Problems solved by technology

At the same time, it is worth noting that the development of the breeding industry has also caused serious pollution to the environment. According to estimates, each pig in the pig industry produces an average of 2.5 tons of feces and urine per year, and a farm of 10,000 pigs discharges feces to the surrounding environment at least every year. 30,000 tons, the daily sewage volume is 100-150 tons, and there are more than 200 kinds of fecal odor components; and because there is currently no nutritional feed for Licha black pigs, the protein, amino acids and Phosphorus metabolism is low, so pollution is more serious

Embodiment 1

[0057] In order to verify the feeding effect of the full-price compound feed of the present invention on Licha black pigs, the technical department of the applicant company conducted a feeding test in the experimental base of the College of Animal Science and Technology of Shandong Agricultural University in April 2015. A single factor comparative experimental design was adopted. 24 healthy castrated Licha black weaned piglets with similar parity and body weight were selected and randomly divided into experimental group 1, experimental group 2, experimental group 3, and experimental group 4, each group including 6 replicates. The feeding method is ad libitum. The feeding stage is Licha black pig 10-90kg.

[0058] In the experimental group, the feed formula for piglets in the 10-35kg stage: 590 parts of corn, 100 parts of secondary powder, 175 parts of soybean meal, 80 parts of corn DDGS, 13 parts of soybean oil, 3.6 parts of lysine, 0.4 parts of methionine, 0.3 parts of threon...

Embodiment 2

[0103] In order to verify the improvement effect of the feed of the present invention on the growth performance of Licha black pigs, the technical department of the applicant company conducted a feeding test on 80 black pigs in the original breeding farm of Licha black pigs in December 2015. The growth cycle of Licha black pigs is divided into three stages: 10-35kg, 35-65kg and 65-90kg. The full-price feed is prepared according to the following feed formula. Various components are mixed and pulverized by conventional methods to make powdered feed. , ad libitum to feed to slaughter.

[0104] Feed formula for piglets at 10-35kg stage: 590 parts of corn, 100 parts of secondary powder, 175 parts of soybean meal, 80 parts of corn DDGS, 13 parts of soybean oil, 3.6 parts of lysine, 0.4 parts of methionine, 0.3 parts of threonine, 0.2 parts of tryptophan 13 parts of calcium hydrogen phosphate, 15.5 parts of stone powder, 4 parts of sodium chloride, 5 parts of vitamins and trace eleme...

Embodiment 3

[0112] In order to verify the effect of the feed of the present invention on improving the growth performance of Licha black pigs, the technical department of the applicant company conducted a feeding test on 120 black pigs in the original breeding farm of Licha black pigs in June 2016. The growth cycle of Licha black pigs is divided into three stages: 10-35kg, 35-65kg and 65-90kg. The full-price feed is prepared according to the following feed formula. Various components are mixed and pulverized by conventional methods to make powdered feed. , ad libitum to feed to slaughter.

[0113] Feed formula for piglets at 10-35kg stage: 590 parts of corn, 100 parts of secondary powder, 175 parts of soybean meal, 80 parts of corn DDGS, 13 parts of soybean oil, 3.6 parts of lysine, 0.4 parts of methionine, 0.3 parts of threonine, 0.2 parts of tryptophan 13 parts of calcium hydrogen phosphate, 15.5 parts of stone powder, 4 parts of sodium chloride, 5 parts of vitamins and trace elements p...

Abstract

The invention provides a feeding method for improving the production performance of Licha black pigs. The feeding method comprises the step of providing a complete feeding program and product system for growth development stages of the Licha black pigs, so that the average daily gain of the Licha black pigs can be effectively increased, the growth speed is increased, the growth period of the Lichablack pigs is effectively shortened, and the feed to gain ratio is lowered; meanwhile, waste of feed resources is lowered, and the cultivation cost is lowered; meanwhile, nitrogen discharge of the Licha black pigs is lowered, and the contamination caused by Licha black pig feeding to the environment is lowered.

Description

technical field [0001] The invention belongs to the technical field of feed preparation, and particularly relates to a feeding method for improving the production performance of Licha black pigs. Background technique [0002] Licha black pig is an excellent local pig breed in Shandong Province. It is listed in the Shandong Provincial Livestock and Poultry Breeds Record, the National Livestock and Poultry Protection List and the National Livestock and Poultry Genetic Resources Protection Variety. It has strong adaptability, high fertility, resistance to roughage, Strong resistance to stress, not easy to be infected with infectious diseases and good meat quality. With the rapid development of scale and standardization of the pig industry, the breeding scale of Licha black pigs is also increasing. However, under the current feeding mode, Licha black pigs lack uniform and standardized feeding standards, and the proportion and level of nutrients in the commonly used feed formula...
