Jalauni sheep are found in the Bundelkhand region of Uttar Pradesh and Madhya Pradesh states in India. About 37% of the geographical area of this region is under cultivation and about 86% of the population, mostly directly or indirectly dependent on agriculture, live in villages. Forests, cultivable waste and barren land occupy more than 50% of the area, permanent pasture and other grazing lands about 9% and miscellaneous tree crops and grasses about 0.7%. The livestock census figures of 1977 and 1997 indicate an annual declining trend of 0.04 % in the sheep population in Uttar Pradesh and Madhya Pradesh states. Characterization and evaluation of Jalauni sheep under field conditions were undertaken to establish the norms, morphological characteristics and performance parameters of this breed. A total of 78 households were visited in 29 villages in five districts. Information on feeding, breeding and management practices, utility patterns etc. and production and reproductive performance was collected through personal observations and interaction with the farmers. Body weight and/or body measurements were recorded for 374 animals. Average adult body weights of male and female Jalauni sheep were 35.5±2.1 and 27.2±0.7 kg respectively. Age at first lambing was 1.5 to 2 years and lambing interval one year. A ewe, on an average, delivers 7–9 lambs in her lifetime.
