THE EFFECT OF DIFFERENT QUALITY PELLETED FEEDS ON THE GROWTH OF GREEN CATFISH (Hemibagrus nemurus) IN FLOATING NET CAGE

The study was conducted to evaluate the different protein content of fish feed on the growth performance of green catfish (Hemibagrus nemurus). Two thousand fingerlings averaging 3.92±0.32 g of individual body weight were stocked in each floating net cage (3 m x 3 m x 3 m) in Musi River, South Sumatra. They were fed daily for four months with feed protein content of 27% and 31%. The feed was given in pelleted form at 4%-8% of the total body weight. The result showed that the feed with 31% protein content gave better performance and significant different (P<0.05) than 27% protein feed. The feed content 31% protein was optimum for green catfish fingerlings and gave higher average individual weight gain (80.48 g), specific growth rate (2.67%), fat retention (29.48%) and better feed conversion ratio (2.28). Survival rates were the same for 2 treatments and ranged between 94.17%-95.18%.

An experiment was conducted to evaluate the effect of maize green fodder produced by hydroponics system on the performance of eighteen weaned crossbred calves and Calves were divided into three groups T1, T2 and T3 of six each as uniformly. The calf starter in dietary treatments T1, T2 and T3 contained 24, 20 and 17 per cent of Crude Protein (CP), respectively and 70 per cent Total Digestible Nutrients (TDN). The T2 and T3 treatments were made iso-nitrogenous with T1 by supplementing hydroponics maize fodder. The results obtained in the present study showed significant difference among different treatment groups regarding Dry matter intake (DM), total body weight gain, Average daily gain (ADG) and Feed conversion ratio (FCR) with a higher (P less than 0.05) values observed for calves belonging to T3 than groups T1 and T2. Data on digestibility of nutrients does not reveal any difference (P>0.05) among treatment groups. Cost per kg gain was significantly (P less than 0.05) lower in T3 (Rs.102.14) than groups T2 (Rs. 111.64) and T1 (Rs. 119.82). On conclusion, feeding of hydroponics maize fodder as a partial feed substitute of calf starter on protein basis at seven per cent level improves the DM intake, total body weight gain, ADG and lowers the cost per kg body weight gain.

ABSTRACT This experiment was conducted to assess performance of Bacillus sp. probiotic on catfish juvenile Clarias sp. infected by Aeromonas hydrophila. The probiotic content in the diets were 0% (K+ and K-), 1%, and 2% in duplicates. This experiment used randomized design with four treatments and two replications. Juveniles with average body weight of 3.22±0.15 g/fish were reared in the 1.5×2.8×0.5 m3 pond with density of 800 fish/pond. Fish were reared for 30 days and fed three times a day at rate 8% of total body weight. At day 31, catfish were challenged by A. hydrophila 0.1 mL (106 cfu/mL). Post infection observation was carried out ten days with density 10 fish/aquaria. The result showed that fish fed diet containing 2% probiotic gave the best probiotic performance with survival rate of catfish 83.33% after challenged, spesific growth rate 5.40%, and 0,75 of feed conversion ratio. The results of the blood profile showed significantly better results in the treatment of probiotics compared to the positive control after challenge test A. hydrophila. Probiotic Bacillus sp. has given as much as 2% on feed provides better performance on catfish juvenile.

Background: Proper feed formulation is required for successful fish farming activities. Therefore, it is necessary for fish feed to provide optimal growth so that the cultivation business generates profits. Currently, there is very limited information about the appropriate feed for Caranx ignobilis, causing problems with its development. This study aims to provide feed with different protein levels to C. ignobilis. Methods: We will examine the protein levels’ effects on the daily growth rate (DGR), specific growth rate (SGR), absolute growth rate (AGR), feed conversion ratio (FCR), feed efficiency (FE), and survival rate (SR). This research was conducted for 35 days, from June to October 2017, at the Center Brackiswater Aquaculture Development (BPBAP) Ujung Batee, Ministry of Marine Affairs and Fisheries, Aceh Besar, Indonesia. This study used a completely randomized design method, with five treatment levels (30%, 40%, 50%, 60%, and 70% protein feed) and four replications. Results: The results showed that feeding with different proteins on C. ignobilis had a significant effect on the mean values of DGR, SGR, AGR, FCR, FE, and SR. The 50% protein feed gave the best results for C. ignobilis, with a mean DGR value of 0.267 ± 0.005 g / day, a mean SGR of 1.722 ± 0.030% / day, a mean AGR of 0.081 ± 0.003 cm/day, a mean FCR of 1.290, a mean FE 77.755% and a mean SR was 86.667%. Conclusions: Furthermore, feed treatment with increased protein content between 30%–50% has a positive correlation with the growth of C. ignobilis. However, the ability to grow fish will decrease if the feed protein content is >50%.

