Ensuring the health and well-being of your pet dog is a top priority for every responsible pet owner. Understanding common diseases that affect dogs and taking preventive measures can significantly improve their quality of life and longevity. Here’s an overview of some prevalent canine diseases and how to prevent them:

1. Parvovirus (Parvo)

• Parvovirus is a highly contagious viral disease that affects dogs, especially puppies.

• Symptoms include severe vomiting, diarrhea (often bloody), lethargy, and dehydration.

• Prevention: Vaccination is the most effective way to prevent parvovirus. Puppies should receive a series of vaccinations starting at 6-8 weeks of age, with boosters every few weeks until they are 16-20 weeks old.

Many families who have had the pleasure of raising rabbits consider them to be valuable members of their family. Unfortunately, rabbits are susceptible to a wide range of issues and illnesses, much like other pets. Upper respiratory tract infections (snuffles), internal and external parasites, dental disease, gastrointestinal (GI) stasis, uterine issues (cancer or infections), and pododermatitis (foot sores or sore hocks) are common illnesses that affect pet rabbits. Rabbits are incredibly prolific creatures with a vast potential for procreation. 

1.1. Introduction

A typical dairy farm consist of different classes of dairy animals like calf, heifer, breeding heifer, pregnant, milch and dry animals and bull. The systems of management for the different classes are not same. They need some routine as well as periodical farm practices, some of which are common for all categories of animals (i.e., identification, dehorning, grooming etc.), while some categories need special farm operations (e.g., castration in males, milking etc.). Also there is need of routine disinfection of animal sheds and farm premises to prevent and control occurrence of diseases and maintaining the animals healthy. Further for proper execution of all these operations there is need of keeping farm records.  Keeping in view the above points, this section deals with some important farm management practices.

Anti–nutritional factors: Detoxification of undesirable components is very important, because some feeds may contain toxic substances, the excess consumption of which may cause decreased nutritive value of the feeds or may injure some vital organs or even cause death. 
Points to ponder
• Anti – nutrients present in the diet, either by themselves or their metabolic products arising in the system.
• Plants evolved these compounds as defensive mechanism against insects, parasites, bacteria and fungi.
• Feeds high in anti – nutrients: Lectins = legumes, cereal, grains, seeds, nuts, fruits, vegetables. Oxalates = spinach, swiss chard, sorrel, beat greens, beet root, rhubarb, nuts, legumes, cereal grains, sweet potatoes, potatoes. Phytate [IP6] = legumes, cereal grains, pseudo – cereals (amaranth, quinoa, millet), nuts, seeds.
• Anti – nutrient in wheat: Phytate being the most important among all, reduces the bio – availability of Iron and Zinc. There could be protease inhibitor, tannin, lectin, alkaloid, oxalate too.
• Main anti – nutrients in edible forage and fodders are: tannin, saponins, phytic acid, gossypol, lectin, amylase inhibitor, goitrogen, protease inhibitor.
• Removal of anti – nutrients: heating, boiling, soaking, spouting, fermentation. By combining different methods, many anti – nutrients can be degraded completely.

1. Collection of arthropods

a. Collection of arthropods from the host’s body: The collection of arthropods from the host’s body involves various techniques tailored to different species and circumstances. For instance, the extraction of small ectoparasites such as lice, fleas, and wingless keds typically employs usage of forceps with pointed tips for precision. In poultry, a method of brushing against the grain of feathers enables dislodgement of ectoparasites, which are then collected on a black surface for examination. A highly effective strategy for harvesting ectoparasites from small or deceased hosts, such as poultry, involves sealing the carcasses within a polyethylene bag. This confinement prompts ectoparasites to detach from the host and accumulate within the bag, facilitating subsequent collection using a brush. The retrieval of ticks to prevent the rupture of their mouthparts is achieved by straightening the tick forward and pulling backwards before extraction. These ticks are further placed in a tube sealed with a ventilated stopper or a gauze covered with cotton wool plug. The tubes ought to include paper for the ticks to cling onto, along with a labelled piece of paper. These tubes are stored in a cool and humid container for transportation to the laboratory. This container should be well-insulated and equipped with ice blocks or freezer packs as well as damp pads to sustain elevated humidity levels. It’s crucial to ensure that the ticks do not directly touch the ice. A sizable thermos flask can be utilized for this purpose. Mange mites, on the other hand, are obtained by conducting deep skin scrapings from the periphery of affected lesions, enabling the collection of specimens for analysis.

