Ehrlichia canis is a tick-borne rickettsia. It can cause canine monocytic ehrlichiosis (CME). Infected dogs are often reported to have changes in their blood values, such as anemia, thrombocytopenia, increased liver enzymes, and increased kidney function values. This study aimed to collect data that may be related to infected dogs, including age, gender, breed, weight, close-open housing system, the use of ectoparasiticides products. The sample comprised 57 infected dogs. Collecting hematology and serum biochemistry changes in comparison with the reference values of dogs detected with Ehrlichia canis from 2017-2019, Thonburi District, Bangkok, Thailand was also carried out. In summary, dogs infected with Ehrlichia canis mostly included mixed-breed dogs aged between 1 and 10 years. There were no differences in body weight or housing systems. Dogs that had never used ectoparasiticide products or used them intermittently were infected more often (by 7.14 times) than protected. Clinical hematology and serum biochemistry found anemia, thrombocytopenia, and increased liver enzymes.

The performance of male and female quails reared separately in cages and on deep litter was investigated. One hundred and eighty 3-week old quails managed for five weeks. There were three replicates per treatment with stocking densities of 120cm2/bird in cage and 180cm2/bird on deep litter and sex as a block factor. Data on weekly body weight, weight change, daily feed and water intakes, feed: gain, carcass yield and costs of production were analysed. Daily water consumed by quails between the housing systems (62.76±11.21mL/d on deep litter vs. 66.96±12.18mL/d in cage system, p>0.05) were same. However, quails housed on deep litter consumed more feed from 43-56 days of age (25.34±1.77g/d vs. 22.99±1.55g/d). Quails reared on deep litter also grew faster during the first week of that period (3.33±1.70g/d vs. 0.69±0.87g/d). However, gain in body weight was noticed from day 22 to day 49 but a sudden decline thereafter for all quails regardless of sex and housing system. Carcass yield was not affected by housing system but values for thighs, empty gizzard and liver of quails kept on deep litter were higher (respectively 12.95±0.86% vs. 11.99±0.83%, 2.12±0.18% vs. 1.84±0.20%, 2.11±0.59% vs. 1.88±0.43%; p<0.05). Production costs were the same (p>0.05) whether on deep litter (3414.30±172.95CFA/kg) or in cages (3283.43±77.72CFA/kg). However, the production cost per kilogram of carcass of male quails was lower compared to females (3205.88±138.95CFA/kg vs. 3484.35±131.57CFA/kg, respectively) regardless of the housing system. Sex and age of quails affect performance and not the type of housing system.

Biting Behaviour

AbstractThe development of adverse behaviour in group–housed growing/ finishing pigs with intact tails was studied in a straw–flow housing system and in a part–slatted system with a commercial enrichment object. Food intake, body weight and behaviour were monitored over the finishing period, with tail biting outbreaks defined as an occasion where three or more pigs within a group had freshly damaged tails and tail biting behaviour was ongoing. Data from the two systems were analysed to identify tail–biting outbreaks and behavioural changes over time. Levels of pig manipulation were higher in the part–slatted system. Over time, pigs in both systems showed reduced interest in the enrichment provided, but not in each other. Despite the presence of the enrichment device, tail biting occurred in all groups in the part–slatted system, but only 1/12 groups in the straw–flow system. The amount of time occupied by manipulation of the enrichment provided was very significantly higher for straw than for the commercial object. Better design of enrichment strategies is therefore needed and should be based on species–relevant requirements.

Environmental conditions, including enrichment and stress, affect animal behaviors, but limited information is available regarding the differences in animal functions between the chamber (ventilated system) vs. IVC (individually ventilated cages) housing systems. Therefore, the effects of different housing systems were examined on physical, emotional, and cognitive functions and the intestinal flora with aging. DBA/2CrSlc mice were divided into chamber and IVC groups. Differences in the structure of the two cages considered whether the mouse could dangle or not. Physical, emotional, and cognitive functions were examined using the open field, black and white box, object recognition, horizontal bar, wire hanging, balancing, footprint, and locomotor tests. The IVC group demonstrated significantly less food intake, higher body weight (by approximately 5 g), lower rectal core temperature, less muscle and balancing powers with aging, and fewer anxiety-like behaviors than the chamber group. No differences were observed in the cognitive function and intestinal microbiota between the groups. The housing environment affected the rodent basal temperature and body weight as well as the physical and emotional functions. Scientists should be attentive to the type of cages used in the housing system for an experiment, especially when comparing the results with animals reared in different systems.

The efficacy of doxycycline treatment (10 mg/kg of body weight every 24 h for 42 days) in eliminating Ehrlichia canisfrom four subclinically infected dogs was evaluated. One dog remained PCR positive, suggesting that 6 weeks of doxycycline treatment may not be sufficient to clear E. canis parasites from all subclinically infected dogs. Serology (indirect immunofluorescent antibody assay) was shown to be unreliable in assessing recovery from the carrier state, as anti-E. canis antibodies persisted after elimination of the parasite. Our findings suggest that an increase in the platelet count may be an important indicator for dogs that recover from subclinical ehrlichiosis.

