~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Second FAO Electronic Conference on Tropical Feeds Livestock Feed Resources within Integrated Farming Systems ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Abstract of the sixteenth paper, from A. Salman. Questions that might stimulate discussion on this topic include: 1. Do you have experience in supplementing stubble grazing with urea multinutrient blocks? 2. Do you have experience in replacing part of the urea by other sources of non protein nitrogen, such as poultry manure? 3. Have you used blocks formulae where the traditional binders (cement and quick lime) were totally replaced by locally available binders such as clay or fuelwood ashes? 4. Do you think that multinutrient blocks are a good medium for distributing by-pass proteins? 5. In your area, is the major benefit of using urea multinutrient blocks the improvement of reproductive performance? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ THE ROLE OF MULTINUTRIENT BLOCKS FOR SHEEP PRODUCTION IN INTEGRATED CEREAL-LIVESTOCK FARMING SYSTEM IN IRAQ Ala D. Salman IPA Agricultural Research Center, P.O. Box 34094 Baghdad-Iraq E-Mail: c/o ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ABSTRACT One of the main limiting factors affecting sheep production in Iraq is the shortage of feed resources, especially protein. Cereal stubble grazing and hand-feeding of chopped straw are the main components of the sheep diet for a considerable part of the year. Multinutrient blocks were manufactured from urea and locally available agro-industrial by-products. The potential of multinutrient blocks as supplementary feed for sheep was investigated in several on-station and on-farm experiments. The results of these experiments indicate the value of multinutrient blocks as supplementary feed for sheep in Iraq. Using multinutrient blocks during cereal stubble grazing improved the ewes' weight gain (47-100%), conception rates (7-27%) and twinning percentage(26%). Using multinutrient blocks during the ewes' hand-feeding period resulted in replacement of 40% of costly barley grain. The adoption of multinutrient blocks by sheep owners is considered as a major breakthrough in animal feeding in Iraq. Although this technique was introduced to Iraq only a couple of years ago, the total of multinutrient blocks produced during 1995-96 campaign has reached 15,000 tons manufactured mainly by private plants (13 out of 14), and used by nearly 4,000 sheep owners buying the blocks at cost price plus 30% marginal profit.
