sunflower has many dry forage yields and is richer than corn in inorganic matter, protein and calcium. therefore, use of this forage in livestock diets can be valuable for elimination of food poverty. in order to determine the best harvest stage for sunflower silage, an experiment was conducted in 2007-2008 at agricultural faculty of shahid chamran university of ahvaz. a randomized complete blo...

a number of 36 holstein young bulls (initial bw of 345±61 kg) were randomly assigned to 6 dietary treatments, following a 3 × 2 factorial arrangement, with three concentrate levels of fish oil (0, 1.5 and 3 % of dm) and 2 levels of alfalfa hay versus corn silage (10 and 20 % of alfalfa hay forage versus 20 and 10 % of corn silage) were used to investigate the effect of fish oil supplementation ...

Much of the variation in forage dibut there have been few significant breeding efforts specifically dedicated to improving maize forage yield or quality by breeders in the gestibility can be ac...

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...

Forages are the most important ingredient in a dairy cow’s ration. She is a ruminant and to be a healthy, productive cow she needs a healthy, productive rumen. High quality forages are the key to achieving a healthy rumen and a productive cow. However, because of the importance of forages in maintaining rumen health and cow performance, when deficiencies in the amount or quality of the forage i...

Short description: In Bavaria, feeding cattle with maize silage is a common method, which is practiced even in for maize unfavorable locations. With increasing feed costs a partial substitution of maize by grass silage could be economically reasonable. Especially against the background of bioenergy production from cereals and maize, a competitive situation can evolve and grass as feedstuff can ...

Particle size alterations during neutral detergent fiber (NDF) determination and in situ rumen incubation were analyzed by dry sieving and image analysis to evaluate the in situ procedure for estimation of NDF degradation parameters and indigestible NDF concentration in terms of particle size. Early-cut and late-cut grass silages, corn silage, alfalfa silage, rapeseed meal, and dried distillers...
