The objective of this study was to examine whether feeding induced hypovolemia (decrease in plasma volume) acts on the regulation of feed intake in goats fed on dry forage. In order to prevent feeding induced hypovolemia, a 2 h intravenous infusion (16-18 ml/min) of isotonic mannitol solution was begun 1 h prior to feeding and continued until 1 h after the start of the 2 h feeding period. The intravenous infusion of isotonic mannitol solution (MI) decreased plasma osmolality by 1.0%, plasma total protein concentration by 4.2% and hematocrit by 5.9%, respectively. In comparison with no infusion (NI), MI significantly decreased thirst level by approximately 13%. At the completion of the 2 h feeding period, cumulative feed intake had been increased by 43% by MI. In conclusion, feeding induced hypovolemia in goats fed on dry forage increased thirst level more than the increase in plasma osmolality did. The results demonstrate that feeding induced hypovolemia is one of the factors controlling feed intake in goats fed on dry forage.

This study was carried to develop the new material of functional food which antioxidant of natural substances of sprouts. We compared antioxdiative activity and antioxidant substances exist in sprouts. Antioxidaive activities of sprouts were measured by total polyphenolic acid contents, electron donating activity(EDA), SOD-liked activity and hydroxyl radical scavenging ability. Total polyphenolic acid content was very higher in Rape sprouts extract(Rap) than other sprout extracts. Also Rape extract was showed the most excellent antioxdiative activity in SOD liked activity at 86.94%. The EDA was ordered Rape sprouts extract(Rap)>Tatsoi sprouts extract(Tat)>Broccoli sprouts extract(Bro)>Alfalfa sprout extract(Alf). Hydroxy radical scavenging ability was the most effective in Rape sprouts extract(Rap). Therefore we could be certain that Rape sprouts extract(Rap) was the most effective in antioxidative activity from sprouts.

Fifty mid-lactation Holstein cows were used in a six-week feeding trial to study effects of high-forage, and high-fat diets on blood constituents, rumen fermentation and dry matter digestibility. Cows were divided into 10 replicates, each consisting of five cows. Each cow was assigned to a control (diet 1) or one of the four experimental diets (high-forage (75%), high-fat (7.5%) (diet 2); high-forage. medium-fat (5.0%) (diet 3); medium forage (65%), high-fat (diet 4); medium-forage, medium-fat (diet 5)), or a control diet containing about 50% forage and 2% fat. All diets were isonitrogenous (17.7% crude protein). The forage mixture consisted of 20% alfalfa hay, 40% alfalfa haylage, and 40% corn silage. Supplemental fat included 80% rumen-protected fat and 20% yellow grease. A non-significant difference was observed in concentrations of blood glucose for cows on different experimental and control diets. Plasma nonesterified fatty acids (NEFA) were higher in cows consuming experimental diets than those consuming the control diet. However, differences in NEFA concentrations in the plasma of cows consuming diets with different forage and fat levels were not significant. Rumen pH, concentration of volatile fatty acids (VFA) in rumen contents, and dry matter digestibility of control and experimental diets, and diets with different levels of forage and supplemental fat did not differ significantly.

Experiment was conducted to study the effect of sources of dietary fiber on the intestinal morphology of geese. Sixty white Roman geese of two-week-old were divided randomly into six groups and were fed with isoenergetic and isonitrogenous diets which contain alfalfa meal, barley hull, rice hull, purified cellulose, lignin, or pectin as the major dietary source of fiber. Different sources of dietary fiber significantly influenced the villi height and the crypt depth in the duodenum, and the villi height and the muscle layer thickness in the ileum (p < 0.05). The duodenal villus in the geese that fed diets with alfalfa meal, rice hull or pectin supplemented were significantly longest ($968.5{\mu}m$), whereas the lignin group was significantly shortest villus and deepest crypt depth (p < 0.05). The thicknesses of the ileal and caecal muscle layer were significantly thicker in the geese fed with cellulose supplemented diets than in those fed with the other treatment diets. The caecum of the barley bran fed geese possessed significantly longest villi and the most thick muscle layers (p < 0.05). From scanning electronic microscopic observation, the leafy and plate-like in the duodenal villi morphology of geese represented a more effective nutrient absorption in the small intestine. The morphology of ileal villi in geese was similar from herbivorous rabbit and from the African Green monkey.

A study was conducted to estimate nutritive value of forage sources used in deer diets. Bags containing feedstuffs were incubated four times for periods up to 72 hours in two chemostats filled with ruminal fluid from deer or cattle. Parameters estimated were water-soluble and $65{\mu}m$ filterable plus insoluble digestible fractions(No. = 4) and extent of disappearance(No. = 8) of feed neutral detergent fiber(NDF). Among tested feeds, the ranking of values of these parameters were soybean hulls > alfalfa pellets > corn cobs or rice straw > cottonseed hulls or rice hulls > sawdust, indicating that soybean hulls and alfalfa pellets were more fermentable than other agricultural residues. It is possible to utilize variability among tested feeds of fraction, disappearance rate and (or) extent of DM and NDF when these feeds are used as roughage sources in deer diets.
