Effect of fish feed concentrate on egg production of laying hens

The article contains materials of scientific research on the using of fish feed concentrates in the feeding of laying hens. It has been proved experimentally that this feed concentrate has a positive effect on the egg production of laying hens of the cross Haysex White. Thus, when this supplement was included in the diet of laying hens, the following results were obtained: egg production in the experimental groups increased and were higher on 13.3; 15.7 and 18.3%, the amount of egg mass-on 15.9; 18.3 and 34.6% higher than in control group

Effect of marine feed additions on the digestibility of poultry nutrients

Poultry farming is one of the most important branch of animal husbandry. Poultry is very sensitive to a lack of protein, vitamins, microelements and macroelements. The lack of these substances is very bad for the health, development, growth and productivity of poultry. Primorsky Krai is rich in seafood, which is extracted in large quantities. In the process of processing seafood, a large amount of waste remains, which could be used for feed purposes, for feeding farm animals and poultry. The use of seafood waste would solve the problem with a nutrient deficiency in the diets of poultry. The digestibility of feed nutrients is a secondary indicator of their nutritional value. The better the nutrients are digested in the animal's body, the more nutritious the food is. In our research work, we studied the influence of marine hydrobionts on the digestibility of dietary nutrients

Effect of marine feed addition on growth of poultry

Poultry farming is one of the most precocious and important branches of animal husbandry. It makes it possible to get food products such as meat and eggs in the shortest time. The main factor affecting the development of poultry farming is the feed base. For poultry, the lack of protein and minerals is very harmful. Far East has all the opportunities to realize its genetic potential. Primorye region makes it possible to widely use inexpensive seafood and waste products, as well as plant raw materials in animal and poultry feeding. Marine and fish products, as well as waste from their reprocessing, are rich in protein and minerals necessary to ensure the fullness of animal and poultry rations. Additions of marine origin have antioxidant, radioprotective activity, increase the body's resistance to diseases, increase the immune system, and improve metabolism
