A. Answer the following questions

1.    Define feeding standards?

Ans: Feeding standards are the statements or quantitative descriptions of amounts of one or more nutrients needed by the animals or human.

2.    Limitation of feeding standard?

Ans: Palatability and physical nature of the ration are not included and does not included the environmental factors because environment may change the nutrient requirements.

3.    Write down the merits of ME system?

Ans: ME gives more correct result than DE or TDN. It is because energy losses in urine and GDP are corrected in ME system and ME is cheaper and easier to obtain than NE values.

4.    What is the purpose of following feeding standard?

A fish is defined as the cold blooded vertebrates, which catch with the help of gills and swims with the help of fins and which are aquatic in nature. In broader sense the term fishery is used for the rearing and management of all aquatic animals which are useful to human being e.g. fishes, crustaceans and mollusks. The term fishery science is related to the rearing and management of fish on large scale by proper utilization of available water sources.

Fishes comprise of about 33100 species (FishBase 2015) differing widely from each other in shape, size, habits and habitats. Some of them are very small or more than an inch in length, while a few attain a length up to 18.50 m. they live in all free flowing rivers, lake, canals, dams and in almost every place where there is water.

Fishes usually have a stream lined body but some are elongated snake like and a few are dorso-ventrally compressed. They have paired and unpaired fins supported by soft or spiny fin rays. Dorsal, caudal and the anal fins are unpaired while the pectorals and pelvic (ventral) are paired fins. A number of species possess barbless which are excellent organs of touch.

Silage is the material produced by controlled fermentation of forages or crop residues with high moisture content. The objective of silage making is to preserve the harvested forages by anaerobic fermentation in which soluble carbohydrates are converted into acids. Due to acid produced, pH of a well-ensiled product becomes so low that all life processes come to a halt and the material remain preserved so long as it remains in airtight storage. Soluble carbohydrate present in forage is converted to lactic acid which drops the pH to a level sufficient to inhibit any further biological activity in the ensiled forage mass (McDonald, 1991). Fresh forage crops, such as maize, grasses, legumes, wheat and Lucerne, can be preserved by ensiling. It is essential to have a good microbial fermentation process to produce high quality silage. Good silage is achieved by discouraging the activity of plant enzymes and undesirable micro-organisms and encouraging the dominance of lactic acid bacteria. A good fermentation process is not only dependent on the type and quality of the forage crop, but also on the harvesting and ensiling technique. Silage-making is a managemental tool that allows producers to match feed resources (forages, crop residues, agro-industrial byproducts, etc.) with feed demand for a dairy herd.

Origin of fruit culture can be traced back to 8000-5000 years ago and the horticultural practices like irrigation, vegetative propagation, selection etc. developed about 5000-3000 years back. The sophisticated fruit culture might have originated before 3000-2000 years. Basically all the cultivated fruits are the gift of diversity and not results of systematic breeding. Most of them have spread to different parts of the world through various media from the primary centres of origin.

Centres of origin of major fruit crops are as follows:

Mediterranean basin : datepalm, fig, grape, olive, pomegranate

East Asia : banana, citrus, mango, peach, kiwi fruit, persimmon

Central Asia: pome fruits, apricot

Europe : plum, raspberry

North and South America: avocado, black berry, papaya, pineapple, strawberry

The history of gardening dates back to the history of human civilization. In order to meet various utility purposes, primitive people used to grow plants initially. Some of them had beautiful flowers and drew attention. Gradually, the importance of growing flowers / ornamental plants for worshiping Gods and Goddesses came into existence. The need for growing plants for aesthetic purpose came much later. Development of formal gardens also initially confined to temples and, thereafter, attached to the residential places. Concept of developing parks and gardens for beautification purpose exclusively for public use came much later during 17^th century. With the influence of different regimes as prevailed in India time to time, the gardening styles and plants also changed a lot for fulfilling new taste and need of the people.

Gardens have played a very important role in development of nations of the world. In fact, humanity started its cultural development from a garden rememberd as ‘Garden of the Paradise’. Gardens always occupied a prime place in our social and cultural life. Every race has its own idea of gardening and the characters of the nation is expressed in its gardens and parks.

