Approaches for alleviating toxic effects of aflatoxin in lactating dairy cows and weanling pigs
(University of Missouri--Columbia, 2010)Aflatoxin (AF) is a mycotoxin found in feed ingredients used in livestock diets including dairy cattle and pigs. Aflatoxin causes reduced performance, liver damage, increased prevalence of infectious disease, and secretion ... -
Digestible lysine and threonine requirements of male turkeys and their effects on performance of male turkeys fed practical diets to market age
(University of Missouri--Columbia, 2008)Seven experiments were conducted to determine the minimum requirements of digestible lysine (dLys) and digestible threonine (dThr) from 1 to 21 weeks of age for male turkeys. Requirement values were similar to NRC (1994) ... -
Effects of aflatoxin B₁ (AFB₁) on hepatic gene expression in pigs and turkeys
(University of Missouri--Columbia, 2013)The objective of the present study was to evaluate the efficacy of curcumin (CMN), an antioxidant supplied by turmeric (Curcuma longa) powder to ameliorate the adverse effects of aflatoxin B1 (AFB1) on performance of pigs ... -
Effects of aflatoxin on hepatic gene expression in a poultry model
(University of Missouri--Columbia, 2008)To determine the effects of dietary aflatoxin on hepatic gene expression in chicks, seventy five day old-male broiler chicks were assigned to three dietary treatments (0, 1 and 2 mg/kg aflatoxin/kg of feed) from hatch to ... -
Effects of continous administration of low-dose of Escherichia coli lipopolysaccharide in chicks and poults fed non toxic doses of aflatoxin B1 and T-2 toxin
(University of Missouri--Columbia, 2005)Six studies (three with broilers and three with turkeys) were conducted to determine if E. coli lipopolysaccharide (LPS) would enhance the effects of aflatoxin B1 (AFB1) and the T-2 toxin (T-2) in chicks and poults fed ... -
Effects of dietary melamine and cyanuric acid in young broilers and turkey poults
(University of Missouri--Columbia, 2011)Six studies were conducted to determine the individual and combined toxicity of melamine and cyanuric acid (up to 3.0%) in young broilers and turkey poults. Melamine alone caused reduced growth, increased kidney weights, ... -
Effects of dietary melamine and cyanuric acid in young Pekin ducks and weanling pigs
(University of Missouri--Columbia, 2012)In 2007, melamine (MEL) and cyanuric acid (CYA) were added to feed ingredients in an attempt to artificially increase their crude protein and thus their momentary value. However, once ingested MEL and CYA can form insoluble ... -
Evaluation of modified montmorillonites in poultry diets
(University of Missouri--Columbia, 2007)The present work was conducted to determine if modification of MONTs with Cu and Zn would enhance the protection of broiler chicks against the adverse effects of AF, and to determine if the modified MONTs would be bioavailable ... -
Evaluation of the efficacy of high levels of microbial phytase in broilers
(University of Missouri--Columbia, 2006)Three experiments were conducted to evaluate the efficacy of high levels of microbial phytase in broiler diets. In experiment one (EXP 1), phytase was included in the diets at 0, 250, 500, 10,000, and 20,000 PU/kg diet. ... -
Phosphorus digestibility of corn and soybean meal (SBM) in broilers : in search of a consistent and reliable model to quantify individual ingredient contribution
(University of Missouri--Columbia, 2017)Two experiments were conducted to determine true digestibility of Phosphorus (P) in feed ingredients commonly in commercial broiler diets. A second objective was to determine if the true digestible P values of corn and ...
