“…In accordance with our observations; researchers also reported reduced rumination in ruminants under heat stress (Hirayama et al, 2004;Moallem et al, 2010). Rumination generally generates heat through bacterial fermentation (Piccione et al, 2014) and it is a good indicator of animal welfare (Gregorini et al, 2012).…”

Extended hot summer is a major constrain in animal production in the semi-arid tropical region. However, the adult native sheep is well-adapted to this climatic condition. Nonetheless, the adaptability of growing lambs in summer conditions is yet to be explored for sustainable sheep production. Therefore, the present study was carried out to assess the effect of summer environment on the growing lambs under hot semi-arid region. For this purpose, sixteen Malpura weaner lambs of 3-4 months of age were selected and equally distributed into two groups, viz. C and T. The lambs of T groups were kept inside the psychometric chamber in different temperature and humidity schedules simulated with the summer average temperature and humidity of the last 10-year of the semi-arid tropics. The lambs of C groups were kept inside the pen in a thermocomfort environment with the same space availability of T group lambs. The lambs of both the groups were provided with adlibitum feed and water. The water intake, respiration rate (RR), pulse rate (PR), rectal temperature (RT) and skin temperature of T group lamb was significantly (P<0.05) higher as compared to C group lambs. The summer exposure (T) reduced (P<0.01) the feeding and rumination time whereas increased (P<0.01) the panting in lambs as compared to C group. The endocrine profile did not varied (P>0.05) with the simulated summer exposure of semi-arid region in lambs. The present study reflected that the native Malpura growing lamb modifies their behavior and thermoregulatory responses to counter the extreme summer of the semi-arid region.

“…They stimulate the sympathetic pathway of the autonomic nervous system and may alter the thermoregulatory set point (Pedernera‐Romano et al., ), which can be a potential welfare indicator (Ingram et al., ). Rectal temperature has traditionally been used to measure the core temperature of animals, although miniature temperature data loggers have recently been employed to measure core temperature, while avoiding the potential stress of rectal measurement (which itself could induce a rise in body temperature; Piccione et al., ).…”

SummaryThe study was conducted to evaluate the thermophysiological, haematological, biochemical and behavioural stress responses of sheep transported on road. A total of 44 Chamarita breed adult ewes were randomly allotted to one of two groups, one control group (untransported) and transported group (journey of 4 h), and blood stress indicators were measured 1 day before transport and at four time points post-transport (0, 4 and 24 h). Thermophysiological profiles of ewes were measured by temperature buttons (iButton Thermochron â ) and placed in intravaginal sponges. Direct observations, with a combination of scan and behaviour sampling, were carried out to collect information on individual behaviour and the time it took the ewes to drink water, eat and rest after returning to their pen respectively. Transported ewes lost approximately 1 kg live weight compared to controls and had higher body temperatures until 12 h post-transport. Cortisol, glucose, non-esterified fatty acid (NEFA) concentrations as well as the neutrophil-lymphocyte ratio (N/L) and other physiological indicators were higher immediately after unloading in transported ewes but mostly returned to normal after 4 h, with complete recovery after 24 h. Behavioural analysis post-transport demonstrated that transported ewes chose to eat before drinking and spent less time resting than controls in the first 3 h after unloading. The study demonstrates that transportation even under short-journey conditions induced behavioural, physiological and thermophysiological responses indicative of the induction of significant stress, leading to live weight shrinkage that may jeopardize farmer's incomes. Finally, results of this study validated the use of iButton Thermochron â data loggers for monitoring the stress response during transport.

“…Importantly, core body temperature is related to rumen temperature, and rumen temperature appears to exhibit a daily rhythm as well. This rhythm in rumen temperature is likely driven by the circadian pattern of feed intake (Piccione et al, 2014). Changes in the phasing of the core body temperature rhythm was greatest when feed availability was restricted to a portion of the day, when compared with the effects of infusing acetate or long-chained FA during a portion of the day (Salfer et al, 2019;Salfer and Harvatine, 2020).…”

Dairy cows have a daily pattern of feed intake which influences ruminal fermentation and nutrient absorption. Milk synthesis also exhibits a daily rhythm and is altered by the timing of feed availability. Nutrients can regulate physiological rhythms, but it is unclear which specific nutrients affect the rhythms of milk synthesis in the cow. The objective of this study was to determine the effect of the timing of acetate infusion on the daily rhythms of feed intake, milk synthesis, milk fatty acids, plasma insulin and metabolites, and core body temperature. Ten lactating ruminally cannulated Holstein cows (127 ± 24.6 d in milk; mean ± standard deviation) were arranged in a 3 × 3 Latin square design. Treatments were ruminal infusions of 600 g/d of acetate either continuously throughout the day (CON) or over 8 h/d during the day (day treatment, DT; 0900 to 1700 h) or the night (night treatment, NT; 2100 to 0500 h). Experimental periods were 14 d with a 7-d washout between periods. Cows were milked every 6 h during the final 7 d of each experimental period to determine the daily pattern of milk synthesis. Blood samples were taken to represent every 4 h across the day and plasma glucose, insulin, β-hydroxybutyrate, urea nitrogen, and acetate concentration were measured. An intravaginal temperature logger was used to measure core body temperature. Data were analyzed with cosinor-based rhythmometry to test the fit of a cosine function with a period of 24 h and to determine the acrophase (time at peak) and amplitude (peak to mean) of each rhythm. Milk yield fit a daily rhythm for all treatments and DT and NT phase-delayed the rhythm and DT increased the robustness of the rhythm. Milk protein concentration fit a daily rhythm for all treatments and DT increased robustness, whereas NT phase-delayed the rhythm. Plasma acetate concentration also fit a daily rhythm in all treatments. Plasma acetate peaked at ~1600 h in CON and DT and at 0053 h in NT, reflecting the timing of treatment infusions. There was a daily rhythm in plasma β-hydroxybutyrate that reflected the plasma acetate rhythm. Core body temperature fit a rhythm for all treatments, but the amplitude of the rhythm was smaller than previously observed. In conclusion, the timing of acetate infusion influences peripheral rhythms of milk synthesis and plasma metabolites.
