They are used for carrying loads, ploughing, harrowing and ridging e.g cattle, [Sokoto Gudali, White Fulani], (in forms of bull and bullock). Such animals are called <strong>draught animals.</strong> The normal output of a working bull is about 500W compared to that of a man which about 75W. Work animals are also used for transportation and carrying of load e.g. horses, camels and donkeys. Such animals are referred to as <strong>beasts of burden.</strong> They have the ability to survive or travel long distance without water. <h4><strong>Characteristics of Work Animals</strong></h4> The following are the characteristics of work animals: <ol> <li>They are well built with good body conformation.</li> <li>They can survive or travel long distance without water.</li> <li>They are rugged and have very great strength.</li> <li>They have strong hind limbs.</li> <li>They are docile and tolerant.</li> </ol> <img class="size-full wp-image-32367 aligncenter" src="https://classhall.com/wp-content/uploads/2018/11/work-animals-bull.jpg" alt="Farm Animals - Work animals - bull" width="304" height="208" />

Factors Affecting the Distribution of Livestock in Nigeria

<h1><strong>FACTORS AFFECTING THE DISTRIBUTION OF LIVESTOCK IN NIGERIA</strong></h1> CONTENT <ol> <li>Factors Affecting the Distribution of Livestock in Nigeria</li> <li>Table Showing Terms Associated With Some Farm Animals</li> </ol>   <h2><strong>Factors Affecting the Distribution of Livestock in Nigeria</strong></h2> The population of certain kinds of farm animal is more in certain areas than in others. There are factors responsible. Up to 80% of grazing livestock is to be found in the savanna zone of northern Nigeria. This is because of the following factors: 1. <strong>Food/Availability of good pasture</strong>: This constitutes the bulk of the feed of livestock. Large expanse of grassland is abundant in northern Nigeria, and for this reason there is greater population of cattle, sheep and goats, which graze on the pasture grasses and legumes found in this area than in southern Nigeria. 2.<strong> Climate: </strong>Animal production is usually affected adversely by too hot or too cold weather conditions. For instance, pigs do not have sweat glands, so they do not perspire; rearing them in a hot climate will greatly reduce their efficiency. Moreover, the growth and multiplication of pests and diseases is also encouraged by high temperature and rainfall, and this hinders the growth and performance of livestock.
