The effect of yeast hydrolysate on the growth performance of piglets

      The impact of yeast hydrolysate on the growth performance of piglets is mainly reflected in four dimensions: "improving growth rate, optimizing feed utilization, ensuring quality of life, and improving population uniformity", and these impacts are directly related to breeding benefits (cost reduction and efficiency improvement). Its function is not driven by a single factor, but by improving the physiological basis of piglet digestion and absorption, intestinal health, immune status, etc., ultimately transforming into quantifiable growth performance indicators, as follows:

1、 Significant increase in daily weight gain (ADG): accelerates weight gain and shortens the fattening cycle

      Daily weight gain is a core indicator for measuring the growth rate of piglets, and yeast hydrolysate improves daily weight gain through a dual pathway of "nutrient efficient supply+reduced growth interference":

Impact performance:

      The daily weight gain of piglets (especially 1-4 weeks after weaning) can be increased by 8% -15%. For example, the daily weight gain of ordinary weaned piglets (15-30 days old) is usually 200-220g, which can reach 216-253g after adding yeast hydrolysate; in the early stage of fattening (30-60 days old), the daily weight gain can be increased from 280-320g to 300-368g.

Mechanism of action:

      Fast absorption of nutrients: Small molecule peptides (<1000Da) are directly absorbed by the intestine without digestion, quickly supplementing amino acids and avoiding growth arrest caused by "nutritional gaps" after weaning;

      Reduce disease interference: Yeast polysaccharides (glucans) activate immune cells, nucleotides repair intestinal mucosa, and reduce the incidence of diarrhea and respiratory diseases - diseases can lead to "compensatory depletion" of piglets (energy is used for disease resistance rather than growth), significantly improving growth efficiency under healthy conditions;

      Metabolic efficiency optimization: B vitamins (B1, B2, niacin) act as energy metabolism coenzymes, promoting the conversion of carbohydrates and fats in feed into the energy needed for growth, reducing metabolic waste caused by "eating too much and growing slowly".

2、 Reduce Feed to Meat Ratio (FCR): Optimize feed utilization and reduce breeding costs

      The feed to meat ratio ("feed consumption/weight gain") directly reflects the cost of feed, and yeast hydrolysate reduces the feed to meat ratio by "improving digestion efficiency+reducing nutrient waste", which is the key to cost reduction for farmers

Impact performance:

      The feed to meat ratio of piglets can be improved by 0.05-0.1 throughout the process. For example, the feed to meat ratio of ordinary piglets from weaning to 30kg body weight is about 1.8-2.0, which can be reduced to 1.7-1.9 after adding yeast hydrolysate; This means that for every 30kg piglet raised, feed consumption can be reduced by 1.5-3kg (calculated based on improvement of 0.05-0.1).

Mechanism of action:

      Enhance digestive ability: Yeast hydrolysate can activate trypsin and amylase activity in piglet intestines (increase by 10% -15%), promote the decomposition of crude protein and starch in feed, and reduce the waste of "undigested nutrients excreted with feces";

      Reduce intestinal disorders: Mannooligosaccharides inhibit Escherichia coli and Salmonella, prevent harmful bacteria from decomposing nutrients and producing toxins (such as endotoxins), and reduce nutrient absorption disorders caused by intestinal inflammation;

      Substitution of high priced raw materials: Small molecule peptides from yeast hydrolysates can partially replace high priced protein sources such as whey powder and fish meal (substitution rate of 5% -10%), further reducing feed formulation costs without affecting growth.

3、 Improve feed intake: alleviate "weaning refusal" and ensure basic nutrient intake

      After weaning, piglets are prone to a sudden drop in feed intake (a decrease of 30% -50%) due to "environmental stress+changes in feed palatability". Feed intake is the "basic prerequisite" for growth, and yeast hydrolysate can effectively improve this problem:

Impact performance:

      The recovery time of feed intake for weaned piglets is shortened by 1-2 days, and the average daily feed intake within one week after weaning can be increased by 10% -15% (from 180-200g/head/day to 200-230g/head/day).