Common feeds and fodders: An edible material which is ingested, digested, absorbed, assimilated by the animals for their benefit, is known as feed. As per the National Research Council, Dry forages and roughages are cut and cured. These are bulky feeds with low digestibility. Crude fibre is > 18 % and TDN is < than 60 % because of high cell wall content. Some of the common feed stuffs are: dry grass (hay), wheat straw, paddy straw, oat straw etcetera. Stovers [aerial part without ears and husk (maize) or aerial parts without heads (sorghum). Hulls and shells too. Pasture range plants, tree leaves and forages are either harvested or without harvesting (fresh) are also very good for feeding, for example: pasture grass, range plants, tree leaves, green forages. Concentrates have < than 18 % crude fibre and > than 60 % TDN. Feeds rich in protein (plant origin) are: Cotton seeds / cakes, Mustard cake, Groundnut cake. Whereas animal origin protein sources are: Skim milk, Fish meal, Blood meal. Feeds rich in carbohydrates (energy) in grains are: Maize, Oat, Barley. Whereas grain by – products are: Wheat bran, Rice bran, Gram husk, Pulse chuni.
Points to ponder
• Animals are sometimes said “to feed” or to eat, therefore to mean = “food for animal”. The old English root is fedan = “nourish, sustain or foster”.
• Fodders are harvested and taken to animals; whereas, Forages are browsed on by animals, while still on the land.
• Feed manufacturing refers to the process of producing animal feed from raw agricultural products; whereas, Fodder produced by manufacturing is formulated to meet specific animal nutritionrequirements for (i) different species of animals, (ii) different life stages. The idea is: to transfer the seed energy and the plant’s energy to the animal.

Roughage contains > than 18 % crude fibre and < than 60% Total Digestible Nutrients (T.D.N.). Leguminous fodders contain more Digestible Crude Protein (D.C.P.). Some common dry legumes are: Pea straw, Arhar straw, Lucerne hay. And some common green legumes are: Berseem (clover), Cow pea, Lucerne (alfa alfa). Non – leguminous fodders contain less D.C.P. Some common dry non – legumes are: Wheat straw, Paddy straw, Oat hay, Grass hay. Whereas, some common green legumes are: Sorghum, Maize, Oat, Napier.

The response of any living cell to a xenobiotic (including antibacterial agent) is significantly affected by the prevailing local environmental conditions. In case of bacterial infection, it may include the presence of other microbes, no matter commensal or pathogenic, or biochemical alterations at that particular site of bacterial infection in host. All these host and bacterial factors play a critical role in the evolutionary responses of bacteria but usually go unconsidered while determining the microbial sensitivity to a particular antibiotic in a clinical setting. These also include the direct and indirect interspecies interactions that can affect the responses of individual bacterial species and surviving microbial communities to a particular antibiotic therapy. These interactions may significantly alter the qualitative and quantitative responses, potential phenotypic changes and the final trajectory of evolution of antimicrobial resistance. Due acknowledgement and plausible interpretation to these interactions may help to reduce the upsurge in AMR and its associated morbidity and fatality and pave path to more proficient clinical success.

The factors participating in drug- microbe interaction can be classified into two broad groups: host factors and microbial factors. The environmental milieu of the interaction is chiefly regulated by the gut microbiota with stressors causing deflections. The gastrointestinal bacteria amend host mental and physiological cadence via microbial metabolites such as butyrate, polyphenolic antioxidants, vitamins, and amines, affecting the overall ready perception and active rebuke to a stimulus. Lifestyle stressors such as fluctuating sleep and erratic eating patterns (western diet) disturb the host circadian system along with the gut microbiome. The overall impact is impaired detoxification (decreased conjugation of bile acids or increased production of hydrogen sulphide), substrate oxidation and energy regulation (reduced butyrate production) in the host affecting the overall health and productivity.

a) Lead b) Nitrate

c) Arsenic d) Cadmium

Animals contract poisoning due to a variety of toxic chemicals (inorganic and farm chemicals), phytotoxins, mycotoxins, and zootoxins, which is often
fatal. Toxic chemicals and poisonous plants represent a tremendous economic impact. However, more often the poisoning episodes go undiagnosed. In
general, poisoning is suspected when number of previously healthy animals show same symptoms and severity of illness at the same time and the same
lesions at necropsy.

CONTRACEPTION DUE TO MISALLIANCE AND TERMINATION OF PREGNANCY IN BITCHES

It is obvious that breeders maintain varieties of breeds but mismating do occur within their own premises and sometimes by unwarranted stray animal.

Misalliance complicates too many other problems.

Incidence of mismating is 15 to 20 percent in canine breeding.

Activation : The process of causing a substance to become artificially radioactive by subjecting it to bombardment by neutrons or other particles.

Activation Analysis : Any analytical procedure permitting the detection and measurement of trace quantities of elements following their exposure to a flux of neutrons.

Activity :  The strength of a radioactive source. In absolute units, it relates to the number of radioactive atoms decaying per unit of time. It is also a synonym for radioactivity. Absolute activity is usually expressed in curies or millicuries.

Alpha Particle : A particle which is identical to the helium nucleus, consisting of two protons and two neutrons. It carries a positive charge of 2.

Alpha Rays: A stream of helium nuclei. The helium nucleus has a mass number of 4 and an atomic number of 2. If consists of two protons and two neutrons.

