Abstract

Stress comes in many forms for livestock, including physical, chemical, nutritional, thermal, and psychological stress. Changes in skin temperature, heart rate, respiration rate, and rectal temperature are indicators of physiological reactions to heat stress. Regression investigation of the physiological reactions of Nigerian native goat breeds (West African dwarf and Red Sokoto) to heat stress was the goal of this study. 400 goats (200 West African Dwarf and 200 Red Sokoto) from Osun, Ondo, and Ekiti states in Nigeria were subjected to varying climatic conditions (temperature and humidity) in order to gather data on physiological indicators (rectal temperature, pulse rate, and respiration rate). An analysis of variance (ANOVA) was performed to evaluate variations in the physiological parameters, and the temperature and humidity index (THI) was computed for the study's environmental conditions.  The coefficient of determination (R2), which represents the accuracy of the predictions, was calculated using regression analysis. The results demonstrated that both breeds' physiological characteristics reacted similarly, with higher THI values considerably increasing heart rate, respiration rate, and rectal temperature. Regression evaluation indicated that THI had a significant (P ≤ 0.05) and positive effect on heart rate (R² = 0.545), respiration rate (R² = 0.32), and rectal temperature (R² = 0.146) for the Red Sokoto breed. These physiological adaptations enable goats to survive and thrive in challenging and variable environments.

Abstract

Three hundred and ninety-nine (399) West African dwarf goats from the Ejigbo Local Government Area in Osun State and the surrounding Derived Savanna Zone of Nigeria were evaluated for body measures and live weight. Analysis was done on data pertaining to 194 bucks and 205 does. These were categorized into six age groups (milk teeth, 2-teeth, 4-teeth, 6-teeth, 8-teeth, and worn teeth) and recorded by sex. The purpose of the study was to characterize the phenotype of the WAD goat and identify the best model or models for predicting liveweight based on body measures in the experimental location, which is Nigeria's derived savanna zone. For both sexes, body measurement values rose significantly (P < 0.05) with age. In bucks, the average body weight was 5.32 ±0.15 to 29.63±1.88 kg, while in does, it was 5.75±0.13 to 30.29±1.22 kg. In terms of body weight and other physical parameters, sex variations were discovered. For quantitative features including heart circumference, body length, rump height, foreleg height, and withers height, the fitted linear regression equations also show that the coefficients were positive and significant (P < 0.05). Moreover, at all ages, multiple regression considerably increased the coefficient of determination (R2) (P < 0.05). In summary, body weight and linear body measurements are economically significant characteristics in animal genetic resources, particularly for small ruminants like goats during selection, to offer precise weight determination in isolated locations without a scale.

Abstract

This study examined the effect of breed on serum biochemical profiles and haematological markers in heat-stressed West African dwarf and Red Sokoto goats. The Temperature Humidity Index (THI) was computed using the recorded ambient temperature and relative humidity of the research. 95 goats in the Nigerian states of Osun, Oyo, and Kwara—50 Red Sokoto and 45 West African Dwarf goat breeds—had blood collected from them, all of whom appeared to be in good health. Haematological parameters (Packed Cell Volume (PCV%), haemoglobin (Hbxg/dl), red blood cell counts (RBC x /µl), white blood cell counts (WBC x /µl) and serum biochemistry, which includes total protein (TP x g/dl), albumin (ALxg/dl), globulin (GL x g/dl ), albumin and globulin ratio (AL/GL%), glucose (GLU x Mg/dl), sodium( x mmol/L), potassium ( x mmol/L) and calcium ( x mmol/L) concentrations in RS and WAD goat breeds were carried out. The results of the investigation showed variations in haematological and biochemical parameters between breeds.

Abstract

HSP90 and HSP70 genes (markers) were used with 45 genomic deoxyribonucleic acid (DNA) isolated from West African Dwarf goat breeds in Nigeria to determine the expression patterns amongst the heat shock protein genes. Polymorphism information content (PIC) of marker; was determined to ascertain the informativeness of the marker.  Fourty five numbers of samples were obtained from WAD goats which were apparently healthy from Osun, Oyo and Kwara State of Nigeria.   At the time of collection, the ambient temperature (0°C) and relative humidity (RH) (percent) were also recorded and this revealed that all the sampled animals were heat stressed.  Polymerase chain reaction (PCR) was carried out using each marker (heat shock protein gene) , isolated DNA, doublen distilled water and PCR Master Mix. PCR products generated were subjected to polyacrylamide gel electrophoresis on an ABI 3730 DNA Sequencer. DNA bands were scored based on size of ladder with Gene Scan 3.1.2. Bands obtained were designated as alleles and prepared into Excel Worksheet with Microsatellite Analyzer version 4.05 software and allele frequencies were generated. The results revealed allele A and C as major allele by marker SSR1 (HSP90) and marker SSR2 ( HSP70)  genes respectively with percentage value of allele A slightly higher than C , effective number of alleles for all loci of SSR1 was lower than the SSR2.. The heighest (Ne1) expected heterozygousity value of 0.40 was revealed by marker 2(HSP 70 gene) as against the lower value of 0.36 revealed by marker 1 (HSP 90 gene) in WAD goats.   PIC per gene or marker across populations ranged from 0.55 (HSP90 ) to 0.59 (HSP70) indicating that the markers were informative (PIC ≥ 0.50). In conclusion, the two markers (HSP 90 and HSP 70) could therefore be serving as bio-markers for selection and breeding programmes for thermo- tolerance in livestock animals especially WAD goats under thermal stress.