ABSTRACT This report presents evidence that dogs recover from acute canine monocytic ehrlichiosis (CME) after 16 days of doxycycline treatment (10 mg/kg of body weight every 24 h). Blood PCR was as valuable as splenic aspirate PCR for early diagnosis of acute CME. Splenic aspirate PCR was, however, superior to blood PCR for the evaluation of ehrlichial elimination.

Records of claw trimmings were analysed in seven organic and six conventional Danish herds (a total of 974 cows). The housing systems represented were tie stall systems, loose housing system with slatted floor (one organic herd), and deep litter systems (deep straw bedding). Occurrence of sole disorders was analysed separately for cows in first lactation and for cows in later lactations. Three different responses (acute haemorrhage, sole ulcer in one leg and sole ulcer in two or more legs) were analysed using three binomial logistic regression analyses for each group. Herd analysed as a fixed effect was a strong risk factor for all kinds of sole ulcer. Lactation stage was a risk factor for acute haemorrhage in both groups of cows, and for sole ulcer in first parity cows. In general, there was a strong positive association between the period 61–120 d post partum and the presence of sole disorders. Breed was associated with acute haemorrhage in cows in second and later parities, and sole ulcer in one leg only in first parity cows in an interaction with lactation stage in both conditions. Danish Friesian cows were strongly associated with sole disorder, although the combination of lactation stage from 61 to 120 d post partum in cows of other dual purpose breeds was positively associated with the presence of sole ulcer in one leg only in first parity cows. The time of year for claw trimming was a risk factor for acute haemorrhage in first parity cows, with the period from December to January most strongly associated with acute haemorrhage. Previous disease treatment was a risk factor for sole ulcer in two or more legs in second and later parities. Udder related disorders and disorders other than reproductive problems were positively associated with the occurrence of sole ulcer. Body weight at calving was associated with acute haemorrhage in cows in second and subsequent parities. Body weight lower than the mean herd level by >50 kg was negatively associated with acute haemorrhage.

Abstract. Title of the paper: Evaluation of small group housing systems and furnished cages concerning keel bone deformities, plumage condition, claw length und body weight in layer strains Lohmann Selected Leghorn and Lohmann Brown Small group housing systems (Eurovent 625+a-EU) and furnished cages (Aviplus und Eurovent 625A-EU) were evaluated for the occurrence of keel bone deformities, plumage condition, claw length and body weight. The examinations were performed in two layer strains, Lohmann Selected Leghorn (LSL) and Lohmann Brown (LB), over two laying periods. In addition, the effects of layer strain, month of laying period, rearing method, group- size and body weight on these traits were tested. The assessments based on a scoring system comprising the scores 1 (very severely defective part of the body) to 4 (intact part of the body) were performed every three months during the laying period. Examinations of keel bone condition and measurements of body weight were performed in a total of 864 hens, claw length and plumage condition were examined in a total of 720 hens. Housing system showed a significant effect on the incidence of keel bone deformities and claw length. Plumage condition was significantly affected by group size, whereas plumage condition was worst in groups of 20 hens in Aviplus and in groups of 10 hens in Eurovent 625A-EU. Concerning claw length there were significant differences between diverse claw abrasives. The strongest abrasion was found in groups with two abrasive blocks, whereas perforated metal plates led to the least abrasion. Month of laying period showed a significant effect on each examined trait with a decrease in keel bone and plumage condition and an increase in claw length and body weight during the laying period.

Osteoporosis and bone fractures are a severe problem for the welfare of laying hens, with genetics and environment, such as housing system, each making substantial contributions to bone strength. In this work, we performed genetic analyses of bone strength, bone mineral density and bone composition, as well as body weight, in 860 commercial crossbred laying hens from two different companies, kept in either furnished cages or floor pens. We compared bone traits between housing systems and crossbreds, and performed a genome-wide association study of bone properties and body weight. As expected, the two housing systems produced a large difference in bone strength, with layers housed in floor pens having stronger bones. These differences were accompanied by differences in bone geometry, mineralisation and chemical composition. Genome-scans either combining or independently analysing the two housing systems revealed no genome-wide significant loci for bone breaking strength. We detected three loci for body weight that were shared between the housing systems on chromosomes 4, 6 and 27 (either genome-wide significant or suggestive when the housing systems were analysed individually) and these coincide with associations for bone length. In summary, we found substantial differences in bone strength, content and composition between hens kept in floor pens and furnished cages that could be attributed to greater physical activity in pen housing. We found little evidence for large-effect loci for bone strength in commercial crossbred hens, consistent with a highly polygenic architecture for bone strength in the production environment. The lack of consistent genetic associations between housing systems in combination with the differences in bone phenotypes support gene-by-environment interactions with housing system.
