Problems solved by technology

Lactating piglets are quite different from post-weaning piglets and growing-finishing pigs in terms of growth and development, material metabolism, digestive system, and immune system functions. Therefore, it has a regulatory function for adult pigs such as post-weaning piglets and growing-finishing pigs. Feed additives are often not ideal for performance regulation of suckling piglets
By adding functional additives to suckling piglet feed, the regulation effect is often affected due to the restriction of digestion and absorption function and safety of suckling piglets
At present, there is no research report on forsythia or its extracts in improving nutrient digestibility of pregnant and lactating sows, bone quality and intestinal morphology of suckling piglets

Embodiment 1

[0032] Example 1 Application of the plant extract containing the active ingredient of forsythia in pig breeding

[0033]Select 50 sows (Landrace × Large White, parity 2-4) at 85 days of gestation, divide them into 2 treatments (experimental group and control group) according to parity, body weight and backfat thickness, and each treatment has 25 replicates , 1 sow for each replicate;

[0034] Control group: only fed the basal diet (the basal diet of sows in late pregnancy or lactating sows), without adding any plant extracts.

[0035] Experimental group: add plant extracts according to the dose of 100mg / kg basic ration feed, from the 85th day of pregnancy to the end of lactation 21 days, feed the feed containing plant extracts, the formula of plant extracts is as follows: Arthinin 17mg, Forsythin 82mg, Forsythia A 41mg, Forsythiaside A 17mg; the preparation method of the plant extract is as follows:

Embodiment 2

[0050] Example 2 Analysis of Effects of Plant Extracts on Bone Quality of Suckling Piglets

[0051] The test group in embodiment 1 and the 21 day suckling piglets of control group sows were carried out bone quality analysis, and analysis project and analysis result are as shown in table 3, compare with control group, the test group that adds plant extract in the diet The tissue weight of the femur and tibia of suckling piglets increased significantly (P<0.05), the area of ​​piglet femur and the peak load (Peak Load) had a significant increase trend (P=0.07), and the height and length of piglet tibia increased significantly The width of the tibia was significantly increased (P<0.05), and the height and width of the piglet femur were significantly increased (P<0.05).

Embodiment 3

[0055] Example 3 Analysis of Effects of Plant Extracts on Intestinal Morphology of Suckling Piglets

[0056] The 21-day suckling piglets of the test group and control group sows in Example 1 were analyzed for intestinal morphology, and the analysis items and analysis results are shown in Table 4. Compared with the control group, the test of adding plant extracts in the diet The villus height and the ratio of villi height to crypt depth (villus height / crypt depth) in the jejunum of suckling piglets in the group were significantly increased (P<0.05). The increase of villi height and villus height / crypt depth in piglets' intestines is beneficial to improve the intestinal absorption of nutrients and intestinal immune barrier function of suckling piglets.

Abstract

The invention relates to the technical field of livestock breeding, and in particular relates to an application of forsythia active ingredients in sow nutrition, piglet bone quality and intestinal tract improvement. The invention discovers that a plant extract containing forsythia active ingredients comprising forsythia aglycone, forsythin, Lianqiaolan A and forsythiaside A can effectively enter bodies of suckling piglets through placentas and breast milk of sows, and through addition of the plant extract formed by compounding forsythia aglycone, forsythin, Lianqiaolan A and forsythiaside A into daily feed of the sows, bone quality of the suckling piglets can be obviously improved, and the intestinal form of the suckling piglets can be effectively improved. Meanwhile, the plant extract canobviously improve nutrient digestibility of pregnant and lactating sows, provides a new method for improvement of bone quality and intestinal tract functions of the lactating piglets and nutrient utilization of the pregnant and lactating sows, and has a good market application prospect.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, in particular to the application of the plant extract forsythia active ingredient in the nutrition of sows and the improvement of bone quality and intestinal tract of piglets. Background technique [0002] Lactating piglets refer to the piglets from sucking after birth to before weaning. It is one of the important periods in the growth and development of pigs. Its growth performance and health status directly affect the performance of breeding pigs and fattening pigs. Lactating piglets are quite different from post-weaning piglets and growing-finishing pigs in terms of growth and development, material metabolism, digestive system, and immune system functions. Therefore, it has a regulatory function for adult pigs such as post-weaning piglets and growing-finishing pigs. Feed additives are often not ideal for performance regulation of suckling piglets. By adding functional additives to ...
