Daily rhythms of rectal and body surface temperatures in donkeys during the cold-dry (harmattan) and hot-dry seasons in a tropical savannah

Effects of melatonin on hematologic and biochemical changes and the effects of circadian rhythm on hematologic changes in donkeys (Equus asinus) subjected to packing during the hot‐dry season

“…It has already been established that a THI value above 78 is very stressful for donkeys. 38 The result of THI obtained in the afternoon hours, ranging from 78 to 82 in the present study, demonstrated that the afternoon hours were thermally stressful to the donkeys, which is in agreement with previous results obtained in this equatorial zone. 39,40 The hematologic parameter results obtained indicate that packing without melatonin decreased the PCV.…”

Modulatory roles of melatonin on respiratory and heart rates and their circadian rhythmicity in donkeys (Equus asinus) subjected to packing during the hot-dry season

“…The result of this study has shown that packing of the donkeys during the hot-hours of the day beginning from 12 to 18:00 h should be reduced or completely avoided in order to minimise the negative impact of environmental stress on the donkeys. The finding agrees with the observations of Zakari et al (2018a) , who obtained high values of environmental parameters during the photophase, especially at 15:00 h of the day.…”

“…The result of the meteorological parameters obtained in the experiment indicates that the thermal environmental conditions were stressful to the donkeys, especially immediately after packing period of 12–13:00 h. The THI value above 78 has been established to be very stressful to animals ( Habeeb et al, 2018 ; Lallo et al, 2018 ; Zakari et al, 2018a ). The afternoon THI that fluctuated between 78 and 82, in the current study shows that the afternoon hours were thermally stressful to the donkeys, which agrees with the finding of previous study ( Zakari et al, 2020 ).…”

Parâmetros Clínicos E Bioquímicos De Jumentos Da Raça Pêga No Primeiro Mês De Vida

“…M0= momento zero; M1= momento um; M2= momento dois; M3= momento três; M4= momento quatro; M5= momento cinco; Letras divergentes na mesma linha, diferem entre si pelo teste de Tukey a 5% de probabilidade (p<0.05). Os valores de FR encontrados no presente estudo, em todos os momentos de análise, foram superiores aos descritos por Zakari et al (2018). E a diferença estatística observada nos neonatos desta pesquisa pode estar associada as condições ambientais de altitude, temperatura, clima e umidade do local onde fica situado o criatório.…”
