One hundred twenty eight adult healthy broiler breeders were used and these were randomly divided into four groups. The treatments were control (basal diet) and treatment groups were fed with supplementary organic zinc as 20 ppm (T1), 40 ppm (T2) and 60 ppm (T3).The blood sample were collected and plasma biochemical constituents were analysed. In male broilers, higher dose of zinc (T3) fed group showed significantly (P<0.05) higher in serum calcium, enzymes like Alkaline phosphatase, aspartate transaminase and reduced total cholesterol and total protein and there was no significant (P>0.05) difference serum phosphorus, triglycerides, alanine transaminase and uric acid. In case of female broilers feeding zinc T3 treatment group showed significantly (P<0.05) higher level of calcium, phosphorus, total protein, ALP, AST and increased the total cholesterol content. There was no significant difference was noticed in Alanine transaminase and uric acid level. In conclusion, supplementing the diet of broiler breeder chickens with zinc caused significant increase in serum plasma and cholesterol contents in this study. Therefore, zinc can be used as efficient feed additive for enhanced physiological status of birds. Keywords: Broiler breeder, cholesterol, triglycerides, zinc Introduction Zinc is important component of many metalloenzyme concerned with numerous biochemical functions in body. The plasma zinc concentration is a valid and useful indicator of the size of exchangeable pool of zinc. A reduction in the plasma zinc level reflects a loss of zinc from its target organs (bones and liver) and an increased risk to the development of metabolic and clinical signs of zinc deficiency (King, 1990) [5] . Zinc plays a major role in control of appetite, enhanced immune function, reduced reactive oxygen species (ROS). Similarly, Zinc plays an important role in the breeders as the affects the secretion of various reproductive hormones, testicular development and differentiation and in turn affecting the reproductive performance. Hence, the present study assessed the effect of supplementation of organic Zn on the serum biochemical constituents in the broiler breeders. Material and method Selection and feeding management of birds The experiment with organic zinc was carried out for 8 weeks using 32 males and 96 females of Caribro Vishal adult breeders. The birds are randomly divided into four groups, in each group carrying 24 female and 8 male. The treatment groups were control (basal diet), T 1was supplemented with 20 ppm zinc methionine, T2 with 40 mg ppm and T3 60 ppm in addition to basal diet. The birds were maintained under uniform standard managemental conditions in individual cages. In this study organic form of zinc as zinc methionine (Mintrex® Zn, Novus Pvt. Ltd.,) was used. Sample collection and analysis Blood was collected in both male and female birds randomly and serum was separated. The plasma samples were collected and analysed for total protein, calcium, total cholesterol, triglycerides uric acid and transaminase enzymes activities such as alanine transaminase, aspartate transaminase and alkaline phosphatase were analysed using kit protocol (Corel Clinical Systems, Goa).
