Nitrogen effect on Nodulation of Alfalfa (Medicago sativa L.) and Sainfoin (Onobrychis vicilifolia Scop.)
Biological Nitrogen fixation is one of the two sources of nitrogen (N). Most nitrogen fixation in agriculture takes place in the Fabaceae family which can form symbiotic relationships with Rhizobium spp. if it is present in the soil. This study reexamines the effect that nitrogen (N) application has on nodulation number on the rooting zone of two small seeded legumes, alfalfa (Medicago sativa L...
متن کاملEffect of dietary crude protein level and degradability on ruminal fermentation and nitrogen utilization in lactating dairy cows.
The objectives of this experiment were to investigate the effects of two ruminally degradable protein (RDP) levels in diets containing similar ruminally undegradable protein (RUP) and metabolizable protein (MP) concentrations on ruminal fermentation, digestibility, and transfer of ruminal ammonia N into milk protein in dairy cows. Four ruminally and duodenally cannulated Holstein cows were allo...
متن کاملEffect of steroidal sapogenins on ruminal fermentation and on production of lactating dairy cows.
Supplementation of dairy rations with steroidal sapogenins was evaluated in an in vitro, an in situ, and a production trial. Sixteen in vitro semicontinuous rumen cultures were supplied a 55:45 concentrate to roughage substrate with Sarsaponin concentrations of 0, 33, 55, and 77 ppm of air-dry feed for 22 d. Supplementation decreased protozoa numbers and increased bacterial numbers and acid det...
متن کاملLotus Corniculatus and Condensed Tannins – Effects on Milk Production by Dairy Cows
Birdsfoot trefoil (Lotus corniculatus) increases milk yield of dairy cows. An indoor feeding experiment using Friesian dairy cows in mid lactation was conducted to determine what proportions of the milk yield and composition changes were due to the condensed tannins (CT) in Lotus, and what proportions were due to factors associated with legumes (higher herbage intake and forage quality). Cows w...
متن کاملEffect of processing whole cottonseed on nutrient digestibility and ruminal fermentation in dairy cows*
Four ruminally cannulated Holstein cows were used in a 4 × 4 Latin square design to determine the effect of feeding linted, delinted and extruded linted whole cottonseed (WCS) on nutrient digestibility and ruminal fermentation. Result showed that crude protein digestibility was lower in linted and delinted WCS treatments than control and extruded linted WCS treatment. Cows fed extruded delinted...
