The aim of this experiment was to investigate the effects of partial replacement of corn silage with long alfalfa hay and/or coarse chopped wheat straw on biochemical parameters in late lactating Holstein primiparous dairy cows. Twelve late lactating Holstein primiparous cows including four cows equipped with a rumen cannula, averaging 210 ± 20 days in milk and weighing 575 ± 50 kg were randoml...

With the recent commercialization of transgenic rootworm-resistant maize with high levels of antibiosis to larval feeding, the biology of western corn rootworm, Diabrotica virgifera virgiferaLeConte, on hosts beyondmaize,Zea maysL., has become an important topic for which data are limited.Larval survivorship andgrowthparametersweremonitoredon the roots of 29plant species comprised of maize, mai...

The study was designed to determine whether products of fermentation in corn silage could limit its voluntary intake. Six rumen-cannulated Hereford steers were assigned randomly to diets of corn silage (CS) and dried corn forage reconstituted either with water (DC + W) or with extracts from corn silage (DC + CSE) according to a crossover design with three experimental periods. During each perio...

Amaranth ( sp.) is a C plant adapted to poor soils and regions with limited rainfall and high temperatures. The plant is characterized by a yield of up to 85 t/ha, CP concentration of up to 28.5% of DM, and DM digestibility of 59 to 79%, which may vary depending on the species and variety. The potential of this plant as a forage source for ruminants has not been completely considered. This stud...

the objectives were to investigate the effects of addition of alfalfa hay as an absorbent on fermentationquality and effluent production of corn silage. three levels of corn forage with dry matter (dm) contentsof 18.3, 21.7 and 25.5 percent were supplemented with 0, 5, 10, and 20 percent alfalfa hay, on as fedbasis, and ensiled in three replicates in polyvinyl chloride mini-silos in a completel...

Two trials were implemented to explore nutritional strategies to improve lactation performance of dairy cows fed red clover silage (RCS)-based diets. In Trial 1, 18 earlyto midlactation dairy cows were assigned to a replicated 3 × 3 Latin square trial design and fed diets containing forage bases of all RCS, a mixture of RCS and brown midrib corn silage (BMR), and a mixture of RCS and normal cor...

in order to study the effects of different sowing dates by some of companion crops on the weeds control, morphological traits and yield of corn sc 504, a field experiment was carried out of research field at tabriz university during 2010 growing season. treatments were arranged in a factorial experiment using randomized complete blocks design with three replicatins. factors was include four lev...

BACKGROUND AND OBJECTIVES Ensiling is a conservation method for forage crops. It is based on the fact that anaerobe lactic acid bacteria (LAB) convert watersoluble carbohydrates into organic acids. Therefore, pH decreases and the forage is preserved. The aim of this study was to isolate special kinds of lactic acid bacteria from silage and to study the effect of bacteria, inulin and enzymes as ...
