Embodiment 1

[0018] The screening of embodiment 1 Chinese herbal medicine preparation

[0019] Take 14 traditional Chinese medicines such as dried ginger, kudzu root, licorice, astragalus, andrographis paniculata, Codonopsis pilosula, Pulsatilla chinensis, woody fragrance, gardenia, honeysuckle, myrobalan, raw land, isatis root, and plantain seed, soak them in 10 times the water for 20 minutes, and decoct them After 20 minutes, pour out the liquid medicine, add water and decoct for another 20 minutes, combine the two liquid medicines, concentrate, centrifuge and dilute to a crude drug concentration of 1g / ml, sterilize and store at 4°C for later use.

[0020] Use a sterilized cotton swab to dip in pig feces Escherichia coli liquid (with a bacterial content of 10 8 cells / ml), inoculate 3 times evenly on the surface of the common agar plate, rotate the plate continuously to make the bacterial solution uniform, and finally smear 1 circle along the inner edge of the plate. Use a sterilized met...

Embodiment 2

[0024] The impact of embodiment 2 Chinese herbal preparations on the number of Escherichia coli in sow manure

[0025] According to the results of Example 1, compound Chinese herbal medicine preparations were made according to different weight ratios. After pulverization, the amount of 400g / kg was added to the feed for late-gestation sows, and each test group was fed with 25 late-pregnancy sows. Pigs, another 25 late-gestation sows were used as controls (not fed with Chinese herbal medicine preparations), and their feces were collected after feeding for 10 days, and then the number of E. coli in the feces was determined.

[0026] Test group 1: the weight ratio of dried ginger, kudzu root, licorice and astragalus is 1:1:2:1.

[0027] Test group 2: the weight ratio of dried ginger, kudzu root, licorice and astragalus is 1:3:2:4.

[0028] Test group 3: the weight ratio of dried ginger, kudzu root, licorice and astragalus is 2:1:2:3.

[0029] Test group 4: the weight ratio of dr...

Embodiment 3

[0035] Example 3 Effect of expanded flaxseed on the antioxidant capacity of serum of farrowing sows

[0036] The dietary nutrient standards of the control group and the experimental group were the same, and the dietary ration of the experimental group used expanded flaxseed on the basis of the control group. 5 sows at the age of 84 days of gestation were selected respectively, fed to the experimental group and the control group respectively, blood was collected on the day of delivery, centrifuged, and the supernatant was taken to measure the activities of superoxide dismutase and catalase and C dialdehyde content.

[0037] The results are shown in Table 3, indicating that the expanded flaxseed can improve the antioxidant capacity of sows.

Abstract

The invention discloses a compound feed for sows during the perinatal period. The compound feed for sows during the perinatal period comprises the following ingredients: corn, soybean meal, beet meal,soybean peel, puffed linseeds, soybean oil, super steamed fish meal, sugarcane molasses, calcium hydrogen phosphate, stone powder, sodium chloride, a compound premix for sows during the perinatal period, a hydroxyl-vitamin D3 premix, a Chinese herbal medicine preparation, a compound acidifying agent, L-lysine sulfate, choline chloride, isommaltooligosaccharides, threonine, methionine, phytase, and ethoxyquin. The compound feed for sows during the perinatal period disclosed by the invention is capable of reducing usage of antibiotics in a breeding process, maintaining intestinal health and birth canal health, and decreasing constipation so as to effectively shorten the production process of sows as well as reduce incidence of inflammation; and thus, reproductive performance of sows can befurther improved so as to achieve reduced weak piglet rate and increased weaning weight of the piglets, as well as improved estrus rate of sows within 7 days of weaning.

Description

technical field [0001] The invention belongs to the field of animal feed, in particular to a perinatal compound feed for sows and a preparation method thereof Background technique [0002] The perinatal period of sows refers to the period from 7 days before delivery to 7 days after delivery. It is a very special and critical period in the reproductive cycle of sows. It has special influence. The performance of sows in this period will affect the pig herd final production level. Sows have a long perinatal period (heavy birth period, parturition, lactation), rapid changes (predominant progesterone during heavy pregnancy, oxytocin during parturition, postpartum prolactin), and many problems (long labor, Postpartum fatigue, slow recovery of appetite, persistent lochia, stress oxidation), perinatal problems are very common problems in hybrid lean sows under the modern pig raising model. In order to increase birth weight, pig farmers generally use lactating sow feed to feed peri...
