A variety produced by crossing inter se a number of genotypes selected for good general combining ability in all hybrid combinations with subsequent maintenance of the variety by open-pollination. According to Hayes and Garber (1919), the synthetic production of an improved variety by inbreeding and cross-breeding seems a reasonable plan. Synthetic cultivar is a commercial entity and a combination of number of inbred lines, sibbed lines, clones or other populations of cross-pollinated crops. The features of the components are as follows:

1. They will have been tested for their combining ability.
2. They will be preserved for future syntheses of the synthetic variety.
3. The component lines will be combined in a manner so as to allow random mating.

Synthetic varieties are normally used in cross-pollinated crops in those situations where hybrid development and organized seed production are in the preliminary stages. Inbred lines are common components of synthetics because they are easy to maintain and can be used again and again as per requirement of reconstituting the synthetics. When selfing is not possible, sibbing may be used. In case of perennials, clones are used as components. Combining ability of the component lines is determined in different ways. General combining ability is desired more than the specific combining ability because there are several components to a synthetic variety and each is required to combine well with the rest other lines. Random crossing of components of a synthetic variety is assumed and each line should contribute the same amount of seed to the next generation. Because a synthetic variety is a mixture of many genotypes, it might change under selection pressure during multiplication.

4. 1. Origin and distribution

• Native to Egypt, Syria, Middle East and stretching east to India.

• In India, cumin is mainly cultivated in Western Indian states like Rajasthan and Gujarat.

4.2. Economic importance

• Important spice used in Indian kitchens for flavoring various food preparations.

• The flavor is due to chief constituent cuminol (Cuminaldehyde)

• Volatile oil is up to 2.5-3.5 %.

• Used in various ayurvedic medicines especially for the conditions like obesity, stomach pain and dyspesia.

• Many Latino, Vietnamese, United States and Thai foods recipes have cumin and many chilli recipe includes cumin.

• In India, cumin is a traditional ingredient not only curry, but also kormas, masalas, soups and other recipes.

• Used in some cheeses like Leyden cheese as well as some French breads.

The wall of the thorax and its contents (the viscera) are supplied by the following branches of the thoracic aorta.

Brachiocephalic trunk

The brachiocephalic trunk (Fig. 3-4 A) is a large vessel distributing arterial branches to the head, neck, thoracic limbs (fore limbs) and the cranial part of thorax especially to the region of the withers, thoracic floor and parts of the cranial third of the lateral thoracic wall. It arises from the convexity of the aortic arch between the right auricle and pulmonary artery within the pericardium. It is directed cranially and dorsally in the cranial mediastinum ventral to the trachea. It is partly covered on the right side by the cranial vena cava and on the left it is crossed by the vagus nerve. The recurrent laryngeal nerve runs between it and the trachea. It gives off the left subclavian artery opposite the second intercostal space or the third rib and the right subclavian artery opposite the first rib and then continues cranially as the common bicarotid trunk.

The subclavian arteries entirely furnish blood supply to the thoracic limbs. Except for different (separate) origins and the left artery being longer than the right artery, the right and left subclavian arteries are identical in their course and distribution. A short portion of each artery is within the thoracic cavity and is called as intrathoracic course. Each of these arteries leave the thorax by encircling and crossing the cranial border of the first rib below the insertion of the scalinus ventralis muscle and above the brachial vein. The intrathoracic branches of the subclavian arteries are the costocervical, caudal cervical and internal thoracic arteries.

The lymphatics of the thoracic region are comprised of large number of lymph nodes which are arranged in different groups like the aortic, sternal, mediastinal and bronchial. The efferent ducts from these lymph nodes ultimately join the thoracic duct which carries lymph from all over the body except the head neck and fore limb to open in the cranial venacava.

Thoracic aortic and sternal lymph nodes

The lymphatics of the thoracic and sternal region is comprised of thoracic aortic, intercostal, cranial and caudal sternal, and the xiphoid lymph nodes and the thoracic duct which conducts the lymph collected from most of the parts of the body except the head, neck and fore limbs.

The thoracic aortic lymph nodes are located along the dorsolateral border of the aorta, ventral to the sympathetic trunk. The afferents for these lymph nodes are received from the muscles of thoracic wall, diaphragm, pleural and pericardial sacs and the intercostal lymph nodes. The efferents from the thoracic aortic lymph nodes are connected to the thoracic duct either directly or through other lymph nodes of the thoracic cavity.

Pepsin Digestibility of Food
Principle

Solvent extracted samples are digested for 16 hour with warm acid solution of pepsin under constant agitation. Insoluble residue is centrifuged, dried and weighed and analysed for protein ; or filtered, washed and analysed for protein.

Apparatus
    1.    Centrifuge : Capable of at least 1750 rpm with conical bottom tubes of 150 ml capacity. If necessary, solution may be centrifuged in 50 ml tubes.
    2.    Agitator : or water bath with shaking device and having temperature controlling unit.
    3.    Glass fiber filter paper.

