Effect of feeding pistachio by-products silage supplemented with polyethylene glycol and urea on Holstein dairy cows performance in early lactation
TL;DR: In this paper, the effect of feeding pistachio by-products silage with or without supplementation of polyethylene glycol (PEG) and urea on intake, apparent total digestibility, ruminal fermentation and performance of dairy cows was evaluated.
Journal ArticleDOI
Effect of mineral salts, carbachol, and pilocarpine on nutrient digestibility and ruminal characteristics in cattle.
TL;DR: Fifty percent concentrate diets containing 2% sodium bicarbonate, sodium chloride, or no additional mineral salts were fed to three barren Holstein cows fitted with ruminal fistulas to increase ruminal pH, liquid volume, liquid dilution rate, and particulate rate of passage.

Reducing crude protein and rumen degradable protein with a constant concentration of rumen undegradable protein in the diet of dairy cows: Production performance, nutrient digestibility, nitrogen efficiency, and blood metabolites
TL;DR: To improve the efficiency of N utilization by early-lactation dairy cows, 9.3% RDP in rations provides adequate protein to optimize milk production while minimizing N excretion in urine when the amounts of lysine and methionine and theLysine to methionines ratio are balanced with sufficient dietary RUP.

Effects of Radix Bupleuri extract supplementation on lactation performance and rumen fermentation in heat-stressed lactating Holstein cows
TL;DR: In this article, the effects of RBE supplementation on lactation performance and rumen fermentation in Holstein cows under heat stress were investigated, and it was shown that supplemental RBE at 0.25, 0.50 and 1.5 g/kg could mitigate the negative effects of heat stress on production in lactating Holstein cow.

Apparent digestibility of mediterranean forages determined by total collection of faeces and acid-insoluble ash as internal marker
TL;DR: In this article, the acid-insoluble ash (AIA) was used as an internal marker to determine the apparent digestibility rate of Mediterranean forages in the French nutritive value tables of feeds for horses.
