This study was conducted to investigate the effects of fishmeal replacement with acid-concentrated soybean meal (ACSBM) on growth performance, blood biochemistry, and ingredient digestibility in juvenile olive flounder Paralichthys olivaceus. Six experimental diets were formulated to replace fishmeal protein with ACSBM at 0%, 20%, 30%, 40%, 50%, and 60% (designated ACSBM0, ACSBM20, ACSBM30, ACSBM40, ACSBM50, and ACSBM60, respectively). Triplicate groups of fish (initial fish mean weight: $14.3{\pm}0.03g$) were fed the experimental diets to apparent satiation (twice daily at 08:00 and 18:00 h). After a 12-week feeding trial, a total of 180 healthy fish were randomly distributed into three Guelph system tanks at a density of 60 fish/tank (initial fish mean weight : $50.6{\pm}2.4g$) to test the apparent digestibility coefficients of the ingredients (ACSBM, fishmeal, and soybean meal). Although negative effects were observed with ACSBM40, ACSBM50 and ACSBM60 after 12 weeks of feeding, up to 20% of the fishmeal protein could be successfully replaced with ACSBM without significant growth depression. Hemoglobin and hematocrit values of fish fed the ACSBM50 and ACSBM60 diets were significantly lower than those of fish fed the ACSBM0 diet. Glucose values of fish fed the ACSBM60 diet were significantly higher than those of fish fed the ACSBM0 and ACSBM20 diets. Digestibility of protein in ACSBM and soybean meal was 85.9% and 82.5%, respectively. Results indicated that at least 20% of fishmeal protein can be replaced by ACSBM in diets of juvenile olive flounder without supplementation of limiting amino acids.
Dietary nitrate supplementation from green leafy vegetables and beetroot is involved in the 'nitrate-nitrite-nitric oxide (NO) pathway' and is reported to have important vascular impacts. This study evaluated the blood parameters and blood flow change subsequent to a raw juice diet program. The 28 subjects who voluntarily participated in the raw juice diet program at Sahmyook University were instructed to drink the juice composed of fruits and vegetables instead of partaking the usual meal, at a scheduled time daily. The study was approved by the research ethics council of the Sahmyook University (SYUIRB 2014-043). Evaluation of the participants after the required duration revealed decreased levels of soft lean mass (P<0.05), skeletal muscle mass (P<0.001), body fat mass (P<0.001), body mass index (P<0.001) and circulating levels of total cholesterol (P<0.001), triglycerides (P<0.05), HDL-cholesterol (P<0.01), LDL-cholesterol (P<0.01), and blood urea nitrogen (P<0.001). Conversely, circulating levels of creatinine (P<0.001), hemoglobin (P<0.001), and hematocrit (P<0.01) were increased after the intervention. The blood flow levels were also increased after the program (P<0.001). Our results indicate that a short-term raw juice diet contributes to the improvement of vascular blood flow and blood lipid parameters, and decreases the lean muscle mass related to dehydration.

The effect of silage additives on ensiling characteristics and nutritive value of Napier grass (Pennisetum purpureum) silages was studied. Napier grass silages were made with no additive, fermented juice of epiphytic lactic acid bacteria (FJLB), molasses or cassava meal. The ensiling characteristics were determined by ensiling Napier grass silages in airtight plastic pouches for 2, 4, 7, 14, 21 and 45 d. The effect of Napier grass silages treated with these additives on voluntary feed intake, digestibility, rumen fermentation and microbial rumen fermentation was determined in 4 fistulated cows using $4{\times}4$ Latin square design. The pH value of the treated silages rapidly decreased, and reached to the lowest value within 7 d of the start of fermentation, as compared to the control. Lactic acid content of silages treated with FJLB was stable at 14 d of fermentation and constant until 45 d of ensiling. At 45 d of ensiling, neutral detergent fiber (NDF) and acid detergent fiber (ADF) of silage treated with cassava meal were significantly lower (p<0.05) than the others. In the feeding trial, the intake of silage increased (p<0.05) in the cow fed with the treated silage. Among the treatments, dry matter intake was the lowest in the silage treated with cassava meal. The organic matter, crude protein and NDF digestibility of the silage treated with molasses was higher than the silage without additive and the silage treated with FJLB. The rumen parameters: ruminal pH, ammonia-nitrogen ($NH_3$-N), volatile fatty acid (VFA), blood urea nitrogen (BUN) and bacterial populations were not significantly different among the treatments. In conclusion, these studies confirmed that the applying of molasses improved fermentative quality, feed intake and digestibility of Napier grass.