Arteries of thorax

Horse

The bronchial and oesophageal arteries in horse have a common trunk of origin as broncho-oesophageal artery. It arises from the convexity of aortic arch, passes ventrally and caudally on the right side of the aorta and divides into bronchial and oesophageal arteries. The oesophageal artery passes caudally in the caudal mediastinum along the dorsal face of oesophagus and supplies branches to oesophagus, caudal mediastinal lymph nodes and pleura and anastomoses with the pleuro-oesophageal branch of the gastric artery.

The intercostal arteries are eighteen pairs in number. The first pair arises from the superior artery, the next three pairs come from subcostal artery and the remaining four arise from the thoracic aorta.

The phrenic arteries are not variable in origin as in the ox. They are small and are two to three in number. They arise on the ventral face of the aorta while it passes through the hiatus aorticus and enter the crura of the diaphragm.

The rest of the arterial branches of thorax in horse are similar to those in ox.

PEG Estimation
Introduction
Polyethylene glycol (PEG) is used as a marker for the estimation of rumen water volume and ruminant digestion studies (Hyden and Ekman, 1953). Long back, Hyden (1955) developed a turbidimetric method which is described below :

Principle
When trichloroacetic acid is added to a solution of PEG, a turbidity is produced, which can be measured photo-electrically. The intensity of the cloud, which consists of finely divided oily droplets, is increased in the presence of barium ions. Protein and sulphate must be completely removed from the sample before the addition of the trichloroacetic acid reagent. Sulphate is precipitated with barium chloride and the proteins are removed essentially according to Samogyi (1945). The method has been developed for determination of PEG in ruminal and abomasal fluids, but it has been tried with other biological materials too.

8.1. Origin and distribution

• Originated in South and South East Asia.

• Cultivated mostly from Pakistan to Papua New Guinea.

8.2. Economic importance

• In India and Sri Lanka, sheaf of betel leaves are traditionally offered as a mark of respect and auspicious beginnings like greeting elders at wedding ceremonies, celebrating the New Year, and offering payment to Ayurvedic Physicians and Astrologers (To whom money and/or areca nut placed on top of the sheaf of leaves are offered in thanks for blessings).

• Consumed in Asia as betel quid or paan with arecanut and/or tobacco.

• Used in cooking usually raw for its peppery taste.

• Medicinal use over a 300 years history in China.

Sacroiliac articulation

The sacroiliac articulation (Fig. 4-2 A) is a synovial (diorthroidal) joint formed between the articular surface on the wing of the sacrum and pelvic surface of the proximal extremity of the ilium. The articular area of the wing of the sacrum has a rough eminence while that of the ilium has a reciprocal rough depression. Both the articular areas are covered by a thin layer of cartilage. The joint cavity is a thin like a cleft and is crossed by fibrous bands.

The joint capsule is closely fitting around the margins of the articular surfaces. The joint capsule is reinforced by the ventral sacroiliac ligament which surrounds the joint. The dorsal part of this ligament is quite strong and it occupies the angle between the ilium and wing of the sacrum. The movements are inappreciable at this joint.

The Total Horticulture production of the country is estimated to be an impressive level of 314.87 Million Tonnes during 2018–19.

Production of fruits is estimated to be about 97.38 million tonnes during 2018–2019.

Production of vegetables is estimated to be about 187.36 million tonnes during 2018–2019.

Production of spices is estimated to be about 8.61 million tonnes during 2018–2019.

Plantation crops are another potential sector with lot of opportunities for employment generation, foreign exchange earnings and overall supporting livelihood sustenance of mankind at large.

In short and sweet horticulture supplies quality food for health and mind, more calories per unit area, develops better resources and yields higher returns per unit area.

It also enhances land value and creates better purchasing power for those who are engaged in this industry. Therefore, horticulture is important for health, wealth, hygiene and happiness.

Similar to forest trees these horticultural trees will maintain the ecosphere. They help in transforming the micro climate.

It provides shelter to birds, reptiles and other micro organisms and add to the geo–ecological diversity on the land.

Horse

The kidneys of horse slightly differ in form and size than those of ox. The outer surfaces of kidneys of horse are smooth and plane as against lobulated kidneys of ox. The right kidney is like the heart of the plying cards while left kidney is bean shaped. The right kidney is placed under the vertebral ends of the last two ribs and first lumbar transverse process. The left kidney is situated under the last rib and the first two or three lumbar transverse processes. The hilus of both the kidneys is at about the middle of the medial border of the respective kidneys. The cranial extremity of the right kidney is thicker while the caudal extremity of the left kidney is wider and thicker. The hilus of the kidneys lead into the renal sinus in the interior for the lodgment of the renal pelvis which is the dilated origin of the ureter. The inner central part of the medulla forms a concave ridge called the renal crest. It presents numerous openings through which the large ducts open into the renal pelvis. This part is called the area cribrosa.

The ureter of the horse kidney begins at the renal pelvis and is about 70 cm in length and 6 to 8 mm in diameter.

The urinary bladder of horse is shorter but wider than that of the ox. Its capacity is about 2.8 to 3.8 liters. The rest of the features are same as those of ox.
