Application of montmorillonite in livestock and poultry production
1. Application of MMT in poultry production
MMT can reduce the harm of mycotoxins and heavy metals to poultry, improve the production performance and production of poultry.
It can improve product quality, enhance animal immune function and small intestine digestion and absorption capacity. Broiler vs Minerals The absorption and utilization of elements are relatively sensitive, MMT can reduce the impact of lead, fluorine, cadmium and other elements in the feed on thebroiler chickens, but there is also a phenomenon that the utilization and deposition of elements such as zinc, iron, phosphorus, and manganese are reduced. In actual production, it is necessary to appropriately supplement corresponding mineral elements. Studies have found that natural MMT Both modified MMT and modified MMT can increase the average daily gain and plasma total protein and albumin content of broilers amount, significantly reduced thymus index, MMT can alleviate the adverse effects caused by AFB1, modified MMT The effect is better. 1% sodium sulphate-based montmorillonite can reduce chicken mortality and improve chicken Beneficial factor content in peritoneal effusion. Adding nano-copper-loaded MMT can maintain intestinal mucous in broiler chickens The good shape of the membrane can improve the activities of maltase, aminopeptidase and alkaline phosphatase in the small intestinal mucosa, Reducing the number of intestinal Escherichia coli and Clostridium perfringens can effectively improve the body weight an feed utilization efficiency. Adding 0.1-0.3% of roasted modified MMT adsorbent to the diet can Effectively reduce the toxic effect of moldy corn containing 170μg/kg AFB1 on meat ducks, improve Apparent and true metabolic rates of dry matter, aspartate, glycine, and proline, but not Can completely eliminate the toxic effect. Supplementation of copper-loaded layered MMT silicate formulations in diets is effective Improved growth performance of meat ducks, which may be related to the adsorption of mycotoxins and heavy metals by MMT.
2. Application of MMT in laying hen production
Adding 0.1-0.5% MMT in the feed will improve the performance of laying hens, improve the color of egg yolk, improve the quality of eggshell, and also help improve intestinal function. Rohmann’s eggs were studied at 75 weeks of age Adding 1.5‰ MMT to the chicken diet, it was found that the daily egg production increased significantly, and the feed-to-egg ratio tended to decrease. The abundance of beneficial microorganisms in the cecum tended to increase, and the content of lipopolysaccharide in serum and eggs decreased. It has the function of improving intestinal morphology. Add 1.5‰ of Calcium MMT, it was found that the egg production rate and daily egg weight were significantly improved, and the eggshell thickness and yolk index were significantly improved. MMT can also reduce drug residues and reduce the risk of human ingestion of drugs. MMT can To reduce the accumulation of α-HCH in laying hens and eggs, and reduce the risk of human intake of α-HCH risk.
3. Application of MMT in pig production
The effect of MMT on pigs is mainly manifested in reducing piglet diarrhea, which may be related to the fact that MMT can inhibit Intestinal harmful bacteria, maintenance of intestinal villi morphology and intestinal barrier integrity in piglets. repeated reality Experiments can confirm that MMT has a protective effect on the intestinal tract of weaned piglets, and can effectively increase the ileal villi surface area, increased duodenal villi height/crypt depth, and significantly prolonged Cheme retention time in the digestive tract. It was also found that nano-MMT was effective in improving the duodenum of weaned piglets. Significant contributions to villus height and villus height/crypt depth in the intestine, jejunum and ileum use. In terms of preventing diarrhea, the effect of MMT on controlling diarrhea in piglets is equivalent to that of zinc oxide. Significantly reduces feed costs. MMT can increase the average daily feed intake and daily gain of weaned piglets, High piglet performance. In addition, MMT can also reduce the toxic effect of mycotoxins on pigs, Reduce liver damage, thereby improving the growth performance of pigs, especially the best effect on detoxification of AFB1. MMT does not adsorb the polar vomitoxin and zearalenone well, but the organic positive The ion-modified montmorillonite increases the hydrophobicity of the mineral surface, which can significantly improve the resistance to non-polar
Absorption of toxins.
4. Application of MMT in cattle breeding
Appropriate addition of MMT can reduce the harm of mycotoxins in feed to dairy cows, increase milk production, Improving various indicators of milk can also improve rumen fermentation and rumen microbial status, and promote nutritional Digest and absorb nutrient substances, improve breeding production. Adding an appropriate dose of MMT can affect the daily average Feed intake, milk yield, 4% standard milk yield, somatic cell count, and milk fat percentage had positive effects. It is recommended that MMT be safely added to the diet (mycotoxin content is within the safe range) The dosage should not be higher than 2.0%, and the recommended dosage is 0.5-1.5%. Add 1.5% of MMT can significantly improve the daily gain and feed conversion rate of beef cattle, and effectively improve the contents of cadmium, lead, and zinc in tissues such as the liver decreased, the contents of copper and iron in the spleen decreased, and the contents of liver increased. Iron content in viscera and muscle tissue, which may be related to the complex composition of MMT, which contains a variety of mineral elements Toxins and the adsorption of toxic and harmful substances.
Summary
So far, studies have found that MMT can maintain the intestinal barrier, prevent diarrhea in piglets, improve Animal health, improving production performance, improving product quality, improving rumen function, etc. The modified MMT also has good antibacterial function, and has the function of absorbing mycotoxins. Potential for additives and novel antimicrobial agents. MMT and enzyme preparations, microorganisms, organic trace elements, etc. The synergy and compounding effect of feed additives can also better solve the serious problem of mycotoxin pollution question
