Centro di Ricerca Avicoli

Il nostro Centro di Ricerca Avicoli, nella regione spagnola di Castiglia-La Mancia, ha una posizione unica, vicino alla capitale Madrid, e spazio sufficiente per ospitare più di 14.000 polli! La struttura comprende sette diverse tipologie di stalle dedicate all’allevamento di polli da carne e galline ovaiole. A causa della sempre maggiore importanza della trasparenza nella produzione di bestiame, tutte le strutture includono aree per i visitatori con protezione biologica per poter vedere le operazioni.

Impianto unico di alimentazione sperimentale in loco

Il Centro di Ricerca Avicoli dispone di un proprio impianto di alimentazione sperimentale, che ci consente di produrre tutto il mangime che utilizziamo in loco. Ciò consente di studiare un'elevata varietà di diete sperimentali e consente di risparmiare significative emissioni di CO2 equivalenti dai trasporti. Tutti i sacchi di mangime vengono pesati con precisione prima di essere trasferiti alla struttura e codificati a colori per differenziare i trattamenti.

Strutture per galline ovaiole

La struttura per le galline ovaiole può ospitare oltre 1.500 galline e ci consente di monitorare intensamente la salute e le prestazioni degli animali. Alcuni recinti sono appositamente progettati per studiare il concetto di split-feeding, in cui forniamo una composizione alimentare diversa alle galline ovaiole al mattino e alla sera, per soddisfare in modo più preciso le esigenze nutrizionali delle galline durante il ciclo di formazione delle uova. Questo è un ottimo esempio di nutrizione di precisione sostenibile, che porta a migliori prestazioni delle galline ovaiole e a ridotte emissioni di azoto e fosforo nell'ambiente. La struttura delle galline ovaiole ci consente di controllare completamente l'ambiente e simulare diverse circostanze in tutto il mondo. Possiamo studiare importanti parametri come l'assunzione di cibo e acqua, il peso corporeo e la composizione degli escrementi, nonché la qualità del guscio e delle uova.

L'incubatrice

L’incubatrice ci permette di monitorare i pulcini subito dopo la schiusa e di studiare gli effetti di genere, genetica, digiuno e disponibilità immediata di mangime. Questo studio fa parte del progetto LifeStart, basato sulla filosofia che ciò che accade durante i primi giorni di vita di un pulcino influisce sulle sue prestazioni nel corso della vita.

Strutture per polli da carne

Le strutture per i polli da carne possono ospitare oltre 6.000 uccelli, in una stalla dove il clima può essere completamente controllato. Uno degli studi eseguiti in queste strutture riguarda il nostro broiler model, che calcola i costi del mangime, i ricavi e il margine prevedendo crescita, FCR e resa della carcassa. Anche il nostro portafoglio di additivi per mangimi è stato ampiamente studiato in queste strutture.

La ricerca climaticamente controllata è ora possibile

L’ultima conquista del Centro di Ricerca Avicoli, costruita nel 2020, è una nuova struttura climatizzata con quattro sale di ricerca identiche che ci consentono di simulare condizioni ambientali contrastanti e valutare diverse soluzioni in scenari normali o più impegnativi.

L'opportunità per i visitatori, inclusi allevatori, accademici e altri ricercatori, di visitare la struttura e capire come la ricerca determina le nostre soluzioni porta un nuovo livello di trasparenza alle parti interessate lungo la catena alimentare.

Effect of L-glutamic acid N,N-diacetic acid on the availability of dietary zinc in broiler chickens

Poultry
Chelating agents can be used to improve the nutritional availability of trace minerals within the gastrointestinal tract. This study was conducted to determine the effect of a novel chelating agents, L-glutamic acid N,N-diacetic acid (GLDA), a biodegradable alternative to ethylenediaminetetraacetic acid on the nutritional bioavailability of zinc in broilers. Twelve dietary treatments were allocated to 96 pens in a randomized block design. Pens contained 10 Ross 308 male broilers in a factorial design with 6 incremental zinc levels (40, 45, 50, 60, 80, and 120 ppm of total Zn), with and without inclusion of GLDA (0 and 100 ppm) as respective factors. Experimental diets were supplied from day 7 to 21/22 and serum, liver and tibia Zn content were determined in 3 birds per pen. Growth performance and liver characteristics were not affected by dietary treatments, but both supplemental Zn and GLDA enhanced tibia and serum zinc concentration. The positive effect of GLDA was observed at all levels of the dietary Zn addition. The amount of zinc needed to reach 95% of the asymptotic Zn response was determined using nonlinear regression. When GLDA was included in the diet, based on tibia Zn, the same Zn status was achieved with a 19 ppm smaller Zn dose while based on serum Zn this was 27 ppm less Zn. Dietary GLDA reduces supplemental Zn needs to fulfill nutritional demands as defined by tibia Zn and serum Zn response. Considering the positive effect on the nutritional availability of Zn in broilers, GLDA presents an opportunity as biodegradable additive, to reduce Zn supplementation to livestock and thereby reducing Zn excretion into the environment, while fulfilling the nutrition Zn needs of farmed animals.

