Abstract

Sheep and goats in Pakistan have not been able to produce to the best of their potential. This may primarily be attributed to under feeding and malnutrition. Ranges have been depleted due to overgrazing and mismanagement and are not in position to feed the existing small ruminant population. To overcome the shortage of good quality fodder and balanced feed supply, the alternate means like cereal straws and other crop residues are being commonly used. Sunflower crop residues like stalks and heads provide a good quality forage for livestock. These crop byproducts are rich in crude protein and lower in crude fibre. Their inclusion in the diet of small ruminants at 20, 30 and 40 percent levels in ration has shown significantly (p < 0.05) increased feed intake and weight gain. Daily feed intake was 1,130, 1,180 and 1,750 g for sunflower crop residue, soybean crop residue and wheat straw, respectively, when added at the rate of 20 percent in the ration. The drymatter digestibility of sunflower, soybean crop residues and wheat straw was also comparable. The maximum performance of the animals was observed at the 20 percent level of inclusion of sunflower crop residue in the diet.
