Nutritional Value of Eastern Gamagrass Hay Compared with Alfalfa Hay
نویسندگان
چکیده
A feeding trial utilizing lactating dairy cows was conducted to compare Eastern gamagrass (Tripsacum dactyloides) and alfalfa hay. Response criteria included feed intake, weight change, and yield and composition of milk. Dry matter intake and milk yield of cows fed alfalfa hay exceeded that of those fed gamagrass hay. There was no significant difference in milk composition, and average weight change was positive and similar for the two groups of cows in the feeding trial. Even under conditions where the lower protein content of gamagrass hay was compensated for by feeding a grain mix with a higher protein percentage, it was not equal to alfalfa hay as a forage source for lactating dairy cows.

متن کاملNeutral Detergent Fiber (NDF) and its Role in Alfalfa Analysis
The key chemical analysis used to estimate the energy value of alfalfa hay for trading purposes, ADF (acid detergent fiber), has been supplanted by NDF (neutral detergent fiber) as the key chemical analysis used by nutritionists to evaluate the fibrosity and energy value of alfalfa hay for nutritional purposes. It is important that the alfalfa hay trading industry abandon ADF, as it will genera...

The purpose of this study was to determine the chemical composition and comparing the in vitro fermentation parameters of banana peel (BP) with wheat straw and alfalfa hay. Thereafter, BP was added at levels 0, 50, 100, 150 or 200 g/kg dry matter (DM) at the expense of dietary hay. Banana peel had higher crude protein (CP) content compared to wheat straw, but it was lower than alfalfa (P<0.05)....
متن کاملWhat Are Dairy Nutritionists Looking for in Alfalfa Hay
Dairy cattle nutritionists value alfalfa hay for its high energy value which supports milk production, its rapidly rumen digested structural fiber which stimulates feed intake, its coarse structural fiber that stimulates ruminative chewing and salivation which results in rumen buffering, its structural fiber which has a high buffering capacity , its high protein level which supports animal prot...
متن کاملAre There Unique Features of Alfalfa Hay in a Dairy Ration?
Alfalfa hay is, or should, be highly valued as a dairy cattle feed due to its relatively high (for a forage) crude protein (CP) level which has a low rumen soluble fraction and a relatively high rumen escape fraction which contains a high level of the key amino acid lysine. It should also be valued for its high level of rapidly rumen digested pectin which has a high cation exchange capacity (CE...
