Ambient temperature and relative humidity are two crucial climatic factors that heavily influence poultry production and management. Knowledge of the period during which the environmental conditions remains detrimental is crucial for successful and economic poultry production and resource management. The objective of the study is to identify and comparatively assess the most crucial months/periods during which the climatic condition hinder normal performance of dual purpose Vanaraja poultry in topographically and agro-climatically distinct locations. The average monthly temperatures and humidity of each location were compared with established critical limits of ambient temperature and relative humidity that influence poultry for the location. Results reveal that there are wide inter-location variations in sensitive period during the year and affect the performance of the introduced poultry with varied intensity. Also the cultural & management practices should be location-specific with incorporation of need-based seasonal modification leading to optimum resource use. With critical periods in mind farmers can adopt/frame appropriate and well-timed management practices to alleviate impact of adverse environmental conditions.

The extraordinary knowledge of indigenous people about their immediate environment and natural resource base can be a great asset for conservation of biodiversity. The current study aims to investigate an indigenous method of grazing management through temporary confinement of Mithun (Bos frontalis) of whole village community in a well selected area in the forest during the cropping and growing season. The whole system is called Lura and practiced by Galo tribes of Eastern Himalayan region of India. Every year Lura management committee is formed that selects a new site based on number of Mithuns, forage availability, time period and several other key criteria without affecting flora-fauna diversity and rare medicinal plants. The practice checks continuous, free, random and selective grazing by Mithuns. It prevent continuous disturbance of soil surface due to treading, during growing and rainy seasons that avoid soil erosion and compaction, and facilitate seedling germination and the invasion by plants. Change of site, provide resting period to the forages in the previous Lura site especially during growth stage that allow them to renew and regenerate appreciably within 1-2 months. It also saves resources and time for construction of fencing in each Jhum and other agricultural site of each farmer. The confinement offers easy monitoring, protection and regular health assessment of the livestock. Thus, it is a multifaceted indigenous practice that ensures grazing management, biodiversity conservation, protection of standing agricultural crops and animal health management
