Cattle and sheep compound nutrition licking block feed can be industrialized production

OA show ('918 '); [cattle and sheep compound nutrition Lick Block feed can be industrialized production] cattle and sheep compound nutrition Lick Block is a new type of feed additive product designed according to the physiological characteristics of cattle and sheep, which can be widely used in cattle, sheep, deer and other ruminants to supplement the lack of minerals, protein, energy, vitamins and other nutrients It has been 30 or 40 years since the application of compound nutrition Lick Block in ruminant feeding in developed countries In the past ten years, a series of researches on the production and application technology of compound nutritive licking block of cattle and sheep have been carried out by animal husbandry scientists in China, and a number of valuable scientific research results have been obtained However, no breakthrough has been made in the industrialized production technology of licking block At the same time, the quality of licking block is poor, such as low molding rate, soft texture, moisture absorption, expansion, etc., which is difficult to meet the feeding requirements of cattle and sheep As a result, this scientific research achievement with good feeding effect and broad application prospect has not been widely applied in the production of cattle and sheep in China In view of the above situation, Meng Qingxiang, Ph.D., School of animal science and technology, China Agricultural University, organized the technical force of relevant domestic universities and scientific research institutes, with the support of the national feed Work Office of the Ministry of agriculture, and through the selection of main equipment, the development of special equipment and a large number of tests, finally made a breakthrough in the industrialized production technology of cattle and sheep compound nutrition Lick Block The industrial production technology of Lick Block mainly includes crushing, batching, mixing, stacking and tempering, pressing, thermoplastic packaging, curing and other technological processes This technology can not only reduce the investment of heating and tempering equipment, but also reduce the loss of vitamins and other nutrients in the licking block in the heating and tempering process The technology is applying for a national patent for technological invention The self-developed special pressing die has the characteristics of wide range of raw materials, adjustable weight and thickness, free disassembly of mandrel and maximum exhaust, which greatly improves the product quality The newly designed device for heating and spraying molasses solves the problem that molasses and other materials cannot be fully mixed The scientific formula of licking block feed designed according to the nutrient content of feed in different areas and the characteristics of different kinds of animals has the characteristics of strong pertinence and obvious feeding effect The process adopts mechanized continuous operation, and the actual production capacity reaches 0.4-0.6 T / h compared with the domestic advanced process, the efficiency is increased by more than 5 times The damage rate of Lick Block is less than 2%, the humidity resistance is more than 90%, the compressive strength is higher than 45 kg / cm2, and the molding rate is 100% The licking block had good palatability, and the average daily gain of fattening cattle and sheep increased by 10 to 50% after feeding, and the milk yield of dairy cows increased by 8 to 20%, and the incidence rate was significantly reduced The direct economic benefit for farmers is 1.25-17 thousand yuan per ton of licking block The project has signed technology transfer contracts with four enterprises nationwide, among which Zhongyuan feed factory in Suning County, Hebei Province has been completed and put into operation The project team has demonstrated and promoted 815 tons of licking blocks in Hebei, Inner Mongolia, Beijing and other provinces, cities and autonomous regions, with a total output value of 12.9576 million yuan and a profit tax of 530100 yuan There are 4.41 million dairy cows in China, most of which are fed in houses, and there are nutritional supplement problems such as energy, protein, minerals and vitamins If the technology of licking block is popularized in 5% of dairy cows in China, the annual milk output will be increased at least 67300 tons, and the direct economic benefit will reach 120 million yuan There are 116 million yellow cattle and improved cattle and 303 million sheep and goats in China Because of the traditional way of raising, the level of raising cattle and sheep is very low in rural areas and pastoral areas, and the phenomenon of nutritional deficiency is very common Combining the technology of compound nutrition licking block of cattle and sheep with the national straw animal husbandry demonstration project will increase the current production efficiency of cattle and sheep by at least 15% The industrialization production technology of cattle sheep compound nutrition licking block is the result of the "95" science and technology development project of the Ministry of agriculture, and the technology has been fully mature According to the expert appraisal organized by the Ministry of agriculture, the overall technology is leading in China The investment of single production line equipment for product production is less than 300000 yuan, and the annual single shift production of Lick Block is 1500 tons The "expert group of licking block development of the Ministry of agriculture", composed of experts and professors engaged in licking block production, cattle and sheep breeding, animal husbandry policy research from China Agricultural University and Chinese Academy of Agricultural Sciences, can provide "turnkey project" services for enterprises investing in licking block production China feed industry information network 8jl (author:)