Effects of feeding of 9.95 mg free gossypol/kg live weight through cottonseed meal (CSM) were studied in 20 intact male calves fed barley or sorghum as source of cereal during the experimental duration of 210 days. Serum concentration of total protein, albumin, globulin and their ratio did not vary because of protein (gossypol) or cereal sources. Serum level of cholesterol and urea were lower (p<0.05) in sorghum than barley fed calves. Feeding of gossypol through CSM enhanced (p<0.05) serum cholesterol. An interaction between protein and period was observed with respect to serum concentrations of urea, creatinine and alanine transferase. The levels of serum creatinine and alanine transferase increased (p<0.05) following 120 days of experimental feeding in calves fed CSM diets compared to the control animals fed groundnut meal diets. No effect of feeding gossypol was, however, evident on the serum enzymes viz. alanine and aspartate transferases and alkaline phosphatase. Moreover, the source of cereal and protein did not appear to influence the metabolic profile of the calves. Humoral immune response, measured through antibody titre against Brucella abortus S99 innoculation, revealed a delayed and depressed seroreactivity indicative of immunocompromisation because of the phytotoxin gossypol. In conclusion, the feeding of gossypol at the designated levels, although had no deleterious clinico-biochemical manifestations, affected the humoral immune response of the calves.

The effect of soybean meal and barley supplementation of the utilization of rice straw was investigated. Balance trials were conducted with three Japanese Corriedale wethers fed rice straw supplemented with soybean meal and barley at three different levels of protein: low (40 g CP/d, LCP), medium (67 g/d, MCP) and high (94 g/d, HCP). In addition, all the supplements were formulated to contain the same amount of TDN (275 g/d). Voluntary intake of rice straw was not affected by any supplementation, while digestibility of organic matter in sheep given HCO diet was significantly higher (p<0.05) than those on LCP diet. Crude protein, neutral detergent fiber (NDF) and acid detergent fiber (ADF) digestibilities of MCP and HCP diets were significantly improved (p<0.05) over the LCP diet. Average daily gain of the animals under MCP and HCP diets were significantly higher (p<0.05) than those under LCP diet. Differences of rumen pH among the treatments were not significant, while concentration of rumen $NH_3-N$ was significantly higher (p<0.05) for HCP diet than for LCP and MCP diets. Total volatile fatty acids ($VFA_s$) and blood urea nitrogen (BUN) concentrations were significantly higher (p<0.05) in sheep fed MCP and HCP diets than those fed LCP diet, while plasma total protein concentration was not affected by any supplementation. Sheep fed MCP diet had a higher nitrogen retention than those fed LCP and HCP diets. It was concluded that rice straw was utilized better by sheep when SBM and barley were supplemented at the medium level of protein.
The present study was conducted to investigate the feasibility of feeding neem kernel meal (NKM) containing diet to growing Japanese quails, which was incorporated into a standard quail diet at 0, 50, 75 or 100 g/kg in place of soyabean meal and deoiled rice bran. Each diet was offered to 30 quail chicks housed in battery cages from day one to five weeks of age. The chicks fed NKM diets gained 123.3, 122.6 and 121.6 g mean body weight, respectively, and which were significantly (p<0.05) lower than that of 129.9 g gained by those of birds fed the control diets. The feed intake and feed conversion ratio of birds in different dietary groups were not significantly altered due to dietary variations. Mean values for retention of dietary energy, N and Ca were found to insignificantly differ (p>0.05) among the treatment groups but P retention was significantly (p<0.01) lower for quails fed 100 g/kg NKM than those in other groups. Blood biochemical constituents, carcass characteristics and organoleptic test for meat also were not found to vary significantly (p>0.05) due to dietary treatments. The histopathology of liver and kidney tissues from NKM fed quails revealed mild degenerative changes. It could be concluded that inclusion of NKM in quail diet reduced the growth besides inducing mild pathological changes in liver and kidney tissues.

This study was conducted to investigate the effect of ingestion of sesame (Sesamum indicum) gruel as a nourishing meal upon the plasma gastrin concentration in normal Korean. Sixteen normal persons with no history of gastrointestinal diseases, including male and female were studied. After an overnight(about 15 hrs) fast, eight persons(mean age: 26.6, range: $20{\sim}40$ years) of them ingested a 350 ml sesame gruel corresponding to 12 g protein, 13 g fat and 99 g carbohydrate, and the remaining 8 subjects(mean age: 21.3, range: $20{\sim}24$ years) ingested a 350 ml glutinous rice gruel(control meal) corresponding to 8 g protein, 1 g fat and 115 g carbohydrate. The venous blood samples were drawn before and after the ingestion of the test meal for the measurement of gastrin by means of radioimmunoassay. 1) Plasma gastrin concentration in response to the ingestion of sesame gruel or glutinous rice gruel increased significantly compared with the concentration in fasting state. 2) Mean increment or percent increment in postprandial plasma gastrin concentration after the ingestion of sesame gruel was not significantly different from that after the control meal, i.e. the glutinous rice gruel. It is inferred from the above results that the ingestion of sesame contained in sesame gruel may have no significant influence on gastrin release in normal human subjects.
