“…Macías et al [12] reported that in non-lactating ewes the differences in RT increase over the course of the d, being smaller in the morning and greater in the afternoon during the summer season. Similarly, in the study by Silva et al [26], significant effects of higher RT values were observed in the hottest h of the d which is consistent with the present values observed in both groups during the afternoon.…”

“…It is considered that due to the decrease in humidity in the CG the temperature is greater and that is enough for the ITH to increase in this group. It is known that according to environmental principles, these variables are inversely proportional [26]. However, the environmental conditions (EC) during afternoon resulted in an ITH which might be dangerous for ewes.…”

Physiological response to thermal stress in hair-sheep ewes during subtropical summer

et al. 2021

With the aim to assess the effect of short-term thermal stress on physiological traits of ewes an experiment was designed. Fourteen hair sheep ewes were selected during early reproductive management and randomly segregated in two groups. Control group (CG) with indoor conditions, and an experimental group (EG) under continuous outdoor conditions without shadow accessing during 14 days (d). Respiratory frequency (RF), rectal temperature (RT) and infrared image temperatures were estimated. Traits were measured for 8 d twice a d (9:00 am and 15:00 pm). Environmental temperature and humidity were monitored, and temperature and humidity index was estimated. All physiological and environmental traits showed significantly variation by group and time of measurement (P < 0.001). RT and RF were significantly higher for EG and during pm measurements. Environmental conditions indicated thermal stress conditions for outdoor EG during the afternoon was related ultimately with respiratory mechanism as the main indicator of continuous thermal stress. Head infrared image temperature was a good predictor of body temperature.

The objective of this study was to evaluate the inclusion of different levels of 0.0%; 0.7%; 1.4% and 2.1% of Noni (Morinda citrifolia) in the feeding of lambs regarding ingestive behavior and physiological variables. The experiment was carried out in a double Latin (4x4) experimental design with eight animals, consisting of four periods and four experimental rations. Eight lambs with no defined racial pattern were used, with mean initial body weight (BW) of 23.74 ± 1.00 kg. The ingestive behavior was performed during 24 hours, always on the last day of each experimental period. The physiological variables and the environmental variables were measured during three days of each period. Data were submitted for analysis of variance and, when significant, regression equation was applied at 5% of probability. Statistical analysis was performed considering the subdivision of the plot, which consisted of the diurnal and nocturnal evaluation times for the ingestive behavior and the morning and afternoon periods for the physiological variables. The inclusion of Noni in fed lambs did not change (p > 0.05) the time spent with ingestive behaviors for dry matter intake (DMI), rumination (RUM), idleness (IDL), water intake (WIN) and other activity (OAC). However, the daytime During the period there was gr eater (p < 0.05) time use for DMI, WIN and OAC. Inclusion of Noni to diets provided higher (p > 0.05) time use during the night time for RUM and IDL. The physiological variables were not influenced (p > 0.05) by the inclusion of Noni in the diets of lambs. However, higher mean (p < 0.05) body temperature of the front and rear, rectal temperature and respiratory rate of the lambs were observed during the afternoon. The inclusion of up to 2.1% of Noni in lamb feed does not alter ingestive behavior and physiological variables. However, the consumption of dry matter and water is higher during the diurnal period, while rumination and idleness are more active during the night period.
