A study was conducted to investigate the effects of Bacillus amyloliquefaciens CECT 5940 as a direct-fed microbial (DFM) alone or in association with bacitracin methylene disalicylate (BMD) broilers under enteric pathogen challenge. total 1,530-day-old male Cobb500 chicks were randomly assigned 5 treatments, 9 replicate pens 34 birds each. Treatments included positive control (PC, basal diet without additives challenge); negative (NC, additive and challenged birds); NC + 0.05 g/kg BMD; 1 DFM...
This research describes the modification of a glassy carbon electrode with spent coffee grounds hydrochar (HDC) and copper nanoparticles (CuNPs) for simultaneous determination hydroxychloroquine sulfate (HCS) bisphenol A (BPA). Scanning electron microscopy, EDS cyclic voltammetry were used to characterize nanocomposite. The analytical parameters optimized sensing platform was applied HCS BPA using square-wave (SWV). For HCS, linear range from 1.0 μmol L−1 50 L−1, an LOD LOQ 0.46 1.53...
Abstract A total of 56 Hy‐line W‐36 hens from 28 to 30 weeks were used on nitrogen balance (NB) trial estimate daily N maintenance requirements (NMR) and the genetic potential for retention (NR max T). The treatments consisted six graded levels in diets (N1 = 8; N2 16; N3 24; N4 32; N5 40; N6 48 g N/kg feed), formulated using dilution technique. regression analyses between intake excretion performed fit exponential function determine NMR 292 mg/BW kg 0.67 , which was applied further...
1. A nutrition model is described that may be used to optimise the amino acid of laying-type pullets prior onset lay. It not a method optimising lifetime laying performance.2. The potential growth and composition body, feathers, ovary oviduct are from hatching age at which sexual maturity attained, daily energy requirements for average individual in population can calculated.3. There two parts approach used, first being description itself second how required information was gathered. number...
Context Genetic improvements in modern strains have led to continuous increments broiler growth rates, which, as a consequence, resulted higher economic returns for producers over the last decades. Aim The present study was conducted characterise potential of body and feathers Cobb 500, Hubbard Flex Ross 308 male female broilers, well assess changes chemical composition that occur up 16 weeks age. Methods Birds were fed isoenergetic diets divided four phases formulated marginally exceed...
Abstract Experiments were conducted to estimate daily N maintenance requirements (NMRs) and the genetic potential for retention (NR max T) of pullets in growth phase. Three nitrogen balance trials conducted, a total 48 Hy‐line W‐36 used each trial age periods (starter: 14–28, grower: 56–70 developer: 98–112 days). The treatments consisted six graded levels diets (L1 = 8, L2 16, L3 24, L4 32, L5 40 L6 g N/kg feed), formulated using dilution technique. regression analyses between intake...
A digestibility assay was conducted in order to determine the coefficients (DC) of amino acids feed ingredients cecectomized adult roosters. In total 48 roosters were used assess coefficient 7 ingredients: corn, soybean meal, concentrate, corn gluten wheat bran, peanut and feather meal. Each ingredient replicated six times a group 6 rooster measure endogenous acid losses. After hours fasting, tube fed 20g tested twice during day. At 12 hour-intervals excreta losses collected immediately...
ABSTRACT An experiment was conducted to evaluate broiler chicken performance and carcass yield in response carbohydrase supplementation (Xylanase Betaglucanase; XB) association of phytase (PHY). A total 1,920 day-old male chicks (Cobb 500) were distributed a completely randomized design with 8 treatments replicates each, allocated 64 pens 30 each. The were: Positive Control (PC); Negative (NC): reduced ME [-120kcal/kg (Starter) -170kcal/kg (Finisher)]; NC + XB [50g/ton]; [100g/ton];...
