Effect of dietary methionine on performance, carcase characteristics and breast meat composition of heterozygous naked neck (Na/na+) birds under spring and summer conditions

PubMed ID: 106706831. Heteroxygous naked neck (Na/na+) birds and their normally feathered counterparts (na+/ na+) were fed from 0 to 7 weeks on 3 diets differing in methionine concentrations. From 0 to 3 and 3 to 7 weeks, respectively, the concentrations were: low containing 4.3 and 3.3 g/kg; optimum containing 5.0 and 3.8 g/kg and; high with 5.7 and 4.4 g/kg under spring (optimum ambient temperature) and summer conditions (high ambient temperature). Performance, carcase characteristics and breast meat chemical composition were determined. 2. Summer rearing resulted in a decrease in body weight, body weight gain, food consumption, and yields of carcase and breast. The summer temperature effect was more pronounced in males. Under summer temperatures, the protein content of the breast decreased while the fat content increased compared to birds reared in spring. 3. By 7 weeks of age, both genotypes reached similar body weights in the spring experiment while, in summer Na/na+ birds were 3.3% heavier and gained more in the period from 3 to 7 weeks than na+/na+ birds. Carcase and breast yields of Na/na+ birds were greater than in na+/na+ birds. 3. Second order polynomial coefficients of the dietary methionine effect were found to be significant for body weight at 3 and 7 weeks. Daily body weight gain between 3 and 7 weeks was linearly affected by the dietary methionine concentration. There was no interaction between genotype and methionine. 4. Methionine had no significant effect on carcase yield. Second order polynomial coefficients of the dietary methionine effect were found to be significant for breast yield while the methionine effect on abdominal fat was linear. Na/na+ females fed on the low methionine diet had lower protein content than the Na/na+ males. 5. It is concluded that the methionine requirement of Na/na+ birds did not differ from that of their normally feathered counterparts under either spring or summer ambient temperature conditions. © 1999 British Poultry Science Ltd

Effect of cumin essential oil on intestinal morphology of broilers reared in a free-range system

The relationships between small intestine morphological values and body weight gain of slow-growing broilers with cumin essential oil (CEO) added to their diets at different levels and raised in a free-range system were investigated. A total of 450 slow-growing, 1-day-old chicks were used. The animals were divided into three groups and fed with 0 ppm (control group), 200 ppm (C200 group), or 400 ppm (C400 group) CEO added to their feed for 70 days. According to the results of the morphological analysis, while diets with CEO decreased the villus and crypt dimensions in the duodenum and ileum, they decreased only villus dimensions and the ratio of villus height to crypt depth in the jejunum. The morphological parameters of the small intestine showed positive correlations with each other in all groups and were found to be statistically significant. However, differences were observed in the correlations between body weight gain and morphological intestinal parameters. Body weight gain, villus width, and crypt depth in the control group were positively correlated, while the same traits tended to show negatively correlations in the C200 and C400 groups, but not in a statistically significant manner. It was concluded that 200 and 400 ppm CEO added to the feed of slow-growing broilers raised in a free-range system have a suppressive effect on the morphological parameters of the small intestine and, according to correlation analyse, it has a slowing effect on body weight gain. © 2023, Verlag Eugen Ulmer.

CTX-M-3 extended-spectrum beta-lactamase in a Shigella sonnei clinical isolate: First report from Turkey

A Shigella sonnei strain resistant to cefotaxime and aztreonam (but not ceftazidime) was isolated from the stool sample of a 7-y-old outpatient. Double disk synergy test, isoelectric focusing, polymerase chain reaction and sequence analysis confirmed that the isolate produced CTX-M-3, an extended-spectrum beta-lactamase (ESBL). This is the first report from Turkey of Shigella spp. producing an ESBL, and of CTX-M type enzyme

