Performance and economic analyses of year-round forage systems for forage-fed beef production in the Gulf Coast.
On a global scale, most beef is produced from grazing pastures or rangelands. Certain limitations exist, however, such as not having adequate animal rates of gain for marbling and availability of adequate forage nutritional value and quantity for constant animal weight gains. In the last 20 yr, there has been an increased interest in forage-fed beef for multiple reasons (health related, environ...
متن کاملKnowledge and tools to enhance resilience of beef grazing systems for sustainable animal protein production.
Ruminant livestock provides meat and dairy products that sustain health and livelihood for much of the world's population. Grazing lands that support ruminant livestock provide numerous ecosystem services, including provision of food, water, and genetic resources; climate and water regulation; support of soil formation; nutrient cycling; and cultural services. In the U.S. southern Great Plains,...
متن کاملBreeding Systems for Beef Production
Pedigree. All individuals in a genetic population (such as a herd, family line, or breed) are related to some extent. One pedigree plan mates individuals more closely related than the average of the population; it is termed inbreeding. Long-term inbreeding in a closed herd may increase genetic uniformity, but inbreeding usually reduces performance, especially in fertility and survival. This is ...
متن کاملEvaluation of Grazing Alternate Summer and Fall Forages in Extensive Beef Cattle Production Systems
Studies across 5 yr involving 938 British-breed crossbred cattle (372 heifers, 566 steers) were used to evaluate the effects of grazing alternate summer and fall forages on slaughter breakeven cost of various beef production systems. Grazed summer forage combinations included 1) continuous brome, 2)brome and warm-season grasses, 3) brome and alfalfa or sudangrass, 4) brome and a monoculture of ...
متن کاملLevels of Supplementation for Grazing Beef Heifers
The objective of this experiment was to evaluate the effect of providing different levels of a supplement on the nutritional characteristics and productive performance of heifers on pasture during the rainy-dry transition and dry season in Brazil or tropical area. Thirty crossbred heifers with predominance of Zebu breed were used in a completely randomized experimental design. Treatments consis...
