Problems solved by technology

However, studies have shown that there is an antagonistic or synergistic relationship between different trace elements in the feed. Too high or too low a certain element content will lead to a decrease in the utilization rate of other elements and an increase in emissions.
In addition, trace elements contained in feed that exceed the actual needs of broilers will also be excreted into the environment with feces, causing serious environmental pollution

Embodiment

[0026] The method for determining the content of trace elements in broiler feed in this embodiment includes determining the content of trace elements in the feed according to the relationship between the excretion of trace elements and the content of trace elements in the feed, combined with the requirement to minimize the excretion of trace elements in the breeding process ; Wherein the relationship between the excretion of trace elements and the content of trace elements in the feed is:

Abstract

The invention relates to the technical field of feed processing and in particular relates to feed for 4-week-age to 6-week age broiler chickens and a determination method of the content of microelements in the feed. The method comprises: aiming at the requirement of reducing an excretion amount of the microelements in a culture process, determining a suitable level of the microelements in the feed according to a relation between the excretion amount of the microelements and the content of the microelements in the feed, so as to provide theoretical guidance for reasonable addition of the microelements in the feed. According to the feed provided by the invention, the optimal use amount of copper, iron, zinc and manganese in the feed can be determined according to the requirement of reducing the content of the microelements in the excrement in an actual culture process; a balance mode of the microelements including the copper, the iron, the zinc and the manganese in the broiler chickens can be developed and the pollution to the environment, caused by the microelements, is reduced.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a feed for broilers aged 4 to 6 weeks and a method for determining the content of trace elements in the feed. Background technique [0002] Trace elements have important nutritional and physiological functions and are indispensable nutrients for animals to maintain life activities. Previous studies on animal trace elements mainly aimed at the prevention and treatment of trace element deficiency and the excavation of the special biological functions of trace elements. Add Effect". However, studies have shown that there is an antagonistic or synergistic relationship between different trace elements in the feed. Too high or too low a certain element content will lead to a decrease in the utilization rate of other elements and an increase in emissions. In addition, trace elements contained in feed that exceed the actual needs of broilers will also be excreted into the envir...
