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])...
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)...
This work investigated the effects of feeding whole pomegranate byproduct (WPB) to lambs on ruminal, liver, and intramuscular fatty acids (FA). Seventeen lambs, divided into two groups, were fed for 36 days with a cereal-based concentrate diet (CON) or containing 200 g/kg DM WPB partially replace barley corn (WPB). The dietary treatment did not affect final body carcass weight, dry matter intake, average daily gain. However, total polyunsaturated FA (PUFA), linolenic, rumenic (RA), vaccenic...
The goal of the trial was testing effects a blend organic acids and essential oils dietary supplementation on growth performance gut healthiness in broiler chickens. In total, 420 male Ross 308 chicks (1-day old) were randomly assigned to two treatments: basal (BD) (OA&EO) diets (three replicates/treatment; 70 broilers/replicate). BD group received commercial whereas OA&EO + 5 g/kg microencapsulated oils. treatment improved average daily gain (p < 0.01) feed conversion ratio at...
This study aimed to investigate the effect of dietary hazelnut skin (HNS), a by-product confectionery industry, on oxidative stability lamb meat. Twenty-two finishing lambs were randomly assigned 2 groups and fed ad libitum for 56 days different concentrate-based diets: one control experimental, in which 150 g/kg corn was replaced by HNS. After slaughter, fat-soluble vitamins content hydrophilic antioxidant capacity assessed fresh meat, as well color, lipid protein over 7 shelf-life trial....
The high degradability of crude protein (CP) from fresh grass can impair its utilization in ruminants. presence a moderate level polyphenolic substances the diet grazing animals could help to overcome this problem. study aimed evaluate effects supplementation with two varieties faba bean, different polyphenol contents, on milk yield and quality, as well behaviour, Cinisara cows. A total 30 cows, homogeneous per days (61 ± 29) (12.9 kg 3.2), fed mixed pasture (CP 17.9% DM) supplied grains (an...
The aim of the present study was to evaluate effect inclusion stoned olive cake and rolled linseed in a concentrate-based diet for lambs on fatty-acid composition polar non-polar intramuscular lipids longissimus dorsi muscle. To achieve this objective, 32 Appenninica were randomly distributed into four groups eight each fed conventional cereal-based concentrates (diet C); containing 20% dry matter (DM) basis L); 35% DM OC); both (10% DM) (17% DM; OCL). administered together with grass hay at...
The aim of this study was to investigate the effect dietary whole dried citrus pulp (DCP) on antioxidant status lamb tissues. In total, 17 lambs were divided into two groups and fed for 56 days: a barley-based concentrate diet (CON - eight animals), or concentrate-based including 35% DCP partially replace barley (CIT nine animals). CIT contained double concentration phenolic compounds than CON (7.9 v. 4.0 g/kg dry matter (DM), respectively), but had no (P>0.05) overall capacity hydrophilic...
