feedlot, beef, supplement
The impact of liquid, meal, and pelleted supplements on feedlot performance and liver abscesses was evaluated in yearling steers. Steers were fed 90% concentrate diets and test supplement sources for 105 days. The control diet included all supplemental feed ingredients in pelleted form. Four other diets included a liquid supplement that contained supplemental vitamins, minerals, and monensin and a dry supplement providing protein and tylosin all equal to the control. The protein-tylosin component was fed in meal or pelleted form. Overall, steers fed liquid supplements outperformed steers fed dry pelleted supplements with higher average daily gain (P=.05) and dry matter intake (P<.05). Interim average daily gain was greater when liquid supplements were fed only through the initial 56 days of the feeding period. Dry matter intake responses occurred in three of the four interim periods. No benefit was noted for pelleting the protein-tylosin mix, except during the initial 28 days. Liver abscesses were higher (1 7.5% vs 8.8%, P=.10) when diets contained no liquid supplement. Results indicate that including liquid supplements may increase uniformity of nutrient and feed additive consumption and thereby enhance cattle performance.
