Some 60 percent of Australia’s beef cattle are located in the subtropics and tropics with cattle grazing pastures which have seasonal peaks and declines in digestibility and total digestible nutrients (TDN).
Rumen additives used in the beef industry to prevent "off feed" conditions include buffers, neutralising agents, bentonites and rumen modifiers.
In high roughage diets, ruminal pH is relatively stable at 6.2-7.0. However, rumen acidity can quickly change depending on the rations composition and the level of feed management.
Acidosis and laminitis can be significant disorders of beef cattle fed high grain–low roughage diets or high grain–high acid roughages.
Lot feeding Brahmans has driven a profitable business shift for Central Queensland beef producers Peter and Ann Kirk and family.
Brahmans are worth their weight in gold, just ask Craig Forest, manager of Saxby Feedlot at Kilkivan.
Few people are better positioned to comment on progress in management efficiency and productivity improvement across the Australian feedlot industry than top US feedlot nutritionist, Gary Holcomb.
By-product feeds are generally available seasonally in large quantities, frequently vary in composition and often incur a high transport and storage cost.
Mineral concentrations in grazing situations vary considerably with forage species, and stage of growth. As a result mineral requirements of grazing beef cattle are often not met or are marginal.
Knowledge of the nutritional requirements of stock and the values of feeds are necessary for cost effective use of supplements.
Homemade silage has the potential to provide management flexibility and shorten the growing phase of the beef production pathway, according to Ken Rich, managing directory of Quality Silage Systems (QSS).
The properties and benefits of different types of processed grains have received increasing interest of nutritionists and beef producers.
The availability and price of stockfeeds is influenced by various domestic and international factors which impact on farm profits and the purchasing power of beef producers.