The status of gardening during ancient time has been presented in Ramayana, written by Valmiki. Ayodhya city was described as having wide streets, large houses, richly decorated temples and gardens. These gardens were planted with fruit trees and flowering plants and had lakes full of lotus (Nelumbo sp.) and different kinds of birds. During exile, Lord Rama and Sita are believed to have observed a number of trees and were fascinated by beautiful flowers; one of them was Sita Ashok (Saraca asoca).

Mahabharata, written by Saint Vyasa also contains description about gardens. During the Mahabharata era, pleasure gardens were planted with flowering plants. The famous tree of this era was Kadamba (Anthocephalus cadamba), which is associated with Lord Krishna.

The systematic gardening in India is as old as civilization of Indus of Harappa, which existed between 2400 B.C. and 1750 B.C. At that time, people were living in well-planned roads cut across one another almost at right angles. There are many evidences which prove that trees and ornamental plants were associated with the Harappan civilization. India has a long history of close association of people with flowering plants. It begins with the arrival of Aryans to India in 1600 B.C. They were literate people and brought with them the four Vedas viz., Rig veda, Atharva veda, Yazur veda and Sam veda and the Puranas. They appreciated the beauty of flowering plants, lakes, mountains, forests, etc. and named their children after flowers like Kamal, Champa, Bela, Chameli, Rukmani, etc. The followers of Hindu religion worship their Gods and Goddesses with flowers early in the morning.

The life of Lord Buddha was associated with a number of trees from birth to his Nirvana. He was born in 563 B.C. under the tree of Ashoka (Saraca asoca) at Lumbini. Further, Buddha attained his enlightenment under a Pipal (Ficus religiosa) tree, spread his new teachings under shady banyan and mango trees and breathed his last in a Sal (Shorea robusta) grove.

When Lord Buddha visited Vaishali, Amrapali presented a park known as Amravana which was dominated by flowering trees. Buddhists were planting trees and flowering plants on a large scale for making surrounding peaceful and place ideal for meditation.

The history of genetics dates from the classical era with contributions by Hippocrates, Aristotle and Epicurus. Modern biology began with the work of the Augustinian friar Gregor Johann Mendel. His work on pea plants, published in 1866, what is now Mendelian inheritance. Some theories of heredity suggest in the centuries before and for several decades after Mendel›s work. The year 1900 marked the “rediscovery of Mendel” by Hugo de Vries, Carl Correns and Erich von Tschermak, and by 1915 the basic principles of Mendelian genetics had been applied to a wide variety of organisms—most notably the fruit fly Drosophila melanogaster. Led by Thomas Hunt Morgan and his fellow «drosophilists», geneticists developed the Mendelian model, which was widely accepted by 1925. Alongside experimental work, mathematicians developed the statistical framework of population genetics, bringing genetic explanations into the study of evolution.
With the basic patterns of genetic inheritance established, many biologists turned to investigations of the physical nature of the gene. In the 1940s and early 1950s, experiments pointed to DNA as the portion of chromosomes (and perhaps other nucleoproteins) that held genes. A focus on new model organisms such as viruses and bacteria, along with the discovery of the double helical structure of DNA in 1953, marked the transition to the era of molecular genetics.
In the following years, chemists developed techniques for sequencing both nucleic acids and proteins, while others worked out the relationship between the two forms of biological molecules: the genetic code. The regulation of gene expression became a central issue in the 1960s; by the 1970s gene expression could be controlled and manipulated through genetic engineering. In the last decades of the 20th century, many biologists focused on large-scale genetics projects, sequencing entire genomes.
Pre Mendelian Ideas on Heredity
Diagram of Charles Darwin’s pangenesis theory. Every part of the body emits tiny particles, gemmules, which migrate to the gonads and contribute to the fertilised egg and so to the next generation. The theory implied that changes to the body during an organism’s life would be inherited, as proposed in Lamarckism. Mendel’s work

The homoeopathic system of medicine is one of the finest systems of cure available in the world. It achieves in totality the ideal laid down by its founder, Dr. Samuel Hahnemann:

"The highest ideal of cure is rapid, gentle and permanent restoration of the health, or removal and annihilation oftlie disease in its whole extent, in the shortest, most reliable, and most harmless way, on easily compreltensible principles".

