Description

Additive for improving production performance of sows, preparation method of additive and mixed feed containing additive

Technical Field

The invention relates to the field of feed additives, in particular to an additive for improving the productivity of sows, a preparation method thereof and a mixed feed containing the additive.

Background

The production of the sows is an upstream link of the production of the live pigs, and the litter size of the sows and the survival rate of suckling piglets are related to the benefit of the whole pig raising production. In addition to the relationship with genetic factors, the reproductive performance of sows is also an important factor, and the birth weight, weaning weight, survival rate and the like of piglets are influenced by nutrition.

The gestation period is an important stage of sow production, and good management of the gestation period can make full preparations for gentle and lactation. During this period, in addition to ensuring that the sow ingests sufficient nutrients to promote embryo survival, growth and development, good nutritional reserves are ensured to reduce weight loss during lactation, thereby maintaining good body conditions during reproduction and promoting development of mammary tissue, thereby ensuring adequate lactation during lactation. The lactation period is very important for both the female pig and the piglet, and the back fat thickness during the delivery and the back and waist loss during the lactation period can influence the time interval from weaning to oestrus and the litter size of the female pig; the good and bad production performance of the suckling piglets is related to the weanling stress resistance of the piglets and the production performance of the piglets in the fattening period. Therefore, the feeding management, especially the nutrition management, in the gestation period and the lactation period is very important for improving the production performance of the piglets.

In view of the above, the present invention is particularly proposed.

By adopting single-factor experimental design, 168 sows with 1d of pregnancy are randomly divided into 8 test groups according to the principle of similar fetal times and body conditions, each group has 3 repetitions, and each sow has 7 repetitions and is fed in a single column. Wherein test group I is used as a control group; experiment II-IIIV groups are experimental groups, and are added into feed respectively

The additives of examples 1-3 and comparative examples 1-4 were used in an amount of 1000 g/t.

The pregnant sow feed is fed from 1 st gestation day of the sow and is continued until 90 days gestation day, and then the sow feed is changed into the lactating sow feed until the 21 st lactating (weaning piglets) test is finished.

(2) Experimental daily ration and feeding management

The pregnant feed and the lactation feed of each group of sows are the same and are provided by pig farms, and the corn bean pulp type is taken as the main basic daily ration; the piglet creep feed is provided by a pig farm, and the protein is not less than 20 percent and the fat is not less than 6 percent.

The test sow after the breeding in the barren is transferred to a half-leaking floor limit fence of a gestational house and starts the test, and the cleanness, dryness, good ventilation and stable temperature (23-25 ℃) in the house are kept. Fed 2 times daily at 08: 00 and 17: 30 feeds, wherein the feeding amount in the pre-gestation period (1-30 d of pregnancy) is 2.0kg/d, the feeding amount in the middle gestation period (30-90 d of pregnancy) is 2.5kg/d, the feeding amount in the later gestation period (90 d of pregnancy-delivery) is 3.0kg/d, and the sows freely drink water. Transferring the test sow to a thoroughly disinfected farrowing house 1 week before the expected birth period; the lactating sows are raised in the full-leaking floor limit fence, and the clean and dry house, good ventilation and stable temperature (23-25 ℃) in the house are also kept. The sows can drink water freely, the vulva and the breasts of the sows are cleaned and disinfected by 0.1 percent potassium permanganate aqueous solution before delivery, and each nipple is squeezed and dredged. On the day of delivery, the feed was not given, 2.0kg was given at 1d after delivery, and 0.5kg was added daily until after 5d, they were allowed to feed freely. Feeding 4 times per day in the free feeding stage and keeping the feed in the trough slightly remained. Shearing tails, removing canine teeth and supplementing iron on the day of delivery of suckling piglets, starting girlfriend cutting and creep for piglets 7d after delivery, and keeping warm by using a 250-watt infrared heat preservation lamp. After the sows are delivered, the piglets can be cross-fed in the group according to the weight (the cross-feeding is completed within 12 hours after the sows are delivered), so that the number of the piglets in each litter (10 or 11) is ensured, and the weight distribution is uniform; other feeding management and immunization procedures were performed following the pig farm management system. The temperature and humidity were recorded every day, and the health of the sows was observed and recorded.

Note: the difference of letters among different groups means significant difference (P < 0.05), the same means insignificant difference (P > 0.05)

TABLE 2 Effect on weaning of piglets

As can be seen from the data test comparison data in the table 1, compared with the control group without the additive, the pregnant sows in the experimental group are obviously superior in farrowing survival rate, healthy litter size, average weight of piglets and other data, so that the additive can improve the production performance of the pregnant sows;

meanwhile, as can be seen from the comparison of the test data in table 2, the nutrition supply of the sows in the lactation period can be effectively improved by using the additive feed, so that the survival rate of the piglets is improved, and the weight gain of the piglets is promoted.

Meanwhile, as can be seen from the comparison of the effects of the additives in the examples and the comparative examples, better effects can be obtained only by using the moringa oleifera powder, the complex enzyme preparation, the active oligosaccharide, the L-carnitine, the eucommia ulmoides extract, the scutellaria baicalensis and other components in a matching manner.
