A 2 x factorial experiment was carried out to evaluate the effect of herbage or concentrate feeding and dietary tannin supplementation on fatty acid metabolism composition in sheep ruminal fluid, plasma, intramuscular fat. Twenty-eight male lambs were divided into equal groups at 45 d age kept individual pens. One group given exclusively fresh (vetch), other fed a concentrate-based diet. Within each treatment, one-half received quebracho powder, providing 4.0% DM as tannins. Before...
We conducted an experiment to evaluate the effects that a diet containing condensed tannins with and without polyethylene glycol (PEG) has on lamb growth meat quality. Twenty-three male Comisana lambs were introduced three experimental diets between 45 50 d of age. Eight given 56% Ceratonia siliqua (carob) pulp (tannin group), another eight received same supplement 40 g PEG for each kilogram (PEG remaining seven conventional maize-based (maize group). Voluntary feed intake live weights...
This study evaluated the effects of tannins on ruminal biohydrogenation (BH) due to shifts in microbial environment sheep. Thirteen lambs (45 days age) were assigned two dietary treatments: seven fed a barley-based concentrate (control group) while other six received same with supplemental quebracho (9.57% dry matter). At 122 age, slaughtered, and contents subjected fatty acid analysis sampled quantify populations Butyrivibrio fibrisolvens, which converts C(18:2) c9-c12 (linoleic [LA])...
The aim of the present work was to study effects tannins from carob (CT; Ceratonia siliqua ), acacia leaves (AT; Acacia cyanophylla ) and quebracho (QT; Schinopsis lorentzii on ruminal biohydrogenation in vitro. extracted CT, AT QT were incubated for 12 h glass syringes cow buffered fluid (BRF) with hay or plus concentrate as a substrate. Within each feed, three concentrations used (0·0, 0·6 1·0 mg/ml BRF). branched-chain volatile fatty acids, acids microbial protein concentration reduced (...
Abstract Variations in diet, age and castration were employed to generate a range of flavours that chemically analysed find the cause ‘pastoral’ flavour sheepmeat its relationship species flavour. Lambs raised on pasture (ram or castrate) maize‐based lucerne‐based concentrate diet only). They slaughtered at 132 232 days. Fat from animals concentrates had lower proportions fat‐hardening stearic acid higher oxidation‐prone fat‐softening oleic linoleic acids. Concentrations...
A total of sixteen lambs were divided into two groups and fed different diets. Of these, eight a control diet (C) the C supplemented with quebracho tannins (C+T). The objective present study was to assess whether dietary can improve antioxidant capacity lamb liver plasma if such improvement is due direct transfer phenolic compounds or their metabolites, animal tissues. Feed, samples purified by solid-phase extraction (SPE) analysed liquid chromatography–MS for compounds. Profisitinidin...
The effect of animal feeding on milk volatile organic compounds (VOCs) metabolic origin was tested a hay-based diet (H), highly diversified pasture under continuous grazing (CG), or less rotational (RG). Individual 24 Montbéliarde cows (8 per treatment) were sampled after 2 weeks. Pasture-derived richer (p < 0.05) in camphene, sabinene, β-caryophyllene, and skatole than H milk. Neither yield nor fat content affected the majority VOCs measured. Skatole increased slightly with yield, while...
This study characterised the response of ruminal fermentation and rumen microbiome in lambs fed commercial vegetal sources hydrolysable tannins (HT) condensed (CT). Forty-four (19.56 ± 2.06 kg) were randomly assigned to either a concentrate diet (CON, n = 8) or CON supplemented with 4% two HT [chestnut (Castanea sativa, HT-c) tara (Caesalpinia spinosa, HT-t)] CT [mimosa (Acacia negra, CT-m) gambier (Uncaria gambir, CT-g)] extracts (all, 9) for 75 days pre-slaughter. Tannin supplementation...
Little information is available on the effects of different sources tannins ruminant product quality. Nowadays several tannin-rich extracts, produced from plants, are and contain belonging to chemical groups, but most these have not been used so far as feed supplements. The present study aimed at comparing feeding three tannin extracts (one containing condensed two hydrolysable tannins) lambs growth performances meat oxidative stability. Comisana male were divided into four groups (n=9 each)...
Carotenoid pigments are good biomarkers of grass feeding in sheep. However, grazing lambs often stall-finished because shortage. We investigated the nature carotenoids present sheep blood and their persistence this tissue. Four treatments were compared: 1) a concentrate-based diet (n = 10 lambs), 2) followed by long stall-finishing period 10), 3) short 4) to slaughter weight 10). The concentrate supply was regulated have similar average daily gain for all treatments. 40 allocated either or...
