The Revised ATMA Scheme provides for dedicated specialist and functionary support to take up training and extension initiatives at State, District and Block level. Besides this, improvement in extension outreach right down to the village level is expected to be achieved through Farmer Friend. The study mainly focused on farmer friend under ATMA scheme. The FF served as a vital link between extension system and farmers at village level (one for every two villages). The FF should be available in the village to advise on agriculture and allied activities. The FF  mobilized farmers’ groups and facilitate dissemination of information to such groups, individual farmers and farm women directly through one to one interaction individually or in groups and also by accessing information / services  on behalf of farmers as per need through Common Service Centres (CSC) / Kisan Call Centres (KCC). (Government of India, 2010).

Introduction

Fisheries sector, a sunrise sector in India, has recorded a faster growth than that of crop and livestock sectors (Kumar et al., 2006). The sector contributes to the livelihood of a large section of economically-underprivileged population of the country. It has been recognized as a powerful income and employment generator as it stimulates growth of a number of subsidiary industries and is a source of cheap and nutritious food besides being a foreign exchange earner (Ayyappan and Krishnan, 2004).

With the changing composition pattern, emerging market forces and technological developments, it has assumed added importance in India. It is undergoing rapid transformation and the policy support, production strategies, public investment in infrastructure, and research and extension for fisheries have significantly contributed to the increased fish production. Particularly, after the mid-1980s, the development of carp polyculture technology has completely transformed the tradition backyard activity into a booming commercial enterprise. The aquaculture in the East Godavari delta region prospered with good yields and export driven demand. The paddy belt of the area rapidly converted into aquaculture hotspot owing to high economic benefits. But in recent years the dwindling of aquaculture and frequent losses caused and forced the farmers to withdraw from the once profit driven occupation. Apart from economic analysis, the motive behind this investigation is to find the efficiency of the farmers and the determinants. This will be useful in finding the lacunae in existing system of culture and will address necessities for shifting to new alternative.

ABSTRACT

The Kolanthamamalai hill an offshoot of Kalakadu Mundanthurai Tiger Reserve of Southern Western Ghats is one of the important forest reserves of Tirunelveli District. The physiography of this range differs much from the adjacent portions of Southern Western Ghats of Tamil Nadu state due to its discontinuity, varying altitude, ridges and their height and breadth. The altitude of the hilly rugged terrain ranges from 150 to 300m, with the highest peak being Kolanthamamalai. Field visits were made in the study area to survey and to gather information on medicinal flora. The vegetation of Kolanthamamalai hill is a mixed dry deciduous type characteristic of the high and low altitude of the mountains respectively. Lowland vegetation girdles the base of the mountain on the eastern and southern side of the hills. Along the foot hills vegetation is an open scrub with occasional trees. The low-lying areas and the seasonal watercourses are densely vegetated. The natural barriers, habitat diversity, climate and moderate rainfall have resulted in the development of unique plant diversity.

Introduction

For capacity building of farming community, training plays a vital role. It helps in enriching the knowledge along with enhancement of essential skill required in performing certain practices in a specific crop cultivation. The skills required by a coconut cultivator need to be supplemented with additional skills in order to increase the yield of nuts. Government provide better support to the coconut growing farmers to improve their income, to reduce the risk involved in cultivation, implementation of quality agricultural practices and f inally enhancing the income of coconut grower in business mode. Training is a source of information, advice and influence in the decision making process. Training helps in enhancement of knowledge, improvement of skill, interaction with experts and to build confidence. Keeping this in view, the present study was conducted to know the training need areas of coconut growers in Gop block of Puri district of the state of Odisha.

1. Introduction

Sustainability embodies an ecological vision aimed at fostering enduring human coexistence on Earth. Over time, its definition has evolved in literature and context, generating ongoing debate. Generally, experts frame sustainability around three pillars: social, economic, and environmental. While environmental concerns often dominate discussions, sustainability encompasses broader challenges like pollution, land degradation, biodiversity loss, climate change, and ecosystem service decline. This concept influences decision-making globally, politically, and personally.

Sustainable development, often used interchangeably with sustainability, is distinguished by UNESCO as a long-term objective versus the diverse processes and pathways to achieve it. Within the economic dimension, the tension between welfare and environmental preservation is explored through concepts like “weak and strong sustainability,” acknowledging the necessity of trade-offs. Ideal policies would aim to decouple environmental degradation from economic growth.

Environmental sustainability is pursued through various means such as ecosystem preservation, collaborative resource management, reducing food waste, advocating plant-based diets, managing fertility rates to curb population growth, and transitioning away from fossil fuels towards clean energy and innovative green technologies.

