Effects of Ractopamine (Optaflexx) Fed in Combination with Melengestrol Acetate on Feedlot Heifer Performance
Two commercial feedlot experiments were conducted to determine the effects of feeding melengestrol acetate (MGA) or MGA plus ractopamine (MGA+OPT) on the performance and carcass characteristics of finishing heifers. In Nebraska (Exp. 1), 1,807 heifers (337.3 ± 20.0 kg) and in Texas (Exp. 2), 1,964 heifers (331.5 ± 6.1 kg) were fed 0.4 mg of MGA daily. For heifers fed MGA+OPT, 200 mg of ractopam...
متن کاملSalinomycin Levels For Feedlot Steers and Heifers
A new feed additive, salinomycin, was fed to 70 finishing steers (initial weight of 772lb) and 70 finishing heifers (initial weight of 4951b) for 139 and 145 days, respectively. Salinomycin was fed at 0, 5, 10, 15, and 20 g per ton of a ground corn based diet. Averaged across salinomycin levels, gain was increased 2.6 percent and efficiency of feed use was improved by 7.8 percent. Feed intake w...
متن کاملHeat stress risk factors of feedlot heifers
Heat stress in cattle results in millions of dollars in lost revenue each year due to production losses, and in extreme cases, death. Death losses are more likely to result from animals vulnerable to heat stress. A study was conducted to determine risk factors for heat stress in feedlot heifers. Over two consecutive summers, a total of 256 feedlot heifers (32/ breed/ year) of four breeds were o...
متن کاملZinc Sulfate
Zinc sulfate is an inorganic compound: the sulfate salt of zinc and a good source of zinc ions. The molecular 40 formula for zinc sulfate is ZnSO4. A graphic representation of the structure of zinc sulfate is shown in figure 1 41 (Pubchem, 2014). Zinc sulfate appears geologically as a white crumbly salt efflorescence known as “goslarite.” 42 Goslarite, the heptahydrate of zinc sulfate was first...
متن کاملComparison of heat tolerance of feedlot heifers of different breeds
Heat stress in cattle causes decreases in feed intake and feed efficiency; in extreme cases, it can cause death. These losses amount to millions of dollars each year. A study was designed to determine severity of heat stress among four breeds of cattle. Throughout two summers, 256 feedlot heifers of four different breeds were observed. Respiration rates, panting scores, and surface temperatures...
