“…Such alterations of the constitution of bovine muscle would be relevant to its nutritive value, its performance in manufactured meat products and its palatability. Kulwich et al (1961) developed a method for estimating the composition of beef rounds based * Journal Paper no 3298 of the Purdue Agricultural Experiment Station.…”

SUMMARYThe effects of several dietary regimens on the fat-free mass and the dry-matter, ash and potassium-40 content of selected bovine muscles were estimated. Muscle data from 104 half-sib Angus steers were secured at several stages of growth and after several feeding regimens. The results indicated that a hay diet, by comparison to a higher energy silage diet in the early feeding period (216–340 kg live weight), suppressed the fat-free weight, reduced the dry-matter content and increased the ash content of several muscles. These effects of early diet were reversed, however, when the animals were subsequently fed higher-energy rations and slaughtered at heavier weights (409 and 454 kg live weight). Data on potassium-40 gamma emissions by composite muscle samples confirmed the existence of age- or weight-associated decreases and suggested possible dietary influences on potassium levels in bovine muscles. The trends in these data indicated that low dietary energy (hay feeding) in the early feeding period delayed the decline in muscle potassium that normally accompanies maturation.

“…Sixteen beef rounds were counted for a period of 42 to 51 minutes and the gamma ray emission data were related to their physical and chemical composition (Kulwich et al, 1961). The correlation coeffi-40 cient between pounds of separable lean and K count was 0.982 when adjustments were made for differences in efficiency due to differences in round weights (non-adjusted r = 0.975).…”
