Their impact can be mitigated not only by changes in technologies, management and treatment, but also by breeding and selection of more resilient cows. General resilience encompasses the animal's capacity to cope with environmental, social and disease challenges. It is described as the capacity of the animal to be minimally affected by a disturbance or to rapidly return to the physiological, behavioural, cognitive, health, affective and production states that pertained before exposure to a disturbance. As disturbances can be of different natures, general resilience is a composite trait consisting of different resilience types according to the nature of the disturbance. Resilience can be quantified through time series data that capture fluctuations in the daily performance. Recent studies have worked with deviations in the daily milk yield and daily live weight from optimal performance or have focused on the assessment of the daily activity in terms of the daily step count. To observe the duration and magnitude of the response to perturbance, two indicators were suggested: the autocorrelation (rauto) and the natural logarithm of deviations (LnVar). Based on the daily milk yield deviations, both indicators have shown sufficient genetic variabilities with the estimated heritability ~0.1 for rauto and ~0.2 for LnVar. Low values of both indicators were genetically related to better udder health, better hoof health, better longevity, better fertility, higher body condition score, less ketosis but also lower milk yield level. The selection for improved resilience could benefit from the use of genomic information as several genes and biological pathways associated with disease resilience and resilience to heat stress have already been identified. The presented results suggest that the integration of resilience into the cattle breeding programmes would improve the capacity of the dairy industry to cope with global climate change.

Pedigree data were collected from the national studbooks. Pedigree data for 2 521 horses were used in the analysis, for a reference population covering live animals in the current population. The average generation interval was 10.78 ± 0.36 (BH) and 12.12 ± 0.59 (SRB) years. The equivalent complete generations ranged from 5.49 (BH) to 14.86 (SRB). The average inbreeding values were 3.96 (BH) and 2.12 (SRB), whereas the average relatedness values were 9.24 (BH) and 4.13 (SRB). Values for fe, fa, fg and the fe/fa ratio were 21, 12, 6.031 and 1.75 in BH Lipizzan horses, and 79, 20, 9.766 and 3.95 in SRB Lipizzan horses. The number of ancestors explaining 50% of genetic diversity in the BH and SRB reference populations was five and eight, respectively. The effective population sizes obtained from regression on the birth dates were 43.67 (BH) and 211.78 (SRB). The investigated genetic variability parameters were higher in the SRB Lipizzan population than in the BH population. The results of pedigree and genetic structure research indicate the need for a comprehensive approach to monitoring to improve future breeding and genetic diversity in the BH and SRB Lipizzan populations.

Ninety-six farrowing highly prolific sows (Topigs 20) were assigned to two dietary treatments from day 107 ± 2 days of gestation until weaning: control diet and the same diet containing 15 g/day of SPM. Sows fed SPM diet tended to have lower backfat losses (P = 0.06) than control sows. No difference was observed in daily feed intake. No difference in litter birth weight or number of piglets per litter was observed. In sows fed SPM, average daily gain and weaning body weight of piglets were increased (P < 0.05). Haematochemical parameters, haptoglobin and blood total antiradical activity were not affected (P > 0.05) by dietary treatment. The paraoxonase-1 activity was higher (P < 0.05) in SPM sows than in the control. At the subsequent farrowing, the total number of piglets born was higher (P < 0.05) in sows fed SPM than in the control. Overall, these data suggest that dietary plant polyphenols and brown seaweeds improved the weaning weight of piglets and the total number of piglets born at the subsequent farrowing, modulating oxidative stress in lactating highly prolific sows.

One hundred eighty crossed pigs (Landrace × Yorkshire × Duroc), weighing approximately 70 kg, were divided into four groups of 15 head (eight barrows and seven gilts) per pen, and the experiment was replicated thrice. The basal diet (C) was supplemented with 0.5% (T1), 1.0% (T2), and 1.5% (T3) of dried powdered wormwood, and the pigs were fed an experimental diet for six weeks. The average daily weight gain and feed efficiency were significantly higher (P < 0.05) in treatments than in C. On the contrary, the total cholesterol concentration was significantly lower (P < 0.05) in treatments than in C. Additionally, the high-density lipoprotein cholesterol concentration was significantly higher (P < 0.05), and the carcass grade was better (P < 0.05) in the treatments than in C. The ether extract content of the longissimus dorsi (LD) muscle was lower (P < 0.05) in T2 and T3 than that in C. In contrast, the unsaturated fatty acid (USFA) composition in LD muscle was higher (P < 0.05) in the treatments than in C. Additionally, the marbling and flavour of cooked meat were better (P < 0.05) in the treatments than in C. The dietary addition of wormwood increased (P < 0.05) lightness and yellowness of the surface meat colour and decreased (P < 0.05) juiciness of the LD sensory evaluation. Therefore, the dietary addition of wormwood improved growth performance, feed efficiency, carcass grade, USFA composition, and oxidation of protein and lipids in the LD muscle of growing-fattening pigs.
