The types of feed and its nutritional characteristics

2024-07-25

Roughage mainly has a variety of hay, a variety of crop straw and a variety of branches, leaves and so on. The main characteristics of this feed are: 1. All contain a lot of cellulose, palatability is poor. It can stimulate the peristalsis and development of digestive organs. Large volume, full feeling. 2. Low content of various nutrients.

What are the types of feed materials?

(1) Energy feed refers to the dry matter crude fiber content is less than 18%, while the crude protein content is less than 20% of grain, bran, grass seed and tree fruit, starch roots, tubers and melons and vegetables and other feeds. Common energy feeds are: (1) Corn: crude protein content of 8%~9%, digestive energy 14.27 MJ/kg, the kernel contains very rich starch, crude fat content is also high, is an important high energy concentrate. But lack of lysine, methionine and tryptophan three essential amino acids. In the world feed cereals (corn, barley, oats, sorghum, rice) accounted for about 50% of the total feed cereals. ② Wheat: protein content and quality are higher than corn, energy is close to corn, palatability is better than corn, growth and fattening pig use, can reduce yellow fat, improve pork quality. General crude protein 13.9%, digestive energy 14.18 MJ/kg. Compared with corn, wheat protein and vitamin content is higher, but the content and utilization of biotin is low, as the main raw material to replace corn should pay attention to supplement biotin, wheat also lacks lysine, should be properly supplemented. Wheat contains anti-nutrition factors pentosan, phytic acid phosphorus and so on, pigs can not digest and absorb, excreted through feces, will pollute the environment. In addition, wheat is easily infected with gibberella, which can cause acute vomiting in pigs. For Suckling pigs, powder is generally good, and for large pigs, crushed grains are generally better, otherwise the palatability is poor. Rice bran: The mixture of seed coat, aleux layer and embryo separated when brown rice is processed into white rice, and its nutritional value varies according to the degree of white rice processing. Its dry matter contains 11.9% crude ash and 13.7% crude fiber, which is a disadvantage. However, containing 13.8% crude protein and 14.4% crude fat is its advantage, but the unsaturated fatty acid content in these crude fats is high, so it is not easy to store, easy to rancidity due to oxidation. At the same time, the ratio of calcium and phosphorus is not suitable, which is 1:22; Because it contains more oil, feeding animals too much, easy to cause diarrhea. It is generally controlled below 15%, and it is safer to choose processed degreased rice bran or use fresh rice bran. Wheat bran: is a by-product of wheat processing into flour, consisting of wheat seed coat, aleurone layer, a small amount of germ and endosperm. The quality and quantity of bran production depend on the processing process, and the crude fiber is as high as 8.5%~12.0%. The protein content is as high as 12.5%~17.0%, the quality is also higher than wheat, containing 0.67% lysine. However, the methionine content is very low, only 0.11%, the big drawback is the imbalance of calcium and phosphorus, which is 1:8, and special attention should be paid to calcium supplementation when matching the diet. The advantage of wheat bran is that the fluffiness can regulate the bulk weight of the feed, and the laxity can regulate the function of the digestive tract, but it should be noted that the wheat bran has strong water absorption and is easy to cause constipation.

The Ministry of Agriculture and Rural Affairs issued the Work Plan for 2024 Feed Quality and Safety Supervision

2024-07-25

In order to effectively strengthen feed quality and safety supervision, improve the quality and safety guarantee level of livestock products, and promote the high-quality development of animal husbandry, the Ministry has formulated the 2024 Feed Quality and Safety Supervision Work Plan in accordance with the Law of the People's Republic of China on the Quality and Safety of Agricultural Products and the Regulations on the Management of Feed and Feed Additives and other laws and regulations. It is now issued to you, please do a good job in accordance with the actual implementation.

China feed industry exhibition held

2024-07-25

Southeast Network April 20 news (Fujian Daily reporter Zhang Hui) 19, 2024 China feed industry exhibition opened in Xiamen City. With the theme of "Strong industry Response Bureau opens a new Bureau", the exhibition aims to build a comprehensive display, exchange and cooperation platform for the high-quality development of the feed industry. The exhibition attracted more than 600 enterprises to participate in the exhibition area of nearly 100,000 square meters, and the number of booths reached more than 3,000, which reached a record high. As the host, Fujian organized more than 50 local enterprises such as Tianma Technology Group, Shengnong Group and Haixin Group to participate in the exhibition. Among them, Fujian Tianma Technology Group Co., Ltd. focuses on its strategic layout in the whole industry chain of fishery and animal husbandry, animal husbandry, health food industry, intelligent breeding, high-quality provenance and international trade. The company's independent research and development and production of fish and livestock feed, covering the whole process from seedlings to formation. Core products eel compound feed production and sales worldwide, special aquatic feed production capacity worldwide, abalone, large yellow croaker, grouper compound feed nationwide. The reporter learned from the exhibition that Fujian has always taken feed production as an important basis for the development of modern aquaculture, vigorously adjusted and optimized the feed formula structure, actively developed high-quality feed resources, and cultivated group leading enterprises. At present, Fujian feed industry has entered the ranks of 10 million tons of provinces, with the country's only annual output of more than one million tons of feed processing plant, the number of feed industry listed enterprises in the forefront of the country, the first to establish feed production enterprises safety risk level control system. During the exhibition, nearly 20 innovative enterprises from all over the country released new products and technologies in the field of feed on site. The 2nd Biological Feed Innovation and Development Forum, the 6th silage Quality Tasting Competition, Feed and livestock product Testing Technology and Equipment Innovation Forum, 2024 Grain and oil Feed Industry Conference and other activities were held at the same time.
