Milk urea concentration (MU) has been extensively studied and is often used to evaluate energy protein balance in dairy cattle diets, but not this extent goat diets. The aim of study was determine the relationship between MU crude content (CP) diet Alpine goats order reduce excessive nitrogen excretion from organism. For purpose, 72 were randomly divided into three equal groups (24 animals) fed...

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...

The aim of this study was to produce a colloidally stable whey protein concentrate enriched in β-casein. Microfiltration (MF) skim milk completed at ∼7 °C (pore size 0.1 μm) followed by ultrafiltration the MF permeate ∼9 β-casein-whey fraction (BWPC). casein:whey ratio BWPC system ∼25:75. Skim then added retentate level supplying 0, 0.1, 0.3 and 0.5% (w/w) total protein, evaporation spray dryin...

Supplementation of pasta with different protein sources (legumes, milk proteins, egg protein) was done. Cooking and sensory quality of pasta was assessed. Statistically, a nonsignificant variation (P  0.05) was observed in the minimum cooking time of resultant pasta but significant correlations (r=0.95) was obtained between the volume expansion and the percent water absorption of supplemented ...

The proportions of organic feed and roughage in the feed ration for organic dairy cows have to reach 100 and 60%, respectively, in 2005. The aim of this study was to elucidate the long-term effects of reducing or omitting concentrate supplementation to high genetic merit dairy cows on a basal ad libitum diet of clover-grass (silage and grazing). Three concentrate levels, N, L and L1 (38, 0 and ...

The effect of t10,c12-C18:2 on milk production, and fatty acid (FA) profile of milk fat was studied in 8 goats infused duodenally with t10,c12-C18:2 (2 g.10 h-1) during 3 days, followed by a 2-day infusion of skim milk (SM). The goats were assigned to 4 diets in a factorial arrangement constituted by low (L = 45%) or high (H = 65% of the diet DM) percentage of concentrate without (CS0) or with ...

The objectives of this study were to describe the relationships between milk urea concentrations and nutritional management, production, and economic variables in commercial dairy herds. Dairy Herd Improvement (DHI) test-day milk urea data, production data, and information on ration nutrient composition and feeding management programs were collected over a 13-mo period from 53 commercial Ontari...

this study investigated the effect of rumex sc (commercial product which includes of saccharomyces cervisiae, saponin and essential oils) on rumen fermentation, blood glucose, urea, milk yield and milk composition. animals were offered a basal diet containing alfalfa hay (15.5%), corn silage (24%), beet pulp (7%) and concentrate (53.5%). additionally, rumex sc was included in the experimental d...

In this work, pressure-assisted enzymatic gelation was applied to milk proteins, with the goal of enhancing structure and stability pressure-created protein gels. High-pressure processing (HPP) at 600 MPa, 3 min, 5°C concentrate (MPC) samples 12.5% concentration, both in absence presence calf chymosin [up 60 IMCU (international milk-clotting units)/kg milk] or camel (up 45 IMCU/kg milk). Gel ha...

This study was conducted to investigate the nutrient digestibility and lactation performance when alfalfa was replaced with rice straw or corn stover in the diet of lactating cows. Forty-five multiparous Holstein dairy cows were blocked based on days in milk (164 ± 24.8 d; mean ± standard deviation) and milk yield (29.7 ± 4.7 kg; mean ± standard deviation) and were randomly assigned to 1 of 3 t...
