Three types of bamboo pellets as a ruminant feed: P1 (ground bamboo (GB) cultured with the fungus Ceriporiopsis subvermispora (CGB) : soybean curd residue (T) : soy sauce cake (S) in a 5:4:1 ratio on a dry matter (DM) basis); P2 (GB : T : S = 5:4:1 on a DM basis); and P3 (CGB : T : S = 5.5:0.8:3.7 on a DM basis) were prepared. Four wethers were assigned in a 4 × 4 Latin square design experiment to evaluate the applicability of the bamboo pellets. The experimental treatments were C (control): fed alfalfa hay cubes (AC) only, and T1, T2 and T3: fed P1, P2, and P3 with AC by 1:1 on a DM basis, respectively. The digestibility of the DM, organic matter and acid detergent fiber of P1 were significantly higher than those of P2 and P3 (P < 0.05). The total digestible nutrient (TDN) contents of AC, P1, P2 and P3 were 56.5%, 60.2%, 53.2% and 47.0%, respectively. No significant differences in nitrogen retention or ruminal pH and NH3 were observed among the treatment groups. The results indicate that bamboo pellets cultured with C. subvermispora and mainly mixed with soybean curd residue improved nutritional quality of ground bamboo because of its high digestibility and TDN content. 相似文献

1. The genetic architecture of the avian uncoupling protein (avUCP) was investigated and the relationship between avUCP gene expression and the amount of abdominal fat of Japanese quail was determined by quantitative real-time PCR. 2. The Japanese quail avUCP gene consists of six exons and five introns. Sequences of nucleotides and amino acids were 94·6% and 86·0% identical to those of the chicken avUCP gene, and phylogenetic analysis showed that the Japanese quail avUCP gene consists of the same clusters as the chicken and turkey avUCP. 3. Expression of the avUCP gene was significantly higher in the Pectoralis major (1·28?±?0·24) than in the Biceps femoris (0·63?±?0·14). 4. A positive correlation coefficient between the avUCP gene expression in the Pectoralis major and Biceps femoris was observed (r?=?0·79, P?=?0·02), whereas a negative correlation coefficient was observed between the abdominal fat percentage (AFP) and gene expression in both the Pectoralis major (r?=??0·82, P?=?0·01) and Biceps femoris (r?=??0·61, P?=?0·11). 5. The avUCP gene was associated with the accumulation of abdominal fat in Japanese quail and it was concluded that modulation of avUCP gene expression could be utilised to control abdominal fat accumulation in poultry. 相似文献

The first joint Japanese Society of Toxicologic Pathology (JSTP) and National Toxicology
Program (NTP) Satellite Symposium, entitled “Pathology Potpourri,” was held on January
29th at Okura Frontier Hotel in Tsukuba, Ibaraki, Japan, in advance of the
JSTP’s 29th Annual Meeting. The goal of this Symposium was to present current
diagnostic pathology or nomenclature issues to the toxicologic pathology community. This
article presents summaries of the speakers’ presentations, including diagnostic or
nomenclature issues that were presented, select images that were used for audience voting
or discussion, and the voting results. Some lesions and topics covered during the
symposium include: treatment-related atypical hepatocellular foci of cellular alteration
in B6C3F1 mice; purulent ventriculoencephalitis in a young BALB/c mouse; a subcutaneous
malignant schwannoma in a RccHan:WIST rat; spontaneous nasal septum
hyalinosis/eosinophilic substance in B6C3F1 mice; a rare pancreatic ductal cell adenoma in
a young Lewis rat; eosinophilic crystalline pneumonia in a transgenic mouse model; hyaline
glomerulopathy in two female ddY mice; treatment-related intrahepatic erythrocytes in
B6C3F1 mice; treatment-related subendothelial hepatocytes in B6C3F1 mice; spontaneous
thyroid follicular cell vacuolar degeneration in a cynomolgus monkey; congenital hepatic
fibrosis in a 1-year-old cat; a spontaneous adenocarcinoma of the middle ear in a young
Crl:CD(SD) rat; and finally a series of cases illustrating some differences between
cholangiofibrosis and cholangiocarcinoma in Sprague Dawley and F344 rats. 相似文献

GM2 gangliosidosis variant 0 (human Sandhoff disease) is a lysosomal storage disease caused by simultaneous deficiencies of acid beta-hexosaminidase (Hex) A and Hex B due to an abnormality of beta-subunit, a common component in these enzyme molecules, which is coded by the HEXB gene. In the present study, a retrospective diagnosis was performed in 2 previous suspected cases of feline Sandhoff-like disease using a DNA test to detect the causative mutation identified previously in 4 cats in 2 other families of Japanese domestic cats. Enzymic analysis was also performed using stored leukocytes and plasma collected from the subject families in order to investigate the usefulness of enzymic diagnosis and genotyping of carriers. The DNA test suggested that the 2 cases were homozygous recessive for the mutation. Consequently, 6 cats homozygous for the same mutation have been found in 4 separate locations of Japan, suggesting that this mutant allele may be spread widely in the Japanese domestic cat populations. In enzymic analysis, Hex A and Hex B activities in leukocytes and plasma measured using 4-methylumbelliferyl N-acetyl-beta-D-glucosaminide as a substrate were negligible in affected cats, compared with those in normal and carrier cats. However, there was a wide overlap in enzyme activity between normal and carrier cats. Therefore, it was concluded that enzymic analysis is useful for diagnosis of affected cats, but is not acceptable for genotyping of carriers. 相似文献

