Analyses were made of myoglobin content of rat skeletal and cardiac muscle following continuous exposure to simulated altitudes of 18,000 feet for a 2–10-week period. About five dozen rats were used. Acclimatization was associated with an increase in the myoglobin concentration of thigh, diaphragm, gastrocnemius and heart muscles. Total myoglobin content, however, increased during acclimatization in cardiac muscle but not in the three skeletal muscles. This finding together with the body weight changes and muscle weight changes suggested that the increases in myoglobin concentration of skeletal muscle may be merely a reflection of a decreased water content of muscles.

Stocking Rates

The influence of previous nutrition on both the intake of herbage and the body weight changes of grazing sheep was examined in two field experiments. In the first experiment, herbage intake and weight changes were compared at different stocking rates (three, six, and nine sheep per acre). The second experiment was designed to examine the influence of previous undernutrition on the digestive capacity of sheep and on their rate of consumption of herbage in the field. As compared with previously better-fed sheep under similar grazing conditions, the previously undernourished animals showed a capacity to compensate for their nutritional handicap at all stocking rates. Within a short time they reduced the body weight advantage held by their better-fed mates to a non-significant margin. Compensatory growth was associated with a significantly (up to 20%) greater herbage intake by the undernourished animals, but this higher feed intake did not cause an increase in wool production. Undernutrition did not influence the apparent digestibility of a diet, but was associated with an increased rate of herbage consumption under field conditions.

Reverse Situation

SummaryThis paper describes the effect of three different growth rates on some offal components of Angus cattle. The growth rates were: high (H, 0·8 kg/day), low (L, 0·4 kg/day) and high-maintenance (HM, 0·8 kg/day followed by a period during which body weight was held constant).Equations are presented which enable the weights of the offal components to be calculated within the body weight range 300–440 kg.For most tissues, weights in the H group were greater than in the L and HM groups and included: liver, rumen-reticulum, small intestine and the total alimentary tract. Weight of fat trimmed from the rumen-reticulum, omasum, large intestine and total alimentary tract was also greater in the H than in the L and HM groups. The reverse situation held for head, feet and tail and the spleen.In spite of these differences between groups in weights and composition of offals, the carcass composition in all groups was similar (Murray, Tulloh & Winter, 1974). It appears that, at a given body weight, changes in the offals may buffer the carcass against change in composition when cattle are exposed to different growth patterns.

Cattle Feeding

AbstractA 2-year study compared milk production and profitability for confinement feeding versus rotational grazing. Guernsey and Guernsey x Holstein cows grazed perennial grass pastures from mid-May to October or were fed in confinement. Averaged over both years, confined cows produced 7% more milk; their milk was similar in fat concentration to that of grazing cows. Body weight changes and health of the two groups were similar. Net return per cow averaged $64 higher for rotational grazing than for confinement because of lower costs for feeding, facilities, equipment, and labor. Intensive rotational grazing of pastures is a competitive alternative for dairy cow feeding. However, farmers in the northern U.S. will still require stored feeds from late fall through early spring.
