Animal manure is one of the diffusion routes heavy metals and metalloids into environment, where soil can accumulate them. Heavy then be released groundwater sources, absorbed by crops, enter food chain with negative effects for human animal health. The aim this study was to evaluate concentration mineral nutrients from modern rearing systems in order develop effective strategies increase sustainability. Samples feed (n = 24: n 16 swine, 8 cattle), faeces 120: 80 40 cattle) water 8), were...

Antimicrobial resistance is a growing global concern, prompting for antibiotic alternatives in animal production. Seaweed, abundant bioactive compounds with anti-inflammatory properties, offers natural substitute to synthetic compounds. Considering this, the objective of present study was evaluate bioactivity three seaweeds 1:1 combination Ascophyllum nodosum, Palmaria palmata, and Ulva lactuca. Initially, polyphenol, flavonoid, total phlorotannin content seaweed species were assessed...

Butyrate and its derivatives may influence inflammatory status physiology in a variety of organisms organ systems. Inflammatory conditions the gastrointestinal tract, such as post-weaning diarrhea, negatively impact swine. Dietary intervention with butyrate-based compounds should be considered strategy to improve disease resistance pigs. We aimed assess properties different forms butyrate treatments using porcine cell culture experiments. This assessment inform future vivo feed experiments...

The effects of the dietary administration a combination Quebracho and Chestnut tannins, leonardite tributyrin were evaluated in weaned piglets. A total 168 piglets (Landrace × Large White) randomly allotted to two experimental groups (6 pens/group, 14 piglets/pen). Animals fed basal control diet (CTRL) treatment (MIX) supplemented with 0.75% tannin extracts, 0.25% 0.20% for 28 days. Individual body weight feed intake recorded weekly. Diarrhoea incidence was by faecal scoring scale (0-3;...

Abstract The loss of agrobiodiversity is a topic global impact. On local scale, Lombardy, in the Alpine macro-Region, has lost more than 78% its plant agrobiodiversity. Only four maize ( Zea mays L. subsp. ) landraces Lombardy are registered European Register Conservation Varieties. However, there other such as “Mais delle Fiorine”, which was characterized from an agronomic, morphometric, nutritional and genetic point view this research then compared with already (“Spinato di Gandino”,...
