Embodiment 1

[0021] First, the eucalyptus leaf extract and zeolite powder were pulverized, and 280 g of eucalyptus leaf extract, 190 g of zeolite powder, 160 g of potassium sulfate, 150 g of sodium bicarbonate, 130 g of magnesium sulfate, and 90 g of lysine were weighed respectively. Potassium sulfate, magnesium sulfate, and lysine are dissolved in 3.8L of water to form a trace element solution, and then the pulverized eucalyptus leaf extract and zeolite powder are poured into the above solution and fully stirred. The mixture was homogenized three times under the condition of a high-pressure homogenizer of 5Mpa to fully mix the sample, and the dry mixture sample was obtained under the conditions of spray drying at an air inlet temperature of 180°C and an air outlet temperature of 90°C. Finally, sodium bicarbonate was added to the dry mixture sample, and after thorough mixing, 1 kg of anti-chicken heat stress premix was obtained. Eucalyptus leaf extract is a hydroalcoholic extract obtained ...

Embodiment 2

[0023] First, the eucalyptus leaf extract and zeolite powder were pulverized, and 260 g of eucalyptus leaf extract, 210 g of zeolite powder, 160 g of potassium sulfate, 140 g of sodium bicarbonate, 150 g of magnesium sulfate, and 80 g of lysine were weighed respectively. Potassium sulfate, magnesium sulfate, and lysine are dissolved in 3.9L of water to form a trace element solution, and then the pulverized eucalyptus leaf extract and zeolite powder are poured into the above solution and fully stirred. The mixture was homogenized three times under the condition of a high-pressure homogenizer of 5Mpa to fully mix the sample, and the dry mixture sample was obtained under the conditions of spray drying at an air inlet temperature of 180°C and an air outlet temperature of 90°C. Finally, sodium bicarbonate was added to the dry mixture sample, and after thorough mixing, 1 kg of anti-chicken heat stress premix was obtained.

Embodiment 3

[0025] A total of 200 chickens with similar body weight and normal growth were selected and randomly divided into 4 treatment groups with 5 repetitions in each group. Group A is the control group, fed with normal basal feed; Group B, added 0.6g / kg anti-heat stress chicken premix to the basal feed; Group C, added 0.9g / kg anti-heat stress chicken premix to the basal diet Chicken premix; group D, add 1.2g / kg anti-heat stress chicken premix to the basal diet. During the feeding process, the animals were fed ad libitum, and the same feeding management was adopted. The experimental environment was 35°C±1°C, and the test period was 40 days. The index of investigation is mainly anti-oxidation index.

[0026]

[0027] The anti-heat stress chicken premix consists of 28% eucalyptus leaf extract, 19% zeolite powder, 16% potassium sulfate, 15% sodium bicarbonate, 13% magnesium sulfate, and 9% lysine.

[0028] The results showed (Table 1): the anti-heat stress chicken premix had no sig...

Abstract

The invention discloses an anti-chicken heat stress premix and a preparation method thereof, and the anti-chicken heat stress premix comprises the following components by weight: 25%-30% of eucalyptusleaf extract, 15%-20% of zeolite powder, 14%-19% of potassium sulfate, 12% to 17% of sodium bicarbonate, 10% to 15% of magnesium sulfate, and 7% to 12% of lysine. The anti-chicken heat stress premixcan effectively prevent and resist h heat stress response of broiler and laying hens in a hot environment, improves the environmental adaptability of the broiler and laying hens, and reduces the mortality of the broiler and laying hens, and the product quality is stable during the preparation process, a chicken feed is prepared according to the addition proportion of the premix of 0.3%-0 .6%, in the high temperature environment above 32 DEG C, the anti-chicken heat stress capability can be effectively improved, the chicken's ability to resist temperature rising, respiratory rate acceleration and other heat stress response can be improved, and the incidence of heat stress can be greatly reduced.

Description

technical field [0001] The invention relates to a feed additive premix, in particular to a feed premix for broilers and laying hens and a preparation method thereof. Background technique [0002] Heat stress is a ubiquitous problem in poultry production and causes huge losses every year (ambient temperature >32°C). Because broilers have no sweat glands and have poor heat dissipation ability, when the ambient temperature rises beyond its own adjustment ability, it will cause heat stress response, cause metabolic disorders of the nervous system and endocrine system of the body, lead to a series of problems such as low production performance and significant decline in meat quality . The extreme high temperature weather in Guangdong and other places in my country has seriously affected the poultry industry. Along with the decline in the quality of poultry products, it also affects the daily life of ordinary consumers. Chicken heat stress has greatly limited the development ...
