Six experiments have been completed on day-old male cross-bred chicks for periods of up to 2 and 4 weeks to learn more about the role of pyridoxine in the etiology of gizzard erosion. At the end of each experiment, chicks were sacrificed and their gizzards removed and scored for the severity and incidence of erosion. The results of these experiments confirm the previous finding that the severity and incidence of gizzard erosion is increased by B6 deficiency. They further show that taurocholic acid, at 1% of the diet, had a protective effect against this erosion. Feeding B6-adequate rations to chicks that previously had been fed a B6-deficient diet led to partial healing of gizzard erosions. Results also indicate that the feeding of purified diets to growing chickens produces a higher incidence of erosion than that of practical-type diets. Texture of the diet did nt influence the incidence of the erosion, because grinding a practical diet to the same fineness as a purified diet did not increase gizzard erosion. Pair-feeding experiments showed that gizzard erosion in partially starved chicks was not a specific result of anorexia but of deficiencies in certain nutrients, one of which is vitamin B6.
已对一日龄雄性杂交雏鸡进行了六项实验，为期长达2周和4周，以进一步了解吡哆醇在肌胃糜烂病因学中的作用。每次实验结束时，将雏鸡处死，取出肌胃，并对糜烂的严重程度和发生率进行评分。这些实验结果证实了先前的发现，即维生素B6缺乏会增加肌胃糜烂的严重程度和发生率。实验还进一步表明，日粮中添加1%的牛磺胆酸对这种糜烂有保护作用。给先前喂食缺乏维生素B6日粮的雏鸡喂食维生素B6充足的日粮，可使肌胃糜烂部分愈合。结果还表明，给生长中的鸡喂食纯化日粮比喂食实用型日粮产生的糜烂发生率更高。日粮质地不影响糜烂发生率，因为将实用日粮研磨至与纯化日粮相同的细度并不会增加肌胃糜烂。配对饲喂实验表明，部分饥饿雏鸡的肌胃糜烂不是厌食的特定结果，而是某些营养素缺乏的结果，其中一种营养素是维生素B6。
