Fat and protein metabolism in growing steers fed either grass silage or dried grass.
Cattle fed grass silage diets have been reported to have high carcass fat:protein ratios. The effect of grass silage and dried grass diets, fed at different levels of intake to ensure a range of equivalent metabolisable energy intakes (MEI) from 1 .1 x metabolisable energy requirement for maintenance to ad libitum, on fat and protein metabolism in twenty-four Hereford x Friesian steers was inve...
متن کاملRumen and blood variables in steers fed grass silage or whole-crop fodder beet silage
The objectives of this study were (i) to examine the effects on rumen and blood variables when grass silage (GS) was replaced with whole crop fodder beet silage (FBS) in the diet of beef cattle, and (ii) an abrupt change from GS to FBS. Six rumen-fistulated Friesian steers (initial bodyweight (BW) 416 kg, SD 43) were offered GS ad libitum for four weeks. The dry matter (DM) consumed daily by ea...
متن کاملSource and feeding level of nitrogen on growth and carcass characteristics of beef steers fed grass as hay or silage.
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 ...
متن کاملIngestive Behavior of Heifers Feeding with Marandu Grass Silage
The present study was aimed at assessing the ingestive behavior of ¾ Zebu × Holstein heifers confined to different levels of substitution of sorghum silage by marandu grass silage. Twenty heifers were used with initial average weight of 346.25 kg, divided into completely randomized experimental design with 5 repetitions and the following treatments: treatment 1) roughage fraction of the diet co...
متن کاملEvaluation of protein supplementation for growing cattle fed grass silage-based diets: a meta-analysis.
The objective of this meta-analysis was to develop empirical equations predicting growth responses of growing cattle to protein intake. Overall, the data set comprised 199 diets in 80 studies. The diets were mainly based on grass silage or grass silage partly or completely replaced by whole-crop silages or straw. The concentrate feeds consisted of cereal grains, fibrous by-products and protein ...
