Table 4.

Effect of castration and castration method upon feedlot arrival on testes weight in beef cattle

Item	Treatment*			SEM^†	P-value
Item	BAN	BUL	INJ	SEM^†	P-value
Testes weight, g^‡
Smallest testis	—	352	242	5.3	<0.01
Largest testis	—	376	313	6.4	<0.01
Total weight	—	727	550	12.0	<0.01

*BAN = bulls that received blood-restrictive rubber band placed upon the dorsal aspect of the scrotum, INJ = bulls that received 1 mL (100 mg Zn) of a Zn solution in each testis, BUL = bulls with testicles remaining intact.

^†Pooled standard error of the mean.

^‡Testes weight was determined by collecting testes from each BUL and INJ carcass after stunning and exsanguination at the commercial abattoir; testes were severed with a knife, placed in pre-labeled bags and immediately transported to the West Texas A&M University abattoir for weight determination using a digital scale. The testes were allocated into smallest and largest testis per animal prior to statistical analysis.
