“…Grela and Walkiewicz ( 32 ) described a significantly lower feed intake when a diet with 20% of population rye (pre-fattening period) or 40% of rye (finishing period) was fed. In contrast, the use of 69% population rye compared to the use of a diet with 69% wheat had no negative influence on the feed intake of pigs from the 35th until 56th day of life ( 33 ). According to Weber et al ( 34 ), higher feed intakes were achieved when a diet with proportions of 15–30% population rye were fed to piglets (BW: 10–30 kg) compared to a diet based on wheat and barley.…”

Climate change and increasing demands to reduce the environmental impact of feed production are major challenges for animal nutritionists. Compared to wheat, which is commonly used in high levels in European piglet diets, rye is more efficient in using limited resources, most importantly, water and phosphorus. As a result, its cultivation has a relatively low carbon footprint. The high amounts of non-starch polysaccharides of rye might lead to an increased intestinal fermentation with potential beneficial effects on gut health. However, the high levels of non-starch polysaccharides in rye, which have a major impact on the physico-chemical conditions of the digesta, might affect digestibility and performance especially in young animals. It was therefore of interest to compare the effects of isoenergetic diets with increasing levels of rye as a replacement for wheat fed to young fattening pigs (bodyweight: 16–40 kg). The control diet contained 69% of wheat, while in the other three experimental diets, the amount of wheat was gradually replaced (by a third in each case) with rye. Thus, the experimental diets contained 23, 46, and 69% of rye. A total of 40 young pigs were housed individually in four dietary treatment groups. During a 4 week trial, effects on performance, digestibility, products of intestinal fermentation, and fecal characteristics were evaluated. There were no negative effects on feed intake and gains, even though the feed conversion ratio increased with the highest dietary rye level (69%). Digestibility rates of organic matter and crude protein did not differ significantly. Without affecting the characteristics of the feces, numerically higher amounts of intestinal fermentation products and higher colonic digesta mass were observed.

Alternatives to in-feed antibiotics in pigs: Evaluation of probiotics, zinc or organic acids as protective agents for the intestinal mucosa. A comparison of in vitro and in vivo results

-Weaned pigs are susceptible to frequent infectious diseases. Antibiotics have been used over decades to reduce pathogen infections, but many microorganisms are becoming resistant to antibiotics. Thus, there is an urgent need to find alternatives to in-feed antibiotics. Up to now, various compounds have been used as alternatives, giving promising but sometimes contrasting results. In recent years, the in vitro models of cell culture have been proposed for the screening of various compounds and understanding their mechanisms of action. The intestine is a complex system with a continuous cross-talk among epithelial cells, the local immune system and microflora. Alternatives to in-feed antibiotics may interact with any of these constituents. This review presents data on the protective effects of probiotics, zinc salts and organic acids, used as alternatives to in-feed antibiotics, against pathogen induced damage and inflammatory processes in the intestinal cells and the underlying mechanisms, with an attempt to compare in vitro and in vivo results. All the alternatives tested resulted in effective protection against pathogens by a series of interactions with intestinal cells and pathogens, including the inhibition of adhesion and invasion of pathogens, interference in signalling pathways induced by pathogenic bacteria, maintenance of the epithelial cell cytoskeleton and junctional structure and modulation of the host immune response. microorganismes sont devenus résistants à ces substances. Aussi, est-il urgent de trouver des alternatives aux antibiotiques additifs alimentaires. Jusqu'à présent, diverses alternatives ont été envisagées, certaines donnant des résultats prometteurs, d'autres des résultats variables. Au cours des dernières années, les modèles in vitro de cultures cellulaires ont été proposés pour cribler ces substances et élucider leurs mécanismes d'action. L'intestin est un système complexe faisant intervenir des communications permanentes entre les cellules épithéliales, le système immunitaire local et la microflore. Les alternatives aux antibiotiques peuvent interagir avec n'importe lequel de ces composants. Le présent article fait la synthèse des effets protecteurs et des mécanismes d'action des probiotiques, des sels de zinc et des acides organiques, utilisés comme alternatives aux antibiotiques dans les processus inflammatoires et les altérations cellulaires épithéliales in vitro, induites par des agents pathogènes. Elle tente de comparer ces résultats avec les observations in vivo. Toutes les alternatives évaluées ont été efficaces contre les agents pathogènes, via des mécanismes d'interaction cellules épithéliales-agents pathogènes. Ces mécanismes incluaient l'inhibition de l'adhésion et de l'invasion cellulaire par ces pathogènes, la modulation des mécanismes de signalisation intracellulaire induits par les bactéries pathogènes, le maintien de la structure du cytosquelette et des jonctions serrées des cellules épithéliales, et enfin la modulation des réponses immunitaires de la cellu...

Concentrations of amines were analysed in the digesta of piglets and fattening pigs after refining using an aminoacid-analyser. Feed contained only small amounts of putrescine. In the stomach histamine, tyramine, putrescine and cadaverine were nearly equally distributed, whereas in the colon cadaverine presented the main part. Piglets with 24% CP had in stomach/small intestine/hindgut 4.2/10.2/9.6 mmol, with 18% CP-/5.5/4.9 mmol amines/kg DM digesta. Fattering pigs showed in jejunal digesta from 2.1 to 8.7 mmol, in the caecum 1 to 4.8 mmol and in the colon 0.2 to 2.2 mmol amines/kg DM. Increasing CF-contents and bactericide supplements in the diet lowered amine concentration in all gut sections not significantly.
