Pig feed trace element adding mode and use method thereof

Abstract

The invention relates to a novel pig feed trace element adding mode and a matched use method of the pig feed trace element adding mode, which mainly aim at five trace elements of Zn, Fe, Cu, Mn and Se in daily ration of weaned pigs of 10-20kg. According to the mode that Zn to Fe to Cu to Mn to Se is equal to 100:100:6.25:3.75:0.38 by weight, the adding amount of Zn, Fe, Cu, Mn and Se in the complete ration are determined. Under the trace element adding mode, the trace elements show a better combination effect, so that the adding amount of the trace elements can be reduced, the production performances are not influenced, the trace element adding cost can be reduced, the environmental pollution caused by the excessive discharge of the trace elements can be reduced, and better actual application effect is realized.

Description

technical field [0001] The invention relates to an addition mode and application method for five trace elements of zinc, iron, copper, manganese and selenium in feed rations for weaned piglets. Background technique [0002] Trace elements are one of the essential nutrients for animals. Although their content is small in animals, they play an important role in biochemical processes. Modern animal husbandry production puts too much emphasis on the role of trace elements, coupled with the low cost of trace elements, there is a large gap between the minimum required amount of animals and the maximum poisoning dose. In production practice, the content of trace elements in basic feed materials is usually not considered, but according to feeding standards In addition, the full amount or even excess of the demand in the production caused the widespread phenomenon of excessive supply and unbalanced supply of trace elements in production. Unreasonable addition of trace elements will ...

AI Technical Summary

Problems solved by technology

[0005] Excessive use of trace elements will not only cause a large amount of deposition in livestock and poultry tissues, but also produce toxic and side effects on the body, trace elements will also be excreted with feces, causing certain pollution to the environment

Especially in the current situation where the degree of intensification of pig production has been greatly improved, the stocking density and scale have increased sharply, and most feed companies or breeding companies are still using inorganic trace elements for commercial purposes. This will inevitably cause environmental pollution in the long run. severe damage to

[0006] 2. When trace elements are added to the feed, the background value of trace elements in raw materials and the addition ratio of trace elements are not considered

In the past, people paid more attention to the insufficient intake of trace elements, while ignoring the importance of the balance between trace elements. Deficiency or excess of elements can lead to adverse consequences

The imbalance between trace elements will have adverse effects on livestock and poultry production and the environment. If we can study the ideal trace element balance model like the ideal protein amino acid model, we can use the reasonable model of livestock and poultry trace elements to do To reduce the addition level of trace elements without affecting the production performance of livestock and poultry will have a huge impact on the addition and utilization of trace elements in livestock and poultry production
