Research Of Estrus Synchronization And Development Of Beef Cattle Breeding Management Software

For improved variety improvement of problems in the work of the Hunan beef cattle industry, The paper research frozen bull semen artificial insemination system base on estrus control, breeders in the computer management and frozen bull semen artificial insemination technology procedures, to preven stealing mating, leakage mating and improve coordination with breeders member the work efficiency and improve the breed improvement coverage through estrus forecast and estrus control, and through the timely detection and treatment of reproductive disorder to improve the utilization rate of cow breeding, to regulate the artificial insemination technology,we can implementation of the Regulations, improve the conception rate of artificial transmission precision. To the breeders member (or breed improvement station) work primarily, we further research on the following aspects:1. For the application of estrus control and computer management means, the status investigation and analysis of Hunan beef cattle breeding condition, and random sampling analysis of Hunan province in 2612 beef type cow reproductive performance and reproductive diseases:(1) the local yellow cattle (Xiangxi huang cattle and XiangNan huang cattle) accounted for the over all number of 74.5% cattle, Binhu buffalo 10.8% of the total, Limousin cattle, Simmental, Germany, Angus, Murrah buffalo hybrid cattle accounted for 14.7% of the total; (2) reproducible cows average age is 4.5 years old, the average was 2.2 Parity, the average first mating month age was 19.9 month, and breeding rate of 66.7%, abortion and still birth rate was 2.6%; (3) the cow reproductive disease proportion is about 6.4%, the main reproductive disease is endometritis, vaginitis, ovarian cyst; (4) growth of the ovary, in the normal estrous cycle of heifers proportion is 55.4%, ovarian quiescence period is 34.3%, other is 10.3%.2. In order to solve breeder member or of beef cattle cow breeding management, first developed by "the estrus control technology" and "mate work" based computer management software. The software consists of 6 modules:(1) Estrus control cooling function over time in today’s taskbar changes according to region, reproductive status, classification for ecasting barren cows, estrous control plan 1 PG method and treatment of reproductive disorder, automatic tracking and remind the next processing step;(2) The estrous information prediction function over time in today’s task barchanges according to region, forecast (including early estrus, postpartum estrus and estrus after mating) cattle breeding, breeders can understand the cattle estrus information in the first time, so as to inform farmers have the purpose of observation of estru within the specified time, solve the mating member work blindly passive problem; (3) other reminder function changes in today’s taskbar by region over time, a list of cattle breeding and other tasks, and print the task list, facilitating the centralized time, location batch execution of daily work;(4) information query function; (5) statistical analysis and reporting capabilities; (6) technical training functional. This paper takes "cow", "mating member" two key link based, developed a "estrus control technology" and "breeding member" in the computer management software, solve the breeding member application of estrus control technology, blind search and the number of simultaneous treatment of the problem of shortage of cattle; solves estrus control and frozen semen insemination technology application and promotion difficultly at present, and not available software to breeding members in beef cattle field.3.Various functions of beef cattle breeding management software to estrus control technology based application in demonstration, breeders member according to the propagation of management software for automatic formulation of estrus control scheme for operation, estrus control effect processing cow:normal estrous cycle cow estrus rate up to 90.5%[341/377], the conception rate up to 86.8%[296/341], estrus rate increased 29.1%, the conception rate of estrus cows increased 5.2% compared with the conventional approach, illustrated by computer than rectal examination can effectively judge the luteal phase; anestrus cows estrus rate, pregnancy rate of 87.5%[126/114],73.5%[144/196]. Through the application of the propagation of the software, can prevent the normal cows were missing, stealing mating and leakage mating with coordination, implementation of 1 PG estrus synchronization treatment method not rely on rectal examination on the estrous cycle of normal nonpregnant cows, on anestrus cows achieve early discovery, and earlier treatment, improves the work efficiency and quality improvement Cow Reproduction rate.4. Specification for artificial insemination in Hunan beef breeder member, combining the Hunan Province beef breed station "beef cattle frozen semen operation guide" and the Hunan province breeders member technician training materials, and all over the combination of breeders member technician level and practical situation, we made Hunan province Bovine Frozen Semen artificial insemination procedures operation. Procedures for the formulation of Hunan Province frozen bull semen artificial insemination technique include:the preservation and use bovine frozen semen thawing, cow estrus rules, estrus identify, time of insemination, insemination method, a pregnancy test, record, registration, equipment cleaning and disinfection methods applicable to the specific operating requirements, and can applying to the Hunan province of Bovine Frozen Semen artificial insemination.This paper through the investigation of Hunan beef cattle breeding status, research and development of beef cattle breeding management software, artificial insemination operating procedures standardized and simplified artificial insemination in beef cattle operation, thus speeding up Hunan beef breed improvement process, and have good social benefit through the promotion of application,.
