Abstract
Manipulation of fatty acids of poultry meat to reduce heart related disorders has become focus of attention in modern life style. A total of 160 day-old broiler chicks were distributed into four groups. All the chicks were fed on commercial ration for 4 weeks and provided flaxseed (FS) at the rate of 0 (FS–0), 10 FS–10), 15 (FS–15) and 20% (FS–20) in the feed. Myristic, palmitic, stearic and archidic acids were reduced (P<0.05) when flaxseed level was increased. Lowest (P<0.05) concentration of palmitoleic, oleic, myrestoleic and eruccic acids were recorded in meat from group supplemented with higher amount of flaxseed (FS–20). Linoleic, alpha linolenic, gamma linolenic, eicosatrienoic, eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) content of broiler meat increased (P<0.05) with increasing the amount of flaxseed in broiler feed. Arachidonic acid decreased significantly (P<0.05) in response to flaxseed supplementation in broiler feed. Total omega-6 fatty acids also increased (P<0.05) with higher supplementation of broiler feed with flaxseed. Flaxseed may be supplemented in broiler ration up to 10% for decreasing saturated and mono saturated fatty acids (MSFAs) and increasing poly unsaturated fatty acids (PSFAs) in broiler meat without affecting feed intake, weight gain, and feed conversion ratio.

Abstract
The aim of this study was to determine the effect of yeast based organic selenium (Se) on post-partum progesterone concentration, blood metabolites, service period and milk yield. Dairy Jersey cows (n=15) having almost similar body weight, age, parity and body condition score were divided into three groups of equal number. One group served as a control that was given no Se supplementation. Second and third groups were supplemented with Se at the rate of 0.3 and 0.4 mg/kg of dry matter intake, respectively. The results revealed that after parturition, there was significantly (P<0.05) higher concentration of progesterone in Se treated group of Jersey cows (P<0.05). Week wise, concentration of progesterone in blood increased significantly (P<0.05). There was a decrease in length of service period in Se treated groups. Blood concentrations of glucose, cholesterol and triglyceride increased significantly (P<0.05) on weekly basis. However, these blood metabolites did not change significantly between the control and Se treated groups. Milk yield did not change significantly between the control and Se treated groups. The results of current study indicated that supplementation of yeast based organic Se at the rate of 0.4 mg/kg dry matter intake improved the progesterone concentration and decreased the service period but had no effect on blood metabolites and milk yield.

Abstract
The present study was conducted to find the effect of different levels of organic minerals on egg production and egg quality of laying hens. A total of 45 laying hens were selected and divided into three groups with 3 replicates of 5 birds each. The control group was provided with commercial ration having inorganic minerals and the other two groups were supplemented with organic minerals at the rate of 7.5 (OM-50) and 15 mg/kg (OM-100). The experiment lasted for 5 weeks including 1 week of adaptation period. Overall feed intake was significantly higher (P<0.05) in the control. Significantly lower feed intake was recorded in group OM-100. Numerically lower (better) FCR was recorded in OM-100 at all recorded stages. Significantly (P<0.05) higher egg weight, egg shell weight and egg shell thickness was found in OM-100 compared to the control. Similarly, albumin height, Haugh unit and yolk weight were significantly (P<0.05) higher in M-100. It was concluded from the present results that organic minerals at the level of 50 and 100 mg/kg improved the performance and egg quality of laying hens. However, better results were found in OM-100.

Abstract
The aim of the present study was to find the effect of Potenmic supplementation on humoral immunity, some blood metabolites and stress status in broiler. A total of 150 day old broiler birds were divided into five treatment groups. One group was control having crude protein and metabolizeble energy of 22% and 3000 Kcal/kg respectively as a basal diet. Second group was basal diet + 1ml Potenmic dissolved in 1.5 lit of water (NCPot1), third group was basal diet plus 1 ml Potenmic dissolved in 3 lit of water (NCPot2), fourth group was basal diet + 1 ml Potenmic dissolved in 5 lit (NCPot3) of water. Every group was divided into three replicates and each replicates was consisting of 10 birds. Antibody titre against ND was significantly (P<0.01) higher in NCPot1 and NCPot2 in comparison with the control. However, antibody titre against IB was significantly (P<0.05) higher in the treatment groups compared to the control. The H:L was significantly (P<0.01) lower in NCPot1 and NCPot2. Blood glucose was significantly (P<0.01) higher in the treatment groups compared to the control. However, NCPot1 and NCPot2 showed significantly (P<0.05) higher serum glucose and protein concentration compared to the control and other treatment groups. Blood MDA concentration was also significantly (P<0.05) lower in NCPot1 and NCPot2 compared to the control. The results of the present study showed that supplementation of Potenmic improved the immune response, blood metabolites and antioxidant status of broiler.
