A total of 18 cattle (between 60 ~ 72 weeks of age) comprising three genotypes (white Fulani, N'dama and white Fulani x N'dama) were used for the experiment. Growth traits measured in centimeters were body length (BDL). hip height (HHT), heart girth (HG). horn length (HL). tail length (TL), ear length (EL) and neck length (NL). The regression analysis was simple linear regression. The values of coefficient of determination (R') ranged from 50.00 to 94.20 in White Fulani (WF), with BL and HG having the highest R2 This implies that BL and HG could be the best predictors Of growth in WF. The values of R2 ranged from 36.00 to 66.00% in N'dama (ND) cattle with HHT having the highest R2 (66.00%). R2 ranged from 80.00 to 90.00% White Fulani x N'dama genotype with TL having the highest R2 value of90.00%. This implies that TL could be the best predictors of growth in WF x ND genotype. Amongst all, BL and HG of White Fulani genotype had highest R2 value (94.20%). Thus BL and HG could be best trait with 94.20% accuracy ofprediction, and may be useful criterion in prediction of growth.

机译：实验总共有18个牛（在60〜72周龄之间），其中包括三种基因型（白色Fulani，N'dama和White Fulani X N'Dama）。以厘米为单位测得的生长特征为身体长度（BDL）。髋关节高度（HHT），心脏腰围（HG）。喇叭长（HL）。尾部长度（TL），耳长（EL）和颈部长度（NL）。回归分析是简单的线性回归。在白色Fulani（WF）中，确定系数（R'）的值范围为50.00至94.20，而BL和HG具有最高的R2，这意味着BL和HG可能是WF增长的最佳预测指标。 N'Dama（ND）牛的R2值范围为36.00至66.00％，HHT的R2为最高（66.00％）。 R2的范围从80.00至90.00％的白色Fulani X N'Dama基因型，TL的R2值最高为90.00％。这意味着TL可能是WF X ND基因型增长的最佳预测指标。在所有人中，白色Fulani基因型的BL和HG具有最高的R2值（94.20％）。因此，BL和HG可能是预测精度为94.20％的最佳性状，并且可能是预测生长的有用标准。
