Problems solved by technology

But producing one or two babies is not conducive to large-scale production and reduces its production efficiency
On the other hand, due to the limited nutrition provided by the female animal, four litters are not conducive to the survival of lambs, and additional feeding is required, which increases labor and economic costs.

Embodiment 1

[0022] This example takes pregnant female animals as the research object to illustrate the method of the present invention.

[0023] Select 120 female Hu sheep of the same strain, similar in weight, and ready to be bred in estrus, and complete the mating work within three days (one in the morning and one in the evening). Group 1 and experimental group 2 were fed diets supplemented with different levels of folic acid, and the feed intake of each treatment was kept the same, as shown in Table 1.

[0024] Table 1 The levels of folic acid supplemented in different groups of diets

[0025]

[0026] Note: DMI in Table 1 is dry matter intake.

[0027] After the mating is completed, feed according to the treatment, 16-18 days old to test anti-estrus, and remove the non-pregnant female animals; after the mating is completed, use B-ultrasound to further test the mating results at the age of 30 days, and then remove the non-pregnant female animals again according to the B-ultrasound ...

Abstract

The present invention provides an application of folic acid in improving a lamb producing rate of female animals. A specific operation mode is as follows: the folic acid is used for feeding from the breeding of the female animals and through the whole pregnancy period until lambs are born. The folic acid can increase the lamb producing rate of the female animals and increase the birth weight of the offspring lambs, thereby improving the production efficiency. At the same time, the folic acid can also improve the postpartum body condition of the female lambs, promotes postpartum recovery, thusensures the healthy growth of the lambs, and is convenient in operation and remarkable in economic benefits.

Description

technical field [0001] The invention relates to animal husbandry, in particular to the application of folic acid in improving the lambing rate of dams. Background technique [0002] Folic Acid, a B vitamin 9 , is a water-soluble vitamin that was first synthesized in 1945. As a carrier of one-carbon units, folic acid plays an important regulatory role in the development of the body, especially during pregnancy. Early medical research results showed that folic acid supplementation during pregnancy can effectively prevent fetal neural tube defects (Oakley, 1997), and later found that folic acid also plays a role in some congenital malformations, vascular diseases, metabolic diseases and tumors in offspring. important role. Studies have found that injecting 150 μg of folic acid into eggs on the 11th day of incubation can promote embryonic development (Liu et al., 2016). Therefore, the supply of folic acid during pregnancy plays an important role in fetal development. [000...
