Chapter One — 1.1 Background to the Study

Research interest in vaccination regimen has grown steadily in recent years, driven by its demonstrated relevance to pigs in both laboratory and field settings.

Much of the existing literature on vaccination regimen draws on data and conditions that differ from the local context in which pigs is typically studied or produced, limiting the direct applicability of prior findings to weight gain.

1.2 Statement of the Problem

There is currently limited empirical evidence on how vaccination regimen affects weight gain in pigs, making it difficult for researchers and practitioners to draw reliable, context-appropriate conclusions. This study addresses that gap through a structured investigation.

1.3 Objectives of the Study

1. To determine the effect of vaccination regimen on weight gain of pigs.
2. To evaluate the extent to which vaccination regimen influences weight gain.
3. To identify the conditions under which vaccination regimen has the greatest effect on weight gain.
4. To recommend practices based on the observed relationship between vaccination regimen and weight gain.

1.4 Research Questions

1. What is the effect of vaccination regimen on weight gain of pigs?
2. To what extent does vaccination regimen influence weight gain?
3. Under what conditions does vaccination regimen have the greatest effect on weight gain?
4. What practices can be recommended based on this relationship?

1.5 Significance of the Study

This study is significant to researchers and practitioners working with pigs, offering evidence on how vaccination regimen relates to weight gain. It also contributes to the broader literature in animal science by documenting findings specific to the conditions under which the study was conducted.

1.6 Scope of the Study

The study is limited to examining Vaccination Regimen and its relationship with weight gain in pigs, reflecting a BSc-level scope of analysis; conclusions are drawn strictly from the conditions and samples used in the study.
