The aim of this study was to investigate antibacterial effects oregano and thyme essential oils (EOs) on some food-borne bacteria. GC-MS analysis EOs performed in order determine their composition phenols were predominant constituents. investigation the Salmonella Enteritidis, Thyphimurium, Staphylococcus aureus, methicillin resistant Escherichia coli Bacillus cereus, MICs determined by broth microdilution method. exhibited activity against all tested microorganisms.

Fats in animal and human nutrition are a common subject of research. These studies most often pay attention to particular fat groups (saturated, unsaturated, polyunsaturated fats or grouped by the length their fatty acid chains into short, medium long chain acids). Medium acids (MCFAs) have two main sources: milk coconut oil. To date, research has shown these positive effects on health, production, feed digestibility lower body muscle broilers swine. MCFAs possess antibacterial,...

The present study was conducted to assess effects of selenium (Se)-yeast supplementation on glutathione peroxidase activity, Se levels in tissues, growth performance, carcass, and meat composition broilers. A total 275 one-d-old Cobb 500 broilers both sexes were randomly allotted 1 5 treatments during a 42-d period. differed only content: group had no additional (background only); groups 2, 3, 4 received 0.3 mg/kg added from the beginning trial until d 21, whereas second half (from 22 42),...

The present study aimed to evaluate the antioxidant capacity of ethanolic extracts from post-harvest sunflower and maize stalk residues, their impact on chemical composition, physicochemical parameters, lipid oxidative stability, microbiological properties, sensory characteristics pork liver pâtés over a 90-day storage period. Four formulations were prepared: control group (CON), batch with butylated hydroxytoluene as synthetic (BHT), 1% extract residues (SSRE), (MSRE). MSRE had higher total...

Abstract The study aimed to compare the chemical composition (proximate, mineral, fatty acid, and amino acid composition) nutritional value of meat from three deer species (fallow deer, red roe deer). A total eighteen male carcasses were collected. Proximate ( M. longissimus lumborum ) did not differ among species, while affected content most minerals (Ca, P, Na, Mg, Fe, Mn, Zn). In present analysis profile showed that polyunsaturated (PUFA) saturated ratio n-6/n-3 PUFA were, for all within...

The objective of this study was to determine the effect breed line and age on pH in broiler chicken breast muscles. values m. pectoralis major muscle were compared within 6 groups - each (Cobb, Ross, Hubbard) divided into two aged 42 50 days. recorded 15 minutes, 24 48 hours after slaughtering. Older broilers showed significantly lower than younger ones. Interactions between found, except for hours. Meat quality can be estimated quickly by determining pH-value meat.

The effect of different modified atmosphere packaging regimes on the behavior Salmonella spp. minced meat was studied. Minced experimentally contaminated with a cocktail (S. Enteritidis, S. Typhimurium, Infantis and Arizonae), packaged under vacuum or initial headspaces containing 20%O2/50%CO2/30%N2 20%O2/30%CO2/50%N2) stored at 3±1°C for 12 days. Samples were analyzed spp., viable lactic acid bacteria count every third day. counts decreased during storage in all types, reductions about...

Grains have great agronomic and economic importance they are oneof the most important plants. Triticale is modern cereal grain, hybrid of wheat andrye, which inherited ability rye to survive high frosts, but has a higherprotein value than rye, while higher grain yields increased tolerance diseaseswere from wheat. The way in triticale will be used depends on thecharacteristics variety. varieties large uniform grains whichhave more proteins then starch as concentrated feed for poultry,...

Abstract The antioxidant stability of minced pork treated with thyme and oregano essential oils (EOs) was determined. Minced containing different concentrations (0%, 0.3%, 0.6%, or 0.9%) (TEO) oil (OEO) packaged under vacuum modified atmosphere (MAP) (30%O 2 /50%CO /20%N ) evaluated within 15 days refrigeration (3 ± 1 °C) storage. EOs were examined for scavenging capacity toward 2,2‐diphenyl‐1‐picrylhydrazyl, nitric oxide radicals, hydroxyl, inhibition lipid peroxidation ferric ion reducing...

Abstract Consumers’ knowledge about proper household practises during food handling and storage are deemed insufficient. Therefore, the aim of our study was to investigate conditions in refrigerators (temperature, hygienic conditions) consumer good practises. This included 100 households from Belgrade area. All participants were interviewed using a standardized questionnaire. The internal temperature measured at three points: top bottom shelves refrigerator door. average 9.3°C. recorded...

Selection of optimal hybrid Pekin duck and housing system could improve yield quality meat.The aim this study was to investigate the effects two rearing systems (intensive vs semi-intensive housing) on growth performance, carcass quality, selected physical meat traits commercial strains ducks.The performed 240 one-day-old ducklings different (120 STAR 53 medium 120 SM3 heavy hybrid) during a 49-day period.Half birds (120) were reared in complete confinement floor system), while remaining...

The aim of the present study was to assess effects selenium (Se)-yeast diet supplementation on performance and carcass composition in ducks. performed 240 1-day old ducklings same origin (Cherry Valley hybrid), during a 49-day period, which were fed diets supplemented with following four different levels Se yeast (ALKOSEL® R397): groups at 0 mg/kg as-fed, 0.2 mg/kg, 0.4 0.6 mg/kg. Growth (bodyweight, daily weight gain, feed intake, feed-conversion ratio) characteristics (hot cold weight,...

In this paper, gravimetric work performed in the territory of Serbia is shown chronologically from end nineteenth century until present. The first work, which was based on data pendulums, presented briefly. Details are provided establishment order network 1952 and a basic created 10 years later. A review detailed measurement, simultaneously with these works for establishing networks, also given. Special attention dedicated to measurements using absolute gravimeters that were 2007, but new as...

Because of the importance different packaging methods for extension fish shelf life, as a highly perishable food, aim present study was to examine effect vacuum and modified atmosphere on total Enterobacteriaceae lactic acid bacteria counts cold-smoked Salmon trout (Oncorhynchus mykiss) stored at 3°C during six weeks. Trout fillets were vacuumed packaged (VP) or in one two atmospheres, with gas ratio 50%CO2/50%N2 (MAP1) 90%CO2/10%N2 (MAP2) analysed days 0, 7, 14, 21, 28, 35 42. Both...
