The 270 Gushi white geese during growth period were divided into 9 groups, and each had 10 pullets with 3 replicates. 3×3 factorial arrangement was designed, consisting of 3 protein levels (12.4%-14.5%, 14.5%-15.5%, 15.5%-17.4%), 3 Ca levels (0.7%, 0.8%, 0.9%) and 3 P levels (0.30%-0.39%, 0.40%-0.41%, 0.50%-0.52%).

方法］将270只生长期固始白鹅随机分成9组，每组10只，各设3个重复，其饲粮采用蛋白水平为12.4%~14.5%、14.5%~15.5%、15.5%~17.4%，钙水平为0.7%、0.8%、0.9%，磷水平为0.30%~0.39%、0.40%~0.41%、0.50%~0.52%采用3因素3水平正交设计，比较每组日增重。

Selection for the early-maturing made chicken reach maturity early. To compare the growth parameter of L2 and S strains with similar body weight, it showed that selection for egg production might result in the dam lines pullets earlier to maturity indirectly.

比较体型相似的L2和S品系母鸡之生长性能参数，L2品系母鸡在性成熟速率方面略高於S品系母鸡，显示母系针对产蛋数进行选拔可能间接使初产提早。

In experiment 2, pullets previously maintained on a folate-devoid diet for 4 weeks, were used to compare the bioavailability of PGA with natural tetrahydrofolate from digested bacterial cell powder after a single forced feeding for 4 weeks repletion.

试验二：利用新母鸡四周的叶酸耗竭与四周的补满试验，比较合成的氧化型喋醯麸胺酸（pteroylglutamic acid； PGA）与经消化的细菌细胞粉末(digested bacterial cell powder； DBCP，含有天然的还原型四氢叶酸)，在新母鸡体内的吸收与代谢。

The purpose of this study was to investigate whether if the sex-linked dwarf gene can have similar effect as in the broiler breeder to improve reproductive performance in Red-feathered Taiwan Country Chicken and if it can be applied for commercial production. This experiment used L2 strain males of Taiwan Country Chicken carrying sex-linked dwarf gene to cross with females of Red-feathered Taiwan Country Chicken to produce normal and dwarf types of smaller pullets for this study.
