Nutrition and Reproduction in Modern Dairy Cows
Genetic improvement programs have done a great job selecting animals with superior genetics for milk production. Selection with emphasis on milk production is generally recognized as the single most important objective of breeding programs in dairy cattle worldwide. As a result of this improvement, the dairy cow has changed significantly over the past 7 decades with a remarkable increase in mil...
متن کاملHierarchical Bayesian Methods to Model Heterogeneity in Cow- and Herd-level Relationships between Milk Production and Reproduction in Dairy Cows
Two of the most important broad classifications of phenotypes for successful dairy production are milk yield and fertility. The nature of the relationship between milk production and reproductive performance of dairy cows is uncertain due to conflicting results reported in many studies. A common deficiency in many such studies is an underappreciation of the dual dimension of the production-repr...
متن کاملInterrelationships of Heat Stress and Reproduction in Lactating Dairy Cows
Efficient reproductive performance of lactating dairy cattle in tropical/subtropical and arid environments throughout the world is impacted by a multiplicity of factors such as: the physical environment, socialeconomic status of producers, available nutrients, adaptability and genetic composition of cattle, intensive or extensive management systems, and available reproductive technology. Season...
متن کاملReproduction and Fertility Parameters of Dairy Cows Supplemented with Omega-3 Fatty Acid-rich Canola Oil
Dietary supplementation of lactating dairy cows with fat has long been used as a management tool to increase the energy density of feeds, improving milk production, reproduction and alleviating the menace of postpartum negative energy balance. In this paper, we show that while attempts have been made to investigate the effects of omega-3 (n-3) polyunsaturated fatty acid (PUFA) on reproduction a...
متن کاملPhysiological aspects of reproduction and fertility in dairy cows
Reproductive efficiency is an important aspect of dairy cattle production. To improve it in high yielding dairy cattle, a thorough understanding of the physiology of fertility and the reproductive physiological implications of the increasing metabolic demands associated with increasing production levels is essential. In this respect, the present paper focuses on the neuro-endocrine regulation o...
