Item EFFECTS OF WALLOWING, SEX AND DAYTIME ON THE THERMOREGULATORY RESPONSE OF GEESE AT HIGH TEMPERATURE HUMIDITY INDEX(Proceedings of 26th Annual Conference of ASAN-NIAS, 2021) Ewuola, E.O.; Akinbola, E.T.; Ogundele, A.A.; Oyewale, J.O.24 geese (12 males and 12 females) were used to assess the effect of wallowing on the haematology and thermoregulatory response of geese at high temperature humidity index. The male and female geese were randomly divided each into 2 treatments which were the wallowed group and non- wallowed group and the experiment lasted for 5 weeks. The temperature, humidity, pulse rate, respiratory rate and rectal temperature were measured every alternate day for a period of 5 weeks while the blood samples of the animals was collected and analysed for haematological profile twice during the experiment: 2 weeks post wallowing and 4 weeks post wallowing. Significantly higher values were observed in the respiratory rate and pulse rate of non-wallowed geese than the wallowed geese for the wallowing effect. Sex did not have any significant effect on all the parameters. The values for their respiratory rate, rectal temperature and pulse rate ranged from 20.24±2.48-21.15±3.69 breaths/minutes, 40.42±0.35-40.43±0.450C and 152.74±22.32-156.33±17.43 beats/minutes respectively. Their respiratory rate and rectal temperature were also observed to be significantly higher in the afternoon and evening than in the morning. However, there was no significant difference in their pulse rate. Therefore, this study indicated that wallowing and daytime influenced the thermoregulatory response of the geese at high temperature humidity index.Item Variations in the thermoregulatory response of geese during high temperature – humidity index(Proceedings of 25th Annual Conference of ASAN, 2020) Akinbola, E.T.; Ewuola, E.O.Geese have a seasonal reproductive pattern governed by environmental fluctuation. Birds must therefore be in homeostasis with their environment for optimum performance and reproductive efficiency. In a 21–day trial, the effects of sex and daytime on the thermoregulatory response of geese during high temperature – humidity index was investigated. Twenty four geese (12 males and 12 females) were allotted into two treatments according to their sexes in a completely randomized design. Their respiratory rate, rectal temperature, pulse rate and panting rate were measured and recorded in the morning, afternoon and evening throughout the entire experimental period. Also, the ambient temperature and relative humidity of the pen were recorded on a daily basis. Results showed that females had significantly (p<0.05) higher respiratory rate and pulse rate than males. However, males had significantly (p<0.05) higher rectal temperature than the females. The panting rate was not significantly different (p>0.05) between the two sexes. The respective mean temperature, humidity and temperature-humidity index values recorded were 26.59oC, 85.65% and 40.69 (morning); 34.16oC, 46.05% and 48.25 (afternoon) and 34.39oC, 47.45% and 47.84 (evening). The rectal temperature in the morning was significantly (p<0.05) lower than in the afternoon and evening and their pulse rate decreased (p<0.05) inversely with daytime. Hence, it can be concluded that sex and daytime independently has effect on the thermoregulatory response of geese.Item VARIATIONS IN THE THERMOREGULATORY RESPONSE OF GEESE DURING LOW TEMPERATURE – HUMIDITY INDEX(NIGERIAN SOCIETY FOR ANIMAL PRODUCTION (NSAP) 46TH ANNUAL CONFERENCE, 2021) Akinbola, E.T.; Ewuola, E.O.; Olujimi, A.T.In a 28–day trial, the effects of sex and daytime on the thermoregulatory response of geese during low temperature – humidity index was investigated. Twenty four geese (12 males and 12 females) were allotted into two treatments according to their sex in a completely randomized design. Their cloaca temperature, respiratory rate and pulse rate were measured and recorded in the morning, afternoon and evening for the entire experimental period. Also, the ambient temperature and relative humidity of the pen were recorded daily. Males had significantly (p < 0.05) higher respiratory rate (20.84±2.06 breaths/minute) than females (19.49±1.37 breaths/minute). However, pulse rate and cloaca temperature were not significantly (p > 0.05) different between the two sexes. The respective mean temperature, humidity and temperature-humidity index (THI) values recorded were 25.20±1.460C, 91.93±4.38% and 24.92±1.38 (morning); 28.98±1.870C, 73.64±9.00% and 27.74±1.37 (afternoon) and 28.88±2.300C, 72.39±8.87% and 27.60±1.86 (evening). The cloaca temperature in the morning was significantly (p < 0.05) lower than in the afternoon and evening while their pulse rate and respiratory rate were not significantly (p<0.05) different at the respective daytimes. Hence, sex and daytime independently influenced the thermoregulatory response of the geese.
