2. Effect of Exogenous Protease, Mannanase, and Xylanase Supplementation in Corn and High Protein Corn DDGS Based Diets on Growth Performance, Intestinal Morphology and Nutrient Digestibility in Broiler Chickens
ABSTRACT A study was conducted to evaluate the effects of exogenous enzymes supplementation in high protein (Hi-Pro) corn DDGS-based diets on broiler growth performance, intestinal health, and nutrient digestibility. A total of 200 one-day-old broiler chicks were randomly allocated to four dietary treatments with five replicates of 10 birds each. A basal die

3. Stabilization of Rice Bran in Broiler Feed with Natural and Synthetic Antioxidants and Heat Treatment
ABSTRACT The objective of this study was to evaluate different strategies for the oxidative stabilization of rice bran (RB) in the diet of broiler chickens using natural antioxidant additives, synthetic antioxidant additives and heat treatment on performance, breast meat quality and liver fat content and the nutrient digestibility coefficients. Furthermore,

4. Effects of Dietary Supplementation with Red Algae Powder (Chondrus crispus) on Growth Performance, Carcass Traits, Lymphoid Organ Weights and Intestinal pH in Broilers
ABSTRACT The aim of this study was to determine the effects of dietary supplementation with red algae powder (Chondrus crispus) on the growth performance, carcass traits, lymphoid organ weights and intestinal pH y in broiler chickens. A total of 300 1-day-old B34 line male broiler chickens were randomly allotted to three treatments, four replicates per treat

5. Influence of Artemisia Annua on Broiler Performance and Intestinal Microflora
ABSTRACT The present study aimed to investigate the effect of Artemisia (Artemisia annua) supplementation as essential oil and powder, in broiler diet on performance and intestinal microflora. One hundred and eighty Cobb 500 broiler chicks assigned to three experimental groups (six replicates with 10 broilers per replicate) were housed in an environment-cont

6. Morphological Investigations of the Effect of Thermal Manipulation During Embryogenesis on Body Performance and Structure of Pectoral and Thigh Muscle of Ross Broiler Chicken
ABSTRACT The aim of this study was to determine the optimum timing of thermal manipulation during early, mid, late and long lasting embryogenesis that may result in improvement of body performance and myofiber development (fiber diameter and thickness of perimysium) of pectoral and thigh muscles by a comparative morphometrical investigation on post-hatch day

8. Performance, Carcass Traits, Biochemical and Hematological Profile, Ileal Microbiota and Nutrient Metabolizability in Broilers Fed Diets Containing Cell Wall of Saccharomyces Cerevisiae and Piperine
ABSTRACT The objective of this study was to evaluate the inclusion of cell wall of Saccharomyces cerevisiae (CWSc) and piperine in broiler rations and their effects on performance, carcass traits, blood parameters, ileal microbiota and nutrient digestibility. A randomized block design with five treatments and six replicates of 10 birds was used, totaling 300

10. Cardiac Indicators, Serum Antioxidant Activity, and Growth Performance as Affected by Hawthorn Extract (Crateagus oxyacantha) in Pulmonary Hypertensive Chickens
ABSTRACT Hawthorn has been traditionally used to improve blood circulation and medicating cardiac disorders as well as blood stasis and elimination of pulmonary hypertension. An experiment was conducted to evaluate the effect of different levels of hawthorn extract in the drinking water on cardiac indicators, serum antioxidant activity, growth and immunity o
