Zein is the major storage protein of corn and comprises :45–50% of the protein in corn. It was first identified in 1897, based on its solubility in aqueous alcohol solutions. Zein isolate is not used directly for human consumption due to its negative nitrogen balance and poor solubility in water. Current zein manufacture is limited to :500 tonnes per year from corn gluten meal. Zein sells for :...

Alkaline protease producing microorganism Vibrio metschnikovii NG155, isolated from the soil samples of leather industry, having potential application in dehairing of animal skin was used in this study. To enhance the production of protease by this strain, various physical and nutritional factors were optimized using statistical methods like Plackett Burman and Response Surface Methodology. In ...

1 Dry distillers grains improved gain and efficienicy relative to corn. Heifers supplemented daily consumed more hay and gained faster, but were not more efficient than those supplemented three times weekly. Summary An experiment was conducted with 120 crossbred heifers to determine the value of dry distillers grains (DDG) in high-forage diets, and to evaluate the effect of supplementing daily ...

Most medium formulations for improving culture of entomopathogenic nematodes (EPN) based on protein sources have used enriched media like animal feed such as dried egg yolk, lactalbumin, and liver extract, among other ingredients. Most results, however, showed unstable yields and longer production time. Many of the results do not show the detailed parameters of fermentation. Soy flour, cotton s...

Two experiments were conducted to determine the digestibility of energy and nutrients and the concentration of DE, ME, and NE in fermented soybean meal (FSBM), conventional soybean meal (SBM-CV), and fish meal fed to weanling pigs. In Exp. 1, 36 barrows (initial BW: 22.0 ± 3.85 kg) were placed in metabolism cages and allotted to a randomized complete block design with 4 diets and 9 pigs per die...

Five ruminally, duodenally, and ileally cannulated sheep (average BW 62 kg) were fed 65% roughage: 35% concentrate diets (CP = 15%) in a 5 x 5 Latin square design to study the applicability of using a combination of defaunation with N supplements (soybean meal [SBM], corn gluten meal [CGM], blood meal [BM], urea, and casein) with different extents of ruminal degradation to manipulate microbial ...

In two experiments, 720 broiler strain cockerels were used to determine the effect of pressure and temperature on poultry offal meal (P.O.M.) quality. Poultry offal meals were subjected to 20, 28 and 35 pounds per square inch gauge (p.s.i.g.) steam pressure for <1 or 15 minutes (Experiment 1) and 15, 30 and 45 p.s.i.g. steam pressure for 15 or 30 minutes (Experiment 2). All pressures were allow...

Producers of organic vegetables often report that weeds are their most troublesome production problem. Corn gluten meal (CGM), a by-product of the wet-milling process Qf corn, is phytotoxic. As a preemergence or preplant-incorporated herbicide, CGM inhibits root development, decreases shoot length, and reduces plant survival of weed or crop seedlings. The development of a mechanized application...

Forty-eight grower pigs were used to evaluate the effects of feeding low phytic acid (LPA) corn, LPA soybean meal, normal corn (NC), normal soybean meal (NSBM), and phytase on nutrient digestibility and excretion. Barrows were blocked by BW (initial BW=45.3+/-1.6 kg) and randomly assigned to 1 of 8 dietary treatments in a 2 x 2 x 2 factorial arrangement (6 pigs/treatment). Pigs were fed twice d...
