Chaudhary Sarwan Kumar Himachal Pradesh Agriculture University, Palampur

Himachal Pradesh Krishi Vishvavidyalaya (renamed as Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya in June, 2001) was established on 1st November, 1978.The College of Agriculture (established in May, 1966) formed the nucleus of the new farm University. It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country. Today, the State has earned its name for hill agricultural diversification and the farming community has imposed its faith in the University.

    USE OF GINGER POWDER (Zingiber officinalis) AND ORGANIC ACIDS AS ALTERNATIVES TO ANTIBIOTIC GROWTH PROMOTERS IN BROILER PRODUCTION
    (CSKHPKV, Palampur, 2011-06-30) Goswamy, Varsha; Rani, Daisy
    A study using 330 day-old Vancobb broilers was conducted to determine the effects of antibiotic, ginger powder (Zingiber officinalis) and organic acids on biological performance, fecal quality, weight of liver, gall bladder, lymphoid organs and abdominal fat, meat quality, pH of small and large intestinal contents, morphometry of small intestines and economics of broiler production. The broilers were randomly allocated to 11 treatments including a negative control (NC; basal diet only) and a positive control (PC; basal diet+Zinc bacitracin). There were 30 chicks in each treatment with three replicates of 10 chicks per treatment. The broilers were offered diets supplemented with ginger powder (G), acetic acid (AA), propionic acid (PA), fumaric acid (FA) at 0.5, 0.1, 0.15 and 0.5 per cent, respectively and their combinations i.e. ginger powder + acetic acid (GA), ginger powder + propionic acid (GP), ginger powder + fumaric acid (GF), acetic acid + propionic acid + fumaric acid (APF), and ginger powder + the three acids (GAPF) at the same dose rates. The feed intake, weight at 4th week, weight at 6th week and mortality were recorded. Five birds were slaughtered out of each treatment, after the end of 6 weeks of age and, dressed weight, weight of liver, gall bladder, spleen, thymus, bursa and abdominal fat were recorded. The samples of breast and thigh muscles were collected for moisture, protein and fat analysis. The pH of small and large intestinal contents was recorded immediately with digital pH-meter. The G treatment showed best FCR (2.356) and the lowest feed intake in comparison to other treatments. Ginger supplementation resulted in meat with optimum tenderness, protein and lowest fat, whereas, GAPF treatment produced meat with lowest protein and highest fat content. The weights of liver, gall bladder abdominal fat, spleen and bursa of different treatments did not differ statistically except that of thymus which was the highest in FA supplemented group in comparison to NC. No effect of different supplementations on pH of the small and large intestinal contents was observed. The highest villous height and crypt depth of duodenum was shown by AA, FA and APF groups, whereas, in jejunum the highest villous height and crypt depth were again shown by FA supplemented birds. In ileum, the highest villous height was shown by GA and the highest crypt depth was observed in FA treatment. The per cent profit earned was the highest in G supplemented group i.e. 51.35 per cent. Overall, the ginger supplemented birds showed 13.43 per cent higher net profit as compared to that of NC and 3.27 per cent as compared to that of PC. It was concluded that the ginger powder supplementation improved the litter quality, and perhaps did not work through pH and morphological modulation of gastrointestinal tract and it did not show synergism with organic acids. The ginger powder supplementation could not only replace the antibiotic, but also enhance the profits compared to that of the antibiotic.
