What are the benefits of yeast hydrolysate for cows and beef cattle

The application of yeast hydrolysate in cattle farming can indeed bring various benefits. The following is a detailed analysis of its specific benefits and scientific basis:

1. Promote digestion, absorption, and rumen health
      Rumen microbiota regulation: Yeast hydrolysates are rich in nucleotides, small peptides, and β - glucans, which can selectively stimulate the growth of fiber degrading bacteria (such as Helicobacter pylori) in the rumen and improve the degradation efficiency of roughage (such as straw and hay). Research has shown that adding yeast hydrolysate can increase fiber digestibility by 5% -10%, thereby improving feed energy utilization efficiency.

      Stable rumen pH: By promoting the proliferation of lactic acid utilizing bacteria, reducing lactate accumulation, and lowering the risk of subacute acidosis (commonly seen in fattening cattle fed with high-precision feed), the rumen pH is maintained within the ideal range of 6.2-6.8.

2. Enhance immune function
      Immune factor activation: β-1, 3/1,6-glucan can activate macrophages and dendritic cells, and increase serum IgG and IgA levels by 20% -30%, especially in calf stage, it can reduce the incidence of diarrhea by 15% -25%.

      Antioxidant support: The presence of glutathione precursor substances (such as cysteine) can increase the activity of superoxide dismutase (SOD), reduce the content of lipid peroxidation product MDA, and alleviate oxidative damage caused by heat stress.

3. Improve production performance
      Milk production of cows: Experimental data shows that adding 0.3% -0.5% yeast hydrolysate to the diet of lactating cows can increase milk production by 1.5-2.5kg/day and increase milk protein content by 0.1-0.15 percentage points.

      Benefits of beef cattle weight gain: In the fattening experiment, the daily weight gain increased by 8% -12%, the feed to meat ratio decreased by 5% -8%, and the time for each cow to be slaughtered was shortened by 10-15 days, significantly improving economic benefits.

4. Relieve stress reactions
      Heat stress regulation: By regulating the expression of HSP70 (heat shock protein), cortisol levels are reduced by 15% -20%, and feed intake is maintained at a reduction rate of no more than 10% in high-temperature environments (the untreated group usually decreases by 20% -30%).

      Transportation/Transit Stress: Supplementing yeast hydrolysate can reduce serum creatine kinase (CK) and cortisol concentrations, maintain lymphocyte transformation rate, and reduce the incidence of respiratory diseases after transportation.

5. Improve reproductive performance
      Application of breeding cows: Improve conception rate by 8% -12% and shorten the interval between the first estrus after delivery by 5-7 days. The mechanism may be related to improving energy negative balance (by increasing NEFA utilization) and regulating the secretion of reproductive hormones such as progesterone and estradiol.

6. Potential for replacing antibiotics
      Pathogen inhibition: Mannan oligosaccharides can competitively bind to pili receptors of Salmonella and Escherichia coli, reducing intestinal colonization. The experiment showed that the number of Escherichia coli in the intestinal tract of calves decreased by 1-2 logarithmic orders of magnitude after addition, while the number of lactic acid bacteria increased by 2-3 times.

Usage suggestions and precautions:
      Addition amount: It is usually recommended to add 0.1% -0.3% (dry matter basis) to the diet, which needs to be adjusted according to the growth stage of the cattle (calf, fattening cattle, lactating cattle).

      Cost effectiveness: Based on current market prices, the cost of full price materials per ton increases by about 30-50 yuan, but improving production performance can bring 2-3 times the economic return.

      Compatibility synergy: When combined with probiotics (such as Bacillus subtilis) and organic trace elements (such as selenomethionine), it can produce a synergistic effect and enhance overall effectiveness.

Empirical case:
      A certain large-scale ranch added 0.2% yeast hydrolysate to the diet of lactating cows, and after 3 months:

      The average daily milk production has increased from 29.5kg to 31.2kg (+5.8%)

      The number of somatic cells decreased from 250000/mL to 180000/mL (-28%)

      The incidence of hoof disease has decreased by 40%, and the annual elimination rate has decreased by 2.3 percentage points.

      In summary, yeast hydrolysates have significant value in improving breeding efficiency and ensuring the health of cattle herds through a multi-target mechanism, especially suitable for modern pasture applications under intensive and high production pressure. In practical use, it is necessary to combine the specific situation of the ranch and optimize the addition plan through phased effect evaluation.
