Symposium on Pasture Methods for Maximum Production in Beef Cattle: Finishing Steers on Pasture in Northeastern Saskatchewan

Compudose 200 (Elanco) is a silastic rubber ear implant for beef cattle containing 24 mg oestradiol 17B, Implants are 3 cms long and 4.8 mm in diameter. They are coated with oxytetracycline powder as a local antibacterial and packed in cartridges of 10. The cartridge is fitted to the side of the implanting tool and each Implant is moved into the barrel of the implanter by a “thumb press” on the cartridge. The objectives of the present study were (i) to measure the growth response to Compudose 200 in male calves, growing steers at pasture and housed finishing steers, (ii) to ascertain if there was an additive effect from the use of 300 mg trenbolone acetate (Flnaplix, Hoechst) with Compudose 200 in growing and finishing steers and (iii) to compare Compudose 200, alone or in combination with Finaplix, with other commonly used implant combinations.

Finishing Steers

Trials were conducted to determine the effectiveness of adding elevated levels of NaCl and limestone to the diet of fattening beef steers as a means of improving feedlot performance. In Trial 1, 24 Hereford steers were fed high grain diets containing 0.5% (control), 3%, 5%, or 7% NaCl for 126 days. Growth and feed efficiency were not affected by level of NaCl, although feed intakes, organic matter intakes and carcass weights were reduced at the 7% level as compared with the control. Acetate to propionate ratio increased from 1.9 to 2.8 (P < 0.05) with NaCl supplementation while fecal starch tended to increase from 10.3% to 18.7% (P < 0.12). In Trial 2, 24 steers were fed finishing diets containing 0.5% NaCl (control), 2% limestone, 5% NaCl or 5% NaCl plus 2% limestone for 119 days. Steers consuming 5% NaCl or 5% NaCl plus 2% limestone showed 7.4% and 8.9% increases (P < 0.05) in efficiency of organic matter utilization over those fed the control diet. Addition of limestone to the 5% NaCl diet did not markedly increase performance over that seen with NaCl supplementation alone. Similar to Trail 1, fecal starch concentrations tended to increase (P < 0.10) in diets containing NaCl regardless of limestone supplementation. Use of 5% NaCl in the diet of finishing steers may be useful in increasing feed efficiency. Key words: Beef cattle, sodium chloride, high grain

Finishing Beef Cattle

Barley silage (mid-dough), mature, dry-ground, whole-plant barley, and corn silage were evaluated for growing and finishing steers over two consecutive crop years. Adequate supplemental protein was provided. Steers fed barley silage gained the least and required the most feed dry matter per unit gain. Furthermore, barley silage produced the least fat cover and lowest dressing percent. Performance of steers fed dry-ground barley was intermediate during the first year, but comparable with performance on corn silage in gain and carcass measurements during the second trial. Digestible energy intake tended to be highest for steers fed corn silage. Sheep were used to determine digestibilities of forages fed in the feedlot studies, and of whole-plant barley at various stages of maturity. Corn silage had the highest energy digestibility of all forages studied. Energy digestibility of whole-plant barley decreased slightly to the milk stage but did not change thereafter. After the milk stage, the barley had a moisture content below 70%, thus enabling direct harvesting for silage.
