The effects of feeding diets containing sunflower and wheat middlings pre-treated with fibredegrading enzymes were investigated. Based on hatch body weight (BW), 288 Ross-708 male broiler chicks placed in cages (six birds/cage). Diets were: 1) positive control (PC), a maize–soybean control; 2) negative (NC), PC plus untreated meal (USM) (UWM); 3) four test which USM UWM replaced (TSM) (TWM) at ...

A trial was conducted to evaluate the effect of fat emulsifier on fat utilization in broiler chickens using 240 days old chicks which were divided into 24 replicates in a 3×2 factorial arrangement under Completely Randomized Design (CRD). Experimental diets were formulated using 1, 2 or 3% fat with or without fat emulsifier (Lecithin) at 350 mg kgG1. The trial lasted for 35 days and was divided...

Two experiments were conducted to investigate the effect of low-CP diets supplemented with crystalline amino acids, according to an ideal amino acid ratio, on the performance, plasma metabolites, nutrient digestibility, nitrogen balance, and water intake in male and female chickens from 1 to 48 d of age using a 4-phase feeding program: prestarter (1-7 d), starter (8-21 d), grower (22-35 d), and...

Forty-eight barrows and forty-eight gilts (PIC 337 sires x PIC C22 dams) were evaluated to determine the effects of feeding ractopamine hydrochloride (RAC) and different cereal grains on the carcass and fat quality in late finishing pigs. The study was carried out using four replicates with 24 animals in each replicate (four pigs per pen, six pens per replicate, two replicates per slaughter dat...

Abstract The objective of this study was to evaluate the vitamin D3 (vitD) and 25-hydroxy D (25-OHD) requirements for finisher pig performance bone density. Seventy-two pigs (62 ± 11.1 kg BW) were allotted 36 pens (n = 2 pigs/pen) across 4 dietary treatments 9 pens/trt) 51 d. Corn-soybean meal mash diet were: 1) Diet containing 75 IU/kg vitD; 2) 150 vitD (NRC requirement); 3) 750 4) As 1 plus 0...

A trial was conducted to determine the effect of low-protein diets with constant ME:CP ratio on performance and carcass characteristics of broilers from 1 to 35 d of age. Four experimental diets were formulated to have 4 levels of CP and ME, respectively, in each phase: 23, 22, 21, and 20% CP with 3,036, 2,904, 2,772, and 2,640 kcal/kg in the starter phase (1 to 10 d); 22, 21, 20, and 19% CP wi...
