Problems solved by technology

In view of the unique physiological and nutritional characteristics of heavy-parity sows, it is unscientific to use lactating sow feed to attack tires, because breast-feeding feed itself has high energy, high protein, and low crude fiber level, so using lactating feed to attack tires is prone to Unbalanced nutrition leads to problems such as constipation, long labor, uneven birth of piglets, and strong oxidative stress in sows

Embodiment 1-2

[0031] The raw material types and proportions of the pregnancy feed, tire tapping feed, and lactation feed for multiparous sows are shown in Table 1 below. The first stage refers to: sows are pregnant until 84-89d, and the second stage refers to : 85-90d to sow farrowing, the third stage: sow lactation period.

[0033]

[0034]

Embodiment 3-5

[0036] The type and consumption of the pregnancy feed of the embodiment of the present invention 3-5, breast-feeding feed are basically consistent with embodiment 2, and the fetal tapping feed of embodiment 3-5 is as shown in table 2 below:

[0037] Table 2 Fetal feed for sows in the second stage (kg)

[0038]

experiment example 1

[0042] In the experiment, 80 Xinmei binary hybrid multiparous sows (Landrace × Large White) with the same parity, similar weight and body condition, healthy and disease-free, and the same or similar expected date of farrowing were selected and randomly divided into two groups (Group A and Group B) , 4 replicates per group, 10 pigs per replicate. The sows are raised in the gestation house, and the sows are transferred from the gestation house to the farrowing house 7 days before the expected farrowing date, and the farrowing bed is used to feed online in the house, and the lactation period is 26 days.

[0043] Group A adopts the "sow two-stage nutrition" mode of the gestation feed and the lactation feed of Comparative Example 1, and the B group adopts the "sow two-stage nutrition" mode of the pregnancy feed, the fetal feed, and the lactation feed of Example 5. Sows were fed in three-stage nutrition" mode, and the feeding mode was applied in accordance with "Table 3 Sow Feeding ...

Abstract

The invention provides a method for scientifically feeding multiparous sows through a three-stage nutrient scheme. The method comprises the following steps that the sows are fed with gestation feed from the gestation period of the sows to 84-89 days after the gestation period, the sows are fed with feed for increasing birth weight of piglets from the time 85-90 days after the gestation period to the delivery period, the sows are fed with lactation feed in the lactation period, and then the method is completed. The sow three-stage nutrient scheme design can systematically promote production performance of the sows and suckling piglets.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a method and application of a three-stage nutritional scheme for scientifically raising multiparous sows. Background technique [0002] The nutritional supply of sows is very important for the modern breeding industry in the process of raising pigs, because sows are the source of raising pigs. In my country, the feeding method for multiparous sows is generally that sows are fed from mating. Feed for pregnant sows, fed until 84-89 days of pregnancy; from 85-90 days in late pregnancy to delivery, which is called the "heavy pregnancy period" of sows, and sows use lactating sow feed during the heavy pregnancy period , that is, "tapping" the sows to enhance nutrition; sows use feed for lactating sows from delivery to the end of lactation. [0003] Therefore, from the perspective of nutrition, there are only two kinds of nutritional materials for a sow production cycle, includin...
