Testing of silos from legume-cereal grass mixtures and feed additives in the feeding diets of dairy cows

The production approbation of silos prepared from legume-cereal grass mixtures with the use of an unconventional feed crop – eastern goat and preserved with Biosib biopreparation in experimental versions was carried out. The chemical composition and nutritional value of feed were determined, the structure of feeding rations was calculated, the dose of the energy feed additive was determined. In the balance experiment, the digestibility of the main nutrients of feed was calculated, the hematology of blood was studied. The productivity, costs of concentrated feed and energy for the production of 1 kg of milk are estimated, the main physical, chemical and technological properties of milk from the point of view of butter production are studied, the economic efficiency of using silos in the feeding rations of dairy cows is established.

UNCONVENTIONAL FEED ADDITIVES: WHEY-MINERAL-VITAMIN SUPPLEMENT IN THE DIET OF YOUNG PIGS ON FATTENING DURING THE TESTING PERIOD

The article presents the data of production testing on young pigs on fattening when fed as part of a feed mixture of the best dosage of a serum-mineral-vitamin supplement in the amount of 30 g per day per head. The daily increase during the study period was 531 g in the control group and 548 g in the experimental group, or 3.2% more. The exchange energy costs per 1 kg of gain were 10.4% lower in the experimental group compared to the control group animals. The level of profitability of pork production was 1.6% higher in the experimental group.

Influence of unconventional feed supplement on productivity and quality of laying hens

Показана эффективность использования в рационах промышленных кур-несушек натуральных кормовых добавок, изготовленных из сырья растительного происхождения (элеутерококка колючего, морской бурой водоросли, патринии скабеозолистной, крапивы двудомной, муки из шелухи шишек кедрового ореха). Выявлено положительное влияние кормовых добавок на обменные процессы в организме кур, что способствовало повышению их производительных качеств и снижению коэффициента конверсии корма. The results of effective use of the spiny eleuterococcus, brown seaweed, Dahurian patrinia, common nettle, flour from pine cone shell as the feed supplement from raw materials of plant origin in addition to the main ration of industrial laying hens are presented in this publication. The positive influence of the feed supplements on metabolic processes in the hen organisms was discovered and this fact contributed the increase of productive qualities and improvement of feed conversion.

Growth and development, meat pig productivity at use in their diets unconventional feed additives in Yakutia

Relevance. The article presents data on the influence of unconventional feed additives of the Suntar zeolite on growth and development, physiological parameters, as well as meat productivity of fattening pigs in Yakutia.Methods. For the experiments, 3 groups of animals were formed with 15 animals each. The rations of the experimental animals were identical, except for additional feeding of unconventional feed additives in the experimental groups.Results. The use of Suntar zeolite in experimental groups of pigs allowed to improve the growth and development of animals by 3.02% and 6.68%, respectively. At the same time, in terms of average daily growth, the control group of pigs yielded to experimental groups of animals by 7.42% and 15.17%. During the experiments, a difference was found in the indices of the morphological composition of fattening young pigs. The control group of young animals by the number of red blood cells yielded to experimental groups of pigs by 2.00% and 4.00%. By the number of leukocytes, the control group of the group lost 1.02% and 1.16% to the experimental groups of animals. At the end of the experiment, a control slaughter of animals was carried out. Qualitative differences were established between the superiority of the experimental groups over the control group in terms of carcass weight by 5.25% and 1.98%, by internal fat yield by 0.71% and 0.64%, slaughter yield by 0.71% and 0.64 %, according to the meat content by 0.9% and 2.97%, as well as the share of fat 0.54% and 0.74%. Thus, the use of unconventional feed additives of the Suntar zeolite in the fattening of young pigs has shown effectiveness.

Reduce, Reuse, Recycle for Food Waste: A Second Life for Fresh-Cut Leafy Salad Crops in Animal Diets

The world’s population is growing rapidly, which means that the environmental impact of food production needs to be reduced and that food should be considered as something precious and not wasted. Moreover, an urgent challenge facing the planet is the competition between the food produced for humans and the feed for animals. There are various solutions such as the use of plant/vegetable by-products (PBPs) and former foodstuffs, which are the co/by-products of processing industries, or the food losses generated by the food production chain for human consumption. This paper reviews the by-co-products derived from the transformation of fresh-cut leafy salad crops. A preliminary nutritional evaluation of these materials is thus proposed. Based on their composition and nutritional features, in some cases similar to fresh forage and grasses, this biomass seems to be a suitable feedstuff for selected farm animals, such as ruminants. In conclusion, although the present data are not exhaustive and further studies are needed to weigh up the possible advantages and disadvantages of these materials, fresh-cut leafy salad crops represent a potential unconventional feed ingredient that could help in exploiting the circular economy in livestock production, thereby improving sustainability.

Resource-saving technologies for preparing fodder crops

A modern animal husbandry needs balanced feeding with rational use of feed and the maximum involvement of unconventional feed. At the same time, issues of increasing the nutritional value of feeds, improving quality, reducing the share of cereals remain urgent, since they occupy a significant part in the composition of the diet and cost structure. The application of modern feed processing technologies increases the efficiency of their use, increases the performance of animal husbandry, as evidenced by numerous experiments. The organization of feed production based on own feed resources significantly reduces the cost of production. The application of a number of technologies has been discussed and justified, which allows obtaining feed with high zootechnical and consumer characteristics, as well as with high rates of nutrition, digestibility and biological value with a significant reduction in the cost of feeding.
