“…The average drip losses that were determined in the not weighed samples were 0.95% within 24 h, 1.30% within 48 h, and 1.38% within 72 h, whereas the weighed samples were 1.72% within 24 h, 2.70% within 48 h, and 3.62% within 72 h. Although there is considerable variability in WHC between animals, the following comparison with different species should give us deeper insight into the drip loss values that were obtained by different EZ-DripLoss methodologies. Greater average drip loss values of not weighed samples were found with beef [ 11 ] and deer meat [ 12 ] than the ones of the present technical report. Mergeduš et al [ 11 ] found that the average drip loss of meat from bulls that were fattened under commercial conditions was 1.40% within 48 h of storage period.…”

“…This methodology implies the necessity of weighing an empty container, the container with a meat sample and drip loss, and that same container only with drip loss, after removing the meat sample [ 6 ]. Drip loss assessment using the standardized EZ-DripLoss methodology has been investigated in pork [ 3 , 10 ], beef [ 11 ], and deer meat [ 12 ].…”

The EZ-DripLoss method is relatively new gravimetric method that is used for the determination of excessive drip in meat. The literature reports diversity regarding the use of EZ-DripLoss methodology. In the standardized EZ-DripLoss method, drip loss is calculated as the change in the container weight, whereas in the modified EZ-DripLoss method, it is calculated as the change in sample weight. This technical note aimed to research the relationship between these two methods on chicken breast meat (40 broilers from the line Ross 308) during the measurement interval of 24, 48, and 72 h. The results showed statistically a significant positive linear increase in drip loss values regardless of the used method during all of the investigated measurement intervals. At 24, 48, and 72 h of storage, the average drip loss in the weighed samples was 0.77, 1.40, and 2.23 percentage points greater than in the not weighed samples (p < 0.0001), respectively. A strong and positive estimate of correlation coefficients between the drip loss of weighed and not weighed samples was found after 24 h (r = 0.95), 48 h (r = 0.92), and 72 h (r = 0.86). This technical report indicates that the used EZ-DripLoss methodology highly influences the drip loss in chicken breast meat and the comparisons of the EZ-DripLoss results should be performed with great caution.

“…Moreover, Taha et al [ 9 ] reported that adding chestnut tannin extract (CTE) to ryegrass silage reduces ammonia nitrogen (NH 3 -N) concentration in lamb rumen. In contrast, Mergeduš et al [ 10 ] discovered that supplementing CTE with a low-protein diet elevates growth performance and nutrition efficiency in bulls, without affecting slaughter performance or meat quality. The differences in these findings could result from the tannin dosage, source, type, animal species, health status, and feed composition [ 11 ].…”

Tannins as plant extracts have emerged as promising and potential alternatives for antibiotics in modern livestock cultivation systems. This study investigates the effect of dietary chestnut tannin extract (CTE) in finishing Tan lambs. Twenty-seven male Tan lambs were randomly divided into three groups: (1) control group (CON; basal diet); (2) low-dose CTE group (LCTE; basal diet + 2 g/kg CTE, dry matter [DM] basis); (3) high-dose CTE group (HCTE; basal diet + 4 g/kg CTE, DM basis). The HCTE group exhibited markedly higher average daily gain (ADG) and DM intake than CON (P < 0.01). The ruminal total volatile fatty acid concentration increased linearly with increasing CTE supplementation (P < 0.01), while the opposite trend was observed for butyrate molar proportion (P < 0.01). Upon increasing CTE dosage, plasma glucose, high-density lipoprotein cholesterol, glutathione peroxidase, and superoxide dismutase content increased linearly (P < 0.05), whereas low-density lipoprotein cholesterol and urea nitrogen decreased linearly or quadratically (P < 0.05), respectively. A linear increase was also observed in ruminal t6 C18:1 and t9, c12 C18:2 proportions (P < 0.01), and plasma C18:2n-6 and n-6 polyunsaturated fatty acids proportions with increased CTE supplementation (P < 0.01). In the longissimus dorsi muscle, the atherogenic index decreased linearly (P < 0.05), while c11 C18:1 and C20:5n-3 increased linearly (P < 0.05). Moreover, c9, t11 conjugated linoleic acids proportion increased in subcutaneous fat with CTE supplementation (P < 0.01). In conclusion, Dietary CTE enhances the ADG of finishing Tan lambs in a dose-dependent manner, modulates plasma metabolites and antioxidant capacity, and improves rumen fermentation and body fatty acid composition. These results provide a reference for the rational application of CTE in ruminant production.

“…Moreover, this implementation serves as a preventive measure against boar taint by minimizing intestinal skatole production . The supplementation of HT in the diet of pigs, chickens, and bulls has been shown to accelerate their growth rate and improve gastrointestinal well-being, as evidenced by several studies. − Additionally, it contributes to a reduction in enteric methane emissions in llamas and bulls …”

Castanea sativa wood is a rich source of hydrolyzable tannins, known for their diverse bioactivities. To investigate these bioactive properties further, it is crucial to isolate and characterize hydrophilic compounds effectively. To address this issue, we developed a centrifugal partition chromatography (CPC) method and applied it to an aqueous C. sativa wood extract. We determined the partition coefficients (K D ) of the six major compounds using four butanol-/ water-based biphasic solvent systems. Initially, we utilized the nbutanol/propanol/water (3:1:4, v/v/v) systems for the first fractionation step. Subsequently, we employed the water/methyl tert-butyl ether/butanol/acetone (8:5:3:4, v/v/v/v) system to fractionate moderately and highly hydrophilic fractions. We calculated the K D values for major compounds of the most hydrophilic fractions using the butanol/ethanol/water (4:1:5, v/v/v) and butanol/isopropanol/water (2:1:3, v/v/v) systems. In total, we isolated 23 compounds through a combination of CPC, size exclusion chromatography, and preparative HPLC. Among these compounds, six have never been previously described. We characterized them by 1D and 2D NMR experiments and high-resolution mass spectroscopy acquisitions.