In homoeopathy, not a single drug is used without knowing its effect on healthy human beings. Hence there is no shooting in the dark. The system operates, by and large, without laboratory tests and other expensive means of diagnosis, which are being used when not needed and that too, unfortunately on patients who can hardly afford the expenses.

Cost wise, there is no medical system in tlie world, which is as inexpensive as homoeopathy. No patient who requires a speedy cure without side effects can ignore homoeopathy; no doctor who has nothing but the good of his patient at heart can overlook the utility and effectiveness of homoeopathy and no Government which has to balance its budget can afford not to use homoeopathy in hospitals and other institutions run for the health and care of the sick and thus it is the most cost effective treatment

The discovery of homoeopathic system of medicine makes a fascinating story.

Origin of systematics is as old as Vedas (1500 BC), Ramayana (1900 BC), Mahabharat (1400 BC) and Upanisad (350 BC) in which mention had been made about various animals.

History of Insect Classification

Linnaeus (1758-1766) in the 12th edition of Systema Naturae, divided insects into 9 orders

1. Coleoptera (earwigs – Dermeptera).

2. Orthoptera.

3. Hemiptera.

4. Lepidoptera.

5. Neuroptera (ant lion, Sialis, termites and dragon flies).

6. Hymenoptera

7. Diptera.

8. Thysanoptera.

9. Aptera (wingless insects, spiders, scorpions, terrestrial crustacians and Myriapods).

Introduction

The history of Integrated Pest Control goes back much farther than the mere coining of the term in the early fifties and the subsequent elaboration and clarification of the concept. The origins are deeply rooted in the evolution of pest control practices as developed by Entomologists and Plant Pathologists in the Nineteenth Century.

Human history is a series of attempts to gain increasing control over the environment. At first this control was minimal to the degree that poor shelter and unstable food supplies imposed severe population constraints. The gradual gain in man’s capacity to control his environment parallels the gradual rise of civilization. But as man aggregated into villages near rivers and planted crops near by, he encountered increasingly severe attacks by pests on the crops. For thousands of years, man could do nothing about these pests but appeal to the power of magic and a variety of gods. For the most part, early humans had to live with and tolerate the ravages of plant diseases and insects, but gradually they learned how to improve their conditions through “trial and error” experiences. These improvements included the beginnings of pest control or pest management, the most preferred term today.

1.1 Introduction
The concept of invention is the fundamental requirement for design thinking. Since the birth of mankind, people started inventing many concepts, which are mainly observations of facts and innovation of ideas for producing products that are useful to the society. The design thinking requires unconventional thinking to design processes for maximal operational efficiency of manufacturing the products, which give maximum satisfaction to customers with more value for money. Hence, the team that is involved in the design thinking projects may gain the required skills by knowing several inventions of the past. Hence, a review of inventions is presented in this chapter.
1.2 Tracing Inventions
The content at https://www.explainthatstuff.com/timeline.html gives a complete account of inventions starting from 4–5 billion years ago up to 2022. The article on solar cell energy gives an account of the sun started producing energy. About 1.2 million years ago, humans invented fire, which has been further innovated for biofuels, candles, IC engines, aviation engines, etc. In the 7th century B.C., ants were killed by burning in the heat produced by concentrated sun rays using magnifying lens. Greeks and Romans utilised burning mirrors to light candles during religious ceremonies in the third century B.C. About 3.5 million years ago, stone, wood, antlers, and bones were used by humans to make first kind of tools. These were further improved to make tools for machines. About 4000 BCE back, iron was used to make decorative ornaments. About 3500 BCE, people invented the concept of wheel, which brought quantum revolution in transportation.

Obviously human have had to deal with microbes even before the recorded history. The first record of human using microorganisms comes from ancient tablets from mid east.

Babylonians were using yeast to make beer over 8000 years ago and acetic acid bacteria to make vinegar over 6000 years ago. About 5000 years ago, Persia (Now Iran) region recorded the wine making.

The Romans had God for specific microorganisms. The roman God of mold and mildew were “Robigus” and “Robigo” which mean crop rust. (Rust is one of the plant disease caused by fungus). God Robigus was very much feared because of crop lost. About 2000 years ago, Romans proposed that diseases were caused by tiny animals. But, fundamentalist religions had a strong hold over the progress. The real microbiology history starts from 1600s, when people began to make crude lenses and microscopes.

