研究了维生素C(L抗坏血酸)对热应激产蛋鸡生产性能、血浆抗坏血酸、血糖和血清胆固醇水平的影响。150只72周龄第二产蛋周期的单冠白来航鸡在12周的整个试验期内被饲养在较高的环境温度(平均34.5C；28-42℃)中。A组(对照组)、B组和C组分别通过饮用水补充三种水平的维生素C，即0、1000或1200ppm。提高了蛋鸡的产蛋量、饲料转化率、蛋重和蛋重(P
Vitamin C (L-ascorbic acid) was evaluated for its effects on production performance, and plasma ascorbic acid, blood glucose and serum cholesterol levels in heat-stressed laying hens. One hundred and fifty, 72-week-old single comb white Leghorn hens in their second laying year cycle were kept at high ambient environmental temperature (average of 34.5 degrees C; range 28-42 degrees C) throughout the experimental period of 12 weeks. Three levels of vitamin C, 0, 1,000, or 1,200 ppm, were supplemented through drinking water to the treatment groups A (control), B and C, respectively. Hen-housed egg production, efficiency for feed conversion, egg weight and egg mass were improved (P
