| With in-depth knowledge of feed safety issues, the choice of feed additives has become a hot topic. Lactic acid bacteria can regulate animal intestinal flora balance, thereby improving the digestibility of animal food, and could reduce the cholesterol in animal products; In addition, Chinese medicine Monascus synbiotic is a green security feed additives.This test uses 216 (400-day-old) weight uniformity, egg production was similar, healthy body condition navy brown laying hens were randomly divided into three groups, each set three replicates of 24 chickens were in the control group, group 1 and group 2. Test is divided into two stages, namely the pre-trial period seven days,49 days trial period. During the test to ensure adequate lighting, clean water and clean the house. Determination of picking up eggs once a day after the official start of the test, and record the number of each repetition group test eggs, laying hens weight and the number of deaths, three days before the end of the trial using total feces collection method determine chicken nutrient digestibility, and record daily feeding amount, the remaining quantity. 48h after collecting chicken feces test for determining nutrient content, calculated layer ration dry matter, crude protein, organic matter, calcium, phosphorus digestibility. Test results were as follows:(1) In terms of production performance:Lactobacillus-Monascus medicine mix additive has a very good improvement of production performance of laying hens, can significantly improve the laying rate, while significantly reducing egg laying hens feed ratio.(2) In terms of egg quality:Lactic acid bacteria-Monascus medicine mixed additive Monascus also increased average egg weight. Monascus medicine BIOSTIME group can significantly improve the conventional indicators eggs. Lactic acid bacteria-Monascus medicine mixed additive significantly improves the Haugh units, eggshell thickness, improve eggshell redness, also can significantly improved yellowness. Two experimental groups can improve the eggshell brightness(3) Egg nutrition aspects:Lactic acid bacteria-ruber ruber Chinese medicine mixing additives and additive BIOSTIME have a good influence on the content of various nutrients in the egg yolk, and lactic acid bacteria-mixing additive Monascus best medicine.(4) Nutrient digestibility in laying hens:the lactic acid bacteria-Monascus Chinese apparent mix additive for laying hens each nutrient digestibility were significantly improved.(5) In terms of storage:lactic acid-a mixed group of additives monascus medicine and traditional Chinese medicine Monascus synbiotic group were positive role in enhancing the egg storage time aspect, but there was no significant difference in coefficient yolk.(6) In the oxidation resistance:lactic acid-a mixed group of additives monascus medicine and traditional Chinese medicine Monascus synbiotic group to improve the oxidation resistance of egg yolk, both have positive effects.The above test results show that the combination of both the production performance of laying hens are improved, Monascus medicine synbiotic combinations can enhance the quality of conventional eggs, and lactic acid bacteria-adding a combination of traditional Chinese medicine Monascus mix egg storage time and antioxidant activity of more help. |
