Diqing Tibetan pig fodder containing walnut cakes and preparation method of Diqing Tibetan pig fodder

Abstract

The invention discloses Diqing Tibetan pig fodder containing walnut cakes and a preparation method of the Diqing Tibetan pig fodder. The fodder is prepared from, by weight, 50.0-65.9 kg of corn, 9.0-23.0 kg of bean pulp, 2.0-9.0 kg of wheat bran, 2.0-22.9 kg of mixtures of rice chaff and husks, 0.5-8.0 kg of walnut cakes, 3.0 kg of fish meal and 4.0 kg of premixed materials. In order to solve theproblems that due to insufficient and unbalanced nutrients of existing Diqing Tibetan pig fodder, and especially insufficient protein, Diqing Tibetan pigs grow slowly, and local protein feed resourcesare quite scarce, on the basis of nutrition demand of the Diqing Tibetan pigs, the walnut cakes are utilized as protein feed raw materials, a series of formulas are provided to meet the nutrition demand of the Diqing Tibetan pigs in different physiology stages, and the growth speed of the Diqing Tibetan pigs is increased, and the fodder conversion efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of agriculture, animal husbandry and breeding, and specifically relates to a Diqing Tibetan pig feed containing walnut cake and a preparation method thereof. Background technique [0002] Diqing Tibetan pig is a unique high prototype pig breed in my country. It is formed after long-term selection and breeding under Diqing's high altitude geographical natural environment and alpine climate. It is an indispensable pig breed in the production and life of Tibetans. The plateau is characterized by a cold and low-oxygen climate and good meat quality. [0003] Because Diqing Tibetan pigs are distributed in plateau Tibetan areas, the climate is cold, and the transportation is inconvenient. The feed resources, especially protein feed resources, are scarce. The local directly uses single feed materials such as vine and highland barley to feed directly. The nutrition is unbalanced and cannot satisfy Diqing. The nutritional ne...

AI Technical Summary

Problems solved by technology

[0003] Since the distribution area of ​​Diqing Tibetan pigs belongs to the plateau Tibetan area, the climate is cold, the transportation is inconvenient, and the feed resources, especially the protein feed resources, are scarce. The locals directly use a single feed raw material such as turnip and highland barley to directly supplement the feed. The nutrition is unbalanced and cannot meet the needs of Diqing. The nutritional needs of growth of Qing Tibetan pigs lead to problems such as extremely slow growth (average daily gain of less than 200g) and low feed conversion rate of Diqing Tibetan pigs (more than 4.5 kg of feed per kg of weight gain), especially slow growth. One of the main bottlenecks restricting the improvement of Diqing Tibetan pig breeding efficiency, which restricts the improvement of Diqing Tibetan pig breeding efficiency

[0004] At present, there are the following deficiencies in the breeding feed of Diqing Tibetan pigs: adopt the mode of "breeding + supplementary feeding" to raise and supplementary feeding to the pigs with little nutrition, and the nutrition required for the growth of pigs is seriously insufficient; the feed raw materials (highland barley) , corn, oats) direct supplementary feeding, the nutrition provided to the pigs cannot be well digested and absorbed, resulting in the waste of some nutrients; the feed that pigs eat in the wild and the feed provided by supplementary feeding are all energy-based Mainly feed and green feed, lack of protein feed, unbalanced nutrition

[0005] In addition, the walnut industry is an advantageous industry in the development of plateau characteristic agriculture in Yunnan Province. According to preliminary statistics, in 2017, the walnut planting area in Yunnan Province was 43 million mu, and the output was about 1.15 million tons. The planting area, output and output value all ranked first in China. Shangri-La also has a large number of plantations. Moreover, because the local area is located on a plateau, the quality of walnuts is good. Now a large proportion of local farmers have harvested walnuts and pressed them for oil. The walnut cake after oil extraction is used as fertilizer or fuel, not as feed. wasted to a certain extent

[0006] To sum up, on the one hand, Diqing Tibetan pigs do not have full-price compound feeds that meet their nutritional needs, and the current feed is nutritionally unbalanced and cannot meet their nutritional needs, resulting in slow growth of Diqing Tibetan pigs , long feeding cycle, low breeding efficiency

On the other hand, the relatively precious local protein feed resource - walnut cake has not exerted its application value