This experiment was conducted to study the effects of different levels of full fat canola seed low in glucosinolate and erucic acid on the performance of 336 day old quail (Coturnix coturnix japonica). The experiment was performed in a completely randomize design with three treatment and four replicates for each treatment. The experimental treatment included 5 and 10 % full fat canola seed in diet and fed to quail from 1 to 42 days of age. All of the experimental diets were iso-caloric and iso-nitrogenous. The mean total body weight was not significantly influenced by canola seed inclusion levels. But feed intake and feed conversion ratio were significantly increased by supplementation of 10 % full fat canola seed to the diet. Percentage of liver, proventriculus, gizzard, carcass to body weight was not significantly affected by canola seed inclusion levels. But small intestine rate was significantly increased by supplementation of 10 % full fat canola seed to the diet. As a result, it is possible to say that the full fat canola seed low in glicosinolate and erucic acid content could be used up to 10 % level in quails’ diet.

An experiment on the use of duckweed powder as a fish feed on monoculture of silver carp (Hypophthalmichthys molitrix) was conducted in 6 ponds for a period of 75 days. The area of the each pond was one decimal. The experiment was carried out under two treatments, each with 3 replications. A combination of duckweed powder and rice bran at the ratio of 3:1 was supplied at the rate of 4% of total body weight in the ponds under treatment-I. On the other hand, the ponds under treatment-II were without supplying of feed. Each of the ponds under both treatments were stocked with 45 fingerlings of silver carp (H. molitrix). The average initial length and weight of the fingerlings were 14.60 cm and 33.48 g, respectively. The ponds were fertilized fortnightly with poultry droppings at the rate of 2 kg, urea 60 g and TSP 90 g decimal-1. During the experimental period the ranges of physico-chemical parameters viz. water depth (0.82 to 0.90 m), water temperature (17.80 to 26.7 °C), air temperature (19.11 to 28.29 °C), transparency (28.00 to 34.00 cm), dissolved oxygen (6.70 to 8.20 mg L-1), pH (6.70 to 8.00), total alkalinity (170 to 210 mg L-1), free CO2 (0.0 to 3.50 mg L-1), phosphate-phosphorus (1.2 to 2.9 mg L-1), and nitrate-nitrogen (3.1 to 4.5 mg L-1) were within the productive limit and more or less similar in all the ponds under treatments I and II. There were 25 genera of phytoplankton under four major groups and 10 genera of zooplankton under three major groups in the experimental ponds. Mean survival rates under treatment-I and treatment-II were 97.78% and 95.56%, respectively. The specific growth rates (SGR % per day) of the fish found under treatment-I and treatment-II were 0.98% and 0.49%. The calculated net production of the ponds under treatment-I was 1.87 ton ha-1 yr-1 and that of the ponds under treatment-II, was 0.74 ton ha-1 yr-1. By 't' test, it was found that the net fish production of treatment-I was significantly (p<0.01) higher than that of treatment-II, and cost return relationship was found that the net profit of treatment-I and treatment-II were more or less similar. Finally, it can be concluded that duckweed powder as an ingredient of fish feed had significant impacts on production of silver carp, which do not consume duckweed as fresh and raw condition. Thus, duckweed powder can be used as feed for most fishes. Int. J. Agril. Res. Innov. & Tech. 9 (1): 73-83, June, 2019

Abstract Objectives Iodinated contrast media (ICM) could be more appropriately dosed on patient lean body weight (LBW) than on total body weight (TBW). Methods After Ethics Committee approval, trial registration NCT03384979, patients aged ≥ 18 years scheduled for multiphasic abdominal CT were randomised for ICM dose to LBW group (0.63 gI/kg of LBW) or TBW group (0.44 gI/kg of TBW). Abdominal 64-row CT was performed using 120 kVp, 100–200 mAs, rotation time 0.5 s, pitch 1, Iopamidol (370 mgI/mL), and flow rate 3 mL/s. Levene, Mann–Whitney U, and χ2 tests were used. The primary endpoint was liver contrast enhancement (LCE). Results Of 335 enrolled patients, 17 were screening failures; 44 dropped out after randomisation; 274 patients were analysed (133 LBW group, 141 TBW group). The median age of LBW group (66 years) was slightly lower than that of TBW group (70 years). Although the median ICM-injected volume was comparable between groups, its variability was larger in the former (interquartile range 27 mL versus 21 mL, p = 0.01). The same was for unenhanced liver density (IQR 10 versus 7 HU) (p = 0.02). Median LCE was 40 (35–46) HU in the LBW group and 40 (35–44) HU in the TBW group, without significant difference for median (p = 0.41) and variability (p = 0.23). Suboptimal LCE (< 40 HU) was found in 64/133 (48%) patients in the LBW group and 69/141 (49%) in the TBW group, but no examination needed repeating. Conclusions The calculation of the ICM volume to be administered for abdominal CT based on the LBW does not imply a more consistent LCE.

