"The dietary LA had no effect on growth rates (body weight, abdominal fat, breast muscle, and liver). The higher level of LA increased plasma non-esterified fatty acid and decreased plasma triacylglycerol concentrations only at 6 weeks of age. A 42% increase in hepatic respiration was observed in the 4-week-old chickens given 50 mg LA/kg diet. In Expt 2, 3-d-old female broiler chicks were treated with or without dietary LA at 50 mg/kg. At 30 and 31 d old, isoproterenol (2 mg/kg body weight per h) was continuously infused into a wing vein for 2 h, and changes in plasma glucose, triacylglycerol, and non-esterified fatty acid concentrations were analysed.
Note: Isopretenol is a beta-agonist.
Isoproterenol increased plasma glucose over basal levels maximally at 60 min.
Note: Without ALA.
Now, with ALA:
Furthermore, the glucose increase in the LA-treated chickens was 35% greater than that of the controls at this time.
"
Ok, it says that the glucose increase in the LA-treated chickens was higher. But which group? The 50mg/kg group or the 5mg/kg group? Or is it an average of the two groups?
Basically, how are you justifying the 50mg/kg dosage?
