“…Animal behavior can be used to indicate quality of the whole production system, including individual activities of the animal in its social and physical environment (Custodio et al, 2017). There is increasing concern about animal welfare and economically viable productive management (Eustáquio Filho et al, 2014).…”

Ingestive behavior and efficacy of male sheep housed in different stocking densities

et al. 2019

The objective of this study was to analyze the effect of housing density on ingestive behavior of male Santa Inês sheep housed individually and in double. Forty non-castrated males were used with an average initial weight of 21.33±2.62 kg and an average age of 120 days. The males were housed in two types of covered stalls: double stalls (two males/stall) of 3.0 m 2 and individual stalls of 1.50 m 2. Animals housed in individual stalls spent more time ruminating and less time eating than those in double stalls. These animals also spent more time in idleness. Sheep idled approximately 11.43 hours/day (47% of the time), which can be explained by the shorter time spent in rumination, considering that the diet used in this experiment had adequate nutritional quality. The animals in double stalls consumed more water, which resulted in increased urination. However, this activity did not interfere with total weight gain. Therefore, experiments testing stall density does not interfere with the performance of the animals.

“…The quantity of feed intake may vary by 40% to 60%, depending on factors inherent in individual animals, by 20% to 30%, depending on the characteristics of feed on offer, and by 10% to 15%, depending on environment and management (Van Soest, 1994). This confirms that management can affect feeding behaviour, which will result in altered animal performance, and the economic viability of the production system (Eustáquio Filho et al, 2014;Custodio et al, 2016).…”

The objective of this research was to evaluate lamb diets with a high proportion of concentrate and various levels of physically effective neutral detergent fibre (NDF) using tropical ingredients. Four diets were formulated: D1 with 16.5% physically effective NDF (peNDF), D2 with 21.4% peNDF, D3 with 23.3% peNDF, and D4 with 24.6% peNDF. Twenty male Santa Inês lambs at four months old with an average liveweight (LW) of 18.6 ± 3.4 kg were fed for 49 days. There were no differences (P >0.05) among the diets in dry matter (DM) intake. Crude protein (CP) intake, relative to either LW or metabolic live weight (LW0.75) or LW, was greater (P ≤0.05) for D2 and D3 than for D1 or D4. Lower (P ≤0.05) NDF intake, relative to LW0.75 or LW, was lower for D1 than for the other diets. Selection indexes (SIs) were similar (P >0.05) among diets. Animals that consumed D1 had less (P ≤0.05) rumination time per bolus. Meaningful variations were not observed in performance and efficiency of finishing lambs that were related to differences in peNDF among the diets. Santa Inês lambs were able to adapt to diets with low levels of peNDF by increasing rumination time as a consequence of increased fibre consumption and greater particle size selection.

“…Behaviors exhibited by animals serve as indicators of the quality of the production system. These behaviors encompass individual activities of animals and are influenced by environmental factors, such as air temperature, humidity or water quality (Custodio et al 2017). Animal performance may depend on behavior activities, diets, breeding as mentioned by Costa et al (2019) and Furtado et al (2021).…”

This experiment aimed to determine the effect of adaptive duration to saline water on behaviors, weight gain and blood biochemical parameters in growing goats. The experiment was arranged in a completely randomized design, which included four treatments with five animals per group. The goats were administered either fresh water (control) or seawater with a salinity of 1.5%, with varying durations of adaptation to seawater. The adaptive durations included an abrupt change (A0) from fresh water to seawater with a salinity of 1.5% or stepwise adaptation either 4 (A4) or 7 (A7) days of increasing saline concentrations. The results showed that dry matter intake in the non-adapted goats (A0 group) was lower than that of the control group or the adapted goats throughout the experiment (p<0.05). In contrast, water intake from drinking saline water was greater than that in the control group (p<0.05). Body weigh did not differ among the treatments; however, non-adapted goats exhibited a lower weight gain than the adapted goats (p<0.05). The goats in the A0 and A4 groups exhibited increased plasma levels of urea, AST, and ALT compared with the control and A7 groups. However, blood electrolyte levels remained unchanged and were within the normal range for goats. Therefore, it is concluded that the stepwise adaptation to seawater with a salinity of 1.5% for 21 days has no influence on productivity and health status of goats.
