Veterinary Vaccine Imports in Algeria: An Econometric Analysis, 2013–2020

Abstract

Veterinary vaccines play a central role in preventing infectious animal diseases, protecting livestock health, and supporting the stability and productivity of animal-production systems. This study investigates the relationship between veterinary vaccine imports and selected livestock and poultry indicators in Algeria over the period 2013–2020. The analysis considers the monetary value of veterinary vaccine imports as the dependent variable and examines chicken meat production, cattle population, and sheep population as explanatory variables. Descriptive statistics, Pearson correlation analysis, and multiple linear regression were employed to assess the relationships among the variables and to identify their individual and joint contributions to variations in veterinary vaccine imports. The findings reveal statistically significant relationships between veterinary vaccine imports and the three production and livestock indicators. Chicken meat production and cattle population exhibit negative relationships with vaccine imports, whereas sheep population shows a positive relationship. Among the explanatory variables, chicken meat production presents the strongest statistical significance, followed by sheep population and cattle population. The overall results support the proposed hypotheses and highlight the relevance of livestock and poultry production indicators in understanding patterns of veterinary vaccine imports in Algeria. The study provides an econometric perspective that can contribute to the analysis of animal-health product demand and the planning of livestock health and disease-prevention strategies.
