Application of Longli Xylo-oligosaccharide in Layer Chicken Feed

China has become a big country in the feed industry with an annual output of about 70 million tons of feed. With the improvement of living standards and the strengthening of health awareness, people have a better understanding of the problem of "adventuring from the mouth." In recent years, non-polluting, non-residual and pollution-free safe green foods have become a kind of consumer fashion, and feed additives are one of the main causes of harmful substances residues. Therefore, the research and production of pollution-free feed additives have been applied in China's feed industry in recent years. The industry set off a boom. The development and application of new, high-efficiency, and pollution-free feed additives that have both disease-prevention and disease-resistance capabilities, but also can significantly increase the aquaculture production and quality, will enable China's feed science and technology and aquaculture to a new level.

Xylo-oligosaccharide, as a novel oligosaccharide additive, is one of the better products of the oligosaccharides with better function of proliferating Bifidobacterium, inhibiting the growth of pathogens and spoilage substances, and purifying the intestinal tract.

The characteristics of xylo-oligosaccharides

Xylo-oligosaccharides, a novel type of oligosaccharide additive, is a low-degree polymerization of two to seven xylose linked by β-1,4 glycosidic bonds extracted from xylan-rich natural plants. The general name of sugar.

Experimental report on the application of xylo-oligosaccharide in layer chicken feed

Effect of Xylo-oligosaccharides on Production Performance of Laying Hens. Studies have found that xylo-oligosaccharides can affect the performance of laying hens. The results showed that the addition of 0.015% and 0.02% Xylo-oligosaccharides to the diet significantly increased the average daily egg production rate, egg production weight, and feed conversion rate (P).

The study found that 0.015% of xylo-oligosaccharides were the appropriate dosage, which could significantly increase the egg production rate of laying hens, and the increase rate was about 6.85%; the ratio of eggs to eggs was decreased by 6.45%; the percentage of egg yolks in the whole eggs was increased by 3.27% compared with the control group. The egg shell thickness decreased by 4.65% compared with the control group, and the decrease was significant. At the same time, there was no effect on the egg quality; the gross profit increased by 23.9%.

Effects of Xylo-oligosaccharides and Synbiotics on Production Performance of Laying Hens. According to the study, the average egg laying rate in the experimental groups increased by 4.09%, 6.81%, 3.71%, and 4.85%, respectively, and the average egg quality increased by 1.79%, 3.02%, 2.41%, and 1.28%, respectively. Increased 6.79%, 10.63%, 6.04%, and 6.70%, and the ratio of eggs to eggs decreased by 6.25%, 9.38%, 5.47%, and 6.25%, respectively. The addition of 0.01% xylo-oligosaccharide + 0.005% prebiotics is a good combination of the indicators.

summary

The chicken raising industry is one of the pillar industries in rural areas and agriculture in China. Due to the high density of chickens in chicken farms, poor ventilation, light conditions, fecal odor, and serious air pollution cause chicken indigestion, loss of appetite, and the spread of various diseases. This not only affects the feed utilization rate, meat production rate and egg production rate, but also significantly increases the cost of chicken drugs, seriously affecting product quality.

Adding a certain amount of Xylo-oligosaccharides to the feed can increase the egg production rate to a certain extent, reduce the material-to-egg ratio, increase the color and quality of eggs, improve the maintenance and management environment, and have good social and economic benefits. In addition, xylo-oligosaccharide is a natural feed additive, which has the advantages of no pollution and no residue. Therefore, in the feed industry, xylo-oligosaccharides have a broad application prospect as an excellent green additive.
