The complexity of livestock production systems implies the interrelation physical, technical, social, environmental, and animal factors. This study aimed (i) to classify characterize farms in representative typologies (ii) point out main factors responsible for differences between sheep farm Brazilian semiarid region. A structured questionnaire with 29 variables related livestock, technological, herd management, productive indicators was applied 65 farmers. typology classified,...
Studies on ruminant nutrition have been notable in recent years for the efficiency of results and providing useful information about maintaining or increasing maximum growth rate productive reproductive performance animals. The association several research lines can generate information. For ruminants, rumination process is a complex occurs stimulated by physical presence food, which basis any animal's diet, above all generates endogenous heat from ruminal movements metabolic processes that...
The objective was to characterize the adaptive profile and thermoregulatory responses of Saanen goats raised under tropical conditions. Twenty dairy were used. Its rectal temperature (RT, °C), respiratory rate (RR, breaths min−1), heart (HR, bpm) collected biweekly for two consecutive years. Individual blood samples determination thyroxine (T4; μg dL−1). All physiological higher in afternoon, except RR which morning. RT rainy season, HR T4 levels had no effect between periods year. RT, HR,...
In poultry farming, robots are considered by birds as intruder elements to their environment, because animals escape due movement. Their is measured using the distance (ED) technique. This study analyzes behavior of in relation ED through use a robot with two speeds: 12 rpm and 26 rpm. The objective understand whether speeds cause variations implications for animal stress. A broiler breeding cycle was analyzed (six weeks) introduction weekly. analyses were carried out on static images...
This study aimed to evaluate the influence of dietary supplementation organic selenium (Se) in non-lactating goats, as well possible changes physiological responses thermoregulation and blood constituents under semiarid conditions. The was undertaken for 42 consecutive days using 22 animals. Data were collected: (1) meteorological, (2) (3) haematological. respiratory rate, rectal temperature, epidermis temperature surface pelt presented decreasing values from day zero 42nd evaluation, with...
Context Animal husbandry in thermally stressful environments can be both complex and difficult, the anticipated effects of climate change are expected to increase this condition. Aim Thermoregulatory responses, acid–base electrolytic balance were evaluated indigenous ewes different coat colour during moments natural heat stress. Methods Fifteen (white, red black; five each) used data collected for six consecutive weeks dry rainy periods at three times day [(Moment 1) 0500 hours 0600 hours;...