Despite the immense socio-economic repercussions of African trypanosomosis (AT), there is currently no effective control measure against the disease. Characterization of mechanisms governing resistance and/or susceptibility to AT could suggest interventions that might lead to more effective disease control. The present study was designed in an attempt to address the possible role of CD4+CD25+ T cells during an acute lethal infection of mice with Trypanosoma congolense, the causative agent of AT in domestic animals, through selective depletion using anti-CD25 monoclonal antibody. Accordingly, CD4+CD25+ T-cell-depletion resulted in a significant reduction or delay in parasitemia, pathology, and mortality, as compared to controls. The apparent resistance in CD4+CD25+-T-cell-depleted mice correlated with a profound suppression of Th2 cytokines in vitro and in vivo, culminating in a net Th1 cytokine environment. Cumulatively, these findings suggest that CD4+CD25+ T-cell- depletion improves the trypanotolerance of highly susceptible BALB/c mice acutely infected with the lethal T. congolense. 相似文献

To study the effect of ionizing radiation on thyroid glands, 66 Japanese Black cattle residing in the restricted area of the Fukushima Daiichi Nuclear Power Plant in 2013–2017 were pathologically examined. There were no clinical symptoms of thyroid disease in these cattle. Three cases of goiter and seven of atrophy were found in two among the four farms examined. Cases of goiter exhibited normal morphological structure without mass or nodule formation in thyroid glands. Cellular atypia or capsular invasion of the follicular epithelium was absent. The estimated integrated dose of external radiation in goiter cases ranged from maximum 797 mSv to minimum 24 mSv. All lobules in the seven atrophic thyroid glands were affected, but pathological findings, such as inflammatory cell infiltration or stromal fibrosis, were not observed. The estimated integrated dose of external radiation in atrophic thyroids ranged from maximum 589 mSv to minimum 8 mSv. Immunohistochemical analysis of anti‐nitroguanosine and the TUNEL method in goiter and atrophic thyroid glands did not reveal any positive findings. The present study indicates that there was no significant relationship between a radiation effect and pathological findings in any thyroid glands. 相似文献

Blood and urine were compared to clarify which is a better sample for estimating the concentration of radioactive cesium in muscles of live cattle. The most probable concentration of 137Cs in muscles was 21.0 times that in blood, and the error of this estimation was 28%. The concentration of 137Cs in blood was estimated accurately using urine samples. The estimation error did not increase so much (33%), even when the concentration of 137Cs in muscles was estimated using urine samples. On the other hand, the maximum volume of blood that can be collected with one syringe is 50 ml, whereas it is easy to collect 1,000 ml of urine. It took at least 360 min to confirm that a cow meets the legal standard by inspecting 50 ml of blood. However, with 1,000 ml of urine, a 20 min measurement time was sufficient for this purpose. This difference in the required measurement time is critically important for practical use. In addition, urine can be collected by farmers themselves, whereas the blood collection requires a veterinarian. Therefore, urine is a more convenient and practical sample for estimating the contamination level of live cattle with radioactive cesium. 相似文献

We investigated the environmental factors in Japan, including meteorological conditions, on the fertility of a European cattle breed, Holstein–Friesian, by examining conception rates in different regions. First artificial insemination and associated conception details were recorded for 69,952 Holstein female cattle. In general, meteorological conditions vary considerably according to latitude in Japanese islands. Conception rates were higher in the Northern (above 37°N) than the Southern (below 37°N) region (61.3% vs. 53.3%). All the factors analyzed in the statistical model, including insemination year, region, month, AI technician, service sire and interaction between region and month, had significant effects on the conception rate. In the Southern region, conception rates were lower in the summer months (average temperature, 27.8 °C, and maximum temperature, 32.3 °C). However, this seasonal decline was not observed in the Northern region (average temperature, 23.7 °C, and maximum temperature, 28.4 °C). Regression analysis of conception rate in relation to temperature showed highly significant negative regression coefficients (− 0.66 to − 0.63% per °C; p < 0.001) in the Southern region, but non-significant coefficients in the Northern region. Humidity had a minimal effect on conception rate in both regions. Our data collectively suggest that 37°N latitude is a threshold that affects Holstein–Friesian conception rates in Japan. 相似文献
