Abstract:
Pre-slaughter fasting duration affect blood parameters related to stress and metabolism, decrease live and carcass weights and impact beef quality of cattle. In three experiments, 1100 steers and heifers, finished on feedlot or on pasture, were evaluated to assess the influence of the site and duration of fasting before slaughter on physiological, carcass and meat quality traits. Cattle were allocated to one of two fasting duration - long (23?29 h) or short (2?6 h) ? and to one of two sites of fasting? farm or abattoir. All animals had access to water ad libitum until slaughter, except during transportation. Cattle were assigned to two (long fasting on abattoir/normal lairage time, short fasting on farm/minimal lairage time) or three (long fasting on abattoir/normal lairage time, short fasting on farm/minimal lairage time, long fasting on farm/minimal lairage time) treatments. Seventeen slaughters were considered in a randomized complete block design. There was no effect of the site of fasting on any variable. Cattle with short fasting duration had higher carcass weights and water consumption than those under long fasting duration. Haematocrit, globulin, total protein, and lactate dehydrogenase at the time of slaughter increased with fasting duration. There was no effect of the duration of fasting on blood ions, meat quality traits, urine pH, liver weight and volume, and skin dry matter. A reduction in the fasting duration returned to farmers and abattoirs 1.2% additional kilograms of carcass, suggesting an improvement in animal welfare according to a better hydration level of cattle at the time of slaughter.

Resumen:
El objetivo de este estudio de laboratorio fue evaluar el efecto del fotoperiodo y la temperatura en: la morfometría, el color del cuerpo, contenido de lípidos, desarrollo de los órganos reproductivos y la actividad alimentaria de Piezodorus guildinii (Westwood). Fueron evaluadas tres condiciones diferentes (14:10 y 10:14 h L:O a 25 °C, y 10:14 h L:O a 20 °C), a 80 ± 10% HR. Los adultos en 14 h de fotofase (25 °C), fueron más grandes y tuvieron menor
contenido de lipidos que en 10 h (20 °C). La mayor proporción de hembras con banda del pronoto y conectivo claro fue registrada en 10 h de fotofase (20 y 25 °C). La condición del ovario fue afectada por el fotoperiodo y la temperatura. A los 15, 30 y 45 días de edad, en 14 h de fotofase (25 °C), 0% de las hembras exhibió el ovario inmaduro; por el contrario en 10 h (20 °C), durante ese período el porcentaje de hembras con ovario inmaduro disminuyó de 60
a 33%. El fotoperiodo y la temperatura afectaron el tamaño de los testículos; siendo mayor y menor a 14 h (25 °C) y a 10 h (20 °C), respectivamente. La condición del saco ectodérmico fue afectada a partir de los 15 días de edad; la proporción de machos con saco ectodérmico expandido fue mayor a 14 h (25 °C) que a 10 h (20 °C). La actividad alimentaria de los adultos disminuyó en condiciones de fotofase corta (10 h). Los resultados obtenidos indican que
los adultos de P. guildinii en condiciones de 10 h de fotofase y 20 °C ingresan en diapausa reproductiva, acumulan reservas energéticas (lípidos), tienen estructuras reproductivas inmaduras, cuerpo más pequeño, banda del pronoto y conectivo de coloración clara, y actividad alimentaria menor.
Abstract: The effect of photoperiod and temperature on Piezodorus guildinii (Westwood) adult body morphometry, color, lipid content, development of reproductive organs, and feeding activity at different ages was studied in the laboratory. Three different conditions were tested, each at 80 ± 10% RH: 14:10 h L:D at 25 °C, 10:14 h L:D at 25 °C, and 10:14 h L:D at 20 °C. Adults at 25 °C under 14 h photophase were larger and exhibited lower lipid content than those held at 20 °C under 10 h photophase. Highest percentages of females with clear pronotum band and connexivum were recorded at 10 h photophase regardless of the temperature. Development of the ovary was affected by both photoperiod and temperature. At 15, 30 and 45 days of age under 14 h photophase at 25 °C, the percentage of females with immature ovaries remained constant at 0%; in contrast, at 10 h (20 °C) this percentage declined from 60 to 33%. Testes size was affected by photoperiod and temperature; males at 14 h (25 °C) and at 10 h (20 °C) showed the largest and the smallest testes, respectively. The ectodermal
sac condition was affected starting with males 15 days of age; the percentage of males with an expanded ectodermal sac was greater under the 14 h (25 °C) treatment than under the 10 h (20 °C) treatment. Feeding activity of adults under short photophase conditions (10 h) decreased. These laboratory results indicate that adults of P. guildinii maintained under a short (10 h) photophase at 20 °C enter into reproductive diapause, accumulate energetic reserves (lipids), show undeveloped reproductive structures and smaller size, clear coloration of the pronotum band and connexivum, and less feeding activity.
