Twelve early lactation Holstein cows (4 fistulated) were used in replicated 4x4 Latin squares with 4-wk periods to determine the effective neutral detergent fiber (NDF) content of wet corn gluten feed and to measure the effect of forage particle size on ruminal mat consistency and passage rate of wet corn gluten feed. Diets were 1) 23.3% NDF (17.4 percentage units of NDF from alfalfa silage), 2...

S INCE there is an enormous production of corn in the United States, a complete knowledge of its nutritive value is of scientific interest and may be of great economic importance. Yellow dent corn is too low in protein and its protein is too deficient in essential amino acids, especially lysine and tryptophane, to be fed most efficiently to growing pigs in drylot without a good protein suppleme...

T HE extent of infection of the corn grain by fungi of various kinds is an important item in the grading of corn by physical or chemical means or by performance tests. It may also be an important item in the feeding value of the grain for livestock. Mitchell and Beadles (i94o) have studied the impairment in the nutritive value of corn by various types of ear rot, using growing albino rats as te...

The base temperature for germination of corn is approximately 10°C, which results in slow germination and emergence of corn crops sown into cool soils. The effects of plant-growth-promoting rhizobacteria (PGPR) and kinetin on grain and sweet corn emergence, plant growth and yield were studied under short season conditions in 1996 and 1997. Two PGPR strains (Serratia proteamaculans 1-102 and Ser...

Twelve lactating Holstein cows were utilized in a repeated switchback design to evaluate milk production and milk fat composition responses to wet corn distillers grains. Total mixed diets consisted of 31.4% corn silage, 18.4% alfalfa hay, and either 50.2% of a concentrate mix that contained mostly corn and soybean meal or 19.4% of a concentrate mix that contained mostly corn and 31.2% wet corn...

Advanced Corn Silage Production 605. Circle all correct answers and Discuss. 1. With corn silage, high grain yield reduces fiber production per acre. a. True. b. Likely. c. Doubtful. d. False. e. Conditional. 2. Delaying harvest decreases digestibility of NDF from corn silage. a. True. b. Likely. c. Doubtful. d. False. e. Conditional. 3. More mature corn silage has less NDF only because it is d...

The spatial variation in plant species associated with intercropping is intended to reduce resource competition between species and increase yield potential. A field experiment was carried out on corn (Zea mays L.) and soybean (Glycine max L.) intercropping in a replacement series experiment with weed contamination consist of: weed free, infestation of redroot pigweed, infestation of jimsonweed...

Popcorn was evaluated in a series of experiments conducted over four growing seasons for its potential as a refuge for European corn borer, Ostrinia nubilalis (Hübner). Objectives of these studies were to determine whether more larvae were produced in popcorn than in field corn and to determine how popcorn influenced female oviposition and larval distribution in neighboring field corn. Two vari...

Attraction of wild male fall armyworm, Spodoptera frugiperda (J. E. Smith), was compared in trapping experiments during 2005-2009 in Florida. Traps were baited either with a commercial sex pheromone lure or corn and rice strain females obtained from laboratory colonies. Over 6,900 male moths were collected, and a large subset (>1,500) of these moths was analyzed for their host strain identity. ...

Two trials were conducted to evaluate the effects of corn or dried beet pulp on intake and digestibility of forage by lambs and on IVDMD. In Trial 1, 16 lambs (average BW = 41 +/- .9 kg) were used in a randomized complete block design with eight lambs per block. Lambs were fed a crested wheatgrass hay (7.5% CP) and received either no supplement (NS), a protein supplement (PS), or protein supple...
