The circadian rhythm of body core and surface temperature in 10 Comisana sheep kept under a natural photoperiod (06:30/19:00) was evaluated. Every 3 h for 24 consecutive hours rectal temperature (RT) and foot temperature were recorded. Particularly, foot temperature was recorded by infrared thermography, an ideal technique for evaluating the temperature not only at one point but also at the eight points as follows: in the right front of the interdigital area (FA1), in the left front of the interdigital area (FA2), in the right rear of the interdigital area (RA1), in the left rear of the interdigital area (RA2), in the right front of the interdigital...

The relationship between a potential marker for mastitis, CGIL4, and the breeding value for somatic cell count (SCC) was analysed in a panel of Czech Simmental and German Holstein sires. Genotyping was done by PCR/RFLP. The analysis did not reveal a significant difference in breeding values for SCC depending on the genotype of CGIL4, even though other authors confirmed the relationship between this marker and clinical mastitis. Further investigations will be necessary to clarify the relevance of the marker for selection against mastitis.

This study was conducted to investigate the effects of selenomethionine (Se-Met) and sodium selenite (SS) supplementation on meat quality, selenium (Se) distribution, and antioxidant status in broilers. A total of 360 seven-days-old Ross 308 broilers of an average body weight 162 ± 0.59 g were randomly allotted to three treatments, each of which included three replications of 40 birds. The treatments included a control diet containing 0.04 mg Se/kg and other two diets that contained 0.15 mg Se/kg supplemented by SS or Se-Met. The experiment lasted for 42 days. Selenium supplementation improved (P < 0.05) the Hunter a value of breast...

The objective of the present study was to research the effects of different supplemented dietary sources of n-3 polyunsaturated fatty acids (n-3 PUFA) to produce n-3 enriched meat on growth performance, meat quality, serum antioxidative status, immune response and tibia bone characteristics in Japanese quail. Three hundred 1-day-old Japanese quail chicks were randomly weighed and divided into five dietary treatments containing 0% oil (C, negative control), 2% vegetable oil (VO, positive control), 2% linseed oil (LO), 2% fish oil (FO) and a mixture of 1% linseed oil +1% fish oil (LO+FO). Body weight and feed consumption were recorded. Fatty acid profile,...

The application of Thamnidium elegans fungal strain CCF 1456 (TE) for effective utilization of various agroindustrial materials creates new perspectives for animal cereal diets enriched with microbial γ-linolenic acid (GLA). Diets consisting of lucerne hay (LH) plus prefermented cereals (wheat bran/spent malt grains, WB+TE or WB+TE enriched with sunflower oil, WB+SO+TE in the first experiment and ground maize grains, GC+TE in the second experiment) were used in the artificial rumen. We examined their effect on the rumen fermentation pattern and lipid metabolism. The diet affected the results of degradability of dry matter, organic matter,...
