A feeding experiment was conducted to investigate the effect of fermented Terminalia catappa fruit meal (FTCM) with Aspergillus niger as replacement for maize on broiler growth performance, nutrient digestibility, and serum biochemical constituents. Dietary maize was replaced by FTCM at 0, 20, 40, 60, or 80%. One hundred and eighty one-day-old Shaver broiler chicks were randomly allocated to th...

Introduction Formulating diets according to the ideal protein concept allows for maximizing nitrogen utilization and minimizing nitrogen excretion [1]. One primary benefit of ideal protein is that once a ratio is established for a certain age, one can calculate the requirement of all other amino acids under a variety of conditions based on the digestible lysine (dLys) requirement [2]. Digestibl...

Lower available P (aP) was used as a base value in nutritional strategies for mitigating P pollution by animal excreta. We hypothesized that the mechanism regulating phosphate transport under low dietary P might be related with the AMPK signal pathway. A total of 144 one-day-old Arbor Acres Plus broilers were randomly allocated to control (HP) or trial (LP) diets, containing 0.45 and 0.23% aP, ...

Octacosanol, which has prominent physiological activities and functions, has been recognized as a potential growth promoter in animals. A total of 392 1-d-old male Arbor Acres broiler chicks with similar body weight were randomly distributed into four dietary groups of seven replicates with 14 birds each supplemented with 0, 12, 24, or 36 mg octacosanol (extracted from rice bran, purity >92%)/k...

This study investigated the effect of wild grape (Vitis coignetiae) dietary supplementation on the antioxidative potential and quality of the breast and leg meat of broilers. A total of 36 one-day-old male Cobb broiler chicks were obtained from a commercial hatchery, and randomly assigned to 9 pens with 4 birds per pen. Then, broilers were fed 3 different dietary supplementations, including 0%,...

The 42-day long trial was performed on a total of 48 Hybro broilers divided into four groups. After a 14 day pre-experimental period, the experimental groups were treated daily with T-2 toxin at 0.02 mg/kg BW for 7, 14 or 21 days respectively and a mixture of ethanol and physiological saline was administered to the control group of birds. Liver samples were taken after the period of toxin admin...

OBJECTIVE This study was conducted to investigate effects of zinc (Zn) bearing palygorskite (ZnPal) supplementation on growth performance, hepatic mineral content, and antioxidant status of broilers at early age. METHODS A total of 240 1-day-old Arbor Acres broiler chicks were allocated into 5 treatments with 6 replicates of 8 chicks each. Birds in 5 treatments were fed a basal diet supplemen...

This study was envisaged to comprehensively profile genes in selected tissues along with a few biochemical indicators and integrate resulting information with dietary selenium (Se) deficiency symptoms in broilers. A total of 120 one-day-old Cobb male broilers were equally divided into two groups and fed a Se deficient corn-soybean-based basal diet supplemented with 0.3 mg/kg sodium selenite (Co...

background: broilers lung mechanisms that regulate endothelin (et) in the lung are complex and poorly understood. objectives: methods: in this experiment lung et-1 mrna levels and lung mrna expression for the et(a) receptors were determined in lung tissue weekly (term = 42 days, intervals = 7 days). serum endothelin concentration was also measured at these ages. results: the study showed that e...

background:herbal methionine can be compared relative todl-methionine with evaluation of bioavailability of this source ofmethionine. objectives: an experiment was carried out todetermine the relative bioefficacy of herbal methionine (h-met)®relative to dl-methionine (dl-met) on performance criteria andimmunocompetence of met sources in male broilers. atotal of 160male broilers were fed a met-d...
