A few previous studies have shown that heat processing may increase the bioavailability of phytate-P in some foodstuffs. Therefore, two chick experiments were conducted to determine the effect of various increased heat processing treatments on bioavailability of P in DDGS. In addition, two precision-fed cecectomized rooster assays were conducted to evaluate the effects of the heat treatments on...

There is currently much ongoing research and interest for developing new processing technologies to produce corn distillers dried grains with solubles (DDGS). The current study evaluated a high protein (HP) DDGS and a dehydrated corn germ meal which are the products that can be produced by a modifi ed dry milling process. To evaluate the nutritional characteristics of these products, a chick ex...

OBJECTIVE The objective of this experiment was to characterize the mRNA expression profile of type IIb sodium-inorganic phosphate cotransporter (NaPi-IIb) and the biochemical values of serum alkaline phosphatase (AKP), calcium, inorganic phosphorus, tibial ash and minerals of broiler chickens with aging. METHODS A total of 56 one-day-old Arbor Acres male broiler chickens were used. Broiler ch...

We studied the ability of broiler chickens to adapt to early moderate P and Ca deficiencies by evaluating the impact of feeding different concentrations of P and Ca, from 1 to 18 d, on performance, bone characteristics, and nutrient absorption in the grower (Gr) period (18 to 32 d). Two starter (St) diets were fed from 1 to 18 d: a control (C) diet [0.45% nonphytate P (nPP) and 0.9% Ca] and a l...

From hatch to 18 d of age broilers were fed starter diets with (0.9 kg/ton) or without direct fed microbial (DFM). At 18 d, birds were weighed and, within DFM treatment (trt), randomly assigned to battery pens. In Exp 1, a 2 x 2 factorial arrangement of nutrient density [control (C, 19.3% protein (CP), 0.84%, Ca 0.37% nonphytin P (nPP); and 17.1% CP, 0.8% Ca, and 0.3% nPP in the grower (Gr) and...

Five experiments were conducted to determine Lys and P bioavailabilities of distillers dried grains with solubles (DDGS), which was derived from corn fermentation in a modern nonbeverage ethanol plant. In experiment 1, we used the precision-fed cecectomized rooster assay and estimated the true digestibility of Lys in DDGS to be 75%. In experiments 2, 3, 4, and 5 the relative bioavailabilities o...

Three series of experiments were conducted with fast-growing chickens in order: to evaluate the effects of dietary Ca and P on cholecalciferol metabolism and expression; to determine dietary Ca requirements; to determine dietary P requirements. The results of the first series confirmed previous results on the effects of dietary Ca and P on some variables of vitamin D metabolism and expression, ...

This experiment was conducted to investigate the effect of phytase supplementation in diets reduced amino acids ( AA ), crude protein CP and phosphorus P ) on growth performance, carcass traits, tibia ash broiler chickens. A total 2,240 unsexed Ross 308 chickens were used 56 floor pens with 40 birds each fed one eight dietary treatments seven replicates until 35 d age. positive control PC diet ...
