The objective of this study was to conduct field experiments comparing formulated (extruded pellets (E.P)) and raw-fish (moist pellets (M.P)) feeds at two flounder aquaculture farms for six months to obtain the basic data necessary for improving aquafarmers’ awareness of feed-quality issues and firmly establish and expand the use of formulated feed. According to the results, the M.P group was higher in weight gain, feed efficiency ratio, protein efficiency ratio, and specific growth rate and lower in mortality rate than the E.P group. All cases of mortality were caused by six kinds of disease, four of which (Vibrio sp., Edwardsiella sp., Streptococcus sp., and Scuticociliates) were common to the two groups, whereas Lymphocystis arose only in the M.P group and abdominal inflation only in the E.P group at both farms. As for mortality in the present experiment, the numbers were 1047 at Da-Hae farm and 1167 at Global farm, with more fish dying in the E.P tanks than in the M.P tanks. By multiplying the number of deaths by selling price, the economic losses were $9650 and $10,756, respectively. Therefore, it should be considered an urgent priority to develop flounder-exclusive formulated feed for improved digestion and absorption rate and also to establish a water-quality-improvement management plan.

Chronic unpredictable environmental stress (CUES) may induce predisposition to diabetes mellitus. This study investigates the role of CUES on impaired homeostasis. Stressed group mice (n = 20) were exposed to CUES for 16 weeks. Weekly body weight, feed consumption, feed efficiency ratio, fasting blood glucose were monitored. Plasma HbA1c, plasma cortisol, plasma epinephrine and plasma insulin, serum lipids, antioxidants and carbohydrate metabolizing enzymes activity were assessed along with DNA damage and histopathological examination of liver, kidney, pancreas, spleen and skeletal muscles. Fasting blood glucose levels & HbA1c in the stressed were significantly higher compared to control (p < 0.001). Serum lipids were found insignificantly higher in stressed mice compared to control. Body weights of the stressed mice and feed efficiency ratio were found significant (p < 0.001). Plasma corticosterone, plasma epinephrine, HOMA-IR was found to be significantly higher in the stressed group (p < 0.001). Plasma insulin level was found to be significantly lower in the stressed group (p < 0.001). Significant changes were observed in antioxidants level, carbohydrate metabolizing enzymes activity, peripheral tissues and DNA integrity. CUES initiates pathogenesis of diabetes.

The present investigation entitled “Studies on growth performance of Cyprinus carpio var. Communis fed with Bacillus clausii supplemented diets” was carried out at Faculty of Fisheries, Ganderbal over a period of 60 days from April 1st to June Ist, 2019. The fingerlings were fed with dry diets containing three concentrations of probiotic viz., (T1: 1%, T2: 1.5%, T3: 2%) and control group (T0: containing no probiotic). The growth parameters including per cent weight gain, Specific growth rate (SGR), feed conversion ratio (FCR), feed efficiency ratio (FER) and protein efficiency ratio (PER) were measured at the end of the experiment. The results showed that the probiotic incorporated diets had significant impact on growth than control group (P<0.05). The highest values of treatment T2 with 2 per cent probiotic showed the highest percent weight gain (74.62%), specific growth rate (0.40), feed efficiency ratio (0.90), protein efficiency ratio (1.82) were observed in treatments with 2% concentration of probiotic where as, feed conversion ratio(1.09) was lower in groups received probiotic through diets than control.

White Leghorn chicks were fed wheat that was stored under the influence of formalin, and wheat that was recently treated with formalin. Also, samples of each of the formalin-treated wheats were dried and fed to chicks during a four-week test period. Results showed that chicks fed the wheat which was stored under the influence of formalin had a similar rate of growth, feed intake and feed efficiency ratio as those fed the control diet. Dietary wheat recently treated with a high level of formalin resulted in a depression in growth and feed intake as well as poorer feed efficiency ratio. Drying either of the wheat samples after formalin treatment resulted in poor chick performance due to a decrease in feed intake.

Present study was undertaken to evaluate the effect of zinc supplementation on growth performance and nutrient utilization in kids. Twenty four goat kids (4-6 month age) were randomly divided into 4 groups (T1, T2, T3 and T4) having 6 kids each. Kids in the group T1 were fed basal diet which contained 29.02 mg Zn/kg DM from ingredients of ration without any additional Zn supplementation. Kids in the T2, T3 and T4 groups were fed the same basal diet with additive 20, 50 and 100 ppm Zn (as ZnSO4) in their diets, respectively. The study was conducted for 90 days. Digestion trial of 7 days was conducted towards the end of experiment to assess the digestibility of the nutrients. Results indicated significantly higher average body weight gain, crude protein (CP) digestibility and better feed efficiency in kids fed diet supplemented with 50.0 mg Zn/kg DM. From the results it was concluded that the Zn supplementation @ 50.0 mg/kg DM in basal diet significantly improved body weight (BW) gain, CP digestibility and feed efficiency ratio (FER) of kids.
