The effect and application of yeast hydrolysate on piglets

      The effects and functions of yeast hydrolysate on piglets are mainly reflected in nutritional supplementation, intestinal health regulation, and immune enhancement. The following is a specific analysis:

1、 Promote growth and nutrient absorption

      Efficient utilization of amino acids and small peptides

      Yeast hydrolysate is rich in free amino acids (such as lysine and methionine) and small peptides. After weaning, the digestive enzyme system of piglets is not yet perfect, and small peptides can be directly absorbed to improve protein utilization and promote daily weight gain (studies have shown that adding 0.5% -1% yeast hydrolysate can increase daily weight gain of piglets by 5% -10%).

The immunomodulatory effect of nucleotides

      The nucleotides in hydrolysates are important raw materials for intestinal mucosal repair, which can alleviate intestinal villus damage caused by weaning stress and improve intestinal absorption function.

2、 Improve intestinal health

      Inhibit the proliferation of harmful bacteria

      The mannooligosaccharides (MOS) in yeast hydrolysates can competitively bind to receptors of intestinal pathogens such as Escherichia coli, reducing their colonization. A certain experiment showed that adding yeast hydrolysate can reduce the diarrhea rate of piglets by 20% -30%.

      Promote the growth of beneficial bacteria

      Hydrolyzed products provide nutritional matrix for probiotics such as lactic acid bacteria, regulate the balance of gut microbiota, and indirectly enhance digestive capacity and disease resistance.

3、 Enhance immunity

Immune activation of β - glucan

      β - glucan in the yeast cell wall can activate the piglet immune system, increase serum IgG levels, and enhance resistance to viral (such as PEDV) and bacterial infections.

Anti stress effect

      Weaning stress can lead to an increase in cortisol, while nucleotides and glutathione in yeast hydrolysates can alleviate oxidative stress and reduce piglet mortality.

4、 Practical application cases

      A large-scale pig farm in the European Union: Adding 0.8% yeast hydrolysate to weaned piglet feed reduced diarrhea rate from 18% to 12%, increased daily weight gain by 8%, and improved feed conversion rate by 5%.

      A Chinese experiment: Comparing the yeast hydrolysate group with the control group, the former showed a 15% increase in feed intake and a significant improvement in disease resistance within 2 weeks after weaning in piglets.

5、 Precautions

      Optimization of dosage: It is recommended to add 0.5% -1.5% to weaned piglets, as excessive dosage may increase costs or cause osmotic pressure imbalance.

      Synergistic effect: When combined with probiotics such as Bacillus subtilis and Clostridium butyricum, the effect is more significant.

      Quality control: Select hydrolysate products with protein content ≥ 50% and nucleic acid content ≥ 8%.

summarize

      Yeast hydrolysate can significantly improve the growth performance and health status of piglets after weaning by providing high-quality protein, regulating gut microbiota, and enhancing immunity.
