Results The SID of CP in the barley, lupin kernels, wheat, 2 sources of corn gluten feed, corn gluten meal, lupin hulls, rice bran, soybean meal, and wheat bran were 84.7, 90.5, 90.4, 77.4, 74.6, 89.5, 90.4, 74.4, 86.9, and 63.4% [standard error of the mean (SEM) = 5.3, p=0.006], respectively. The respective SID values of Lys were 75.5, 88.4, 83.9, 74.7, 62.4, 80.3, 83.9, 78.5, 88.0, and 71.2% (SEM = 3.3, p less then 0.001), and the SID values of Met were 83.6, 88.7, 89.4, 85.7, 78.3, 88.9, 89.4, 85.3, 91.1, and 77.0% (SEM = 2.4, p less then 0.001), respectively. Conclusion The ileal digestibility of protein and amino acids varies among the feed ingredients fed to pigs.Objective This study was carried out to investigate the effects of dietary probiotic blend and liquid feed program at different nutritional densities on growth performance, nutrient digestibility, fecal score of weaning piglets. Methods A total of 120 weaning pigs with an initial BW of 7.05 ± 0.93 kg per pig (21 days of age) were randomly allocated into 1 of the following 8 dietary treatments (3 replicates per treatment with 5 pigs per replicate) in a 2×2×2 factorial arrangement with 2 levels of nutrition density (AME=14.63 kJ/kg or 3500 kcal/kg, CP=20% VS AME=14.23 kJ/kg or 3400 kcal/kg, CP=19.42%), 2 types of feed (dry VS wet) and 2 levels of probiotics (0 mg/kg VS 300 mg/kg). There were 8 experimental diets TRT1, high nutrition × dry type without probiotics; TRT2, high nutrition × dry type with probiotics; TRT3, high nutrition × wet type without probiotics; TRT4, high nutrition × wet type with probiotics; TRT5, low nutrition × dry type without probiotics; TRT6, low nutrition × dry type with probiotics; TRT7, low nutrition × wet type without probiotics; TRT8, low nutrition × wet type with probiotics. This research was divided into three periods Phase 1 0-5days; Phase 2 5-15days; Phase 3 15-25 days. All the response criteria were measured at the end of each phase. Results In the phase 2, ADG and ADFI were greater (P0.05). Conclusion These results indicated that probiotics in a supplementation diet could benefit growth performance (ADG, ADFI and GF) and reduce the frequency of watery feces. Besides, wet feed program (feed water=11.25) could improve the GF. Because there were two positive interactions one between liquid program and nutrition density, the other between supplementation probiotics and nutrition density, the effect of liquid feed or probiotic could be influenced by dietary nutrition density in weaned piglets. An increased value of G F was obtained when wet feeding a high nutrition diet (100 kcal higher than NRC 2012 recommendations) was supplemented with probiotics for 15 to 25 days.Objective A total of three hundred unsexed ducks were conducted to estimate net energy requirements of maintenance (NEm) and weight gain (NEg) for 2 to 3-week-old Cherry Valley ducks and to establish a model equation to predict net energy requirements using the factorial method. Methods To determine the apparent metabolizable energy (AME) of the diet, fifty 7-day-old ducks at approximately equal body weights (BWs) were randomly assigned into five groups that were fed at different levels (ad libitum, 85%, 75%, 65%, and 55% of ad libitum intake), and the endogenous acid-insoluble ash (AIA) as indigestible marker. The two hundred and fifty 7-day-old ducks were used for a comparative slaughter experiment. At the beginning of the experiment, ten ducks were sacrificed to determine the initial body composition and energy content. The remaining ducks were randomly assigned into five groups (same as metabolic experiment). Ducks of the ad libitum group were slaughtered at 14 and 21-day-old. At the end of the experiment, two ducks were selected from each replicate and slaughtered to determine the body composition and energy content. Results The results of the metabolizable experiment showed AME values of 13.43 to 13.77 MJ/kg for ducks at different feed intake. The results of the comparative slaughter experiment showed the NEm value for 2 to 3-week-old Cherry Valley ducks was 549.54 kJ/kg of BW0.75/d, and the NEg value was 10.41kJ/g. The deposition efficiency values of fat (Kf) and crude protein (Kp) were 0.96 and 0.60, respectively, and the values of efficiency of energy utilization (Kg) and maintenance efficiency (Km) were 0.75 and 0.88, respectively. Conclusion The equation for the prediction of NE requirements for 2 to 3-week-old Cherry Valley ducks was the following NE = 549.54 BW0.75 + 10.41 ΔW, where ΔW is the weight gain (g).Objective We examined the localization and expression of H+ pumping vacuolar ATPase (V-ATPase) and cytokeratin 5 (KRT5) in the epididymis of pigs, expressed in clear and basal cells, respectively, during postnatal development. Methods Epididymides were obtained from pigs at 1, 7, 21, 60, 120, and 180 days of age; we observed the localization and expression patterns of V-ATPase and KRT5 in the different regions of these organs, namely, the caput, corpus, and cauda. The differentiation of epididymal epithelial cells was determined by immunofluorescence labeling using cell-type-specific markers and observed using confocal microscopy. Results At postnatal day 5 (PND5), the localization of clear cells commenced migration from the cauda toward the caput. Although at PND120, goblet-shaped clear cells were detected along the entire length of the epididymis, those labeled for V-ATPase had disappeared from the corpus to cauda, and were maintained only in the caput epididymis in adult pigs. In contrast, whereas basal cells labeled for KRT5 were only present in the vas deferens at birth, they were detected in all regions of the epididymis at PND60. These cells were localized at the base of the epithelium; however, no basal cells characterized by luminally extending cell projections were observed in any of the adult epididymides examined. ARRY-382 supplier Conclusion The differentiation of clear and basal cells progressively initiates in a retrograde manner from the cauda to the caput epididymis. The cell-type-specific distribution and localization of the epithelial cells play important roles in establishing a unique luminal environment for sperm maturation and storage in the pig epididymis.
