Why add feed additives? The impact of feed additives on poultry!
Feed additives are small amounts of nutritive or non-nutritive substances added to the feed to meet the special needs of animals. The development of modern intensive aquaculture makes feed additives play an increasingly important role in poultry feed processing. Rational use of feed additives can increase feed utilization, prevent diseases, promote healthy growth of poultry, improve product quality, enhance product competitiveness, and create better economic efficiency. Today, Xiaobian will introduce to you why you need to add feed additives? The impact of feed additives on poultry!
Why add feed additives?
In general feed, the nutrients required by animals in growth, reproduction and production can basically be met, but if you want to obtain higher production efficiency, the nutrients in the feed may be somewhat insufficient, and additional additions are necessary, such as : Increase the litter size and birth weight of sows, speed up sow labor, increase milk quality and quantity, etc., increase weaning litter weight, increase growth rate, reduce feed-to-meat ratio, improve meat quality and flavor, etc., if you want to improve comprehensively, A single feed nutrition is not enough, and must be supplemented.
In general feed, there are some functions that antibiotics do not have, and may even replace antibiotics in some aspects, such as: mold remover, substances that remove toxins in sows, etc., improve immunity, improve intestinal reduction Diarrhea, etc. Inhibits the reproduction of harmful bacteria and keeps the intestinal flora normal.
Supplementary nutrition, in the process of pig production, due to various reasons, some of the nutrients in the feed may be lost, or the nutrition of the feed is not enough at a particular stage, etc., which cannot meet the growth or production needs, such as: feed Some of the vitamins will be oxidized during long-term storage in summer; due to the large number of fetuses in sows, the protein, energy, vitamins and minerals required are not enough, and additional additions are required.
Optimize the ecological environment. In the process of animal intestinal metabolism, the prebiotics and enzyme preparations in the feed additives decompose the crude protein, phytase and anti-nutritional factors that are not easy to be absorbed and utilized by animals, and effectively cut off the source of ammonia and odor. , the concentration of harmful gases in animal feces has been effectively reduced, the breeding environment has been improved, the harm of ammonia to the human body has been reduced, and the occurrence of respiratory and intestinal diseases of livestock and poultry has been prevented.
If you want to better breed animals, feed additives are essential substances.
Effects of feed additives on poultry:
1. Classification and main functions of feed additives
Feed additives are divided into two types: nutritional feed additives and general feed additives (including pharmaceutical additives).
Nutritional additives include feed-grade amino acids, vitamins, mineral trace elements, non-protein nitrogen, etc. Its main function is to provide the nutrients necessary for the healthy growth of poultry, improve the amino acid balance of the diet, improve the protein utilization rate, and promote the growth of poultry; improve the quality of meat; promote calcium absorption; resist stress; improve disease resistance; improve and improve Animal digestive function to prevent the occurrence of systemic digestive diseases.
General feed additives include feed drug additives (antibiotics and synthetic antibacterials), prebiotics, enzyme preparations, acidifiers, Chinese herbal medicines and plant extracts, mildew inhibitors, feed preparations, and flavorings. General feed additives are used to improve feed utilization, ensure feed quality and quality, attract food and flavor, and benefit animal metabolism and health. Antibiotics in modern farming have been gradually replaced by pollution-free feed additives. Natural medicinal plant products, Chinese herbal feed additives, micro-ecological preparations (probiotics and prebiotics), enzyme preparations, oligosaccharides, amino acids, vitamins, acid preparations, etc. It is a pollution-free feed additive. It has comprehensive functions and rich nutrition. It is fed together with food without residue and does not produce drug-resistant strains and toxic side effects. Poultry products raised with these additives are sought after and loved by people.
2. Effects on poultry performance and physiology
Feed additives play a very important role in the production performance and physiological function of poultry. The commonly used additives in poultry farming are vitamins, probiotics, enzymes, oligosaccharides, bioactive peptides and Chinese herbal feed additives.
Micro-ecological preparations can improve the bacterial flora in chickens, reduce the incidence of salmonella and coccidiosis, and have a good effect on improving the disease resistance and immunity of chickens; feeding chickens with micro-ecological preparations can improve serum and intestinal The enzyme activity in the tract increases, which is conducive to the digestion and absorption of nutrients and reduces the feed-to-meat ratio; adding vitamin preparations to the drinking water of laying hens in summer can increase heat dissipation and relieve the heat stress response of chickens. Chinese herbal medicine feed additives are widely used in the breeding of livestock products and have bacteriostatic effect, which can improve the balance of intestinal flora in poultry and promote the absorption and utilization of feed; it can improve production performance, reduce production costs, enhance immunity, and promote growth. Improve the quality of poultry ketone bodies, natural pollution-free and enhance the competitiveness of products, especially in the breeding of broilers, Chinese herbal compound preparations can reduce the abdominal fat rate in the body and increase the rate of leg muscle and breast muscle of broilers; oligosaccharides can improve the intestinal tract. Microbial flora can promote the growth of broilers; commonly used enzyme preparations such as protease, amylase, lipase, etc. can make up for the digestive problems caused by insufficient digestive enzymes, and improve the feed conversion rate and economic benefits.
3. Effects of feed additives on fat metabolism in poultry
Additives in feed have a very important impact on fat metabolism. Excessive body fat in poultry will not only cause waste of feed but also affect the quality of the carcass. In laying hens, fatty liver will affect egg production. Some additives in the feed have an impact on the fat metabolism of poultry: daidzein can promote the fat metabolism of animals and improve the immunity of the body, and L-carnitine can inhibit the synthesis of fat and promote the decomposition of fat, thereby improving the quality of meat taste. Betaine, niacin, and chitosan have the effect of reducing body fat synthesis, increasing fat breakdown or redistributing body fat.
4. Pay attention to feed additives
The rational use of feed additives has a positive impact on the poultry industry. While providing the necessary nutrients for the body, it can resist stress, protect the immune organs of the body, and improve immunity; enhance material metabolism and feed conversion rate, and increase economic benefits for farmers. Several problems are prone to occur when feed additives are used: (1) Insufficient or too high doses are used. Excessive use will also affect the health of livestock and poultry, such as trace elements: iron, copper, and zinc can promote growth when used normally, but Excessive addition affects the normal metabolism of birds. (2) The abuse of antibiotics results in the formation of drug residues and the destruction of the ecological balance of microorganisms in the body. (3) The use of hormones can promote growth, and a large amount of use will remain in animal food. People use such food for a long time to affect the hormone level of the human body, and there will be risks of precocious puberty, carcinogenicity, teratogenicity and mutagenesis. Now many countries have banned the addition of antibiotics to feed, we call on the majority of farmers to use green, safe and pollution-free feed additives in the breeding process.
Why add feed additives? The impact of feed additives on poultry! That's all for you here, I hope it helps! Feed additives are the inevitable raw materials used in the modern feed industry. They have obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of animal products. This is the Ministry of Agriculture's definition of feed additives, and obviously it plays a very important role in our farming process.