Nocardia farcinica brain abscess: a case report and review of the literature

WOS: 000227230100015PubMed: 15632997Nocardia infection is not rare as generally been assumed and its mortality rate is high. It is isolated from plants and soil in most regions of the worid. The hosts usually have predisposing conditions and the infection is acquired through the respiratory tract or skin. Nocardial organisms have a tendency to disseminate hematogenously from the primary site of infection to brain, kidney, joints, bones and eyes. Sulfonamides are preferred empirically for the treatment. Because of high relapse rates, the treatment must be continued for 12 months. In nocardia farcinica infection, the characteristic resistance pattern to cephalosporines must be kept in mind. In this article, a rare case of nocardia farcinica infection with a solitary cerebral abscess is presented and the literature is reviewed

Giant unruptured anterior communicating artery aneurysm presenting with seizure

Giant aneurysms of the anterior communicating artery (AComA) are rare. The clinical presentation of giant AComA aneurysms is usually associated with the mass effect of the space-occupying lesion or with subarachnoid haemorrhage. A giant AComA aneurysm presenting with a seizure has only been reported twice previously. We report a 70-year-old female patient, in whom a single seizure was the only symptom of a giant AcomA aneurysm, with no neurological deficit. The diagnosis of unruptured giant AComA aneurysm was made with cranial CT, MRI and angiography. The patient refused surgical intervention, was treated with anti-epileptic therapy and has been asymptomatic for 7 months. We suggest that elderly patients presenting with a first seizure need detailed evaluation and giant aneurysms, which may be confused with other intracranial space-occupying lesions, need to be considered in the differential diagnosis. © 2006 Elsevier Ltd.

Experimental bile-duct ligation resulted in accumulation of oxidized low-density lipoproteins in BALB/c mice liver

Background and Aim: Oxidized low-density lipoproteins (LDL), which are produced during oxidative stress by the process of lipid peroxidation, have also been proposed to have complex roles in many other immuno-inflammatory mechanisms. It has been shown that bile-duct ligation results in oxidative stress in the liver of animals. The aim of this study was to investigate if oxidized LDL are produced in the liver tissues of bile-duct-ligated mice. Methods: Obstructive jaundice was induced in BALB/c mice by the ligation and division of the common bile duct. Liver concentrations of glutathione and malondialdehyde were measured in the sham-operated (n = 10) and bile-duct-ligated (n = 10) mice on the 10th day of obstructive jaundice. The presence of oxidized LDL in the liver tissue sections was evaluated using a special, novel immunofluorescent staining method. The final step was to explore the existence of oxidized LDL under fluorescent microscopy. Results: Compared with sham-operated mice, jaundiced mice showed significantly higher levels of malondialdehyde and lower concentrations of reduced glutathione in the liver. While there was no staining in the sham-operated group, bile-duct ligation resulted in positive oxidized LDL staining in the liver tissues of mice. The present study testifies that bile-duct ligation results in oxidative stress and enhanced lipid peroxidation in the hepatic tissues of BALB/c mice and moreover, that oxidized LDL accumulate in the liver of mice with experimental obstructive jaundice. Conclusion: Oxidized LDL may be an important and direct indicator of ongoing oxidative stress and enhanced lipid peroxidation in obstructive jaundice. The potential roles of this finding were also discussed, briefly. © 2004 Blackwell Publishing Asia Pty Ltd

Forage yield and lodging traits in peas (Pisum sativum L.) with different leaf types

Two semi-leafless and four leafed pea (Pisum sativum L.) genotypes were evaluated for plant height, lodging scores, and forage yield in eight diverse locations with typical Mediterranean or Mediterranean-type climate in the 2001-2002 and 2002-2003 growing seasons. The genotypes used in this study were forage type with indeterminate growing habit. Significant differences among pea genotypes were found for all traits over years and locations. All interactions which related to G × E interaction showed significance (P>0.01) for all traits. The forage yield of the pea genotypes averaged 26605 kg ha-1 and the highest yield was obtained from the leafed genotype Urunlu. Its forage yield reached to 35970 kg ha-1 yield level at Samsun location
