Dietary Treatments

Ninety-six male goslings were allocated and assigned to treatment using a completely randomized design. Dietary treatments included a basal diet consisting of corn, wheat, and soybean meal with either no additional selenium (CON), 0.3 mg/kg of inorganic selenium (I-Se; sodium selenite), or 0.3 mg/kg of organic selenium (O-Se; selenium-enriched yeast). After a 56-day feeding period, geese were slaughtered on a common ending day and two geese per pen (n = 24) were used for the analyses conducted in this study. Meat (equal portions of the breast and thigh meat) and liver were collected and evaluated for proximate composition, fatty acid profile, pH, phenolic content, thiobarbituric acid reactive substances (TBARS), and total volatile basic nitrogen (TVB-N) over a 9-day storage period at 4 °C. The meat and liver samples from geese supplemented I-Se or O-Se had greater (p < 0.01) lipid content compared with geese not supplemented with additional selenium. At the conclusion of the 9-day storage period, meat and liver samples from geese supplemented I-Se or O-Se had lower (p < 0.05) pH values, greater (p < 0.05) phenolic content, lower (p < 0.05) TBARS values, and lower (p < 0.05) TVB-N compared with geese not supplemented with additional selenium (CON).

<p>This study was conducted to determine the effects of inorganic selenium (sodium selenite) and organic selenium (selenomethionine) supplementation on growth and viability of juvenile humpback grouper (Cromileptes altivelis). The experiment was designed as a completely randomized design with eight treatments and three replications. The treatment being tested was source and dosages of selenium ie., inorganic selenium (sodium selenite) supplementation with dosages of 0.5, 1, 2, and 4 mg Se/kg diet and organic selenium (selenomethionine) with dosages of 1, 2, and 4 mg Se/kg diet. Another treatment was unsupplemented selenium. Juveniles humpback grouper at an initial average length of 6,39±0,41 cm and body weight of 4,49±0,65 g were reared in 90×40×35 cm3 aquaria and fed artificial diet (pellet) two times daily (08.00 and 16.00) at satiation. Fishes were reared for 40 days at a stocking density of 12 fish per aquarium on sea water with salinity of 30–31 ppt and temperature of 28–29 °C. The results of this study showed that the source of selenium supplementation (inorganic or organic) affected growth performance, glutathione peroxidase (GPx) enzyme activity, and blood profiles of the experimental fish. Generally, it was found that selenomethionine supplementation resulted in better fish performance than sodium selenite. In sodium selenite supplementation, survival declined with the increased dosages of Se in the diet, and the supplementation at dosage of 0,5 mg Se/kg diet showed a toxic effects. Histopatological test showed that there were damage in livers, kidneys, and intestines of fish supplemented with sodium selenite from 0.5 to 4 mg Se/kg diet. On the contrary, supplementation of selenomethionine up to 4 mg Se/kg did not show any signs of toxicity and the survival was on 86.11 to 97.22%. Feed efficiency, protein retention, lipid retention, and Se retention indicated that a dosage of 4 mg Se/kg selenomethionine supplementation was the best dosage.</p><p>Keywords: selenium, viability, growth, Cromileptes altivelis, humpback grouper</p>

The bioavailability of phosphorous, and blood serum and rumen liquor P level was studied in indigenous growing cattle by feeding bone meal and Triple Super Phosphate (TSP) with control diet. Nine indigenous growing cattle (live weight of 164 ± 21 kg) were randomly assigned in a Completely Randomized Design (CRD) to three dietary treatments, consisted of a basal diet (T0) of 0.16% P and experimental diets supplemented with bone meal (T1) and triple super phosphate (T2) to provide P level of 0.44%. All diets were formulated to be iso-nitrogenous and iso-caloric. Three cannulated animals were used for rumen liquor P level study by feeding three diets. Apparent absorption and balance of P were significantly (P<0.01) higher in T1 and T2 diets than that of diet T0, but true absorption did not differ significantly (P>0.05). Bioavailability of P of control diet (37.41%), bone meal (81.45%) and triple super phosphate (80.49%) were significantly differed (P<0.01). Rumen liquor and blood serum P level differed significantly (P<0.01). Supplementation of bone meal and triple super phosphate results in high blood serum P (P>0.05) with no difference between bone meal and triple super phosphate. The results suggested that the bioavailability of P from bone meal and TSP was high and dietary supplementation of P with bone meal and TSP improved P retention and blood serum P level.

