Experiences during gestation can alter the mother’s behavior and physiology, thereby potentially affecting the behavioral and physiological development of the offspring. In livestock, one common challenge for pregnant animals is lameness: a multifactorial condition that causes pain, stress, resulting in poor welfare outcomes. Since maternal pain can affect offspring development, we aimed to quantify the behavioral response in 142 piglets born from sows with different degrees of lameness during pregnancy. Gait scores of 22 pregnant group-housed sows were assessed six times at 2-week intervals. Lameness scores varied from 0 (no lameness) to 5 (most severe lameness score). Saliva samples and behavior were assessed in the sows throughout pregnancy. Sows were moved to individual farrowing pens and placental tissue was collected for glucocorticoid assessment. At 28 days of age, piglets were weaned, weighed, and regrouped by body size and sex. Skin lesions were counted for each piglet on days 28, 29, and 30 after birth. During open field and novel object tests on day 30, the vocalization and activity levels were evaluated. Piglet data were grouped by the lameness score of the sows as G1 (without lameness), G2 (moderate lameness), and G3 (severe lameness). Data analysis included ANOVA or Kruskal–Wallis tests and pairwise comparisons which were performed using Tukey and Kramer (Nemenyi) test with Tukey-Dist approximation for independent samples. G2 piglets were heavier than G3 at weaning. G1 piglets had fewer skin lesions at days 28 and 29 than G2 piglets. Moreover, G1 piglets vocalized more than G2 when they were subjected to the combined open field and novel object test. We did not identify differences among sows showing different lameness scores in the concentration of placental or salivary glucocorticoids. Lameness in pregnant sows altered the offspring’s weight gain, number of skin lesions and vocalizations, together showing evidence that lameness in sows affect offspring performance and behavior.

Pregnant sows from commercial pig farms may experience painful states, such as lameness, an essential indicator in assessing sow welfare. We investigated the effect of lameness during the last third of pregnancy on reproductive performance and placental glucocorticoid concentrations in sows. Periodic locomotion assessments were carried out on two commercial pig farms using a validated 0–5 scoring system (from 0: normal locomotion; to 5: a downer animal). Sows from both farms (N = 511) were grouped based on their average locomotion scores. On Farm 1, 30 sows were selected and grouped as either Not Lame (NL = 16; $\overline{X}$ = 0–1) or Lame (L = 14; $\overline{X}$ > 1). On Farm 2, 39 sows were selected and grouped as either Not Lame (G1 = 12; $\overline{X}$ = 0–1), Moderately Lame (G2 = 13; $\overline{X}$ = 1.1–2), or Severely Lame (G3 = 14; $\overline{X}$ ≥ 2.1). Reproductive data (gestation length, litter weight, average piglet weight, litter size, and the number of piglets born alive/mummified/stillborn) were recorded on both farms. Moreover, on Farm 2, piglet intrauterine growth restriction score and the number of piglets dead during the first week were also recorded, and placenta samples were collected to determine their cortisol/cortisone concentrations. A linear mixed model was used to analyze the data. The proportion of lameness in pregnant sows (N = 511) was >40%, and the gestation length tended to decrease with the presence of lameness (p < 0.1) in both farms. G2 sows had a higher placental cortisol/cortisone ratio than G1 and G3 sows (p < 0.01). In conclusion, lameness was high in the sows assessed, which may decrease sow gestation length and reduce placental efficiency in protecting the offspring from the sows’ stress response.

Donkeys were traditionally used as draft animals for transporting cargo, as a means of transportation, and for riding purposes before the advent of mechanization. Following this historical shift, their economic significance declined, making them targets for other industries, such as Chinese industries that use donkey skin to extract gelatin (ejiao). Since donkey slaughter is not a regulated activity in Brazil, the welfare and survival of donkeys are increasingly at risk as demand for their skins rises. Complaints filed by public agencies in Brazil have raised concerns about the donkey slaughter chain in the country, questioning whether this production system operates under regulated standards or follows an extractive model. The objective of this study was to evaluate the production system of donkeys destined for slaughter in Brazil through physical and hematological assessments, aiming to identify potential systemic failures that may compromise animal welfare. To achieve this, physical and hematological evaluations were conducted on a group of 104 abandoned donkeys. The physical assessments aimed to determine the animals’ sex, estimate their age, and evaluate their body condition score (BCS). These were conducted through examination of the genital organs and dental arcades, with the neck evaluated using a scale from 0 to 4 and the body condition assessed using a scale from 1 to 9, respectively. Hematological assessments included the measurement of hematocrit (HT), total plasma protein (TPP), and plasma concentration of fibrinogen. Most of the donkeys were entire males (n = 50–48.08%), with a median age of 15.1 years. The body condition score was 2 or 3 (n = 36, 52%), and the neck condition score was 1 (n = 3, 37.5%). The majority of animals had hematocrit levels above 25%, total plasma protein levels below 7.5 g/dL, and fibrinogen levels exceeding 400 mg/dL. Based on the data analysis, the animals were characterized as being in poor health, since all groups exhibited altered body and neck condition score, plasma fibrinogen concentration, and total plasma protein. These parameters may be indicative of malnutrition and systemic inflammation, even though other laboratory results showed no signs of disease. Activities characterized by mistreatment contribute to an unsustainable extractive model.

Experiences during gestation can alter the mother’s behavior and physiology, affecting the development of the offspring, including the organization of their brains and emotional system. In livestock, one common challenge for pregnant animals is lameness: a multifactorial condition that causes pain, stress, and compromises welfare. Since pain experienced during gestation can affect offspring development, we aimed to quantify the emotional outcomes of 156 piglets born from sows with lameness during pregnancy. Gait scores of 22 pregnant group-housed sows were assessed six times at two-week intervals. Lameness scores varied from 0 (no lameness) to 5 (most severe lameness score). Saliva samples and behavior were assessed in the sows throughout the pregnancy. Sows were moved to individual farrowing pens and placental tissue was collected for glucocorticoids assessment. At 28 days of age, piglets were weaned, weighed, and grouped by body size and sex. Skin lesions were counted in each piglet on days 28, 29, and 30 after birth. During open field and novel object tests the vocalization and activity levels were evaluated. Piglet data were grouped by the lameness score of the sows as G1 (lameness score 0-1), G2 (lameness score 2-3), and G3 (lameness score 4-5). Data analysis included ANOVA or Kruskal-Wallis tests and pairwise comparisons were performed using Tukey and Kramer (Nemenyi) test with Tukey-Dist approximation for independent samples. G2 piglets were heavier than G3 at weaning. G1 piglets had fewer skin lesions at days 28 and 29 than G2 piglets. Moreover, G1 piglets vocalized more than G2 when they were subjected to the combined open field and novel object test. We did not identify differences in the concentration of placental or salivary glucocorticoids among the sampled sows showing different lameness scores. Lameness in pregnant sows has negative effects on the offspring, affecting weight gain, increasing aggressiveness, altering vocalization during an open field, and novel object tests in piglets.
