Additives to increase egg production rate of laying hens
Sodium bicarbonate: commonly known as baking soda, is a weak base, has the effect of dissolving mucus, inhibiting acid and increasing appetite, can increase the utilization of protein and energy in feed, and can partially alleviate the bad caused by insufficient lysine in feed. The effect can increase the egg laying rate of about 10% and fertilization rate of 4%-5%. Sodium sulfate: commonly known as Glauber's salt, Pi Dong. Sulfur is an essential element of animals, and the absorption rate and biological potency of sulfur in sodium sulfate are higher than those of other sulfates. Sulfur in sodium sulfate can be used as a source of feed sulfur, reducing the adverse effects of insufficient egg-cystine in feed on production performance of laying hens. According to the experiment, 0.3% sodium sulfate was added to the feed of laying hens, and the egg production rate, egg production, and economic benefits increased by 2.4%, 3.7%, and 10.6%, respectively. Organic Rare Earth: There is a close relationship between rare earth elements and essential elements of livestock and poultry, enabling the nutrients taken into the body to be more fully absorbed and utilized, thereby improving the production performance of livestock and poultry and reducing feed consumption. The tests showed that 300 mg of organic rare earth containing 30% rare earth oxides was added to each kg of product layered egg feed, the egg production rate was increased by 3.6%, feed consumption was reduced by 2.4%, and the income per 100 chickens increased by 118 yuan. Zeolite powder: Zeolite has a porous structure and has a large absorption surface. It can selectively adsorb toxins in animals and prolong the residence time of feed in the digestive tract. It can increase feed utilization and egg production rate in laying hens. Have a health effect and reduce the incidence of disease. Studies have shown that adding 1.5% to 3% of zeolite powder to laying hens' diets can increase egg production by 14% to 19%, and feed consumption can be reduced by more than 10%. Betaine: The chemical name is glycine trimethyl inner salt. The replacement of choline chloride in feed with betaine can effectively improve the stability of multivitamins in feed. Compatibility with anticoccidial drugs can also improve gastrointestinal tract function and improve anticoccidial efficacy. Beta-carotene: Adding 30-60 mg of β-carotene per kilogram of laying hens has a good effect on improving egg laying rate, egg yellowness, and egg appearance quality. When 50, 100, and 150 mg of β-carotene were added to the feed per kilogram of chicken, the egg production rate increased by 2.51%, 5.02%, and 2.73%, respectively, and both the fertilization rate and the hatching rate increased. Trace element chelate: It is the third generation trace element additive product following inorganic salt and organic salt. It is not only compatible with the dual nutrition use of trace elements and amino acids in animals, but also close to the natural form of enzymes, which is beneficial to the synthesis and activation of enzymes, and it is easy to absorb and improve the biochemical physiological functions of animals. Flavorings: Chicken flavors are mainly extracted from garlic and pepper. Garlic can promote appetite, have bactericidal effect, prevent diarrhea and prevent egg production from falling. Biochemical fulvic acid: Biochemical fulvic acid has significant effects on regulating the body's physiology, improving anti-stress ability and production performance. Adding 15 milligrams of biochemical fulvic acid per kilogram of hens' diets can significantly increase the production performance of laying hens, increase the egg production rate by 10% and the feed utilization rate by 15.1%. Biochemical fulvic acid has a good effect on the recovery of egg production after the outbreak of Newcastle disease. Dihydropyridine: is a new type of antioxidant and livestock growth promoter. Tests have shown that adding 150 mg dihydropyridine to each gram of layer diet can increase the egg laying rate at the end of the laying period by 11.48%-15.04%, reduce feed consumption by 11.61%-17.17%, and save 13.8% of the cost of raising chickens. Extended egg production period.
