Mechanical damage in oil seeds like soya bean can be induced at any time during harvesting, handling, conditioning and sowing operations. There is relationship between moisture and mechanical damage. In general the low moisture containing seeds are more prone for mechanical damage than the high moisture containing seeds. In this experiment we look for this relationship by measuring seed quality parameters like germination and leakage (electrical conductivity).

Etiology

Avibacter paragallinarum Serotype A, B and C. Based on hemagglutinin serotyping, three serotypes (A, B and C) have been recognized.

Epizootiology

The chicken is the natural host although the disease has occasionally been diagnosed in pheasants. All ages of chicken are susceptible but birds up to 10 weeks are less vulnerable.

1. The chronic or healthy carrier birds serve as source of infection. Infection within farm occurs by contact with drinking water or feed contaminated by nasal discharge from sick/carrier chickens. To farms situated at a distance, infection is through air borne transmission.
2. The disease occurs more in cold and wet conditions. The more severe disease occurs when other respiratory diseases are prevalent at the farm.

Beta vulgaris 2n = 2x=18 is an important vegetable crop in Eastern and Central Europe and it belongs to family Chenopodiaceae. It is of lesser importance in Western Europe and USA where it is known as garden beet. The swollen roots are consumed as vegetable and salad. The other types which are non-horticultural forms are known as sugar beet, mangold and fodder beet.
Origin: Leaf beet is the earliest domesticated form. It is believed to be originated from Beta maritima known as sea beet which is indigenous to Southern Europe. 
Botany: Biennial producing enlarged hypocotyl (roots) and rossette of leaves in first year and flowers and seeds in second year.

5.1 Purpose

To employ a standard protocol to perform agarose gel electrophoresis.

5.2 Principle

Agarose gel electrophoresis is the most effective way of separating DNA fragments of varying sizes ranging from 100 bp to 25 kb. Migration rate of DNA molecule depends on various factors like 1) size of DNA molecule; 2) agarose concentration; 3) DNA conformation 4) voltage applied, 5) presence of ethidium bromide, 6) type of agarose and 7) electrophoresis buffer. After separation, the DNA molecules can be visualized under UV light.

The maximum water holding capacity is the amount of water, expressed as percentage on oven dry basis held by a soil when it is completely saturated with water. At this moisture content, all the pore spaces are completely filled with water.

A plum or gage is a stone fruit tree in the genus Prunus. The European plum is thought to have been discovered around two thousand years ago, originating in the area near the Caspian Sea, while Japanese plums actually originated in China. However, they derived their name from the country where much of their cultivation and development have occurred. Mature plum fruit may have a dusty-white coating that gives them a glaucous appearance and is easily rubbed off. This is an epicuticular wax coating and is known as “wax bloom”. Plum fruit tastes sweet and/or tart; the skin may be particularly tart. It is juicy and can be eaten fresh or used in jam-making or other recipes. Plum juice can be fermented into plum wine; when distilled, this produces a brandy known as Slivovitz or Rakia in Eastern Europe. Dried plums (or prunes) are also sweet and juicy and contain several antioxidants.

All the legume seeds and their byproducts are very rich in urease activity which may be responsible for an appreciable loss of urea nitrogen on long duration storage. Therefore it is necessary to estimate urease activity in legume seeds and their byproducts.

Reagents

    1.    Dimethyleaminobenzaldehyde solution (DMAB). Dissolve 16 g DMAB in 1 litre 95% ethyl alcohol and add 100 ml concentrated hydrochloric acid (Stable one month).
    2.    Pyrophosphate buffer. Dissolve 233 g Na4P2O7. 10H2O in approximately 980 ml distilled water. Add 3 ml of conc. Hcl and then dropwise further Hcl until the pH of the buffer is 7.7 to 7.8. Dilute to one litre.
    3.    Buffered urea solution. Dissolve 0.4 g urea in one litre pyrophosphate buffer (Stable one week).

Etiology

Ornithobacteriun rhinotracheale, bacteria, under phylum Cytophaga- Flavobacterium-Bacteroids. It is Gram negative non-motile, non-sporulating pleomorphic rod shaped bacteria. 18 serotypes Athrough R have been identified. Serotype A is prevalent in chicken and turkeys.

