Abstract

The essay was developed at the Estação Experimental de Zootecnia de São José do Rio Preto, State of São Paulo, Brazil, using 51 crossbreed Santa Gertrudis young bulls raised in grazing regime, in "pangola"-grass, "estrela"-grass, "batatais"-grass and "jaraguá"-grass paddocks. The animals were born in the second bimester of 1978 and 1979, and were arranged in a complete randomized design with three treatments and 8 and 9 replications in the first and second years, respectively. The treatments: CC = surgical castration, CQ = chemical castration and NC = checks. The animals of the chemical treatment received one intra-testicular shot of a 40% formic aldehyde solution plus additives and had fever only in the day after the shot day. The surgical treatment animals had fever form the second until the eightieth day after the surgery. It was not statistical difference between treatments for live weight gains but the difference between years was statistical significant. It was concluded that the chemical castration in cattle would be advised when the animals are to be slaughtered elder. Besides the simplicity, the chemical castration is less demaged and presents less jot surgery problems.
