The invention discloses a chicken feed probiotic agent containing enterococcus faecalis and a preparation method of the chicken feed probiotic agent. The chicken feed probiotic agent is prepared by virtue of the steps of evenly mixing enterococcus faecalis HEW-A131 active bacterial sludge, bacillus subtilis active bacterial sludge, saccharomyces cerevisiae active bacterial sludge and a stabilization protective agent together in the mass ratio of (0.1-0.8): (1-2.5): (0.1-0.5): 1, and then pelletizing, drying, coating and the like; the probiotic agent is capable of improving the utilization efficiency of an animal feed and saving the cost, and also capable of greatly improving the steady state of the internal environment of the digestive tract in an animal body, promoting the absorption and utilization of nutrition and promoting the growth of the animal; as a result, the productivity, the immune performance and the reproductive performance of the animal are obviously improved, the production cost is reduced and the economic benefit is increased.

The invention discloses a compound probiotic agent capable of improving the goose intestinal function and a preparation method thereof. The compound probiotic agent is prepared from a mixed bacteriumsolution and a compound carrier, wherein the mixed bacterium solution is a mixed bacterium solution of beles bacillus velezensis and enterococcocci; the compound carrier is a mixture of zeolite powderand rice chaff powder. The preparation method comprises the steps that the mixed bacterium solution and puffed corn powder are mixed, and are then mixed with the compound carrier. Compared with the prior art, the compound probiotic agent has the advantages that after being applied to a goose feed additive, the efficacies of helping the digestion, softening faeces and the like are achieved; the immune performance and the growth performance of geese can be improved; the compound probiotic agent is particularly applicable to the feeding of green geese with the incompletely developed intestinal function; the healthy green goose rate of the green geese is improved.

The invention discloses a feeding method capable of increasing hatching rate of hatching eggs of meat ducks. The feeding method comprises the following steps of: turning groups of the meat ducks at the age of 18 weeks; mixing groups of male and female ducks at the age of 20 weeks; adopting window opening type water-free dry feeding, wherein the feeding density is 3.6 ducks per square meter and the ratio of the male ducks to the female ducks is 1:4.8; illuminating for 17 hours every day; artificially feeding and picking up eggs; feeding with thick pad materials; and feeding each meat duck with200+ / -5 grams of mixed feed every day at the laying period of the meat ducks at the age of 28 to 75 weeks. The ducks are fed by the feeding method, the feed quantity of the meat ducks are controlled every day, and the methionine content, the lysine content, the vitamin E content, the niacin content and the biotin content of the mixed feed and the trace element selenium content are controlled, so that the average weight of the egg is controlled to be 90 to 92 grams, the egg quality meets the nutritional requirement and the laying rate, the healthy embryo development under the same hatching condition is benefited, the hatching rate and the healthy duckling rate are greatly increased, the quality of the newborn ducklings is improved, and the dead embryo rate of the hatching eggs is reduced.

The present invention discloses a feed micro-ecological preparation, an anti-nutritional substance-free feed and a preparation method thereof, and belongs to the technical field of feed. The feed micro-ecological preparation is prepared by fermenting the following raw materials in parts by weight: 1.0-1.2 parts of Saccharomyces cerevisiae, 0.2-0.6 part of Enterococcus faecalis, 1.5-2.0 parts of Bacillus subtilis, 0.2-0.6 part of Bacillus coagulans, 0.1-0.15 part of Bacillus licheniformis, 0.1-0.3 part of Bacillus lentus, 0.2-0.5 part of Clostridium butyricum and 993.05-995.15 parts of liquid medium. After the feed micro-ecological preparation is mixed with feed raw materials, enzymes produced in the process of microbial strain fermentation can decompose anti-nutritional substances in feed and increase the feed utilization rate; at the same time, microbial strains also have effects in improving animal intestinal environment, maintaining intestinal flora balance, inhibiting the growth of pathogenic bacteria, and improving animal immunity.

The invention discloses a feed additive for improving the reproductive performance of breeding ducks. The feed additive uses mineral-derived fulvic acid, bile acid, taurine, mineral zinc, compound enzymes, and probiotics as core raw materials, and uses zeolite powder as a carrier. The feed additive is directly added into the feed to feed the breeding ducks. It is proved by experiments that it can prolong the laying period, maintain a high laying rate and control the egg weight, thereby improving the reproductive performance of the breeding ducks.

The invention belongs to the technical field of feed, and in particular relates to a compound feed for layer breeder hens during the laying period which improves the healthy chick rate, and to a preparation method of the feed. The compound feed is mainly prepared from the following raw materials in parts by weight: 50-65 parts of cereals, 15-25 parts of soybean meal, 1-5 parts of corn gluten meal, 1-6 parts of rice bran meal, 2-6 parts of alfalfa powder, 1-3 parts of vegetable oil, 0.35-0.7 parts of amino acids, 0.05-0.1 parts of complex enzymes, 0.05-0.2 parts of prebiotics, 0.01-0.03 parts of 25-hydroxycholecalciferol, 0.01-0.3 parts of β-carotene, compound organic trace elements 0.03‑0.08 part, 1 part of compound premix. The sufficient and effective energy, amino acid, mineral nutrition and prebiotics of the present invention can ensure the requirement of maximum laying potential of layer breeder hens, high egg production rate and suitable egg weight, and high healthy chick rate of layer breeder hens.
