how to increase animal immunity, and what to do if animals become diarrhea

The application of yeast extract in the animal field mainly includes the following aspects:

animal husbandry

      Improving production performance: In pig farming, yeast extract Xinpule can replace plasma protein powder, promote intestinal health and development of piglets, and improve lifelong production performance. Adding 2% Xinpule instead of 50% plasma protein powder to weaned piglets aged 21-35 days can increase piglet weaning weight by 500g, feed intake by 29g, daily weight gain by 30g, and reduce feed conversion efficiency by 0.02. Adding yeast hydrolysate to the diet of lactating sows can improve their lactation performance and enhance the growth status of piglets. If 0.3% yeast hydrolysate was added, the weaning survival rate of piglets, average daily feed intake of sows, and milk production increased by 7.49%, 3.8%, and 14.9%, respectively, compared to the control group.

      Enhance immunity: The components in yeast extract can regulate the immune and disease resistance of livestock and poultry. If 5% Xinpule is added to the diet of weaned piglets as a substitute for plasma protein powder, the immune response of peripheral blood mononuclear cells (PBMCs) is enhanced by 12.36%, and the phagocytic activity of neutrophils is increased by 6.7%.

      Improving intestinal health: Yeast extract can regulate the balance of gastrointestinal microbiota, effectively inhibit the proliferation of pathogenic microorganisms, and promote the growth of beneficial bacteria. Pan Shude et al. found that yeast nucleic acid can increase the number of bifidobacteria and lactobacilli in the intestine of piglets, while reducing the number of Escherichia coli.

aquaculture

      Relieve the effects of toxins: Yeast cell wall extract can effectively reduce the residual aflatoxin in the body of turbot, alleviate the impact of toxins on the health of turbot, and also have a positive effect on the health of aquatic animals.

      Improving immunity and antioxidant capacity: Researchers fed California bass with a feed containing yeast cell wall extract for 8 weeks and found that its serum immunity, anti-inflammatory, and antioxidant capacity were significantly improved. The structure and function of the gut microbiota were also improved, and the gut health status was enhanced.

      Promoting growth: Adding yeast cell wall extract to the feed of South American white shrimp can improve its growth performance and enhance its growth parameters. Research has shown that adding 1.0% yeast cell wall extract to feed shrimp has the greatest impact on the composition of gut microbiota, increasing the abundance of beneficial bacteria in the shrimp gut microbiota.

Pet keeping

      Enhance palatability: Yeast extract contains high concentrations of glutamic acid, which can produce umami or meaty flavors, stimulate the sense of smell and taste of pets such as cats and dogs, thereby increasing their interest and appetite for food.

      Providing nutrition: Rich in amino acids, nucleotides, and other organic compounds, it can provide necessary protein and vitamins for pets, especially B vitamins, which help with their growth and development, as well as maintain the health of their skin and hair.

      Supporting Health: Beneficial for pets' immune systems and even helps regulate blood sugar levels. Dietary fiber in yeast extract can promote intestinal peristalsis in pets, aid digestion, and maintain normal intestinal function.
