ANIMAL SPECIES-
The world is filled with many various sorts of animals. Some swim and some flies. Some breathe air, and some breath underwater. Some have skeletons, and others don't. Scientists classify the animals into various different groups that share important characteristics. The two main largest groups of animals are vertebrates and invertebrate animals. Vertebrates are animals that have spines or backbones. Invertebrates are animals that do not have backbones. Most of the animals within the world are invertebrates. Some samples of invertebrates are octopus and squid, insects, arachnids, starfish and sea urchins, jellyfish, crabs and lobsters, clams, and lots of more creatures. On land, most invertebrates are small, but within the water, they'll grow an excessive amount of larger sizes, because the water will support them even without a skeleton. Vertebrates structure but five percent of all animal species on earth, but if I asked you to consider an animal you'd choose a vertebrate! Vertebrates are divided into different classes, or groups. Several animals of these classes are specific types of fish, like the jawless fish, like lampreys, hagfish, cartilaginous fish, and sharks and rays. These other classes are usually tangled together with bony fish and are called 'fish.' The four remaining classes of vertebrates will all be very familiar: amphibians, reptiles, birds, and mammals. Let's inspect the characteristics that make an animal a fish. Fish sleep in the water, and that they can breathe underwater. They use gills, not lungs, to urge oxygen from the water around them. Fish have scales and fins. They are cold-blooded animals which means that they cannot control their own body temperature which changes by the temperature of the environment around them. Most fish also lay eggs. Amphibians are a gaggle of animals that include frogs, toads, newts, salamanders, and more. Amphibians, like fish, are cold-blooded. Unlike fish, amphibians can survive on land and within the water and have smooth, moist skin. Amphibians lay their delicate, jelly-covered eggs within the water. When the eggs hatch, the young might not look very similar to their parents, because some amphibians must undergo metamorphosis- or an enormous change - to become adults. Aside from some fish, amphibians are the sole vertebrates that undergo metamorphosis. Reptiles you would possibly know are turtles, snakes, crocodiles, and lizards. Like fish and amphibians, reptiles are cold-blooded. Unlike them, reptiles are air-breathing animals and can't breathe underwater. Even reptiles that sleep in the water must come to the surface to breathe! You can tell if an animal may be a reptile rather than an amphibian if it's dry, scaly skin. Most reptiles lay eggs, but they're very different from the eggs of amphibians or fish. They lay their eggs out of the water and have a hard protective shell. For the foremost part, reptile eggs have soft, leathery shells. Birds are easy to recognize. They are the sole sort of animals within the world to possess feathers! Like reptiles, birds can only breathe air. All birds have two legs, and every one bird even has wings, but not all birds fly. Unlike fish, amphibians, and reptiles, birds are warm-blooded. That means that they will maintain a continuing blood heat. Birds lay eggs but not like the eggs of reptiles, birds lay eggs that have hard shells. The last group of animals we are getting to mention is mammals. Mammals are the main group of animals and also to which humans belong. Like birds, mammals are warm-blooded and breathe air. Even mammals that sleep in water must come to the surface to breathe! All mammals have a minimum of some fur or hair, although some have but others. Almost all mammals give birth to measure young rather than laying eggs, and every one mammal feeds their babies milk. A fun fact about mammals is that mammals are the sole animals to possess ears that stick out! The Animalia is assessed into many various groups that supported animal characteristics to assist us to understand the planet around us. By saying that an animal is an invertebrate, a vertebrate, a fish, an amphibian, a reptile, and a bird.
Animal Classification (9 main Phyla of Animals)-
The 9 main phyla of the Animals are a very diverse and cultural group of organisms. They vary very much from whales to insects. What do all these animals have in common? First of all, they all are multicellular organisms that are made from eukaryotic cells. Each cell has a nucleus and membrane-bound organelles. Next, they are all consumers. Heterotrophs which means they eat other organisms. They all use protein collagen to attach the cell tissues together. Most animals are diploid which means each cell has a homologous pair of chromosomes. This means they have two sets of chromosomes. One from mom and another from dad. Animals develop from an embryo and there is more than 30 animal phylum, but more than 90 percent of animals can be found in the 9 phyla. Phylum Porifera Sponges, Annelida Segmented Worms (earthworms, leeches) Nematoda, The Roundworms Platyhelminthes The Flatworms planaria, tapeworms Mollusks (Mollusca)Includes snails, clams, slugs, squid, and their relatives. Arthropods (Arthropoda). The largest animal phylum, and also they have jointed external skeletons. Echinoderms (Echinodermata)Sea stars and sea urchins. CnidariaJelly fish, the sea anemones. All of this phylum contains the animals that are invertebrates which means they do not have vertebrae or the backbone. Chordates have a backbone (Vertebrae), Chordates (Chordata) Vertebrates-fish, the amphibians, the reptiles, the birds, and the mammals.
