Goat is a versatile animal having short generation interval with lower investment cost and higher prolificacy. The present study was carried out at Goat farm, LPM, GBPUAT, Pantnagar. During the entire study the fresh milk samples of Pantja goats were taken according to lactation order and stage viz., 1st (Upto 30 days), 2nd (31 to 60 days) and 3rd (above 61 days) stage of lactation were analyzed for physico-chemical properties. The values of milk composition were significantly affected by lactation order and stage of lactation and their interaction. The color of Pantja goat milk was perfectly white in all the lactation order and lactation stages. The specific gravity and boiling point of milk increased significantly from 1st to 3rd lactation order and with advancement of lactation stage. The milk composition; fat, protein, total solids, solids not fat, total ash and chemical properties viz. titratable acidity of milk was increased significantly in advanced lactation order and stage of lactation except, pH, water and carbohydrate which showed a declining trend.

Withania somnifera (L.) Dunal (Fam. Solanaceae) commonly known as Ashwagandha has been used in traditional Indian medicine system from ancient times. Roots of the plant are being used in the preparation of many Ayurvedic medicines for treatment of many diseases. Many compounds have been reported and isolated from the roots, which mainly consists of withanolides, (steroidal lactones). In present study, the roots of 25 diverse W. somnifera genotypes were collected and evaluated for morphological parameters, such as root length, root diameter and dry root yield. Total alkaloids, crude fibers and starch content were also estimated from the dried roots of these accessions. TLC and HPLC revealed the presence of withanolide A in the methanolic extract of roots from diverse genotypes. Quantification through reverse-phase HPLC revealed varied concentrations of withanolide A in different genotypes grown under field conditions. Accumulation of withanolide A was reported highest in the genotype UWS-59 makes this genotype superior for medicinal use. [ABSTRACT FROM AUTHOR]
