Description

Composite piglet feed and production method thereof
Technical Field
The invention belongs to the technical field of feeds, and particularly relates to a compound piglet feed and a production method thereof.
Background
The diarrhea disease of pigs is a common disease in pig raising production, the symptoms mainly show diarrhea, live pigs often have vomiting and poor appetite, and serious dehydration symptoms can appear. The disease usually occurs in spring and winter, the disease stage is not uniform, and piglets are taken as a common group. Viral diarrhea and bacterial diarrhea can cause infection. Diarrhea, a non-infectious agent, is mainly manifested by: weaning adaptation of piglets, environmental change of the colony house and improper feeding. Once diarrhea occurs, the resistance of the pig is weakened, the balance of intestinal flora of the pig and the absorption of nutrition are directly affected, and even the pig dies.
The weaning time of piglets is generally 7-8 weeks. In the feeding process, if the piglets are weaned too early, the resistance of the piglets is not enhanced, and the normal growth is affected. The early weaning can lead the piglets to grow slowly, the feed absorptivity is reduced, the immunity is low, and diarrhea is very easy to occur. After weaning, the piglets are less in immunoglobulin absorbed from breast milk, and as the gastrointestinal functions of the piglets are not fully developed, the piglets have low immunity and cannot resist invasion of bacteria, and once the piglets are infected by the bacteria, diarrhea is easy to occur.
Diarrhea of piglets often occurs, and in order to better restore the health condition of the piglets, the existing feed for preventing the diarrhea of the piglets is common, but after the diarrhea of the piglets, a feed which is more suitable for the current health condition of the piglets is needed.

Comparative example 9
A compound piglet feed is prepared by substituting herba Avenae Fatuae for rhizoma Dioscoreae in comparison with example 6, and the rest is the same as in example 6.
Comparative example 10
A compound piglet feed is prepared from rhizoma Dioscoreae instead of herba Avenae Fatuae in example 6, and the rest materials are the same as those in example 6.
The following tests were performed on examples 1-6 and comparative examples 1-10:
96 piglets were randomly divided into 16 groups, 6 piglets were fed with the feeds prepared in examples 1-6 and comparative examples 1-10, respectively, with a test period of 100d.
Test example 1 growth Properties
The pigs were weighed on empty stomach in each repeat basis on day 07:00 of start and end of test (12 h of cut before weighing). After the test, the repeated feed intake of the control group and the test group is counted, and the average daily gain, the feed-weight ratio and the number of piglets suffering from diarrhea are calculated, and the obtained results are shown in Table 1.
TABLE 1
Test set Average daily gain/kg Ratio of material to weight Number of diarrhea
Example 1 0.54 1.32 0
Example 2 0.57 1.29 0
Example 3 0.56 1.25 0
Example 4 0.62 1.36 0
Example 5 0.58 1.34 0
Example 6 0.57 1.28 0
Comparative example 1 0.32 1.94 2
Comparative example 2 0.44 1.73 2
Comparative example 3 0.32 1.75 1
Comparative example 4 0.39 1.76 2
Comparative example 5 0.38 1.84 1
Comparative example 6 0.34 1.44 0
Comparative example 7 0.32 1.52 1
Comparative example 8 0.44 1.60 1
Comparative example 9 0.50 1.63 1
Comparative example 10 0.46 1.48 0
As can be seen from Table 1, the compound piglet feeds provided in examples 1 to 6 of the invention have better average daily gain and feed-to-weight ratio, have higher piglet absorption efficiency, and compared with the feeds provided in comparative examples 1 to 10, the feeds provided in examples 1 to 6 have no piglet diarrhea, thus indicating good prevention and treatment effects on piglet diarrhea.
