The authors compared histories of nonmalignant respiratory diseases (asthma, bronchitis, emphysema, hay fever, and pneumonia) in 1,553 lung cancer patients and 1,375 healthy controls enrolled in a Texas case-control study from 1995 to 2003. They incorporated data on two biologically relevant polymorphic genes, matrix metalloproteinase-1 and myeloperoxidase. Emphysema was associated with a stati...

Four groups of seven dairy cows were given hay plus high-fibre concentrates based on sugar-beet feed (hay-concentrate, 40:60 w/w) or high-starch concentrates based on flaked maize (hay-concentrate, 20:80 w/w), with a crude protein (nitrogen x 6.25) content of either 160 or 220 g/kg dry matter, over weeks 4-18 of lactation. Performance during week 3 of lactation, when all cows were fed on a stan...

this experiment was conducted to investigate the genetic diversity, relationship between morphological, agronomic and qualitative traits and to identify components of forage yield using some multivariate statistical methods in local sainfoin populations. the experiment was conducted as randomized complete block design with three replications in agricultural and natural resources research center...

Sorghum is a Poaceae family plant that produces lot of hay. A field experiment was carried out at the University Thessaly’s experimental farm to investigate hay yield and quality characteristics six different sorghum varieties (V1: Buffalo grain, V2: Elite, V3: Big Kahuna, V4: 25K1009, V5: 4264, V6: 5D61) under nitrogen fertilization levels (N1: 0, N2: 80, N3: 160, N4: 240 kg ha−1, using urinar...

This study was carried out to compare in situ and in vitro enzyme techniques for determining estimates of forage escape proteins. Eight forages (vetch hay, wheat silage, corn silage, wheat hay, grass hay, lentil straw, triticale hay and alfalfa hay) were used as feed materials. During 70 h, incubation with enzyme method had similar escape protein values for vetch hay, wheat hay, grass hay, trit...

Grass hay exports are an important sector of the agriculture of the irrigated Sonoran Desert. These grass hays are exported to the Orient from West Coast ports. Bermudagrass, kleingrass, and sudangrass are the grass hay crops that are exported. The grading standards for these grass hay exports are quite variable and very subjective. Some of the primary determinants of export hay grades are colo...

Three 2.4-ha wheat (Triticum aestivum L.) fields were used to test the effects of maturity at harvest (boot vs. dough) and preservation method (hay vs. silage) on forage yield, chemical composition, and animal performance when fed in mixed diets. Forages were incorporated into 4 diets in a 2 x 2 factorial arrangement of treatments with hominy feed, soybean hulls, and cottonseed meal as the prim...
