A study assessed the poult plumage color of F1 progeny from artificially inseminated crossings between white and black indigenous turkeys. 72 hens (32 black, 40 white) and 10 toms were used (5 black and 5 white). The turkeys were grouped into four treatments based on the breeding plans: T1 (White toms × White hens), T2 (Black toms × Black hens), T3 (White toms × black hens), and T4 (Black toms × White hens). Semen was harvested from five white toms, pooled, and inseminated into hens in T1 and T3. Semen harvested from five black toms were also pooled and inseminated into hens in T2 and T4. All inseminations were carried out immediately after collection, and each hen received a dose of 0.02 mL. Insemination was done for 2 consecutive days in week 1 and once weekly; eggs were collected and incubated weekly for 12 weeks. Poult plumage colors were monitored and recorded weekly after the first 28 d. Average fertility in each of the treatments 1 (99.63%), 2 (99.81%), 3 (99.84%), and 4 (99.27%) were not significantly ( > 0.05) different among the treatments. Hatchability was highest in T2 (72.54%) and least in T1 (57.67%). Percentage white plumage poults in treatments 1, 2, 3, and 4 were 88.73%, 31.61%, 58.15%, and 54.63%, respectively. Percentage black plumage poults in T1, T2, T3, and T4 were 6.97%, 33.04%, 15.26%, and 23.76%, respectively, while 4.30%, 35.35%, 26.57%, and 21.61% were percentage checkered plumage poults in T1, T2, T3, and T4, respectively. There was no significant ( > 0.05) difference in the percentage checkered obtained in T2, T3, and T4; percentage of white poult in T3 and T4; percentage of black poult in T3 and T1. The major determinant of poult plumage color concerning quantity was the plumage color of breeder tom semen used for insemination.
一项研究评估了白、黑两种本地火鸡人工授精杂交所得F1代雏鸡的羽毛颜色。使用了72只母鸡（32只黑色、40只白色）和10只雄火鸡（5只黑色和5只白色）。根据育种计划将火鸡分为四种处理组：T1（白雄火鸡×白母鸡）、T2（黑雄火鸡×黑母鸡）、T3（白雄火鸡×黑母鸡）和T4（黑雄火鸡×白母鸡）。从5只白雄火鸡采集精液，混合后给T1组和T3组的母鸡输精。从5只黑雄火鸡采集的精液也混合后给T2组和T4组的母鸡输精。所有输精均在采集后立即进行，每只母鸡输精剂量为0.02 mL。第1周连续2天每天输精1次，之后每周输精1次；每周收集鸡蛋并孵化，持续12周。在最初的28天后每周监测并记录雏鸡的羽毛颜色。处理组1（99.63%）、2（99.81%）、3（99.84%）和4（99.27%）的平均受精率在各处理组间无显著差异（P>0.05）。孵化率在T2组最高（72.54%），在T1组最低（57.67%）。处理组1、2、3和4中白羽雏鸡的百分比分别为88.73%、31.61%、58.15%和54.63%。T1、T2、T3和T4组中黑羽雏鸡的百分比分别为6.97%、33.04%、15.26%和23.76%，而T1、T2、T3和T4组中花羽雏鸡的百分比分别为4.30%、35.35%、26.57%和21.61%。T2、T3和T4组中花羽雏鸡的百分比；T3和T4组中白羽雏鸡的百分比；T3和T1组中黑羽雏鸡的百分比均无显著差异（P>0.05）。就数量而言，雏鸡羽毛颜色的主要决定因素是用于输精的种雄火鸡精液的羽毛颜色。
