摘 要:Country level assessment of feed supply and demand for livestock in Pakistan was conducted for the year 2013. Availability of feed ingredients was calculated from the official crop production statistics using published harvest index and extraction ratios, and their nutrient supply was estimated from local feed composition tables. Feed requirements of livestock species were calculated from the standard tables published by US National Research Council. The results showed that indigenous feed resources were short for livestock and poultry requirements. The supply and demand gap for dry biomass, crude protein (CP) and metabolizable energy (ME) were 19.4%, 37.2% and 38.0%, respectively. Crop residues were the predominant source comprising 58.8% of the total feed supply, while fodder and grazing shared 23.8% and 9.2%, respectively. Grains and by-products contributed 8.2% to the feed supply. In attempt to fill this gap, large quantities of oilseed meals were imported mainly for the poultry sector. Maize was the major feed grain used in poultry and ruminant rations, and they together consumed 79% of the country's total maize produce. Based on the anticipated rapid expansion in poultry, dairy and feedlot farming in Pakistan, the feed gap will further enlarge and this warrants future focus on efficient and intensive utilization of the local conventional and nonconventional feed resources. The data and information presented in this paper provided a sound basis for regular updating in future to attain sustainable growth of livestock sector in the country.
