  • The effect of fat supplementation of high calcium (Ca) diets on the performance, intestinal pH, body composition and size and weight of organs in growing chickens were investigated in two experiments. Growing chickens tolerated a high dietary level of Ca (22.5 vs 12.1 g/kg) in the presence of 6.3 g/kg of available phosphorus without any significant effect on performance. Intestinal pH was significantly increased by the addition of excess Ca and fat which probably created the right pH for the formation of insoluble Ca soaps. Excess dietary Ca increased carcass linoleic acid concentration at the expense of palmitic and stearic acid contents, whilst the addition of sunflower oil (80 g/kg diet) to the diet increased carcass linoleic acid concentration at the expense of palmitic acid content of the carcass. Intestinal and visceral organ size and weight were not influenced by excess Ca or fat. However, there was a non significant increase in the intestinal dry weight per unit of length caused by excess dietary Ca. It was concluded that excess dietary Ca of 22.5 g/kg did not significantly influence the performance of meat chickens. However, excess Ca increased intestinal pH and altered carcass fatty acid composition. Fat supplementation did not alter intestinal pH with high Ca diets. Excess dietary fat altered carcass fatty acid composition and reduced protein content. Intestinal and visceral organ size and weights were not influenced by excess dietary levels of Ca of fat.

  • An 11-year-old castrated male Maltese had vomiting, diarrhea, and abdominal distension for over two weeks and weight loss for several months. Clinical laboratory studies were not remarkable. Abdominal radiographs showed severe dilated intestine with a gravel sign. Colon was empty with normal diameter in the pneumocolon study. On ultrasonographs, most small bowel loops were dilated without normal peristalsis and showed abnormal thin wall. Barium contrast study revealed remarkably delayed gastric emptying and transit time up to $6^{th}$ day. On exploratory laparotomy, there were no mechanical obstruction and extra-intestinal abnormalities except severe dilated small intestine. Chronic fibrosing lymphohistiocytic leiomyositis with atrophy of tunica muscularis in the small intestines and colon was identified through full thickness biopsy and histopathology. Therefore, primary myopathic chronic intestinal pseudo-obstruction was diagnosed. This dog is survival with symptomatic treatments for eight months.

  • The objects of this experiment was to investigate the effect of dietary several supplemental probiotics on performance and intestinal microflora of Lohmann brown laying hens from 68 to 80 weeks. Basal diets based on corn and soybean meal contained 18.0% CP and 2,720㎉/kg ME. Bacillus subtilis, Lactobacillus salvarius isolated from piglet(LSP) were fed at the level of 0.1 and 0.2% in a one way design. There were four replicates of 40 hens each per treatment. Egg production, feed intake, feed conversion ratio(FCR), eggshell quality were measured at every four weeks and intestinal microflora were examined at the end of experiment. Egg production of bird fed 0.2% individual probiotics was significantly higher than that of control(P 0.05). Birds fed the diet containing 0.2% LSC and LSP had significantly lower FCR than other treatments(P 0.05). However, egg weight of birds fed control and 0.2% BS diet showed higher than other treatments. Feed intake of 0.2% BS and 0.1% LSP treatment was significantly higher than other treatments, but was not consistency of all treatments(P 0.05). Eggshell breaking strength and thickness of hens fed probiotics tended to increase compared to that of control, but was not significantly different. Intestinal anaerobes, Lactobacillus spp. and yeast of hens fed all tested probiotics were significantly increased compared to those of control. The number of intestinal E. coli of all probiotics treatments except 0.1% LSP tended to decrease. Intestinal Lactobacillus spp. was increased significantly by 0.1% dietary LSC, whereas intestinal yeast showed significant increase in LSP treatments(P〈0.05). The results of this experiment indicated that feeding probiotics to laying hens improved the egg production, FCR and increased beneficial microflora.

  • A 4-year-old intact male, Maltese dog weighing 2.2 kg was presented for evaluation of tachypnea and hyperthermia. On initial evaluation, the dog was dyspneic, but alert and responsive. Muffled heart sound was noted with auscultation of the right hemithorax. The radiographic findings were consolidation of the right middle lung lobe, pleural effusion, and abdominal fluid accumulation. Thoracic computed tomography confirmed a contrast-enhancing mass within the right middle lung lobe. Surgical exploration of the thoracic cavity was performed using a right fifth intercostal thoracotomy. Examination of the right lung lobe revealed $360^{\circ}C$ torsion of the right middle lung lobe at the level of the hilus, in a clockwise direction. Lung lobectomy was performed using a thoracoabdominal stapling device with 2.5-mm vascular staples. Full-thickness intestinal biopsy by exploratory laparotomy was taken from the jejunum for histological assessment. Histopathologic examination of the full-thickness intestinal biopsy revealed distended lacteal located within the submucosa of the jejunum. Intestinal lymphangiectasia was resolved with prednisone and low fat diets. Subsequent communication with the owner revealed that the patient was in good health 6 months post-discharge.

