Lambs were transported for 24 hours during summer and winter at a range of stocking densities. Shorn lambs of mean liveweight 39.5 kg were transported at densities of 0.448, 0.513, 0.602 and 0.769 m2/100 kg in July and fully-fleeced lambs of 37.3 kg mean liveweight were transported at densities of 0.613, 0.680, 0.775 and 0.909 m2/100 kg in February. Fewer lambs lay down and rested at high stocking densities and there was a marked increase in the plasma levels of creatine kinase at the highest stocking density in winter. All other measured effects of stocking density were small when compared with the overall effects of transport. There was a decrease in body temperature during transport, especially in the lambs that were recently shorn, even though they were transported during warm summer conditions. At the highest stocking density there was a smaller decrease in body temperature.
在夏季和冬季，将羔羊以一系列饲养密度运输24小时。平均体重39.5千克的剪毛羔羊在7月以0.448、0.513、0.602和0.769平方米/100千克的密度运输，平均体重37.3千克的全毛羔羊在2月以0.613、0.680、0.775和0.909平方米/100千克的密度运输。在高饲养密度下，躺下休息的羔羊较少，并且在冬季最高饲养密度下肌酸激酶的血浆水平显著升高。与运输的总体影响相比，饲养密度的所有其他测量影响都较小。运输过程中体温下降，尤其是最近剪毛的羔羊，即使它们是在温暖的夏季运输。在最高饲养密度下，体温下降幅度较小。
