Associative effects of supplementing barley straw diets with alfalfa hay on rumen environment and nutrient intake and digestibility for ewes
The objectives of these experiments were to study the positive associative effects of supplementing barley straw-based diets with different levels of alfalfa hay on nutrient intake, rumen environment, and nutrient digestibility and to evaluate the minimal amount of alfalfa hay needed to produce such an effect in ewes. In experiment one, 15 Awassi ewes (®ve ruminally ®stulated; body weight 54 ...
متن کاملSubstituting oat hay or maize silage for portion of alfalfa hay affects growth performance, ruminal fermentation, and nutrient digestibility of weaned calves
OBJECTIVE The impact of forage feeding strategy on growth performance, ruminal fermentation and nutrient digestibility in post-weaning calves was investigated. METHODS Forty-five female Holstein calves (body weight [BW] = 79.79±0.38 kg) were enrolled in the 35-d study at one week after weaning and randomly assigned to one of three dietary treatments. All diets were fed as total mixed ration c...
متن کاملEffect of feeding macerated alfalfa silage on nutrient digestibility and milk yield in lactating dairy cows.
Five feeding studies were conducted with 141 lactating Holstein cows comparing macerated and control alfalfa silage harvested at two cuttings in each of 2 yr. Overall, silage made from macerated alfalfa contained more ash (suggesting improved soil contamination); greater fiber and lower nonprotein nitrogen (NPN) content suggested greater fermentation in the silo. In a digestion study, two diets...
متن کاملEffect of Heat Treating Alfalfa Hay on Chemical Composition and Ruminal In Vitro Protein Degradation
Conventional (unshredded) and shredded alfalfa hays were heated in either a forced-air oven or a steam pressure cooker at different times and temperatures to determine the effect of heat treatment on chemical composition and ruminal protein degradability. Rates of protein degradation and extents of protein escape were estimated using a ruminal inhibitor in vitro system. Both rates and extents w...
متن کاملeffect of alfalfa fluffers on drying rate, baling loss, and nutrient value of alfalfa during baling
in this study, the performance of a fabricated fluffer was evaluated and compared with common field curing methods for alfalfa. the drying rate, baling loss and alfalfa nutrient value (dry matter and crude protein) were the criteria for evaluation. the alfalfa was cut using a mower-conditioner. a randomized complete block experimental design was used with three treatments (fluffing swathed alfa...
