Yeast cell wall is mainly composed of glucan, mannose oligosaccharide and protein, etc. It has the functions of enhancing immunity, promoting growth, anti-tumor, and adsorbing mycotoxins. However, it has poor solubility, unsatisfactory direct use effect in animal breeding process. Therefore, modifying the yeast cell wall to improve the solubility of the yeast cell wall has positive significance for the application and promotion of the yeast cell wall in animal feeding.
1. What is YeaMOS S
YeaMOS S is produced by the complete hydrolysis and extraction of Saccharomyces cerevisiae cell wall with specific enzymes. It contains 40% mannose oligosaccharide, and the dissolution rate exceeds 90% which can be auditioned by watering system. The dosage in water should be calculated according to the amount of feed and water intake. The main ingredient mannose oligosaccharide can help for the intestine health by binding mycotoxins and blocking the pathogenic bacterials. What’s more, mannose oligosaccharide as a kind of prebiotic, which can be selective fermented by lactobacillus, bifidobacteria, help for the beneficial bacteria proliferate in the posterior segment of the intestine, then regulate the intestine flora and enhance the health and growth performance for animals.
2. Application of YeaMOS S in animal production
2.1 YeaMOS S can stabilize egg production rate and immune level of laying hens
Fig. 1 Effects of YeaMOS S on production performance and immunity of laying hens
A total of 540 47-week-old Hylan gray laying hens were randomly divided into two treatment groups, the control group and the test group. The control group was fed basal diet (corn soybean meal type) + tap water. The test group was fed the basal diet + tap water with 0.3 g/L YeaMOS S, and the experimental period was 30 days. The results showed that adding 0.3 g/L YeaMOS S to the drinking water of laying hens could stabilize the laying hen's egg production rate and improve its specific immunity level.
2.2 YeaMOS S can increase the slaughter weight and reduce the feed to meat ratio of broilers
Fig. 2 Effects of YeaMOS S on body weight of white-feathered broilers (kg)
Fig. 3 Effect of YeaMOS S on feed to meat ratio of white feather broilers during the test
About 60,000 white feather broilers of 1-day-old age and basically the same body weight were selected and randomly divided into 2 treatment groups, all of which were fed commercial broiler diets. During the test period, the drinking water of the broilers in the control group was tap water, and the drinking water of the test group was supplemented with 300g/t YeaMOS S, and the test period was 45 days. The results showed that adding 300g/t YeaMOS S to the drinking water of white feather broilers could increase the slaughter weight of broilers and reduce the ratio of feed to meat, and the input-output ratio was 1:6.
2.3 YeaMOS S can reduce mortality and improve growth performance of Cherry Valley ducks
Tab. 1 Effects of YeaMOS S on the growth performance of Cherry Valley ducks
About 20,000 Cherry Valley ducks with basically the same body weight were selected and randomly divided into 2 treatment groups, all of which were fed commercial diets. During the test period, the drinking water of the broilers in the control group was tap water, and the drinking water of the test group was supplemented with 200g/t YeaMOS S, and the test period was 20 days. The results showed that compared with the control group, the death rate of the test group decreased by 30.67% (0.52% vs. 0.75%), and the average weight of a single duck increased by 1.32% (198.75g vs. 196.17g), the feed ratio is reduced by 0.01 (1.56 vs. 1.57). And from customer feedback, the feed intake of the test group decreased by 3.13% in the first 10 days, and the feed intake increased rapidly in the next 10 days, which was an increase of 0.65% compared with the control group, and the degree of fecal formation was significantly improved, the dead scouring decreased, and the weight gain increased, which shows that YeaMOS S can effectively improve the health of cherry valley ducks, reduce dead scouring, and promote growth performance.
3. Conclusion
Combined with the above test results, it can be seen that adding YeaMOS S in animal drinking water can improve the growth performance and immunity of animals and maintain the health of animals.
4. Recommendation for animals
Feed enterprise：Piglet: 200-300g/t; Sow: 200-300g/t; Poultry: 200g/t;
Farm：Swine: 0.5~1kg/t water or feed for 3~5d;
Poultry (especially layer): 300~500g/t water or feed;
(Double dose if under strong stress condition)
