Maximizing milk yield without impairing host health is a great challenge for dairy industry. However, the high concentrate feeding often unavoidably increases the risk of Subacute ruminal acidosis (SARA) in dairy cows, characterized by periodic episodes of low ruminal pH. The economic costs caused by SARA are enormous, while its pathogenesis is not very clear. As the first and the main digestiv...

background and objective : mozzarella is a soft cheese belonging to the pasta filata family, containing 18-24 % fat. the objective of this study was to determine the effect lowering mozarella fat content to 6% and adding whey protein concentrate on the rheological properties of the low-fat cheese. materials and methods : low-fat mozzarella was produced using 3 fat replacers ( dairy-lo, 35% prot...

preparations of platelet concentrates (pcs) that are stored under blood bank conditions and used for transfusion purposes, appear to be enriched in platelet derived-microparticles (pmps) with high coagulant activity that may change platelet efficacy and safety issues. high shear stress could cause shedding of pmps from the platelet plasma membrane, platelet aggregation, and activation of the co...

A replicated randomized block trial was conducted to determine the response of Holstein cows rotationally grazing annual ryegrass-Crimson clover pasture to supplemental concentrate. Within each of 2 yr, 16 Holstein cows were assigned to one of four blocks by energy-corrected milk yield, days in milk, and parity. Treatments included one of four levels of concentrate based on the following grain ...

In Trial 1, 12 wether lambs (34.2 +/- .8 kg BW) were used to determine the effects of restricting intake of diets increasing in percentage of concentrate, to achieve isoenergetic intakes, on digestibility and N metabolism. The trial consisted of two 14-d periods, 9 d for adaptation and 5 d for total collection of urine and feces. Treatments were 22, 39, 61, and 92% concentrate diets fed at ad l...

In the process of cyanidation gold concentrate from a smelting company, content copper and zinc in liquid gradually increased. production, acidizing is used to treat lean solution high concentrate, mixed products containing copper, other metals are produced. this paper, pH value precipitation 6.0 3.0 through theoretical calculation experiment. The separation realized successfully. product with ...

Fifty-six mature Polypay ewes were used in two experiments to examine the effects of feeding a high-grain diet at a restricted intake on milk production and composition, lamb performance and out-of-season breeding. Ewes were fed either a high-grain diet (85% concentrate and 15% forage) or a high-forage diet. The high-forage diets were 68% forage and 32% concentrate in Experiment 1 and 80% forag...

Forty-eight bulls (335 +/- 8.6 kg of initial BW) were randomly assigned to 4 glycerin levels (0, 4, 8, and 12% of concentrate DM) with the objective of evaluating the effects of glycerin supplementation on performance, ruminal fermentation, metabolism, and carcass and meat quality in Holstein bulls fed high-concentrate diets. Concentrates were formulated to be isonitrogenous and isocaloric (ass...
