The aim of this study was to analyse a novel group farrowing system (GH) concerning piglets’ behaviour, skin injuries and body weight gain, to test its animal friendliness. Skin injuries and weight gain were compared to piglets originating from conventional individual housing (IH) before and after weaning. The GH system had five farrowing pens without crates, a common area and an area only available for piglets. In total, 34 litters were studied. Four days after the GH-piglets had left the pens during lactation, the lesion score of piglets in GH was higher than in IH. However, piglets from the GH sustained fewer injuries after mixing at weaning, compared to the piglets from IH and had higher daily weight gains, during the early nursery phase. The common area in GH was intensively used for active behaviour, since standing/walking and playing were observed there, most frequently, whereas lying occurred most frequently inside the pens. Immediately after the piglets had left the pens in the GH, the piglets preferred proximity to the sow, compared to the pens where they were born. The GH system enabled social enrichment, offered increased space for activity and led to fewer skin lesions, after weaning; thus, potentially increasing animal welfare.

AbstractIndividual housing from weaning onwards resulted in reduced growth rate during adolescence in male C57Bl/6J mice that were housed individually, while energy intake and energy expenditure were increased compared to socially housed counterparts. At 6 weeks of age, these mice had reduced lean body mass, but significantly higher white adipose tissue mass compared to socially housed mice. Body weight gain of individually housed animals exceeded that of socially housed mice during adulthood, with elevations in both energy intake and expenditure. At 18 weeks of age, individually housed mice showed higher adiposity and higher mRNA expression of UCP-1 in inguinal white adipose tissue. Exposure to an obesogenic diet starting at 6 weeks of age further amplified body weight gain and adipose tissue deposition. This study shows that post-weaning individual housing of male mice results in impaired adolescent growth and higher susceptibility to obesity in adulthood. Mice are widely used to study obesity and cardiometabolic comorbidities. For (metabolic) research models using mice, (social) housing practices should be carefully considered and regarded as a potential confounder due to their modulating effect on metabolic health outcomes.

Abstract Background: Avian coccidiosis is a major disease within the poultry industry caused by species of Eimeria, an intestinal protozoan parasite. Body weight gain, intestinal lesion score, and fecal oocyst shedding are parameters that have been used to assess the protective effects of various treatments in Eimeria-infected chickens. The objective of this study was to compare the aforementioned parameters in broiler chickens infected with major parasitic species of Eimeria, such as E. acervulina, E. maxima and E. tenella. Results: The results of the body weight gain, intestinal lesion score, and fecal oocyst shedding showed similar patterns between female and male broilers infected with Eimeria species. However, there was a difference in body weight gain between normal females and males, and also between Eimeria-infected females and males. When broilers were infected with 1×104 sporulated oocysts of Eimeria species, each Eimeria species induced distinct changes in body weight gain, lesion score, and fecal oocyst shedding. In addition, a lesion score of approximately 3 was more closely related to body weight gain than a lesion score of approximately 2. Conclusion: These results suggest that certain levels of lesion severity are more closely related to body weight gain.

Eimeria tenella (E. tenella) is a highly pathogenic and prevalent species of Eimeria that infects chickens, and it causes a considerable disease burden worldwide. The secreted proteins and surface antigens of E. tenella at the sporozoite stage play an essential role in the host–parasite interaction, which involves attachment and invasion, and these interactions are considered vaccine candidates based on the strategy of cutting off the invasion pathway to interrupt infection. We selected two highly expressed surface antigens (SAGs; Et-SAG13 and Et-SAG) and two highly expressed secreted antigens (rhoptry kinases Eten5-A, Et-ROPK-Eten5-A and dense granule 12, Et-GRA12) at the sporozoite stage. Et-ROPK-Eten5-A and Et-GRA12 were two unexplored proteins. Et-ROPK-Eten5-A was an E. tenella-specific rhoptry (ROP) protein and distributed in the apical pole of sporozoites and merozoites. Et-GRA12 was scattered in granular form at the sporozoite stage. To evaluate the potential of rEt-ROPK-Eten5-A, rEt-GRA12, rEt-SAG13 and rEt-SAG proteins as a coccidiosis vaccine, the protective efficacy was examined based on survival rate, lesion score, body weight gain, relative body weight gain and oocyst output. The survival rate was significantly improved in rEt-ROPK-Eten5-A (100%) and rEt-GRA12 (100%) immune chickens compared to the challenged control group (40%). The average body weight gains of rEt-ROPK-Eten5-A, rEt-GRA12, rEt-SAG13 and rEt-SAG immunized chickens were significantly higher than those of unimmunized chickens. The mean lesion score and oocyst output of the rEt-ROPK-Eten5-A immunized chickens were significantly reduced compared to unimmunized challenged chickens. These results suggest that the rEt-ROPK-Eten5-A protein effectively triggered protection against E. tenella in chickens and provides a useful foundation for future work developing anticoccidial vaccines.

