Problems solved by technology

[0002] The long-term temperature in southern my country is high in summer, and laying hens are prone to heat stress. Heat stress causes laying hens to reduce feed intake, reduce egg production and quality, and increase mortality, which brings great losses to livestock production.
[0003] Common anti-heat stress nutritional measures are adding vitamin C or anti-stress drugs to drinking water. Although it has certain effects, the operation is cumbersome and cannot solve a series of nutritional problems such as increased energy requirements and changes in trace element requirements during heat stress. question

Embodiment 1

[0034] An anti-heat stress premix for laying hen feed of the present invention comprises the following components by mass ratio: 5% amino acid, 15% vitamin premix, 20% trace element mixture, 23% calcium hydrogen phosphate, Emulsified oil powder 30%, salt 3%, cat's whiskers extract 4%;

[0035] Wherein, among the amino acids, the content of each component is as follows: methionine 75.0% (accounting for 3.75% of the total heat stress premix), lysine 4.5%, threonine 1.5%, tryptophan 19.0%;

[0036] Among them, in the vitamin premix, the content of each component is as follows: vitamin A 5.000‰ (accounting for 0.750‰ of the total heat stress resistance premix), vitamin B1 0.450‰, vitamin B2 0.900‰, vitamin B3 7.000‰, vitamin B51.750‰, Vitamin B9 0.175‰, Vitamin B12 0.003‰, Vitamin C 50.000‰, Vitamin D3 6.500‰, Vitamin E 20.000‰, Vitamin H 0.020‰, Vitamin K 0.100‰, Choline Chloride 130.000‰, Defatted Rice Bran 778.102 ‰;

[0037] Wherein in the trace element mixture, the content ...

Embodiment 2

[0056] Adopt 120 30-week-old Hailan gray laying hens to carry out the experiment, carry out in the same chicken coop (consistent temperature) with embodiment 1, feed and test scheme are exactly the same as embodiment 1.

[0057] For test results, see Figure 8-13 , Figure 8-9 For the influence of the premix of the present invention on the body weight, average egg weight, feed-to-egg ratio, and egg production rate of Hailan gray laying hens during the heat stress period, * has a significant difference compared with group C (p Figure 10-13 For the effect of the premix of the present invention on Hy-Line gray eggs during the heat stress period, the protein height, Haugh unit, eggshell strength, and egg yolk color, * are significantly different from group C (p<0.05).

[0058] Depend on Figure 8-9 It can be seen that the feed premix of the present invention has no effect on the average egg weight and body weight of Hailan gray laying hens during the peak egg production period, a...

Embodiment 3

[0062] The anti-heat stress premix of the present embodiment comprises the following components by mass ratio: 5% of amino acid, 15% of vitamin, 20% of trace element, 25% of carrier (calcium hydrogen phosphate), 28% of emulsified oil powder, 3.5% of salt %, cat's whiskers extract 3.5%;

[0063] Wherein the composition of amino acids is as follows: 73.5% methionine (accounting for 3.675% of the total amount of anti-heat stress premix), 5.5% lysine, 1.0% threonine, 20.0% tryptophan;

[0064] The composition of the vitamin premix is ​​as follows: vitamin A 5.000‰ (accounting for 0.750‰ of the total heat stress premix), vitamin B1 0.450‰, vitamin B2 0.900‰, vitamin B3 7.000‰, vitamin B5 1.750‰, vitamin B9 0.175‰, vitamin B12 0.003‰, vitamin C 45.000‰, vitamin D3 6.500‰, vitamin E25.000‰, vitamin H 0.020‰, vitamin K 0.100‰, choline chloride 130.000‰, vitamin carrier calcium hydrogen phosphate 778.102‰;

[0065] Wherein the composition of the trace element mixture is as follows: ma...

Abstract

The invention discloses a heat-stress-resistant premix used for laying hen feed. The heat-stress-resistant premix is prepared from the following components in percentage by weight: 5-8% of amino acid,10-15% of a vitamin mixture, 16-20% of a trace element mixture, 20-25% of a carrier, 30-35% of emulsified oil powder, 0.30-0.60% of salt and 0.10-0.80% of a spicate clerodendranthus herb extract, wherein trace elements in the trace element mixture comprise manganese, copper, zinc, iron, copper, zinc, iodine, selenium and chromium. The spicate clerodendranthus herb extract is adopted as a poultryadditive, the good antioxidant capability and intestinal epithelium protection effect are achieved, the egg yield of laying hens during heat stress is increased, and the egg quality is improved; the physiological index of the laying hens during heat stress is improved, and the laying hens are promoted to keep healthy; and the working procedure during heat stress is simplified, economic benefits are increased, and using is easy, convenient, safe and effective.
