Summary: The study revealed that the egg yolk-based semen extender performed better in cryopreserving semen from Merino rams. However, there were significant interactions between different semen extenders, semen processing, and collection months on sperm parameters. Further research is needed to address the causes of these interaction effects and improve semen extenders.

Summary: The study compared the effects of using gum arabic instead of egg yolk in the extender and supplementing with cysteine or ascorbic acid on semen quality and freezability in Noemi rams in vitro. Gum arabic extender supplemented with cysteine (0.5 or 1 mM) or ascorbic acid (0.5 mM) showed beneficial effects on semen quality after cryopreservation. The addition of antioxidants to both extenders had advantageous effects.

Summary: In a retrospective analysis of 508 ejaculates from 297 dogs, the efficiency of semen cryopreservation and the effects of age, season, and dog size on the characteristics of fresh and cryopreserved semen were evaluated. The study found that sperm cryotolerance is consistent for much of a dog's lifespan but decreases after a certain age. Dog semen can be cryopreserved successfully throughout the year and is not affected by dog body weight.

Summary: This study evaluated the effects of two commercial extenders on cooling llama semen, with the results showing that AndroMed (R) with egg-yolk addition had the highest total motility after 24 hours of cooling. Additionally, sperm membrane osmotic function was affected during cooling and there was an increase in the percentage of sperm with abnormal tails in samples cooled with Androstar (R) Plus.

Summary: This study examined the effects of supplementing bee bread extract (BBE) in extenders on the quality of cryopreserved ram semen. The results showed that the supplementation of BBE improved sperm motility, viability, and membrane integrity. BBE also promoted antioxidant and enzymatic activities and reduced apoptosis in semen during freezing.

Summary: This study investigates the viability of different diluents containing 6% Dimethylformamide (DMF) for preserving goose semen. The results suggest that Lactated Ringer's diluent with 6% DMF has the highest motility and vitality rates, making it a suitable choice for cryo-preservation of goose semen.

Summary: In Experiment 1, mature Angus bulls showed transient effects of ergot on post-thaw sperm motilities and velocities, while in Experiment 2, yearling bulls demonstrated age-related improvements in sperm characteristics, potentially masking any effects of ergot alkaloids. Overall, the study partially supported the hypothesis that ergot has no detectable adverse effects on post-thaw sperm quality in mature and yearling bulls.

Summary: The study suggests that nanowater can improve the quality of frozen-thawed ram semen, especially in glycerol-containing extenders. Different declustering times of nanowater can alter its properties, and it shows better cryoprotective effects in extenders with 7% glycerol.

Summary: The aim of this study was to evaluate the pregnancy outcomes and birth rates of alpaca females inseminated with frozen semen using two commercial extenders. The results showed that similar efficiency rates of pregnancy and alive offspring can be achieved through artificial insemination with frozen semen using Biladyl (R) B or AndroMed (R) diluents.

Summary: The high lipid content in porcine oocytes impairs in vitro embryo production, and this study evaluates the effects of lipid modulators on embryo development and lipid content. The results showed that DHA supplementation impaired oocyte maturation and embryo development rates, while PES did not favor porcine embryo development or reduce lipid content.

Summary: The effect of two acidifier blends on acidification potential, nutrient digestibility, blood metabolites, and daily gain of nursery piglets was evaluated. The results showed that the acidifiers did not improve the digestibility of nutrients in the diet, but the inclusion of AC2 acidifier had a negative quadratic effect on daily gain.

Summary: The aim of this study was to compare the reproductive performances of gilts and weaned sows grouped at different days after insemination. The study was conducted on a sow farm in Brazil using animals from the Camborough genetic line. The results showed that group housing gilts on different days after insemination did not affect reproductive performance, while sows mixed 2 days after insemination had a reduction in litter size compared to those mixed on day 1.

Summary: The aim of this case study was to assess the efficacy of fogging with a positive inoculum of M. hyopneumoniae to expose negative gilts in an acclimation program, and to evaluate the infection dynamics of M. hyopneumoniae in their piglets from lactation to slaughter. The use of fogging with a lung homogenate positive for M. hyopneumoniae successfully acclimated negative gilts. However, it did not prevent the presence of positive gilts at farrowing and the detection of the bacterium in their progeny by polymerase chain reaction.

Summary: Isoflurane, a commonly used inhalational anesthetic, has shown rapid anesthesia induction and quietness. However, little is known about its adverse effects on reproductive aspects. This study aimed to investigate the impact of acute isoflurane exposure on mouse sperm quality immediately before euthanasia and 20 days later. The results reveal that acute anesthetic exposure reduces sperm motility and leads to the formation of damaged sperm cells prone to apoptosis, potentially affecting reproductive experiment outcomes even after 20 days.

Summary: This study evaluated the effect of sperm concentration on boar semen quality and established concentration limits for their production. It was found that an increase in sperm concentration led to a linear decrease in sperm motility, while the integrity of plasma and acrosomal membranes and mitochondrial membrane potential were not significantly affected. Therefore, to maintain suitable sperm motility, the sperm concentration in boar semen doses should not exceed 55 x 10(6) cells/mL.

Summary: This study evaluated the metabolic profile in transition period Lacaune ewes according to parity and litter size born, and its influence on the transfer of passive immunity. The research found that ewes with higher litter sizes had a higher incidence of metabolic disorders, leading to production losses and potential health issues. Additionally, lambs born from these ewes had poorer immunity and lower live weights. It highlights the importance of monitoring the metabolic status and implementing measures to improve the health of ewes with higher litter sizes.

Summary: This study tested synchronization protocols without progestogens during the luteal phase in gilts. The results showed that the protocols based on PGF and hCG were effective in reducing the interval between estrus in gilts. Additionally, the hCG2 protocol had negative effects on the number of piglets born alive and total litter size.

Summary: Through monitoring 587 farrowings on Farm A and 929 on Farm B, it was found that high parity, prolonged farrowing, and a large litter size were the most significant risk factors associated with stillbirth in sows. On Farm B, farrowing intervention through vaginal palpation and oxytocin increased the odds of stillbirth. Additionally, low-birth-weight piglets were more likely to be stillborn compared to their medium and high-birth-weight counterparts.
