Abstract: At a mean age of 93 +/- 5 days and a mean weight of 29 +/- 5 kg, 44 crossbred ram lambs were castrated to evaluate the accuracy of the estimation of testis weight from in situ testis measures (scrotal circumference and testis diameter). Means and standard deviations for testis weight (both testes), scrotal circumference and average in situ testis diameter were 134 +/- 57 g, 20.2 +/- 3.1 cm and 3.7 +/- .7 cm, respectively. Testis weight (W) was predicted from scrotal circumference (C) and average in situ diameter (D(o)) as W=.131C(1.90) D(o)(.88) (R(2)=.949). When adjusted to the same scrotal circumference and in situ diameter, testes of 3/4-Finnish Landrace rams were heavier (P<.05) than testes of 7/8-Dorset rams. However, the additional accuracy obtained by using equations specific to each crossbred group was small. |
