The novelty of current work represented in examining the lytic activity of four phages and their combination compared to the antibiotic streptomycin on Pseudomonas aeruginosa-infected Nile tilapia (Oreochromis niloticus) while measuring the hematological and blood biochemical parameters as a response for phage therapy. This study evaluated the in vitro killing curve for each phage using a growth curve that measured the OD600 after a single phage suspension was combined with the host P. aeruginosa, considered the best multiplicity of infection (MOI) for each phage. A144 healthy fish were acclimatized in the laboratory and divided into six groups: control, P. aeruginosa-infected fish, streptomycin, phage Ps1, Ps2, both (Ps1 and Ps2), were added to the T3, T4, T5, and T6 groups, respectively. Our findings demonstrated that P. aeruginosa infection caused surface body hemorrhages, tail and fin rot, irritated skin, superficial ulcers, and 100% mortality through 14 days. P. aeruginosa caused a reduction in hemoglobin (Hb), red blood cells (RBCs), platelet number (PLt), and platelet crit (PCT) count protein, albumin, and A/G ratio; however, an increase in hematocrit (Hct); Red cell distribution width (RDW), PDW, MPV compared to other groups after three days of infection and the effects increased after 12 days post-infection. The fish vaccinated with P1 (T4) and P1+P2 (T6) showed enhanced levels of Hb, RBCs, PLt, PCt, protein, albumin and decreased levels of RDW, PDW, MPV, and liver and kidney enzymes with enhanced contents more than streptomycin and closer to the control group. The biochemical markers recorded significant changes indicating liver and kidney impairments due to the infection with P. aeruginosa. It can concluded that P1 and P1+P2 combinations could use as therapy in Pseudomonas-infectd fish to enhance their blood parameters and performance.","PeriodicalId":48859,"journal":{"name":"Annals of Animal Science","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138596260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 60 clinically healthy growing rabbits (5-weeks old) reared during summer season were divided randomly into three experimental groups, 20 rabbits each, and received 0, 2, and 4 g GC /kg diet, (GC0, GC2, and GC4), respectively. Growth performance (live body weight, LBW and average daily gain, ADG) and feed utilization (feed conversion ratio, FCR) as well as the dressing percentage and the relative weight of liver were improved significantly in the GC-treated groups compared to the control group. The dose-response regression analysis showed that the optimal doses were 2.75 and 3g GC/kg diet for ADG and FCR, respectively. Moreover, GC treatments significantly decreased both of rectum temperature and respiration rate compared to GC0, with an optimal dose being at 2.5g GC /kg diet. Erythrocytes and leukocyte counts improved significantly in the GC-treated groups compared to the GC0 group. Blood protein and its fractions, liver and kidney functions, and lipid profile were quadratically improved by GC supplementation. The optimal dose was 3g GC/kg diet for total protein and its fractions, ALT, and TG, while it was 2.5 and 2.75 g GC/kg diets for creatinine and TC, respectively. Total antioxidant capacity, superoxide dismutase, and glutathione activities were significantly higher, while the levels of malondialdehyde were significantly lower in the GC-treated groups than the GC0 group. A level of 2.5g GC/kg diet was the optimal dose required for improving immunoglobulin A and G. improved in blood serum of GC treated groups compared to the control. Economically, dietary addition of GC enhanced the economic efficiency of the supplemented diets, thereby improving the profitability of the fattening process. In conclusion, dietary supplementation of GC at level of 2.5-3g/kg diet could be effectively used to enhance the growth indices, redox status, immune function, and economic efficiency of rabbits fattened during the summer season.","PeriodicalId":48859,"journal":{"name":"Annals of Animal Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135513183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To assess the inbreeding values of Holstein cattle, the ROH-based genomic inbreeding coefficient (F ROH ) was calculated. The comparison of SNP panels suggested that F ROH values above 4 Mb should be considered for panels of medium densities as a relatively reliable measure of inbreeding. Moreover, ROH hotspots and coldspots were identified and compared between the HD and 50k SNP panels and were carefully examined for association with production and functional traits. The obtained results pinpointed genomic regions presumably under selection pressure in Holstein