Abstract: THE goat is used extensively as an experimental animal in ChemicaI Corps research. Some data are available on the physiological and biochemical characteristics of goats under normal environmental conditions (15° to 20° C.). Little is known, however, about the physiology and biochemistry of goats under adverse environmental conditions, particularly thermal stress. Further, the behavior of goats has not been charted in sufficient detail under any environmental condition. Knowledge of the behavioral, physiological, and biochemical responses in goats to temperature is basic to studies in which the reactions of goats to particular treatments are measured under other than "normal" environmental conditions.
Studies on the effect of various temperatures on the behavior and physiological reactions of the large (farm) animals have taken two forms. The earlier dealt with the effects of naturally occurring high temperatures in tropical or semi-tropical areas; the more recent work has been done in temperature-controlled laboratories. Techniques employed for the latter studies have been described by Brody (1948) and McDowell (1953). |

The objective of this work was to evaluate the effect of grazing intensity on the decomposition of cover crop pasture, dung, and soybean residues, as well as the C and N release rates from these residues in a long?term integrated soybean?beef cattle system under no?tillage. The experiment was initiated in 2001, with soybean cultivated in summer and black oat + Italian ryegrass in winter. The treatments consisted of four sward heights (10, 20, 30, and 40 cm), plus an ungrazed area, as the control. In 2009?2011, residues from pasture, dung, and soybean stems and leaves were placed in nylon?mesh litter bags and allowed to decompose for up to 258 days. With increasing grazing intensity, residual dry matter of the pasture decreased and that of dung increased. Pasture and dung lignin concentrations and C release rates were lower with moderate grazing intensity. C and N release rates from soybean residues are not affected by grazing intensity. The moderate grazing intensity produces higher quality residues, both for pasture and dung. Total C and N release is influenced by the greater residual dry matter produced when pastures were either lightly grazed or ungrazed. |
