Q fever is a zoonotic disease that has been associated with reproductive problems in animals. As there little epidemiological data regarding the distribution and risk factors of this disorder cattle, objective study was to evaluate prevalence Coxiella burnetii among dairy herds northwest Spain, determine on-farm its effects on performance. Bulk tank milk (BTM) samples were collected from 262 commercial A Coruña, Lugo, Pontevedra provinces. Data about location, mean age, herd management...
This study examined the prevalence and risk factors of repeat breeder syndrome (RB) in 2370 dairy cows northern Spain. Data collected included postpartum pathologies, metabolic markers, productive reproductive parameters. The overall RB was 21.1%. In primiparous cows, body condition loss (Odds Ratio (OR): 2.9–8.1, depending on severity), ketosis (OR: 3.5), lameness 3.4), clinical mastitis 4.2), dystocia 5.2), endometritis 12.2) significantly increased risk. Summer 0.4) or autumn 0.6)...
In this paper, we describe links between skilling, the social, environmental, and didactic process by which farmers learn adapt knowledge; social reproduction, work of continually creating relations institutions political economy. Skilling is always contextual: ways that people on farms are shaped through ecological possibilities their space, economies in they do agricultural work, local networks inclusion exclusion, live. Social reproduction theory considers how class formed labor...
The aim of this study was to verify the importance postpartum serum levels certain metabolic markers as risk factors for subclinical endometritis (SE). Ninety-four Holstein cows were included in study, and examinations carried out between 30-45 days postpartum. Rectal palpation, vaginoscopy, transrectal ultrasound, endometrial cytology, blood sample collections performed. percentage polymorphonuclear neutrophils (%PMN) on endometrium evaluated, well glucose, cholesterol, triglyceride,...
Anogenital distance (AGD) is a marker of the degree prenatal exposure to androgens in multiple species, and it has been suggested that there an inverse association between AGD fertility. Therefore, aim this study was determine usefulness anti-Müllerian hormone (AMH) concentrations, indirect follicular population, as predictors future reproductive potential Holstein cattle. The measured 566 females from 9 dairy farms Galicia (Spain). A group 172 underwent second measurement months after....
The addition of 0.5% (v/v) Equex STM Paste (Nova Chemical Sales, Scituate Inc., MA, USA), whose active ingredient is sodium dodecyl sulphate (SDS), to a Tris-egg yolk extender was demonstrated improve the longevity frozen-thawed dog spermatozoa during in vitro incubation at 38 degrees C. aim first experiment compare effects two SDS-containing compounds, and Pasta (Minitüb, Tiefenbach, Germany), when added based extender, on post-thaw spermatozoa, as well intracellular Ca2+ concentration...
Contents This study was aimed to evaluate the reproductive performance of rabbit does artificially inseminated (AI) with a GnRH analogue [des‐Gly10, d ‐Ala6]‐LHRH. ethylamide induce ovulation by intravaginal administration, delivered in seminal dose. In preliminary experiment, 39 were divided into three groups (n = 13) that, at time AI, received following induction treatments: (i) control group: 20 μg gonadorelin administered intramuscularly; (ii) 25 added dose; (iii) 30 Fertility did not...
The objectives of this study were to determine: a) the agreement between postmortem endometrial cytology, uterine biopsy and presence intrauterine fluid in apparently normal genital tracts collected from culled dairy cows; b) results obtained paired horns using different diagnosis methods; c) microorganisms isolated uteri with cytological endometritis.One hundred grossly Holstein cows at a local slaughterhouse.Samples for histopathology bacteriology both horns, any content was determined...
Contents A 4‐year‐old Basque Shepherd male dog was presented for breeding soundness evaluation after the failed to impregnate three bitches he had mated. Clinical examination showed no anomaly of reproductive system. Semen normal sperm count (640 × 10 6 ), 80% progressively motile spermatozoa, and 96% morphologically abnormal which 84% proximal cytoplasmic droplet 12% plus other anomaly. zona pellucida‐binding assay, using canine oocytes derived from frozen‐thawed ovaries, performed in order...
Contents Studies performed on ejaculates from several species have identified discrete subpopulations of motile sperm. In dogs, sperm also been described in fresh and frozen‐thawed semen. The subpopulation the most rapid progressively has suggested to be likely source fertilizing spermatozoa. However, significance differences among dogs relative fertility is not known. aim this study was investigate relationship between proportion dog semen samples their ability bind zona pellucida canine...
The aim of this study was to evaluate the influence subclinical endometritis (SE) on reproductive performance dairy cows. Ninety-four cows parity 1 8, distributed in 25 herds, were examined once between 30 and 45 days milk using transrectal palpation, vaginoscopy ultrasonography. A cytological sample endometrium taken only from with an apparent healthy uterus (n=65). Serum glucose, total cholesterol, triglycerides, non-esterified fatty acids, β-hydroxybutyrate, proteins, albumin, urea...
The aim of the present study was to evaluate effect facility comfort level on animal-based welfare indicators as well productive and reproductive parameters 187 dairy farms in northwest Spain. Fifty-eight facility-based parameters, which included both housing facilities management were evaluated each farm used classify 5 groups (from 1: top 5: worst farms). Animal-based compared among groups. Lameness score significantly differed (p < .005) (67% cows having normal gait) versus 4 (55%) (53%)....
One of the main drawbacks using endometrial cytology in cows is time required for sample collection and interpretation. It recommended to count a large number polymorphonuclear neutrophils (PMN) calculate their overall percentage. However, since counting cells laborious method, it would be preferable simplify analysis by PMN few microscopic fields. Therefore, aim this study was assess whether simple test, based on calculating average 10 fields at 1000×, could reliable technique diagnosis...
We have previously reported that alpaca oocytes require between 38 and 42 h of maturation time (Huanca et al. 2010 Reprod. Fertil Dev. 22(1), 327). The objective this study was to evaluate the effect addition FSH in medium on nuclear cleavage rate. Ovaries were collected from a slaughterhouse transported laboratory thermos flask containing saline solution 0.9% with antibiotic antimycotic at 35°C. Cumulus–oocyte complexes (COC) obtained by slicing ovaries scalpel pooled conical tube for...
