It involves mating, after which the male sperm is united to the female ovum to form zygote.   <h2>The Male Reproductive System</h2> The male reproductive system is made up of the primary sex character (testes) and the secondary sex character which consist of the scrotum, cowpers gland, prostate gland, seminal vesicle, urethra, penis, vas deferens and spermatic ducts. <img class="size-full wp-image-55164 aligncenter" src="https://classhall.com/wp-content/uploads/2019/10/male-reproductive-system.jpg" alt="Reproduction and Reproductive Process in Farm Animals - Male Reproductive System" width="694" height="404" /> <img class="size-full wp-image-55165 aligncenter" src="https://classhall.com/wp-content/uploads/2019/10/male-reproductive-system-spermatozoa.jpg" alt="Reproduction and Reproductive Process in Farm Animals - Male Reproductive System - Spermatozoa" width="526" height="239" />   <h3>Functions of Various Parts of Male Reproductive System</h3> <strong>Testes</strong>: They are located within the scrotum or scrotal sac. When stimulated by the male hormone called testosterone, it secrets spermatozoa. <strong>Scrotum</strong>: This helps to house the testes. It regulates the temperature of the testes at 4⁰C less than the body temperature. <strong>Vas deferens</strong>: This is responsible for conducting sperm from the epididymis to the neck of the urethra.

A disease is also defined as a condition of disorder in the functioning of the tissues of an organism. It is an unfavorable condition caused by infections by pathogens or deficiency or excess of some environmental factors which result in physiological and anatomical dysfunctions expressed in characteristic symptoms.   <h2>Diseases of Major Crops</h2> The following are the diseases of major crops: (i) Cereals – Smut, rice blast, etc. (ii) Legumes - Cercospora, leaf spot, rosette, etc. (iii) Beverages - Cocoa black pod, coffee leaf rust, etc. (iv) Tuber - Cassava mosaic, bacterial leaf blight, etc. (v) Fruits - Citrus Gummosis, Diebacks, etc. (vi) Fiber - Black arm (bacterial blight of cotton) (vii) Vegetables - Root knot of tomato or okra, etc. (viii) Stored produce - Mould   <h2>Causes of Diseases</h2> <h3>(i) Pathogen Diseases</h3> These are diseases caused by living microorganisms called pathogens. e.g.

<h1>PESTS OF CROPS</h1> CONTENT <ol> <li>Meaning of Crop Pests</li> <li>Classification of Crop Pests</li> <li>Name and Description of Important Insect Pests</li> </ol>   <h2>Meaning of Crop Pests</h2> A pest can be described as an organism, whether plant or animal, which causes economic damage to crop plants, livestock, man and his possessions. They attack crops on the field as well as in the store. They may harm crops directly or introduce diseases into them. Examples of pests are insects, rodents, higher parasitic plants, etc.   <h2>Classification of Crop Pests</h2> Pests are classified in different ways as follows: <ol> <li>Insect pests</li> <li>Non-insect pests</li> </ol>   <h3>Insect Pests</h3> These are the most serious pests of agricultural importance, and the group includes all insects which cause damages to crops and crop products. Examples of insect pests are grass hopper, weevils, beetles, white flies, termites, crickets and locusts. They feed on crops either on the field or in the store.   <h3>Non-insect Pests</h3> These are organisms other than insects which attack and feed on crops. They cause a lot of damages to crops though they are not as many as insect pests. Examples of non-insect pests include rodents like giant rats, grass cutter, monkeys, nematodes and birds. <img class="size-full wp-image-53333 aligncenter" src="https://classhall.com/wp-content/uploads/2019/08/non-insect-pests.jpg" alt="Pests of Crops - Non-insect pests" width="650" height="139" />   <h3>Classification of Insect Pests Based on Mouth Parts/Mode of Feeding</h3>

