Sixteen periparturient Holstein cows calving during summer and autumn were fed to meet maintenance plus last 2 month of gestation level of TDN (MP) and 1.2 time of MP level (HMP). Dry matter intake of cows fed at HMP level during summer and autumn decreased by 1 and 2% of the offered feed in 1 week prepartum, respectively, and cows fed at MP level consumed all of the offered feed. Rectal temperatures at 08 : 30 h of cows fed at HMP level were higher than those of cows fed at MP level. Blood hematocrit and hemoglobin of cows increased during summer and were higher for cows fed at HMP level. Plasma total protein and glucose of cows during summer were higher than those during autumn, and the increased feed intake elevated plasma total protein and glucose. Plasma urea-N of cows fed at MP level was higher than that of cows fed at HMP level during autumn. The increased feed intake decreased plasma nonesterified fatty acid of cows during summer and autumn. These results suggest that blood components of periparturient cows are altered by calving season and feeding level.
Equal number of red jungle fowl (JF) and commercial broiler chickens (CB), raised in battery cages, were provided a single complete diet (control) or a choice of a complete diet, ground corn and ground soybean from 21 to 56 days of age. There were significant genotype ${\times}$ feeding regimen interactions for several traits measured suggesting CB and JF responded differently to the two feeding regimens. The single fed CB had better growth and feed conversion ratios (FCR) than those under choice feeding. However, the body weight and FCR of JF were not affected by feeding regimen. While the single fed and choice-fed JF consumed similar amount of protein during days 21 to 55, the protein intake of the choice-fed CB was lower than the control. From days 21 to 55, irrespective of genotype, choice-fed chicks consumed less energy than their single fed counterparts. Regardless of genotype, the trend in the proportion of each feed consumed was similar with complete diet>corn>soybean. In conclusion, while choice-fed JF were capable to select nutrient necessary for maximum growth, choice feeding was detrimental to growth and feed conversion ratio in CB.
The surveys of food intakes were carried out on 49 healthy infants aged 4-9 months at the first interview and repeated 3 more times at the interval of 2 months by using food diary recorded by their mothers. Of the subjects 12 were breast-fed, 28, formula-fed, and 9, mixed type-fed. Foods introduced first as the weaning food were commercial weaning foods, fruit juices, yoghurt, egg and rice. Supplemental food was introduced at the age of 4 months in 57% of the infants, but it amounted to a significant proportion of overall food consumption from the age of 6 months. The levels of nutrients except energy, iron and niacin were similar or in excess of RDA, and breast-fed infants tended to have lower intakes of energy and protein compared to infants formula-fed or mixed type-fed. Average intakes of vitamin A, vitamin B1, vitamin B2, vitamin C and calcium were above RDA, but iron intake did not meet RDA of infants of all ages. In conclusion, the average status of nutrient intakes of infants was fairly good, however, food consumption besides milk was less in breast-fed infants than in formula-fed infants, and iron status seemed to be poor, Although it is well-known that breast-milk compared to formulas is more beneficial for infants, mothers feeding breast-milk to their infants should be educated for the importance of supplemental food and its practice to support good nutrition.
This study was divised to observe the effects of defatted(by petroleum ether) Korean ginseng on the cholesterol level of Sprague-Dowley Albino male rats by alternating the diet. 130 heads of weaned rats having 83$\pm$4g of body weight were fed with each stock diets supplemented with 0.5, 1.0 and 3.0% defatted ginseng powder for 4 or 8 weeks, and after that fed with stock diet only for 8 or 4 weeks. Total cholesterol and free form cholesterol contents in serum, liver and aorta of them were determined, and compared with the each corresponding group which was fed with defatted ginseng control diet for 12 weeks. Total cholesterol and free form cholesterol contents in the serum were increased caused by the alternating diets which was fed on 0.5, 1.0 and 3.0% defatted ginseng diet for 4 and 8 weeks after being fed on stock diet for 8 and 4 weeks, conversely total cholesterol contents in the aorta were decreased by the same alternating diets. Free form cholesterol contents in the serum, liver and aorta of the group which was fed on 1.0% defatted ginseng diet 8 weeks after being fed on stock diet for 4 weeks were increased, but that of the group which was fed alternately on 3.0% defatted ginseng diet were decreased than the corresponding defatted ginseng control diet group.
