the present experiment was conducted to determine nutritional values of wild pistachio trees (p. khinjuk) leaves it's use it in the diet of sheep. initially chemical composition of p. khinjuk leaf was determined. the diets containing 0, 5, 10, 15, 20, 25 and 30% of p. khinjuk leaf were prepared and used for sheep to determine the best replacement level of it with corn silage. fermentation ...

Twenty-eight (8 with ruminal cannulas) lactating Holstein cows were assigned to seven 4 x 4 Latin squares in a 16-wk trial to study the effects on production and ruminal metabolism of feeding differing proportions of rumen-degraded protein (RDP) from soybean meal and urea. Diets contained [dry matter (DM) basis] 40% corn silage, 15% alfalfa silage, 28 to 30% high-moisture corn, plus varying lev...

vitro digestibility tended to be greater with ammoniation. In the second trial, very high levels of ammonia, urea or glucose were added. Levels of insoluble protein were much higher in this trial than the other. This reflects the high variability of corn silage. Recovery of nitrogen added as ammonia averaged 82 percent while all of the nitrogen added as urea was recovered. The amounts of insolu...

Wheaten straw diets were supplemented with urea or protein (casein or gluten) and offered ad -libitum to sheep. Intakes and digestibilities of the diets were similar irrespective of the nitrogen source. The breakdown of cotton thread suspended in the rumen for 48 h was substantially increased when protein was substituted in the diets. Despite this increase in cellulolytic activity in the rumen ...

the aim of this study was to evaluate the effects of chemical treatments including urea (5%), ammonia (3.5%), calcium hydroxide (4%), sodium hydroxide (5%), sulphuric acid (5%) and hydrogen peroxide (5%) on ph, dm solubility, lignin, silica, phenolic compounds, cellulose and hemicellulose stucture and ruminal degradability of rice straw. after processing, the treated straw was ensiled for 1 mon...

Subacute ruminal acidosis (SARA) continues to be a common and costly metabolic disorder in high-producing dairy cows worldwide. The objective of this study was evaluate if increasing the concentration physically effective neutral detergent fiber (peNDF) diets can reduce risk SARA fed high-concentrate diet. Thirty second-parity Holstein mid lactation (131 ± 8.3 d milk) were randomly allocated 3 ...

This study was designed to determine the effect of physical form and urea treatment of rice straw on rumen fermentation, microbial protein synthesis and nutrient digestibility. Four rumen-fistulated dairy steers were randomly assigned according to a 2 (2 factorial arrangement in a 4 (4 Latin square design to receive four dietary treatments. Factor A was roughage source: untreated rice straw (RS...

The objective of this study was to compare milk production and nutrient utilization in dairy cattle fed silage made from alfalfa (AL) or red clover (RC) versus birdsfoot trefoil (BFT) selected for low, normal, and high levels of condensed tannins. Condensed tannin contents of the 3 BFT silages were 8, 12, and 16 g/kg of DM by butanol-HCl assay. Twenty-five multiparous Holstein cows (5 fitted wi...

Previous research suggested that crude protein (CP) from canola meal (CM) was used more efficiently than CP from solvent soybean meal (SBM) by lactating dairy cows. We tested whether dietary CP content influenced relative effectiveness of equal supplemental CP from either CM or SBM. Fifty lactating Holstein cows were blocked by parity and days in milk into 10 squares (2 squares with ruminal can...

This study was designed to investigate the clinico-haemato-biochemical, rumen fl uid and peritoneal fl uid alteration in buffaloes with peritonitis. Buffaloes with peritonitis had anorexia, dehydration, abdominal distension, ruminal atony, pain, fever, reduced milk yield and loss of defecation. Pungent smelling peritoneal fl uid was yielded on abdominocentesis. Hemato-biochemical alterations re...
