Low-cost efficient pig feed and preparation method thereof

Abstract

The invention provides a low-cost efficient pig feed. Each 100 parts by weight of feed is prepared from the following raw materials in parts by weight: 30-40 parts of straw waste, 10-20 parts of distiller's grains, 5-10 parts of bicarbonate soda, 5-25 parts of bean dregs, 0.1-0.3 part of lysine, 0.01-0.1 part of methionine, 0.05-0.12 part of threonine, and 1-3 parts of a compound microorganism preparation, wherein the strain combination of the compound microorganism preparation is selected from at least two of coriolus versicolor, aspergillus oryzae, saccharomyces cerevisiae, neurospora sitophila and bacillus subtilis. The matched feed formula provided by the invention is balanced and rich in nutrition, the interaction between multiple probiotics and the raw materials is reasonably used toobtain a good fermenting effect, the sufficient development of waste resources such as straw, bean dregs and distiller's grains is realized, the requirement of sustainable development is met, the feeding cost is reduced, the production benefits are improved, and the environmental pollution can be reduced.

Description

technical field [0001] The invention belongs to the field of livestock breeding feed, and in particular relates to a low-cost and high-efficiency pig feed and a preparation method thereof. Background technique [0002] Straw is the product of photosynthesis of crops, which stores rich nutrients and is a valuable source of roughage. my country is a large agricultural country with abundant crop straw resources. At present, there are nearly 20 kinds of crop straws with a wide planting area, and the output is huge. In this kind of crop straw, the dry matter content that can provide energy to animals accounts for about 65% to 80%, but the utilization rate of straw is less than 10%. The main reason is that most of the crop straw is still used as fuel or directly returned to the field. Waste of resources and pollute the environment. The production and application of straw micro-storage feed can make up for and replace part of the concentrate. While reducing the cost of feed, it h...

Problems solved by technology

In this kind of crop straw, the dry matter content that can provide energy to animals accounts for about 65% to 80%, but the utilization rate of straw is less than 10%. The main reason is that most of the crop straw is still used as fuel or directly returned to the field. Waste of resources and pollute the environment

However, due to factors such as high water content, easy corruption, inconvenient transportation, and unbalanced nutritional composition, it is difficult for fresh distiller's grains to be digested and absorbed by livestock and poultry, and the utilization rate of nutrients is low.
