Brood Fish

An experiment was conducted to observe growth performance and survival of the larvae produced from the brood fish of Ompok pabda treated with 4 dietary levels of vitamin E for 90 days viz. 0 (served as control), 50, 100 and 150mg vitamin E/kg feed under 4 treatments i.e. treatment T1, T2, T3 and T4. After the feeding trials, the brood fish were induced to breed with equal dose of PG extract i.e. 12 and 18mg/kg body weight for male and female respectively and subsequently larvae were produced. The experiment was started with 5 days-old larvae having an average weight and length of 21.4 ± 8.6 mg and 13.8 ± 2.49 mm respectively in 16 bowls of 10l capacity divided into 4 treatments corresponding to the broods fish having 3 replications each with 100 larvae in each bowl i.e. 10 larvae per liter. After rearing for 28 days with live-food tubificid worms the highest growth rate in terms of weight (609.13 ± 15.20 mg) and length (86.70 ± 1.84 mm), gain in weight (587.78 ± 15.27 mg) and length (72.98 ± 1.81 mm), specific growth rate (30.36 ± 0.12%), health condition (16.63 ± 0.69 mg/mm) and survival (83.25 ± 2.87) were showed by the larvae produced from brood fish fed with 100 mg vitamin E/kg feed (treatment T3) while poorest was observed by the larvae produced from brood fish fed 150 mg vitamin E/kg feed. The results imply that inclusion of 100mg vitamin E/kg feed in the diet of O. pabda brood fish is best for enhancing growth and survival of larvae indicating that vitamin E has a positive impact. The results also suggest that inclusion of higher level of vitamin E in the diet exerts an antagonistic effect on the produced larvae.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16864 Progress.

An experiment to observe the growth performance of the larvae produced from female Clarias batrachus treated with 4 dietary levels of vitamin E viz. 0 mg, 50 mg, 100 mg, and 200 mg /kg feed was conducted for 28 days. After rearing for 3 months females were used for induction of breeding to produce larvae. Same dose of pituitary gland (100 mg PG/kg body weight) was used for all treatments. From the 7th day of hatching, the larvae were reared for another period of 28 days to see growth and survival rate of the larvae produced by the broods maintained under different dietary levels of vitamin E. In case of growth performance (percent length gain, percent weight gain, specific growth rate) and health condition larvae of T2 (50 mg vitamin E/kg feed) showed significantly better result when compared with those of T1 and T3. There was no significant difference in the growth performance between the larvae of T2 and T4. Larvae of T2 although showed higher survival rate but the difference between different treatments was insignificant. The results concluded that 50 mg vitamin E/kg feed is more suitable to increase growth and survival rate of the larvae.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16862 Progress.

SUMMARYFifty-four pigs weaned at 3 weeks of age were allocated at an average weight of 5·4 kg to two experiments to examine the effects of diets having digestible energy (DE) concentrations ranging from 2910 to 3940 kcal/kg.In the first experiment pig growth performance and the dry-matter digestibility of the experimental diets were measured between 3 and 8 weeks of age. The composition of the carcass at 8 weeks of age was correlated with the composition of various carcass joints.In the second experiment pig growth performance was measured over the live-weight range 5-4 to 20 kg.The findings were:1. Growth rate was linearly related to DE intake.2. The optimum DE level for maximum growth was 3640 kcal/kg.3. The efficiency of utilization of DE for growth did not vary in the first experiment but was poorest at a DE concentration of 3245 kcal/kg in the second.4. The DE content of the diet had no significant effect on carcass characteristics at 8 weeks of age in the first experiment or at 20 kg live weight in the second.5. The proportion of fat and lean in the 8-week carcass was significantly (P < 0·01) correlated with that of the shoulder joint.

The study was conducted to compare the effect of three different fry rearing systems such as: hapa, cistern and pond on the growth and survival of goldfish (Carassius auratus ) fry. A total of 645 fry (mean initial weight: 0.0071 mg) were randomly distributed in the three treatments (systems) each having three replications. The stocking density was same in all the treatments with respect to the water volume of the systems which was 10 fry/hapa, 125 fry/cistern and 80 fry/pond. The trial lasted for 40 days. The water quality parameters were favorable in all the treatments during the period of the study. The growth and survival of goldfish fry varied among the systems. Highest average weight gain and specific growth rate (SGR) were observed in pond followed by hapa and cistern. On the other hand, survival rate was highest in cistern followed by hapa and pond. It can be concluded from the study that the pond was the best system in terms of growth rate and cistern was the best system for survival of gold fish fry.Res. Agric., Livest.

