weighing the raw materials according to the proportion;
mixing the composition for reducing the peculiar smell of excrement, corn, flour, wheat middling, methionine, corn protein powder, imported meat and bone meal, lysine, calcium hydrophosphate and soybean meal, sieving and puffing to obtain feed particles;
coating the beef tallow, the chicken fat and the lard on the pellet feed, and then sequentially coating the meat paste and the chicken hydrolyzed powder to obtain the feed for dogs.
The principle and the beneficial effects of the invention are as follows:
the main components of Yucca Schidigera extract are steroid saponin, resveratrol and saccharide complex. The urease inhibitor can inhibit urea from decomposing into ammonia gas and promote microbes to convert the ammonia gas into microbial protein, so that the production of ammonia gas in excrement and urine is reduced, the concentration of harmful gases such as ammonia gas and hydrogen sulfide in animal houses is reduced, and the feeding environment of livestock and poultry is improved.
The cellulase, the protease and the glucanase belong to biological enzyme preparations, wherein the cellulase can decompose cellulose components in the feed, so that the satiety and the feed palatability of animals are reduced, and the feed intake is increased; the protease can decompose macromolecular protein into micromolecular polypeptide or amino acid, so that the protein is easier to absorb and utilize, the digestion and absorption rate of the protein is improved, the discharge amount of nitrogen-containing substances in excrement is reduced, and the odor of the excrement is further weakened; the glucanase can reduce anti-nutritional factors in the feed and improve the absorption of nutrients.
The lactobacillus acidophilus is a microorganism beneficial to canine intestinal tracts, belongs to a microecological preparation, and can inhibit harmful floras such as escherichia coli and the like and regulate canine intestinal tract health. Not only can improve the intestinal absorption, but also can reduce the diarrhea of dogs caused by intestinal pathogenic bacteria and the pungent smell of excrement thereof.
The fructo-oligosaccharide and inulin not only provide nutrition basic substances for the microecological preparation, but also play a role in protecting the digestive tract of dogs to a certain extent, promote the digestion and absorption of substances and improve the growth performance of dogs.
Compared with the prior art, the invention has the following beneficial effects:
the composition for reducing the dog excrement peculiar smell uses cellulase, protease and beta-glucanase as biological enzyme preparations, can assist a dog organism to decompose and digest nutrient substances, improve the digestibility of protein, reduce the discharge amount of nitrogen-containing substances in excrement, reduce the activity of the dog urease by matching with yucca extract, and further reduce the decomposition of urea into ammonia gas; the lactobacillus acidophilus is used as a microecological preparation to adjust the balance of canine intestinal flora, thereby inhibiting the excretion of excrement with peculiar smell and ensuring the absorption of nutrient substances; the fructo-oligosaccharide and inulin can improve the absorption and utilization of nutrient substances, and are also nutrient substances of lactobacillus acidophilus. The composition can reduce the generation of volatile irritant gas in feces discharged by dogs and further reduce the odor of feces.
Furthermore, in the feed for dogs, the contents of protein and vitamins are rich, the nutrition substances are reasonably matched, the requirements of dogs on various nutrition substances are met, the nutrition substances are digested, absorbed and utilized to the maximum extent, and the material basis that excrement generates odor is reduced. Has obvious effect on improving digestibility, in particular on reducing the pungent smell of the excrement.
