Centro di Ricerca Suini

Il Centro di Ricerca Suini, che comprende stalle per suinetti, scrofe e magronaggio-ingrasso, si trova vicino a Boxmeer, nei Paesi Bassi. In loco possono essere ospitati più di 1.500 suini.

Strumenti ad alta tecnologia per un monitoraggio ravvicinato

Il Centro di Ricerca Suini è dotato di stazioni di alimentazione e abbeveraggio elettroniche, per consentirci di monitorare individualmente l'assunzione di cibo e acqua e studiare i modelli di assunzione. Questo monitoraggio può rivelare spunti interessanti, come il fatto che nessuna scrofa è uguale per quanto riguarda il consumo di acqua; l'assunzione giornaliera di acqua può essere molto diversa da una scrofa all'altra. I modelli di assunzione di mangime rivelano anche molto sul "programma giornaliero" naturale degli animali; come gli umani, fanno colazione, pranzo e cena ogni giorno.

Tutti i recinti includono materiali di arricchimento che migliorano il benessere degli animali; ad esempio, l'unità di gestazione è dotata di scrubber posteriori (originariamente progettati per i bovini) perché molte scrofe godano di una buona sessione di lavaggio. Forniamo anche palline sospese con cui giocare. Tutte le stanze sono dotate di sorveglianza video e audio continua che ci consente di studiare da vicino il comportamento degli animali o, quando viene rilevato un problema, “riavvolgere il nastro” per capire cosa sia successo.

Inaugurazione virtuale dell'unità dedicata alla nutrizione e alla salute dei suini

La più recente novità delle strutture di ricerca Trouw Nutrition è l’inaugurazione dell'unità dedicata alla nutrizione e alla salute dei suini. Costruita nel 2020, si compone di quattro stanze identiche che sono sia sanitarie che climatiche e rendono possibile il monitoraggio individuale del consumo di mangime e acqua. La caratteristica fondamentale della nuova unità è che ci consente di simulare qualsiasi condizione da tutto il mondo. Per garantire che le stanze possano mantenere zone climatiche indipendenti, ognuna di esse è dotata di un proprio sistema di ventilazione. Ciò impedisce anche la contaminazione incrociata e riduce le emissioni e gli odori. Nel 2021 abbiamo iniziato l'anno con un taglio del nastro virtuale per inaugurare questa nuova struttura!

The role of lactose in weanling pig nutrition: a literature and meta-analysis review

Swine
Lactose plays a crucial role in the growth performance of pigs at weaning because it is a palatable and easily digestible energy source that eases the transition from milk to solid feed. However, the digestibility of lactose declines after weaning due to a reduction in endogenous lactase activity in piglets. As a result, some lactose may be fermented in the gastrointestinal tract of pigs. Fermentation of lactose by intestinal microbiota yields lactic acid and volatile fatty acids, which may positively regulate the intestinal environment and microbiome, resulting in improved gastrointestinal health of weanling pigs. We hypothesize that the prebiotic effect of lactose may play a larger role in weanling pig nutrition as the global feed industry strives to reduce antibiotic usage and pharmacological levels of zinc oxide and supra-nutritional levels of copper. Evidence presented in this review indicates that high dietary lactose improves growth performance of piglets, as well as the growth of beneficial bacteria, particularly Lactobacillus, with the positive effects being more pronounced in the first 2 weeks after weaning. However, the risk of post-weaning diarrhea may increase as pigs get older due to reduced lactase activity, high dietary lactose concentrations, and larger feed intakes, all of which may lead to excessive lactose fermentation in the intestine of the pig. Therefore, dietary lactose levels exert different effects on growth performance and gastrointestinal physiological functions in different feeding phases of weanling pigs. However, no formal recommendation of lactose for weanling pigs has been reported. A meta-analysis approach was used to determine that diets fed to swine should include 20%, 15%, and 0 lactose from d 0–7, d 7–14, and d 14–35 post-weaning, respectively. However, sustainable swine production demands that economics must also be taken into account as lactose and lactose containing ingredients are expensive. Therefore, alternatives to lactose, so called “lactose equivalents” have also been studied in an effort to decrease feed cost while maintaining piglet performance with lower dietary lactose inclusions. In summary, the present review investigated dose-response effects of dietary lactose supplementation to exert positive responses and begin to elucidate its mechanisms of action in post-weaning pig diets. The results may help to replace some or all lactose in the diet of weanling pigs, while improving production economics given the high cost of lactose and availability in some swine production markets.

Fibre supplementation to pre-weaning piglet diets did not improve the resilience towards a post-weaning enterotoxigenic E. coli challenge

Swine
Dietary fibre (DF) is implicated in gastrointestinal health of weaned piglets, either through its physiochemical properties, through modulation of gut microbiota and (or) improved gut integrity. We aimed to study the effect of DF enriched supplemental diets fed to suckling piglets ('creep feed') on health and performance after weaning when challenged with an enterotoxigenic E. coli (ETEC). Seventy-two piglets originating from 28 litters had been fed four creep diets, that is a low-fibre control (CON); a diet containing 2% long-chain arabinoxylans from wheat (lc-AXOS) or 5% purified cellulose (CELL) or a diet containing the high fermentable and the low-fermentable fibre source (i.e. 2% lc-AXOS and 5% CELL). Upon weaning, piglets were individually housed and all fed the same diet. On days 7, 8 and 9, animals received an oral dose of ETEC (5 ml containing 107 to 108 CFU/ml). Besides growth performance, faecal and skin scores were recorded daily. Gut permeability was assessed by urinary excretion of Co-EDTA prior and post-ETEC challenge. Repeated measures in time were statistically evaluated with generalized linear mixed models. We used a binominal distribution for evaluating the faecal and skin scores. Feed intake and body weight gain did not differ between treatments (p > .05). Piglets on CELL decreased gain:feed ratio in week 2 + 3 week compared to CON (p = .035). Prior to ETEC challenge, gut permeability tended to increase for lc-AXOS (p = .092). Moreover, lc-AXOS as main effect increased intestinal permeability before ETEC challenge (p = .013), whereas the low-fermentable fibre lead to elevated intestinal permeability after ETEC challenge (p = .014). The incidence of diarrhoea was higher for lc-AXOS + CELL compared with lc-AXOS (p = .036), while skin condition was unaffected. In conclusion, neither the high fermentable nor the low-fermentable fibre source improved post-weaning growth or gastrointestinal health of the piglets.

Impact of Yeast-Derived β-Glucans on the Porcine Gut Microbiota and Immune System in Early Life

Swine
Piglets are susceptible to infections in early life and around weaning due to rapid environmental and dietary changes. A compelling target to improve pig health in early life is diet, as it constitutes a pivotal determinant of gut microbial colonization and maturation of the host’s immune system. In the present study, we investigated how supplementation of yeast-derived β-glucans affects the gut microbiota and immune function pre- and post-weaning, and how these complex systems develop over time. From day two after birth until two weeks after weaning, piglets received yeast-derived β-glucans or a control treatment orally and were subsequently vaccinated against Salmonella Typhimurium. Faeces, digesta, blood, and tissue samples were collected to study gut microbiota composition and immune function. Overall, yeast-derived β-glucans did not affect the vaccination response, and only modest effects on faecal microbiota composition and immune parameters were observed, primarily before weaning. This study demonstrates that the pre-weaning period offers a ‘window of opportunity’ to alter the gut microbiota and immune system through diet. However, the observed changes were modest, and any long-lasting effects of yeast-derived β-glucans remain to be elucidated.
