  • Sheep and goats in Pakistan have not been able to produce to the best of their potential. This may primarily be attributed to under feeding and malnutrition. Ranges have been depleted due to overgrazing and mismanagement and are not in position to feed the existing small ruminant population. To overcome the shortage of good quality fodder and balanced feed supply, the alternate means like cereal straws and other crop residues are being commonly used. Sunflower crop residues like stalks and heads provide a good quality forage for livestock. These crop byproducts are rich in crude protein and lower in crude fibre. Their inclusion in the diet of small ruminants at 20, 30 and 40 percent levels in ration has shown significantly (p < 0.05) increased feed intake and weight gain. Daily feed intake was 1,130, 1,180 and 1,750 g for sunflower crop residue, soybean crop residue and wheat straw, respectively, when added at the rate of 20 percent in the ration. The drymatter digestibility of sunflower, soybean crop residues and wheat straw was also comparable. The maximum performance of the animals was observed at the 20 percent level of inclusion of sunflower crop residue in the diet.

  • To evaluate the influence of burrowing substrate on the rearing performance and ambicoloration of cultured flounder, Paralichthys olivaceus, we compared the daily food intake (DFI), feed efficiency (FE), survival, growth, proportion of pigmented skin on the blind side, and proportion of ambicolored fish. We reared juvenile flounders [total length (TL) $4.46{\pm}0.06cm$, body weight (BW) $0.77{\pm}0.03g$] in dark-green fiberglass-reinforced plastic (FRP) aquariums without (control) or with gravel substrate at a density of 200 fishes/ton for 120 days. While there was no difference in survival rate or growth, the DFI was lower and FE higher in the group raised with substrate than in the control. The proportions of pigmented area on the blind side and ambicolored fish were significantly higher in the control tank. Therefore, the supplement of substrate on the aquarium bottom positively affects the feeding efficiency, and inhibits abnormal pigmentation on the blind side in flounder farming at high density.

  • Two experiments were made. In experiment 1, four diets containing 0, 5, 15 and 25% washed seaweed meal were prepared to study the effects of incorporating seaweed meal instead of equivalent amounts of berseem leaf meal in fish feeds on growth performance and feed utilization of common carp. The results showed that average daily gain (ADG), specific growth rate (SGR%), dry matter (DM) and ether extract (EE) of the carcasses were decreased (p<0.05) with the increasing level of seaweed meal in the feeds. Inclusion of 5% seaweed meal in the diet gave the best feed conversion ratio (FCR) among all diets, however, protein productive value (PPV) and energy utilization (EU) were decreased (p<0.05) with increasing level of seaweed meal in the diet. In experiment 2, washed seaweed meal was either steam cooked or sprayed with NaOH (0.5% or 1% NaOH) and incorporated in the diets at the level of 25% instead of equivalent amount of berseem leaf meal. The results showed that steam cooked seaweed gave the best (p<0.05) growth performance, FCR and protein efficiency ratios, PER and PPV, for other treatments in descending order were NaOH treated seaweed, washed seaweed and unwashed seaweed.

  • Yellow mealworms (Tenebrio molitor Linnaeus) are very promising insects for the food and feed industry. Because mealworms are in the spotlight as an alternative protein source in the future, it is necessary to develop efficient rearing techniques for mass production. To evaluate the effects of brewer's yeast (BY) on the growth of mealworms, Tenebrio molitor Linnaeus, the mealworms were fed with wheat bran (WB) diets containing different levels of BY (0, 10, 30, 50, and 70%). Larval survival, larval weight, development time, pupal weight and eclosion rate were monitored for 12 weeks. The results showed that mealworms fed on the diets containing 30% and 50% of BY have significantly higher weight gain, specific growth rate and daily weight gain, and lower larval duration than fed the control diet (100% WB) and other BY diets (10% and 70% BY). Larval survival on the diets containing 30% and 50% of BY was higher than on control diet. Pupal weight and eclosion rate were not significantly different among all diets. In conclusion, we suggest feeding the diet containing 30% of brewer's yeast with wheat bran in order to increase the production of mealworms.

