Effects of Phase Feeding During Gestation on Gilt Performance, Offspring Quality and Robustness
… in 6 blocks were randomly assigned to one of 3 feeding regimens: Constant (Constant-f), 2.21 kg/d of a standard diet from breeding to d 112 of gestation (1.7 g Lys/kcal ME; 3276 kcal ME/kg); Bump feeding (Bump-f), the standard diet at 2.21 kg/d from breeding to d 89 and 2.61 kg/d from d 90 - …

Periodic reverse flow in microchannel evaporators
… of the microchannel are recorded under both two phase feeding and liquid only feeding modes. In the two-phase feeding mode, churn, bubbly/slug, and annular flows occur alternatively, but the period of each flow regime is not constant. Flow reversal is only witnessed occasionally in the …

Effect of lysine level in the nursery period and number of dietary phases in the growing-finishing period on growth performance and carcass characteristics of pigs
… nursery growth performance resulting from feeding lysine-deficient diets during the nursery period on subsequent performance in the growing-finishing and wean-to-finish periods was evaluated. Finally, the effect of reducing the number of dietary phases fed during the growing-finishing …

The Interactive Effects of Phosporus and Calcium on Phosphorus Requirement, Utilization, and Phytase Efficacy in Poultry
… and bone characteristics in subsequent growth phases. Feeding below the nPP requirement for 0 to 14 d resulted in better adaptation to a lower nPP in the grower phase. Feeding above the nPP requirement for 0 to 21 d resulted in a decrease in ADG at 35 d and G:F at 49 d. One experiment was …

Performance of broiler chickens fed Pearl Millet as an energy source and Acacia Karroo leaf meal as an additive.
… Namib Poultry Industries and raised on a two phase feeding regime (i.e. starter for 3 weeks and finisher for 4 weeks). During the finisher phase they were fed different treatment diets. In the first trial the treatment diets were formulated such that maize was replaced with pearl millet at …

Design and modelling of beam steering antenna array for mobile and wireless applications using optimisation algorithms. Simulation and measrement of switch and phase shifter for beam steering antenna array by applying reactive loading and time modulated switching techniques, optimised using genetic algorithms and particle swarm methods.
… its viability. Then two hybrid coupled PIN diode phase shifters, using Branchline and Rat-Race ring coupler structures, were designed and tested. The generation of four distinct phase shifts was implemented and studied. The variations of the scattering parameters were found to be realistic, with …

Effects of Nutritional Manipulation on Poultry under Normal and Stressful Conditions
… acid requirements of broiler chicks under a phase feeding scenario using different models. Digestible tryptophan requirements were estimated to be 137 for egg production, 133 for egg mass, and 133 for feed efficiency using the linear broken-line model. The lysine and sulfur amino acid …

Coated butyric acid and C12 monoglyceride supplementation of broiler feed to improve performance and gut health
… treatment combinations were implemented in a 3-phase feeding programme: Starter (0 to 14 d), Grower (14 to 28 d) and Finisher (28 to 35 d). This study was conducted using eight different dietary treatments. Treatment 1 was the positive control (Zinc Bacitracin 15% at 0.5 g/kg) and treatment 2 …

Reducing crude protein levels in diets fed to young pigs to optimize growth performance and intestinal health
… not provide AA to meet the requirement. A two-phase feeding program was used in both experiments. In the first experiment, thirty-six weaned pigs (7.87 ± 0.42 kg) were randomly allotted to the 3 dietary treatments with 12 replicate pigs per treatment to test the hypothesis that a reduction in …

Characterizing the amount and variability of intramuscular fat deposition of pork loins using barrows and gilts from two sire lines
… Research Council requirements of swine, for a 3-phase feeding program. All pigs were ultrasonically scanned at wk 10, 15, 20, and 24 of age to estimate marbling, back fat, and loin depth. Two or four contemporary pigs were scanned at each of these time points and then slaughtered on the following …

Isoquinoline alkaloids in diets for young growing pigs improve nutrient digestibility and gut health
… per pen and 10 replicate pens per treatment. A 3-phase feeding program was used with d 0 to 8 as phase 1, d 8 to 21 as phase 2, and d 21 to 34 as phase 3. Within each phase, the 4 diets were supplemented with 0, 90, 180, or 360 mg IQ/kg complete diet. There were no effects of IQ on overall growth …

Use of feed technology to improve nutritional value of feed ingredients fed to pigs
… study indicated that for the overall nursery phase, feeding meal diets instead of pelleted diets increased (P < 0.001) ADFI and decreased (P < 0.05) G:F. However, no difference between the 2 sources of DDGS were observed on average daily gain of weanling pigs. For the entire growing-finishing …

Feeding high oleic soybean oil to growing-finishing pigs: effects on growth performance, carcass characteristics, loin quality, and bacon attributes
… of this project was to evaluate the effects of feeding high oleic soybean oil (HOSO) to growing-finishing pigs on growth performance, carcass characteristics and yield, loin quality and shelf life, and fat and belly quality. A total of 288 pigs raised in two equal blocks were assigned to 1 of 4 …

Effects of dietary fat and protein from corn coproducts on growth, carcass characteristics, ruminal metabolism, and genomic regulation of marbling development in early-weaned beef cattle
… data were collected at the end of each 112d feeding phase. Carcass data included HCW, LM area (LMA), 12th rib back fat (BF), marbling score (MS), KPH, and USDA QG. No interactions (P ≥ 0.27) of fat and protein concentration were detected; therefore, main effects are discussed. No effects (P ≥ …