They attack crops like fruits, grains, oil palm, etc. while on the field. For example, the weaver birds called Quela bird feed on millet, sorghum and rice. They eat the developing seeds and cause great losses on crops. Francolin feeds on tuber crops like cassava, yam, cocoyam and grain crop. Parrots also eat lots of fruits such as mango and cocoa. Weaver birds cause defoliation to oil palm leaves, reducing photosynthetic activities of the crops. <h3>Rodents</h3> These are mammalian pests which damage crops like young oil palm trees, vegetables, yam, cassava, rice and sugar-cane. Examples are rats, monkeys, giant rats, bats, squirrel, grass cutter and antelope. Squirrels and monkeys eat cocoa pods; bats eat lots of fruits like oranges and mangoes. Ground squirrel eats or digs out and eats newly planted seeds. Grass cutter cuts and eat cereals, cassava, sugar cane and young oil palms. Rats eat and destroy stored produce like grains and tubers. <h3>Nematodes</h3> These are species of worm present in the soil. From the soil, they enter into the root of crops like tomatoes and okra where they cause the root to grow swellings called root knots. When this happens the plants have stunted growth and reduced yield <h3>Snails</h3> They are serious pests and they feed on leaves and reduce their photosynthetic ability, yield and quality of vegetables.   <h3>Nature of Damage to Crops</h3> The nature of damage by some selected crop pest are shown in the table below:

They are plants which grow where they are not wanted. They can also be defined as”plants out of place”. They are usually unwanted, uninvited quests on farms.Also ,their growth interfere with that of cultivated crops and therefore constitute nuisance to crops, livestock or even man. An edible crop could become a weed if it grows where and when it was not planted, example maize growing on a land where cassava is planted is a weed.   <h2>Common Weeds</h2> Some of the common weeds include:

Farm animals vary in their individual characteristics. These include avian species, mammalian species and aquatic species. <img class="size-full wp-image-53393 aligncenter" src="https://classhall.com/wp-content/uploads/2019/08/farm-animals.jpg" alt="Types and Classification of Farm Animals" width="462" height="388" />   <h2>Types of Farm Animals</h2> <h3>(i) Avian Species</h3> This group belongs to all domesticated birds such as domestic fowl, ducks, turkeys, geese, guinea fowl, swarms, pigeons, pheasants, canaries and ostriches. These lay eggs and are therefore refer to as Oviparous animals. <h3>(ii) Mammalian Species</h3> This group consists of the domestic four-footed animals which include cattle, sheep, goat, pigs, horses, donkeys and camels. They give birth to their young ones alive and as such, they are referred to as Viviparous animals. <h3>(iii) Aquatic Species</h3> This group consists of animals living and reproducing in both fresh and salt water bodies eg fishes, crabs, snails, crustaceans etc. EVALUATION <ol> <li>Define the term farm animals.</li> <li>State the three major types of farm animals and give two examples.</li> </ol>   <h2>Classification of Farm Animals</h2> Farm animals are generally classified on the basis of their habitat, uses, digestion, reproduction, etc. <h3>A. Habitat</h3> Classification under habitat comes under three major divisions, namely;

<h1>ANATOMY, PHYSIOLOGY AND REPRODUCTION OF FARM ANIMALS</h1> CONTENT <ol> <li>Parts of Farm Animals</li> <li>Organs of Farm Animals</li> </ol>   <h2>Parts of Farm Animals</h2> Anatomy can be defined as scientific study of parts and structures of farm animals while physiology refers to the way in which the bodies of farm animals function. The understanding of these helps the farmers to know how they function and be able to manage the animals effectively. Animals’ body can be broadly divided into four, namely: <ol> <li>The Head: This consists of the uppermost parts of the animals’ body. The most important organs that are necessary for the survival and effective functioning are found in the head e.g. brain, eyes, ears, nose and mouth.</li> <li>The Thoracic Cavity: This consists of the chest region of the animals. It houses important body organs such as the heart, the lungs and Trachea.</li>
