Embodiment 1
[0023] 1. A beef cattle breeding method, comprising the following steps:
[0024] 1) Selection of fine-bred beef cattle
[0025] Bulls are selected from Simmental cattle, cows are selected from Luxi cattle, and 100 cows are selected.
[0026] 2) Feeding of cows
[0027] Cows are fed in isolation before estrus. They are fed three times a day and watered once in the morning and afternoon. The formula for the feed in the morning is whole plant corn silage, ammoniated wheat straw, alfalfa hay, oat hay, sugar beets and formula feed at noon. The formulations of feeding and night feeding are whole plant corn silage, ammoniated wheat straw, alfalfa hay, forage sugar beet and formula feed.
[0028] 3) Breeding method
[0029] For cows that are about to enter the estrus period, induce estrus. The method of inducing estrus is to inject 0.6 micrograms / head to the cows intramuscularly to promote Pai No. 3, and intramuscularly inject prostate gland according to the standard of 0.3 mg / hea...

[0034] 1. A beef cattle breeding method, comprising the following steps:
[0035] 1) Selection of fine-bred beef cattle
[0036] Bulls are selected from Simmental cattle, cows are selected from Luxi cattle, and 200 cows are selected.
[0037] 2) Feeding of cows
[0038] Cows are fed in isolation before estrus. They are fed three times a day and watered once in the morning and afternoon. The formula for the feed in the morning is whole plant corn silage, ammoniated wheat straw, alfalfa hay, oat hay, sugar beets and formula feed at noon. The formulations of feeding and night feeding are whole plant corn silage, ammoniated wheat straw, alfalfa hay, forage sugar beet and formula feed.
[0039] 3) Breeding method
[0040] a. Induce estrus for cows that are about to enter the estrus period. The method of inducing estrus is to inject intramuscular injection of prostaglandin according to the standard of 0.85 micrograms / head to cows, and intramuscularly inject prostaglandin according...

Abstract
The invention provides a beef cattle breeding method. The beef cattle breeding method comprises the following steps that firstly, beef cattle of improved variety are selected; secondly, cows are raised; thirdly, a breeding method is conducted, wherein a, estrus induction is conducted on the cows close to the estrus, the cows are observed very carefully early in the morning and at nightfall, and observation is conducted every 4-5 hours in the daytime for estrus situation identification, and an outer observation method and a rectal palpation method for the follicular development degree are adopted as the estrus situation identification method, and b, artificial fertilization is conducted through a rectum grasping semen deposition method at estrus stage III; fourthly, the cows are kept under the precious care as long as pregnancy is confirmed according to the situation that the cows are not in estrus any longer within two to three months after semen deposition, or through rectum pregnancy check so that the cows can breed healthy calves, and if false pregnancy is found, re-copulation measures are taken in real time to reduce the breeding loss. By means of the method, the physique of the cows is improved, and the breeding rate of the beef cattle is further increased through estrus induction.
Description
technical field [0001] The invention belongs to the technical field of livestock and poultry reproduction, and in particular relates to a beef cattle breeding method. Background technique [0002] my country's beef cattle industry started relatively late, and it only took a short time to become an industry, only more than 30 years, but the development speed is relatively fast. Over the past 30 years, my country's beef production has increased more than 30 times, making it the third largest beef producer in the world. [0003] The reproductive ability of beef cattle directly affects the economic benefits of beef cattle farms, and it is also a necessary guarantee for the good development of beef cattle farms. With the development of the beef cattle industry, large-scale beef cattle farms are increasing, but their fecundity tends to decline. Beef cattle in farms often show no estrus, no obvious estrus symptoms, prolonged estrus, slow ovulation, decreased conception rate and Sy...
