| 1 | Metabolomics characterization of colostrum in three sow breeds and its influences on piglets' survival and litter growth rates显示文摘Background: Colostrum is the first secretion produced by mammary glands during the hours immediately preceding and succeeding parturition. This secretion differs from milk and represents an essential vehicle of passive immunity,prebiotic compounds and growth factors involved in intestinal development. Most of the literature concerning colostrum composition refers mainly to human and cow; and little is known about pig colostrum metabolome and how it varies between pig breeds and different farrowing parity. Thus, the aim of the present research is to provide new information about pig colostrum composition and the associations between metabolites, the sows' breed and the survival and growth rates of their litters.Results: Colostrum samples were gathered from 58 parturitions of sows belonging to three different breeds chosen for their importance in Italian heavy pig production: 31 Large White, 15 Landrace and 12 Duroc respectively. The defatted and ultrafiltered colostrum samples were analysed using1 H–NMR spectroscopy. Principal Components Analysis(PCA) was assessed on the obtained spectra. In addition, using a Stepwise Regression and a Linear Regression analyses the metabolites named after the signals assignment were tested for their associations with piglets' performances.Twenty-five metabolites were identified, comprehending monosaccharides, disaccharides(such as lactose), organic acids(lactate, citrate, acetate and formate), nitrogenous organic acids(such as creatine) and other compounds,including nucleotides. PCA results evidence a clustering due to breed and season effects. Lactose was the main compound determining the assignment of the samples into different clusters according to the sow breed. Furthermore, some metabolites showed to be associated with piglets' performance and survival traits: acetate and taurine were positively related to litter weight gain and piglets' survival rate, respectively, while dimethylamine and cis-aconitate were linked to new-borns' impaired ability to survive.Conclusions: The results obtained suggest that colostrum composition is affected by breed, which, together with environmental conditions, may cause changes in colostrum metabolites content with possible consequences on piglets' performances. Among the identified metabolites, acetate, taurine, dimethylamine and cis-aconitate showed consistent associations with piglets' survival rate and litter weight gain, implying that these compounds may affect new-borns' ability to survive. | Gianfranco Picone Martina Zappaterra Diana Luise Alessia Trimigno Francesco Capozzi Vincenzo Motta Roberta Davoli Leonardo Nanni Costa Paolo Bosi Paolo Trevisi | 2018 | Journal of Animal Science and Biotechnology2018，9，3： | 6 |
