The aim of the experiment was to evaluate effects zinc gluconate (ZnGlu) and probiotic administration on daily rhythm cloacal temperature (tcloacal) in broiler chickens different age groups during hot-dry season. One-day-old chicks (n = 60) were divided into I–IV 15 per group, treated for 35 days: Group I (control) given deionized water; II, ZnGlu (50 mg/kg); III, (4.125 × 106 cfu/100 mL), IV, mg/kg) + mL). Air dry-bulb (tdb), relative humidity (RH), temperature-humidity index (THI) inside...

The hindlimb of the grasscutter (Thryonomys swinderianus, Temminck-1827) was studied using 12 adult (≥6 months) rats either sex with mean weights 1.42 ± 0.20 kg and 0.82 0.13 for buck (n = 6) doe 6), respectively (p < .05). Characteristics bones were by gross observation after their preparation. Measurements different segments also taken, giving a total average length 31.80 cm. Correlation coefficients between bone weight positive .05) in bucks all segments, except pes > .05), whereas those...

The present experiment was performed with the aim of investigating effect season on behavioral activities donkeys during rainy and harmattan seasons in Northern Guinea zone Nigeria. Sixteen apparently healthy were used as subjects divided into four groups based age. During each season, donkey evaluated for three weeks using focal animal sampling technique. dry-bulb temperature (DBT), relative humidity (RH), temperature-humidity index (THI) obtained times day experimental period standard...

The aim of this study was to determine the effect season on diurnal rhythms heart (HR) and respiratory rates (RespR) in adult, yearling, foal donkeys during cold-dry hot-dry seasons under natural light/dark cycle. resting HR RespR were recorded bihourly for 24 consecutive hours from 06:00 h (GMT +1) 30, clinically healthy (10 adults,10 yearlings, 10 foals). Dry-bulb temperature (DBT), relative humidity (RH), temperature-humidity index (THI) wet-bulb globe (WBGT) inside pen h. Values DBT,...

The study analyzed climate change information and flood adaptation strategies among rice farmers in Hadejia agricultural zone, Jigawa State, Nigeria. Multi-stage sampling procedure was employed the selecting of 278 respondents for study. Data were collected using structured questionnaire descriptive inferential statistics. results showed that almost all (96%) male over half (53%) age bracket 25 - 40 years while majority (79%) married. finding indicated 48% had household size 1-5 persons 42%...

The study evaluated the effects of graded levels Bactofort® on cloacal temperature fluctuations in broiler chickens during cold–dry season. Complete randomised sampling was used to assign 225 chicks into 5 groups with 3 replicates. from Group I were fed a basal diet without supplementation, II 0.25 g per kg feed, III 0.35 IV 0.45 feed and V 0.55 feed. Beginning day old, treatment supplementation daily for 6 weeks. Dry-bulb (DBT), relative humidity (RH) temperature–humidity index (THI) inside...

The aim of the study was to evaluate oxidative stress and behavioural responses donkeys during cold-dry hot-dry seasons. Thirty divided into three groups ten each according their age served as experimental subjects. During season, blood parameters were evaluated times with an interval one week at 06:00 h, 12:00 h 18:00 (GMT+1). peak dry-bulb temperature (DBT) value 36.00 ± 1.00°C recorded indicating that season induced heat stress. time spent feeding demonstrated diurnal fluctuations in...
