Embodiment approach

[0031]The beef cattle breeds commonly raised in Henan Province: Xianan cattle, Xiza cattle, Xiaza cattle, and Benza cattle were selected as experimental comparisons. Data on the reproductive status of several local beef cattle breeding farms were extracted for comparison.

[0032] A breeding method for improving the reproductive rate of beef cattle, comprising the following stages:

[0033] (1) Adjustment of herd structure. At the end of the year, the cow herd structure is 80% for basic cows (18-24 months old), 10% for back-up cows (over 1 year old), and 10% for bred cows (under 1 year old). ;

[0034] (2) Breeding controls, including:

[0035] (a) Select high-quality breeding bulls, select healthy bulls from two aspects of physical appearance and production performance, collect semen, test, and freeze;

[0036] (b) Nutrient supply for cows. From estrus to lactation, 100mg of zinc sulfate per kilogram can be added to the cow’s diet according to the weight of the cow. Starti...

Abstract

The invention discloses a breeding method for improving the reproductive rate of beef cattle and relates to the technical field of livestock breeding. The method comprises the methods of (1) cattle herd structure adjustment, wherein the adjustment at the end of a year is 80% of basic cattle, 10% of reserved cattle and 10% of bred cattle, (2) breeding control including (a) the selection of high-quality breeding cattle, (b) the nutritional supply of female beef cattle, (c) reproductive disease control, (d) estrus identification and breeding insemination, (3) fetus protection after insemination including feeding management, environmental control and appropriate exercise, (4) pregnancy check and re-examination and secondary insemination, performing pregnancy check after 20 days to 1 month of female cattle insemination, and performing complementary insemination non-pregnant female cattle, and (5) delivery and postpartum care. According to the method, the purpose of improving the reproductive rate of the beef cattle is achieved by the strict control of the living environment of the pregnant cattle, timely insemination and post-natal care and the strengthened management of the aspects ofmaternal health, conception rate, and complementary insemination for non-pregnancy.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, in particular to a breeding method for improving the reproductive rate of beef cattle. Background technique [0002] Reproductive rate refers to the percentage of the number of weaned and surviving calves to the number of breeding cows in the whole group within a certain period of time. According to the various stages of the cow's reproductive process, the reproductive rate can be calculated from the following indicators, namely the mating rate, conception rate, parturition rate (calving rate) and calf survival rate. Therefore, the reproductive rate can be expressed by the following formula: [0003] Reproductive rate = mating rate × conception rate × farrowing rate × calf survival rate × number of litters born [0004] The mating rate refers to the percentage of cows participating in breeding this year to the number of suitable breeding cows in the herd, excluding cows with empty pr...
