Diets contained corn silage, alfalfa silage, and wheat straw as forage sources; HS contained 32% starch, 3.2% FA, and 25% neutral detergent fiber, whereas HFF contained 16% starch, 5.4% FA, and 33% neutral detergent fiber.
This study was designed to evaluate lactational responses of cows fed corn silage (CS) or alfalfa silage (AS) as primary forage source when the diet was balanced for recommended (RP) or excessive (HP) amounts of rumen degradable protein (RDP) and undegradable protein (RUP) according to the recommendations of the National Research Council NRCC).
Overall, based on N utilization as well as milk production, 17% protein in diets utilizing various proportions of alfalfa and corn silage as the forage source appeared sufficient for cows producing 38 kg/d of milk in this study.
At the first trial, alfalfa hay was used as a forage source whilst in the second trial, corn silage was used as a forage source.
Experimental diets (500 500 forage to concentrate ratio; dry matter (DM) basis) were used in a 2×2 factorial design using either chopped grass hay or whole crop barley silage as the forage source with or without ground linseed at 150 g/kg ration DM as a partial replacement for barley grain.
These results demonstrate the potential for mulberry as a strategic forage source in temperate as well as tropical regions of the world.
Pea silage can replace barley or alfalfa silage as a forage source for dairy cows in early lactation.
The importance of wild plants as alternative forage source for pollinators was assessed by a survey of the flowering plants in different habitats surrounding eggplant fields.
Cows were fed total mixed diets containing corn silage (CS), 50% corn silage and 50% alfalfa hay (CSAH), or alfalfa hay (AH) as the forage source.
This study was conducted to examine the effects of dietary energy source and level on intake, digestion, rumen microbial protein synthesis, and milk production in lactating dairy cows, using corn stover as a forage source.