The following are the scientists and their role in the development of microbiology:

Microorganisms (or microbes) are organisms too small to be seen with the naked eye. The science of microbiology is the study of microorganisms, their properties, classification, growth requirements, method of reproduction and distribution in nature. These organisms range in size from tiny viruses to larger bacteria, protozoa, algae, fungi and some of the microscopic worms (helminthes). They are present everywhere in our environment, in our homes, on our bodies, on the things we touch and on the food we eat. They are important for human survival on Earth, playing an essential role in many processes that maintain life. In nature, microorganisms carry out a number of important functions.

1.They are responsible for the decomposition of organic matter.

2.Recycling of nutrients that help to maintain the balance of chemicals in the soil.

3.Special nitrogen-fixing bacteria live symbiotically with certain plants, absorbing nitrogen from the air and converting it into compounds which can be used by the plant for growth.

4.Some algae are capable of photosynthesis, using energy from the sun to convert carbon dioxide in air into carbohydrate.

5.Marine microorganisms form the basis of the food chain in lakes, rivers and oceans.

6.Certain microorganisms are used in the manufacture of food.

7.Pharmaceuticals and drugs.

8.Industrial processes.

9.A valuable tool for scientific research.

10.Use in laboratory experiments to understanding metabolic pathways and in the discovery of the genetic code.

WORLD HISTORY

Work on ornamental crops was first initiated in Krelage Nursery founded by Ernst Heinrich Krelage for bulbs, lilium and dahlias in 1811. During 1895, Taiwan Agricultural Research Institute was established for ornamental crops. The first yellow corn Golden Bnatam was listed in Burpee’s Catalogue in 1902. In 1909 Primadonna F1 hybrid variety of begonia was released by the Benary Seed Company in Germany and in the same year Atlee established seed farms at Floradale in California, Erfurt in Germany Anglia in UK and Kashmir valley in India for annual garden flowers. Luther Burbank did excellent breeding works on ornamental trees, flowers and fruits in 1926.

David developed the first successful hybrid in Nasturtium (1934) and Red and Gold hybrids of marigold (1937). In 1940, Burpee was successful in chromosome doubling and transformation of wild flowers and developed “Bright Scarlet” and “Super Tetra Series” in antirrhinum and “Jumbo Scarlet” in zinnia. He produced new strains of marigold, zinnia, nasturtium and snapdragon. William Houston in 1940 initiated the Ageratum breeding. Morden Research station was set up in Western Canada in 1945 for ornamental crop breeding. In 1968, Dr. Gustav A.L., Mehlquist was recognized as an international authority on breeding of ornamental plants. George J. Ball breeder of peas, asters and calendulas was a pioneer for the supply of dwarf impatiens and orange impatiens ‘Super Elfin’ in 1968. Israeli breeders during 1990 gave more attention towards the development of carnation, lily and anemone varieties. Longwood Gardens in 2008 got success in breeding of stock. The first record of chrysanthemum hybridization, germination and selection of superior seedlings occurred in 1827 by M. Bernet.

It will be unjust not to describe history of Parasitology (31) and a little bit about Parasitology (chapter 8) so that our students may know the earlier works done in this field and how research has advanced by diligent observations of the eminent scientists when they were not having such sophisticated facilities.

As helminth is visible with naked eyes, it was this parasite which man encountered first in its journey of life sciences or natural sciences,as was known in ancient times. Some of these were known even before the era of biblical Palestine and ancient Egyptian civilization. Hippocrates (460-357BC), ‘Father of Medicine’ knew about pinworms (Oxyuris equi) of horses. In his “History of Animalium”, Aristotle (384-322 BC)(32) has mentioned three kinds of helminthes-flatworms, cylindrical worms (Ascaris lumbricoides) and thinworms (Enterobius vermicularis). The treatises of India had the information on large roundworms of intestine (Ascaris), pinworms, leeches, bed bugs and mosquitoes.

The history of plant breeding is divided into 4 periods- knowledge of plant breeding before 1900, application of genetic principles (1900-1940), plant breeding research after 1940 and the recent developments in plant breeding. Emphasis is given on the land marks in genetic improvement of vegetable crops.

The major land marks  in genetics and breeding of crop plants are listed below.
