Effect of vitamins,probiotics and low protein diet on lipid profile,hormonal status and serum proteins level of molted white leghorn male layer breeders

Supplements including vitamin e,vitamin c,probiotics,12% crude protein diet and combination of all these treatments on lipid profile,hormonal status and serum proteins level of post-molt white leghorn male breeders. for this purpose 270 commercially available male layer breeders at the age of 59 weeks were procured and introduced to zn-induced molting after which supplemented feed was given. serum samples were collected to assess the lipid profile including triglycerides,total cholesterol,hdl-cholesterol,ldl-cholesterol; hormonal status including triiodothyronine (t3),thyroxin (t4),thyroid stimulating hormone (tsh),cortisol and serum proteins level including albumin,globulin and total protein to evaluate the effect of supplements on general health status of post molt birds. results showed that as a whole,vitamin c and probiotic treatments helped in improvement of lipid profile and vitamin e helped in improving thyroid hormones level. vitamin c helped in a better way in declining corticosterone level as compared to other groups. probiotics and combination treatments helped in improving serum proteins level. to the best of our knowledge,this is the first time that effect of these treatments is evaluated in molted male layer breeders.
