In this study the effects of L-lysine hydrochloride (containing 78.8% available lysine as crystalline lysine) and L-lysine sulfate (containing 51% available lysine in bacterial cell mass) as source of supplemental lysine in broiler chickens was assessed. The basal diet was supplemented with either L-lysine hydrochloride or L-lysine sulfate to meet lysine requirement. Lysine supplementation irre...

A 2 × 2 factorial experiment was conducted to investigate the interactions between laminarin (LAM; 0 and 300 parts per million (ppm)) and fucoidan (FUC; 0 and 240 ppm) levels on intestinal morphology, selected microbiota and inflammatory cytokine gene expression in the weaned pig. There was an interaction between LAM and FUC supplementation on the Enterobacteriaceae population (P< 0·05) and the...

Condensed fermented corn extractives (liquid steep liquor) was assessed as an alternative to organic acids in broiler chicken. Day-old Ross 308 chicken (n = 180) were allocated into six treatments (basal diet with no supplement, basal supplemented 1 and 2 cc/kg liquid liquor (CSL) or formic acid along probiotic (1 × 108 CFU/g, Lactobacillus acidophilus, casei) a completely randomised design fiv...

the main purpose of this study was to investigate the effects of euphorbia hirta and acidifiers supplement on resistance of broiler chickens against salmonella enteritidis infection. a total of 120 day-old male broiler chicks were randomly assigned to 3 dietary treatments. 1) basal diet, 2) basal diet supplemented with 2 g/kg organic acid (oa) and 3) basal diet supplemented with 7.5 g/kg e. hir...

The effects of cinnamaldehyde (CINN) on in vitro parameters of immunity and in vivo protection against avian coccidiosis were evaluated. In vitro stimulation of chicken spleen lymphocytes with CINN (25-400 ng/ml) induced greater cell proliferation compared with the medium control (P < 0·001). CINN activated cultured macrophages to produce higher levels of NO at 1·2-5·0 μg/ml (P < 0·001), inhibi...

The main purpose of this study was to investigate the effects of Euphorbia hirta and acidifiers supplement on resistance of broiler chickens against Salmonella enteritidis infection. A total of 120 day-old male broiler chicks were randomly assigned to 3 dietary treatments. 1) basal diet, 2) basal diet supplemented with 2 g/kg organic acid (OA) and 3) basal diet supplemented with 7.5 g/kg E. hir...

The potential benefits on human health have prompted an interest in developing nutritional strategies for reducing saturated and increasing specific unsaturated fatty acids (FA) in ruminant milk. The impact of the level and type of starchy concentrate added to diets supplemented with sunflower-seed oil on caprine milk FA composition and on mammary, omental and perirenal adipose, and liver lipid...

The bioavailability of threonine in soybean meal and the effects of the excess amino acids in soybean meal on the estimate were measured using rats and chicks in slope-ratio assays. In Exp. 1, a corn-based diet containing .23% threonine was supplemented with 0 to 45% L-threonine in .05% increments. The growth rate of weanling rats fed these diets increased quadratically (P less than .001) with ...

studies have shown that aflatoxin is immunosuppressive and its ingestion in feed has resulted in decreased immunity in vaccinated birds .therefore, the purpose of the present study was to determine the efficacy of sodium bentonite (sb) and esterified glucomannan (e-gm) of yeast cell wall, in counteracting the toxic effects of aflatoxin (af) on immunization against infectious bursal disease (ibd...

An experiment with growing lambs was designed to test the hypothesis that alterations in blood acid-base status would influence intake of corn silage. Six wethers (29 kg) were fed a diet of corn silage (36% DM, 8% CP) supplemented with 1.25% urea and .2% sulfur. At feeding time, sodium bicarbonate (NaHCO3) and sodium sesquicarbonate (NaSC) were added to the silage at levels of 0, 2% or 4% of di...
