Problems solved by technology

[0004] The above adjustments to relieve weaning stress are mainly focused on regulating the gastrointestinal flora and improving the immune function of the body, but less consideration is given to the immature digestive tract of early weaned piglets, that is, the internal cause of intestinal damage

Embodiment 1

[0029] A kind of pig feed that promotes intestinal tract development of piglets, its formula is as follows:

[0030]

[0031] Described acidulant is the benzoic acid that DSM China Co., Ltd. produces, 99.5% purity.

[0032] The antioxidant is Danquiline No. 2 produced by Jiangsu Zhongdan Group Co., Ltd., and the main component is ethoxyquinoline.

[0033] The components of the premix are (by weight): retinol, 0.0076; vitamin D3, 0.0006; vitamin E, 0.16; vitamin K3, 0.03; vitamin B 12 , 0.0002; riboflavin, 0.04; niacin, 0.3; pantothenic acid, 0.12; choline chloride, 6; folic acid, 0.003; vitamin B1, 0.015; vitamin B6, 0.03; biotin, 0.001; 4 ·7H 2 O, 3.6; MnSO 4 ·5H 2 O, 0.9586; FeSO 4 ·H 2 O, 2.52; CuSO 4 ·5H 2 O, 1; KI, 0.006; Na 2 SeO 3 ·5H 2 O, 0.008; Carrier (the medical stone of 70% mass ratio and the defatted rice bran of 30% mass ratio), 85.2

Embodiment 2

[0040] An application of a pig feed for promoting intestinal development of piglets in the preparation of preparations for repairing intestinal tracts of piglets, the application process is as follows:

[0041] Select 16 piglets from 4 litters, pair them into 2 groups according to the principle of similar litter and body weight, start supplementing the feed described in Example 1 from the age of 3 days of piglets, and the control group eats certain commercially available piglets with the same price. All were fed ad libitum. The piglets were weaned at the age of 14 days, slaughtered and sampled on the 3rd day after weaning, and the growth performance and intestinal structure and function of the test pigs were detected.

[0042] piglet growth performance see figure 1, the birth weights of the test group and the control group were 1.32±0.21kg and 1.32±0.24kg respectively, and when eating different feeds until 17 days old, the body weights were 4.81kg and 5.37kg respectively, and...

Embodiment 3

[0050] An application of a pig feed for promoting intestinal development of piglets in the preparation of preparations for repairing intestinal tracts of piglets, the application process is as follows:

[0051] 160 piglets were selected from 20 litters and divided into two groups according to the principle of same litter and similar body weight.

[0052] The piglets in the control group began to freely eat a commercially available creep feed for piglets at the same price from the age of 3 days, and continued until the age of 21 days;

[0053] The piglets in the test group began to supplement the feed described in Example 1 from the age of 3 days, and had free access to food until 7 days after weaning at the age of 14 days (21 days of age).

[0054] At the age of 21 days, the growth performance was detected, and 8 pigs were slaughtered and sampled in the control group and the experimental group respectively, and the intestinal structure and function were detected.

[0055] pig...

Abstract

The invention discloses a pig feed for promoting intestinal development of piglets and application of the pig feed. According to the pig feed, a reasonable and scientific formula is adopted, digestive physiological characteristics and nutritional requirement of intestinal development of the piglets are considered fully, ingredients of whey powder, cane sugar, glucose, soybean oil and the like are added, the relevant property and the digestibility are improved, sufficient energy substances are provided for intestinal growth, inadequate energy supply of intestine during stress is relieved, internal cause of intestinal injury is considered, promotion of advanced intestinal maturation is considered, functional amino acids are utilized to promote intestinal growth, and proline provides a precursor of polyamine synthesis in a piglet intestine and can promote intestinal maturation to advance weaning day-old of the piglets.

Description

technical field [0001] The invention relates to the application field of feed additives, in particular to a pig feed for promoting intestinal tract development of piglets and its application. Background technique [0002] Intestinal growth is the core of piglet growth and development and the basis for rapid growth. The intestine is the place where the body digests and absorbs nutrients, and it also has an important defense function. Poor appetite, digestive disorders, diarrhea, and slow growth of piglets caused by weaning have always been a problem that plagues the pig industry. Due to the insufficient intestinal development of piglets, early weaning can easily lead to great changes in the morphology, structure and function of the small intestinal mucosa of piglets, inhibiting the full development of growth potential, which is the biggest technical obstacle to implementing early weaning. [0003] Nutrition is the most effective way to regulate the repair of intestinal dama...
