Effective manure management to efficiently utilize organic wastes without causing environmental degradation requires a clear understanding of the transformation of P forms from diet to manure. Thus, the objective of this study was to establish quantitative relationships between P forms in diets, feces, and manures collected from U.S. Northeastern and Mid-Atlantic commercial dairy farms. Total P...

In a 148-d feedlot experiment, 48 crossbred steers were fed a 70% sorghum diet with clinoptilolite (CLN), a natural zeolite, substituted at 0, 1.25 and 2.5% of the diet dry matter. No differences (P>.05) were detected in average daily gain, feed intake (dry matter and organic matter) and feed efficiency among treatments. Negative correlations (P<.05) between fecal starch and fecal pH were detec...

this paper considers the potential problems that may militate against the adoption of organic poultry production in nigeria. factors identified include: higher risk of diseases like coccidiosis and newcastle disease, disease prevention and control / herd health management, disease containment in times of outbreak, land acquisition (land tenure system), market economies / cost-benefit ratio, pas...

A study was conducted to determine the efficacy of organic (Se-yeast, SelenoSource AF, Diamond V Mills Inc., Cedar Rapids, IA) and inorganic sources of Se on growth performance, tissue Se accretion, and carcass characteristics of growing-finishing pigs fed diets with high endogenous Se content. A total of 180 pigs at 34.4 +/- 0.06 kg of BW were allotted to 1 of 5 dietary treatments: a negative ...

Cockles Cerastoderma edule were fed two different concentrations ( approximately 0.8 and 2 mm(3) l(-1)) of two diets with different qualities ( approximately 10 and 60% of organic content) which were achieved by mixing different proportions of ashed silt particles with cells of the microalgae Tetraselmis suecica. Clearance, ingestion and absorption rates of organic matter and biochemical compon...

for determination the effect of lemon pulp levels and organic acid premix (globacid) on performance, carcass traits,immune system, biochemical parameters and intestinal morphology of broilers, 288 ross broilers were used in 3×2 factorial arrangement with three levels of lemon pulp (0, 1.5 and 3 percent) and two levels of globacid (0 and 0.1 percent) in a completely randomized design with six tr...

This paper considers the potential problems that may militate against the adoption of organic poultry production in Nigeria. Factors identified include: higher risk of diseases like coccidiosis and Newcastle disease, disease prevention and control / herd health management, disease containment in times of outbreak, land acquisition (land tenure system), market economies / cost-benefit ratio, pas...

The objective of this experiment was to measure the apparent total tract digestibility (ATTD) and the retention rate of Zn, Cu, Mn, and Fe in pigs fed either inorganic or organic sources of Zn, Cu, Mn, and Fe. The experimental design was a randomized complete block design with a 2 × 3 factorial arrangement of treatments. There were 2 types of diets (corn grits-based or corn-soybean meal [SBM]-b...
