The present study was aimed to assess the influence of brown marine algae and vitamin E (VE) (160 ppm α-tocopheryl acetate) on stability of chicken meat enriched with fish oil. In this study, 360 d-old broilers (Arbor Acres Plus) were randomly assigned to 6 treatment groups with 4 replicates of 15 birds in each. Experimental groups consisted of corn-soybean basal diet (C), corn-soybean basal di...

Take Home Messages • The diversion of corn away from livestock to the production of ethanol is likely to increase in the future, so corn prices at the dairy farm are likely to remain high for the foreseeable future. Corn prices are about 50% greater now compared to 8 months ago. • Alternative grain sources high in starch are too expensive or unavailable in Florida. Hominy can partially replace ...

background and objectives: unhygienic poultry feedstuffs can lead to nutrient losses and detrimental effect on poultry production and public health. in the present study, mycobiota and colony-forming units per gram in ingredients and finish poultry feed was evaluated with special reference to potentially mycotoxigenic fungi. materials and methods: eighty five samples of corn, soybean meal and p...

A methodology was developed to estimate quantities of crop residues that can be removed while maintaining rain or wind erosion at less than or equal to the tolerable soil-loss level. Six corn and wheat rotations in the 10 largest corn-producing states were analyzed. Residue removal rates for each rotation were evaluated for conventional, mulch/reduced, and no-till field operations. The analyses...

The additivity of true amino acid digestibility (TAAD) and true metabolizable energy (TME) values in corn, soybean meal, and wheat red dog for White Pekin ducks was investigated. Differences between observed values for the complete diets and values predicted from measurements of individual ingredients were used to test additivity. Eight ducks were each assigned to the following dietary treatmen...

Understanding soil organic N (ON) pool enrichment may help explain why rates of N fertilization required to attain maximum corn (Zea mays L.) yields are usually lower for corn following soybean [Glycine max (L.) Merr.] than for corn following corn. Our objectives were to quantify the ON pools within a 16-ha Iowa field and to correlate those results with corn yield. Spring and fall measurements ...

Approaches to restore productivity eroded soils are urgently needed sustain food security. We evaluated plant response soil-landscape rehabilitation, in which approximately 15 cm of topsoil was moved from depositional landscape positions the upper slope. Crop monitored for 6 yr a corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotation at severely site and 4 wheat (Triticum aestivum moderat...

An experiment was conducted to determine the effects of soybean meal (SBM) particle size on broiler performance, particularly P utilization. This experiment utilized a 2 x 2 x 2 factorial design with the following variables: SBM particle size, P level, and diet type, either corn-SBM or semipurified. SBM was obtained from a processing plant before (geometric mean diameter 1,239 microm) and after...
