Effects of Monensin on Dry Matter Intake, Milk Production and Healthy Transition Holstein Dairy Cows

est in morning (Holt and Hilst, 1969; Orr et al., 1997; Barrett et al., 2001). Herbage SC and digestibility conHerbage soluble carbohydrate (SC) levels vary diurnally and livecentrations also vary seasonally, with generally higher stock intake can be higher for herbage harvested or allocated to animals in the evening than in the morning. Few assessments of SC SC levels in spring and lower level...

Abstract In pasture-based dairy production systems, identifying the appropriate stocking rate (SR; cows/ha) based on farm grass growth is a key strategic decision for driving overall business. This paper investigates number of scenarios examining effects SR (2–3 cows/ha (0.25 unit changes)), annual nitrogen (N) fertilizer application rates (0–300 kg N/ha (50 kg/ha soil type (heavy and free-drai...

The effect of varying dry matter availability on the conversion of dry matter resources to weight of calf at weaning was evaluated for nine breeds of cattle; Angus, Braunvieh, Charolais, Gelbvieh, Hereford, Limousin, Red Poll, Pinzgauer, and Simmental were recorded for 5 yr. Within each breed, four cows were assigned to each of four feeding levels of dry matter intake: 58, 76, 93, or 111 g of D...

We studied nitrous oxide (N2O) fluxes and soil nitrogen (N) cycling following forest conversion to pasture in the central Amazon near Santarém, Pará, Brazil. Two undisturbed forest sites and 27 pasture sites of 0.5 to 60 years were sampled once each during wet and dry seasons. In addition to soil-atmosphere fluxes of N2O we measured 27 soil chemical, soil microbiological and soil physical varia...

four west african dwarf (wad) grower bucks averaging 6 kg in weight and aged between 5-6 months of age were used in a digestive trial to determine the intake and digestibility of raw or processed pigeon pea seed meal based diets. the diets designated rpbd, spbd, tpbd and bpbd were formulated from cassava peel, palm kernel cake, brewers dry grain, bone meal and common salt to contain 15% of raw,...

The total biomass of a tall fescue (Festuca arundinacea var. Fletcher) pasture was assessed by using a vehicle mounted light detection and ranging (LiDAR) unit to derive canopy height and an active optical reflectance sensor to determine the spectro-optical reflectance index, normalized difference vegetation index (NDVI). In a random plot design, measurements of NDVI and pasture height were com...

1Department of Animal Sciences, NDSU The objectives of this study were to determine the effects of forage inclusion level on growth performance, feeding behavior and carcass characteristics in finishing steers. These results indicate that a decrease in forage inclusion from 20 to 5 percent (dry-matter [DM] basis) in a finishing diet increases dry-matter intake (DMI), average daily gain (ADG) an...

I. Four sheep were given four diets containing proportions of rolled barley and soya-bean meal varied to provide 10.3, 13'3, 16.1 and 19.9 % crude protein in the dietary dry matter; the treatments were given according to a 4 x 4 Latin square design. The mean daily intake was 989 g dry matter. The apparent disappearance of protein, ash, ether extractives and carbohydrate before the abomasum, bet...

the objectives of this study were to determine and compare the chemical composition and ruminal degradability of dry matter (dm), crude protein (cp), neutral detergent fiber (ndf) and acid detergent fiber (adf) of ten pasture forage species dominant in the west provinces of iran. duplicate nylon bags of pasture samples were suspended in the rumen of four wethers for up to 96 h. the chemical com...
