Effects of defaunation and dietary urea on some hematological parameters in Ramlic lambs

18225

This study was conducted to determine the effects of defaunation and adding urea to ration in place of plant-originated protein sources on the levels of some hematological parameters in Ramlic lambs. Forty 2.5-3 months of aged, and approximately 16 kg weighed male ramlic lambs were used in the study. The animals were randomly divided into four groups as follows: faunated + control diet (F); defaunated + control diet (D); faunated + experimental diet (F+E); and defaunated + experimental diet (D+E). The groups F and D were fed with a control concentrate diet containing plant protein as a nitrogen source whereas the groups FE and DE were fed with the concentrate diet supplemented with urea and sulfur, both at 3% of live weight per day. The forage portion of the diet was 350 g of dry alfalfa hay per animal per day. Diets were fed twice daily in equal amounts. The experimental period lasted 90 days totally. At the end of the investigation, erythrocyte and leukocyte counts, haemoglobine amount, hematocrite level and differential leukocyte percentages were determined in the blood samples taken from the animals. There were no differences in erythrocyte and leukocyte counts, haemoglobine amount, hematocrit level, the lemphocyte, neutrophil, monocyte and eusinophil percentages of differential leukocytes among the groups. The basophil percentages in the defaunated groups (D and D+E) were higher (P 0.05) than those in the faunated groups (F and F+E). We concluded that defaunation, or feeding a diet supplemented with urea in place of plant-originated protein sources had not a negative effect on hematological parameters in the lambs.
