Abstract Coral trout is one of marine fishery commodities with high economic value. This grouper fish has limited ability in the utilization of artificial feed. The aim of this study was to obtain information on the effectiveness of probiotics and prebiotics inclusions in diet to increase growth of coral trout. Fish was reared in fiber tanks 300-L with a density of 30 fish/tank. Fish weight and length were 3.7±0.1 g and 6.3±0.1 cm, respectively. Each tank was equipped with a flowing water system and aeration as a source of oxygen supply. The feed was formulated with 48% protein and 9% lipid. Treatments were inclusion of probiotics in diet (diet A), inclusion of mannan oligosaccharide/MOS (diet B), inclusion of probiotic + mannan oligosaccharide/MOS (diet C), and diet D as control. The study was conducted in a complete randomized design (CRD) with 4 treatments and 4 replications. Fish fed trial diets with a frequency of 3 times a day at satiation. The parameters observed were growth, feed efficiency, feed digestibility, bacteria density and immunity. The data obtained were analysed with anova followed by LSD. The results showed that diet with the probiotic content promoted better growth and feed efficiency of coral trout compared to the other treatments. The highest growth of coral trout fingerlings was obtained by fish fed diet A (added with probiotics) with a weight gain of 794.86%. While fish fed diet containing probiotics and prebiotic (diet C) showed a lower growth response (weight gain 641.26%) than those fed diet with probiotics and prebiotics (MOS) separately. Survival during the study for all treatments ranged from 90.00% to 93.33%.

Abstract Fish hydrolysate contains hydrolyzed protein which comprised of peptides and free amino acids that are easily digested and absorbed by fish. This study aimed to determine the effectiveness of fish hydrolysate in improving feed efficiency and growth of coral trout. Five experimental diets were formulated to contain 47% protein and 12% lipid with different sources and levels of fish hydrolysate. Diet-1 and diet-2 were added with crustacean hydrolysate at 2% and 4% levels, respectively. Whereas diet-3 and diet-4 were supplemented with 2% and 4% of tuna hydrolysate. Diet-5 was formulated without fish hydrolysate supplementation (control). The diets were prepared as dry pellet with 3 mm diameter. Coral trout juveniles were produced in the hatchery of Institute for Mariculture Research and Fisheries Extension (IMRAFE), Gondol-Bali with the average body weight of 7.6 ± 0.9 g. The juveniles were maintained in 15 fiber tanks, 400L in volume, with a density of 40 fish/tank. The experiment was designed with a completely randomized design (CRD) with 5 treatments (different diets) and 3 replications for each treatment. The fish were fed the experimantal diets three times every day at satiation level for 84 days of feeding experiment. Results of the experiment showed that increased supplementation of fish hydrolysate from 2% to 4% in diet tended to improve fish growth performance. However, the best growth performance, in term of weight gain (WG) and specific growth rate (SGR), was obtained in fish fed diet supplemented with 4% crustacean hydrolysate. This growth performance was significantly higher than of the other treatments (P<0.05). The best feed efficiency (FE) and protein efficiency ratio (PER) were also obtained in fish fed diet supplemented with 4% crustacean hydrolysate. The results of the present study showed that supplementation of 4% crustacean hydrolysate in diet effectively improved the growth and feed efficiency of coral trout.

This research aimed to analyze polymorphism of the growth hormone (GH) gene and its implication on digestibility of low and high quality feed. Forty bulls Ongole Grade (OG) and 30 bulls Fries Holland Grade (FHG) had been selected and subjected for an experiment to measure body weight gain, dry matter intake, feed efficiency and feed digestibility. The treatment was crude fibrous feed from various plants with a fibre weight of 15% (P1: low quality) and 22.5% (P2: high quality). The 389 bp of GH gene was amplified (F = 5'-CCCACGGGAGAGAATGAGGC–3'; dan R = 5'-TGAGGAACTGCAGGGGGPA-3') and digested using Msp1 restriction enzyme. Polymorphism between OC and HFC bulls was 45%. The FHG bulls' weight gain were significantly higher than of OC (P<0.05) at first to third week, but become similar (P>0.05) at fourth week. It was concluded that the polymorphism between FHG and OC was high and HFC have a growth response and feed efficiency higher than those of OC.

