| ABSTRACT This study was conducted to investigate the effect of a commercial antioxidant (CAO; Rendox Plus®) treatment in stabilizing the poultry byproduct meal (PBPM) and then the subsequent effect of the treated PBPM on growth of broilers. Five batches A, B, C, D and E of PBPM were treated with CAO at 0, 250, 500, 750 and 1000 mL/ton, respectively and stored for 42 days. Oxidative stability of PBPM was estimated on day 0 and then weekly using Peroxide Value and Thiobarbituric Acid tests. PBPMs treated with 750 &1000 mL/ton presented the least oxidation and were selected to be included in broiler diets. A total of 240 one-day-old non-sexed Hubbard broilers were randomly divided into two flocks of 120 birds each. Each flock was further divided into four... |

| ABSTRACT A study was conducted to investigate the influence of selenium nanoparticles (SeNPS) and inorganic selenium supplementation in the drinking water on behavior, performance, and immunity of Arbor Acres® and Ross®308 broilers exposed to E. coli O157:H7 1.6 × 108 challenge at the 10th day of age. 180 one-day-old female broilers were divided into six groups, each with 30 chicks. G1 and G4 were supplied with 1 mL SeNPS 100 mg.L-1/L, G2 and G5 were supplied with 1 mL inorganic selenium 100 mg.L-1/L, and G3 and G6 were supplied with non-supplemented water. Where, G1, G2, and G3 were Arbor Acres®, while G4, G5, and G6 were Ross®308 broilers. A total of 1280 samples (160 sera, 160 intestinal swabs and 960 organ samples including liver, spleen, bursa, heart,... |

| ABSTRACT The objective of the present study was to determine the effects of the gradual dilution of broiler finisher diets with inert or less nutritive materials on growth performance, feed cost, and meat organoleptic properties. Broiler chicks (n=147) were allocated into 49 pens and fed a mash broiler finisher diet (control) or the control diet diluted either with cassava leaf meal (CLM), gliricidia leaf meal (GLM), grass meal (GM), rice bran (RB), sand (SND), or sawdust (SD). For a given diluent, six diets were prepared by mixing the control diet with the respective diluents (w/w) at 0% (fed from 27-28d),2% (fed from 29-30d), 4% (fed from 31-32d), 6% (fed from 33-34d), 8% (fed from 35-36d) and 10% (fed from 37-40d). SD, RB, GLM and GM significantly... |

| ABSTRACT Chicken infectious anemia (CIA) is an immune-suppressive disease caused by chicken anemia virus (CAV). It is characterized by lymphoid atrophy, aplastic anemia, especially in chicks. In this study, full-length genomic characterization of CAV DNA from the broiler flocks in Turkey and phylogenetic analysis were aimed. In the study, CAV DNA were found positive for 37 (53%) flocks with PCR studies from thymus tissues of each 70 broiler flocks. And 17 purified CAV DNA PCR products from these 37 CAV isolates were full length sequenced with the NGS method (Illumina MiSeq). Also with the phylogenetic analyses, full length PCR products of 17 purified CAV isolates have been determined as 2298bp genome size and 99% similarity with each other. The highest... |

| ABSTRACT The feasibility of Laminaria japonica powder (LJP) combined with cecropin as a dietary supplement to enhance broiler growth performance and immune function was evaluated in this study. In total, 648 one-day-old Arbor Acres broiler chicks were randomly distributed into nine numerically-equal treatment groups: T1 (control group; fed a basal diet); T2 (fed the basal diet supplemented with 1% LJP);T3 (fed the basal diet supplemented with 300mg cecropin/kg); and T4,T5,T6,T7,T8 and T9, individually fed with the dietary supplemented with varying levels of LJP and cecropin). Compared with the control, dietary of LJP or cecropin supplementation slightly improved feed conversion ratio (FCR). However, the dietary supplementation of LJP combined with cecropin... |

| ABSTRACT The meal of Jatropha curcas (JCM) seed is a by-product of the biofuel industry and may potentially to be used as animal feed. However, its toxicity has prevented its utilization in animal nutrition mainly due to its high concentration of phorbol esters. This study was conducted to evaluate the effects of the dietary inclusion of JCM on the growth performance, feed digestibility and internal organs development of broilers. Thirty two 48-d-old Ross 308 broiler chickens housed in 16 pens (2 birds/pen) were used in this study. Birds were randomly allocated to dietary treatments comprising four JCM levels (negative control, 25, 50, or 100 g JCM/kg of diet) for four weeks. Results showed that increasing levels of JCM had a negative impact on broiler... |

| ABSTRACT Cardiac troponin (cTnI) and erythrocyte distribution width (RDW) have been used as specific markers for the evaluation of cardiac arrhythmias and myocardial diseases. In this experimental study, we aimed to determine the dose-dependent administration of an Essential OilMixture (EOM) (Eucalyptus globulusLabill, Thymus vulgaris, Cymbopogon nardus, and Syzygiumaromaticum) on the serum erythrocyte indices and myocardial damage. We used 400 male, one-day-old, Ross-308 chicks. Each group ((n=8) (22°C Control (C), C+250 mL/1,000 L, C+500 mL/1,000 L, C+750 mL/1,000 L), 36°C (stress control (SC), SC+250 mL/1,000 L, SC+500 mL/1,000 L, SC+750 mL/1,000 L) was further divided into eight groups with 50 animals. Each group of 50 chicks was further subdivided... |

| ABSTRACT This study aimed to identify the influence of climate pattern and rearing conditions on broiler carcass condemnations observed during processing. We evaluated the registered data of 2015 from the federal inspection files in all broiler slaughterhouses located in the state of Mato Grosso do Sul, Midwestern Brazil. The percentages of condemnations by airsacculitis, cellulitis, dermatosis, ascites syndrome, total carcass condemnations, and average broiler weight at 42 days were analyzed. Data were associated with housing systems and season of the year in which each flock was reared. Two-way ANOVA was applied to the data in a completely randomized design 4×3 (four seasons and three houses) and compared by Tukey's test. The results indicated that the... |

| Modern broilers have been submitted to continuous genetic improvement, and therefore, their nutritional requirements must be constantly updated to ensure their performance. Two experiments were carried out to evaluate different digestible lysine levels for starter (1021 days) and grower (22-35 days) phases. The experiments were carried out with male and female Cobb 500 broilers, distributed according to a randomized block experimental design in a 5x2 factorial arrangement (5 increasing digestible lysine levels x 2 sexes), totaling 10 treatments, with 8 replicates of 22 and 20 birds during the starter and grower phase, respectively. Digestible lysine levels of 1.06, 1.12, 1.18, 1.24, and 1.30 were used in the starter diets (10-21 days) and 0.9, 0.98, 1.04,... |

| ABSTRACT The aim of this study was to determine the effects of the replacement of different levels of protein derived from soybean meal with that from peas in broiler diets on serum protein fractions. A corn-soybean meal basal diet was formulated as the control diet (Control=C) (NRC, 1994), and then pea was added to the control diet to replace 20% (P20) or 40% (P40) of the crude protein of the control diet. The diets were randomly fed to 12 pens per treatment, each housing five birds, for 42 days. Blood samples were collected from 36 birds (3 birds x 4 pens x3 treatments) and the serum protein fractions were separated. Gamma-globulin percentage was higher in group P20 compared with C and P40 groups. Total protein, beta-globulin, and gamma-globulin... |
