Eighty-five randomly selected equestrian saddles were tested and evaluated. They were observed in 129 uses. Saddles of different manufacturers were evaluated after 25 min of training. Thermal images were taken under constant conditions from a distance of 1 m. The camera emissivity was 0.95 with a reflected temperature range of 26-37 °C. The maximum contact value of the saddle panels with the horse's body was 81.34% of their surface area. In all cases of measurement, the saddle panels showed asymmetry of contact with a range of detected values from 0.32% to 30.46% (P < 0.001). In 20.16% of cases, the contact was measured in the spinal canal region (min. 0%, max. 67.5%). In 7.75% of cases, saddle bridge was detected. None of the saddles tested showed 100% fitting (P < 0.001). Saddles with contact in the spinal canal and a bridge at the same time were completely excluded from the evaluation. The saddle panel contact exceeding 70% of the area and a tolerance for asymmetry not exceeding 5% were regarded as suitable for use. In considering a combination of all these parameters, only nine out of 129 cases of use were fully compliant. No correlation between saddle age and occurrence of the observed defects was demonstrated. It was found that thermographic evaluation can be proposed as a tool to standardise the assessment of saddle suitability prior to its use for a specific horse.

It was carried out within the period 2017-2020. The animals subject to the study were between two and eight years old. The temperament was visually evaluated following a scoring system from 1 to 5. The assessment method involved the behavioural reaction of the cows upon manipulation, passing through a chute and fixation into a cattle crush. The temperament of cows reared in two different systems - intensive and semi-intensive farming was compared. The temperament of the Aberdeen Angus cows had an average rate of 2.74 ± 0.04. The cows which had frequent contact with people had a calmer temperament. The manner of rearing (P < 0.001) as well as the age group (P < 0.001) had a significant influence on the parameter examined. The young animals were calmer and got accustomed to working in a crush more easily when they were reared together with cows of different ages.

A total of 60 barrows and gilts (initial body weight 28.4 ± 0.4 kg) were allotted to four dietary treatments: control (CON), lignocellulose (LC), mycelium (MYC) and corn gluten feed (CGF). Diets were calculated to provide balanced available nutrient contents. Including MYC in the diet resulted in an increased average daily gain (P < 0.05) compared to CON and CGF, and improved gain to feed ratio (P < 0.05) compared to LC. Pigs in CON (P < 0.05) ate the fewest but largest meals, whereas treatment CGF (P < 0.05) showed the opposite effect, resulting in the same daily feeder occupation time. Regarding intestinal physiology, in ileum, no differences were observed between the contents of short chain fatty acids (SCFA), lactic acid and biogenic amines. In the colon, MYC showed an increased concentration of acetic acid (P < 0.05) as well as the total content of SCFA (P < 0.05), compared to LC and CGF. Distinct fermentation profiles of ammonia were recorded in ileal and colonic digesta, although contents remained below harmful concentrations. Morphometrical measurements showed differences between the fibre sources LC and MYC, as well as LC and the CON in all investigated gut sections. These results provide evidence that the inclusion of specific dietary fibre sources/contents can positively influence the gut morphology and performance of pigs. However, further studies are needed regarding the mode of action and physico-chemical characteristics of the different fibre sources as a precondition for their successful application in pig diets.

Thirty-two healthy 7-day-old piglets were randomly divided into four treatment groups: control group (basal diet), LB2 group (supplemented with 1 × 108 CFU/pig/day L. zeae LB2), ETEC group (infected with 1 × 1010 CFU/pig/day ETEC) and ETEC+LB2 group (LB2 supplementation + ETEC infection). Intestinal contents were collected for DNA extraction and Illumina sequencing. Significant result was observed for alpha diversity in the four intestinal sections, and both ETEC infection and LB2 supplementation showed a higher Chao1 alpha diversity. At the phylum level, Firmicutes and Bacteroidetes were dominant in the healthy piglets, while Proteobacteria were dominant in the ETEC-infected piglets. At the genus level, ETEC infection decreased the abundance of Prevotella, Ruminococcaceae, Lactobacillus, Alloprevotella, Flavobacterium, and Sutterella and increased the abundance of Actinobacillus. The LB2 supplementation reduced the abundance of Ruminococcaceae, Actinobacillus, Porphyromonas, and Alloprevotella, and increased the abundance of Prevotella and Lactobacillus. Both ETEC infection and LB2 supplementation affected several functional pathways associated with cellular processes, environmental information processing, genetic information processing, diseases, metabolism, and organismal systems. In summary, ETEC infection induced dysbiosis of the gut microbiome in piglets, while L. zeae supplementation could positively regulate the gut microbiome during ETEC infection. Therefore, L. zeae LB2 may be an ideal probiotic for the prevention or treatment of ETEC infection.
