Animal Health Management: Parasites

<h1>ANIMAL HEALTH MANAGEMENT</h1> CONTENT <ol> <li>Meaning of Parasites</li> <li>Types of Parasites</li> </ol> <ul> <li>Ecto-parasites - Ticks, Lice, Mites, Flies</li> <li>Endo-parasites - Tape Worm (<em>Taenia spp), </em>Round Worm (<em>Ascaris lumbricoides</em>), Liver Fluke (<em>Fasciola hepatica</em>)</li> </ul>   <h2>Meaning of Parasites</h2> Parasite is an organism which lives on or inside the body of another organism called the host in order to derive all its nourishment such as food, shelter and protection. The parasite does not provide any benefit but causes damage or harm to the host in return. The host usually belongs to a different species and is often bigger and stronger than the parasite. Sometimes the relationship with the parasite causes the death of the host or reduces its productivity. The relationship between the parasite and the host is known as Parasitism. Based on this relationship, a parasite may be temporary, (living for a short period in or on the host) or permanent, (living their entire lives in the host e.g. endo-parasites)   <h2>Types of Parasites</h2> Livestock parasites are grouped into two namely; <ol> <li>Ecto-parasites</li> <li>Endo-parasites</li> </ol>   <h3>1. Ecto-parasites</h3> These parasites live outside or on the hosts. They usually attach themselves to the skin of the animals. Ecto-parasites include ticks, lice, mites, fleas, flies, etc. <h4>(i) Ticks</h4> Ticks affect livestock such as cattle, sheep, horses and dogs. They live all their lives attached to the hosts and suck blood except during the period of mounting and reproduction. Tick belongs to the order of Acarina and the class Aranchinda.   <h5>Classification of Ticks</h5> <h6>(a) Classification of Ticks based on Mode of Development</h6> <ol> <li><strong>One Host Tick</strong>: All stages of development takes place in one host animal e.g. blue tick.</li> <li><strong>Two Host Tick</strong>: The lava develops into nymph on the first host. The nymph falls off and moults into adult which attaches to the secondary host e.g. red legged tick.</li> <li><strong>Three Host Tick</strong>: These attach to different animals at each stage of development, drop off and moult into the next stage on the ground e.g. water tick.</li> </ol>   <h6>(b) Classification of Ticks based on Body Texture</h6> <ol> <li>Hard tick (Ixodidae)</li> <li>Soft tick (Argasidae)</li> </ol>   <h5>Life Cycle of Host Tick</h5> <img class="size-full wp-image-56041 aligncenter" src="https://classhall.com/wp-content/uploads/2019/08/life-cycle-of-host-tick.jpg" alt="Animal Health Management - Parasites - Life Cycle of a Host Tick" width="499" height="408" /> Ticks are important arthropods and vectors of infectious diseases. They carry both viruses and protozoan producing organisms. When unfed they are flat, but spherical when engorged with blood of warm blooded vertebrates. They are unisex, the female after mating sucks blood many times until it increases in size. The stages of development: Eggs → Larva → Nymph → Adult Ticks have eight walking legs. Their eggs are laid on the ground and larva emerges to climb grass or shrubs and attaches to any passing animals. The eggs hatch out in about 3-4 weeks depending on the climatic condition.   <h5>Economic Importance of Ticks</h5> <ol> <li>Loss of blood and weight</li> <li>Reduction in quality of hide and skin which lead to reduction in market value</li> <li>Reduction in the production of meat and milk</li> <li>Restlessness caused by skin irritation</li> <li>Loss of farmers’ income</li> <li>Injuries from bite causes secondary infection</li> <li>It causes and transmits diseases such as heart water disease, red water disease, anaplasmosis, tularemia, typhus, etc.</li> <li>It produces substance which causes toxic effect on animals</li> <li>Transmitted diseases may cause death and eventually reduce number of stock</li> </ol>   <h5>Control of Ticks</h5> Ticks can be controlled by the following: <ol> <li>Good sanitation</li> <li>Regular dipping in solution of acaricides</li> <li>Spray animals’ beddings with insecticides</li> <li>Adopt rotational grazing</li> <li>Burning of infected pasture</li> </ol>   EVALUATION <ol> <li>State the classification of ticks and give examples for each.</li> <li>Why is the control of ticks necessary in animal production?</li> </ol>

The damages done by pests include: (i) Some insect pests are carriers of diseases which they transmit to healthy plants. Examples of diseases transmitted by insect are: ground nut rosette, cassava mosaic, swollen shoot of cocoa, etc. (ii) Mammals (rodents) e.g. rats, grass-cutter eat up the tubers of yam, cassava and potato.