  • To find out suitable indoor rearing tank shape and stocking density of the abalone Haliotis discus hannai, young abalones were reared in the square or ellipse shape tanks with various stocking densities and were fed dried sea mustard, Undaria Pinnatifida HARVEY for three years. There were no significant differences between the square rearing tank and the ellipse one in growth rate and survival rate. With regard to vertical design of rearing tanks with three floors, the significant differences were not found among culture floors. However, the growth and survival rates of young abalones from the running water system were significantly higher than those of the abalones from the circulating system (P< 0.05). For the stocking density experiment with 1,000, 1,500 and 2,000 individuals of 20 mm young abalone, there was no significant differences in growth and survival rates among these groups. However, in that of 200-400 individuals of 40 mm abalone and 100-300 individuals of 50 mm abalone, the lower stocking density of young abalone showed the higher growth and survival rates. The lower stocking density and the smaller size of young abalones showed the higher daily feeding rate and feed efficiency.

  • The pulse diagnosis studies reported to date has mainly been performed to clinically reveal the pulse wave characteristics according to the specific diseases, whereas no attempts have been made to study the effects on the pulse wave characteristics of the daily activities such as taking meals, exercise, and sleep, etc. This work reports the effect of feeding stimulus on the healthy subjects on the pulse wave pattern which has quantitatively been analyzed using the objective model for the pulse diagnosis in oriental medicine. The pulse waves right before/after the meal and 30 minutes after the meal were measured using the pulse analyzing equipment (3D-Mac, Daeyo Medi, Korea) and at the same time oriental medicine doctors' diagnoses were given. The pulse parameters obtained from the equipment and clinical records on the subjects were statistically processed and the variables showing statistically significant differences were analyzed. The results indicate that the pulse pressure, the pulse rate, and the respiratory rate increase while the blood pressure decreases after the meal. For the floating/sinking and the deficient/excess coefficients characterizing the pulse states described in the oriental medicine, the floating/sinking coefficients were observed to decrease whereas the deficiency/excess coefficients increase after the meal. The results indicates that besides the standard bio-indicators like blood pressure and respiratory rate, etc., the pulse wave characterization in terms of the pulse classifications in the oriental medicine using the floating/sinking, deficient/excess pulse states provide an important piece of biomedical information.

  • This study investigated the effects of ozone-produced oxidants (OPO) on the growth, hematology, and histology of olive flounder Paralichthys olivaceus (average weight 500 g), raised in an ozonated semi-recirculating aquaculture system. The system was ozonated to maintained OPO concentrations of 0.004 (Control), 0.014 (OPO15), and 0.025 (OPO25) mg $Cl_2/L$ in culture tanksfor 26 days. The specific growth rate, feed conversion ratio, and survival rate did not significantly differ among the groups (P>0.05), while the daily feeding rate decreased OPO-dose-dependently (P<0.05). OPO appeared to affect the gill, hepatopancreas, and kidney tissues of fish from ozonated tanks. Hematologically, OPO affected some blood indices. The levels of chloride, glucose, glutamic oxaloacetic transaminase, and glutamic pyruvic transaminase were significantly increased in the ozonated groups, while the total cholesterol and cortisol decreased dose-dependently. These results imply that long-term exposure of olive flounder to an OPO concentration ${\geq}0.014mg\;Cl_2/L$ might result in damage to the gill, hepatopancreas, and kidney tissues and cause physiological stress, albeit with no apparent short-term effects on growth or survival.

  • This study was carried out to investigate the effects of the organic feed on weight gain, feed conversion rate, and carcass characteristics of Hanwoo steers. Three feeding treatments(T1 : rice straw and commercial concentrates, T2 : organic hay and concentrates, T3 : organic corn silage and concentrates) for 22 months (from 6 to 28 months) were used. As a result, weight gain was not significantly different among treatments throughout this study. Also T1 tended to improve weight gain and daily weight gain without significance. The percentage of meat quality grade over the first grads ($1,\;1^+,\;1^{++}$) were 50% in the carcass of Hanwoo steers fed T1 and T2, and 70% fed T3, respectively. T2 and T3 tended to improve marbling score and oleic acid content.