Efficacy of l-glutamic acid, N,N-diacetic acid to improve the dietary trace mineral bioavailability in broilers

Poultry
Trace minerals are commonly supplemented in the diets of farmed animals in levels exceeding biological requirements, resulting in extensive fecal excretion and environmental losses. Chelation of trace metal supplements with ethylenediaminetetraacetic acid (EDTA) can mitigate the effects of dietary antagonists by preserving the solubility of trace minerals. Lack of EDTA biodegradability, however, is of environmental concern. l-Glutamic acid, N,N-diacetic acid (GLDA) is a readily biodegradable chelating agent that could be used as a suitable alternative to EDTA. The latter was tested in sequential dose–response experiments in broiler chickens. Study 1 compared the effect of EDTA and GLDA in broilers on supplemental zinc availability at three levels of added zinc (5, 10, and 20 ppm) fed alone or in combination with molar amounts of GLDA or EDTA equivalent to chelate the added zinc, including negative (no supplemental zinc) and positive (80 ppm added zinc) control treatments. Study 2 quantified the effect of GLDA on the availability of native trace mineral feed content in a basal diet containing no supplemental minerals and supplemented with three levels of GLDA (54, 108, and 216 ppm). In study 1, serum and tibia Zn clearly responded to the increasing doses of dietary zinc with a significant response to the presence of EDTA and GLDA (P < 0.05). These results are also indicative of the equivalent nutritional properties between GLDA and EDTA. In study 2, zinc levels in serum and tibia were also increased with the addition of GLDA to a basal diet lacking supplemental trace minerals, where serum zinc levels were 60% higher at the 216 ppm inclusion level. Similar to the reported effects of EDTA, these studies demonstrate that dietary GLDA may have enhanced zinc solubility in the gastrointestinal tract and subsequently enhanced availability for absorption, resulting in improved nutritional zinc status in zinc-deficient diets. As such, GLDA can be an effective nutritional tool to reduce supplemental zinc levels in broiler diets, thereby maintaining health and performance while reducing the environmental footprint of food-producing animals.

Organic Acids as Alternatives for Antibiotic Growth Promoters Alter the Intestinal Structure and Microbiota and Improve the Growth Performance in Broilers

Poultry
The present study aimed to investigate the effects of organic acids (OA) as alternatives for antibiotic growth promoters (AGP) on growth performance, intestinal structure, as well as intestinal microbial composition and short-chain fatty acids (SCFAs) profiles in broilers. A total of 336 newly hatched male Arbor Acres broiler chicks were randomly allocated into 3 dietary treatments including the basal diet [negative control (NC)], the basal diet supplemented with 5 mg/kg flavomycin, and the basal diet supplemented with OA feed additives. Each treatment had eight replicates with 14 birds each. The results showed that AGP and OA promoted growth during day 22–42 compared with the NC group (P < 0.05). OA significantly increased the jejunal goblet cell density and ileal villus height on day 42 compared with the NC group (P < 0.05). Meanwhile, OA up-regulated the mRNA expression of jejunal barrier genes (Claudin-3 and ZO-1) relative to the NC group (P < 0.05). Significant changes of microbiota induced by the OA were also found on day 42 (P < 0.05). Several SCFAs-producing bacteria like Ruminococcaceae, Christensenellaceae, and Peptococcaceae affiliated to the order Clostridiales were identified as biomarkers of the OA group. Higher concentrations of SCFAs including formic acid and butyric acid were observed in the cecum of OA group (P < 0.05). Simultaneously, the abundance of family Ruminococcaceae showed highly positive correlations with the body weight and mRNA level of ZO-1 on day 42 (P < 0.05). However, AGP supplementation had the higher mRNA expression of Claudin-2, lower goblet cell density of jejunum, and decreased Firmicutes to Bacteroidetes ratio, suggesting that AGP might have a negative impact on intestinal immune and microbiota homeostasis. In conclusion, the OA improved growth performance, intestinal morphology and barrier function in broilers, which might be attributed to the changes of intestinal microbiota, particularly the enrichment of SCFAs-producing bacteria, providing a more homeostatic and healthy intestinal microecology.