Cellular stains are the colouring compounds used to impart different colours to varied type of cellular components and help in the demonstration of different micro-organisms such as bacteria, viral inclusions, fungal hyphae etc. The staining techniques enhance the contrast of tissue sections at microscopic level including histological, histopathological and cytological grounds. Before applying the special staining techniques on tissue sections few points which should be taken care include:
• Use of appropriate volume, concentration and type of fixative for preservation of tissue samples.
• Use of fixative with better compatibility as per the nature of tissues to be preserved.
• The tissue sections collected should not be very thick (5 mm approximately).
• Staining solutions should be immediately prepared where so ever required.
• Tissues must be sectioned with an ideal thickness between 4-6 microns.
Different types of stains routinely used to demonstrate varied type of cellular components and microorganisms:
Grocott’s Methenamine Silver (GMS) Staining Method
The fungal hyphae can be better demonstrated with Grocott’s Methenamine Silver stain (GMS). The basis for colouration of fungus is entirely based upon the oxidation of chromic acid forming aldehyde from the cell wall constituents of fungus and thereby reducing the silver-hexamine complex. The silverhexamine complex leads to the reduction of nascent Ag ions and leading the blackening of fungus in tissue sections.

Objectives
• To understand the meaning and importance of communication.
• To explore the basic components and process of communication.
• To identify the different types and forms of communication.
• To recognize barriers to effective communication and strategies to overcome them.
• To develop an appreciation for the role of communication in personal and professional contexts.
Meaning and Importance of Communication
Communication is the process of exchanging information, ideas, emotions, and messages between individuals or groups. It is a fundamental aspect of human interaction and plays a vital role in personal, social, and professional contexts. Effective communication enables understanding, fosters relationships, and facilitates decision-making.

Introduction
Communication is an essential component of any organization’s functioning. The ability to convey information accurately, succinctly, and in a timely manner affects every aspect of business, from operations to strategic decision-making. Efficient and effective communication is fundamental to achieving organizational objectives, enhancing productivity, and fostering collaboration. While “efficiency” refers to the speed and resourcefulness of communication, “effectiveness” focuses on the accuracy, clarity, and impact of the message conveyed.
Defining Communication Efficiency and Effectiveness
• Communication Efficiency: Efficiency in communication is about minimizing the time, energy, and resources needed to convey a message. It involves optimizing communication channels, minimizing redundancies, and streamlining processes to ensure that information is delivered as swiftly and resourcefully as possible.
• Communication Effectiveness: Communication is effective when the message is clearly understood, achieves its intended impact, and facilitates desired actions or outcomes. This involves ensuring clarity, relevance, and accuracy in messaging, as well as selecting appropriate channels and formats to engage the target audience.
Theories of Communication in Organizations
This section will provide an overview of several foundational theories of communication that inform both efficiency and effectiveness.
1. Shannon-Weaver Model (1949): Introduced the concept of the “noise” affecting communication efficiency and the importance of feedback loops.

Objectives
• Understand the concept of communication gap.
• Identify the reasons behind communication gaps in personal, professional, and organizational settings.
• Explore the effects of communication gaps on relationships and productivity.
• Develop strategies to overcome communication gaps effectively.
Communication Gap
A communication gap occurs when there is a breakdown in the communication process, leading to misunderstandings, incomplete information transfer, or misinterpretation of messages. It can happen between individuals, groups, or organizations, and has significant impacts on relationships, productivity, and decision-making.
Reasons for Communication Gaps
Several factors contribute to communication gaps. These reasons can be categorized into three broad areas: individual, organizational, and technological.

Models Definitions

In social science research a model is a tentative description of what a social process, say the communication process or a system might be like. It is atool of explanation and analyses, very often in a diagrammatic form, to show how the various elements of a situation being studied relate to each other.

What is a Model?

Aristotle, Shannon and Weaver, Schramm, Berlo, Westly and Maclean, Leagan, Rogers and Shoemaker, Littererls model and Dance’s Helical Model-Elements of communication-communication barriers

Introduction

Models are symbolic representation of structures objects or operation. They can be used to show the size shape or relationship of various parts or components of an object or process. It helps to explain the working of a system. A model helps to get a whole idea of the system.

Model help to illustrate, predict and explain the concept

They can be structural or process oriented

Make us to understand the way how to interpret the process

Communication word comes from Latin ‘Communis’ - Common

Communication: The communication is the process of human interaction in

which one person communicates a message/idea to another person.

Diffusion: It is the process by which an innovation/new idea/new technique

spreads.

According to Rogers (1983) ‘Communication is the process by which the

message is transmitted from the source to the receiver’.

Function of communication

1. Informative

2. Instructive/Command

3. Influence/Persuasive

4. Integrative

Communicator: Person who starts the process of communication OR he is the

sender of message

Message: It is the information the communicator wishes his audience to

receive, understand and act upon

Encoding: It is a process of interpreting the message

Decoding: It is a process of receiving the message
