INTRODUCTION

Rajasthan is the largest state of the country with a geographical area of 342,239 Km₂ which constituents 10.41% area of the country. The state can be divided into four major regions; the Western desert with barren hills, level rocky and sandy plains; the Aravalli hills running south west to north-east; eastern plains with rich alluvial soils; and south-eastern plateau. The state has varied climate from semi -arid to arid. The average rainfall in the state ranges from 480 mm to 750 mm, being as low as 150 mm in arid region and 1000 mm in south-eastern plateau (FSI 2009). The recorded forest area is 32,639 Km2 which is 9.54 % of the state’s geographical area. The maximum forests are found in the Districts of Alwar, Banswara, Baran,, Bundi, Chittorgarh, Dhaulpur, Dungarpur, Jhalawar, Kota, Rajasamand, Swaimadhopur, Sirohi and Udaipur. The hot arid and semi-arid regions in the country accounts for 20 % of the country’s geographical area spread over seven states namely Rajasthan, Gujarat, Andhra Pradesh, Punjab, Haryana, Karnataka and Maharashtra. It comes nearly 31.63 m ha out of which 19.61 m ha alone is in the states of Rajasthan (62.00 % of total arid region). This area is characterized by low erratic rainfall, high temperature and wind velocity, coarse textured soils with low organic carbon and soil fertility status and poor water holding capacity. The underground irrigation water is limited and highly saline in most of the cases (Chandra 2005). Mono-cropping is a gamble in arid tract of Rajasthan due to low and erratic rainfall and frequent occurrence of drought during crop growth period leading to complete crop failure. To avoid complete crop failure the farmers are adopting mixed cropping system from very ancient time. But the system is not perfect during the adverse climatic situation due to low yield, long duration of traditional varieties and unmatched crop combinations. Therefore, in mixed or multi cropping system, the choice of drought hardy, short duration varieties of crops are necessary to ensure the production of crops even under adverse situations. It has been seen that drought occurrence during month of July and August leads to 67-100 percent decrease in production of pearlmillet and short duration pulses which are the main crops of the region grown under rainfed condition.
The people in arid regions of India, since time immemorial has developed location specific agroforestry systems. The scattered trees /shrubs in the agricultural fields are common features of the landscape. Since the beginning of cultivation the farmers deliberately allowed the trees/shrubs to grow with crops. These trees provided them insurance during drought years and provided fodder, fruits, vegetables, timber, fuel, fiber etc. during lean period.

Abstract

Trichoderma species play a vital role in the management of plant diseases in association with different commercial bioformutlations of the fungus. Its role as a successful pollution free environment and friendly mechanism of action has been highly exploited. The diversity of species based on location, type of agri-land and association with different fauna  and flora has been instrumental in large upsurge of biological methods of Plant disease management. Pollution of agri-land soils with chemicals, heavy metals and development of resistance to diseases has become an emerging problem coupled with the high costs of Infrastructure. Thus, the interest in alternative biologically based systems is the need for bioremediation, bioecology and biocontrol with Trichoderma.

In tropics, many crops are grown for their edible roots or tubers. Broad group of “tuber crops” encompasses a wide range of starchy food crops, some of which are true botanical roots and some others are stem tubers or corms. In global scenario, they are in a neglected state mainly due to their negative image as poor people’s food. They are highly perishable and are normally consumed locally in fresh or home processed state. It is time to bring out the positive attributes of these important foods and the increased contribution they can make to the nutritional welfare, food security and economic wellbeing of people, especially in developing countries.

Cookware is food preparation equipment, such as cooking pots and pans, used in kitchens. There are several different types of pots and pans- nonstick, ceramic, stainless steel, cast-iron and more. If you’re only going to buy one, we suggest a heavy-duty, try-ply or multi-clad stainless steel pan. They’re expensive, but they’ll last a lifetime with proper use.

Potting and repotting is an essential practice to be done in a nursery to maintain the expected vigour of the plant. When a seedling from a seedbed or plant from a flat bed or raised bed is planted in a pot, it is called potting. The same term is utilized when the bulbs of bulbous plants are planted in a pot. When a plant is transferred from one pot to another pot, it is called repotting. At the time of repotting the plants may be planted in a large pot or in the same sized pot. Repotting is necessary when

1. Plant is grown for a season or a year in the same pot and becomes pot bound resulting in extensive growth of roots in rooting media and there is very little scope for further fresh growth.
2. When a plant is overgrown and requires separation or division.
3. When soil gets depleted of its nutrients.
4. Repotting affords an opportunity to the roots to form a new root growth, as repotted soil contains sufficient amounts of nutrients and good aeration.

