Principle: To determine water in soluble solids, a known quantity of sample is boiled in water and the insoluble material is collected on a weighed filter paper. The insoluble mass is then washed with hot water and dried in oven.

ABSTRACT

Social primates appear to be knowledgeable about one another’s behaviour to different extents. But do they know as much about one another’s beliefs and intentions? Are they adept at recognizing the similarities and differences between their own and others’ states of mind?

It is characterized by irregular growth and development of hair follicles and associated glands.

6.1 Introduction
The majority of milk demand is urban, while production is restricted to rural areas in nearly all developed dairying countries. Consequently, milk must be collected and transported from production sites in the milk-shed areas to processing and distribution points in cities.
The common systems for collection (assembling) of milk are as follows.
1. Through a cooperative organisation. Established by collective or individual dairy societies. Producers are most advantageous when there are no intermediaries involved in profit labelling.
2. by contractors. Producers receive a diminished return.
3. By independent producers. Convenient for individuals who reside in close proximity to dairy processing facilities.
Note: The milk shed is the geographic region from which a city dairy obtains its fluid milk supply. India is currently contemplating the allocation of specific milk silos to individual dairies in order to facilitate their development.

Common name    :    English- Bur flower
        Hindi- Kadamb
        Odia- Kadamba

Family    :    Rubiaceae
 
Habit & Distribution
It is a tree (Fig. 66 a), seen growing widely in deep moist, alluvial sites and often in forests along river banks. It is widely distributed throughout India.

General Characters
The plant is a large straight deciduous tree that reaches to 45 m height. The leaves are large simple, elliptic-oblong, entire and 13-32 cm in length. Flowers are orange colored, small, in dense, globose heads that appear like solid, hairy orange balls. The fruits are small capsules, packed closely together. It bears flowers on May-July and fruits during August-October.

Leaf webber: Syngamia abruptalis :Pyralidae
 
Caterpillars feed extensively on tender foliage leaving veins alone and the growth of the plants are affected.

Leaf roller: Psara stullalis: Pyralidae

Larvae of these small moths are also leaf Webbers and rollers, and rolls the leaves and feed inside causing browning and drying of affected leaves. Inspect the crop for the pest incidence and remove the initial attacks systematically.

What new research is needed, what trials and how will the ultimate consumer and Industry benefit?
 
In Brazil, the sales of functional foods amounts to US $ 500 million per year representing about 1% of the total sale of the Brazilian food processing industry. According to a report the interests are mainly for dairy products, nutraceuticals and soy-based products. ABIA forecasts a substantial growth of 4.5-5% for this segment of the market (Stanton et al., 2001). In order to exert the health benefits beyond inherent basic nutrition, it is necessary that the activity of the probiotic culture should be maintained at very high levels during the shelf life of the product.

Purpose: The organic acids present in fruits and vegetables influence the flavour, colour, keeping quality and maturity. The maturity standards are determined by the acid and sugar ratio. The total acidity (citric acid) is determined by titrating the juice against standard alkali solution.

Equipments and chemicals: 10 ml., pipette, 25ml. Burette, small glass funnel, dropper, juice extractor, distilled water, 100ml. volumetric flask, burette stand, beaker, N/10 sodium hydroxide, filter paper, phenolphthalein indicator (one gram of phenolphthalein in 100ml. of 95% ethyl alcohol)

ABSTRACT

Male crickets use acoustic signals for long-distance mate attraction. Each cricket species has a unique calling song, used by females to recognize and localize conspecific males. Field cricket songs have wavelengths of several centimeters, which pose a difficult problem for these small animals in terms of localizing males, particularly in choruses. The chorus structure in terms of spacing, call intensity and timing, are important determinants both of the ability of males to synchronise their calls and of female mate-finding strategies.

Introduction

Veterinary Anatomy is regarded as the firm foundation and the knowledge gained in the subject is the basis for reasoning and helping with the diagnosis and treatment of animals. Teaching gross anatomy is highly regarded as being clinically relevant. The research on a wide range of species in Veterinary anatomy will be helping to be the understanding of their biology. The research conducted helps to understand the anatomy of domestic and wild animals and how this can be applied to diagnostic imaging and other disciplines of Veterinary Science. Hence teaching and research in anatomy provides foundation on which the knowledge of clinical practice and medicine is built. The research in Anatomy pave way for advanced research in other Veterinary Discipline.

