a chick bioassay with chemically defined amino acid (aa) diets was conducted to compare four different aa profiles: the nrc (1994), feed stuff, rhone poulenc animal nutrition (rpan) and illinois ideal chick protein (iicp) aa profiles. this battery study involved male and female chicks during grower (21 to 42 days of age) period. indispensable aas were rationed to lysine according to requirement...

Three new lignans (1 - 3), together with four new thymoquinol glycosides (4 - 7), were isolated from 70%-EtOH extract of the rattan stems of Schisandra chinensis. The structures of 1 - 7 were elucidated by detailed spectroscopic analyses, and these new compounds were identified as pinobatol-9-O-β-d-glucopyranoside (1), 1,2,13,14-tetramethoxydibenzocyclooctadiene 3,12-O-β-d-diglucopyranoside (2)...

The purpose of this study was to evaluate the effect of natural clinoptilolite (NCLI) and modified clinoptilolite (MCLI) on broiler performance, gut morphology, and its relation to gut circumstances. A total of two hundred forty 1-d-old male chicks were randomly assigned to 3 treatments, each of which comprised 8 pens of 10 chicks per pen. Birds in the control group were fed the basal diet, whe...

Segregation and medicated early weaning are technologies used to optimize the productivity and health of pigs, but these practices may also cause aberrant behaviors indicative of stress. Thus, differences in early- (=10 d of age) and late- (=30 d of age) weaned pigs were investigated. At weaning, pigs were housed in groups of four in 16 pens (eight pens per treatment) in the same facility, and,...

320 one-day male broilers (ross 308) were divided in 4 treatments (with 4 replicate and 20 chicks for a replicate). all of broilers reared under a cold environmental temperature to induce ascites .experimental treatments were included 1: was fed a commercial corn-soybean meal- based diet meeting nrc (1994) including 1.2% arg and 40 iu of vitamin e/kg (control), 2: control with 400 iu of vitamin...

Two experiments were conducted on postpartum suckled beef cows synchronized with Syncro-Mate B and artificially inseminated approximately 48 h after implant removal. In Exp. 1, cows (> or = 42 d postpartum at the timed AI) were randomly assigned to treated (n = 101) and control (n = 85) groups on d 12 after the timed AI. Treated cows received norgestomet/silicone implants that were left in situ...

The aim of the present study was to evaluate the effects of canola bioactive peptides (CBP) produced by enzymatic hydrolysis of canola meal on performance, digestive enzyme activity, nutrient digestibility, gut microflora and intestinal morphology of broiler chickens. A total of 250 one-day-old Ross 308 male broiler chicks were randomly allocated to 5 dietary treatments with 5 replicates of 10 ...

OBJECTIVES To compare the efficacies of medium-dose fluticasone propionate (FP), medium-dose triamcinolone acetonide (TAA), and combined low-dose FP plus salmeterol (SL). DESIGN Randomized, double-blind, triple-dummy, multicenter, 12-week clinical trial. SETTING Allergy/respiratory care clinics. PATIENTS Six hundred eighty patients with asthma previously uncontrolled with low-dose inhaled...

A total of 360 weanling barrows (Line 200 × 400, DNA Genetics; initial BW 12.4 ± 0.05 lb) were used in a 42-d study to evaluate yeast-based pre- and probiotics (Phileo by Lesaffre, Milwaukee, WI) diets with or without pharmacological levels Zn on growth performance fecal dry matter (DM). Pens assigned 1 4 dietary treatments 5 pigs per pen 18 pens treatment. Dietary arranged 2 factorial main eff...