ABSTRACT

An Expert System also called a Knowledge Based System is a computer program designed to simulate the problem-solving behavior of an expert in a narrow domain or discipline. In agriculture, expert systems unite the accumulated expertise of individual disciplines, e.g., plant pathology, entomology, horticulture and agricultural meteorology, into a framework that best addresses the specific, on-site needs of farmers. Expert systems combine the experimental and experiential knowledge with the intuitive reasoning skills of a multitude of specialists to aid farmers in making the best decisions for their crops. The various expert systems were developed since evolution of Artificial Intelligence. This paper compares the availability of various expert systems in agriculture for last 30 years.

Introduction

Agricultural production has evolved into a complex business requiring the accumulation and integration of knowledge and information from many diverse sources. In order to remain competitive, the modern farmer often relies on agricultural specialists and advisors to provide information for decision making. Unfortunately, agricultural specialist assistance is not always available when the farmer needs it. In order to alleviate this problem, expert systems were identified as a powerful tool with extensive potential in agriculture.

Dr. Chauhan, a renowned figure in the field of veterinary science, has left an indelible mark on the discipline through his groundbreaking research, innovative teaching, and unwavering dedication to the advancement of animal health and welfare. Over the years, his exceptional contributions have earned him a multitude of prestigious awards, medals, and honors, making him a luminary in his field.
His illustrious career began to gain recognition with the Best Young Scientist Award in 1992by Indian Association of Veterinary Pathologists, an acknowledgment of his potential and early contributions to veterinary science in general and Veterinary Pathology in particular. This award marked the start of a journey filled with accolades that would underscore his relentless pursuit of excellence. Four years later, in 1996, he was honored with the IAAVR Award, further solidifying his position as a promising researcher and academic.
By 1999, Dr. Chauhan’s expertise and dedication had earned him the National Fellow Professor chair of ICAR, a prestigious recognition that highlighted his growing influence in veterinary research. Around the same time, he was conferred the title of Fellow NAVS (2000) and Fellow SIIP (2001), reflecting his significant contributions to national and international veterinary organizations. These fellowships were a testament to his role in advancing scientific understanding and his collaborative efforts within the veterinary community.
Dr. Chauhan’s profound impact on the field was also recognized with several specialized awards, including the K.S. Nair Memorial Award in 1999, the Vigyan Bharti Award in 2000, and the Dr. C.M. Singh Trust Award in 2002. These honors celebrated his ability to merge academic rigor with practical applications, benefiting both the academic community and the agricultural
sector. Similarly, the Dr. Rajendra Prasad Award (2002) and the Shri Ramlal Agrawal National Award (2000) underscored his contributions to veterinary science in India.

Accidental sampling: Accidental sampling as quota sampling is based upon the convenience in accessing sampling population. While quota sampling attempts comprise people possessing an obvious/visible characteristic, accidental sampling makes no such effort. Any person that comes across can be contacted for participation in the study. Collecting data are stopped when reaching the required number of respondents decided to have in the sample.

Abattoir is a structure meant to recover the edible portions of slaughtered animals for human consumption. These structures are used to cater the need of domestic purposes as well as some of them are utilized for export purposes. The demand of Indian meat and meat products is increasing day by day not only in our country but also around the globe. Therefore, millions (about 15 million cattle and buffalo and 1 million sheep and goat) of food animals are slaughtered every year to meet the current demand. Such large scale slaughter of food animals generates huge amount of wastes but due to lack of proper sanitary measures in majority of slaughter houses of our country their wastes not only deteriorate the hygiene of meat and meat products but also pose a potential threat to the environment. Therefore, it is an urgent need for safe and proper disposal of slaughter house and meat processing waste for food safety and human health. It is also important to protect the environment and to improve the quality and hygiene of meat and meat products.

By-products or offal’s are basically every part or particle which is not included in dressed carcass. It can also be explained as everything produced from the animals except dressed meat is considered as by-products. Meat industry now demands the full utilization of by-products to make the industry profitable and economically sustainable. It is also important for environmental management and to enhance the social image of the meat industry. The yield of animal by-products ranges between 50-60% of the live weight.

LUMBAR VERTEBRAE

Ox: The lumbar vertebrae are characterized by elongated flattened transverse processes (projecting outwards) and large, strongly curved articular processes (Fig.5.1a). The body is constricted in the middle and expanded at the extremities. The anterior extermity is less convex and posterior is less concave. The posterior vertebral notches are much deeper. The intervertebral foramina are often double in the anterior part of the series and are very large further back.

