Problems solved by technology
However, when ewes give birth to two lambs or multiple lambs, the birth process is prone to be too long, and the ewes have insufficient productivity in the latter part of the birth process, resulting in the death of lambs by suffocation or increased risk of birth canal infection in ewes
The existing technologies for dealing with prolonged labor are mainly artificial midwifery or injection of oxytocin (OXT). Midwifery is required if the ewe fails to produce a lamb within 30 minutes after the amniotic membrane ruptures. Midwifery can easily damage the ewe’s birth canal. If the midwifery is not done properly will cause the lamb to die

Embodiment 1
[0021] The production process of the sheep farm is grouped and batch production. According to the production process, one batch is selected to carry out the test. The ewes of this batch are randomly divided into 4 treatment groups, and each group of ewes is subjected to 1 treatment. 4 treatments, respectively: control group (without CAR), CAR1 group (with carnosine 200 mg / animal / day), CAR2 group (with carnosine 400 mg / animal / day), CAR3 group (with carnosine 600 mg / animal / day) / day), the addition time is the last 15 days of gestation (135 days of gestation to parturition), and the CAR is mixed and fed in TMR. Among them, the ewes are small-tailed Han sheep, Hu sheep and crossbred ewes of Xiao-tailed Han sheep or Hu sheep, and the parity is 2 to 3 litters. The carnosine (L-carnosine, CAR) selected for the test in this example is a food-grade raw material with a purity of 99%, purchased from Anhui Zhongnan Biotechnology Co., Ltd.

The invention provides application of carnosine in shortening the birth process of female animals. 15 days before delivery of the pregnant female livestock, 200-600 mg of carnosine is added into the feed every day for feeding each female livestock. The invention provides a novel application of carnosine, and the carnosine is used for shortening the birth process of female animals, shortening the delivery time of the animals, improving the oxidative stress level of parturient female animals, increasing the oxytocin level and reducing the stillbirth rate of the female animals caused by suffocation death due to retention in the birth canal in the delivery process.
Description
technical field [0001] The invention belongs to the technical field of feed additives in breeding industry, and particularly relates to the application of carnosine in shortening the birth process of female animals. Background technique [0002] Carnosine (L-carnosine, CAR) is a natural dipeptide with strong polarity, only soluble in water and insoluble in any organic solvent, because of its antioxidant properties, scavenging free radicals, chelating with transition metals, neuroprotection, It has the functions of promoting wound healing and anti-aging, so it has a wide range of application prospects in the fields of medicine, food, health care and so on. For example, the transparency of carnosine to the cloudy human eye lens is enhanced, and the use of carnosine-based antioxidant preparations can treat senile cataracts. At the same time, carnosine is also a sensor of olfactory nerves, which can promote wound healing, and is especially used in oral medicine for surgical tre...