ABSTRACT This study aimed to evaluate the quality of minimally-processed cassava treated with antioxidants and a starch-based edible coating. Cassava roots were washed, cooled, immersed in cold water, peeled and then cut. Root pieces were then immersed in a chloride solution, centrifuged, and subsequently immersed in either a starch suspension (3%), a solution containing antioxidants (3% citric acid and 3% ascorbic acid), or in both the coating and antioxidant solutions. Coated root pieces were dried at 18 ± 2°C for 1 hour, then packaged into polypropylene bags (150 g per pack) and kept at 5 ± 2°C for 15 days, and assessed every 3 days. A completely randomized design was used in a 4 × 6 factorial consisting of the treatment (control, coating, antioxidant, or coating and antioxidant) and the storage period (0, 3 6, 9, 12 or 15 days), with three replicates in each group. The pH, blackened area and peroxidase and polyphenol oxidase activities of the cassava was reduced in treatments containing antioxidants and the scores of visual analysis and phenolic content were higher. Therefore, treatment with antioxidants was effective for reducing browning in minimally- processed cassava, retaining the quality of cassava pieces stored for 15 days at 5 ± 2°C. The combination of antioxidants and the edible coating showed no improvement compared to treatment with antioxidants alone.

Abstract Distillers dried grains with solubles (DDGS) has a high concentration of Leu, and the Trp requirement for growing pigs may be increased if diets contain excess Leu. Therefore, the objective of this experiment was to determine the optimum standardized ileal digestible (SID) Trp:Lys ratio in growing pigs fed diets with excess Leu from DDGS. A diet based on corn, soybean-meal, and 35% DDGS was formulated to be deficient in Trp and Lys, according to NRC requirements (0.13% SID Trp; 0.88% SID Lys; 15% SID Trp:Lys ratio). Four diets were prepared by adding L-Trp to the basal diet, which resulted in analyzed SID Trp:Lys ratios of 18, 20, 23, and 24% in these diets. One-hundred and twenty growing pigs (26.3 ± 2.0 kg) were allotted to one of the 5 dietary treatments with 3 pigs per pen and 8 pen replicates in a completely randomized design. Diets were fed for 21d and blood samples were collected on d-21. Data were analyzed by linear and quadratic contrasts in SAS. The optimal SID Trp:Lys ratio was estimated using linear broken-line (LBL) and quadratic broken-line (QBL) regressions for ADG and G:F, using NLIN procedure in SAS. Results indicated that average daily feed intake, ADG, G:F, and final body weight increased (linear and quadratic, P &lt; 0.01) and plasma-urea-nitrogen decreased (linear and quadratic, P &lt; 0.05) as dietary SID Trp:Lys increased (Table 1). The SID Trp:Lys ratio to optimize ADG was 20.9 and 23.4% by LBL and QBL, respectively. The G:F was optimized at 18.7 and 20.2% by LBL and QBL, respectively. The average SID Trp:Lys ratio for the 4 measurements was 20.8% which is greater than the current NRC requirement (SID 17.3%). In conclusion, diets formulated with 35% DDGS may need more dietary Trp than current NRC values.

The objective of the experiment was to evaluate effects of dietary supplementation of β-mannanase (Hemicell®) on productive performance, egg quality, and fecal moisture content in laying hens from 20 to 35 weeks of age. A total of 375 Isa Brown’s hens (1615.6 ± 76.4 g/bird) were randomly assigned to 5 treatments in a completely randomized design. The 5 dietary treatments included (1) basal diet with a level of 2800 kcal ME and no β-mannanase supplementation (HE, Control), (2) HE + 32 units of β-mannanase/g of feed, (3) HE + 64 units of β-mannanase/g of feed, (4) basal diet with a level of 2700 kcal ME (LE) + 32 units of β-mannanase/g of feed, and (5) LE + 64 units of β-mannanase/g of feed. Each treatment was replicated with 25 cages of 3 hens each. All diets were in meal form and contained no antibiotics. The addition of β-mannanase to HE diets did not affect the egg production of birds as compared with the control (P > 0.05). The birds fed LE diets with β-mannanase had the same egg production as those fed the control and β-mannanase-supplemented HE diets (P > 0.05). Differences in egg weight, egg quality, survival rate, and fecal moisture content were not significant among the treatments (P > 0.05). Briefly, addition of β-mannanase (32 units/g of feed) to LE diets would be beneficial for layers during the early laying period as it resulted in the same performance and egg quality as the HE diets without β-mannanase supplementation.

