Abstract

The invention discloses a feed capable of relieving heat stress of laying hens, which comprises the following raw materials: corn, soybean meal, bran, a Chinese herbal medicine compound, fish meal, stone powder, calcium hydrophosphate, methionine, cystine, lysine, compound vitamins and compound probiotics, the mass ratio of the corn to the soybean meal to the bran to the Chinese herbal medicine compound to the fish meal to the mountain flour to the calcium hydrophosphate to the methionine to the cystine to the lysine to the compound vitamins to the compound probiotics is (50-100): (10-20): (1-5): (1-5): (2-8): (1-4): (1-2): (0.1-0.15): (0.1-0.2): (0.01-0.01): (0.1-1): (0.1-1). The invention further discloses a preparation method of the feed capable of relieving heat stress of laying hens.

Description

Technical field [0001] The present invention relates to the field of layer heat stress technology, in particular to a feed capable of relieving layer heat stress and a preparation method thereof. Background [0002] Due to the high summer temperature in southern China, the breeding process of layer chickens is easy to enter the state of heat stress, once the layer chicken heat stress occurs, it will cause shortness of breath, which will lead to a decrease in the concentration of hydrogen ions and carbon dioxide in the blood, resulting in acid-base imbalance, that is, respiratory alkali poisoning, the pH value of the blood of the layer chicken body will increase, thereby reducing the reserve of alkali, resulting in a reduction in potassium ions, chloride ions and sodium ions in the plasma of layer chickens in a high temperature environment. From the research point of view, when the layer chicken is exposed to the environment at 35 ° C for one hour, respiratory alkalosis will occur...
