In order to determine the response of some tropical grass species to low light situations such as under plantation crops, seasonal cloud cover, etc., six tropical forage grasses were evaluated over a 20 month period on an Oxic Haplustoll in Hawaii (100 m above sea level) under four light regimes (100, 70, 45, and 27/, daylight using polypropylene netting) in the field. The forage grasses evalua...

The effects of high and medium feed value grass silage or maize silage (MS), each offered with a range of concentrate feed levels, and ad libitum concentrate on the performance of finishing lambs, which were either shorn or unshorn, were evaluated. Three silages were used: 1 medium feed value (MFV) and 1 high feed value (HFV) grass silage (DM digestibility [DMD] of 71.3% and 74.5%, respectively...

Nine multiparous (250 +/- 6 d in milk) and 3 primiparous (204 +/- 6 d in milk) Holstein cows were utilized in a 3 x 3 Latin square design to evaluate the lactation performance of cows fed a diet containing dried distillers grains plus solubles (DDGS) with either corn silage or alfalfa hay as forage. Cows were fed total mixed diets containing corn silage (CS), 50% corn silage and 50% alfalfa hay...

a field experiment was conducted in order to study the effect of nitrogen fertilizer and plant density on yield and quality of maize (zea mays l.) cultivar, mv500 silage as second crop. this study was conducted in agricultural research station of kurdistan university during 2012 growing season. the experiment was laid out as split plot based on randomized complete block design with three replic...

Sixty medium-framed Hereford steers averaging 243 kg were used in an experiment including a growing period (28 wk) and a finishing period ending when the animals had approximately 4 to 10 mm of fat thickness (Canadian grade A1). Steers were assigned randomly to a 2 x 3 factorial arrangement of treatments for 28 wk (growing period). From the end of the growing period until slaughter, all steers ...

A completely randomised design study involving 132 continental crossbred beef steers was undertaken to evaluate the effects of method of grain treatment and feed level, and grass silage feed value on animal performance, carcass characteristics and meat quality of beef cattle. Winter wheat was harvested and the grain was stored either ensiled crimped and treated with 4.5 l/t of a proprietary aci...

Replacing dietary grass silage (GS) with maize silage (MS) and dietary fat supplements may reduce milk concentration of specific saturated fatty acids (SFA) and can reduce methane production by dairy cows. The present study investigated the effect of feeding an extruded linseed supplement on milk fatty acid (FA) composition and methane production of lactating dairy cows, and whether basal forag...

The effects of an increasing proportion of crushed linseed (CL) in combination with varying forage type (grass or corn silage) and forage to concentrate ratio (F:C), and their interactions on milk fatty acid (FA) profile of high-producing dairy cows was studied using a 3-factor Box-Behnken design. Sixteen Holstein and 20 Swedish Red cows were blocked according to breed, parity, and milk yield, ...

Magnesium Concentration in Agropyron desertorum Fertilized with Mg and 1st H. F. Mayland and D. L. Grunes2 of humid pastures with N and K often increases the i id of tetany 3 4 nc ence ( , 4). Grass tetany, a Mg deficiency in ruminants, is responsible for large economic losses throughout temperate regions. Significant livestock losses occur in the semiarid western United States primarily when l...
