In 2016, two little penguins/kororā (<i>Eudyptula minor</i>) showed respiratory disease on admission to the zoo hospital. Post-mortem samples of liver and lung were collected from the penguins and from 10 other birds from the zoo's collection that died without clinical signs. Further, 128 conjunctival, choanal and cloacal swabs were collected from 27 different bird species, all housed within the zoo and without clinical signs.In 2019, a cluster of deaths of four diamond doves (<i>Geopelia cuneata</i>) and two superb parrots (<i>Polytelis swainsonii</i>) occurred in one mixed-species aviary. Twenty post-mortem samples were collected from these birds and other birds that died around the same time across the zoo.

Sera were tested with an ELISA for antibodies to <i>N. caninum</i>, with the thresholds increased (based on unpublished data) to account for colostrum intake. The sample/positive (S/P) cut-off value for seronegative animals was increased from the manufacturer's recommendation of S/P < 30 to < 70; the S/P value for seropositive was increased from ≥ 40 to ≥ 100; and S/P values 70-100 were considered inconclusive. Calves with inconclusive results were retested using standard thresholds at approximately 4 months of age (after colostral antibodies had waned). Seropositive calves were removed from the replacement herd. This protocol was first implemented in 2016. From 2018 onwards, parentage testing was carried out, and the calves' results were extrapolated to their dams. Dams of seropositive calves were bred predominantly to beef semen. The proportion of seronegative calves in each cohort from 2016 to 2023 was calculated, and the reproductive performance of seronegative replacement calves (% producing a calf at approximately 24 months of age) was analysed.<b>Results:</b> The proportion of seropositive replacement calves peaked in 2017 (19.5%) and by 2023 had reduced to 1.2%. The odds of a heifer being seronegative in 2023 compared to 2016 were 14.0 (95% CI = 4.12-87.56) times higher. Compared to 2014/2015 when replacement heifers' serostatus was unknown, after 2016 (the first year when replacement heifer serostatus was established) at least 12.9% more heifers produced a calf at approximately 24 months of age; compared to 2014 the odds were at least 2.88 (95% CI = 1.75-4.88) times higher.<b>Conclusions and clinical relevance:</b> Combining early testing of replacement heifers with the identification and breeding management of dams of seropositive replacement heifers reduced the proportion of seropositive heifer calves in subsequent years and improved the reproductive performance of heifer cohorts. Further research is required to establish optimal ELISA cut-off values, but this strategy is likely to be a useful tool to reduce the <i>N. caninum</i> seroprevalence in endemically infected dairy herds.<b>Abbreviations:</b> BVDV: Bovine viral diarrhoea virus; S/P: Sample/positive ratio.</p>","PeriodicalId":19322,"journal":{"name":"New Zealand veterinary journal","volume":" ","pages":"328-336"},"PeriodicalIF":1.1,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144226085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The binding forces of host-guest components are generally weak bonds like electrostatic interactions, van der Waals force, and hydrogen bonds.

Its nutritional qualities, that include high content of ascorbic acid (AsA), tocopherols and other antioxidants, make it attractive for consumers. Fruit size is an important issue for consumers and producers, because it defines the fruit price. The aim of this work was to evaluate the postharvest life of two different kiwi fruit sizes, small and large fruits, combined with the treatment of an ethylene signal inhibitor, 1-methylcyclopropene (1-MCP), under storage at 3 ºC for up to six months. Large fruits showed an earlier respiration peak (two months) than small fruits. After four months from harvest, the amount of AsA in small fruits was higher than that of large fruits, independently from the 1-MCP treatment. On the other side, the application of 1-MCP delayed the loss of firmness in small and large fruits but did not affect quality parameters such as soluble solids or total titratable acidity. Small kiwifruits showed a greater weight loss while large fruits showed a decrease in the total sugars when they were treated with 1-MCP. Small fruits increased the AsA and malic acid content, presenting nutritional attributes that could improve the consumers' diet.