Disease occurrence

The disease is worldwide in distribution.

Turnip is the root vegetable cultivated in cooler season or temperate regions of the globe. Brassica rapa L 2n = 2x = 20 is formerly known as B. campastris subsp rapifera. Swede (B. napus var. napobrassica) is directly related to turnip.
Origin: It is originated in cooler part of Europe, presumably from biennial oilseed forms. It was known to Greeks and Romans at beginning of Christian era. It was introduced to Britain from France by Romans and into North America by the early European settlers in the 17th century.

India is the fastest-growing pet care market in the world and the pet population is of an estimate of 28-29 million, with dogs making up the bulk of pet ownership. The rising pet ownership has led to the growth of the pet care ecosystem comprising retail chains, pet nutrition pharmaceuticals, grooming, toys, clothing, diagnostics, and clinical practice. The pandemic of Covid-19 has a significant impact on the Indian economy; and the pet industry has seen a steep growth during the pandemic period. Isolation and anxiety during the lockdown led to many restorations to adopt furry companions. The veterinary graduate has a lot of opportunities, and it depends upon the individual as to what sector the student wants to pursue. Employment opportunities include diverse areas such as clinical practice, teaching, and research, regulatory medicines, public health, wildlife specialist, or lab animals. Depending upon the interest, one can start exploring options to work for the pet industry and join the Veterinary pet practice clinical.

Seed processing efficiency (SPE) is one of the important aspects in seed processing. It will help in measuring the potential of the shop floor. It will also help in standardizing activities like screens and improving physical purity. SPE will help to improve the quality of the seed material and help in utilizing the machines at their optimum capacity. SPE may vary among the different crops and even among the varieties.
 
To quantify SPE we need to pass the test sample (bulk-pre processed) through the target machine and enter the details in a processing register. To quantify the SPE we need to follow these mathematical formulae:

Objective: To get acquainted with classmates.

Description: This is the first lab activity and has been designed to make the students feel comfortable in their new surroundings. The aim is also to help them get acquainted with their classmates as they are still new to each other. This short fun activity will help them mingle and set the tone for upcoming activities.

Objective

The aim of this practical is to categorize insects based on their wing characteristics.

Introduction: Insect classification, as outlined by A.D. Imms (1957), divides Class Insecta or Hexapoda into two primary groups:

Group 1: Apterygota: These insects lack wings, and the absence of wings is considered primitive. Metamorphosis is minimal or absent. Adults typically possess one or more pairs of pregenital abdominal appendages. The mandible of adults usually articulates with the head capsule at a single point. This group comprises four orders:

1. Thysanura - Example: Silverfish

2. Diplura - Example: Japygids

3. Protura - Example: Telson tails or proturans

4. Collembola - Example: Springtails

Raspberries are grown for the fresh fruit market and for commercial processing. There are many species of raspberry but the name originally referred with the red fruit to the European species Rubus idaeus. The English name comes from an old English term “raspis”, which refers to the slightly hairy or “rasping” surface of the fruit. The raspberry can be of any colour from orange, pink, red, purple to black. Rubus albescens also known as Mysore raspberry is native to India. It is also called Snowpeaks, Ceylon or Hill raspberry.

Horse

In addition to the common articulations of vertebrae, the lumbar region of horse has two special articulations, the inter-transverse articulations and lumbosacral articulations.

The intertransverse articulations are bilateral joints formed between the transverse processes of the fourth and fifth and between the fifth and sixth lumbar vertebrae. The articular surfaces of these joints are the oval facets on the transverse processes of these vertebrae, the cranial ones being concave while the caudal ones the convex. These are synovial joints (diarthrodial). The capsule of the joint is reinforced ventrally.

The lumbosacral articulations are diarthrodial joints formed between the transverse processes of the sixth lumbar vertebra and the wings of the sacrum. These joints are similar to the intertransverse articulations.

The sacroiliac articulation of the pelvis is similar to that of ox. However, the sacrosciatic ligament is broader. Its lateral surface is related to middle gluteus, biceps femoris and semitendinosus muscles.
