Embodiment 1

[0121] Embodiment 1, the impact of low-protein amino acid balance diet on piglet production performance

[0122] Selection of experimental pigs and experimental diet design:

[0123] 90 commercial hybrid piglets of the same age and body weight of about 15kg were selected as experimental animals, and were completely randomly divided into 3 groups, each group was set up with 3 replicates, and each replicate had 10 pigs. A total of 3 protein levels were designed for the experimental diet, namely control, experiment 1 and experiment 2. The composition and nutritional level of the experimental diet are shown in Table 1. The control group was the basal ration. In Experiment 1 and Experiment 2, the amount of soybean meal was reduced by 6% and 8% respectively on the basis of the control group, and the amount of corn was increased correspondingly to balance the ration. The diet was powder feed, and the test period was 30 days.

Embodiment 2

[0191] Embodiment 2, the impact of low-protein amino acid balanced diet on the production performance of weaned piglets

[0192] Selection of experimental pigs and experimental diet design:

[0193] 90 commercial hybrid piglets of the same age and body weight of about 15kg were selected as experimental animals, and were completely randomly divided into 3 groups, each group was set up with 3 replicates, and each replicate had 10 pigs. A total of 3 protein levels were designed for the experimental diet, namely control, experiment 1 and experiment 2. The composition and nutritional level of the experimental diet are shown in Table 5. The control group was the basal diet. In Experiment 1 and Experiment 2, the amount of soybean meal was reduced by 6% and 8% respectively on the basis of the control group, and the amount of corn was increased correspondingly to balance the diet. The diet was powder feed, and the test period was 30 days.

Embodiment 3

[0260] Embodiment 3, the effect of low-protein diet on the performance of growing pigs and the concentration of NH3 and H2S in piggery

[0261] Selection and grouping of experimental animals:

[0262] In the experiment, 72 three-way hybrid pigs with no significant difference in body weight were selected and randomly divided into three groups (ie, control group A, test group B, and test group C). Groups A, B, and C were randomly assigned to three small environmental houses in the same building separated by spacers, with no gas convection, relatively independent, and consistent environment. Repeat for 8 pigs. The pre-test period is 7 days, and the formal test period is 40 days.

[0263] Formula design of low-protein amino acid balanced diet:

[0264]In this experiment, the 17% crude protein diet was used as the control group A, and the 15% and 14% low-protein diets were used as the test groups B and C respectively. In the diet of the experimental group, 0.4wt% of compound ad...

Abstract

The invention discloses a low-protein amino acid balance daily ration, a preparation method and the application thereof. The daily ration comprises the components based on parts by weight: 68-80 partsof corn, 3-20 parts of bean pulp, 6-20 parts of wheat bran and 4-5 parts of pre-mixed material, wherein the pre-mixed material comprises the following components: pig multi-vitamin, pig compound trace element, lysine, methionine, threonine, tryptophan, choline chloride, calcium carbonate, calcium hydrogen phosphate, phytase, common salt, ethoxy quinoline, trimethylamine B lactone, sodium glutamate and zeolite powder. Based on summary of the existing experimental data, the low-protein daily ration combines the actual conditions of China, utilizes the latest data information of raw materials made in China, fully takes the organic combination of the pre-mixed material and the main raw materials into account, and adopts a net energy system structure and a new nutrition model, thus developingthe utilization rate of feed to the utmost extent on the premise of ensuring the quality of animal products.

Description

technical field [0001] The invention relates to a low-protein amino acid balanced ration and its preparation method and application. Background technique [0002] Low-protein diet refers to a diet that reduces the protein level in the diet by 2% to 4%, and at the same time meets the needs of the type, proportion and quantity of amino acids in the diet of livestock and poultry, but the production performance of livestock and poultry remains unchanged. Since the essence of animal protein nutrition is amino acid nutrition, and more importantly, essential amino acids, so while reducing the crude protein content of the diet, supplementing essential amino acids can solve the problem of lack of some essential amino acids caused by low crude protein content. . As more and more industrial amino acids (L-lysine, L-threonine, L-methionine and L-tryptophan) come on the market and gradually decrease in price, the use of low-protein diets in production has become a A real possibility. ...
