The objective of this study was to assess the impact of cattle finishing diet and muscle type on meat quality. Consumer sensory response, proximate composition, Warner–Bratzler shear force (WBSF), fatty acid composition, and volatile compounds were assessed from the gluteus medius (GM) and triceps brachii (TB) muscles of cattle (n = 6 per diet) which were grain-finished (USUGrain) on conventional feedlot or 2 forage diets, a perennial legume, birdsfoot trefoil-fin-ished (USUBFT; Lotus corniculatus), and grass-finished (USUGrass; Bromus riparius). Diet had an interacting effect with muscle for all sensory attributes (P ≤ 0.002), except aroma and flavor (P ≥ 0.078). In …
Estimation Of The Trichomonad Concentration In Beef Bull Preputial Samples And Resultant Population Effect Of Pooling On Detection Of Tritrichomonas Foetus Using Qpcr, David J. Wilson, Thomas J. Baldwin, Amanda Wilhelm, Chelsea H. Whitehouse, Jennifer L. Bunnell, Kerry A. Rood, Arnaud Van Wettere

The primary objective was assessment of effect of sample pooling on Tritrichomonas foetus detection using qPCR in beef bulls within 5 logs of trichomonad concentration in spiked preputial samples. The secondary objective was to use qPCR Ct values to estimate the percentage of beef bulls in the field population within each log of trichomonad concentration. Solutions containing none, 1,10,100,1000 and 10,000 trichomonads (T)/ml were made and tested by qPCR. Test sensitivities for single positive samples were: 1 T/ml, 20/40 (50%); 10 T/ml, 40/40 (100%); 100 T/ml, 40/40 (100%); 1000 T/ml, 40/40 (100%); 10,000 T/ml, 40/40 (100%). For 5-sample pools (1 …
Selection And Development Of Replacement Beef Heifers, Norris J. Stenquist, James A. Bennett
Selection And Development Of Replacement Beef Heifers, Norris J. Stenquist, James A. Bennett
Archived Agriculture Publications
Selection, development, management, and nutrition of heifer calves to be used as herd replacements are key factors in maintaining beef herd productivity. A cow/calf producer, to be successful, must have some goals or criterion for heifer selection and development. For practically all Utah cattle production areas, economics dictate that heifers must calve as two-year-olds. Heifers must be properly developed and managed to permit this. The following factors are important: Heifers should 1) become pregnant in the first 25 days of the breeding season, 2) give birth to a live calf with little or no calving difficulty, 3) raise a calf …
Growth Stimulants And Feed Additives, Norris J. Stenquist
Growth Stimulants And Feed Additives, Norris J. Stenquist
All Archived Publications
In recent years, the most revolutionary increases in beef cattle weights and feeding efficiencies have resulted from the development and use of growth stimulants, feed additives, and antibiotics. These nonnutritive products not only improve the rate and efficiency of gain but prevent certain diseases as well. Their use has significantly improved beef cattle production efficiency and provided a greater return per dollar invested than any other factor in the livestock industry. Growth stimulants deposit increased protein in the animal without changing protein or energy intake. They are designed to provide a constant slow release of active ingredients into the animal's …
Selecting For Carcass Merit, Norris J. Stenquist
Selecting For Carcass Merit, Norris J. Stenquist
Archived Agriculture Publications
Today's consumers are asking for leaner, less-fatty beef. Much of the leaner beef now produced results from trimming excess fat before the product is sent to the consumer. For the future, the hope is to trim excess fat genetically by producing leaner, more heavily muscled beef cattle.
