Floral diversity and nutritional value of forages in Pulikulam cattle breeding tract

Documenting the floral diversity in the Pulikulam cattle breeding tract (Sivaganga, Madurai and Virudhunagar districts in Tamil Nadu) and the nutrient content of predominant forages were important for maintaining Pulikulam cattle under zero input grazing system of management. Hence, a study was carried out to document the forage biomass, botanical composition, and nutritional profile of the forages present in the Pulikulam cattle breeding tract. The number of edible forage species other than shrubs and trees documented in the grazing tract at Sivaganga, Madurai and Virudhunagar districts was 10, 8 and 9, respectively. Pennisetum clandestinum recorded significantly (p <0.05) highest biomass (133.25, 148.25 and 115 g/m²) and botanical composition (31.32, 34.99, and 26.31%) in all the districts. Variability was observed in proximate principles, fiber fractions and mineral contents between forages. Zinc was not detectable in Aristida setacea and both zinc and copper were not in detectable levels in Echinochloa colona.
