Application of Feed Additives to Different Animals

Feed additives refer to small or trace substances added in the process of feed production, processing and use. They are used in small amounts but have significant effects. Feed additives are inevitable raw materials used in the modern feed industry. They have obvious effects on strengthening the nutritional value of basic feeds, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of animal products.

Feed additives are divided into microbial feed additives and Chinese herbal medicine feed additives. Among them, the microbial feed additive is a microbial product that replaces or balances one or more bacterial strains in the animal ecosystem. In a narrow sense, it is a microbial product that can stimulate the reproduction and growth of its own beneficial bacteria while resisting the growth of harmful bacteria. Microbial feed additives contain a large number of beneficial bacteria (active lactic acid bacteria, bifidobacteria, bacillus), compound enzymes, chelated peptides, mold removers, etc. After entering livestock and poultry as feed, they can multiply rapidly. The metabolites neutralize enterotoxin and inhibit the growth of other harmful flora. On the other hand, it forms a normal microbial flora in the host, synthesizes the main vitamins for the host, provides nutrients and prevents the invasion of pathogenic bacteria.

1. Chicken

The digestive tract of chickens is relatively short, and the intestinal mucosal barrier is fragile. Under intensive farming conditions, compared with animals with long digestive tracts, they are more vulnerable to harmful microorganisms, leading to the occurrence of various diseases. The use of feed additives is one of the effective means to prevent and treat intestinal diseases and improve the production performance of broilers and laying hens. Broilers grow fast and are greatly affected by the environment in intensive production. The application of feed additives can improve the balance of intestinal flora, reduce the incidence and mortality of intestinal diseases, increase the slaughter weight, reduce the feed to meat ratio, and can reduce the The emission of ammonia, hydrogen sulfide and other harmful gases in the chicken house improves product quality. The application of feed additives in laying hens can not only prevent diseases, improve production performance and feed remuneration, but also improve egg quality. Studies have shown that adding feed additives to the diet of laying hens can increase the Hastelloy unit of eggs, reduce the cholesterol content of eggs, and have the effects of improving eggshell thickness and reducing soft-shell eggs.



2. Pig

Current research and applications show that feed additives have achieved good application results in the breeding of piglets, sows and fattening pigs. Adding feed additives to piglet diets can promote piglet intestinal development, improve intestinal health, reduce diarrhea rate, and improve piglet growth rate and feed conversion rate. For lactating piglets, adding feed additives helps to establish the dominant flora of probiotics; for weaned piglets, it can improve diarrhea, growth retardation and other adverse effects caused by factors such as the secretion of their own digestive enzymes and the antigenicity of the diet. Studies have shown that the use of feed additives in sow diets can improve gut health and improve sow immunity and reproductive performance. After adding feed additives, it can improve the ability to adjust the balance of gastrointestinal flora, increase the feed intake of sows during lactation, inhibit body weight loss, increase the fat and protein content in sow milk, and improve the survival rate of weaned piglets and weaned piglets. weight. Adding feed additives to the diet of finishing pigs can increase feed intake and feed conversion rate, improve health status, shorten the finishing period, and have the effect of improving quality and reducing environmental pollution. Studies have shown that adding feed additives can reduce the diarrhea rate of fattening pigs, improve immunity, increase feed intake and feed digestibility, thereby improving the utilization rate of rations and reducing the ratio of feed to meat. In addition, feed additives have a certain promoting effect on increasing intramuscular fat and increasing the content of essential fatty acids, which can improve the quality of pork.

3. Ruminants

Studies have shown that feed additives can improve the weight gain rate of meat ruminants such as mutton sheep and beef cattle, increase the net meat rate of the carcass, and improve the meat quality. For milk-producing ruminants, feed additives can increase milk production, prolong the peak of milk production, increase milk fat rate, reduce the number of somatic cells in milk, and improve milk composition. It also has a certain effect on the prevention and treatment of mastitis and reproductive diseases. For calves whose digestive tract is not yet developed, the use of additives can promote the establishment of calf gastrointestinal flora, regulate the balance of flora, and reduce the occurrence of diarrhea in calves. In addition, the use of feed additives can promote the weight gain of calves.

4. Aquatic products

The application of feed additives in aquatic products is reflected in two aspects: bait and water purification. Feed additives can improve the micro-ecological balance of aquatic animals, promote growth and development, and play a role in preventing diseases and improving production performance. Probiotics can colonize the intestinal tract of fish, promote the growth and development of fish, and improve disease resistance. Feed additives can reduce the incidence of shrimp, improve the survival rate and yield. Feed additives can be used as immune stimulators and adjuvants for aquatic animals to promote the development of immune organs, improve humoral immunity, and improve immune function. This effect has been verified in a variety of aquatic animals. Photosynthetic bacteria and nitrifying bacteria in feed additives can consume organic matter in water, remove ammonia nitrogen, hydrogen sulfide, nitrite nitrogen, etc., and are currently important beneficial microorganisms for improving aquaculture environment. Good application effect in aquaculture

Ear Plugs vs Ear Muffs for Shooting

图片
What You Need To Know About Ear Plugs and Shooting Muffs What is Ear Protection in PPE? Anyone in the vicinity of gunfire needs hearing protection, so  ear plugs  and/or  ear muffs  are some of the most essential pieces of safety gear that you can have when you’re going shooting. Shooting ear protection (often called “ear pro”) is necessary for everyone on the range, including shooters and bystanders. This is also true for hunters in the field. Today, many types of hearing protection devices are available on the market that won’t hamper hearing game and maintaining situational awareness. Any noise over 85 decibels (dB) can cause permanent hearing loss, which can be compounded by other factors like shooting indoors. Guess what? A .22 Long Rifle, one of the smallest calibers used for hunting and recreational shooting, produces at least 140 dB using standard loads. Hearing damage can occur in as little as one shot, and the effects are cumulative over time with repeated ...

What are Post-Consumer Recycled (PCR) Plastics?

图片
Post-Consumer Recycled (PCR) plastics  refer to plastic materials that have been previously used by consumers and then collected, processed, and repurposed to create new products. Unlike pre-consumer recycled plastics, which are recycled during the manufacturing process before reaching the consumer, PCR plastics come from items that consumers have used and discarded. Here's a breakdown of key points related to Post-Consumer Recycled (PCR) plastics: Collection Process: PCR plastics  are collected from various sources, including household recycling bins, collection centers, and waste management facilities. The plastics collected can include bottles, containers, packaging, and other items that consumers have disposed of. Sorting and Processing: After collection, the  recycled plastics  go through a sorting and processing phase. During this stage, the plastics are separated based on their type (e.g., PET, HDPE) and color. Any contaminants are also removed to ensure the r...
