    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.

• 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).

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.

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.

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.