  • This experiment examined the effect of dietary spray-dried bovine colostrum on intestinal histology and organ weights in early-weaned pigs. In a randomised complete block design, twelve 14-day-old weaner pigs were offered a diet containing either 5% spray-dried bovine colostrum or no colostrum (control). Diets were formulated to contain 14.8 MJ/kg DE, 1.26% available lysine and to meet or exceed requirements for other nutrients. Piglets were offered the diets for a period of 14 days. No effect of diet on growth rate or feed intake was observed (p>0.10). Small intestine weight was reduced by 12% in piglets consuming dietary bovine colostrum (p< 0.05). Villous height and crypt depth were increased and decreased, respectively, in the proximal jejunum, mid jejunum and distal ileum of pigs consuming dietary bovine colostrum (p<0.05). Mid-jejunal lamina propria $CD4^+$ and $CD8^+$ T lymphocyte density was increased by 28 and 37%, respectively, in piglets consuming dietary bovine colostrum (p<0.05). Diet did not affect thickness of tunica muscularis externa or tunica submucosa (p>0.10). Collectively, these results suggest a positive effect of dietary bovine colostrum on intestinal morphology and immune status in early-weaned pigs.

  • Experiment was conducted to study the effect of sources of dietary fiber on the intestinal morphology of geese. Sixty white Roman geese of two-week-old were divided randomly into six groups and were fed with isoenergetic and isonitrogenous diets which contain alfalfa meal, barley hull, rice hull, purified cellulose, lignin, or pectin as the major dietary source of fiber. Different sources of dietary fiber significantly influenced the villi height and the crypt depth in the duodenum, and the villi height and the muscle layer thickness in the ileum (p < 0.05). The duodenal villus in the geese that fed diets with alfalfa meal, rice hull or pectin supplemented were significantly longest ($968.5{\mu}m$), whereas the lignin group was significantly shortest villus and deepest crypt depth (p < 0.05). The thicknesses of the ileal and caecal muscle layer were significantly thicker in the geese fed with cellulose supplemented diets than in those fed with the other treatment diets. The caecum of the barley bran fed geese possessed significantly longest villi and the most thick muscle layers (p < 0.05). From scanning electronic microscopic observation, the leafy and plate-like in the duodenal villi morphology of geese represented a more effective nutrient absorption in the small intestine. The morphology of ileal villi in geese was similar from herbivorous rabbit and from the African Green monkey.

  • Microcapsule of Propranolol HCl with Cellulose Acetate Phthalate (CAP) by coacervation-phase separation method was studied. Encapsulation was carried out in the CAP-liquid paraffin-acetone ethanol solvent system. The optimum weight ratio for microencapsulation in the CAP-liquid paraffin-solvent system was 1.32:89.18:9.50 or 1.65:89.42:8.93. The wall thickness of microcapsules increased according to increasing of CAP concentration, but dissolution rate decreased. The dissolution of propranolol-HCl in simulated gastric and intestinal fluid test solution was completed within 3 min., but T50% of propranolol HCl from 10.0% CAP-microcapsules were 390 min. and 210 min. respectively. The released amount from 12.5% CAP-microcapsules was 41.8% within 720 min. in simulatd gastric fluid test solution and T50% of those in simulated intestinal fluid test solution was 250 min.

  • Objective: Diet acidification supplementation is known to influence intestinal morphology, gut microbiota, and on phosphorus (P) utilization of broilers. Alterations in intestinal barrier and microbiota have been associated with systemic inflammation and thus regulating bone turnover. Hence the effect of acidifier addition to drinking water on tibia mass and the linkages between intestinal integrity and bone were studied. Methods: One-d-old male broilers were randomly assigned to normal water (control) or continuous supply of acidified water (2% the blend of 2-hydroxy-4-methylthiobutyric acid, lactic, and phosphoric acid) group with 5 replicates of 10 chicks per replicate for 42 d. Results: Acidification of drinking water improved the ash percentage and calcium content of tibia at 42 d. Broilers receiving acidified water had increased serum P concentration compared to control birds. The acidified group showed improved intestinal barrier, evidenced by increased wall thickness, villus height, the villus height to crypt depth ratio, and upregulated mucin-2 expression in ileum. Broilers receiving drinking water containing mixed organic acids had a higher proportion of Firmicutes and the ratio of Firmicutes and Bacteroidetes, as well as a lower population of Proteobacteria. Meanwhile, the addition of acidifier to drinking water resulted in declined ileal and serum proinflammatory factors level and increased immunoglobulin concentrations in serum. Concerning bone remodeling, acidifier addition was linked to a decrease in serum C-terminal cross-linked telopeptide of type I collagen and tartrate-resistant acid phosphatase reflecting bone resorption, whereas it did not apparently change serum alkaline phosphatase activity that is a bone formation marker. Conclusion: Acidified drinking water increased tibia mineral deposition of broilers, which was probably linked with higher P utilization and decreased bone resorption through improved intestinal integrity and gut microbiota and through decreased systemic inflammation.