Haematological and serum biochemical parameters are indicators of physiological, nutritional and pathological status of animals. Investigation of these parameters provide information for diagnostic purposes. The study was conducted to determine the influence of feeding graded levels of yam peel meal (YPM) as a replacement for maize on haematology; blood chemistry was evaluated in rabbits. Thirty- six (New Zealand white X Chinchilla) were randomly assigned to four dietary treatments in a completely randomized design with nine rabbits per treatment. The rabbits were fed diets containing 0, 12.5, 25 and 37.5% of Yam peel meal (YPM) as a replacement for maize, designated as T1, T2, T3 and T4, respectively. The experimental diets and clean drinking water were supplied ad libitum throughout the experimental period of nine weeks. At the end of the feeding trial, three rabbits per treatment were randomly selected for hematological and serum biochemical analysis. All the haematological and serum biochemical indices except AST were affected (P<0.05) by dietary inclusion of YPM. Although most of the parameters investigated were affected by rabbits fed test ingredient, the values fell within the normal literature reference values for rabbits. It can therefore be concluded that up to 37.5% inclusion level of YPM can be fed to growing rabbits without deleterious effects on health status.

Background: Choline is a nutrient with numerous metabolic functions, but its requirements for ruminants are unknown. The supplementation with bypass choline could enhance productivity. Methods: Twenty-four male lambs (Rambouillet 23.5 kg±3.17 kg initial BW) were fed a basal diet with treatments which consisted of a control and oral doses of ruminally-protected choline (4 g/d RPC) and plant-based choline (4 g/d Biocholine) in a completely randomized design with initial weight as a covariate. The experiment was conducted for 42 days during which live weight, dry matter intake, carcass characteristics, blood metabolites and basic hemograms were measured. Result: The daily gain in lambs was similar between treatments. Intake was higher in lambs given Biocholine (1.32 kg/d). The L* (represents the light to dark color) value and mineral content in the meat were improved with both sources of choline. Blood triglycerides increased by RPC compared with the other treatments and cholesterol was reduced by Biocholine. Alanine transaminase (ALT) and aspartate aminotransferase (AST) activity decreased by effect of choline. Hematological parameters were affected by choline supplementation regardless of the source; erythrocyte, monocytes and lymphocytes count decreased with both sources of choline in growing lambs.

Two experiments were carried out to determine the bioavailability of phosphorus in two spray-dried yeasts - sugarcane yeast (SCY), and sugarcane yeast + brewer's yeast (SCBY) - in starting pigs, by comparing different methods (Apparent Digestibility Coefficient of Phosphorus - ADCP; True Digestibility Coefficient of Phosphorus - TDCP; slope ratio; and standard curve). In experiment I, a digestibility assay were carried out using 30 cross breed pig with initial weigh of 22.69 ± 4.24kg, allotted in a completely randomized design. The mean ADCP and TDCP values were 62.68 and 64.15% for SCY and 77.01 and 79.33% for SCBY. ADCP and TDCP for SCBY were higher (P<0.05) than the values for SCY. In Experiment II, a growth test was conducted, 56 crossbred piglets, were utilized, with initial live weight of 15.11 ± 3.43kg, allotted in a completely randomized design, with seven treatments, four replications, and two pigs per experimental unit. The treatments consisted of a basal diet without supplementation with P and the same diet including supplementation with two levels of P (0.053% and 0.105%) from dicalcium phosphate, SCY and SCBY. The relative bioavailability mean value of 57.23% for SCY and 91.96% for SCBY, corresponding to 0.30% and 0.40% of available phosphorus, respectively.