Purpose- Burnt porous clay or cement or plastic pots are commonly used for various purposes in horticulture. The pots are used in propagation or plants, cultivation of ornamental plants and flowering annuals. Growing of plants in pots in referred as pot-culture. In pot-culture, operations such as potting, shifting and filling of pots are very important. Potting refers to planting of plants in pots containing soil mixture, while shifting means removal of plants from pots and planting them again in the same or different pot. Plants growing for more than one year in the same pot need shifting. The time for potting and shifting of plants is monsoon season (July to Sept.) and during spring (Feb-March).

Materials and Equipments-Flower pots, crocks (broken pieces of pots), potting mixture, khurpi and watering can (with fine nozzle).

Mixed and Integrated Poultry Farming

Mixed farming refers to the practice of cultivating crops and rearing livestock on the same farm, aimed at maximizing economic benefits through the efficient use of resources. This type of farming can be practiced either simultaneously or at different times, depending on the needs and conditions. In India, mixed farming is particularly significant as it typically contributes at least 10% of a farmer’s income from livestock, potentially reaching up to 49%.

Advantages of Mixed Farming

• Maximized Returns: By-products of farm activities, such as crop residues, can be effectively utilized to feed livestock, leading to higher returns.

• Year-Round Employment: Mixed farming provides continuous work opportunities throughout the year, ensuring a steady income.

• Efficient Resource Utilization: The combination of crops and livestock ensures optimal use of land, labor, and capital.

• Soil Fertility: Livestock manure contributes to maintaining and enhancing soil fertility, which is crucial for sustained crop production.

• Balanced Food Production: Mixed farming allows for the production of a variety of food items, leading to a more balanced diet throughout the year.

For maximization of productivity in any kind of poultry venture the knowledge on the behaviour of birds and its application play very significant role. Behaviour is the reaction of the whole organism to certain stimuli, or the manner in which it interacts to its environment. Behavioural patterns are not inherited as such, but develop through the process of growth and get differentiated under the influence of genetic and environmental factors. Primary function of behaviour is to enable the bird to adjust itself to some changes in condition, whether external or internal. Most animals have a behavioural pattern which can be tried out in a given situation and in this way they learn to apply one or the other according to that which produces the best adjustment.

Origin of Fowl

Domestication of poultry seems to have been undertaken in south-east Asia. The chickens were brought to India by 1000 BC, and later on they spread north, westwards and reached Greece by 525 BC. By the beginning of Christian era, the birds were already popular in West Asia and East Europe, and then gradually reached South Africa, Australia, Japan, USSR and USA.

Red Jungle fowls are the ancestors of the present-day poultry breeds. There are four known species of wild fowl and they belong to the same genus “Gallus” meaning a cock. The four species are as follows:

The Red Jungle fowl is supposed to be the main contributor for the development of modern-day poultry and is widely distributed throughout Burma, China, India, Philippines, Sumatra and Thailand. The plumage (colour of the feather) of females resembles that of Brown Leghorn, the males have orange red feathers in hackle, wing bow and saddle regions, while the breast is black. Eggs are buff (off-white) in colour. The legs are slate (dark bluish grey) coloured. The comb is all red.

Genetic Classification of Poultry

Understanding the genetic classification of poultry is essential for breeders and farmers to optimize the performance and standards of different commercial breeds. Here’s a detailed overview:

Evolutionary Background

• In the process of evolution, cold-blooded (poikilothermic) reptiles are considered the ancestors of birds.

• Birds are warm-blooded (homeothermic) feathered creatures adapted for hot and dry climates in their terrestrial habitats.

Chromosomal Categories

• Sex Chromosomes: Carry genetic material that determines the sex of an offspring.

• Autosomes: Non-sex chromosomes that carry the bulk of genetic information.

Abstract

Climate change and variability can adversely affect the poultry production in India, because birds can only tolerate narrow temperature ranges. Thermal stress on poultry is major concern. Heat and clod stress can cause immunosuppression and make birds more prone to infectious diseases. Climate change affects the occurrence, distribution and prevalence of poultry diseases.  Nutritional strategies aimed to alleviate the negative effects of heat stress by maintaining feed intake, electrolyte and water balance or supplementation of micronutrients such as vitamins and minerals to satisfy the special needs during heat stress have been proven advantageous. Ventilation and cooling methods are essential for birds to survive high summertime temperatures. Tunnel ventilation coupled with evaporative cooling is very effective in keeping birds cool during hot weather. The increasing proportion of poultry production in tropic and subtropical region makes it necessary to reconsider the selection strategy and potential use of naked neck and frizzle genes for improving heat tolerance in chicken.