The abdominal aorta is the continuation of thoracic part of the descending aorta which enters the abdominal cavity through hiatus aorticus of the diaphragm. After entering the abdominal cavity it passes caudally below the bodies of the lumbar vertebrae and psoas minor muscle in contact with the left crus of the diaphragm and the ventral common vertebral ligament. After reaching at the fifth or sixth lumbar vertebra, it terminates into iliac quadrification by dividing into two common iliac arteries. Each of the common iliac arteries further divides into internal and external iliac artery. The internal iliac artery supplies arterial branches to the wall and the viscera of the pelvic cavity while the external iliac artery supplies arterial branches to the pelvic limb of the corresponding side. The abdominal aorta is related dorsally to the bodies of lumbar vertebrae, ventral common ligament, tendon of left crus of diaphragm and psoas minor muscle, ventrally to the pancreas and rumen, on its right to the caudal vena cava and on its left to the left adrenal, left kidney and left ureter. The abdominal aorta gives out parietal and visceral branches that supply the walls and the viscera of abdominal cavity.

Parietal branches

The parietal branches of the abdominal aorta are the six pairs of the lumbar arteries. Out of these, four or five pairs arise from the dorsal surface of the aorta while the fifth or sixth pair depending on where the aorta terminates (fifth or sixth lumbar vertebral level) arises from the internal iliac arteries.

The lumbar arteries, after arising from the dorsal surface of the aorta, pass upward across the bodies of the lumbar vertebrae, reach the intertransverse spaces between the lumbar transverse processes and divide into dorsal and ventral branches. The dorsal branches are larger. They supply spinal branches to reinforce the ventral spinal artery and the muscular branches to supply the muscles and skin over the back (loin) region of the body trunk. The ventral branches run ventrally through the fascia and muscles of the abdominal walls and supply the muscles and skin of the walls of the abdomen.

Key Points

• There are several causes of abdominal pain.

• It is difficult to diagnose in animals, but behavioral changes may indicate abdominal pain.

• Evaluate and treat abdominal pain promptly to avoid life-threatening situations.

Introduction

Abdominal discomfort is typically acute (onset occurs suddenly), although it can also be persistent. It could be caused by inflammation of the abdominal wall or organs in the abdominal and pelvic cavities. Diagnosis is difficult due to the variety of etiologies involved. Patients with stomach pain demonstrate changes in behavior and posture. Treatment should be based on etiology and the underlying cause.

Animal’s response  to external stimuli is a behavior. Domestic animal behaviour and performance are correlated. Man’s intervention has led to huge modifications and modulations in animal behaviour patterns over ages but certain characters and normal behaviours of animals are needed to be expressed, otherwise may lead to abnormalities or performance loss. Animal freedoms also ensure certain basic freedoms to domesticated animals including freedom to express normal behaviour. With the developing concern over animal welfare among consumers, growers and animal activists, the need to ensure animal freedoms is call of the hour. Measuring animal welfare is a complex process which requires multidisciplinary approaches. There are four approaches to determine animal welfare viz, productivity, animal health and disease, physiology and behavior which are used individually or in combination.

Egg Formation Phenomenon

The chicken egg consists of a very small Reproductive cell or Germinal disc [orBlastoderm;which iscapable of developingintoanEmbryo, iffertilized by a Sperm]. This tiny cell is surrounded by :

• Yolk
= OVARYis responsible for its synthesis.

• Albumen, Shell membranes, Shell and Cuticle
= These are produced in the OVIDUCT.

[A] OVARY

Although there are two ovaries and two oviducts in the hen, but only the left ovary and left oviduct are functional [because, the right ones are atrophied during embryo development]. Before egg production, the ovary is a group of small follicles of different sizes containing ova.

Formation of Yolk

• The yolk is just a source of food material for the small Reproductive cell (Blastoderm).

• Major amounts of yolk material is produced in the liver and transported to ovarythrough blood.

• Two days afterthe formationof First yolk. Second yolkbegins to develop.

• It takes about ten days for a yolk to mature.

Absolute advantage : This is the simplest yardstick of economic performance. If one person, firm or country can produce more of something with the same amount of effort and resources, they have an absolute advantage over other producers. Being the best at something does not mean that doing that thing is the best way to use your scarce economic resources. The question of what to specialise in—and how to maximize the benefits from international trade—is best decided according to comparative advantage. Both absolute and comparative advantage may change significantly over time.

Access to Health Care : 1) The degree to which individuals are inhibited or facilitated in their ability to gain entry to and to receive care and services from the health care system. Factors influencing this ability include geographic, architectural, transportation, and financial considerations, among others. 2) Entry to the health care system is dependent on the wants, resources, and needs that individuals bring to the care-seeking process. Ability to obtain wanted or needed services may be influenced by many factors, including travel distance, waiting time, available financial resources, and availability of a regular source of care.

Acquisition cost : The purchase cost of a drug to an agency, person or institution.

Adaptive expectations : A theory of how people form their views about the future that assumes they do so using past trends and the errors in their own earlier predictions. Contrast with rational expectations.
