Description

Feeding method of Luchuan pigs
Technical Field
The invention belongs to the technical field of livestock breeding, and particularly relates to a feeding method of Luchuan pigs.
Background
The Luchuan pig is a local pig in Luchuan county, belongs to a geographical sign of agricultural products in China, and is also one of eight local excellent pig breeds in China. It is small in birth weight, small in weaning weight and slow in intestinal tract development. In the breeding process, in order to improve the breeding efficiency of sows, 21-day weaning is generally adopted at present, because the weaning is early, the intestinal pressure of the Luchuan pigs is higher, and the weaning stress is easily generated. When the piglets are weaned, weaning stress is easy to occur, so that intestinal tracts of the piglets are damaged, and the digestion and absorption capacities of the piglets are weakened, thereby affecting the growth of the piglets.
At present, farmers see that the skin and the weight of weaned piglets are too heavy, and generally think that the piglets need to be continuously fed with high-protein piglet feed in the piglet stage for meeting the requirements of protein and increasing lean meat; with the increase of the age of the day, the protein content in the feed is gradually reduced. Although the feeding mode can lead the piglets to grow faster in the early stage, the piglets are very easy to cause diarrhea and intestinal tract injury, the intestinal tract recovery is slow, the growth is slow, and the later growth speed of the piglets is seriously influenced.
Therefore, a feeding method for Luchuan pigs is urgently needed, which can relieve intestinal pressure, reduce diarrhea rate of piglets and improve the growth speed of the piglets.

product effectiveness testing
The influence of the feeding method on the diarrhea condition, the growth performance and the slaughter time of the Luchuan piglets is researched.
(1) Experimental piglets and groups
300 Luchuan pigs of 21 days old, initial weight (5.8 +/-0.8) kg and good growth condition are selected in the test, the pigs are randomly divided into 10 groups, each group has 3 columns and 10 columns, the test period is from weaning to 200 days, the feeding conditions are shown in the following table 1, and the specific results are shown in tables 2, 3 and 4.
TABLE 1 grouping and materials used case
Figure BDA0003687001270000101
Figure BDA0003687001270000111
Note: the compound feed 311 for the Haima group Haima brand suckling pigs has the protein content of 18.5 percent; the Hailai group Haila brand suckling pig compound feed Hailai milk has the protein content of 16.5 percent.
TABLE 2 Effect on piglet growth Performance

TABLE 4 Effect on piglet diarrhea Rate
Item Group A Group B Group C Group D Group E Group F Group G Group H Group I J group
First stage 7.92 1.43 0.82 7.21 3.32 9.11 2.57 8.85 3.75 9.66
Second stage 0.41 0.25 0.28 0.22 0.36 0.21 0.28 0.19 0.33 0.20
The third stage 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.01 0.00 0.00
The result shows that the diarrhea rate of piglets can be obviously reduced by finishing feeding the low-protein feed in the first stage after the Luchuan pigs are weaned, but the growth performance is influenced to a certain extent; but the second phase is fed with high protein feed and finally the weight is better at the end of the second phase. The first stage low protein feed is matched with the second stage high protein feed, and the growth of the piglets can be compensated in the second stage, so that the piglets can be promoted to grow quickly; in the third stage, the feed-meat ratio and the end weight data of the piglets in the low-protein-first and high-protein-second modes are superior to those of the piglets in the high-protein-first and low-protein-second modes, which shows that the feeding mode of the low-protein-first and high-protein-second modes has high absorption efficiency of nutrient substances. The comprehensive whole-stage data show that the low-protein feed is fed to the Luchuan pigs in the first stage after weaning, and then the high-protein feed is fed to the Luchuan pigs in the second stage, so that the diarrhea rate of the weaned piglets can be obviously reduced, the intestinal health of the piglets is improved, the requirement of the piglets on the rapid growth protein is met by feeding the high-protein feed in the second stage, and the better daily gain and the feed conversion ratio in the whole growth stage are finally ensured.
