Description

Jinling chicken feed taking purple elephant grass, alfalfa and kudzu as main materials and preparation method thereof
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of chicken feeds, in particular to a Jinling flower chicken feed taking purple elephant grass, alfalfa and kudzu as main materials and a preparation method thereof.
[ background of the invention ]
The modern large-scale animal husbandry feeding mode improves the production speed and brings many problems, the quality of animal products is reduced, various diseases are easy to occur to livestock and poultry, and the harm to the health of human beings caused by adding a large amount of antibiotic medicines and additives in the feed affects the healthy development of animal husbandry in China. The high-quality feed is a guarantee for producing high-quality livestock products, and at present, the quality and quality of the livestock and poultry products are urgently needed to be improved in China, and the feed is beneficial to the healthy growth of animals and beneficial and harmless to the health of consumers. China has a lot of plant resources, contains a lot of active substances and nutrient components, has very high medicinal value and special functions, reasonably selects, develops and utilizes the plants, extracts beneficial components and adds the beneficial components into feed, and is an effective way for improving the production performance of livestock and poultry, ensuring the safety of livestock products and producing high-quality feed.
The Jinling spotted chicken is characterized in that: the whole cock has the advantages of red and numb feather, Chinese ephedra feather, fast growth, plump breast muscle, high economic benefit and fast fund returning. The disadvantages are low laying rate, low protein content and shell hardness of the eggs, and high fat and cholesterol content in the eggs.
The purple elephant grass likes warm and humid climate, has wide adaptability, and can be planted in tropical and subtropical areas with elevation below 1000m and annual precipitation above 700 mm. The leaves can live through the winter in southwest area, and the leaves can wither in northwest area, but the underground part can safely live through the winter. The method has the advantages of strong adaptability, fast growth, good reproducibility, high yield of the fresh hay, fertilizer resistance, drought resistance, acid resistance, strong lodging resistance, capability of being used for 10-15 years after 1 planting and low planting cost. However, the purple elephant grass has low protein content and high crude fiber content, and the single use of the purple elephant grass cannot meet the requirement of the chicken on protein nutrition.
The alfalfa belongs to perennial leguminous plants, has high protein content, rich nutrition and wide application, is widely planted in China, can be mixed into the daily ration of laying poultry to deepen the color, can improve the fertility when being fed to the laying poultry, can increase the skin pigmentation when being fed to broilers, and has large utilization space. Meanwhile, because the market price of the alfalfa is high, the excessive use of the alfalfa also increases the feeding cost. Currently, alfalfa is used primarily for the preparation of hay bales or pieces. But the soluble sugar content of the alfalfa is too low, and the sugar content of the alfalfa is only 3.72 percent; the alfalfa is rich in saponin, wherein the saponin is an anti-nutritional factor, and can inhibit rumen microbial fermentation and inhibit the digestion of nutrient substances in the digestive tract; animals often suffer from rumen expansion when eating a large amount of alfalfa at one time, and the normal digestive function of rumen is further influenced. Therefore, in the actual cultivation production, the single use of the alfalfa not only increases the feeding cost, but also the anti-nutritional factor saponin contained in the alfalfa is not beneficial to the digestion and absorption of the nutrient substances.
Pueraria lobata, also known as Pueraria lobata and Pueraria thomsonii, is a perennial Pueraria plant belonging to the family Leguminosae, and has 17 species in China, with the exception of Tibet and Xinjiang provinces. The growth of the kudzu has low requirement on environmental conditions, is barren-resistant, cold-resistant and drought-resistant, and the flowers and the root tubers of the kudzu are rich in nutrient substances and can be eaten and used for medicine; the tender stem and leaf of kudzu vine have good palatability and are excellent feed sources. According to the authority experts of the organizations such as the world food and agriculture organization, the kudzu is expected to become the sixth food crop in the 21 st century (Zhang Yuan, 2007). Protein forage grass is lacked in summer and autumn in south China, high-quality forage grass is unbalanced in supply time, kudzu serves as forage grass with high protein content, rattans grow vigorously, and green feed can be provided all the year round. However, at present, people have less research on the kudzu as a feed crop, so that the improvement of the research on the feeding characteristics of the kudzu and the enhancement of the importance on the feeding value of the kudzu can help to promote the development of the animal husbandry in China.
At present, no report exists for feeding Jinling chicken by comprehensively utilizing purple elephant grass, alfalfa and kudzu.