Abstract Toll-like receptor (TLR) agonists are emerging as promising vaccine adjuvants and immunomodulators in poultry against many diseases. Infectious bursa disease (IBD) still remains as a major threat in poultry industry. Improving the vaccine mediated immune response would help in better protection against IBD virus infection. Adjuvant potential of TLR3 agonist, Poly I:C with different IBD vaccines has been analyzed in chicken in the present study. Intermediate, intermediate plus IBD vaccine, bursaplex vaccine and their respective poly I:C combinations were used for immunization of chicken. IBD specific antibody titre, bursa to body weight ratio, body weight gain and bursal lesion scores were evaluated at weekly interval in different immunization groups. Fold changes in cytokines IL-1β and IFN-γ mRNA expression levels were also analyzed in different groups. Intermediate IBD plus vaccine induced significantly (P≤0.05) higher IBD specific antibody response at 35 days of age than other groups with comparatively lower body weight gain and moderate bursal lesion score. Poly I:C co-administration with intermediate IBD vaccine and bursaplex vaccine improved the IBD specific antibody titres, better body weight gain and moderately less bursal lesion score. However, Poly I:C combination with intermediate plus IBD vaccine did not improve the specific immune response. IL-1β levels were up-regulated in intermediate plus and bursaplex group, whereas IFN-γ m RNA expression levels were upregulated in intermediate IBD with Poly IC group. In conclusion, poly I:C co-administration with intermediate IBD and bursaplex vaccine was beneficial and improved the specific immune response with least immunosuppression and bursal damage.

The Unfolded Protein Response

ABSTRACT The unfolded protein response (UPR) is involved in the pathogenesis of metabolic disorders, yet whether variations in the UPR among individuals influence the propensity for metabolic disease remains unexplored. Using outbred deer mice as a model, we show that the intensity of UPR in fibroblasts isolated early in life predicts the extent of body weight gain after high-fat diet (HFD) administration. Contrary to those with intense UPR, animals with moderate UPR in fibroblasts and therefore displaying compromised stress resolution did not gain body weight but developed inflammation, especially in the skin, after HFD administration. Fibroblasts emerged as potent modifiers of this differential responsiveness to HFD, as indicated by the comparison of the UPR profiles of fibroblasts responding to fatty acids in vitro, by correlation analyses between UPR and proinflammatory cytokine-associated transcriptomes, and by BiP (also known as HSPA5) immunolocalization in skin lesions from animals receiving HFD. These results suggest that the UPR operates as a modifier of an individual's propensity for body weight gain in a manner that, at least in part, involves the regulation of an inflammatory response by skin fibroblasts.

Background and Objective: Yoghurt, especially bio-yoghurt has long been recognized as a product with many health benefits for consumers. Also, honey and olive oil have considerable nutritional and health effects. So, the effect of administration of yoghurt made using ABT culture and fortified with honey (2 and 6%), olive oil (1 and 4%) or honey + olive oil (2+1 and 6+4% respectively) on some biological and hematological properties of rats was investigated.Methods:The body weight gain, serum lipid level, blood glucose level, serum creatinine level, Glutamic Oxaloacetic Transaminase (GOT) activity, Glutamic Pyruvic Transaminase (GPT) activity, leukocytes and lymphocytes counts of rats were evaluated.Results:Blending of bio-yoghurt with rats' diet improved body weight gain. Concentrations of Total plasma Cholesterol (TC), High-Density Lipoprotein cholesterol (HDL), Low-Density Lipoprotein cholesterol (LDL), Very Low-Density Lipoprotein cholesterol (VLDL) and Triglycerides (TG) significantly lowered in plasma of rats fed bio-yoghurt. Levels of TC, LDL, VLDL, and TG also decreased in rat groups feed bio-yoghurt supplemented with honey and olive oil. LDL concentrations were reduced by 10.32, 18.51, 34.17, 22.48, 43.30% in plasma of rats fed classic starter yoghurt, ABT yoghurt, ABT yoghurt contained 6% honey, ABT yoghurt contained 4% olive oil and ABT yoghurt contained 6% honey + 4% olive oil respectively. The blood glucose, serum creatinine, GOT and GPT values of rats decreased while white blood cells and lymphocytes counts increased by feeding bioyoghurt contained honey and olive oil.Conclusion:The findings enhanced the multiple therapeutic effects of bio-yoghurt supplemented with honey and olive oil.
