FAQ: What Are Goals For Reproductive Health In Livestock?

How can you improve the reproduction of a cow?


  1. Aim for cow condition to be score 3+ at calving.
  2. Maintain adequate pasture resources.
  3. Minimise or eliminate dry season lactation (weaning and mating management)
  4. Strategic use of supplements.
  5. Appropriate disease management.
  6. Bull management (condition and soundness)

How do you increase reproductive efficiency in dairy cattle?

Take advantage of technology, including breeding indicators, to improve reproductive results

  1. 19.5 percent of operations take advantage of semen evaluation.
  2. 18 percent palpate for pregnancies.
  3. 14.3 percent body condition score.
  4. 7.9 percent use estrus synchronization.
  5. 7.6 percent use artificial insemination (A.I.)

What is reproductive performance?

Reproductive performance. It is calculated as the number of cows that got pregnant divided by the number of cows that were eligible to get pregnant. It is a measure of the speed at which cows get pregnant after the voluntary waiting period.

What reproductive challenges do cows have?

On the present report, we focused on four reproductive challenges that are critical to cow-calf operations: delayed puberty, poor control of timing of ovulation, early and late embryonic mortality, delayed return to cyclicity after parturition.

How many years are cows fertile?

The data would indicate that cows are consistent in the rebreeding performance through about 8 years of age. A small decline was noted in 1983 as cows aged from 8 to 10 years of age. However the most consistent decline in reproductive performance was noted after cows were 10 years of age.

What are three methods of reproduction management?

Breeding Systems

  • Hand mating. This method involves selecting the buck/ram for the doe/ewe and mating them.
  • Pen breeding. In pen breeding, the buck/ram is put in a pen of does/ewes to facilitate their mating.
  • Artificial insemination (AI).
  • Out-of-season breeding.

What is reproductive efficiency in beef cattle?

Numbers that would define reproductive efficiency for most herds would include a 90% to 95% pregnancy rate, less than 2% abortion rate, and 65%, 88%, and 100% of the calves born by days 21, 42, and 65 of the calving season, respectively. Efficiency is synonymous with optimums, not maximums.

How can I increase my cows conception rate?

One of the ways of improving percent of cows breeding early in the breeding season is to use a short calving season (60-90 days). This ensures that many of the cows will have had an opportunity to cycle at least once prior to the start of the breeding season.

What are the causes of low breeding efficiency?

Evidence is presented which indicates that a low rate of fertilization and a high rate of embryonic mortality are the major factors causing the low seasonal breeding efficiency associated with high ambient temperature and humidity in lactating dairy cows.

What is reproductive efficiency and why is it important?

Reproductive efficiency plays a key role in the economic success of dairy herds, as it influences milk production per day of calving interval and culling policies [1].

What factors affect reproductive efficiency?

Two factors that contribute significantly to reproductive efficiency are conception rate and loss of pregnancy.

What is a calving rate?

Calving percentage is the pregnancy percentage minus any embryonic or fetal death loss. The current benchmark for these herds is 93.6 percent for pregnancy percentage and 92.9 percent for calving percentage. The benchmark is the average for all the herds through the last five years.

Why cow is not getting pregnant?

Anovulation, a term describing when cows fail to ovulate normally, can be a result of poor postpartum health but is also related to high milk production in the modern dairy cow. On average, anovulation persists in at least 20% of dairy cows beyond the common voluntary waiting period of 60 days (Wiltbank et al., 2010).

What are reproductive failure and its causes?

The most commonly recognized causes for reproductive failure are poor cow nutrition (energy and micronutrients); venereal diseases, such as trichomoniasis (trich) and vibriosis (vibrio); other infectious diseases, such as BVDV, IBR, and leptospirosis; bull infertility, disease and injury; and changes to breeding season

Why are cows so important?

Cattle have contributed to the survival of humans for many thousands of years, initially as animals our hunter-gatherer ancestors pursued for food, tools, and leather, and which farmers raised for the past 10,000 years or so as livestock for meat, milk, and as draft animals.