Saline Land

Salinity is a worldwide, threatening problem affecting socioeconomic status globally. Saline land comprises salt content in soil, plants, and drinking water. Livestock farming is the worthy option for proper utilization of saline land in a cost-effective approach. Animals reared on this land experience a variety of stresses. Such stresses promote oxidative stress and reduced animal performance. The purpose of this study was to investigate the antioxidative function of vitamin E and selenium (Se) on pregnant/nonpregnant animals reared on the saline environment. A total of 36 multiparous pregnant ( n = 18 ) and nonpregnant ( n = 18 ) goats weighing about 38-45 (average 41.5) kg were equally divided into control and supplemented groups. The experiment lasted from 120 days of gestation to 15 days after parturition for pregnant goats and 0 to 45 days for nonpregnant cyclic goats (>50 days post-kidding). The supplemented group was administered vitamin E (1000 mg/kg BW) and selenium (3 mg/50 kg BW), while the control group was kept on normal saline (0.9% NaCl) with the same route 15 days apart. The blood samples were collected with 15 days apart during the entire experimental period of 45 days and subjected to assessment of enzymatic/nonenzymatic antioxidants, hydrolytic enzymes, oxidants, stress metabolic biomarkers, Se, and progesterone concentration of (pregnant) animals. Results revealed that vitamin E and Se supplementation significantly enhanced the activity of enzymatic (catalase and peroxidase) and nonenzymatic antioxidants such as total phenolic/flavonoid content and vitamin C and increased blood plasma level of Se concentration in comparison with the control group ( P < 0.01 ). Exposure to antioxidant supplementation mitigated lipid peroxidation and enhanced progesterone level and total antioxidant capacity ( P < 0.01 ) as compared to the control group in pregnant goats. Administration of vitamin E and selenium promoted kid survival rate (100%) along with increased initial birth weight, daily average weight gain, and total weight gain in comparison with the control group. Besides, the twinning rate and sex ratio were also recorded in pregnant animals. It is concluded that vitamin E and Se supplementation ameliorated salinity-induced oxidative stress, improved antioxidant status, and enhanced reproductive and growth performance of suckling kids reared on saline land.

An experiment was conducted at Corona of Agriculture (COA)”, Gunjanagar-3, Chitwan, Nepal to complete a project granted by University Grant Commission (UGC), Second Higher Education Project (SHEP) in 2013. Four (average 380 m2) ponds (W, X, Y and Z) with four different diets as D1 (20%), D2 (30%), D3 (40%) and D4 (50%) protein contents were used to conduct the experiment properly to determine the varied proportion of dietary protein on the growth performance of major carp rohu Labeo Rohita (H) in relation with RNA: DNA ratio. After 12th weeks of culture, average length, average weight and specific growth rate of fish were found significantly (P<0.05) higher in the carp with D3 and D4 diet fed fish. Similar results were observed in average total protein, albumin and globulin contents. RNA content increased rapidly with age. The average RNA content increased highest in D2 and D3 diet fed fish while, DNA content were highest in D3 diet fed fish.  RNA: DNA ratio was recorded highest in D2 and D3 diet fed fish. RNA: DNA ratio, an indicator of protein synthesis and have been used to accurately estimate the growth rate and feeding condition of fish hence, as the dose of protein increased RNA and DNA contents also increased with age of carp cultured during experiment. Thus, it was clear from this study that the incorporation of protein in diet enhances the growth of fish regardless of species weight groups and the doses, as the average weight of fish was significantly lower in control diet fed fish as compared to the treated one.

The study of probiotic application as an important rearing strategy was started more than 30 years ago and most of these studies were carried out to increase growth and survival of larvae. Effect of Bifidobacterium animalis PTTC-1631 and B. lactis PTTC-1736 as probiotic supplement has been studied on growth performance and hematological changes on rainbow trout, Oncorhynchus mykiss alevins with initial body weight of 0.583 ± 0.197 g. The commercial diet was supplemented with graded levels of probiotics (1×107, 2×107 and 3×107 CFU g-1 dry feed) to obtain 3 sets of experimental diets (T1, T2, andT3 respectively) and fed four times a day for 60 days. T1 alevin showed the best growth performance in terms of specific growth rate, weight gain, metabolic growth rate, feed conversion ratio and survival rate. The highest red and white blood cell concentrations were noticed in fish fed T2 and T3 diets, respectively, no significant difference was observed in hemoglobin content. T1 showed the significant elevation of serum biochemical parameters and reduction of cortisol level. The results of present study might suggest likely positive effects of probiotic supplements with concentration of 1×107 CFU g-1 dry feed on growth and hematology on rainbow trout alevins.

A six month feeding experiment was conducted to compare between different diets and its effect on growth performance of an indigenous carp Bangana dero. A total of 360 uniform B. dero (average weight 4.9±0.02 g) were cultured in twelve circular fibreglass tanks @ 15 fish per tank (90 W X 64 H cm.). The fishes were fed by two commercial feeds (T1, T2), formulate feed (T3) and control feed (T4) in triplicates with 4% of body weight twice a day. Fish were maintained in well aerated water system. Analysis of variance showed that the growth performance in T1 was significantly higher than other groups (p 0.05). The formulate diet also had uniform growth rate with significant positive effects on Specific Growth Rate (SGR) and final biomass gain. The present study reveals that there is potential effect of commercial and formulated fish feed on growth performances of this target species.

Catfish is a species of freshwater fish that contains a source of protein and it has economic value and has become one of the famous commodities in Indonesia. Biofloc can be one alternative waste fixers intensive cultivation for reduce the waste of inorganic nitrogen and also provide additional protein for increase growth and feed efficiency. This study was to determine the effect of high stocking densities on the growth performance of african catfish in biofloc system. This study used completely randomized design (CRD) with different stocking densities in the system biofloc T1.(1000/m3), T2.(1500/m3), T3.(2000/m3), and T4.(2500/m3). Animal trials were using jouvenile african catfish with an average weight of 1.06±0.3g, which maintained in a pool tarpoulin cage with water volume ±2000L for 50 days with feeding ratio 3% of the weight biomass. The results showed a significantly different effect (P<0.05) against the value of hepatosomatic index, absolute growth and daily growth rate, but the result not significant at spesific growth rate. The second treatment (T2) showed the best results than others in the growth rate and daily growth rate with a value of 6.45±3.1g for absolute growth and 0.13±0.06g for daily growth rate. The four treatment showed the best results than others in the hepatosomatic index with value 4.7 ± 1.8%. These findings demonstrate a role of biofloc technology in catfish aquaculture.
