The effect of Pioglitazone and Curcumin on lipid metabolism and plasma metabolites of broiler breeder was investigated as a completely randomized design with three treatments and four replications by using of 60 hens at age 45 weeks during 10 weeks. Experimental treatments including: 1) Control (basal diet), 2) Adding 20 mg/bird/day Pioglitazone to diet and, 3) Adding 20 mg/bird/day Curcumin to diet. At the end of experiment, blood samples were collected, and birds were slaughtered. The results showed that hens receiving Pioglitazone or Curcumin had higher egg production and shell thickness when compared with control group (p<0.05). However, the yolk and egg weight of birds in the control group were higher than two another groups (p<0.05). Plasma concentrations of glucose, triglycerides and cholesterol were lower in hens feeding Pioglitazone or Curcumin than control (p<0.05). Liver and abdominal fat weight and adipocyte diameter were lower in birds receiving Pioglitazone or Curcumin (p<0.05). Based on current results, dietary supplementation of Pioglitazone or Curcumin, through lowering plasma lipids and subsequently positive influence on abdominal fat tissue and liver, could improve production in broiler breeders.

The aim of the current study was to evaluate the effects of the guanidinoacetic acid (GAA) supplement on the semen freezability of broiler breeder roosters. Experiments were performed with twenty Ross commercial strain broiler breeder roosters in four treatments and five repeats in a complete randomized design. Roosters were fed a diet containing 0% (control), 0.06%, 0.12% and 0.18% GAA supplement for eight weeks. Semen samples were collected weekly by abdominal massage. In order to equilibrate the temperature, semen samples were diluted with an extender and placed inside the refrigerator at 5 ° C. Samples were then packed into straws, exposed to nitrogen vapor and finally moved into liquid nitrogen containers. After freezing-thawing, the total and progressive motility, viability, morphology and membrane integrity of spermatozoa were assessed. The mean of total motility at the 0.12% and 0.18% levels were significantly higher than that of other groups (P
