Percentages and yields of fat, crude protein (CP), true protein (TP) and non-protein nitrogen (NPN) wereassessed in milk of four groups of Holstein cows, at early, mid and late lactation (days in milk 20-70, 71-110, 111-150 and 151-210), on a diet rich in concentrates during a hot summer. Four milk samples were taken from individual cows at 10-day intervals. Milk fat percentages were close to b...

nutritive value of rumen epithelial scraping (rep) was assessed using in sacco and in vivo procedures. concentrates were so formulated that 0% (a), 35% (b), 70% (c), and 100% (d) of soybean meal (sbm), were replaced (weight for weight) with rep. in a completely randomized design, 16 west african dwarf (wad) goats were randomly allocated to the experimental diets to assess feed intake and digest...

A total of 360 1-day-old broiler chicks were randomly assigned to 4 treatments with 5 replicate cages and 18 birds per cage for a 35-day trial investigate the effects supplementing Achyranthes Japonica Nakai (AJN) root extract in low crude protein (CP) diet on growth performance carcass traits. Experimental diets divided as standard CP content diet, (LCP) LCP supplemented 0.025 or 0.050% AJN ex...

Sixty Ghezel ewes (age 3.5 years) were used to study the effect of different nitrogenous supplements in flushing ration on reproductive performance. Experimental treatments were divided in five groups: group A: urea; group B: soybean meal (SBM); group C: corn gluten meal (CGM); group D: barley grain and group E: control or basal diet (no flushing). The four flushing rations had nearly the same ...

percentages and yields of fat, crude protein (cp), true protein (tp) and non-protein nitrogen (npn) wereassessed in milk of four groups of holstein cows, at early, mid and late lactation (days in milk 20-70, 71-110, 111-150 and 151-210), on a diet rich in concentrates during a hot summer. four milk samples were taken from individual cows at 10-day intervals. milk fat percentages were close to b...

Expansion of the biodiesel industry has increased the crude glycerin (CG) supply. Crude glycerin has the potential of replacing corn in ruminant diets because the glycerol can be converted to glucose in the liver of ruminants, providing energy for cellular metabolism. The objective was to evaluate the effects of CG with urea, soybean meal, cottonseed meal, and corn gluten feed, respectively, on...

this experiment was carried out to study the effects of corn and green gram intercropping on yield and some quality characteristics of forage at agricultural research station of gorgan during summer 2006 & 2007. the experimental design was a randomized complete block design (rcbd) with twelve treatments and four replications. a local green gram and corn single cross 550 were the crops used in t...

The purpose of this experiment was to evaluate the effects a low-protein diet on selected variables protein and energy metabolism in blood serum as well indicators fermentation faeces (fecal crude protein, ammonia, pH, volatile fatty acids, dry matter). Twelve finishing pigs (initial body weight: 64.6 ± 3.35 kg) were randomly divided into two groups fed basal diets with (CP) levels 13.6% 15.4%,...

The present study evaluates the consequences of a change in pig and poultry protein nutrition through compound feed over time France, on raw materials consumption, economic performances, environmental impacts. It has been conducted using “Prospective Aliments” model by Céréopa, which applies principles linear programming at national scale (France). is based prospective approach. A decrease 1 2 ...
