Summary: High obesity rates around the world point to an urgent need for effective obesity prevention measures. Animal studies suggest that the effects of essential polyunsaturated fatty acids on adipogenesis may be mediated through various mechanisms. Divergent findings from human clinical trials and observational studies suggest that recommendations for humans regarding PUFA and obesity risk are not yet possible.

Summary: A study found that dietary supplementation with EPA-pPE can significantly change the fatty acid composition in the brain and liver, especially in increasing the content of DHA. EPA-pPE has a more significant effect on increasing DHA compared to EPA-PC, making it a good nutritional supplement to increase DHA levels in n-3 PUFA-deficient offspring's brains.

Summary: The increase in fetal requirements of long-chain polyunsaturated fatty acids during pregnancy alters maternal fatty acid metabolism, and FADS gene polymorphisms may change blood fatty acid composition differently. The study investigated the relationship between a FADS1 SNP and maternal serum LCPUFA levels in Japanese pregnant women. The results showed that LCPUFAs significantly decreased as pregnancy progressed and certain fatty acids were significantly associated with the number of minor FADS1 SNP alleles, indicating genotype effects become more obvious later in pregnancy.

Summary: This study examined the composition and contents of fatty acids (FA) in fillets of seven strains of rainbow trout. The results showed that the diet composition and genetics played a role in the FA composition of the fish. The Steelhead strain of rainbow trout demonstrated a higher ability to regulate its FA composition, particularly regarding the important acids EPA and DHA. Furthermore, FA markers were identified that can be used to differentiate between wild and farmed rainbow trout.

Summary: This study analyzed the intake of polyunsaturated fatty acids (PUFAs) during complementary feeding (CF) in very low birth weight (VLBW) infants and its impact on neurodevelopment. The results showed that higher intake of total PUFAs, docosahexaenoic acid (DHA), and arachidonic acid (AA) was associated with improved cognitive and motor function at 12 months of age. However, the dietary intake of AA and DHA did not meet the recommended levels, highlighting the need to increase PUFA, DHA, and AA intake during CF for better neurodevelopmental outcomes in VLBW infants.

Summary: The association between omega-3 intake and brain volume, specifically the hippocampus, total grey matter, total brain volume, and white matter lesion volume, was observed in several studies. However, mixed findings were reported and the association appeared to be brain region-dependent. More research is needed to formulate specific recommendations for omega-3 intake to support brain health.

Summary: Early feeding has a significant impact on the colon microbiota of piglets, while no effect was seen in the jejunal and ileal microbiota. Early-fed piglets showed decreased pH in the caecum and colon, along with increased short-chain fatty acid concentrations. Additionally, early feeding altered the weights and lengths of intestinal tract segments, as well as the villus-crypt ratio in jejunal mucosa and the abundance of proliferative cells in colon mucosa.

Summary: This study investigated the social behaviors and early social styles of suckling piglets. Three social styles, including inactive, active, and avoiders, were identified. The allocation to specific social styles was influenced by sex and remained stable over time for the inactive and active styles. Haptoglobin and growth rate were found to be higher in active pigs compared to inactive pigs. These findings suggest the existence of transient social styles in piglets, which may be related to sexual dimorphism or health status.

Summary: Damaging behaviors, such as tail and ear biting, are common in pig production and negatively impact welfare and performance. Poor health and tail damage show high correlations within and between pig farms. There are common risk factors for both tail-biting and health problems, including respiratory, enteric, and locomotory diseases. Limited evidence supports two potential causal mechanisms linking damaging behaviors and health problems, either poor health increasing the risk of tail-biting or tail-biting causing poor health.

Summary: Improving pig welfare through upgrades in housing environment, including multi-litter housing, delayed weaning, extra space allowance, and environmental enrichment, has been shown to reduce stress levels and improve cognitive resilience in pigs. Alternative housing conditions result in lower cortisol levels and tear staining area, indicating better overall welfare. Pigs in the alternative housing system exhibit lower heart rate, higher heart rate variability, and higher vagal activity during a stress challenge, suggesting reduced sensitivity to stressors. Furthermore, the alternative housing system appears to improve long-term memory in pigs. Providing social and environmental enrichments that better fulfill the pigs' essential needs is beneficial for pig welfare.

Summary: This study aimed to evaluate the effects of different incubation lighting conditions on hatching performance, blood hormone levels, and hypothalamic gene expression in laying hens. Results showed that incubation lighting had an impact on hatching performance, feather pecking behavior, and hypothalamic gene expression, indicating a potential modulation of pecking tendencies in laying hens through changes in gene expression related to serotonin system and stress. However, there were no significant effects on gentle, severe, and aggressive pecking behaviors.

Summary: In livestock breeding, continuous and objective monitoring of animals is challenging. Computer vision technology, specifically a double-camera system with image registration algorithms, can overcome the issues caused by occlusion and changes in appearance features. This approach uses a deformable learning-based registration framework with pre-registration and convolutional neural networks to improve registration accuracy. The proposed method shows significant improvement over commonly used feature-based and intensity-based methods and reduces registration time to less than 0.5 seconds.