A 6-week feeding trial was conducted to investigate effects of dietary supplementation with wood vinegar (WV) as a feed additive for juvenile olive flounder, Paralichthys olivaceus. Eight experimental diets supplemented with 0(control), 0.01, 0.025, 0.05, 0.1, 0.25, 0.5 and 2.0% WV/kg diet($WV_0,\;WV_{0.01},\;WV_{0.025},\;WV_{0.05},\;WV_{0.1},\;WV_{0.25},\;WV_{0.5},\;and\;WV_{2.0}$, respectively) were prepared by mixing with basal diet. After the 6-week feeding trial, fish fed the $WV_{0.1}$ diet had significantly higher weight gain, feed efficiency, and specific growth rate than those of fish fed the other diets(P<0.05). No mortality was observed in the treatment groups fed the experimental diets for 6 weeks. The liver antioxidant activity of fish fed the $WV_{0.01},\;WV_{0.025},\;and\;WV_{0.05}$ diets was significantly higher than that of fish fed the other diets. The lysozyme activity of fish fed the $WV_{0.25}$ diet was significantly higher than that of fish fed the other diets. Fish fed diets supplemented with WV had significantly lower cumulative mortality than that of fish fed the control diet throughout the challenge test, and fish fed the $WV_{0.05}\;and\;WV_{0.1}$ diets had the highest resistance to disease caused by Edwardsiella tarda at day 7 of the challenge test. Therefore, feeding 0.05-0.1% WV/kg diet improves the growth and immune responses of juvenile olive flounder, Paralichthys olivaceus.
Two experiments were conducted to evaluate the effect of processing and method of ensiling on the digestion and utilization of high moisture barley (HMB) in cattle. In experiment 1, four Holstein heifers were assigned in a Latin square design to diets containing 70% barley, 25% alfalfa hay and 5% supplement on a dry matter (DM) basis. Diets differed only in the type of barley fed: rolled dry barley (R-DB), rolled HBM (R-HMB), ground HMB (G-HMB) or unprocessed HMB (U-HMB). In experiment 2, three Holstein steers were fed 85.2% barley, 10.2% whole plant barley silage and 4.6% supplement on a DM basis. Again, diets differed only in the type of barley fed: R-DB, rolled HMB from a pit silo (Pit-HMB) or rolled HMB from a Harvestore silo (HAV-HMB). In experiment 1, digestibility coefficients for animals fed R-HMB were significantly higher than observed for U-HMB. While not significant, a similar trend for decreased digestibility was observed for R-DB and G-HMB. Animals fed HMB had significantly lower ruminal propionate concentrations. In addition, the rate of degradation of the degradable DM and crude protein (CP) fractions was slower for HMB than for dry barley. In experiment 2, a trend to lower digestibility coefficients was observed for animal fed R-DB compared to those fed Pit-HMB or HAV-HMB. Ruminal propionate concentrations for animals fed R-DB also tended to be higher than for those fed the HMB diets. Dry matter and CP disappearances from nylon bags was substantially lower for Pit-HMB than for R-DB or HAV-HMB. The results suggest that replacement of dry barley by rolled or unprocessed HMB in the diet of animals fed high grain diets may contribute to a more stable rumen environment.

The present experiment was conducted to evaluate the effects of feed processing and feeding methods on growth performance and carcass characteristics of growing-finishing pigs. A total of 72 pigs (LYD, 22.24 kg BW) were employed for a 90-d feeding trial. Treatments were 1) mash dry feeding (MD), 2) mash wet feeding (MW), 3) pellet dry feeding (PD), and 4) extruded pellet dry feeding (EPD). Corn, soybean meal and wheat bran in the basal diets were extruded before mixing and pelleting for EPD diet production. Ileal or fecal digestibility and carcass traits including lean meat percentage and weights of stomach ulcer were also examined. During the growing period, pigs fed PD showed improved (p < 0.05) average daily gain (ADG) and feed conversion (F/G) over those fed MD, whereas no significant differences in average daily feed intake (ADFI) were found among dietary treatments. Finisher pigs fed MD showed lover, but not significant, ADG and F/G than those fed MW, PD or EPD. For the overall period, pigs fed PD grew faster (p < 0.05) than those fed MD or EPD. Feed intake was different between the two feeding methods (MD vs MW), and between the two processed feeds (PD vs EPD). The digestibility of crude fat was higher (p < 0.05) in pigs fed EPD than in pigs fed mash feeds. NFE digestibility of EPD treatment was also higher (p < 0.05) than that of PD. Back fat (10th rib area) was thicker (p < 0.05) tn pigs fed MD than in pigs fed EPD. other carcass traits including incidence of esophagogastric ulcers were not different among treatments. In conclusion, pelleting appeared to bo the desirable processing methods and wet feeding could also be recommended for growing-finishing pigs.

