Abstract Acclimation can alleviate the damage caused by adverse environmental factors. To investigate effects of cold stimulation on immunity in tracheal broilers, 360 one‐day‐old chicks were raised at normal temperatures during 1–7 days. From 8 day, G1 (control) continued to be temperatures, whereas G2 and G3 (treatment groups) cold‐stimulated 3°C 12°C below temperature G1, respectively. At 42 all groups subjected a 24‐hr acute stress, designated as S1, S2, S3. Tracheal tissues collected...
Transmissible gastroenteritis virus (TGEV) infection causes acute enteritis in swine of all ages, and especially suckling piglets. Small intestinal inflammation is considered a central event the pathogenesis TGEV infections, nuclear factor-kappa B (NF-κB) key transcription factor inflammatory response. However, it unclear whether NF-κB crucial for inducing during infection. Our results show that was activated testicular (ST) cells epithelial cell lines J2 (IPEC-J2) infected with TGEV, which...
Over the past years, antibiotic growth promoter had been restricted in animal husbandry production many countries because of antimicrobial resistance and foodborne residues. However, problems poor intestinal health low efficiency piglets have not solved completely an antibiotic-free diet, it is urgent to explore alternatives promoters.Here, a total 532 weaned pigs were assigned one 4 treatments, amino acid (AA) level diet (d 1 d 14 1.35%, 15 42 1.25%) (Low AA), AA supplementation with...
An enriched environment can promote adaptability of animals to cope with complex environments. A total 18-week-old 216 laying hens were randomly divided into 2 groups; which, one group was housed in conventional battery cages (CC, n = 36), and the others furnished (FC, 180). At end 64 wk age, 24 chickens each selected for 4-hour transport treatment. The spleen tissues collected before transportation (BT), immediately after transportation, at 48 h detect expression heat shock protective...
Transmissible gastroenteritis virus (TGEV), a member of the family Coronaviridae, causes lethal watery diarrhea in piglets. Previous studies have revealed that coronaviruses develop various strategies to evade host innate immunity through inhibition nuclear factor kappa B (NF-κB) signaling pathway. However, ability TGEV inhibit immune response by modulating NF-κB pathway is not clear. In this study, dual luciferase reporter assay was used confirm infection and identify major viral proteins...
The objective of this study was to determine the effects different social ranking order (SRO) and enrichments (perch dust-bath) allocation (EA) on behavior laying hens in furnished cages.Total experimental period 4 weeks. There were 216 Hy-line brown layers beak-trimmed at 1 d age selected randomly 14 weeks from a commercial farm, divided into 36 cages with 6 each cage. High (HEA) low (LEA) provided. Video observations obtained focal between 18 perching, dust-bathing other general behaviors...
Coronavirus nonstructural protein 2 (Nsp2) is regarded as a virulence determinant and plays critical role in virus replication, innate immunity. Screening identifying host cell proteins that interact with viral an effective way to reveal the functions of proteins. In this study, interacted transmissible gastroenteritis (TGEV) Nsp2 were identified using immunoprecipitation combined LC-MS/MS. 77 putative interaction protein-protein (PPI) was constructed. The found be associated various...
Abstract Social animals form social hierarchies to maintain the relative stability of population. Individuals with high rank can, some extent, limit priority individuals lower status obtain resources, such as food, habitat and spouse. The perch behavior is instinctive laying hens. Hens have motivation choose habitat. Therefore, an effective competitive resource for objective this study was examine order small groups hens housed in furnished cages determine dominant subordinate how use...
Abstract A total 72 Lohmann white laying hens at 7 weeks old were used to evaluate the relationship between social order and perch utilization. All randomly divided into 12 cages, 6 birds in each cage. The aim of study is verify hypothesis that high-ranked chickens will use more when there are only researches (including behavior perch) all by setting up increasing length perch. Using Clutton-Brock index observing four behaviors (aggression, threat, replace chase) determine hens. data...
