Physiological Mechanisms Leading to Reproductive Decline in Dairy Cattle

نویسنده

  • Matthew C. Lucy
چکیده

Dairy cattle are inseminated and pregnancy is established during lactation. Therefore, lactation and the reestablishment of pregnancy must overlap. Unfortunately, recent changes in the genetics, productivity, and management of dairy cows have led to a decline in reproductive efficiency. Reproductive decline in dairy cows began in the mid-1980’s and may be continuing on modern dairy farms (Lucy, 2001).

Physiological Mechanisms Linking Reproduction to Nutrition in High-Producing Dairy Cows

Dairy cattle are inseminated and pregnancy is established during lactation. Therefore, lactation and the reestablishment of pregnancy must overlap. Unfortunately, recent changes in the genetics, productivity, and management of dairy cows have led to a decline in reproductive efficiency. Reproductive decline in dairy cows began in the mid-1980’s and may be continuing on modern dairy farms (Lucy,...

Effect of Metabolic Stress on Ovarian Activity and Reproductive Performance of Dairy Cattle: A Review

Reproductive efficiency in dairy cattle has been decreased over the last 5 decades despite significant gains in genetic selection, improved reproductive technologies and nutritional care. In high-yielding dairy cattle, the negative energy balance (NEB) during the first week post-partum adversely affects ovarian activity, mainly follicle growth and steroidogenesis. Circulating levels of non-este...

Situations Leading to Oxidative Stress in Dairy Cattle

Free radicals are normally produced by living organism, at controlled production rate they perform physiological functions as signal transduction molecules. However, situations leading to an overproduction that surpasses antioxidant capacity creates oxidative stress. Consequently, damage to the cell membrane, protein, DNA and cell death are observed. Dairy cattle are susceptible to oxidative st...

Fall Conference 2015 – College of Veterinary Medicine at Urbana-Champaign Strategies to Improve Reproductive Performance in Cattle

Introduction The decline in fertility reported from 1960 to early 2000’s (Lucy, 2001) was the motive for prolific research in dairy cows, which in instance lead to identification of multiple culprit factors for this impaired reproductive performance in dairy cattle. (Norman et al., 2009; Santos et al., 2004). Reduced fertilization, embryonic survival, and high prevalence of anovulation in dairy...

Prevalence of immunoglobulin G (IgG) antibody to Neospora caninum in dairy cattle of Hamedan province, west of Iran

Bovine neosporosis caused by the apicomplexan protozoan parasite N. caninum, was initially recognized in 1989 and is now reported as a leading infectious cause of reproductive failure in dairy cattle in world wide. The aim of this study was to determine the seroprevalence of N. caninum infection in industrial dairy cattle of Hamedan province (west of Iran) by ELISA method. Blo...
