Principle

A simple and rapid enzymatic method for the quantitative estimation of total cis-methylene- interrupted polyenoic acids has been devised. Linoleic, linolenic and arachidonic acids, the more common acids of this group were used to calibrate the method. The potassium salts of the fatty acids are oxidised by atmospheric oxygen in the presence of the enzyme lipo-oxidase, and the absorption of the conjugated diene hydroperoxide is measured at 234 mµ. As little as 5 µg of linoleic acid can be quantitatively measured with good accuracy and precision. The total content of polyunsaturated fatty acids containing the cismethylene-interrupted diene structure of fats, oils, hydrogenated oils, fatty acids, esters blood plasma, microorganisms and plant seeds has been measured directly by this method.

The diseases that occur during the first one month of life are termed as diseases of neonates. During this period, the animal requires special attention to reduce
mortality rate. The clinical examinations that are applied to adult animals are being used for the examination of newborns.

Gravimetric Method — Principle

Total lipids in plasma consist of neutral fats, phospholipids, chloesterol esters and free cholesterol. Minor components include non-esterified fatty acids (NEFA), phosphatides and sphingo myelin. Total lipids in serum or plasma are extracted using ethyl alcohol and petroleum  ether, separated and weighed after drying at 105ºC.

Procedure
Pipette 5 ml serum in a separating funnel, add 5 ml ethyl alcohol and 12.5 ml pertroleum ether. Shake the contents of funnel two times for 3 min. atleast. Keep the contents of funnel as such for one hour. Transfer the contents of funnel in the moisture cup, dry and weigh. Calculate the result by difference method using the following formula.

Introduction

(Titrimetric Method of  Cherry and crandall, 1932 Modified by Tietz and Fiereck, 1966).

In 1932, Cherry and Crandall employed olive oil as the substrate for pancreatic and serum lipase (LPS. Triacylglycerol lipase) determinations. In subsequent years this method was improved (Tietz et al., 1959; Tietz and Fereck, 1966: Tietz. 1972), reducing the original 24 h, period to 6 h and finally to 3 h.

Principle
This procedure is based on the hydrolysis of triglycerides in olive oil into fatty acids, diglycerides and to some small extent into monoglycerides and glycerol.

Peripheral nerves

The peripheral nervous system (PNS) is the part of the nervous system that lies outside the brain and spinal cord. It includes cranial nerves, spinal nerves and their roots and branches, peripheral nerves and neuromuscular junctions. In the peripheral nervous system, bundles of nerve fibres or axons conduct information to and from the central nervous system. The primary role of the peripheral nervous system is to connect the central nervous system to the bones, muscles and skin of the body trunk and the limbs and the organs to allow the complex movements and behaviour.

The peripheral nervous system is divided into the somatic nervous system and the autonomic (visceral) nervous system.

The somatic nervous system is associated with skeletal muscle voluntary control of body movents. It consists of afferent and efferent nerves. Afferent nerves are concerned with relaying sensation from the body to the central nervous system. The efferent nerves are responsible for sending out commands from central nervous system to the body, stimulating muscle contraction. This system is made up of nerves that connect to the skin, sensory organs and all skeletal muscles.

The autonomic nervous system is the part of peripheral nervous system that controls the visceral functions which occur below the level of consciousness. It consists of two divisions, the sympathetic nervous system and the parasympathetic nervous system.

5.1 Kinds of Soil Water

The following re the three main classes of soil water:

(i)  Hygroscopic water. Water held tightly to the surface of soil particles by adsorption forces.

(ii) Capillary water. Water held by forces of surface tension and continuous films around soil particles and in the capillary spaces.

(iii) Gravitational water. Water that moves freely in response to gravity and drains out of the soil.

Horse

Articulations of bones of skull

Most of the joints of the bones of skull are sutures similar to those in ox. However, in the adult horse many of the sutures are effaced. The ossification of the cartilage between the basilar part of the occipital and the sphenoid occurs quite earlier. The fusion of the mandibular symphysis takes place at about second to third month after birth. The temporomandibular articulation has an additional ligament which consists of elastic tissue. It connects the post-glenoid process to the caudal border of the ramys of the mandible.

Hyoidean articulations

In the hyoidean articulations, there is only one intercornual articulation in horse instead of the proximal and distal cornual articulations appearing in the ox. The middle cornu is generally lodged in the articulation between the great and small cornu.

(Method of Cocimano and Leng, 1966; Conrad, 1972; Varady & Harmeyer, 1972)
Hypothesis

The validity of measuring urea kinetics using a single dose of ¹⁴C-urea and using urinary excretion as a sampling system is based on specific assumption:

    1.    There is a rapid equilibration of ¹⁴C-urea with the endogenous urea pool following infusion. This pool is conceived to be a measure of all body compartments permeable to urea and in equilibrium with the plasma urea pool. 

    2.    Experimental animals are metabolically maintained in a steady state during the test period and metabolic breakdown of urea is random.

    3.    Specific radioactivity for urinary urea is proportional to the dilution of replenishment and simultaneous depletion rate of the urea pool.

    4.    That the metabolic parameters of urea are correctly measured.

This chapter explains how representative soil samples should be collected, labelled, transported and prepared for analysis. It identifies essential sampling equipment, including spades, khurpis, augers, trays, sampling bags, markers and polythene sheets. The recommended procedure involves dividing land into uniform sampling units, collecting soil from several well-distributed locations and combining these portions into a composite sample. The chapter describes V-shaped sampling cuts, suitable sampling depths and sample reduction through quartering. It also lists the field information that should accompany each sample. Procedures for air-drying, grinding, sieving and mixing samples are presented, together with precautions for avoiding unusual areas and contamination.

Phenotype is the product of genotype and environment. In presence of genotype x environment interaction (differential performance of genotypes over the environments), phenotype is the product of genotype, environment and genotype x environment interaction. A stable genotype is one which interacts less with the environment or shows a minimum of g x e interaction. When g x e interaction is significant, one must investigate the specific types of g x e interactions such as genotype x location, genotype x year and genotype x location x year interactions by growing selected genotypes over multiple locations and years. Normally, the genotypes are evaluated for three years. A typical analysis of variance for g x e interaction is given in Table 7.1 (Allard, 1960).

Articulations of thoracic vertebrae

These are (1) Intercentral articulations which are amphiarthroses formed between the bodies of the adjacent vertebrae and (2) Inter neural articulations which are diarthroses formed between the articular processes of the vertebrae. These articulations are similar to the articulations described for typical vertebrae of the cervical region. The only difference is that the supraspinous ligament in the thoracic part of vertebral column is single as against two parts the funicular and lamellar parts of the cervical part of this ligament. The supra spinous ligament in the thoracic part is the backward continuation of the funicular division of its cervical part which extends medially behind from the occipital eminence , passes through the cervical region as nuchal ligament and continues behind over the summits of the spinous processes of the thoracic and lumbar vertebrae and finally terminates on the sacrum.

It is rich in iron and Vit –C and native of tropical Asia particularly eastern India and Southern China (Sheshadri 1986 Mini Raja et al., 1993).
