AIMS To investigate the effect of continuous feeding of antimicrobial growth promoters (tylosin or virginiamycin) on the swine faecal community. METHODS AND RESULTS The study consisted of two separate on-farm feeding trials. Swine were fed rations containing tylosin (44 or 88 mg kg(-1) of feed) or virginiamycin (11 or 22 mg kg(-1) of feed) continuously over the growing/finishing phases. The t...
Introduction Even though many of the cattle finished in the United States are fed in large feedlots there are still many small finishing operations that lack the equipment and facilities of commercial feedlots and there are individuals that have an interest in fattening their own beef; 4-H projects or locker beef are prime examples. When finishing cattle, the nutritional requirements do not var...
Two experiments were conducted at the Kansas State University Beef Cattle Research Center to determine the effects of feeding ground flaxseed (flax) during the receiving period on the growth, health, and subsequent finishing performance of heifers. Crossbred heifers (Exp. 1: n = 363, 214 +/- 1 kg of initial BW; Exp. 2: n = 377, 222 +/- 1 kg of initial BW) were purchased during January and April...
C ORN silage is being utilized in increased quantities in beef cattle growing and fattening rations. The research data of Hammes et al. (1964), with various ratios of corn to corn silage in fattening rations, have demonstrated that higher levels of corn silage can be justified because gains between high grain and high silage rations are similar, whereas, use of higher silage rations permits the...
The aim of the work was estimation of copper intake with the daily food rations used for alimentation of students of military high schools and soldiers doing compulsory military service in the Polish Army. An average planned copper content in daily food rations used for alimentation of students and soldiers amounted to 2.49±0.35 mg, and 2.44±0.25 mg respectively. The copper content in the daily...
An in vitro study was conducted to evaluate the optimum roughage to concentrate ratio in complete rations using unconventional sweet sorghum bagasse (SSB), a by product of ethanol industry as sole roughage source. Eight rations were prepared with roughage to concentrate ratio of 100:0 to 30:70. Significantly (P<0.01) higher in vitro gas production volume (ml) at 24 h incubation, in vitro organi...
Corn-finished cattle are the backbone of US beef production system. Traditionally fed a total-mixed ration (TMR) where all feed ingredients mixed together, delivered, and daily to cattle. Previous research evaluated complete self-fed finishing rations diet is placed into self-feeder. With advancements in technology varieties corn, purpose this study was determine differences gains, efficiency, ...
