Extensive ruminant farming systems often face fluctuating pasture availability, resulting in two periods with very different forage quality. Tannins are natural bioactive compounds able to modify ruminants' digestive metabolism thanks their properties. To evaluate a differential effect of tannins feeding situations, according the availability along year, an vitro rumen incubation trial was performed. Buffered sheep content incubated substrates, vetch (VP) and hay (VH), presence tannin...
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....
This study investigated the effect of two supplementation levels zinc glycinate (ZnGly) on performance, carcass characteristics, and meat quality growing-finishing pigs. Thirty pigs (bodyweight: 61 ± 4.0 kg) were assigned to three treatments fed ad libitum for 56 days a diet supplemented with 0 (control), 45 (Zn45), or 100 mg/kg (Zn100) ZnGly. The highest ZnGly lowered average daily gain (P = 0.031); while, cold weight did not differ between treatments. Both reduced chill loss < 0.001)....
The aim of the present study was to assess dietary supplementation tannins grazing dairy cows in 2 seasons characterized by a good quality pasture (spring) or poor-quality (summer). effects were assessed on plasma antioxidant status and cytokines profile properties cheese vitro digestates. Fourteen lactating divided into homogeneous groups (n = 7): control group (CON), an experimental (TAN) receiving 150 g/head per day supplementation. experiment performed twice, spring summer. animals free...
Two groups of ten barrows received a conventional- (CTRL) or an experimental- (HZL) finishing diet containing 11% hazelnut skin. From each barrow, two types salami (namely, NITR, and PHEN) were obtained. NITR was added with E250 E252. The latter replaced by phenolic concentrated extract from olive-milling wastewaters in PHEN salami. Salami fatty acids (FA), antioxidant capacity, lipid color stability during refrigerated storage assessed. A consumer test also performed. Feeding strategy...
This study aimed to assess the effect of dietary tara (Tara spinosa (Feuillée ex Molina) Britton & Rose) hydrolysable tannins on performance and meat quality finishing pigs. Twenty barrows (crossbred PIC × Piétrain; age: 125 ± 5 d; bodyweight: 60.8 3.89 kg) were randomly assigned two groups fed ad libitum for 7 weeks a control diet (CON) or supplemented with 10 g/kg (TAT), respectively. No differences (P > 0.10) growth carcass traits observed between groups. Meat fatty acid profile was not...
Abstract Extensive farming systems are characterized by seasons with different diet quality along the year, as pasture availability is strictly depending on climatic conditions. A number of problems for cattle may occur in each season. Tannins natural polyphenolic compounds that can be integrated cows’ to overcome these seasonal problems, but little known about their effect milk according This study was designed assess effects 150 g/head × day tannin extract supplementation proximate...
Abstract Background Magnolia bark extract (MBE) is a natural supplement with antioxidant, anti-inflammatory, and antimicrobial activities. Its properties suggest that the dietary supplementation in livestock could improve quality of products. Therefore, aim this study was to investigate, for first time, effect MBE (0.33 mg/kg) finishing pigs on oxidative stability meat. Oxidative paramount importance pork, as it affects storage, retail, consumer acceptance. For purpose, fatty acid profile,...
Background: The high dairy production of Polish Holstein Friesian (PHF) cows determines energy requirements in the early stages lactation. Unfortunately, it is very often difficult to meet this demand through feedstuffs; therefore, homeostasis may be disturbed and metabolic diseases occur, causing a majority cows’ health problems. Breeders are, looking for alternatives PHF breed using crossbreeding. Methods: This experiment involved 30 × Swedish Red (SRB) crossbred hybrid cows, divided into...
This study aimed to formulate a diet for finishing lambs that included chestnut shells, an underexploited by-product of industry, and evaluate its effects on in vivo performance meat quality. Twenty-eight male (race Romane; 27.9±2.7 kg bodyweight) were divided into 4 groups fed different pelleted diets: one control, containing shells (CNS), sainfoin, both. After 21 days feeding trial, at slaughter, rumen abomasum digesta sampled the analysis fatty acid (FA) profile, was analysed FA vitamins...