A 6-week feeding trial was conducted to determine the nutritional value of various dietary animal protein sources in juvenile Koran rockfish. White fish meal (WFM), flounder muscle meal (FMM), blood meal (BM), casein & gelain (CG), egg white albumin (EWA) and squid liver powder (SLP) were used as the animal protein sources, Crude protein content and available energy of the experimental diets were 50% and 15.9 kJ/g, respectively. There were significant differences among all dietary groups in weight gain (WG), feed efficiency (FE), and protein effiency ratio (PER). WFM and FFM were the best animal protein sources among the dietary groups. FMM diet had significantly higher (P<0.05) WG, FE, and PER values than those of fish fed the WFM diet. WG, FE, PER, and specific growth rate (SGR) values of fish fed BM diet were significantly higher (P<0.05) than those of fish fed EWA diet. Significant differences were found in whole body composition, hemoglobin (Hb), hepatosomatic index (HSI), and hematocrit (Ht). These results showed that low-temperature processing of lyophilized flounder muscle meal resulted in superior performance of rockfish relative to the other evaluated animal protein sources.
This study was conducted to evaluate effects of dietary pine cone meal on growth performance, blood characteristics, carcass quality and fecal noxious gases compounds in finishing pigs. The total of sixty [(Landrace×Yorkshire)×Duroc] pigs(86.01±0.25kg in average initial body weight) were used in 35 days assay. Dietary treatments included 1) T1(2% cottonwood sawdust), 2) T2(1% cottonwood sawdust+1% pine cone meal) and 3) T3(2% pine cone meal). There were three dietary treatments with five replicate pens per treatment and four pigs per pen. During the overall periods, there were no significant differences in ADG(Average daily gain), ADFI(Average daily feed intake) and gain/feed ratio among treatments (P>0.05). Also, Nutrient digestibilities and blood characteristics were not affected by dietary treatments. At the end of this experiment, a*-value of logissimus dorsi muscle color and sensory evaluation color were higher in T3 treatment than T1 treatment(P<0.05). In fatty acid contents of lean, C18:1 and total MUFA were significantly lower in T1 treatment than other treatments(P<0.05). However, total ω6 and total PUFA were higher in T1 treatment than T2 treatment(P<0.05). In fatty acid contents of fats, total SFA was significantly higher in T2 treatment than T3 treatment(P<0.05). C18:1 was higher in T2 treatment than T1 treatment(P<0.05). There were no significant differences in fecal noxious gas compounds among the treatments. In conclusion, the results of the experiment was affected by dietary supplementation of pine cone meal on meat color and fatty acid composition of pork in finishing pigs.

Limiting amino acids (AAs) for milk production in dairy cows fed on a concentrate diet of corn grain and soybean meal was evaluated in this study. Four lactating and multiparous Holstein cows (in third or fourth parities, with an average body weight of 633 ± 49.2 kg), 8 to 9 weeks into their lactation period, were used in a 4 × 4 Latin square design. The experiment comprised four dietary treatments: (1) no intravenous infusion (control); (2) control plus intravenous infusion of an AA mixture of 6 g/d methionine, 19.1 g/d lysine, 13.8 g/d isoleucine, and 15.4 g/d valine (4AA); (3) control plus intravenous infusion of the AA mixture without methionine (no-Met); and (4) control plus intravenous infusion of the AA mixture without lysine (no-Lys). All animals were fed on a controlled diet (1 kg/d alfalfa hay, 10 kg/d silage, 14 kg/d concentrate mixture, ad libitum timothy hay). The AA composition of the diet and blood were determined using an automatic AA analyzer. Milk composition (protein, fat, lactose, urea nitrogen, and somatic cell counts) was determined using a MilkoScan. The results showed that feed intake for milk production did not differ from that of intravenous infusion using a limiting AA mixture. The 4AA treatment numerically had the highest milk yield (32.4 kg/d), although there was no difference when compared with the control (31.2 kg/d), no-Met (31.3 kg/d), and no-Lys (31.7 kg/d) treatments. The concentration of AAs in blood plasma of cows in all treatments, mainly isoleucine and valine, increased significantly compared with that of control. The no-Met treatment increased (p < 0.05) the concentration of lysine in the blood relative to the control and no-Lys treatments, whereas the no-Lys treatment increased (p < 0.05) the concentration of methionine relative to the control and no-Met treatments. In conclusion, milk production increased when feeding 10 g/d methionine to the cows, together with their concentrate diet of corn grain and soybean meal.
