Problems solved by technology

Progesterone treatment for 14 days can achieve the purpose of estrus synchronization, but it affects the fertilization rate due to the weakening of sperm transport in the reproductive tract of cows, egg fertilization and cleavage
[0005] However, the use of hormone drugs before or during ovulation will cause drug residues in the dam and affect the future embryonic development, which will have a certain impact on the dam and the embryos to be bred

Embodiment 1

[0038] A method for synchronizing estrus in cattle, comprising the following steps:

[0039] (1) Choose a cow that is more than 2 months old after calving, with a medium fat condition, and determine that it is in the empty pregnancy period;

[0040] (2) Feed trace elements and microbial supplements to the selected cows every day for 5 days, and the feeding amount is 0.25% of the daily feed intake. The trace elements and microbial supplements are obtained by mixing the following raw materials: vitamin E24000IU , vitamin A 4.8 million IU, vitamin D 3 1.9 million IU, vitamin C 48g, vitamin B 2 3.5g, vitamin B 6 5.5g, vitamin B 12 0.4g, calcium palmitate 13.5g, linolenic acid 23g, amino acid chelated zinc 11g, lysine 24g, orotic acid 25g, sunflower seeds 2g, chromium picolinate (calculated as chromium) 2.2g, fatty acid calcium 2.5g, 12.5g of butter, 1.5g of selenium-enriched yeast, 0.65g of β-carotene, and 2g of iodine;

Embodiment 2

[0048] A method for synchronizing estrus in cattle, comprising the following steps:

[0049] (1) Choose a cow that is more than 2 months old after calving, with a medium fat condition, and determine that it is in the empty pregnancy period;

[0050] (2) The selected cows are fed with trace elements and microbial supplements every day for 3 days, and the amount of feed is 0.25% of the daily feed intake. The trace elements and microbial supplements are obtained by mixing the following raw materials: Vitamin E 20000IU , vitamin A 4.6 million IU, vitamin D 3 1.6 million IU, vitamin C43g, vitamin B 2 2g, vitamin B 6 3g, vitamin B 12 0.1g, calcium palmitate 17g, linolenic acid 25g, amino acid chelated zinc 14g, lysine 28g, orotic acid 28g, sunflower seeds 3g, chromium picolinate (calculated as chromium) 2.6g, fatty acid calcium 3g, butter 15g, selenium-enriched yeast 2g, β-carotene 0.8g, iodine 3g;

[0058] A method for synchronizing estrus in cattle, comprising the following steps:

[0059] (1) Choose a cow that is more than 2 months old after calving, with a medium fat condition, and determine that it is in the empty pregnancy period;

[0060] (2) Feed trace elements and microbial supplements to selected cow groups every day for 7 days, and the feeding amount is 0.25% of the daily feed intake. The trace elements and microbial supplements are obtained by mixing the following raw materials: vitamin E28000IU , vitamin A 5 million IU, vitamin D 3 2.2 million IU, vitamin C53g, vitamin B 2 5g, vitamin B 6 8g, vitamin B 12 0.5g, calcium palmitate 10g, linolenic acid 21g, amino acid chelated zinc 8g, lysine 20g, orotic acid 22g, sunflower seed 1g, chromium picolinate (calculated as chromium) 1.8g, fatty acid calcium 2g, butter 10g, 1g of selenium-enriched yeast, 0.5g of β-carotene, 1g of iodine;

Abstract

The invention relates to the technical field of livestock breeding and in particular relates to a cattle estrus synchronization method. According to the method, progesterone pessaries, PGF2alpha analogue and a cattle estrus synchronization traditional Chinese medicine composition consisting of Angelica sinensis, motherwort, processed rehmannia roots, Chinese yams, dates, glossy privet fruits, dutchmanspipe roots and radix ophiopogonis through reasonable matching are used together, times and conditions of different steps in a cattle estrus synchronization period are controlled, in addition, variation of hormone levels in cow bodies is sufficiently controlled, development and ovulation of ovarian follicle are promoted, and then an effect of estrus synchronization can be achieved; in addition, by adopting the method, a small amount of medicines are used before and in ovulation, so that a small amount of medicines are left in cow bodies, later embryonic development is slightly affected, and the method is a cattle estrus synchronization method which is based on both traditional Chinese methods and western methods and has a small amount of traditional Chinese medicine residues in cow bodies and embryos.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, in particular to a method for simultaneous estrus of cattle. Background technique [0002] Estrus synchronization refers to the use of certain hormone preparations to artificially control and adjust the process of the estrus cycle of a group of female animals, so that they can concentrate on estrus within a predetermined time. [0003] Simultaneous estrus can adjust the estrus, mating, pregnancy, and delivery of the herd to be carried out simultaneously within a certain period of time. The advantage of this is that the young animals are born at the same time, and the management and cultivation of the lactation period can be unified. The disadvantage of the scientific feeding and management of adult livestock is that there are many equipments used, and the work of the personnel is uneven throughout the year, so it needs to be well arranged. [0004] Cow estrus control technology began ...
