Influence of stocking density on weight and behavior of feedlot lambs
Leme, T.M.; Titto, E.A.L.; Neto, M.C.; Pereira, A.M.F.The aim of this study was to verify the influence of the animal density on the weight gain and behavior of confined lambs. 86 animals were confined after weaning in 23 pens of two lambs each (double pens) and four pens of ten animals each (collective pens). During the 80 days of confinement all lambs received the same diet and the animals were weighed at the beginning of the trial and every 14 days for the cont...

Vilela, R.A.; Leme, T.M.; Neto, P.F.; Balieiro, J.C.C.; Titto, E.A.L.; Pereira, A.M.F.Este estudo teve como objetivo avaliar a influência de recursos de climatização, ventilação e nebulização, sobre a fisiologia e o comportamento de vacas Holandesas alojadas em free-stall, durante o verão do sudeste brasileiro. Foram utilizadas 20 vacas Holandesas submetidas a dois tratamentos com e sem climatização. Os parâmetros ambientais registrados foram temperatura de bulbo seco, umidade relativa do ar e t...
Behavior of Holstein milking cows exposed to different environmental conditioni...
Vilela, R.A.; Titto, C.G.; Titto, E.A.L.; Pereira, A.M.F.; Pereira, A.C.A.P.M.; Leme, T.M.Objectives: The aim of the study was to evaluate the behavior of dairy cows in summer in relation to the environmental conditioning system (fans with or without misting). Materials and Methods: Twenty Holstein lactating cows were allotted in free-stall pens, divided in two groups: VN ? with fans plus misting; V ? only with fans. The behavior was estimated as time standing and eating, ruminating and idling activ...
Influence of season on plasmatic cortisol and IGF -I in dairy cows under therma...
Titto, E.A.L; Titto, C.G.; Negrão, J.A.; Canaes, S.T; Leme, T.M.; Vilela, R.A.; Geraldo, A.C.A.P.M.; Pereira, A.M.F.; Nogueira Filho, J.C.MObjectives: Access to evaporative cooling system can increase production in dairy cows due to improve thermal comfort. The aim of this study was to evaluate the impact of ambient temperature on thermoregulation, cortisol and IGF-I, and determine the efficiency of evaporative cooling system on the physiological responses in different weather patterns. Materials and Methods: 24 Holstein cows were housed in two gr...
INFLUENCE OF SHADOW AVAILABILITY ON SPERMATIC MORPHOLOGY OF BRAHMAN BULLS [Bos ...
Fantinato Neto, P.; Leme, T.M.C.; Amadeu, C.C.B.; Geraldo, A.C.A.P.M; Tribucci, A.M.O.; Colussi, A.M.; Pereira, A.M.F.; Titto, E.A.L.Under heat stress conditions, testicular degeneration can occur, even on zebu animals. Therefore, the aim of this work was to verify the occurrence of any possible effect of shadow availability on pasture on spermatic morphology of Brahman Bulls on Brazil Southeast. Five animals were allocated on pasture with shadow availability, and five bulls were allocated on pasture without any kind of shadow. No difference...

Vilela, R. A.; Fantinato Neto, P.; Pereira, Alfredo Manuel Franco; Leme, T. M. C.; Titto, C. G.Este estudo teve como objetivo avaliar a influência do recurso de ventilação sobre a fisiologia de vacas Holandesas alojadas em free-stall, durante o verão do sudeste brasileiro. Foram utilizadas 20 vacas Holandesas submetidas a dois tratamentos: controle e ventilação. Os parâmetros ambientais registrados foram temperatura e umidade relativa do ar e temperatura de globo negro. As variáveis fisiológicas avaliada...
Influence of pre-slaughter management on cortisol level in lambs
Titto, E.A.L.; Leme, T. M. C.; Titto, C. G.; Amadeu, C. C. B.; Fantinato Neto, P.; Vilela, R. A.; Pereira, A.M.F.This study aimed to verify the influence of the transport in open or closed compartments, followed by two resting periods (1 and 3 hours) for the slaughter process on the levels of cortisol as a indicative of stress level in lambs. The slaughterhouse was located 85 km away from the place of confinement and the transportation of the lambs was carried out in a cage truck type, each cage had a divider in the middl...
