Abstract (The full text in Persian language)
The effect of Kochia scoparia and Atriplex dimorphostegia on some serum electrolytes, metabolites, thyroid’s hormones and intracellular enzymes and urine parameters of Baloochi ewes was determined. The ewes were randomly allocated to three dietary treatments [T1: kochia + alfalfa (1:1), T2: atriplex + alfalfa (1:1), and T3: alfalfa] in a Latin Square experiment in three 28 days periods. During the last 3 days of each period, samples of blood serum and urine were collected. The effect of treatments on blood serum glucose and urea N was significant (P<0.05). The T1 and T2 in compared with T3, decreased the serum concentration of Ca and tri-glyceride (P<0.05), whereas increased cholesterol level (P<0.01). Ewes fed T1 had highest serum activity of glutamicoxaloacetic transaminase (P<0.05) and glutamic-pyrovic transaminase (P<0.01) (93.0 and 34.8 U/L, respectively). Halophyte forages elevated serum tetraiodothyronine, tetraiodothyronine index (P<0.01) and total bilirubin, conjugated bilirubin and free bilirubin (P<0.05). The urine volume and urine Na excretion was significantly higher (P<0.05) for T2. In ewes fed kochia, the urine excretion of urea N was higher (P<0.001) than ewes which fed with Atriplex. It was concluded that the energy requirements of ruminants fed Kochia or Atriplex need more attention.
