The objective of this study was to determine the critical points of the operation of broiler catching for transport to the processing plant from animal and operational perspectives. During catching, chickens, environmental variables (temperature and relative humidity) were constantly monitored to determine the Enthalpy Comfort Index (IEC). Also, the physiological variable rectal temperature (RT) was monitored as an indicator of stress suffered by the birds during this handling procedure. Bird welfare were evaluated by analyzing their behavior. The bag method was effective to prevent the struggling of birds while being taken from the broiler house to the transport truck, reducing physical injuries and losses during catching.

The incidence of prostatic malignancy has increased the use of tissue markers to detect cancer. Tissue specific antigens or differentiation antigens are found on the surface of normal cells. Clinically, these antigens are important to diagnose alterations in the tissues and for immunotherapy. The objective of the present study was to evaluate the prostatic acid phosphatase concentration in blood and seminal plasma of intact and healthy dogs at different ages. The evaluation was carried out by spectrophotometer, using a commercial kit. The prostatic acid phosphatase (PAP) levels did not differ according to the age and did not correlate with age or prostatic dimensions verified by ultrasonography. The PAP concentration values varied greatly within each group. However, more studies are necessary to evaluate the role of prostatic acid phosphatase in the canine prostate and its importance as a diagnostic test for prostate disorders.

La incidencia de cáncer de próstata ha incrementado el uso de los marcadores celulares para detectar el cáncer en este tejido. Antígenos específicos del tejido o antígenos de diferenciación se encuentran en la superficie de las células normales. Clínicamente, estos antígenos son importantes para el diagnóstico de alteraciones en estos tejidos y para la inmunoterapia. Este estudio trata de evaluar la importancia de la fosfatasa ácida prostática en la próstata canina e investigar su concentración en el suero y en el plasma seminal de perros saludables de diferentes edades. La concentración de fosfatasa ácida prostática en el plasma seminal y en el suero fue evaluada por espectrofotometría, utilizando un kit comercial. Los niveles de la fosfatasa ácida prostática (PAP) no fueron diferentes de acuerdo con la edad y no presentaron correlación con la edad o con las dimensiones de las próstatas verificadas por ecografía. Los valores de concentración de PAP presentaron una gran variación en cada grupo. Sin embargo, son necesarios más estudios para evaluar el papel de la fosfatasa ácida prostática en la próstata canina y su importancia como una prueba de diagnóstico para los trastornos de la próstata.