ANIMAL HUSBANDRY-
For the development of food resources, not only the plant resources are needed to be improved but animal resources also. We know that animals provide us various types of food items such as milk, egg, meat, poultry, fish, honey, and etc. So, because the population and living standards are increasing, at an equivalent time the necessity for milk, egg, meat is additionally increasing. Thus, there is a need to improve the life stock. It includes various aspects like feeding, breeding, shelter, and disease control. So, now animal-based farming includes various types of farming such as cattle farming, poultry farming, fish production, and honey beekeeping. Let's begin with cattle farming in this lesson. So, cattle farming is completed majorly for 2 purposes: dairy and draught. So, dairy is for milk production and draught is for animals that are utilized in agriculture tasks like plowing, irrigation, and cutting. So, on the idea of those purposes, the cattle are divided majorly into two categories; the milch breeds and therefore the draught animals. Let us see each of them in detail. So the milch breeds or the dairy animals are those animals that are mainly used for obtaining milk and draught animals are those which are mainly used for agriculture and transportation. Now, both of those usually belong to 2 species; either a cow or which may even be called asbos indices, or a buffalo which may even be called asbos bubbles. So, now once we know that mitch animals are used for the assembly of milk, we also know that milk may be a complete food and it's required in huge amount in our country but does one know that milk production up to some extent depends upon the duration of the lactation period. The lactation period means the duration time of milk production after the birth of a calf. Milk production can be increased by increasing the duration of the lactation period. So, to get the desired quality the breeding of animals can be done. For example, exotic breeds like jerseys and Brown Swiss show high or for instance long-duration periods; while the local breeds like Red Sindhi and Sahiwal show excellent resistance to diseases. So, now the 2 can cross spread to get the desirable characters which are the long lactation period and therefore the resistance to diseases. Now, like we'd like proper care and shelter to survive comfortably similarly, these animals also require proper cleaning and shelter facilities to be healthy and also for the clean milk. Animals require proper brushing to get rid of dirt and loose hair. They should be sheltered under-ventilated roofed sheds which will protect them from heat rain and cold. The floor of the cattle shed must be sloping, so on keep it dry and also to facilitate cleaning. Next, the shelter should be spacious enough to stay the animal comfortable and also to avoid overcrowding. So now lastly this shelter should have a correct arrangement of unpolluted beverage. So, these are a number of the details for farm management but a cattle don't only need an honest shelter but it also needs food. The two types of requirements of the dairy animals. First, maintenance required and second, the mill produces requirements. Now, the upkeep requirement includes the food which helps within the regular metabolic activities of the body and therefore the milk-producing requirement includes the food which especially required during the lactation period. If we now see the cattle feed, then we will see that it consists of two major components. The roughage and the concentrate. Let's see what are they; therefore the roughage largely contains fibers like green fodder, hay, and legumes, etc. On the opposite hand, the concentrates are low in fiber but they contained a comparatively high amount of proteins and nutrients like cottonseeds, graham, wheat, etc. So, overall cattle need balanced food, which contains all the kinds of nutrients in a proportionate amount. Now, besides this nutritious food, some amount of nutritionist's feet also can be added which are you recognize just like the micronutrients. These nutrients manage their health and also increases the milk output in dairy animals. There are various cattle diseases and these diseases can be classified into few categories, such as diseases which are caused by parasites, They can be of two types; the first is the external parasites like flies, ticks, and worms they cause this kind of disease and next is the internal parasites like the worms cause internal diseases to the animals. The next category of diseases is communicable or infectious diseases; so as we all know, communicable diseases are caused by pathogens, these pathogens are often bacteria, fungi, or viruses. Next, the last category is non-communicable or non-infectious diseases. These diseases occur thanks to immediately thanks to the deficiency of some nutrients or could also be thanks to malfunctioning of somebody's organ. Now, vaccinations are often given to livestock to stop viral and bacterial diseases. So, as a student during this lesson, you've got to see how cattle farming is often done and the way cattle farming increases the food production for the increasing population.
