    A trial to assess the efficacy of eprinomectin (EPM) against the lungworm Dictyocaulus arnfieldi was carried out on 15, naturally-infected donkeys. Ten animals were treated with a 'pour-on' EPM preparation (at a dose of 0.5mg/kg bodyweight), and five animals acted as controls. EPM was 100% effective in eliminating faecal larvae from day 7, until the end of study at day 28. No adverse drug-reactions or side-effects were observed in any of the treated donkeys

    The aim of this study was to investigate the effect pre-partum habituation in the milkingparlour on behaviour and lactation performance of buffalo heifers. Sixteen buffalo heifersin late gestation were used for this study. The animals, with an age ranging from 30 to44 months at the start of the study, were equally allocated into two treatments and bal-anced for estimated calving date. Eight animals received pre-partum habituation for 10 daysbefore the estimated calving date (group H), while the eight others received no treatmentand served as the control (group C). During the pre-partum habituation sessions, group Hanimals were moved to the milking parlour and left for 10 min in the milking stall onceeach day, where the udder was thoroughly washed with warm water, wiped with a dis-posable towel and massaged. The behaviours, registered from entrance into the milkingstall to exit, were step and kick. After calving milk flow profiles, milk yield and milk qual-ity variables were determined along with behavioural recordings. The H animals duringthe habituation procedure showed a reduction in the number of steps (P < 0.001) and kicks(P < 0.01). After calving the H animals performed fewer steps than the control animals at 0(P < 0.001), 3 (P < 0.01), 6 (P < 0.01), 13 (P < 0.01) and 20 (P < 0.01) days after calving. Animalsfrom group H also performed fewer kicks than control animals at 0 (P < 0.001), 3 (P < 0.01),6 (P < 0.01) and 13 (P < 0.01) days after calving. In the C group a reduction in the numberof steps (P < 0.001) and kicks (P < 0.001) was observed as lactation proceeded, whereas forgroup H only a tendency for a reduction over lactation was detected. Pre-partum habitu-ation did not significantly affect milk quality or milk flow variables. Milk yield in the first3 min of milking (P < 0.001), and average milk flow (P < 0.001), increased throughout theexperimental period, whereas the duration of the pre-milking phase decreased as lactationproceeded (P < 0.001). This study shows that buffalo heifers exposed to a pre-partum habit-uation programme performed fewer steps and kicks than control animals during milking.Therefore, it is concluded that using this treatment can reduce the level of restlessness inbuffalo heifers during milking

    Mediterranean river buffalo oxytocin-neurophysin I (OXT) gene: structure, promoter analysis and allele detection

    Get PDF
    Oxytocin (OXT) is a very abundant nonapeptide neurohypophysial hormone implicated in several aspects of reproduction, including social, sexual and maternal behaviour, induction of labour and milk ejection. The nucleotide sequence of the whole OXTneurophysin I encoding gene (OXT) in Mediterranean river buffalo was determined, plus 993 nucleotides at the 5’ flanking region. Buffalo oxytocin gene sequence analysis showed two transitions in the promoter region (C→T in position – 966 and G→A in position – 790) and one transversion G→T at the 170th nucleotide of the second exon, responsible for the Arg97→Leu aa substitution which identifies an allele named OXT B. A PCR-RFLP based method for a rapid identification of carriers of these alleles has been developed

    Clinical Features, Cardiovascular Risk Profile, and Therapeutic Trajectories of Patients with Type 2 Diabetes Candidate for Oral Semaglutide Therapy in the Italian Specialist Care

    Introduction: This study aimed to address therapeutic inertia in the management of type 2 diabetes (T2D) by investigating the potential of early treatment with oral semaglutide. Methods: A cross-sectional survey was conducted between October 2021 and April 2022 among specialists treating individuals with T2D. A scientific committee designed a data collection form covering demographics, cardiovascular risk, glucose control metrics, ongoing therapies, and physician judgments on treatment appropriateness. Participants completed anonymous patient questionnaires reflecting routine clinical encounters. The preferred therapeutic regimen for each patient was also identified. Results: The analysis was conducted on 4449 patients initiating oral semaglutide. The population had a relatively short disease duration (42%  60% of patients, and more often than sitagliptin or empagliflozin. Conclusion: The study supports the potential of early implementation of oral semaglutide as a strategy to overcome therapeutic inertia and enhance T2D management

    Verifica del rapporto tra PKM e resa al caseificio nella valutazione della bufala da latte

    L’attitudine alla coagulazione del latte attualmente è stimata in base ad algoritmi che necessitano di essere rivisti ed aggiornati. La conoscenza delle interazioni tra management genoma e e resa casearia consentirà una valutazione sicuramente più precisa del merito dei soggetti. La caratterizzazione genetica attraverso l’applicazione delle tecniche di biologia molecolare (es. PCR, sequenziamento…) potrebbe fornire uno strumento valido per la selezione di animali che producano un latte con caratteristiche tecnologiche sempre più idonee a soddisfare le richieste del mercato, con ripercussioni positive sul miglioramento produttivo della specie ed, in ultima analisi, sull’economia dell’intero comparto. L’impiego della produzione embrionale in vitro a partire da oociti recuperati in vivo da donatrici selezionate consentirà di unire il vantaggio derivante dalla selezione effettuata per via paterna a quello che deriva dalla massimizzazione del contributo materno, permettendo di accelerare il processo selettivo attraverso la riduzione dell’intervallo generazionale

    Selection for buffalo milk quality and yield

    No full text
    The importance of buffaloes as a dairy species has been progressively increasing over the last years.The adoption of a selection programme is essential for the future development of breeds as it allows the enhancement of specific characteristics in accordance with the employed breeding system. Buffalo milk production selection criteria require several parameters to be considered at once. It is only this way that productive levels can be enhanced leaving milk characteristics unchanged. Hence the type trait of the species is maintained while at the same time being oriented towards those traits which are more suitable for breeding purposes. Present knowledge in buffalo doesn't allow the implementation of complex selection programmes. Research is currently ongoing and at least three study factors worth of special mention can be identified at this stage: milk production, milk quality, type traits, milkability
