Description

Suckling pig feed and preparation method thereof

technical field

The invention relates to the field of animal feeding, in particular to suckling pig feed and a preparation method thereof.

Background technique

Piglets are now weaned early to improve sow yield and economic benefits. Post-weaning piglets are prone to a series of symptoms such as growth retardation, diarrhea, coughing, emaciation, etc., and the piglets have high growth intensity, poor stress resistance, imperfect digestion of vegetable feed, and higher and more demanding requirements for feed. In order to solve this problem, the related technology proposes a suckling pig feed for weaned pigs. Since the digestive physiological characteristics of suckling pigs and the relationship between raw material collocation and nutritional level are not considered in this suckling pig feed, the proportion of vegetable raw materials is too large, and the protein level is too high. Antibiotics are added, but a large number of piglets will still have diarrhea, so the growth of piglets will be slow and the uniformity will be low, which will seriously affect the later growth and prolong the time for slaughter.

This suckling pig feed is usually used for feeding suckling pigs from the 7th day of birth to two weeks after weaning.

Feeding experiment:

The prepared suckling pig feed is used for feeding suckling pigs, and the growth status and health status of the suckling pigs are detected.

1. Test materials and methods

1. Experimental animals and experimental design

Select 60 Du piglets weaned at the age of 28 days, and randomly divide them into 2 groups according to the principle of body weight, sex, and litter. There are 5 replicates in each group, 6 pigs in each replicate, and the test period is 14 days.

Note: Du Dachang is also called "Sanyuan pig", so it is not difficult to imagine that Du Dada is produced by crossbreeding three kinds of pigs: Du Changbai, Landrace, Large White pig, and Large White pig is also called Da Ke.

2. Feeding management

The pigs are reared in mesh beds, the house temperature is kept at (22-25)°C, and the area of the pen is 2m×2m. Automatic feeding trough, nipple drinker. Powder feeding, free access to food and water. Deworming and immunization were carried out according to the routine management procedures of the pig farm. The first group is the control group, which is fed with high-grade rations from a certain company, and the second group is the experimental group, who designed formula basal rations for himself. The experiment was carried out in the same double-row closed pig house. The pigs were reared online, the house temperature was 25-28°C, they had free access to food and water, and deworming and immunization were carried out according to the routine procedures of the pig farm.

3. Detection indicators

(1) Ratio of daily weight gain to feed weight gain

The test period was 4 weeks. Individuals were weighed at the beginning of the test and before early feeding at the end of the 2nd week, and the feed was calculated by pen, and the average daily weight gain and feed weight gain ratio were calculated.

(2) Statistics on the number of diarrhea

Observe and record the diarrhea of piglets every day

2. Test results

Among them, the formula of a certain company's product is: in parts by weight, 60 parts of corn, 28 parts of soybean meal, 3 parts of whey powder, 5 parts of fish meal, and 4 parts of premix. The nutrients contained in the formula are 31% by mass of crude protein, 0.7% by mass of calcium, and 0.63% by mass of phosphorus.
