饮食中的吉泽罗辛和组胺能刺激胃液分泌。如果适度刺激胃酸分泌，饲料中的钙可能会在十二指肠和空肠上端溶解和吸收，从而加速雏鸡股骨的钙化。为了证实这一可能性，进行了三个试验。为了减少遗传维生素D_3的影响，使雏鸡对维生素D_3敏感，饲喂不含维生素D_3的日粮。试验一，在日粮中添加或不添加维生素D_3 50μg/kg，连续饲喂10天。在试验2中，比较了添加200ppm组胺和2ppm组胺对雏鸡股骨灰分和钙含量的影响。先饲喂不含VD3的基础日粮19天，然后饲喂试验性日粮7天。正在节食吉泽罗辛。与对照组相比，组胺饲料中的钙含量增加，但组胺日粮中的钙含量没有增加。在试验3中，为了再次确认组胺对股骨中灰分和钙的含量没有影响，饲喂含组胺2000ppm的日粮14天。结果表明，日粮中添加维生素D3可显著提高肉仔鸡股骨灰分和钙含量，但对组胺含量无显著影响。
Dietary gizzerosine and histamine stimulate the gastric secretion. If they moderately stimulate the gastric acid secretion, the dietary Ca may be solubilized and absorbed in the duodenum and the upper jejunum resulting in acceleration of calcification in the femur of young chicks. In order to certify this possibility, three experiments were conducted.In order to diminish the effect of inherited VD3 and make chicks susceptible gizzeosine, VD3-free diet was supplied.In experiment 1, to confirm the effect of gizzerosine, the chicks were fed the diets containing 2ppm of gizzerosine with or without 50μg of VD3/kg for 10 days. Contents of ash and Ca in the femur of chicks increased significantly only when gizzerosine was added to diets with VD3.In experiment 2, the effect of 200 ppm dietary histamine was compared with that of 2 ppm of gizzerosine. Chicks were fed the VD3-free basal diet for 19 days and then experimental diets for 7 days. On the gizzerosine diet. the Ca content in the femur increased, but not in the histamine diet compared to the control diet.In experiment 3, to reconfirm no effect of histamine on the contents of ash and Ca in the femur, chicks were fed the diet containing 2000 ppm of histamine for 14 days. The content of ash and Ca in the femur of chicks decreased.These results showed that supplementation of dietary gizzerosine with VD3 caused significant increase of ash and Ca contents in the femur, but no significant effect was observed on the dietary histamine.
