The aim of this study, comprising two experiments, was (1) to determine in Experiment 1 the relationship of incremental dietary P (phosphorus) content on precaecal digestible P in male broilers and (2) to determine in Experiment 2 the precaecal P digestibility of various inorganic P sources at marginal levels of P supply. In Experiment 1, a total of 260 male Ross 308 broilers were divided into ...

Two studies were conducted utilizing 270 chickens to evaluate the efficacy of yeast culture (YC) for both broiler and layer ayian types. In the first experiment, three dietary levels (0, 1.25, 2.50 percent) of YC were included in a nutritionally complete ration and fed to 14-day-old broiler chicks for 8 days. Body weight gain, feed consumption (g) and feed efficiency were not influenced by yeas...

Inorganic P is often added to growing horse diets because organic P, or phytate-P, is believed to have lower digestibility. If horses can efficiently digest organic P, then the need for inorganic P may be reduced. Much of the P in grain-based concentrates fed to growing horses is in the form of phytate-P. Little is known about the ability of growing horses to degrade phytate-P or whether horse ...

Faba bean is a legume used as a food source by humans and animals. However, it presents antinutritional factors such as tannins and phytic acid, compounds that form complexes with proteins and minerals, respectively, decreasing faba bean’s digestive value. Faba bean was treated with tannase and phytase, the effect of this treatment was measured in a study with rats, a group received a diet with...

The effects of Ca and P (CaP) levels and micromineral sources on mineral digestibility were evaluated in growing pigs. Treatments consisted of 2 levels of CaP and 3 trace mineral (TM) treatments arranged as a 2 × 3 factorial in a randomized complete block design with 8 replicates. The CaP levels evaluated were: 1) 0.65% Ca and 0.55% P [standard CaP (Std CaP)], and 2) 1.00% Ca and 0.85% P (High ...

the present study describes the radiation-induced effects on nutritional quality and on anti-nutritional factors of sorghum grain: effects of electron beam (er) and gamma irradiation (gr) at doses of 10, 20 and 30 kgy and infrared irradiation (ir) at 60, 90 and 120 s on the chemical composition, mineral content and bioavailability, in vitro protein and starch digestibility, total phenolic compo...

An experiment was conducted to test the hypothesis that the dietary inclusion rate of P does not influence the digestibility of P. The experiment was conducted at 4 experiment stations where the same protocol was followed. A total of 60 growing pigs (initial BW: 22.22 +/- 2.13 kg) were allotted to 6 dietary treatments with 10 replications per treatment. All pigs were placed in metabolism cages ...

the aim of this study was to determine the effects of ensiling and using of fertilizers nitrogen and phosphorus on chemical composition and ruminal dm degradability of safflower plant (carthamustinctorius l.). the safflower plant was cultivated at december 2009, and harvested at june 2010 in flowering stage, chopped to 3-5 cm particles and then ensiled in the laboratory silos for 60 days. the e...

The effects of dehulling and micronization (infrared heating) on the nutritive value of three cultivars (Impala, Radley, and Sirius) of peas (Pisum sativum) varying in coat color for broiler chickens were studied. Dehulling increased (P < or = 0.05) protein and starch contents and decreased (P < or = 0.05) fiber content of peas. Also, the concentrations of most amino acids slightly increased (P...
