The major histocompatibility complex (MHC) contains genes important for immune response in mammals, and these genes exhibit high polymorphism and diversity. The DRA gene, a member of the MHC class II family, is highly conserved across a large number of mammalian species, but it displays exceptionally rich sequence variations in Equidae members. We analyzed allelic polymorphism of the DRA locus in 248 donkeys sampled across the Balkan Peninsula (Albania, Bulgaria, Croatia, Macedonia, Greece and Montenegro). Five known alleles and two new alleles were identified. The new allele Eqas-DRA*0601 was found to carry a synonymous mutation, and new allele Eqas-DRA*0701, a non-synonymous mutation. We further analyzed the historical selection and allele genealogy at the DRA locus in equids. Signals of positive selection obtained by various tests were ambiguous. A conservative conclusion is that DRA polymorphism occurred relatively recently and that positive selection has been acting on the DRA locus for a relatively brief period.

The objectives of the present study were to determine the production performances of sows on commercial pig farms in the Republic of Macedonia, to compare the differences in sow productivity data between small and large farms and to examine interrelationships of key production parameters among farms with different sizes. The study was retrospectively based and included the annual (2012) analyses of the sow productivity data in small (<200 sows, n=4) and large (200-1000 sows, n=5) commercial pig farms. The data was statistically evaluated and compared with the known literature. Sows productivity was greater on the small farms compared to the large ones. The small farms had larger litter per sow (PBL), more pigs born alive (PBA), higher weaning weight (WW) and more pigs weaned per sow per litter (PWSL) than the large ones (p<0.001). Small farms also had greater farrowing rate (FR) (p<0.01). Higher replacement rate (RR), lower average parity (AP), greater number of litters per sow per year (LSY) and higher sow death rate (SDR) were observed in large farms (p<0.001). The large farms also had less non-productive days (NPD) than the small farms (p<0.001). Different intensity of correlations also were observed for several productive parameters among the farm groups. The data obtained in this study show that sow productivity on Macedonian pig farms is lower than in EU countries. Small herds are more efficient than the large herds. Despite all limitations, our study provides information for veterinarians regarding reproductive parameters of sows and their interrelationships on Macedonian pig farms. Further investigation should be made in order to identify whether specific management factors have effect on the productivity of the breeding herd.</jats:p>

<jats:title>Abstract</jats:title> <jats:p>The objectives of the present study were to examine the fatty acid (FA) profiles in serum and in the follicular fluid (FF) and the association between polyunsaturated fatty acid level (PUFA) and follicular growth dynamics following induced luteolysis in dairy cows. A total of 29 dairy cows (CL>25mm, follicle≈15mm) at d0 (start of the experiment) were submitted to ultrasound guided transvaginal follicular aspiration for FF collection from the largest follicle and were injected with 500 μg of cloprostenol. The cows were subdivided into Group A1 (n=11) and Group A2 (n=8) resuming follicular growth either from a secondary follicle less than or larger than 8.5mm, respectively, present at the moment of aspiration and Group A0 (n=10) not resuming follicular growth. Follicular development was monitored daily by ultrasonography until the next dominant follicle reached ≈15mm and was subsequently punctured in Group A1 and A2 (d1). Serum and FF samples for FA determination were taken at d0 from all cows and at d1 in Group A1 and A2. No differences were observed between the FA profile in serum nor in FF between sampling days. Regarding the PUFA levels, the serum linoleic acid (C18:2n6) levels at d0 and d1 were significantly higher than in FF, while alpha linolenic acid (C18:3n3) was lower in the serum than in FF, both at d0 and d1. At d0, a tendency for negative correlation between serum and the FF C18:2n6 with subsequent daily follicular growth rate was observed, while, at d1 there was a strong negative correlation between the serum C18:2n6 and daily growth rate (r=−0.71; p=0.0006). The present study revealed similarities of the FA profiles in the serum and in the FF and association between serum and FF PUFA content with the follicular dynamics after induced luteolysis.</jats:p>

The objective of this study was to gather information about the prevalence of bacterial species in farmed sows, with special focus on the clinical manifestation of postpartum dysgalactia syndrome (PDS). One hundred and sixteen sows from 5 pig farms in the Republic of Macedonia were clinically examined for PDS 12–24 h after farrowing. Milk samples and vaginal swabs for bacteriological testing were taken from PDS-affected (PDSA, n = 30) and PDS-unaffected (PDSU, n = 86) sows. Escherichia coli, staphylococci, and streptococci were the predominant bacteria isolates. Escherichia coli was the most frequently found isolate, with a prevalence of 73.3% in PDSA and 31.4% in PDSU sows. Compared to PDSU sows, Escherichia coli was more prevalent in both milk (53.8% vs. 31.4%) and vaginal swabs (74.3% vs. 47.1%) from PDSA sows. Greater prevalence of Escherichia coli in vaginal swabs (66.7%) from PDSA sows suggests that the genital tract represents a possible route for transmission of the infection and that Escherichia coli plays a major role in the development of clinical PDS. Further investigation should be made in order to identify whether specific virulent factors of this bacterium isolated from the genital tract of PDSA sows are associated with clinical occurrence of the syndrome.

<jats:title>Abstract</jats:title> <jats:p> The aim of this study is to compare the results from the histopathology and the immunohistochemical method in the diagnostic of Porcine circovirus type 2 (PCV2) infection in pigs. The circovirus infection is a pig disease that is caused by a small, spherical, nonenveloped virus with a single stranded DNA genome which is spread throughout the pig industry worldwide. The circovirus is the etiological agent of a several pig diseases which today are thought to be the cause of the greatest economical loses in pig production. The most important of these diseases is the PMWS (post-weaning multisystemic wasting syndrome). In this article we have performed an investigation of four farms on which there had been a previous clinical diagnosis of the Post-weaning multisystemic wasting syndrome. The examination was performed on thirty pigs from these farms, from two to five months old, which had the most severe symptoms of the disease. Necropsy, histopathology and immunohistochemical diagnostic methods were performed. The most significant necropsy findings were the enlarged lymph nodes (especially the inguinal, mediasinal and the mesenteric lymph nodes). The main histopathological changes were located in the lymphatic organs presented by B and T lymphocyte depletion and increase in the number of the macrophages. PCV2 antigen and nucleic acid were detected in almost all of the examined tissues. The examination showed that the histopathological and immunohistochemical methods provide complementary results in diagnosing PCV2 in pigs.</jats:p>

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>