An experiment was conducted with 3840 male Ross × Arbor Acres broiler chicks to test the effects of increasing dietary methionine and lysine on performance and breast meat yield. Supplemental methionine and lysine were fed in a 2 × 4 factorial arrangement in both starter (0–3 wk) and finisher (3–6 wk) diets. Methionine was fed at levels of NRC and 112% NRC. Lysine was fed at levels of NRC and 106% NRC, 112% NRC and 118% NRC. Increasing dietary methionine increased weight gain (P < 0.01), feed efficiency (P < 0.01) from 3 to 6 wk, and breast meat yield (P < 0.01) at 6 wk. Increasing dietary lysine caused a curvilinear response in breast meat yield (P < 0.05). Key words: Broiler, lysine, methionine, breast meat

SUMMARYIndonesian Ongole and swamp buffalo bulls that had previously been given 0, 1·2, 2·4, 3·6 or 4·8 kg/head/day rice bran plus ad libitum elephant grass were slaughtered after 161 days feeding. Abdominal depot fat, full and empty reticulo-rumen and cold carcass weights were recorded. Various carcass variables were measured and the 9–10–11 rib joints were dissected into bone, muscle and fat. Carcass gross energy was calculated from rib-fat content using previously determined regression equations. Feed efficiency was expressed in terms of the ratios of live-weight gain or carcass-energy accretion to metabolizable energy available for growth.Increasing supplementation with rice bran resulted in larger abdominal fat depots, higher dressing percentages, increased carcass fatness (and hence carcass gross energy) and improved rib muscle to bone ratios. Carcass conformation was unaffected by dietary treatment. When feed efficiency was expressed per unit live-weight gain, there was a decrease with increasing rice-bran feeding. Feed efficiency, expressed per unit of carcass energy accretion, improved with rice-bran supplementation and was generally higher in buffalo than in Ongole bulls. Dietary and species differences in feed efficiency could be primarily explained by the differential energy cost of deposition of, and the availability of energy from, carcass protein and lipid.

Abstract The aim of the study was to evaluate prediction methods, validation approaches and pseudo-phenotypes for the prediction of the genomic breeding values of feed efficiency related traits in Nellore cattle. It used the phenotypic and genotypic information of 4,329 and 3,594 animals, respectively, which were tested for residual feed intake (RFI), dry matter intake (DMI), feed efficiency (FE), feed conversion ratio (FCR), residual body weight gain (RG), and residual intake and body weight gain (RIG). Six prediction methods were used: ssGBLUP, BayesA, BayesB, BayesCπ, BLASSO, and BayesR. Three validation approaches were used: 1) random: where the data was randomly divided into ten subsets and the validation was done in each subset at a time; 2) age: the division into the training (2010 to 2016) and validation population (2017) were based on the year of birth; 3) genetic breeding value (EBV) accuracy: the data was split in the training population being animals with accuracy above 0.45; and validation population those below 0.45. We checked the accuracy and bias of genomic value (GEBV). The results showed that the GEBV accuracy was the highest when the prediction is obtained with ssGBLUP (0.05 to 0.31) (Figure 1). The low heritability obtained, mainly for FE (0.07 ± 0.03) and FCR (0.09 ± 0.03), limited the GEBVs accuracy, which ranged from low to moderate. The regression coefficient estimates were close to 1, and similar between the prediction methods, validation approaches, and pseudo-phenotypes. The cross-validation presented the most accurate predictions ranging from 0.07 to 0.037. The prediction accuracy was higher for phenotype adjusted for fixed effects than for EBV and EBV deregressed (30.0 and 34.3%, respectively). Genomic prediction can provide a reliable estimate of genomic breeding values for RFI, DMI, RG and RGI, as to even say that those traits may have higher genetic gain than FE and FCR.

The Relationship

Data from Danish Progeny Testing Stations were used to investigate the relationship between the colour of meat and feed efficiency in pigs. For groups slaughtered during the summer there was a highly significant correlation. As the amount of feed consumed per unit live-weight gain declined so the meat became paler. For groups slaughtered in winter and for data pooled over the whole year, there was no significant correlation. Possible explanations of these findings are discussed.

This study compared the effects of unchopped and chopped hay on milk production and composition, feed digestibility, and physiology of Lacaune sheep. Eighteen ewes were stratified by parity (two or three), days of lactation (60 ± 3.7 days), and milk production (1.04 L/ewe/day), and were randomly assigned to 1 of 2 treatments: 1) Unchopped or 2) Chopped Tifton 85 hay. Corn silage and concentrate were also provided. Chopped hay ewes gave lower (P≤0.01) dry matter intake and greater (P=0.02) crude protein digestibility. No effects of treatment were detected (P≥0.38) for the digestibility of dry matter, or of neutral and acid detergent fibers. Chopped hay ewes had greater (P≤0.01) milk production (d 7 and d 12), lactation persistence, and feed efficiency. Ewes eating chopped hay had greater (P=0.03) protein concentration in their milk. However, there were no effects of treatment × day and treatments (P≥0.16) for concentrations of fat, lactose, minerals, deffated dry extract, or density. Ewes eating chopped hay presented lower (P<0.01) serum concentrations of urea and tended to have lower (P=0.10) serum concentrations of glucose only on d 12. However, there were no effects of treatment × day and treatments (P≥0.16) for serum concentrations of total protein, albumin, globulin, triglycerides, or cholesterol. These data suggest that chopped hay promotes lower dry matter intake and serum concentrations of glucose and urea, but improves milk production, lactation persistence, feed efficiency, and protein concentration.
