The vaginal microbiota plays an important role in the health of dairy cattle, and it could be manipulated for prevention treatment reproduction-related infections. present study profiles compares healthy heifers during estrous cycle focusing results follicular (estrus) luteal (diestrus) phases using 16S rRNA sequencing V3–V4 hypervariable region. Twenty 13 to 16-month-old virgin from a single farm were included this study. Vaginal swabs blood samples obtained estrus (6-8 h before artificial...
Lactic acid bacteria (LAB) dominate human vaginal microbiota and inhibit pathogen proliferation. In other mammals, LAB do not microbiota, however shifts of dominant microorganisms occur during ovarian cycle. The study objectives were to characterize equine in mares by culture-dependent independent methods describe its variation estrus diestrus. Vaginal swabs from 8 healthy adult Arabian obtained For processing, isolated on Columbia blood agar (BA) Man Rogosa Sharpe (MRS) agar. comprised only...
Summary Studies have shown that ruminants constitute reservoirs of Listeria monocytogenes , but little is known about the epidemiology and genetic diversity this pathogen within farms. Here we conducted a large‐scale longitudinal study to monitor spp. in 19 dairy farms during three consecutive seasons ( N = 3251 samples). L . innocua was most prevalent species, followed by detected 52.6% more frequently cattle (4.1%) sheep (4.5%) than goat (0.2%). Lineage I accounted for 69% isolates. Among...
Sheep estrous synchronization is mainly based on progestagen-impregnated sponges which could cause vaginitis. Several species of Lactobacillus used as probiotics are commonly in the treatment or prevention urogenital infections humans. However, no studies have been performed to analyze potential use prevent sheep. A randomized controlled clinical trial was conducted with 21 one-year-old ewes develop a model probiotic infusion vaginal order study their influence ewe's microbiota, general...
Listeria monocytogenes is a foodborne bacterial pathogen responsible for listeriosis. Whole-genome sequencing has been extensively used in public health and food industries to characterize circulating isolates, but genomic data on isolates occurring natural environments wild animals are still scarce.
Our objective was to evaluate the correlated responses selection for litter size and its components after 10 generations of divergent uterine capacity (UC). A total 294 intact females from 11th 12th high low UC a cryopreserved control population used (139, 112, 43 females, respectively). Uterine assessed as in unilaterally ovariectomized females. Traits recorded on up five parities were (LS) number born alive (NBA). Laparoscopy performed all at d 12 their second parity, ovulation rate (OR)...
Changes in semen microbiota are associated with alterations to sperm quality and fertility. However, the from most livestock species has not yet been studied. Goats seasonal breeders, but never described this species, it is unknown how seasonality affects it. Our study objective 2-fold: describe goat buck ejaculates determine if differs between breeding non-breeding seasons. Semen six males of Murciano-Granadina breed was collected during both Two replicates were performed per male season on...
The aim of this work was to determine whether prenatal survival depends on the genotype mother or embryo and identify critical periods for mortality in two lines rabbits divergently selected by high (H) low (L) uterine capacity. Does from H (n = 124) L 115) were slaughtered at 72 h gestation. Embryos recovered gestation transferred oviducts recipient does 23) 19) lines. Each received eight embryos line into one oviduct other. Recipient d 28 No differences found between recovery either...

Selection based on phenotypic value rate, estimated at d 12 second gestation by laparoscopy. pressure approximately 30%. Line size 20 males and 80 females per generation. Traits recorded were rate gestation, laparoscopy as number corpora lutea in both ovaries; last postmortem; analyzed a single trait including gestation; right left rates; ovulatory difference, difference between litter size, total...

Cooling goat sperm insemination doses to 4 °C causes a delay in their delivery. However, chilling these during the transportation period could expedite delivery and process. In this study, an economical simple apparatus for semen itinere was developed, vitro quality vivo fertility of were compared with those chilled by means programmable water bath laboratory at rate −0.18 °C/min. Of tested prototypes, one that provided optimal combination (average −0.09 °C/min) time required reach (3 h 45...

The aim of this work was to study the effects genotype dam, embryo, or their interactions on prenatal growth by performing double-reciprocal embryo transfers between two lines rabbits divergently selected for uterine capacity.

This work evaluated the response to 10 generations of divergent selection for uterine capacity (UC) in rabbits determine whether this was symmetric by contrasting both lines against a cryopreserved control population. Animals came from 13th generation an experiment UC and The two were divergently selected generations, relaxed 11th until generation. Uterine estimated as litter size (LS) unilaterally ovariectomized (ULO) does. To create population, embryos base vitrified stored liquid N2...
The aim of this work was to evaluate the response in 10 generations selection for ovulation rate rabbits using a cryopreserved control population. Selection based on phenotypic value estimated at d 12 second gestation by laparoscopy. To produce population, embryos from 50 donor females and 18 males, belonging base generation line selected rate, were recovered. A total 467 (72-h embryos) vitrified stored liquid N(2) generations. size both populations approximately males females. number...
Fertility is one of the most economically important traits in farm animals, due to direct and indirect costs associated low pregnancy rates. Thus, priority goals animal reproduction predict performance that semen doses will have vivo based on quality values obtained laboratory assays. Attempts been made for getting a predictive model fertility frozen-thawed sperm dairy goats, but similar studies not conducted chilled goat buck are mostly used artificial insemination many countries including...
