Effect of Broilers Chicken Diet Supplementation with Natural and Acidified Humic Substances on Quality of Produced Breast Meat.

This study was conducted to examine the effect of two humic substances (HS) supplemented in broilers' diet on the breast meat quality of broiler chickens. In this experiment, 120 pieces of one-day-old COBB500 broiler chickens were used. Broilers were divided into three groups, each containing 40 birds with three replications (13, 13, and 14 per one pen).

Content of selected metals in muscle of cyprinid fish species from the Nitra River, Slovakia.

Objectives: This study presents a rate of bioaccumulation of some metal concentrations in the muscle of five common cyprinid fish species (gudgeon - Gobio gobio, Europen chub - Leuciscus cephalus, barbel - Barbus barbus, roach - Rutilus rutilus, and nase - Chondrostoma nasus).

Design: Besides, correlations among selected metals as well as standard length and total weight and order of metal accumulation in the fish muscle were determined.

Results: Recorded metal concentrations (mg/kg wet weight basis) ranged as follows: Fe 4.

The effects of long-term cadmium exposure in turkeys: accumulation and zinc prevention.

Experiments with turkeys were conducted to determine the effects of long-term ingestion of Cd (2.0 mg Cd/day/turkey) on its accumulation in the tissues and organs. The cadmium was found especially in the muscles, livers and kidneys.

Concentrations of selected trace elements in organs and tissues of livestock from a polluted area.

The occurrence of cadmium (Cd), nickel (Ni) and lead (Pb) from industrial emissions were determined in the muscle and liver of cattle from agricultural farms near an industrial plant in Eastern Slovakia. In this study cows (n = 25) were slaughtered and the concentrations of Cd, Ni, Pb were analyzed with a the atomic absorption spectrophotometer. Levels reaching the highest permissible hygiene limits for toxic metals Cd, Pb and Ni were determined in 50 samples.

The effect of the probiotic strain Enterococcus faecium DSM 7134 in combination with natural humic substances on performance and health of broiler chickens.

The present study investigated the effect of the probiotic strain Enterococcus faecium DSM 7134 (2 x 10(7) cfu per g of feed) (probiotic group), natural humic substances (7g x kg(-1) feed) (HS group), and the combination of both (probiotic + HS group) on the performance, serum biochemistry, and biological activity of leucocytes of broiler chickens. Average body weight of chickens in different phases as well as throughout the observation period under different treatments did not differ significantly. Final body weight and feed conversion ratio (FCR) reached in 41 days of trial were 2542.

Effect of oral cadmium and zinc application on leukocytes biological activity in Japanese quails (Coturnix coturnix japonica).

Objective of this study was to investigate changes in biological activity of blood leukocytes in Japanese quails, caused by zinc and cadmium administration. Four groups of Japanese quails were used. Three experimental groups of quails were exposed either to Cd (0.

The effect of cadmium in combination with zinc and selenium on ovarian structure in Japanese quails.

In this study the effect of cadmium, cadmium+selenium and cadmium+zinc administration on the ovarian structure in Japanese quails was studied. The morphometric analysis of the relative volume of primary follicles detected the highest value in control group with a similar value in the group with administration of cadmium with selenium. Lower relative volume is reported in group with cadmium and zinc administration and the group with simple cadmium administration (P < 0.

Testing two Lactobacillus plantarum and Lactobacillus acidophilus strains for their suitability as a lipoid probiotic.

Two strains of lactobacilli (Lactobacillus acidophilus T-135 and Lactobacillus plantarum 4/97) were selected in order to study their inhibitory properties against frequent udder pathogens (Escherichia coli, Staphylococcus aureus, Streptococcus agalactiae, Streptococcus uberis, Salmonella enteritidis and Bacillus pumilus), their production of organic acids as well as their ability to survive on the teat skin, the teat duct mucosa and in a lipoid emulsion. Both strains inhibited the tested pathogenic microbes and survived on the investigated surfaces and in an emulsion for more than 6 hours and 11 days, respectively.
