Measuring individual free-choice protein supplement consumption by wintering beef cattle

Techniques to Reduce Free-Choice Liquid Supplement Consumption in Beef Cattle

Sales of liquid feed, excluding sales to feedlots, have grown by 50% during the 1990's and exceeded one million tons in 1998 (Anonymous, 1999). Many liquid feeds are offered free-choice to cattle grazing pasture, which has advantages of reduced labor costs, less feeder space per animal and feeder accessibility by more timid animals. With these advantages, the use of molasses based liquid supple...

Ruminal Protein Degradation in Beef Cattle

Five ruminally cannulated steers (initial BW = 375 ± 34 kg; ADG = 1.16 ± 0.13 kg) were used in a 5 x 5 Latin square design experiment to determine the effects of increasing urea level on intake, nutrient digestion, nitrogen balance and ruminal kinetics. Isocaloric (NEm = 2.11 Mcal/kg; NEg = 1.35 Mcal/kg) and isonitrogenous (2.24% N) steam-flaked corn-based diets with urea concentrations of 0.0,...

Methane and Protein from Beef Cattle Manure

Protein Requirements of Zebu Beef Cattle

Protein is one of the most important essential nutrients; it is involved in many vital functions in the body, such as growth and tissue repair, enzyme catalysis, transport and storage, coordinated movement, mechanical support, immunological protection, generation and transmission of nerve impulses, and control of metabolism, growth and cellular differentiation. Therefore, ensure adequate supply...

Choice of attractive conditions by beef cattle in a Y-maze just after release from restraint.

To provide useful information on how to moderate posthandling stress, the attractiveness of different conditions to beef cattle just after release from restraint was determined. Angus heifers were individually allowed to enter a choice area after 2 min of restraint in a squeeze chute and to choose between 2 pens. After the heifer had chosen a pen, it could freely access both test pens and the c...
