Problems solved by technology

[0003] In the whole process of raising pigs, the cost of feed accounts for the largest proportion, and the cost of feed for growing and finishing pigs accounts for nearly 70% of the total feed cost of the pig farm. The growth rate of pigs is fast, and the development of the body and internal organs is uncoordinated, so its nutritional requirements are high
If the nutrition is not enough at this time, it is prone to problems such as low immunity

Embodiment 1

[0036] The embodiment of the present invention provides a low-protein feed for growing and finishing pigs. Specifically, the low-protein feed for growing and finishing pigs is composed of a low-protein small peptide amino acid balanced ration composed of conventional feed materials, small peptide products and amino acids, wherein , the weight ratio of the small peptide product in the feed is less than or equal to 3%.

[0037] A low-protein diet refers to a pig diet in which the crude protein level of the diet is 1-4 percentage points (for example, 3 percentage points) lower than the normal diet. The theoretical basis for the application of a low-protein diet is the amino acid balance theory of ideal protein, that is Lysine is 100, and the ratio of other amino acids to lysine reaches the best balance. By adding amino acids to low-protein diets and reducing the amount of protein feed such as soybean meal, the content of essential amino acids can reach normal diets (that is, high-...

Embodiment 2

[0041] The following embodiments of the present invention describe specific examples of growing and finishing pigs, so that those skilled in the art can clearly understand the technical solutions and technical effects of the present application.

[0042] 1. Materials and methods

[0043]1. Test time: September 30, 2016 to November 23, 2016

[0044] 2. Test location: Zhangjiakou Hongji Animal Husbandry Development Co., Ltd.

[0045] 3. Test method: Select 300 healthy and disease-free Du Chang Sanyuan commercial pigs with similar weight and age. They were randomly divided into 5 treatments, from treatment 1 to treatment 5, with 60 pigs in each treatment, and the ratio of male to female was 1:1. Further, each treatment was divided into 4 replicates, that is, 15 pigs per replicate. Treatment 1 was fed normal feed, treatment 2 was fed low protein (Low Protein, referred to as LP) diet + amino acid (Amino Acid, referred to as AA), treatment 3 was fed LP+1%T30+AA diet, treatment 4 ...

Abstract

The invention discloses a low-protein feed for growing-finishing pigs, belonging to the technical field of breeding of growing-finishing pigs. The level of crude proteins in the feed is reduced by 3%on the premise of guaranteeing breeding effect; and through addition of small peptides and amino acids, a low protein / small peptide / amino acid balanced diet is formed, so feed cost is reduced and pigbreeding cost is lowered. The low-protein feed for growing-finishing pigs is the low protein / small peptide / amino acid balanced diet composed of conventional feed raw materials, small peptides and amino acids, and the weight ratio of small peptide products in the low-protein feed is less than or equal to 3%. The low-protein feed is applied to breeding of growing-finishing pigs.

Description

technical field [0001] The invention relates to the technical field of fattening pig feeding, in particular to a low-protein feed for growing and fattening pigs. Background technique [0002] Fattening pigs refer to 60-120kg pigs, that is, pigs that are being fattened. For a pig farm, fattening pigs are the last link in pig production, the stage with the best management, the stage where pigs have the lowest requirements on environmental conditions, and the final sprint stage for pig farms to make money. Performance determines how profitable a pig farm is. Therefore, it is of great importance to the whole pig production, and it is also related to economic benefits. [0003] In the whole process of raising pigs, the cost of feed accounts for the largest proportion, and the cost of feed for growing and finishing pigs accounts for nearly 70% of the total feed cost of the pig farm. The growth rate of pigs is fast, and the development of the body and various internal organs is ...
