Problems solved by technology

Chronic oxidative stress will reduce the immune ability of piglets, mainly manifested in the increased susceptibility of piglets to diseases, the decline of piglet production performance, resulting in the extension of the growth cycle from piglets to fattening pigs, and the delay of slaughtering time, which seriously affects the benefits of pig production

Embodiment 1

[0032] The feeding method for alleviating chronic oxidative stress of piglets of the present embodiment comprises the following steps:

[0033] 1) Prepare piglet feed containing acidic amino acids.

[0034] First, weigh soybean meal, fish meal, wheat bran, whey powder, glucose, soybean oil, lysine, methionine, threonine, tryptophan, calcium hydrogen phosphate, stone powder, salt, trace element premix and corn, It is then mixed well to make a basal diet. The mass fractions of each raw material component in the basal diet are: soybean meal 15.0wt%, fish meal 6.0wt%, wheat bran 0.5wt%, whey powder 1.8wt%, glucose 2.6wt%, soybean oil 3.6wt%, Lysine 0.2wt%, methionine 0.4wt%, threonine 0.65wt%, tryptophan 0.05wt%, calcium hydrogen phosphate 0.6wt%, stone powder 0.4wt%, salt 0.2wt%, trace element premix 1.5wt %, corn 66.5wt%.

[0035]The proportioning of the trace element premix in the above-mentioned basal diet is: sepiolite 74.74wt%, general compound multidimensional 3.0wt%, co...

Embodiment 2

[0040] The feeding method for alleviating chronic oxidative stress of piglets of the present embodiment comprises the following steps:

[0041] 1) Prepare piglet feed containing acidic amino acids. First, prepare the basal diet according to the same method as in Example 1. The difference from Example 1 is that the mass fractions of each raw material component in the basal ration are: soybean meal 16.5wt%, fish meal 5.0wt%, wheat bran 0.2wt%, whey powder 2.3wt%, glucose 4.6wt% %, soybean oil 2.5wt%, lysine 0.5wt%, methionine 0.3wt%, threonine 0.35wt%, tryptophan 0.15wt%, calcium hydrogen phosphate 1.5wt%, stone powder 0.8wt%, salt 0.4wt% , trace element premix 0.8wt%, corn 64.1wt%. Secondly, the acidic amino acid is weighed according to the preset ratio, then added into the basal ration, mixed evenly, and the feed for piglets is prepared. The acidic amino acid is preferably aspartic acid, more preferably the proportion of aspartic acid in piglet feed is 0.30wt%.

Embodiment 3

[0044] The feeding method for alleviating chronic oxidative stress of piglets of the present embodiment comprises the following steps:

[0045] 1) Prepare piglet feed containing acidic amino acids. First, prepare the basal diet according to the same method as in Example 1. The difference from Example 1 is that the mass fractions of each raw material component in the basal ration are: soybean meal 17.8wt%, fish meal 6.0wt%, wheat bran 0.3wt%, whey powder 2.6wt%, glucose 3.0wt% %, soybean oil 3.0wt%, lysine 0.8wt%, methionine 0.5wt%, threonine 0.4wt%, tryptophan 0.10wt%, calcium hydrogen phosphate 1.2wt%, stone powder 0.5wt%, salt 0.3wt% , trace element premix 1.0wt%, corn 62.5wt%. Secondly, the acidic amino acid is weighed according to the preset ratio, then added into the basal ration, mixed evenly, and the feed for piglets is prepared. The acidic amino acid is preferably aspartic acid, more preferably the proportion of aspartic acid in piglet feed is 0.50wt%.

Abstract

The invention discloses a feeding method and feed for relieving chronic oxidative stress of piglets. The feeding method comprises the step of feeding piglets with feed containing acidic amino acid, wherein the acidic amino acid is aspartic acid. The feed disclosed by the invention is feed containing 0.15 to 0.80 weight percent of aspartic acid. By adopting the feeding method and the feed to breed the piglets, the immunity of the piglets can be improved, the harm of oxidative stress to the piglets can be relieved, and the healthy growth of the piglets can be promoted.

Description

technical field [0001] The invention belongs to the technical field of animal breeding, and in particular relates to a feeding method and feed for alleviating chronic oxidative stress of piglets. Background technique [0002] Excessive oxygen free radicals destroy the dynamic balance between the body's oxidation and antioxidant defense systems, causing the body to produce oxidative stress. Some problems in the process of livestock and poultry breeding, such as group transfer, transportation, odor, temperature and noise, etc. can cause oxidative stress in the body; at the same time, compared with acute oxidative stress, the stimulation intensity of chronic oxidative stress is relatively weakened, and the stimulation time Prolonged and increased in frequency, therefore, chronic oxidative stress is more common and frequent. Chronic oxidative stress can reduce the immune ability of piglets, which is mainly manifested in the increased susceptibility of piglets to diseases and th...
