Motor laterality in 4 breeds of dog     

Paul D. McGreevy  Alex Brueckner  Peter C. Thomson  Nicholas J. Branson 《Journal of Veterinary Behavior: Clinical Applications and Research》2010,5(6):318-323

The aim of the current study was designed to explore possible breed differences in a basic behavioral phenotype in dogs. It measured paw use during food-retrieval from a cylindrical, hollow, rubber toy to assess motor laterality (pawedness) in 4 breeds of dogs selected for their morphological differences: 45 greyhounds (males n = 23/females n = 22), 47 whippets (15/32), 46 pugs (15/31), and 45 boxers (17/28). A laterality index was calculated from the use of individual paws to restrain the toy during feeding. An association was found between sex and the laterality index (P = 0.035), reflecting a significant bias for left-paw use by entire male dogs and right-paw use by entire female dogs but no sex difference was found in the mean strength of laterality. No significant association was found between age and the laterality index. No breed difference was found in the laterality index (P = 0.423) or the absolute strength of laterality (i.e., the laterality index without direction, P = 0.259). However, important breed differences in the use of the test device emerged. The frequency of simultaneous use of both paws was lowest in pugs (P < 0.0001). In addition, both brachycephalic breeds (pugs and boxers) took less time than the dolichocephalic breeds (the whippets and greyhounds) to complete the criteria of 100 paw-use scores that was set for the laterality test. The absence of breed differences in the laterality index for paw use suggests that the task is a reliable measure of motor laterality in dogs during a food-retrieval task.  相似文献   

Original Study: Comparison of three intraosseous access techniques in cats

Objective – To compare the placement feasibility and amount of bone trauma induced by 3 intraosseous (IO) access techniques in cats: an automatic impact penetration device (A), an automatic rotary insertion device (B), and a manual IO needle (C). Design – Prospective ex vivo study. Setting – University. Animals – Eighteen adult mixed breed feline cadavers. Interventions – Cadavers provided 72 total IO insertion locations divided equally between the right and left humerus and tibia. The 3 IO techniques were randomly allocated to these locations. Time to successful insertion, ease of insertion, and success rate were recorded. Each insertion site was analyzed for the number of bone fragments and defect diameter by computed tomography. Measurements and Main Results – Device B had lower time of insertion (P=0.01) compared with devices A and C. Device B had better ease of insertion scores (P<0.01) compared with devices A and C. No differences were detected between insertion sites (tibia versus humerus). No differences in the number of bone fragments, defect diameter, or success rate were detected among devices (P=0.06, 0.31, and 0.14, respectively). Conclusions – All 3 IO access methods evaluated yield acceptable results. Device B is significantly faster and easier to place in cat cadavers when compared with other methods.  相似文献   

Willingness of residents to pay and motives for conservation of urban green spaces in the compact city of Hong Kong     

Alex Y. Lo  C.Y. Jim 《Urban Forestry & Urban Greening》2010,9(2):113-120

People attach multiple values to urban green spaces which play varied roles in cities. Properly designed monetary valuation surveys can ascertain their non-market value and underlying motives. This study investigates Hong Kong residents’ recreational use of urban green spaces and assesses the monetary value of these areas. A total of 495 urban residents from different neighbourhoods and socio-economic groups were interviewed. About 70% of the respondents visited urban green spaces at least weekly. Major companions during patronage were family members and then children. Exercises and clean air topped the list of visit purposes. The recreational pattern is associated with the cramped private living condition that pushes people to public open areas which are construed as extension of home space. The valuation question solicited overwhelming support, with over 80% of the respondents willing to pay to recover a possible loss of urban green spaces area by 20%. It yielded a monthly average payment of HK$77.43 (approx. 9.90 USD) per household for five years. Non-instrumental aspects played some role in the respondents’ bidding decision. The findings could assist green space planning and nature conservation, and hinted the need to consider the pluralistic community views and expectations in relevant public policies.  相似文献

A total of 750 faecal samples of dairy calves at up to 2 months of age kept in various housing systems were screened for Cryptosporidium spp. infection using the aniline-carbol-methyl violet staining method. DNA was extracted from Cryptosporidium positive samples and from 150 randomly selected microscopically negative samples. Nested PCR was performed to amplify the partial SSU rRNA gene of Cryptosporidium that was subsequently digested by SspI, VspI and MboII restriction enzymes to determine the present Cryptosporidium species and genotype. In addition, the samples characterized as Cryptosporidium parvum were subsequently analyzed at the GP60 gene to determine the distribution of zoonotic subtypes. Sequence analyses and RFLP identified C. parvum in 137, Cryptosporidium andersoni in 21 and Cryptosporidium bovis in 3 samples. Neither mixed infections nor Cryptosporidium ryanae was detected. Sequencing of the GP60 gene from C. parvum-positive samples revealed all five subtypes of family IIa (A15G2R1, A16G1R1, A22G1R1, A18G1R1, and A15G1R1). The obvious management-associated distribution of Cryptosporidium spp. was demonstrated. Direct contact with adult animals was found to be a risky factor for C. andersoni and C. bovis infection. IIaA15G2R1 and IIaA16G1R1 were detected as major subtypes, whereas only the IIaA16G1R1 subtype was found in animals kept in boxes. Three of the five detected subtypes were previously associated with human cryptosporidiosis, and moreover, the IIaA15G1R1 subtype, previously reported in humans only, was detected in calves for the first time.  相似文献

Kisspeptins, a family of neuropeptide encoded by the Kiss1 gene, have emerged as crucial regulator of fertility and reproduction by regulating the hypothalamic–pituitary–gonadal axis. The present study was aimed to identify and associate SNPs in the KISS1 gene with reproductive traits in cattle of Indian origin. DNA samples collected from 300 individual cows of three Indian dairy breeds (Gir, Kankrej and Frieswal) of cattle were used in the study. The SNPs of KISS1 gene were identified with PCR-RFLP and sequence analysis using two sets of primer pairs. A total of 5 SNPs were identified in the targeted region of which, two were selected for screening the population and association studies. The analysis revealed that genotypes of rs442633552G>A and rs42022871C>T had a significant association with dry period. The SNP rs42022871C>T also established significant role in milk production traits, and selection of TT-genotyped animals will improve the reproduction and production potential of the animals.  相似文献
