteins and carbohydrates and feed additives exceeded broilers from the control group by their live weight at all ages. At the slaughter age, the average weight was more than 39.2%. The experimental group consumed 10-15% less feed whose conversion was 2.4 and 1.9 kg in favour of the group feeding with the new compound feed. The new compound feed had a positive effect on the viability of broilers: there were no deaths during the period under study. According to the control slaughter results, it was found that the pre-slaughter live weight was higher by 35% in the experimental group. The weight of edible parts increased by 6%. The improved compound feed can be used both in industrial conditions and by poultry farms.

In providing the population with high-quality and cheap beef a signifi cant role is assigned, and in the future will be assigned to beef cattle breeding. The development of this industry and its eff ectiveness depends on the correct use of available feed resources. With the development of the feed industry the main task of which is mainly to ensure that in a small volume, as much as possible, as many sources of nutrients in a highly digestible form, the use of feed additives becomes important. Feed additives as a rule should compensate for the missing elements in the ration. The level and ratio of nutrients in them have a stimulating eff ect on the growth of muscle tissue and the formation of a strong backbone. The purpose of the work was to study the eff ect of the feed additive Vermiculite on the live weight of Kazakh White-headed steers. In order to study the feed additive Vermiculite in the rations of steers a scientifi c and economic experiment has been carried out on the basis of LLP “Terra” in the Kostanay region in the Republic of Kazakhstan. Two groups of steers have been formed for this purpose with 10 heads in each. The control group has received a basic feeding ration consisting of corn silage, haylage, wheat straw, complete feed (wheat, barley). The experimental group has received 200 g of Vermiculite per 1 head/day in addition to the main ration. During the entire period of the experiment the steers of the experimental group had the highest indicators of average daily growth compared to their herdmates in the control group. The highest value of the average daily gain in both groups has been observed in the period of 8–12 months, amounting to 1123,3 g in the control group, and 1159,2 g in the experimental group. The diff erence in favor of the steers of the experimental group was 35,9 g or 3,2 % (P < 0,01). In general during the experiment the diff erence in the average daily gain in live weight between the groups was 31,1 g or 3,5 % in favor of the animals of the experimental group.

A study of the safety of the use of feed additive Liaform for the target species – broiler chickens. Liaform is a yellowish liquid with a specific odor. The feed additive contains lactic acid, formic acid, sodium formate, propionic acid and water. Given the composition of the additive, it can be attributed to two functional groups: preservatives – substances or microorganisms that protect feed from damage by microorganisms or their metabolites, acidity regulators – substances that regulate the pH of feed. For the study was formed on the principle of analogues of 3 groups of broiler chickens of 15 heads (control and 2 experimental) from 8 days of age. Feeding of chickens of the control group was carried out by standard complete feed. Feeding of chickens of the first experimental group was carried out with standard complete feed, in which the feed additive Liaform was added at the rate of 2 g / kg, feeding of chickens of the second experimental group was carried out with standard complete feed, in which feed additive Liaform was applied in 10 times the recommended dose of 20 g/kg. During the experiment, the general condition of the bird, the safety of the bird, zootechnical and hematological parameters were monitored. It was found that the studied feed additive in 10 times the recommended dose does not have a negative impact on productivity, growth and development of broiler chickens, feed absorption. As a result of the use of Liaform feed additive in 10 times the recommended dose, the live weight of broiler chickens in the experimental group was higher compared to the control and lower compared to the recommended dose. The use of a feed additive in 10 times the dose did not have a negative effect on hematological parameters and serum protein levels, did not cause a negative effect on the condition of internal organs.

The article covers addition of chlorella suspension, its effect on nitrogen balance, digestibility of nutrients and amino acids, pig productivity. Various feed additives, micro-element mixtures, and vitamins are used in animal nutrition to deal with the deficiency ofcertain vitamins and mineral elements in the rations. The peculiarity of chlorella suspension as a feed additive is in the ability to cultivate it throughout the whole year and in the availability of optimized technologies for its cultivation and use. Chlorella suspension is rich in proteins, minerals, vitamins, fatty acids and fiber. Introduction of chlorella suspension into pigs’ diets has helped to increase the digestibility coefficients of both inessential (by 7.5 %) and essential (by 2 %) amino acids. Feeding the animals with chlorella suspension has also resulted in the release of nitrogen retained in animals’ bodies by 13 % compared to the control group. The additional use of chlorella suspension in the diet of fattening pigs (large white) was found to increase the average daily gain by 21.9% compared to the control group which did not receive chlorella suspension. The conversion of animal feed to obtain 1 kg of live weight gain in the control group was 5.1 kg, in the experimental group - 4.2 kg, and the conversion rate of feed in the experimental group was higher by 21.4 %.Feeding young pigs with chlorella suspension increases the digestibility of protein by 4.5 %, fiber by 2.0 %, fat - 0.7 %, essential amino acids - 81.6 %. The introduction of chlorella suspension to pig rations leads to an increase in the level of nitrogen in their body by 54.7 %of that taken with feed and 69.15 % of that digested in the body. Pork production profitably using chlorella suspension stood at 12.3 % , which is more by 87,8 % compared to the control group.

Mycotoxins have been formed in feed are secondary metabolites of fungi and are quite stable substances that have teratogenic, mutagenic and carcinogenic effects. An effective way to combat mycotoxins in feed is the use of feed additives that adsorb toxins, prevent their absorption in the gastrointestinal tract of the animal and are excreted from the body. The infl uence of coconut enterosorbent Shelltic Es on fattening and meat qualities of young pigs has been studied. It has been found in the process of fattening that the highest feed digestibility was in pigs of the experimental group, in the diet of which enterosorbent has been added. The results of studies of the chemical composition and technological properties of pork have been provided. The positive eff ect of enterosorbent on precocity, absolute average daily gain of live weight and reduction of feed expenditures per 1 kg of gain has been revealed. In pigs from the experimental group the average thickness of the fat was higher and the area of the “muscle eye” was lower compared with animals of the control group, which indicates that higher rates of carcass yield have been obtained due to faster accumulation of fat tissue. The weight of internal organs of pigs indicates the intensity of metabolic processes in the body. In experimental animals the weight of the lungs was 0,1 kg lower, and the liver and heart were higher by 0,13 and 0,01 kg, respectively. Enterosorbent had no effect on the content of vitamins in the liver of pigs of the compared groups. The content of impurities of organochlorine toxicants and toxic elements in the meat and liver of animals of the experimental group was lower than that of control analogues. Therefore, the use of enterosorbent Shelltic Es promotes more active excretion of them from the body.
