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

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

This study evaluates the growth performance, feed intake, sensory attributes, and blood profile of male guinea fowls (Numida meleagris) fed different cereal-based diets. A total of 100 male guinea fowls were randomly assigned to three dietary treatments containing maize, millet, or sorghum as primary energy sources. The experiment lasted eight weeks, with data collected on body weight, feed conversion ratio (FCR), meat quality, and blood parameters.Results showed that millet-based diets significantly improved growth performance during the starter phase (P < 0.05), with higher body weight (135.75 g at 4 weeks) and average daily gain (3.95 g/day) compared to maize (109.95 g, 3.00 g/day) and sorghum (128.10 g, 3.65 g/day).** Feed intake was highest in millet-fed birds**, though differences were not statistically significant (P > 0.05). Feed conversion efficiency was slightly better for millet-fed keets (FCR = 3.17) compared to sorghum (3.47) and maize (3.67).Sensory evaluation revealed that millet-fed guinea fowls had slightly superior flavor, juiciness, and tenderness scores, though variations across diets were not statistically significant (P > 0.05). Blood profiles remained within normal ranges, indicating that all diets supported adequate health.These findings suggest that millet-based diets optimize early growth and meat quality in guinea fowls, making them a cost-effective alternative to maize in poultry nutrition. Future research should explore long-term economic benefits and the feasibility of integrating millet into large-scale commercial feed formulations.