18.1 Introduction

The egg industry has grown quickly in the last decade as people’s eating habits have become more aware of the importance of good and nutritious diets. Eggs are now widely accepted as a good source of high-quality protein. However, at the same time, the eggshell that pollutes the environment is discharged into the open. This eggshell waste can be used to make a variety of items, including pharmaceuticals and medicines. Additionally, this raw material is inexpensive and conveniently accessible. Eggshells are ranked as the fifteenth biggest environmental pollutant.

Introduction

Civilization of mankind began with the process of domestication of livestock and poultry. The Indian Red Jungle fowl is considered as the ancestor of modern day chicken breeds. Chickens were first domesticated in S E Asia (India, Southern China, Burma, Malaya region) between 5000 – 3000 BC and then spread westwards and then Africa, Europe and America. Poultry in India was a leisurely and backyard village venture till sixties. The entire poultry scenario of Indian sub-continent changed only in last 4-5 decades and now India ranks 3rd in egg production (3.9%) after China (45%) & USA (8%) and 5th in broiler production (3.3%) after USA (26.5%), China (17%), Brazil (15.5%) & Mexico (4.3%) with about 54,000 and 1800 million eggs and broilers produced annually. But in terms of per capita availability it ranks amongst the lowest. Poultry production systems of the developing nations including India can be broadly categorized into two distinct classes: one - low external input traditional family poultry production system or free range or backyard poultry in unorganized sector in the villages and the other one is high input industrial or intensive poultry production system in urban and peri-urban areas. The former is highly unorganized and consists of thousands of small holders (5-15 birds) where birds scavenge and forage on house-hold wastes, shrubs, weeds, crop residues, insects and aquatic plants with no or little external inputs.

Introduction

A hatchery is such a facility where eggs are hatched under artificial conditions, especially those of poultry eggs. Poultry hatchery produce a majority of bird’s chicks by hatching their eggs including chicken, turkey, ducks, quails, goose and some minor bird species. A broiler breeder produces about 150-180 fertile eggs in a year of reproductive life. This reproductive capacity can’t be utilized without liberating the breeding hen from incubating eggs. In India, there is huge demand of day old chicks for commercial poultry farming and for that there is great scope for hatchery business. The competition in the hatchery industry is increasing day by day for efficient production of quality chicks economically. Therefore, it may be necessary for the hatchery man have thorough understanding of the basic and practical aspects of incubation and hatchery operation for efficient working.

Housing of Poultry

Proper housing is essential for successful poultry farming, as it directly impacts the health, welfare, and productivity of the birds. Well-designed poultry housing not only provides protection and comfort but also ensures efficient management and optimal environmental conditions for the flock. This chapter explores the key aspects of poultry housing, including its purpose, site selection, and layout considerations.

Purpose of Poultry Housing

• Protection and Comfort: Provides a safe environment that shields birds from predators, harsh weather, and other external threats.

• Health and Welfare: Ensures optimal health and well-being by preventing diseases and reducing stress.

• Management: Facilitates easy and efficient management of the flock in a controlled and scientific manner.

• Cost Efficiency: Reduces overall production costs through efficient resource management.

Housing constitutes the second largest component of cost of poultry production. An ideally located and well planned poultry farm is an essential requirement for efficient egg and meat production. Poultry housing normally serves the following major functions:

Provides shelter and protection to the birds

Provides comfort to the birds.

Helps in organization of large flock into a manageable unit.

In India, poultry judging refers to selection of birds on the basis of their physical appearances, breed characteristics and production performances; however, in other countries, like USA judging is also used for eggs, carcasses and further processed products. The Directorate of Extension, Ministry of Agriculture, Govt. of India annually conducts livestock and poultry shows in various parts of the country in collaboration of state governments. Besides, state Agricultural/ Veterinary Universities or other institutions also conduct such shows. In these shows judging contests are carried out mostly for the undergraduate students by using a score card to grade birds either for production characters or breed characters. The winners are awarded trophies and cash prizes. The birds meant for judging are kept in individual cages and the participants are requested to score under various sub-headings and to finally rank the bird. Any deviation from “ideal” or “perfection” (as described by the American Standard of Perfection or the British Poultry Standards) but not serious enough to constitute a disqualifications in the show room is considered to be a defect. Serious defects are regarded as disqualifications and will bar a bird from winning any prize. Both layers and broilers can be physically evaluated for their performance rating.
