Problems solved by technology

[0011] Another significant problem with traditional herd management systems may be that females weigh less on average than males under the same management and sell for a lower price

Embodiment 1

[0046]An integrated herd management system (IS) was designed to evaluate the integration of early weaning and utilization of sexed sperm in a single calf heifer (SCH) system to enhance the value of non-replacement heifers. The program consists of five phases; Phases I, II, and III are the developmental stages of the heifer. Phase IV is the qualitative determination of the integrated system when the evaluation of the carcass comes out. Phase V is to determine the economics of the integrated system. Integrated IS can replace non-replacement heifers that are traditionally marketed. Traditional market sales of non-replacement heifers are defined as sales of TMS heifers on a live weight basis immediately after the traditional weaning age of approximately 7 months (200 days). Therefore IS is economical compared with TMS. IS combines reproductive factors such as estrus and feeding of heifers; therefore a copy of the replacement heifer means breeding and simply comparing these fact...

Abstract

The present invention provides an animal management system (27) that utilizes artificial insemination samples of isolated X-chromosome-bearing and Y-chromosome-bearing sperm populations to inseminate female animals (17), an animal management system (27) that can provide non-traditional harvesting or traditional sales (20) Replacement heifers provide an implementation of replacement options.

Description

technical field [0001] In general, herd management techniques utilizing separate populations of X-chromosome-bearing and Y-chromosome-bearing spermatozoa can be used in a wide variety of mammals. More specifically, it relates to an integrated herd management system utilizing segregated X-chromosome bearing sperm populations to increase the value of non-replacement heifers in single heifer systems. Background technique [0002] Economic pressure to increase the efficiency of beef cattle production has boosted the industry and prompted researchers to evaluate various production systems. A traditional herd management system that has received a lot of attention is the single heifer system (SCH). The system has the ability to utilize non-replacement females normally used for slaughter purposes. Comparisons with other cattle management scenarios from 1958 to 1986 with average production costs and returns on production show that the simulated SCH system is cost-effective. Howeve...
