The result shows that the rations of lucerne hay with large proportion(lucerne=24%DM)and lower ratio of concentrate to roughage(40:60)can significantly increase the fat percentage of milk;
60 China Holstein Cows were allocated to 4 rations which have different levels in lucerne hay and grain concentrate : roughage ratio,to examine the effect of formulas on milk yield,fat percentage and economic benefit.
60 China Holstein Cows were allocated to 4 rations which have different levels in lucerne hay and grain concentrate:roughage ratio,to examine the effect of formulas on milk yield,fat percentage and economic benefit.
The trial results indicated that larger content of alfalfa hay(24%DM) and lower concentrate to roughage ratio(40:60) gained higher(<0.05)or highest(<0.01) fat percentage of milk;
60 China Holstein Cows were allocated to 4 rations which have different levels in alfalfa hay and grain concentrate to roughage ratio to examine the effect of formulas on performance and economic benefit and to find first-rank formula.
3. P fertilizer adversely affected alfalfa total dry weight. And yield decreases ranged from 2.53-16.4% in cut 1 and 2.41-24.94% in cut 2. Except for P single applied, alfalfa yield increases all took place in other treatments.
The results showed that there was significant positive correlation between yield and climatic factor and the direct effect of three climatic factors on its yield was as follows: accumulated temperature of above 5 ℃>sunshine hour>precipitation;
When fed high-quality chopped lucerne hay, young-at-foot (YAF) kangaroos, which have permanently left the mother's pouch but are still sucking, and recently weaned red kangaroos had digestible energy intakes of 641±27?kJ kg-0.75
Sixteen male growing sheep, received a basic diet with: 42% hydrolyzed sugarcane bagasse (HSB), 45% lucerne hay (LH) plus 14% hydrolyzed sugarcane bagasse, and 30% citrus pulp (CTP) plus 40% hydrolyzed sugarcane bagasse.
The ratio of DMI to water intake decreased (p>amp;lt;0.01) due to water restriction but increased (p>amp;lt;0.01) with Lucerne hay compared to grass hay.
Most probable number (MPN) estimates indicated that a mean of 4.3×107 and 5×106 bacteria per ml of rumen fluid from a predominantly alfalfa hay-fed steer demethoxylated ferulate and syringate, respectively.
We tested these predictions by measuring digestion and retention of a grass hay and an alfalfa hay, forages that exhibited contrasting rates and extents of cell wall digestion.
