Embodiment 1

[0031] 1. Experimental animals, a total of 200 Congjiangxiang piglets were weaned in a local farm in Congjiang.

[0032] 2. Single factor experiment 1

[0033] Basic feed formula (w / w): corn 48%, broken rice 10%, bran 10%, bean cake 10%, fish meal 8%, green material 2.5%, calcium carbonate 0.5%, calcium phosphate 0.5%, salt 0.5%.

[0034] Feed additives:

[0035]

[0036]Take 40 piglets of Congjiangxiang piglets as experimental animals. The weaning date of this batch of piglets is the 12th to 14th day after birth and breastfeeding. This batch of piglets is divided into 4 groups with 10 piglets in each group. Fermented and dried powder group, grape seed fermented and dried powder group and hawthorn fermented and dried powder group. Among them, the basal feed group was fed with basal feed, the chrysanthemum chrysanthemum fermented and dried powder group was fed with different amounts (basic feed total weight 2-6%) of Chrysanthemum chrysanthemum fermented and dried powder co...

Embodiment 2

[0055] In another research project of the inventor, the inventor found that the fermented dried Chrysanthemum chrysanthemum powder can promote the growth of Xiangjiang pigs. Therefore, the inventor tried to add chrysanthemum chrysanthemum fermented dry powder with a weight of 4% of the total weight of the feed on the basis of the feed A in Example 1, and to feed according to the feeding method of Example 1. The results showed that, taking 20 weaned Congjiangxiang piglets as experimental animals, the average daily gain after feeding for 50 days could reach 189.26±0.03%, and the intramuscular fat content was 4.09±0.02%.

Embodiment 3

[0057] On the basis of embodiment 1, the present invention has adjusted the formula of feed A to be as follows:

[0058] Hawthorn fermented dry powder 20 parts, corn 45 parts, soybean meal 35 parts, bran 20 parts, alfalfa grass powder 5 parts, reed root powder 3 parts, fish meal 5 parts, compound amino acid 0.2 part, compound vitamin 0.04 part, fumaric acid sub 0.04 parts of iron, 3 parts of calcium carbonate, 0.01 parts of ferrous L-lactate, 0.5 parts of β-carotene, and 0.3 parts of table salt.

[0059] After adjusting the formula of the feed A, take 20 weaned Congjiangxiang piglets as experimental animals, and feed the weaned Congjiangxiang piglets according to the feeding method of Example 1. The feeding results found that within 50 days of age The average daily weight gain was 177.12±0.32g / d, and the intramuscular fat content was 4.06±0.03%.

Abstract

The invention provides a Guizhou local breeding method for pigs with high intramuscular fat content, which comprises the following steps: after suckling pigs are isolated from milk, feeding the suckling pigs with a feed A, wherein the feed comprises the following components: 20-60 parts of hawthorn fermented dry powder, 30-45 parts of corn, 20-35 parts of soybean meal, 20-30 parts of bran, 5-8 parts of alfalfa meal, 2-3 parts of reed rhizome powder, 3-5 parts of fish meal, 0.1-0.2 part of compound amino acid, 0.02-0.04 part of compound vitamin, 0.04-0.05 part of ferrous fumarate, 1-3 parts of calcium carbonate, 0.01-0.02 part of L-ferrous lactate, 0.5-1 part of beta-carotene, and 0.2-0.3 parts of table salt. According to the breeding method, the intramuscular fat content of the Congjiang Xiang pigs can be effectively increased to 4% or above, and the flavor of the Congjiang Xiang pigs can be improved; and the Congjiang Xiang pigs can obtain a good growth level.

Description

technical field [0001] The invention belongs to the technical field of livestock feeding, and in particular relates to a method for feeding Guizhou native pigs with high intramuscular fat content. Background technique [0002] Intramuscular fat is one of the key factors affecting meat quality, affecting tenderness, water retention, flavor and juiciness of meat (Ping Lu, Defa Li, Jingdong Yin, etc. Flavor differences of cooked longissimus muscle from Chinese indigenous pig breeds and hybrid pig breed (Duroc×Landrace×Large White)[J]. Food Chemistry, 2008.). Generally speaking, the intramuscular fat content can be increased by selecting additives, changing the energy level of the diet and enhancing the expression of certain genes. [0003] Congjiang Xiang pig is mainly produced in Qiandongnan Prefecture, Guizhou Province. It is famous for its "short size, tender meat, homozygous gene, and pure and pollution-free products". The intramuscular fat content of Congjiang Xiang pigs...
