BACKGROUND We investigated in rats the effects of feeding different forms of high amylose maize starches (HAMS) rich in resistant starch (RS) to understand what the implications of RS heterogeneity might be for colonic biology, including innate cellular responses to DNA-damage. METHODS A range of maize starches were compared: digestible cornstarch (Control), HYLON® VII, Hi-maize® 1043, Hi-mai...

In this paper we present stable isotope information (dC in bone collagen and apatite, and dN) in order to discuss the significance of maize consumption in the human diets of central western Argentina. We also contribute bioanthropological information based on the study of caries, hypoplasia, cribra orbitalia and dental abscess frequencies. This study shows a large variability in the significanc...

Three hundred (300) 21d old (Arbor-acre) broiler chicks apportioned to five (5) dietary groups of sixty (60) birds each, further replicated six (6) times were fed graded levels toasted pigeon pea seed meal (TPSM) assess the performance, flock uniformity, organ weights, carcass yield and hepatic histology at finisher phase. A maize-full-fat soybean diet served as control (I). The TPSM was incorp...

Effects of feeding grain and maize silage from a non-Bt maize and a variety of Bt maize that contains cry1F (event TC1507, event DAS-Ø15Ø7-1), a gene that provides maize with insect resistance, on the health and performance of dairy cows were evaluated. In a crossover trial, 20 lactating Holstein cows were assigned to each of 2 dietary treatment groups and fed diets containing whole-plant maize...

I . A total of six diets based on maize silage were formulated to examine the effect of proteinand non-protein-nitrogen, and energy supplementation on the flow of amino acids to the small intestine and the synthesis of microbial amino acids in the rumen of growing cattle. All diets contained 24 g total nitrogen (N)/kg dry matter (DM), of which 550 g N/kg total N was supplied by either urea or f...

Duodenal infusions of methionine and ly-sine have been shown to increase milk protein yield in dairy cows given a dehydrated maize diet (Rulquin, 1987). As du-odenal amino acids (AA) profiles vary according to diet (Le Henaff, unpublished), a trial was undertaken to test the lactational responses of dairy cows to methionine and lysine infusions with 3 other diets based on either maize silage (M...

background: identifying the potential of livestock and forage plants of each region is a way to compensate the lack of forage, and efficient use of edible resources of the country. milk thistle is a medicinal plant which may be used as fodder for native livestock of khuzestan province. objectives: the purpose of this research was to study  the effects of different levels of milk thistle on rume...

ACAC), and fatty acid synthetase (FAS) were studied in male Wistar rats after a period of starvation and refeeding of diets containing 400 g glucose, or raw or cooked starches as the source of carbohydrate/kg. Starches fed included maize, potato, wheat, rice, and tapioca. 2. When compared to the responses of rats given the glucose-containing diet, rats given raw maize-or rice-starch-containing ...

Orange maize is being promoted as a source of provitamin A carotenoids (pVAC) in Zambia. Carotenoid retention in orange maize grains stored in metal silos, multilayer polyethylene and common woven bags, and maize meal packaged in single and multilayer polyethylene bags was evaluated. Significant differences in total pVAC retention were found between grain storage methods (48.1-57.2%) after 6mon...