Rate Of Accumulation

Pregnant rats were subjected to either a folic-acid-deficient regimen that produces multiple congenital skeletal malformations, or a control folic-acid-supplemented regimen. Fetal limbs were extirpated on days 16 and 18 of gestation, pooled from each litter, homogenized, and aliquots set aside for hydroxyproline, protein and DNA determinations. We found that (1) the amount of protein recovered per treated limb was approximately half that of controls on both days, (2) the amount of protein recovered per treated or controlday-18 limb was twice that of a day-16 limb, (3) treated limbs constituted the same percentage of total body weight as in controls on day 16, but a smaller percentage than in controls on day 18, and (4) the concentration of hydroxyproline (μg/mg protein) was significantly less for treated limbs than for controls on day 18 of gestation. We noted also that: (1) lowest hydroxyproline concentrations were found in limbs from treated fetuses with gross limb malformations, (2) intermediate concentrations were found in limbs of treated fetuses not exhibiting gross limb malformations, and (3) highest concentrations were found in control limbs. We suggest that the treatment resulted in (1) a decreased rate of accumulation of protein in limbs prior to day 16, but not from day 16 to day 18, (2) a decreased rate of accumulation of some non-protein component(s) in treated limbs from day 16 to day 18, and (3) an altered collagen metabolism.

Total body weight of 9749 reindeer calves and 4798 adult reindeer were measured from 1984 to 1999 on the Seward Peninsula, western Alaska, USA. Growth rates of male and female calves, and annual growth patterns of adults were determined. Male calves grew faster than female calves. Reproductive females were lighter than non-reproductive females during summer but there was no effect of reproduction on average body weights the following winter. Adult males age 3-5 were heavier during summer than winter. Castrated males weighed the same as uncastrated males in summer, but were significantly heavier in winter, and did not display the large annual fluctuations in weight typical of reproductive males and females. Growth rates were higher and body weights greater in this herd than many other cir-cumpolar reindeer populations. We suggest these kinds of physiological indices should be used to monitor the possible effects of spatial and temporal variation in population density and to evaluate changes in herding practices.

Total Body Weight Loss

Abstract Over 2.5 billion people worldwide are overweight or obese. Multidisciplinary weight management interventions have evolved to address the complexity of weight loss for those with one or more chronic diseases, and the trend of weight regain. The aim of these interventions is to encourage sustainable lifestyle changes, resulting in weight loss and weight maintenance and improvements in comorbidities. While some prospective clinical trials have demonstrated efficacy, results are often not reported by real life practices. The aim of this study was to evaluate the effectiveness of a Sydney based multidisciplinary weight management clinic with endocrinology, dietetics, exercise physiology, psychology, and bariatric surgical domains. All patients who attended the clinic for weight loss purposes between March 2017 and April 2019 were included (n=220). A retrospective chart review was conducted. Patient data on weight, BMI, waist circumference, body composition measurements, and selected blood test results and co-morbidities were analysed. All patient therapy included endocrinological input for co-morbidity identification and management, lifestyle intervention (dietetic and exercise physiology input) with optional adjunct pharmacotherapy or psychological counselling. Of the 220 cohort, 20 of the patients had sleeve gastrectomy. Patient retention in the clinic after the first consultation was 85% (n=186), a high rate within the weight management community. 59% of patients achieved a minimum of 5% total body weight loss, including 18% who achieved greater than 10% total body weight loss. Additionally, 31% of patients lost enough weight to decrease their BMI class by up to 2 or more classes. Of the gastric sleeve cohort average excess body weight loss was 32kg (21-56kg) enhanced by multidisciplinary care in the lead up to surgery. Across the cohort some patients completely reversed co-morbidities; including dyslipidaemia (n=1), hypertension (n=3), NAFLD (n=1), pre-diabetes (n=8) and type 2 diabetes (n=3), OSA (n=1). These results demonstrate that obesity is a chronic condition that can be successfully managed. We have demonstrated significant durable weight loss and improvement in metabolic co-morbidities with holistic coordinated care. Future directions include translating this model of care into standard practice in Australia and other countries where obesity to date not received the same coordinated approach as other chronic conditions.