  • The in vivo digestibility of mulberry leaves (Morus alba) and the effects of the partial replacement of cotton seed with fresh mulberry leaf in rations on the performance of growing Vietnamese cattle was investigated. For the in vivo digestibility trial, twenty castrated rams of Phanrang breed (a local prolific breed) with an initial weight of 23-25 kg, were first assigned to four groups according to weight and then randomly assigned to one of four dietary treatments to determine digestibility of nutrients in mulberry leaves (M. alba), natural Bermuda grass (Cynodon dactylon), elephant grass (Pennisetum purpureum) and buffalo grass (Panicum maximum cv. TD 58). All forages were cut and chopped daily before being offered (at 120% maintenance) to the sheep. In the feeding trial, 20 Laisind (Vietnam yellow cows${\times}$Red Sindhy bulls) crossbred bulls averaged 18 month old and 184 kg were used to investigate the effect of partial replacement of cottonseed in the diet by mulberry leaves on live weight gain and feed conversion rate. The experiment was a randomized complete block design with four levels of fresh mulberry leaves which varied from 0 to 15% of total dietary dry mater and five animals per treatment over an 84 day period. The in vivo digestion trial showed the superior quality of mulberry leaves compared with the grasses. Chemical analysis indicated that mulberry leaves had the highest CP and the lowest NDF contents (22.3 and 31.1% DM, respectively) among the four forages tested. Digestibility of DM and OM of the mulberry leaf (66.4 and 71.8%, respectively) was also the highest but that of CP (58.2%) and NDF (58.4%) was the lowest of the four forages evaluated (p<0.05). Consequently, the ME value and therefore net energy (NE) and unit feed for lactation (UFL) values of the mulberry leaves, which was estimated from chemical composition and digestibility values, were the highest among the forages investigated in the present study. Results of the feeding trial showed no treatment effect on average daily gain (ADG) of the cattle. The values were 554, 583, 565 and 568 g/d for animals in the diets of 0, 5, 10, and 15% mulberry leaves inclusion, respectively. Total DM intake of the animal was not affected by the treatment when expressed as kg/animal/d. However, when adjusted for metabolic weight of the animal the DM intake was reduced (p<0.05) as whole cottonseed was replaced by mulberry leaves in the ration. When the level of mulberry leaves in the ration increased from 5 to 15% of dietary DM at the expense of whole cottonseed, CP and ME intakes of the cattle were significantly decreased (p<0.05) and the feed to gain ratio reduced by 8 to 14% as compared with the control diet (p<0.05). Mulberry leaf is a good feed ingredient for ruminants because of its high level of crude protein and high digestibility of nutrients and energy. Mulberry leaves can be efficiently used as a source of protein supplement to replace cottonseed, a more expensive animal feeds ingredient, in the diet for Vietnamese cattle.

  • Effects of feeding browses on growth and meat quality of Korean native goats were investigated. Twenty eight heads of male goats were divided into four treatment groups fed diets containing oak browse, pine browse, fermented pine browse, and rice straw. Growth rate, feed intake, carcass and meat quality and blood and serum criteria were investigated. The highest average daily gain of goats was 45.3g from oak browse, and goats on pine browse gained similar to those on fermented pine browse. Daily forage intake was 197g DM for oak browse and 74g DM for fermented pine browse. Feed efficiency(g feed/g gain) of oak browse was 11.0g and that of pine browse was 15.1g. From the results of serological inspection, metabolism in body was normal with all the browses tested. Dressing percentage was 45.1~46.2% and meat percentage was 55.2~55.9% without significant differences between diets. Fat percentage of goat carcasses fed rice straw was higher than those fed pine browse or fermented pine browse which was, however, not significantly different from those on oak browse. Shear force and coking loss of goat meat on pine browse or fermented pine browse was less than those on rice straw(p〈0.05) without significant differences between other browses. Juiciness, tenderness, and flavor of the goat meat were the better(p<0.05) from the pine browse diet than from rice straw.
