Problems solved by technology

[0002] In recent years, with the rapid development of my country's pig industry, the degree of intensification has increased, domestic and foreign livestock and poultry trade has become increasingly frequent, and the chance of disease transmission has increased. Pig farmers generally use feed with additives such as antibiotics, hormones, and chemically synthesized drugs. Long-term use of these feeds will not only easily lead to problems such as drug resistance of pathogenic microorganisms, decline in animal immunity and product quality, but also increase harmful residues in poultry products and the environment, seriously threat to human health

Embodiment 1

[0026] Test one:

[0027] 1. Experimental Design

[0028] 2. Material Preparation

[0029] Experimental site: Pig farm of Guangxi Institute of Animal Husbandry.

[0030] Experimental species: Cinnamon pigs.

[0031] Experimental elephant grass / grass: purple elephant grass, Guimin grass, alfalfa, kudzu.

[0032] Remarks: The purple elephant grass variety in this example is a variety independently selected and bred by the applicant, which has been approved by the Guangxi Zhuang Autonomous Region (or the state).

[0033] This variety is introduced from Brazil, and its breeding method is as follows:

[0034] The Brazilian purple elephant grass is sexually propagated, and plants with high grass yield and good quality are selected for vegetative propagation by cuttings. In the expansion group, the single plant is selected for high yield, high crude protein content, many tillers, large leaf volume, and seed stems. Sturdy, pest-free seed stems, eliminating bad plants, after sever...

Embodiment 2

[0063] Test two:

[0064] A total of 420 30-day-old piglets with similar body weight were selected and randomly divided into 14 groups with 3 levels in each group and 10 piglets in each level. Each level is housed in a single-pen pigpen of the same size and environment, and is carried out according to the conventional feeding and management procedures of the pig farm. Free drinking water and feeding, routine management and breeding, the experimental period is 90 days.

[0065] Control group: conventional pig feed (that is, auxiliary material).

[0066] Treatment group A: 5% fermented purple elephant grass + 95% conventional pig feed (ie, adjuvant).

[0067] The specific treatment method of fermented purple elephant grass is as follows: the purple elephant grass is washed and then crushed, and then crushed to a length of 2-3cm, and then subjected to high pressure roller treatment by a high pressure roller, and then the treated forage is quickly placed. Put it into the ice ce...

Embodiment 3

[0107] Fermentation of purple elephant grass:

[0108] Experiment 1: The specific treatment method of fermented purple elephant grass is as follows: the purple elephant grass is washed and then crushed to a length of 2-3 cm, and then subjected to high pressure roller treatment through a high pressure roller turbine, and then the treated forage is Quickly put it into the ice cellar, add fructooligosaccharides and citric acid, stir, store in ice for 24 hours, take it out, immediately use 120 °C high fire while stirring for 3 minutes, then stop the fire, add EM bacteria and mix to build a heap for 3.5 days, and finally control The water content of purple elephant grass can be 6%.

[0109] Experiment 2: The specific treatment method of fermented purple elephant grass is as follows: the purple elephant grass is washed and then crushed to a length of 2-3 cm, and then subjected to high pressure roller treatment through a high pressure roller turbine, and then the processed forage, Q...

Abstract

The invention belongs to the technical field of biological feeds, and in particular relates to a feed for improving the diversity of pig intestinal microorganisms and an application thereof. The feed, in terms of weight percentage, comprises 15%-25% of fermented elephant grass and 75%-85% of auxiliary materials. %; the adjuvants are calculated by weight percentage, including corn flour 30%, soybean meal 25%-35%, bran 15%, mineral premix 3%, and vitamin premix 2%. The applicant has found through research that this natural and nutritious feed can improve the microbial diversity in pig intestines, improve feed digestibility, promote pig growth and development, and reduce the incidence of pig intestines.

Description

【Technical field】 [0001] The invention belongs to the technical field of biological feed, and in particular relates to a feed for improving the diversity of pig intestinal microorganisms and its application. 【Background technique】 [0002] In recent years, with the rapid development of my country's pig industry, the increase in the degree of intensification, the increasing frequency of domestic and foreign livestock and poultry trade, and the increasing opportunities for disease transmission, pig farmers generally use feeds with additives such as antibiotics, hormones, and chemical synthetic drugs. To prevent and control and ensure the health of livestock and livestock, the long-term use of these feeds is not only easy to cause problems such as drug resistance of pathogenic microorganisms, decline in animal immunity and product quality, but also cause harmful residues in livestock products and the environment. threaten human health. The pig intestines are populated by complex...
