Method for processing livestock and poultry feed from waste and inferior tobacco leaves

Abstract

A method for processing livestock and poultry feed from waste and inferior tobacco leaves comprises steps as follows: 1, treatment of the waste and inferior tobacco leaves; 2, anaerobic fermentation treatment; 3, quality evaluation and utilization: unsealing a container for quality evaluation after 45 days of sealed anaerobic fermentation, and taking tobacco leaves ranked top and medium classes in the quality evaluation with a sensory evaluation method as feed to replace part of green feed to feed cow and sheep or mixing the tobacco leaves with concentrated feed to feed pigs and poultry. The waste and inferior tobacco leaves which are not suitable to be used as flue-cured tobacco are turned into the available feed resource with the technology, so that pollution and flue-cured tobacco planting disease propagation due to the fact that the waste and inferior tobacco leaves are abandoned on edges of fields are avoided, and the problem of non-point source pollution caused by flue-cured tobacco planting organic waste is effectively solved. The method has the advantages that the facility and equipment investment is low, the feed preparation process is convenient, the method can be by flue-cured tobacco planters easily, and the popularization and application range is wide. Once the method is applied by the flue-cured tobacco planters, the contradiction of insufficient high-quality forage resources of the breeding industry can be effectively relieved, and the method plays roles in decreasing the breeding cost and increasing the breeding benefit.

Description

technical field [0001] The invention relates to the field of recycling waste tobacco leaves, in particular to a method for processing livestock and poultry feed by using waste tobacco leaves. Background technique [0002] my country is a large flue-cured tobacco production country. After the 1990s, my country's annual tobacco output is more than 2 million tons, of which Yunnan Province has the largest tobacco output. After the implementation of "dual control" of flue-cured tobacco, the area of ​​flue-cured tobacco in Yunnan has also stabilized at 333,000 hm 2 Around, the output accounts for about 30% of the total national output. However, before fresh tobacco leaves are harvested, it is necessary to remove 2 tobacco leaves at the bottom of the plant and 1 tobacco leaf at the top. These 3 leaves are usually called waste tobacco leaves, 1hm 2 Flue-cured tobacco has about 1.5 tons of fresh and waste tobacco leaves. Most of them are discarded in the fields to cause environment...

AI Technical Summary

Problems solved by technology

However, due to the large amount of nicotine contained in the waste tobacco leaves (Gao Yuncai et al. reported that the upper leaves are 3.22% to 3.46%, and the lower leaves are 1.63% to 2.27%), on the one hand, the palatability is seriously affected, and on the other hand, the animals have long-term intake of tobacco. Alkali may be transferred to livestock and poultry products, resulting in a decline in the quality of livestock and poultry products