TEACHING PERSPECTIVES

Anatomy education has entered newer and more innovative methods of teaching. “Vesalius” referred to as a founder of modern Anatomy struggled to make dissection of cadavers mandatory in 16th century and its significance is again being questioned today in search of substitutes. Hence use of alternatives to dissected specimens and multimedia teaching methodologies to teach anatomy and basic principles of Veterinary Medicine and Veterinary Surgery have gradually become more popular.

7.1 Introduction
Certain bacteria are present in milk that is extracted from the udder; they increase in quantity as it is processed further. The optimal temperature range for the proliferation of typical milk bacteria is 20 to 40 degrees Celsius. The formation of unpleasant flavours, increased acidity, and other factors always results in a decline in market quality following the proliferation of bacteria. Prompt chilling to a low temperature is one method of preserving milk. Milk jug Refrigerator: In order to preserve the purity of the milk received at the Dairy/Chilling Centre, it is chilled to 4°C using a milk chiller. Stainless-steel plates comprise the chiller. The process of chilling involves the circulation of chilled water from one side of the plates and milk from the other.
7.2 Methods
1. In can or can immersion method:
The milk is not only cooled, but it also remains cold, necessitating a significantly smaller mechanical refrigeration unit. This is achieved by transporting pails.
Benefits of a surface cooler
• Efficiently and swiftly transfer heat.
• Relatively affordable.
• Additionally, the milk is aerated, which enhances its flavour.

Common name    :    English- Shoo-fly plant
        Hindi- Popti

Family    :    Solanaceae
 
Habit & Distribution
The plant is a herb (Fig. 67 a), commonly found in fallow land, naturalized in waste places and near dwellings. It is distributed throughout India.

General Characters
It s an erect annual plant reaches up to 3-8 feet in height and are about half as wide. The leaves are large, alternate, reaching up to 1 feet long and somewhat resembles Datura leaves. Flowers are pale blue or blue purple with white centre. Fruits are berry, brown or yellow when matures, up to 2 cm in diameter. The plant flowers and bears fruits during October-February.

Sphingid larva: Dilephila nerii :Sphingidae

The large larvae cause severe damage to plants by feeding extensively on leaves, buds and flowers.They are very big and can easily be hand picked and killed or fed to poultry.

Abstract

The total Indian population is 1027.01 millions of which women account for 495.73 millions (2001 census). Women constitute about 48.27 percent of the population. The labour force participation of the women is 51.6 percent. In rural India, agricultural and allied activities employ as much as 89.5 percent of the female labour. Women have an active role and extensive involvement in livestock production, forest resource use and fishery processing. They contribute considerably to household income through farm and non-farm activities as well as through landless agricultural labours. They are deprived of exposure to knowledge and hardly participate in the process of decision-making. Female agricultural labourers are the poorest section of Indian society. Despite the women’s role in agriculture there has been a lack of adequate attention towards gender issue in the area of agriculture research.

Object: Estimation of water potential of plant tissue by Chardakov’s method.

Material required: Test tubes, sucrose or polyethylene glycol (PEG) 6000, methylene blue and dropper.

Principle: Concentration of the solution in which a plant tissue is immersed changes. If the solution is hypertonic (with lesser yw) the tissue loses water and the solution becomes dilute. If the solution is hypotonic (with higher yW) the tissue absorbs water and the Solution becomes concentrated. If the solution is isotonic (with yw equal to the tissue sap) the tissue neither loses nor absorbs water and the solution concentration does not change. Thus the yw of this solution gives the yw of the tissue.

ABSTRACT

Ethology, the biology of behaviour has been a fascinating area of biological investigations during past few decades. In recent past the information gathered by reputed ethologists on social behaviour of insects, fishes, birds and human beings are very helpful in the application of these principles for the welfare of the humanity as well as for the environmental sustainability. Ethology differs from the study of Animal Behavior, in that animal behaviorists generally are interested in learned behaviors while ethologists concentrate on innate behaviors.
