What is the effect of the addition ratio of yeast hydrolysate on the growth

The addition ratio of yeast hydrolysate varies, and it will have different degrees of impact on the growth performance of chickens, as follows:

Chick stage

      Low addition ratio (such as around 0.1% -0.3%): It can provide some easily absorbable nutrients for chicks, such as small peptides, amino acids, etc., which help with the initial development of the digestive system of chicks, stimulate the growth of intestinal villi, improve the absorption capacity of nutrients in the intestine, ensure that chicks have a good start, make their growth more stable, and to some extent improve the early survival rate of chicks. However, due to the relatively small amount added, the effect on promoting rapid weight gain may not be significant.

      Moderate addition ratio (about 0.3% -0.5%): In addition to further improving intestinal function, it can also meet the nutritional needs of chicks for various essential amino acids, nucleotides, and other nutrients, enhance their immunity, help chicks better resist the invasion of external pathogens, and reduce the occurrence of diseases. At the same time, this ratio can improve the palatability of the feed, stimulate the feeding of chicks, enable them to consume more sufficient nutrients, and promote steady weight growth of chicks, laying a solid foundation for subsequent breeding stages.

      Excessive addition ratio (over 0.5%): It may disrupt the microecological balance in the intestines of chicks, as excessive nutrients cannot be digested and absorbed in a timely manner, causing a burden in the intestines and disrupting the gut microbiota, leading to digestive problems such as diarrhea, which is not conducive to the growth of chicks, and may even result in slow growth and weakened physical condition.

Chicken breeding stage

      Lower addition ratio (0.2% -0.4%): Helps maintain the intestinal health of broiler chickens. The intestinal function of broiler chickens is constantly improving, and yeast hydrolysate can provide continuous nutritional support, ensuring the growth of beneficial bacteria in the intestine, inhibiting harmful bacteria, and reducing the risk of intestinal diseases. However, the promotion effect on weight gain and bone development is relatively limited, and the growth rate of broiler chickens may be at the lower limit of normal levels.

      Moderate addition ratio (0.4% -0.6%): It can provide sufficient protein, vitamins, and other nutrients for breeding chickens, promote their good development of bones and muscles, increase their weight at a reasonable rate, make their body more symmetrical, and also enhance their immune system, making them stronger during the transition to adulthood, improving their adaptability to the egg laying or fattening period, and optimizing their overall growth performance.

      Excessive addition ratio (over 0.6%): It can also easily cause nutrient excess, increase the digestive burden of breeding chickens, lead to a decrease in feed conversion rate, and excess nutrients may also accumulate abnormally in the body, affecting the metabolism of breeding chickens. Not only does it waste feed costs, but it may also cause problems such as growth stagnation and poor health conditions in breeding chickens.

Egg laying stage

      Lower addition ratio (0.3% -0.5%): It can improve the intestinal environment of laying hens to a certain extent, enhance the absorption capacity of calcium, phosphorus and other minerals and nutrients in the intestine, and is beneficial for maintaining the basic health status of laying hens. It can keep the egg production rate of laying hens at a relatively stable but not high level, and the quality of eggs can also maintain basic standards, such as eggshell quality and yolk color, which are in a normal state.

      Moderate addition ratio (0.5% -0.8%): Helps improve the egg laying performance of laying hens, stimulate the reproductive system function of laying hens, significantly increase the egg laying rate, prolong the peak egg laying period, and significantly improve the quality of the eggs produced. The egg weight increases, the eggshell becomes stronger and smoother, the egg breakage rate decreases, and the nutritional content of the yolk is richer. At the same time, the physical fitness and disease resistance of laying hens can also be enhanced, reducing the risk of fluctuations in egg production caused by diseases.

      Excessive addition ratio (over 0.8%): It may cause nutritional metabolism disorders in laying hens, such as adverse effects on calcium and phosphorus metabolism balance, which in turn affects the formation of eggshells and leads to quality problems such as an increase in thin shell and soft shell eggs. Moreover, excessive addition may increase the burden on organs such as the liver and kidneys of laying hens, affecting their overall health and ultimately resulting in decreased egg production performance.

Broiler stage

      Lower addition ratio (0.5% -1%): It can improve the palatability of the feed, make broiler chickens more active in feeding, and help maintain the intestinal health of broiler chickens. It can also improve the digestion rate of the feed to a certain extent, allowing broiler chickens to obtain more nutrients from the feed and promote weight gain. However, the effect is relatively less prominent, and the slaughter time may be slightly longer. The final weight and feed to meat ratio are at normal levels.

      Moderate addition ratio (1% -1.5%): It can fully utilize the advantages of yeast hydrolysate, provide rich amino acids, small peptides and other nutrients for broiler chickens, accelerate muscle growth, improve feed conversion rate, accelerate weight growth, significantly shorten slaughter time, optimize feed to meat ratio, significantly improve breeding efficiency, and also enhance the disease resistance of broiler chickens, reducing the incidence of diseases during the breeding process.

      Excessive addition ratio (over 1.5%): It can cause excessive nutrition in the intestinal tract of broiler chickens, damage the intestinal microbiota, lead to digestive and absorption dysfunction, and result in over feeding (undigested feed in feces), reducing feed utilization efficiency. At the same time, it may also cause intestinal diseases in broiler chickens, affecting their growth rate and health status, and damaging breeding efficiency.

      In short, the addition ratio of yeast hydrolysate needs to be precisely controlled according to the different growth stages of chickens. The appropriate ratio can effectively improve the growth performance of chickens, and too high or too low may have adverse effects.
