Morphometric Evaluation of Gross Pulmonary Indices in the Red Sokoto Goats for Pulmonary Consolidation Assessment

Abstract

Goats are widely adapted to different climates and are found in all production systems. However, very little is known on the pulmonary morphometry of indigenous goats in Africa. The study aims to determine the standard morphometry and dimensions of the Red Sokoto RS goat lungs, which may serve as basis for clinical and radiographic assessment of pulmonary consolidation. The goats were sourced from a Municipal abattoir considering age and sex. A total of 35 non‐pneumonic RS lungs were collected including 22 males and 8 females, 6 between <1 years, 15 between 1–2 years and 9 > 2 years. Weight (gram), length (cm) and diameter (cm) of each lung lobe, distance from trachea bronchus to point of trachea bifurcation, distance between left and right trachea bifurcation were taken using standard measurements. The right lung contributes the most (61.67%) while the left lung contributes the least weight (38.32%). Of the 61.67% contributed by the right lung, the caudal lobe contributes 38.9% while the cranial (14.71%), middle (5.83%) and accessory (1.53%) lobes makes up the remaining. It was also discovered that the caudal lobe of the right lung contributes more than the left lung. The percentage contribution of right lung lobes increased with increase in age except for the accessory lobe which decreased with increasing age. The percentage contribution of the left lung lobes decreased with increasing age except for the middle lobe which was increasing with age. The right lung is longer (6.70±0.57) than the left lung (13.40±0.82). The right cranial lobe is longer and wider than the left cranial lobe. The right middle lobe is insignificantly longer (1.20±0.57) than the left (1.10±0.22) but significantly less wide (6.7±0.57) than the left (7.72±1.14). The right caudal lobe is longer (8.76±0.25) than the left (8.50±0.50) but less wider (4.86±0.20) than the left (5.5±0.61). The males have higher weight and dimensions than females except that the values of the right lung, the caudal lobe of the right lung and the middle lobe of the left lung are higher in females than in males. In conclusion, this study established the standard as regarding the normal size of each lung lobe and lobule in relation to the age and sex of the RS goat. These parameters will aid diagnosis of lung disease and assessment of pulmonary consolidation at postmortem in a poor resource setting.This abstract is from the Experimental Biology 2019 Meeting.