In this study, dietary supplementations of Korean Meju, fermented soybean meal (F-SBM) by Aspergillus oryzae, and A. oryzae itself were evaluated on growth performance, feed utilization, immune responses and phosphorus availability in juvenile parrot fish, a marine aquaculture fish species. Four isonitrogenous and isocaloric diets were formulated to contain 8% soybean meal (control diet), 4% Meju (50% soybean meal was replaced by Meju), 4% F-SBM (50% soybean meal was replaced by F-SBM), or 0.08% A. oryzae itself. One of the four experimental diets was fed to triplicate groups of fish for 8 weeks. At the end of the feeding trial, no significant differences were found in growth performances and feed utilization. Red blood cell counts in the fish fed the A. oryzae diet were significantly higher than that of fish fed the control diet. The antioxidant activity in Meju diet was significantly higher than that of the control and A. oryzae diets. Fish fed Meju and F-SBM diets showed numerically higher antioxidant activity of serum compared to that of fish fed the control diet, even though it was not significant. Liver superoxide dismutase activity of fish fed the test diets was significantly higher than that of fish fed the control diet. The apparent digestibility coefficients of protein of fish fed all the diets were not significantly different. Phosphorus absorption was numerically increased in fish fed F-SBM and A. oryzae diets compared to that of fish fed the control diet. This study indicates that the fermentation process of soybean meal does not impair growth performance and feed utilization in parrot fish. The fermentation process could enhance the availability of phosphorus in soybean meal and non-specific immune responses of parrot fish.

An experiment was conducted to study the performance of broilers chicks (2 to 42 d of age) fed diets containing pearl millet (PM, Pennisetum typhoides), foxtail millet (FOM, Setaria italica) or finger millet (FIM, Elusine coracana) totally replacing (w/w) yellow maize (YM) with and with out supplementing non-starch polysaccharide (NSP) hydrolysing enzymes at the rate of 0.5 g/kg diet. Enzyme preparation contained amylase 2,400 units, hemi-cellulase 5,400 units, cellulase 12,000 units, protease 2,400 units and beta-glucanase 106 units/g. Each diet was fed to eight replicates (five female Vencob broilers/replicate) housed in stainless steel battery brooders. The estimated metabolizable energy (ME) contents of YM, PM, FOM and FIM were FM (PM) were about 3,389, 2,736, 3,303 and 2,846 kcal/kg, respectively. Total replacement of YM with FOM did not influence the body weight gain, ready to cook yield, relative weights of giblet, liver, intestine, lymphoid organs (bursa and spleen) and length of intestine, antibody titers and livability at 42 d of age. But the food efficiency decreased significantly in FOM fed broilers compared those fed YM. Further, the fat content in thigh muscle reduced with FOM fed groups compared to those fed YM. The performance of broilers decreased significantly in PM and FIM fed broilers compared to those fed YM. The relative weights of giblet, gizzard and liver increased in FIM fed groups compared to those fed YM as the principal source of energy in broilers. Incorporation of NSP hydrolysing enzymes in commercial broiler diets improved the efficiency of feed utilization during starter phase but not at 42 d of age. The results thus indicate that yellow maize can be replaced in toto on weight basis in commercial broiler diets without affecting the performance. Supplementation of NSP hydrolysing enzymes was beneficial in enhancing feed utilization during the starter phase.

Thirty early lactating Nili-Ravi buffaloes, six animals in each group, were used in a completely randomized design to examine the feeding value of 4% urea treated wheat straw (UTWS) ensiled with 6% or without acidified molasses. Five experimental diets were formulated. The control ration was balanced to contain 30% DM from UTWS ensiled without acidified molasses. The other four diets were formulated to have 30, 40, 50 and 60% DM from UTWS ensiled with 6% acidified molasses, respectively. Dry matter and neutral detergent fiber (NDF) intakes were higher in buffaloes fed diets containing UTWS ensiled with acidified molasses compared with those fed a diet containing UTWS ensiled without acidified molasses. Intake of DM was not significantly different in buffaloes fed diets containing varying levels of UTWS ensiled with acidified molasses. A similar trend was observed for crude protein (CP) intake. Apparent DM and NDF digestibilities were significantly higher in buffaloes fed diets containing UTWS ensiled with acidified molasses compared with those fed UTWS ensiled without acidified molasses. However, differences in DM and NDF digestibilities were non-significant across buffaloes fed diets containing varying levels of UTWS ensiled with acidified molasses. Milk yield (4% fat corrected) was significantly higher in buffaloes fed diets containing UTWS ensiled with acidified molasses than those fed a diet containing UTWS ensiled without acidified molasses. Milk yield was similar in buffaloes fed varying level of UTWS ensiled with acidified molasses. Milk CP, true protein, solid-not-fat and total solids were similar in buffaloes fed UTWS ensiled with or without acidified molasses. The UTWS ensiled with 6% acidified molasses can be included at up to 60% DM of lactating buffalo rations without any ill effect on productivity.
