Economic evaluation of crossbreeding for dairy production in a pasture based production system in Kenya
Data on accumulated life performance of crosses of Ayrshire (A), Brown Swiss (B), Friesian (F) and Sahiwal (S) cattle collected over a 21-year period from a dairy ranch in the lowland tropics of Kenya were analysed to estimate additive and non-additive genetic effects on economic traits. These were used to predict and compare, first, performance of cows under nine crossbreeding strategies and, ...
متن کاملNutritional limitations to increased production on pasture-based systems.
The constraints to high levels of milk production imposed by a high-quality-pasture diet, and development of feeding strategies to overcome these limitations, were examined by modelling the nutritional status of New Zealand Friesian and North American Holstein-Friesian dairy cows grazing high-quality pasture. The Cornell Net Carbohydrate and Protein System (CNCPS) was used to predict sensitivit...
متن کاملInvited review: Genetic considerations for various pasture-based dairy systems.
Pasture-based dairy systems use grazing to supply significant percentages of the dry matter intake of cows and heifers. Such systems vary from those for which pasture is used only as a supplemental feed for cows primarily fed a total mixed ration to those for which pasture is the primary source of dry matter for the herd. Cows that are optimal in a pasture system share many general characterist...
متن کاملPasture intake and milk production of dairy cows rotationally grazing on multi-species swards.
Increasing plant species diversity has been proposed as a means for enhancing annual pasture productivity and decreasing seasonal variability of pasture production facing more frequent drought scenarios due to climate change. Few studies have examined how botanical complexity of sown swards affects cow performance. A 2-year experiment was conducted to determine how sward botanical complexity, f...
متن کاملIncreased production reduces the dairy industry’s environmental impact*
All food production systems have an impact upon the environment, regardless of how and where the food is produced. The effects that agricultural practices have upon environmental parameters are increasingly well-known, not only to the global and national industries, but also to policy-makers and consumers. Increased public awareness of these issues underlines the critical need to adopt dairy pr...
