Hematology and serum biochemistry values of free-ranging Iberian wolves (Canis lupus) trapped by leg-hold snares
Hematology and serum biochemistry are important tools in assessing the health and physiological status of wildlife populations. Nevertheless, studies on free-ranging wolves (Canis lupus) are scarce, and no reference values are available neither for Iberian wolves nor for wolves captured with leghold snares. We report 37 hematology and serum biochemistry variables obtained from 26 free-ranging Iberian wolves captured with leg-hold snares between 2007 and 2014, including variables previously not reported in the literature. The values obtained are similar to the published reference intervals for Scandinavian wolves captured by darting from a helicopter, except for higher values for mean corpuscular hemoglobin concentration (MCHC), red blood cell distribution width (RDW), leukocyte count, creatinine kinase (CK), ?-globulins, and total bilirubin (TBIL) and lower values for alkaline phosphatase (ALP). We propose that differences in leukocyte count, CK, and TBIL are related to the method of capture, while differences in RDW, MCHC, ALP, and ?-globulins could reflect physiological adaptations to environmental conditions, sampling, or pre-analytical artifacts. Lymphocyte count was lower and neutrophil/lymphocyte ratio was significantly higher in older, reproductive females, while ALP and phosphorus were higher in juvenile wolves. For the first time, we describe hematology and serum biochemistry values of free-ranging Iberian wolves captured with leg-hold snares. The data reported here is the first published reference for wolves captured with similar methods and for monitoring Iberian wolves populations’ physiological and health status.We thank Nuria Fandos and Carla Ferreira, rangers from Xunta de Galicia and Parque Nacional de los Picos de Europa, and volunteers who helped during the trapping sessions. The wolves were captured under projects financed by Associacao de Conservacao do Habitat do Lobo Iberico (ACHLI) in Portugal and by Picos de Europa National Park, Ministerio de Agricultura, Alimentacion y Medio Ambiente, and Xunta de Galicia in Spain.

Effect of endocervical inflammation on days to conception in dairy cows
In contrast to endometritis, now diagnosed by cytological examination, the effect of endocervical inflammation on reproductive performance has been inadequately investigated. In this study, endocervical and endometrial cytological specimens were collected from 168 Holstein cows between 21 and 60 days in milk (DIM) to investigate the prevalence of endocervical inflammation and effect on days to conception. Statistical analyses were stratified based on DIM at examination (= 35 DIM). Endocervical inflammation with >= 5% neutrophils before 35 DIM (disregarding the level of endometrial inflammation) was associated with decreased hazard of pregnancy within 300 DIM (adjusted hazard ratio, 0.4; 95% confidence interval: 0.3-0.8). A decrease in hazard of pregnancy was observed when >6% neutrophils were counted in endometrial smears (adjusted hazard ratio, 0.4; 95% confidence interval: 0.2-0.7). The study suggested an additive effect of combined endocervical and endometrial inflammation on the hazard of pregnancy within 300 DIM. Using the thresholds of 5% neutrophils for the cervix and 6% neutrophils for the uterus, 11% of the cows examined before 35 DIM presented cervicitis only, 13% were affected by endometritis only, and 32% suffered from both endometrial and endocervical inflammation. The presence (absence) of cervicitis was not indicative of the presence (absence) of endometritis. This study showed that in addition to uterine inflammation, endocervical inflammation in early lactation affects conception. Thus, the global evaluation of genital tract health may be more beneficial for reproductive performance than that of endometrial inflammation
