Fermented feed capable of improving laying performance and egg quality of laying hens

Abstract

The invention discloses a fermented feed capable of improving the laying performance and the egg quality for laying hens. The fermented feed comprises the following raw materials by weight: 58-63.7 percent of corn, 17-20 percent of soya bean meal, 1-1.5 percent of fish meal, 3-5 percent of bran, 1.5 percent of bone meal, 4-7.67 percent of seashells, 0.3 percent of salt, 0.15 percent of methionine, 0.1 percent of trace elements, 0.03 percent of decavitamin, 0.05 percent of sodium bicarbonate, and 0.1-0.15 percent of enzyme-rich probiotics for poultry; the fermented feed is prepared by adding 380-460 kg of water in each ton of feed, and hermetically fermenting for 24-48 h before feeding. The fermented feed has the advantages that the feed intake of the laying hens is increased, the feed utilization rate is increased, the fermented feed does not contain antibiotics, but contains probiotics, such as viable bacteria, enzymes and oligopeptides, of various somatomedin, can improve the intestinal environment of poultry, enhances the immunity, can also promote the oocyte development and increase the spawning quantity, improves the laying rate, enhances the egg quality, and besides, can also reduce the pollution to surrounding environment, and brings remarkable economic, social and ecological benefits to locals applying the fermented feed.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a fermented feed capable of improving the laying performance and egg quality of laying hens. Background technique [0002] For a long time, people have been using antibiotics and antibacterial drug growth promoters in animal diets to maintain animal health, promote growth and improve feed utilization. However, while the extensive use of antibiotics and antibacterial drugs inhibits pathogenic bacteria, it also destroys the microecological balance in animals, leading to the susceptibility of animals, especially young animals, to pathogenic microorganisms, increasing the occurrence of digestive tract diseases, and antibiotics and antibacterial drugs Long-term use will produce drug-resistant strains. Under certain conditions, these strains can transfer drug-resistant factors (R factors) to other bacteria, making other heterogeneous bacteria also become drug-resistant strains...

However, while the extensive use of antibiotics and antibacterial drugs inhibits pathogenic bacteria, it also destroys the microecological balance in animals, leading to the susceptibility of animals, especially young animals, to pathogenic microorganisms, increasing the occurrence of digestive tract diseases, and antibiotics and antibacterial drugs Long-term use will produce drug-resistant strains. Under certain conditions, these strains can transfer drug-resistant factors (R factors) to other bacteria, making other heterogeneous bacteria also become drug-resistant strains, causing serious harm to the prevention and treatment of human diseases; especially The resulting drug residues not only seriously affect the quality of animal products, but also directly threaten human health and safety
