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

Example Embodiment

[0025] Example 1

[0026] On the basis of preparing the basic diet, select Zn-MHA, Fe-MHA, Cu-MHA, Mn-MHA and selenium-enriched yeast trace element products, the net content of zinc, iron, copper and manganese are 10% respectively , the selenium content in selenium-enriched yeast is 0.1%. Prepare the diet as follows:

[0027] Step 1: Prepare the basal diet (that is, the diet without zinc, iron, copper and manganese, see Table 1). As shown in Table 1, the basal rations were formulated with reference to the nutritional needs of weaned piglets in NRC (1998).

[0028] The second step: determine the amount of zinc added in the above-mentioned prepared ration, that is, 80 mg of Zn is added to the full-price ration per kilogram.

[0029] Step 3: Then determine the amount of zinc, iron, copper, manganese and selenium to be added according to the pattern of Zn:Fe:Cu:Mn:Se=100:100:6.25:3.75:0.38.

[0030] Step 4: Convert the amount of zinc, iron, copper, manganese and selenium in t...

[0034] Example 2

[0035] Prepare the basal ration by the basal ration formula of Example 1, establish three groups and carry out comparative test, add inorganic trace elements (Zn, Fe, Cu, Mn are added according to its sulfate form, Se is added according to selenite) with NRC recommended amount. Sodium form added) (set as group 1), diets supplemented with Zn, Fe, Cu, Mn and Se in the mode of the present invention (set as group 2) and diets with commercially available premix (set as group 1) For group 3) do a comparative test. A total of 48 weaned piglets aged 24 days were selected, half male and half female. The pigs were healthy and similar in weaning age (24±1d). They were divided into 3 treatments, each treatment had 4 replicates, and each group had 4 pigs. There was no significant difference in the average initial body weight among the experimental treatment groups, which were fed the diets of Group 1, Group 2 and Group 3, respectively. The trial period was 28 days. ...

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 ...
