Comparison of surgical castration at birth versus immunocastration on behavioural response and blood parameters (testosterone and cortisol) in Holstein fattening bulls
Descripción del Articulo
The behavioural response and blood parameters were compared in immunocastrated and surgically castrated bovine males. In total, 720 Holstein males, 7-8 months old and approximately 240 kg body weight were used. One group was immunocastrated by vaccination with Bopriva (commercial anti-GnRH vaccine)...

Comparison of surgical castration at birth versus immunocastration on behavioural response and blood parameters (testosterone and cortisol) in Holstein fattening bullsComparación de la castración quirúrgica al nacimiento versus inmunocastración sobre el comportamiento conductual y parámetros sanguíneos (testosterona y cortisol) en machos Holstein en engordaPérez Linares, CristinaCervantes Cazares, Jorge ArmandoFigueroa Saavedra, FernandoTamayo Sosa, Alma RossanaBarreras Serrano, AlbertoGarcía Reynoso, Issa CarolinaBolado Sarabia, José LeonardoRíos Rincón, Francisco GerardoGarcía Vega, Luis Antonioboprivacastrated bullshormonefatteningBoprivamachos castradoshormonasengordaThe behavioural response and blood parameters were compared in immunocastrated and surgically castrated bovine males. In total, 720 Holstein males, 7-8 months old and approximately 240 kg body weight were used. One group was immunocastrated by vaccination with Bopriva (commercial anti-GnRH vaccine) on days 1, 21, 101 and 181 days of the fattening and the other group was surgically castrated at birth. Blood samples were taken on vaccination days for testosterone determination and on days 181 and during slaughtering to analyse blood cortisol. Sexual behaviour (mounts and flehmen signs) and aggressive (threats and head butting) and social behaviour (sniffing, grooming, lowered head, and vocalization) were evaluated, finding no significant differences between treatments. Testosterone concentration in both treatments was below 1 ng/ml in all samples. Cortisol levels on day 181 of fattening were lower (p<0.05) with respect to the day of slaughtering in both treatments. Slaughter weight (242 days fattening) was 595.0 kg in immunocastrated males and 620.74 kg in surgically castrated males.Se comparó el comportamiento conductual y parámetros sanguíneos en toros inmunocastrados y quirúrgicamente castrados.

Un grupo fue inmunocastrado mediante vacunación con Bopriva (vacuna comercial anti-GnRH) los días 1, 21, 101 y 181 días de engorda y el otro grupo fue castrado quirúrgicamente al nacimiento. Se tomaron muestras de sangre los días de las vacunaciones para la determinación de testosterona y los días 181 y durante el desangrado en el sacrificio para analizar cortisol sanguíneo. Se evaluó el comportamiento sexual (montas y signos de flehmen), agresivo (amenazas y topetazos) y social (olfateos, acicalamiento, cabeza baja y vocalizaciones) no encontrándose diferencias significativas entre tratamientos. La concentración de testosterona en ambos tratamientos fue por debajo de 1 ng/ml en todos los muestreos.
