Item type:Publication, Modification of the Standard 7-Day Ovsynch Protocol to Increase the Luteolytic and Synchronization Risks in Dairy Cows(Walter de Gruyter GmbH, 2020-10-01); ; ; ; Angjelovski, Branko<jats:title>Abstract</jats:title> <jats:p>We hypothesized that a single dose of PGF<jats:sub>2α</jats:sub> belatedly injected on day 8 after GnRH-1 in cows receiving a 7-day Ovsynch-56 protocol (GnRH – 7 days – PGF<jats:sub>2α</jats:sub> – 56h – GnRH – 16h – timed AI) will increase the proportion of cows with complete luteolysis. At day 35±3 postpartum, 70 lactating Holstein cows from one herd were scored for body condition and pre-synchronized with PGF<jats:sub>2α</jats:sub> and GnRH (3 days apart) and 7 days later submitted to an Ovsynch-56 protocol for first AI after random assignment to two treatments: (1) OV-7 (n=35) with an injection of PGF<jats:sub>2α</jats:sub> either on day 7; or (2) OV-8 (n=35) on day 8 after G1, respectively. Blood was collected before the first PGF<jats:sub>2α</jats:sub>, at day 7 and day 8 in OV-7 and OV-8, respectively, at AI and at 7 days after AI to assess progesterone concentration. Ten cows were classified as acyclic and were excluded from the analysis resulting in 60 cows (OV-8, n=27; OV-7, n=33). In total, more (P=0.01) OV-8 cows and more (P=0.04) primiparous OV-8 cows had complete luteolysis compared with their OV-7 herd mates. In addition, more (P=0.008) OV-8 cows with BCS<2.75 had complete luteolysis compared with their OV-7 herd mates, whereas no difference was observed between treatments among cows with BCS ≥2.75. In conclusion, delaying the application of PGF<jats:sub>2α</jats:sub> by 1 day reduced the percentage of primiparous cows and cows with poorer BCS having incomplete luteal regression at the time of AI.</jats:p> - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Prevalence and Clinical Signs of Postpartum Dysgalactia Syndrome at The First Day after Farrowing in Farmed Sows in The Republic of Macedonia(Walter de Gruyter GmbH, 2019-03-01); ; Bojkovski, Jovan<jats:title>Abstract</jats:title> <jats:p>The objective of the present study was to determine the prevalence of postpartum dysgalactia syndrome (PDS) and associated clinical signs in farmed sows in the Republic of Macedonia (RM) in the first 12-24 h postpartum. A total of 202 sows of different parity and different genetic lines from 5 pig farms in RM were included in the study. The sows and their litters were clinically examined 12-24 hours after farrowing. Postpartum dysgalactia syndrome was detected in 23.3% of all clinically examined sows, while prevalence between farms ranged from 14.8% to 38.1%. Altered piglet’s behavior was the most frequent clinical pattern observed in 68.1% of the PDS–affected (PDSA) sows. Regarding the clinical signs in PDSA sows detected among farms, significant differences were observed in the altered piglet’s behavior (p<0.05) and hypogalactia (p<0.05). Endometritis was more often detected in older sows (90%) compared to endometritis in younger animals (44.4%). In addition, fever was also more frequently diagnosed in higher parity (≥3 parity) sows (55.0%) in contrast to other PDSA sows (22.2%). This study has demonstrated the presence of PDS in farmed sows in RM. High frequency of altered piglet’s behavior found in this study could be an useful indicator for early detection of lactation problems in sows. Frequent pathological vaginal discharge in older sows indicates that endometritis plays an important role in the clinical manifestation of PDS. Further investigations should be conducted in order to identify specific risk factors associated with clinical PDS in farmed sows in RM.</jats:p> - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Brilliant Cresyl Blue Staining Enhances the Morphological Quality Evaluation of Porcine Oocytes-a Preliminary Study(Walter de Gruyter GmbH, 2023-06-07); ; Brilliant cresyl blue (BCB) staining is a method used for selection of developmentally competent porcine oocytes, in addition to the standard morphological classification. The aim of the current study was to assess the relationship between BCB staining in porcine oocytes with high and low morphological characteristics and its maturation rate. In the first part of the study, cumulus-oocytes complexes (COCs) (n=434) were aspirated from 60 ovaries. According to the morphological classification and BCB staining, they were divided in 4 groups: COC+/BCB+, COC-/BCB+, COC+/BCB-, and COC-/BCB-. In the second experiment, COCs (n=445) were categorized into 3 groups: control, BCB+, and BCB-. Significant differences in the maturation rate were observed between COC+/BCB+ and COC-/BCB- (66% vs. 23%), and between COC+/BCB+ and COC-/BCB+ (66% vs. 38%) (p<0.0001). Significant differences were also registered between COC-/BCB+ and COC-/BCB- (38% vs. 23%) and between COC+/BCB- and COC-/BCB- (53% vs. 23%) (p<0.01). Results from the second experiment showed that only BCB- oocytes had a significantly lower maturation rate (28%) compared to the control (63%) and BCB+ oocytes (59%) (p<0.001). These findings showed that COCs with high morphological characteristics had higher developmental ability compared to COCs with low morphology. The BCB-staining in high-quality oocytes did not have a significant impact on their maturation ability compared to a control group, but it might be useful for selecting developmentally competent oocytes with low morphology characteristics.