Role of Government in Agricultural Development

<h1><strong>ROLES OF GOVERNMENT IN AGRICULTURAL PRODUCTION</strong></h1> CONTENT <ol> <li>Roles of Government in Agricultural Production</li> <li>Government Organisations Involved in Improving Agricultural Production in West Africa</li> </ol>   <h2><strong>Roles of Government in Agricultural Production</strong></h2> In the past, agriculture used to be the mainstay of the Nigerian economy but when petroleum was discovered, agriculture was neglected, food production became relatively low and a lot of money was spent importing food from abroad. To solve the numerous problems which resulted in the poor development of agriculture, the government has to play an important role in the development of agriculture. The role of the government in agricultural production is broadly given as these two major roles: (a) To set up good and functioning policies (b) To formulate good and functioning programmes   (a)<strong> To set up good and functioning policies</strong> A policies is a set of rules set up by the ministry/government towards achieving a goal. Policies sometimes changes as government changes, but the basic objectives of a good policy may include the following: (i) To provide both qualitative and quantitative food (ii) To produce animals and plants that are rich in protein and at a minimum cost for both rich and poor in the society. (iii) To increase the supply of animals and plants that can attain market weight in the shortest possible time (iv) To develop local agro-based industries that will employ the citizen as well as provide finished products. (v) To increase the supply of local raw materials like timber, cotton, groundnut, gum Arabic etc. (vi) To produce plants and animals for export purpose. (vii) To regulate the influx of foreign agricultural products so as not kill agro-based industries in the country. (viii) Mechanizing farming for increased output and income for farmers.   (b) <strong>To formulate good and functioning programmes</strong>

Food is the major requirement of the body for substance and maintenance of all physiological, anatomy and pathological functioning. When food is lacking the body becomes lifeless. Hence the study of food is very important. Food given to livestock is called feed. The feed is needed forenergy, growth, repair of worn out tissues and general good health of the animals. A nutrients is any element or compound present in the food required by the animal for proper body functioning. A feed is any food substance which when fed to animals is capable of providing some of the nutrients necessary for up keep to that animal. Nutrition is defined as the science of feeding and nourishing the body. It is the series of processes by which an organism takes in or ingests, digests and assimilates food for promoting growth and for the replacement of worn out tissues. Animal nutrition can then be defined as the science of feeding an animal with an appropriate diet capable of nourishing the animal for growth, development, reproduction and repairs of worn out tissues. Therefore the ingredients used for making the feeds must have the following nutrients in adequate quantities and required proportions: (a) Carbohydrates (b) Proteins (c) Vitamins (d) Minerals (e) Crude fibre (f) Fat (g) Water   <h2>Factors that Determine the Nutritional Requirements of an Animal</h2> The level of nutrient or nutritional requirement of animal depend on the following factors: <ol> <li>Age of the animal – young grower</li> <li>Class of animal – egg producer, ruminant or non-ruminant, meat animal</li> <li>Production level – growers, young layers and old layer dry sow</li> </ol>   <h2>Reasons for Feeding Farm Animals</h2> Feeds are fed to farm animals for the following purposes: <ol> <li>To provide necessary elements for repairing the wear and tear of the body to provide raw material for synthesis of body source in growth.</li> <li>To serve as a source of energy for vital processes in the body e.g growth, work, reproduction, respiration digestion etc. For generating heat necessary for maintaining body temperature. To serve as raw materials for the production of milk meat egg wool, etc.</li> </ol>   <h2>Classification and Characteristics of Feed</h2> Animal feed stuffs are classified on their chemical nutritional composition, bulkiness and use. The chemical composition or nutrients gives the potential value of the feed but does not give the actual value. Feeds can be classified into the following:
