A broiler feeding trial was conducted to determine the optimum replacement value of sesame (Sesamum indicum L.) meal for soyabean in maize-soyabean diets. A total of 252 day-old Anak 80 strain broiler-type chicks were used. Three replicate groups of 14 birds each were randomly allotted on six treatment diets containing 0, 10, 15, 20, 30 and 40% of sesame meal in the diets. Feed and water were provided ad libitum. Results showed that broiler birds fed up to 15% level of sesame meal in diets performed significantly (P<0.05) better than those fed on control diets for all the parameters studied. Feed consumption and feed efficiency values were also significantly lower for birds fed 15% sesame meal diets compared to those on control. However, sesame meal al 30 and 40 percent in diets significantly (P<0.05) depressed growth performance of broiler birds. It was found from this study that, up to 15% sesame meal could be used in maize-soyabean broiler diet without adverse effect on growth parameters.

ObjectivesProfitability in the beef industry has narrow margins regulated by revenue from output traits like growth and carcass merit, but profitability is also largely impacted by input expenses like feed costs. Selecting for improvements in feed efficiency during the finishing phase, one of the most feed intensive segments of the industry, can help to mitigate those input costs. This study compared growth performance, feed efficiency, body composition, and carcass characteristics in Angus steers (n = 321) from bulls divergently selected for feed efficiency and marbling.Materials and MethodsAngus sires were selected based on high (10th percentile or better) and low (85th percentile or worse) residual average daily gain (RADG) EPD as well as high (fifth percentile or better) and average (near 50th percentile) marbling (MARB) EPD. These criteria resulted in a 2 × 2 factorial design with four breeding lines: high RADG/high MARB, high RADG/average MARB, low RADG/high MARB, low RADG/average MARB. Data were analyzed using MIXED procedures of SAS with RADG and MARB as main effects. Significance was set at α = 0.05. Generation was also analyzed, where generation one (GEN1) steers were from a selected sire while generation two (GEN2) steers were from a selected sire and a selected dam.ResultsUltrasound and carcass data revealed no differences (P ≥ 0.12) in 12th rib backfat thickness from weaning through slaughter for the RADG EPD groups. Yield grade and dressing percent did not differ (P ≥ 0.56) across RADG or MARB groups. At the beginning and end of the feeding trial, the high RADG (P ≤ 0.02) group had larger ultrasound ribeye area (REA) than the low RADG group. Carcass REA tended (P = 0.08) to be larger in the high versus low RADG steers. During the feedlot trial and through slaughter, body weight was heavier (P ≤ 0.006) for the high versus low RADG steers but did not differ (P ≥ 0.44) across MARB EPD. Feed efficiency measures did not differ (P ≥ 0.32) across RADG or MARB groups apart from the tendency (P = 0.08) for residual feed intake to be lower in the high versus low RADG steers. Marbling scores differed (P ≤ 0.04) across RADG and MARB groups with the low RADG steers and the high MARB steers having improved marbling. The quality grade distribution across MARB EPD revealed that the average MARB steers graded 73% Choice and 25% Prime while the high MARB steers graded 56% and 42%, respectively. Slice shear force did not differ (P ≥ 0.32) across RADG or MARB EPD. Body weights tended (P = 0.06) to be heavier at the start of the feeding trial for GEN1 versus GEN2 steers. Total gain, average daily gain, and feed to gain (F:G) differed by generation (P ≤ 0.007) with increased rates of gain and reduced F:G in the GEN2 versus GEN1 steers. Body weights did not differ (P = 0.72) across GEN at the end of the feeding trial. Backfat thickness at the start and end of the feedlot phase was less (P ≤ 0.03) and marbling score was improved (P = 0.02) in the GEN2 versus GEN1 steers, respectively.ConclusionThese results suggest that selection using RADG EPD has negligible impacts on meat quality; and that progress in selection for efficiency can be achieved while advancing carcass quality and value. Furthermore, continued divergent selection for feed efficiency and marbling has the potential to improve feed efficiency through advancements in the rate of gain, while enhancing carcass merit through marbling.

The present study aimed to investigate the effect of tetramethylpyrazine (TMP) supplementation on growth performance, Campylobacter jejuni (C. jejuni) carriage and antimicrobial peptides in the epithelial tissue of caecum and skin in rabbits. Five treatments included control and C. jejuni challenge with the addition of TMP at 0, 50, 100 or 150 mg/kg of diet. The trial lasted for 35 days and C. jejuni challenge occurred on first day of feeding trial. The results showed that C. jejuni challenge worsened (P &lt; 0.05) feed intake, body weight gain and feed efficiency, whereas TMP supplementation partially compensated (P &lt; 0.05) growth performance. C. jejuni populations in the caecal content and on the skin were decreased (P &lt; 0.05) in the treatments containing TMP. The mRNA levels of antimicrobial peptides, including defensin neutrophil peptide 4, macrophage cationic peptide 2, galectin 3 and cathelicidin were also decreased (P &lt; 0.05) by C. jejuni challenge while they were increased (P &lt; 0.05) with supplemental TMP. Linear and quadratic trends (P ≤ 0.012) of the three doses of TMP were found in growth performance, linear trends (P ≤ 0.049) in C. jejuni carriage, and linear and quadratic trends (P ≤ 0.012) in galectin 3. The results suggest that TMP can partially protect from C. jejuni infection by decreasing C. jejuni carriage and activating epithelial antimicrobial peptides.

The experiment was conducted to compare the growth performance among four genotypes of indigenous chicken namely Non-descriptive Native (ND), genetically Improved Native (IN), Hilly (HC) and Naked Neck (NN) of Bangladesh under free-range rearing system.  A total of 288 day old chicks (DOC) from four genotypes were divided into four treatments having eight replications of each for a period of 12 weeks under free-range system with supplementation of commercial broiler diet. During first 4 weeks, all chicks were kept together, whereas chicks of ND was brooded in the same room but separated by a partition. At 5 weeks of age chicks were randomly distributed to the selected farmers. Growth parameters were recorded to determine the comparative growth performance among four genotypes of chicken. The highest body weight (1110.76 g/bird) was achieved by HC, followed by IN (900.63 g/bird) and NN (831.13 g/bird) at 12 weeks of age. The lowest body weight (734.13 g/bird) however was found in ND chicken. During the growing period under free range rearing (5-12 weeks), HC group consumed the highest amount of feed (2697.02 g/bird) with an average FCR of 3.06 while the lowest feed consumption (2666.13 g/bird) with the highest FCR of 4.90 was observed in ND. IN consumed (2674.63 g/bird) feed with an average FCR of 3.92 and BLRI improved NN consumed (2668.13 g/bird) feed with an average FCR of 4.19. Live weight gains in all the four genotypes of indigenous chicken were changed almost in a similar pattern. Significant differences were observed in live weight, dressing percentage, breast meat, drumstick, thigh meat among the four genotypes of chicken. The HC was superior to other genotypes of indigenous chicken including ND in terms of growth performance, meat yield characteristics and net returns. Bang. J. Anim. Sci. 2018. 47 (2):76-84

Abstract Porcine reproductive and respiratory syndrome (PRRS) virus is one of the most economically significant pig pathogens worldwide. However, the metabolic explanation for reductions in tissue accretion observed in growing pigs remains poorly defined. Additionally, PRRS virus challenge is often accompanied by reduced feed intake, making it difficult to discern which effects are virus vs. feed intake driven. To account for this, a pair-fed model was employed to examine the effects of PRRS challenge and nutrient restriction on skeletal muscle and liver metabolism. Forty-eight pigs were randomly selected (13.1 ± 1.97 kg BW) and allotted to 1 of 3 treatments (n = 16 pigs/treatment): 1) PRRS naïve, ad libitum fed (Ad), 2) PRRS-inoculated, ad libitum fed (PRRS+), and 3) PRRS naïve, pair-fed to the PRRS-inoculated pigs’ daily feed intake (PF). At days postinoculation (dpi) 10 and 17, 8 pigs per treatment were euthanized and tissues collected. Tissues were assayed for markers of proteolysis (LM only), protein synthesis (LM only), oxidative stress (LM only), gluconeogenesis (liver), and glycogen concentrations (LM and liver). Growth performance, feed intake, and feed efficiency were all reduced in both PRRS+ and PF pigs compared with Ad pigs (P < 0.001). Furthermore, growth performance and feed efficiency were additionally reduced in PRRS+ pigs compared with PF pigs (P < 0.05). Activity of most markers of LM proteolysis (μ-calpain, 20S proteasome, and caspase 3/7) was not increased (P > 0.10) in PRRS+ pigs compared with Ad pigs, although activity of m-calpain was increased in PRRS+ pigs compared with Ad pigs (P = 0.025) at dpi 17. Muscle reactive oxygen species production was not increased (P > 0.10) in PRRS+ pigs compared with Ad pigs. However, phosphorylation of protein synthesis markers was decreased in PRRS+ pigs compared with both Ad (P < 0.05) and PF (P < 0.05) pigs. Liver gluconeogenesis was not increased as a result of PRRS; however, liver glycogen was decreased (P < 0.01) in PRRS+ pigs compared with Ad and PF pigs at both time points. Taken together, this work demonstrates the differential impact a viral challenge and nutrient restriction have on metabolism of growing pigs. Although markers of skeletal muscle proteolysis showed limited evidence of increase, markers of skeletal muscle synthesis were reduced during PRRS viral challenge. Furthermore, liver glycogenolysis seems to provide PRRS+ pigs with glucose needed to fuel the immune response during viral challenge.

The aim of this study was to valorize senescent plantain. Therefore, a traditional dish named Dockounou was prepared with a mixture of senescent plantain and various millet, soybean, sorghum, cassava, maize or rice flours. The growth performance of several Wistar rats feed by Dockounou was followed. Thus, batches of rats were fed for 15 days with three formulations (F1, F2, F3) in proportion of 90:10, 80:20 and 75:25 (senescent plantain dough/flours) obtained after two cooking modes (dry cooking: baked ; wet cooking: boiled). The effects of these formulations were compared to control diet (C. diet). Beyond the control diet, rats fed with the soybean baked Dockounou presented, the best following growth parameters: weight gain (2.82 to 4.19 g/d), food intake (8.92 to 9.72 g/d), feed efficiency (0.10 to 0.42), proteins intake (8.28 to 19.67), proteins efficiency (0.13 to 3.15). The physicochemical and nutritive characteristics of soybean baked Dockounou were as follow: ash (2.93 ±0.15 %), proteins (10.62±0.59 %), carbohydrates (15.46±1.53 %), calcium (232.04 – 558.20 mg/100g), potassium (313.97 – 385.11 mg/100g), magnesium (42.40 – 72.22 mg/100g), sodium (211.24 – 303.85 mg/100g) and phosphorus (330.70 – 433.71 mg/100g). Also, the study showed that, two formulations, 80:20 and 75:25, have really impact on rats growth. These results suggest that soybean baked Dockounou with important proportions, 80 % and 75 %, of senescent plantain dough can be effectively used in the diet of laboratory Wistar rats regarding the good zoological performances there are obtained.

Clown loach Chromobotia macracanthus is one of Indonesian native species and as a key species for ornamental aquaculture. The problem in mass production of this species are the low of growth rate which causes a long period of rearing and low of survival rate. The purpose of the present study was to evaluate free glutamine supplementation at different doses in diet to increase physiological response, growth performance and survival rate of clown loach. Expe-rimental diets contained four different free glutamine levels, viz 0, 1, 2 and 3%. These diets were given to six repli-cate groups of 50 juvenile clown loaches. The fish were reared in each aquarium with dimensions of 40×30×30 cm3 for 60 days. Fish were fed four times a day at satiation. Parameters observed including intestinal glutamine concen-tration, villous and intestinal morphometry, intestinal protease activity, feed efficiency, nutrient retention, growth performance, survival rate, superoxide dismutase (SOD) activity, and malondialdehyde (MDA). The results showed that supplementation of 1% free glutamine significantly affected the morphometry of villi. The length and surface area of villi at a dose of 1% showed the highest values i.e., 320.44 ± 10.39 μm and 27,046.79 ± 250.54 μm2, respect-ively. The 1% dose also had a significant effect on protease activity (13.57 ± 1.92 mg units of protein-1) compared to the 0% dose. The 2% dose showed the highest SOD activity (0.82 ± 0.07 mg protein-1 unit) and the lowest MDA level was found at a dose of 3% (0.25 ± 0.02 nmol mg protein-1). Feed consumption with the supplementation of free glutamine has a significant effect on survival rate with the highest value reached 97.00 ± 1.00%, but no significant effect on intestinal morphometry, feed efficiency, nutrient retention and growth performance. Dietary with the sup-plementation of free glutamine is not able to improve growth performance, but can improve the physiological res-ponse and survival rate.

Potato steam peel (SP) is a by-product of potato processing where the peel is removed after steaming. It typically contains 15 ± 3% dry matter, 16 ± 1% crude protein, 0.55 ±.05% lysine, 0% methionine/cystine and 6% ash (dry matter basis). Steaming effectively deactivates the proteolytic enzyme inhibitors and partially denatures the starch. SP was evaluated in a digestibility trial and at levels from 0 to 30% DM in two feeding trials. The digestibility (%) of SP by pigs was found to be 88.4 (DM), 80.1 (CP) and 86.1 (DE). In the first feeding trial diets containing levels of 0, 10, 15, 20, 25 and 30% SP supplemented with methionine resulted in similar growth performance and carcass characteristics. In the second feeding trial, a comparison was made between a constant level of inclusion and an increase in inclusion level with age. Results showed no difference in growth performance or feed consumption among treatments. It is concluded that SP can be incorporated in diets for growing-finishing pigs at levels up to 30% DM. No change in performance resulted from increasing level of inclusion with age. Key words: Potato, steam peel, pigs, digestibility

Growth performance of potted `Peterstar Pink', `Top White', `Red Sails', and `Red Success' were evaluated in eight substrates and three fertilization rates. The substrates included Sunshine Mix 1 and Pro Gro 300S as control, and compost blends at 33%, 50%, and 67% of final substrate volumes mixed with peat and perlite (1:1). The blends included 2:1, 1:1, or 1:2 ratio of polymer dewatered biosolids (PDB):poultry litter (PL) and PDB: yard wastes (YW). Fertilization was applied twice weekly at 75, 100, and 150 mg/L N from 19N--2.2P-16.6K. Plants grown in Sunshine Mix 1 performed better than those grown in Pro Gro 300S. The growth parameters measured improved as the N rates increased for both controls. Plant diameter, grade, and dry weight of plants grown in 150 mg/L N treatment were usually similar to those in 100 mg/L N and were not 11% more than those at the lowest N treatment. The 1 PDB: 1 PL blend at the high N treatment produced premium-quality plants, and all remaining PDB:PL treatments produced good quality plants. The PDB:YW blends that received 100 and 150 mg/L N produced premium quality plants. The PDB:YW blends at the low N treatment produced slightly better quality plants than those grown in PDB:PL at the 75 mg/L N and were similar in quality as those grown in Sunshine Mix 1 at the 150 mg/L N treatment.
