维生素 C 为各种动物所必需的重要营养物质,一旦缺乏将会明显阻碍动物的生长和繁殖,降低动物机体的免疫力,使机体容易感染疾病,降低生长速度和饲料转换率。1.家禽家禽一般能自身经生化反应合成维生素 C,而且常规饲料中也有丰富的维生素 C,通常不会出现缺乏症。遇不利因素,如感染疾病、寄生虫侵袭或营养不良时,则有可能使家禽出现维生素 C 缺乏症。一般表现为生长速度下降,蛋产量和蛋壳质量降低,易患坏血病,体重下降,在高温下兴奋紧张。因此,在家禽出现上述应激情况时要适量补充维生素 C。2.猪成年猪体内一般能合成足够其需要的维生素 C,
Vitamin C is an important nutrient necessary for a variety of animals, once the lack of will significantly hinder the growth and reproduction of animals, reduce animal immunity, make the body susceptible to disease, reduce the growth rate and feed conversion rate. 1. Poultry Poultry generally biochemical reactions can be their own synthesis of vitamin C, and conventional feed is also rich in vitamin C, usually without deficiency. In the case of unfavorable factors, such as infectious diseases, parasitic infestation or malnutrition, there is a risk of vitamin C deficiency in poultry. The general performance of the decline in growth rate, reduced egg production and egg shell quality, susceptible to scurvy, weight loss, excitement at high temperatures. Therefore, in the case of poultry stress should be appropriate when vitamin C supplement. Pig adult pigs generally can synthesize the body enough vitamin C,
