introduction: sugarcane (saccharum officinarum) is widely cultivated in south west of iran for production of sugar. after harvest, a lot of sugarcane tops remain on the farm that can be used to feed ruminants. the total digestible nutrients (tdn) and crude fiber of sugarcane top is about 72% and 39%, respectively. the digestibility of dry matter (54%) and crude protein (39%) of sugarcane top is...

samples of grass pea seed (lathyrus sativus) were prepared and analyzed for some chemical composition and as well for their anti-nutritional factors. the rumen degradability coefficients and post ruminal digestibility of dry matter and crude protein of unheated vs. oven heated samples were determined, employing in situ and in vitro techniques. results indicated that grass pea seed contained a c...

A digestibility trial was conducted to evaluate the nutritive value of diets composed of either Cambodian full-fat rubber (Hevea brasiliensis) seeds or soya beans using 16 Mong Cai*Large White pigs. Rubber seeds of unknown falling day and storing period, and extruded soy beans were used in this study. Water spinach (Ipomoea aquatica) was given ad libitum as a complementary protein-rich foliage ...

two experiments were conducted to evaluate the crude protein fractionation, in vitro gas production and the biological effects of tannins in alfalfa silage treated with different levels of pistachio by-products (pb) extract. pb was soaked in water with a ratio of 1:5 (w/v) for 12 h. after filtering and concentrating, the crude extract was added to fresh alfalfa to a final concentration of 1%, 2...

a feeding trial of 120 days duration was conducted to study the effect of replacing 20 and 25 % of camel ration by poultry litter (pl) on the performance and some blood biochemical parameters. fifteen healthy one–humped camels were allotted into three groups (5 animals / group). the first group was fed a basal ration and considered as control, while the second and third groups were fed rations ...

Two groups of eight Friesland bull calves each were used in the trial. Calves received a commercial, coagulable milk replacer in which casein coagulation either was normal (CM treatment), or was prevented by the precipitation of Ca++ with an oxalic acid-sodium hydroxide buffer (NCM treatment). In both treatments, the daily milk replacer feeding level (percentage of birth mass) was increased fro...

Microbial protein synthesis of steers (liveweight 286±9 kg) was compared with diets of ad libitum winter grass and fodder beet with 1 kg DM of lucerne silage. The experimental design was a four-by-two treatment comparison (experiment 1 and 2), using 11 day individual pen trials with total faecal and urinary collection. The trials assessed in vivo digestibility of diets, and diurnal variations i...
