Description

Fungus chaff fermented feed applied to laying hen breeding
Technical Field
The invention belongs to the field of feed production and the field of laying hen breeding, and particularly relates to a mushroom bran fermented feed applied to laying hen breeding.
Background
The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
In recent years, the animal husbandry is facing the problems and changes of feed resource shortage, high dependence of corn-soybean meal type feed, comprehensive resistance prohibition and the like. Therefore, the development and utilization of new green feed resources are urgently needed under the new situation. The fermented fungus bran feed is a novel green biological feed which is not easy to fold and is capable of degrading cellulose, hemicellulose, lignin and the like which are difficult to utilize in fungus bran to different degrees through the fermentation effect of microorganisms and the decomposition effect of edible fungi, simultaneously generating a large amount of active substances, further improving the content of nutrient substances such as crude protein, saccharides and organic acids in the fungus bran and improving the sensory quality, and also improving the digestion utilization rate of animals. Therefore, the fungus chaff fermented feed is scientifically and reasonably developed, waste materials can be changed into valuable materials, resource waste and environmental pollution caused by a large amount of waste fungus chaff are reduced, the comprehensive development of the livestock husbandry, the family breeding and the agriculture in China can be promoted, the ecological effect is improved, and the economic benefit is improved.
However, because the fungus chaff contains high proportion of wood chips, cotton seed hulls, lignocellulose and the like, a single strain or a single strain can hardly achieve a good fermentation effect. Meanwhile, because the laying hens do not have enough endogenous lignocellulose degrading enzymes in the bodies, the digestion utilization rate of the fungus chaff fermented feed by the laying hens is still low, and the application of the fungus chaff fermented feed in the field of laying hen breeding is further influenced.
Disclosure of Invention
In order to solve the problem of low fermentation degree of the conventional fungus chaff fermented feed and expand the application of the fungus chaff fermented feed in animal breeding, the invention aims to provide the fungus chaff fermented feed with high fermentation degree and improve the feed quality.

drying, crushing and screening the fungus chaff of the flammulina velutipes, the pleurotus eryngii and the agaricus bisporus to filter impurities, then mixing according to the weight ratio, sterilizing at high pressure, and adjusting the water content to be 40-50% to obtain edible fungus chaff powder;
activating bacillus subtilis, lactobacillus acidophilus and candida utilis, and uniformly mixing according to the weight ratio to obtain a composite microbial inoculum;
fully stirring the edible fungus bran powder, the composite microbial inoculum, the enzyme preparation, the fermentation aid and the bran in proportion, uniformly mixing, tempering, and performing anaerobic sealed fermentation;
and spreading, airing and drying the fermented mushroom bran to finally obtain the mushroom bran fermented feed.
The third aspect of the invention provides a complete feed for laying hens in the laying period, which is prepared from the following raw materials in parts by weight: 50-60 parts of corn, 8-12 parts of soybean meal, 15-20 parts of any one of the fungus chaff fermented feed, 0.8-1.2 parts of soybean oil, 1.0-1.5 parts of calcium hydrophosphate, 6-10 parts of mountain flour and 1-5 parts of premix.
The fourth aspect of the invention provides a specific feeding method of complete feed for laying hens in the laying period, which comprises the steps of selecting laying hens with similar laying rates to feed into the same totally-enclosed laying hen house, and carrying out stacked cage culture; the illumination time is 15-16 h/d, the temperature in the house is 20-25 ℃, the relative humidity is 60-65%, and the ventilation is stable; automatically feeding, picking up eggs and cleaning manure, and freely drinking water and eating.
The invention has the beneficial effects that:
(1) according to the invention, flammulina velutipes, pleurotus eryngii and agaricus bisporus fungus chaff are used as main raw materials, and the fungus chaff fermented feed is prepared by adopting a mode of synergistic fermentation of bacillus subtilis, lactobacillus acidophilus, candida utilis composite microbial agents and enzyme preparations. The addition of the compound microbial inoculum can not only greatly improve the problems of insufficient fermentation degree, low feed digestion utilization rate and the like caused by a single strain, but also inhibit the propagation of harmful bacteria, improve the intestinal health and promote the growth and development of animals. In addition, the enzyme preparation can perform a synergistic effect with the composite microbial inoculum, so that the oxidative decomposition of the bad fermentation effect on sugar and protein and the content of fiber components are reduced while the lactic acid fermentation is promoted, and the fermentation process of fermented feed is accelerated. Finally, the fungus chaff fermented feed with rich nutrient components and higher digestion and utilization rate is prepared.
(2) The invention utilizes the fungus chaff fermented feed to replace partial soybean meal in basic ration of the laying hens, and prepares a complete feed applied to the laying hens in the egg producing period. The feed can improve the feeding environment of a henhouse, the production performance of laying hens and the egg quality while not changing or even reducing the feed cost, greatly improves the economic benefit, and can be widely applied to the breeding of the laying hens and other poultry.
(3) The operation method is simple, low in cost, universal and easy for large-scale production.