Mechanism of action:

      Relieve feeding inhibition caused by stress: Yeast hydrolysate reduces the concentration of cortisol (stress hormone) in piglets (by 20% -25%), alleviating "stress-induced anorexia";

      Improving feed palatability: Yeast hydrolysate contains natural flavor substances (such as nucleotides and organic acids), which can improve the flavor of compound feed, stimulate piglet taste and smell, and promote feeding;

      Relieve intestinal discomfort: After intestinal mucosal repair, piglets' feeding resistance caused by "intestinal pain" (such as inflammation and bloating) is reduced, and their active feeding intake is increased.

4、 Improve survival rate: reduce deaths from "weaning syndrome" and ensure breeding profits

      The mortality rate of piglets during weaning due to "diarrhea and secondary infection" can reach 5% -10%. Although the survival rate does not directly belong to the "growth rate" indicator, it is a "prerequisite guarantee" for growth performance (dead piglets have no growth benefits):

Impact performance:

      The survival rate of weaned piglets can be increased by 5% -8%, especially in stress environments such as high temperatures in summer and cold winters, where the increase in survival rate is more significant (up to 10% or more); At the same time, the proportion of "stiff pigs" caused by diseases has decreased by 15% -20% (stiff pigs have stagnant growth and no breeding value).

Mechanism of action:

      Reduce diarrhea induced mortality: By inhibiting harmful bacteria (reducing Escherichia coli by 30% -40%) and repairing mucous membranes (increasing intestinal villus height by 10% -15%), the weaning stress diarrhea rate can be reduced from 30% -45% to 10% -20%, avoiding dehydration and exhaustion caused by diarrhea;

      Enhance disease resistance: β - glucan activates macrophage phagocytosis efficiency (increasing by 25% -30%), nucleotides promote antibody production (such as increasing the antibody titer of swine fever vaccine by 1-2 titers), reducing the risk of mortality from diseases such as circovirus and paratyphoid fever;

      Improving stress resistance: Yeast hydrolysate can stabilize the physiological state of piglets and reduce "stress induced sudden death" or "secondary infection death after stress" in stress scenarios such as transportation, herd rotation, and sudden temperature changes.

5、 Improve group neatness: reduce individual differences, facilitate unified management and slaughter

      The neatness of the group is an important indicator of the management efficiency of farmers (uneven size can lead to "strong people grabbing food and weak people stopping growing"), and yeast hydrolysate can reduce individual growth differences in piglets:

Impact performance:

      The coefficient of variation of body weight in piglet populations (reflecting individual differences) can be reduced by 15% -20%. For example, in the general weaned piglet population, individuals with a weight difference of more than 2kg account for about 30%, and the addition of yeast hydrolysate can reduce it to 15% -20%; At the time of final slaughter, over 80% of piglets' weight can be concentrated within the target range (such as 110-120kg).

Mechanism of action:

      More balanced nutrient absorption: The "indiscriminate absorption" characteristic of small molecule peptides avoids "uneven nutrient distribution" caused by individual differences in digestive ability (weak pigs can also efficiently absorb nutrients);

      The stress effect is more uniform: yeast hydrolysate has a stress relieving effect that covers the entire population, reducing the differences in "partial pig growth arrest and partial pig normal growth" caused by individual stress tolerance differences;

      More consistent health status: The role of intestinal health and immune enhancement can reduce "individual differences in disease incidence probability" and avoid growth lag caused by some pigs being infected.

      Summary: The core value of yeast hydrolysate on piglet growth performance

      The impact of yeast hydrolysate on piglet growth performance is essentially an upgrade from 'barely surviving' to 'healthy and efficient growth' - not only solving the problem of 'surviving' during weaning (improving survival rate), but also addressing the core demand for 'fast growth, good growth, and low cost' (increasing daily weight gain, reducing feed to meat ratio, and improving neatness).
