Use the following guidelines in the reproductive management of heifers: • Heifers should be grown to attain adequate size for breeding at 15 months of age. • Watch heifers for heat activity twice daily for a minimum of 20 minutes each. • Breed heifers to superior A.I. bulls known to produce few difficult births. Predation management. The main predation threat to the cattle industry is the wild dog. Protective behaviour by cows can be enough to deter attacks on calves although much depends on the health, condition and protectiveness of the cows. Producers should also undertake wild dog control activities on their property.

Percent of producers use this relatively new man-agement tool. It is encouraging to note that percent of producers feed replacement heifers separately from the rest of the herd, providing an opportunity to meet their unique nutritional needs more effectively.

Drivers of change in dairy herd health management include the significant increase in herd/farm size, quota removal (within Europe) and the increase in technologies to aid in dairy cow reproductive management.

Beef Reproduction Task Force. The Beef Reproduction Task Force came together as a group inarising from the need for extension personnel to effectively communicate to beef producers the latest information related to reproductive technologies.
the group established a short list of recommended protocols for beef heifers and cows, which. Complex sheep cervix causes reproductive techniques to be developed that are different from cattle, are more difficult to apply, are less effective and more costly.
Still, in good programs, we achieve the same rates of success for AI and ET in sheep as the North American cattle Size: 1MB. Achieving high reproductive performance in beef herds for a beef cow herd. Checklist • Compact calving (80% of cows calved in 60 days).
• A day calving interval. • Low culling rate (less than 5%) for barrenness. • Replacement heifers are bred from maternally tested AI bulls. •71 percent of beef cows on predominantly spring calving beef operations in the U.S. with 5 or more beef cows (or replacement heifers).
•75 percent of predominantly spring calving beef operations in the U.S. with 5 or more beef cows (or replacement heifers). Data for Part III: Beef Cow/Calf Health & Health Management were collected from However, increasing efficiency of beef production will hinge on the adoption and refinement of current and future reproductive technologies.

In a spring calving herd, cows should calve close to the time when grass begins to grow rapidly. This will maximise production from grazed grass, by far the most profitable feedstuff.
If most of the herd calve within a compact period of six to eight weeks, farmers will have more time to File Size: KB. Management of Replacement Heifers.
Heifers need to calve by 24 months of age to achieve maximum life-time productivity (Patterson et al., ), and heifers that lose a pregnancy or conceive late in the breeding season are not likely to have enough time in the subsequent breeding season to conceive.
Conversely, heifers. resulting from use of reproductive technologies are assessed in this review because these are indicators of the impact that use of these technologies has on improving genetics in beef cattle. Reproductive Technologies Introduction Only a brief overview of the reproductive technologies will be provided in Author: JE Kinder, JM Osborne, ME Davis, ML Day.
Breeding heifers two weeks before cows and feeding heifers separately from cows may help to reduce some of the problems associated with getting heifers bred on schedule. While most herds periodically experience a few abortions, abortion rates greater than 3% for cows and 6% for heifers would also be considered cause for serious concern based on.
BEEF SYSTEMS MANAGEMENT STRATEGIES: CALVING DATE SELECTION, ESTRUS SYNCHRONIZATION, AND POST-WEANING MANAGEMENT Benjamin Todd Tibbitts, M. University of Nebraska, Advisors: Richard N. Funston and Jim C.
MacDonald The objective of an invited review and four experiments was to evaluate. each year and culling up to 10% of the cows for poor reproductive performance, and this includes 5% of the herd that will never get pregnant, even though they are healthy.
Before discussing the effects of herd and feeding management on reproductive performance, it is important to. Dairy and beef producers should strive to increase reproductive efficiency as a key driver of economic efficiency in the sector. Reproductive efficiency, or "pregnancy rate," is defined as the proportion of cows eligible to be bred that become pregnant during an estrous cycle (or approximately 21 days), and which determines the calving to conception interval at the end of the voluntary waiting.
Featured Topics: Blaze N' Star | Episode 1: The Importance of Reproduction This video was designed to introduce the importance of reproduction in dairy cattle. Cows that do not become pregnant within the first days in milk have a greater chance of either being replaced or having reduced lifetime milk production.
Lactating dairy cows. Reproductive performance of the U.S. beef herd has not changed in the last 20 years, and beef cattle inventory in the U.S. has declined concurrently.
Global demand for red meat will continue to rise with rapid population growth and economic development. The overall goal of this proposal is to develop educational opportunities and nutritional strategies for improving beef cow reproductive.
calf systems. Reproductive management of the herd involves many factors, such as development of replacement heifers, postpartum interval and rebreeding of cows, and also management of gestation and delivery of the calf.

INTRODUCTION. Effective selection and management of replacement beef heifers has a positive influence of the reproduction efficiency of beef herds (Patterson et al, ).Purchasing or developing replacement heifers is a significant capital investment for producers; therefore, it is important for cattle producers to consider the economics of replacement heifers (Hughes, ).Cited by: 1.

These statistics do not bode well for the future economic and environmental sustainability of the national suckler cow herd. In this chapter the key elements of fertility and health management of spring-calving beef cow herds will be discussed.
My previous columns indicate that I don’t like over-developed heifers. Yes, you can get a lot of heifers pregnant the first time, but later breedings and calf performance might not be so good.
