Environmental Modification And Stress Management
Gbogbo ọrọ náà
Two farmers in the same town keep the same breed of pig. One farmer's animals grow steadily and breed well through the hottest months of the year. The other's go off their feed every afternoon, pant in a huddle in the corner of a bare concrete pen, and take weeks longer to reach market weight. The difference is rarely the pig. It is almost always the shed: shade, airflow, spacing and a little water make the difference between an animal that copes with Nigeria's climate and one that is fighting it every single day.
In this lesson you will learn what environmental modification means and the practical methods a farmer uses to keep animals comfortable in both heat and cold, what stress in a farm animal actually is and the many things beyond climate that cause it, and the management practices that keep stress low enough for an animal to grow, breed and produce at its best.
