What are the major factor affecting 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 are two diseases that could impact reproductive efficiency in cattle?
The most common reproductive diseases in cattle are brucellosis (Bang’s disease); leptospirosis; infectious bovine rhinotracheitis (IBR) and bovine virus diarrhea (BVD) complexes; vibriosis; and trichomoniasis.
What causes infertility in farm animals?
Infertility in farm animals is due various causes such as nutrition, physiological disturbances and infectious causes, which may work separately or in combination. Economic losses can be considerable, both in terms of the cost of keeping a cow and the lost cash opportunity from fewer calves available to market.
What are the factors that affect breeding?
These include: libido, mating ability, serving capacity, and social dominance. These factors are only evaluated by watching the herd bull during the breeding season.
How would you improve breeding efficiency in your herd?
Take advantage of technology, including breeding indicators, to improve reproductive results
- 19.5 percent of operations take advantage of semen evaluation.
- 18 percent palpate for pregnancies.
- 14.3 percent body condition score.
- 7.9 percent use estrus synchronization.
- 7.6 percent use artificial insemination (A.I.)
What is infertile animal?
Failure of any single functional event in either sex leads to infertility or sterility. The ultimate manifestation of infertility is failure to produce offspring. In polytocous species, a subnormal number of offspring also constitutes infertility. In females, infertility may be due to: failure to cycle.
What are the factors to consider in breeding farm?
Selecting breeding stock
- Availability.
- Genetics (including fecundity).
- Health.
- Market acceptability.
- Quality control.
What affects animal reproduction?
The main environmental factors influencing animal reproduction are temperature, humidity, amount and distribution of rainfall, solar radiation and photoperiod, nutrition, productive system management, social interactions among individuals within the same population, predator-prey interactions, parasite- and pathogen- …