cattle. The regions overlapped with a large number of genes, including GHR, GBF1, SUMF1, CCL28, NIM1K, U6, BTRC and FABP1 , many of which are involved in important Holstein cattle characteristics. We also found that some ROH hotspots and coldspots identified with the HD panel were not detected with the 50k panel, mainly because of insufficient SNP density in certain genomic regions. This suggests that using medium-density panels might not be the best choice when precise identification of ROH patterns is the main goal. In summary, in this work, we confirmed that a high-density SNP panel compared to a medium-density SNP panel allows for more precise identification of ROH patterns, especially in the case of short ROH that could be associated with ancestral inbreeding.","PeriodicalId":48859,"journal":{"name":"Annals of Animal Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135513184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At a time when this sector is growing, sheep are exposed to various challenges. These include climate change, which can cause heat stress in sheep, including rams, which later negatively affects their growth and reproductive performance. Exposure to heat stress results in physiological and reproductive behaviour responses in rams, which could also be used to visually identify the effect of heat stress as it will affect the productivity of livestock. In addition, the year-round hot and humid climate of the tropics is expected to contribute to a higher probability of heat stress occurrences in rams reared in developing countries around the equator. Nevertheless, the adaptability of rams to heat stress varies according to their origin, whereby native breeds tend to adapt better. Despite that, native breeds still can be affected by adverse environmental conditions and rely on thermoregulation mechanisms to mitigate heat stress. This results in numerous negative physiological changes, such as sweating and increased heart rate. This review highlights the effects of heat stress on the physiology, reproductive behaviour and reproductive performance of male sheep.

The use of PAR was associated with acute kidney injury and other side effects, and its hazardous effects were influenced by oxidative stress and inflammation. Black seed oil's primary active ingredient, thymoquinone (TQ), has anti-inflammatory, immunomodulatory, and antioxidant properties. A few animal models for drug-induced nephrotoxicity described promising outcomes of its renoprotective action. The main goal of this work was to evaluate TQ nanoparticles' (TQNP) powerful renoprotective properties in a rat model of nephrotoxicity caused by PAR. Three groups of eight rats each were assigned; group one (the control group, CON) was given gavaged normal saline. Group 2 (PAR group, PAR) received 600 mg/kg of gavaged PAR diluted in regular saline. One hour after PAR delivery, group 3 (the TQNP group) received TQNP 0.5 mg/kg via oral administration. In rat kidney tissues, PAR resulted in renal damage, a rise in blood urea nitrogen (BUN), creatinine, cystatin C (CYC), myeloperoxidase, protein carbonyl (PC), malondialdehyde (MDA), and a decrease in nitric oxide and cellular antioxidants. In rats given PAR, TQNP effectively reduced renal damage, lowered serum levels of creatinine, BUN, and CYC, and improved oxidative stress (MDA, MYO, and PC) and inflammatory markers (TNFα and IFN-γ). TQNP treatment resulted in modestly dilated/congested blood vessels in the renal tissues of PAR. The TQNP's reno-protective action is an effective preventative against PAR-induced nephrotoxicity, primarily by enhancing cellular defense mechanisms and reducing inflammatory and oxidative indicators in a rat model. However, additional research and clinical trials should be needed for testing in future studies.","PeriodicalId":48859,"journal":{"name":"Annals of Animal Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135513185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By manipulating various physiological, immunological, and behavioral activities, altering the color of light has been acknowledged as a potent managerial strategy capable of mitigating an array of stressors in broiler chickens. Assessing animal welfare is necessary for animal behavior and product quality perspectives. Birds have a unique visual system, and their behavior is primarily mediated by vision. Different monochromatic light regimes can affect feed conversion ratio, modulating broiler chickens’ systematic immune response and aggressive behaviour.

A total of 315 Nile tilapia fingerlings (4.11± 0.12 g/fish) were divided into seven treatments in triplicate. The fish were stocked in glass aquaria (50 × 40 × 30 cm; 60 L each) at a rate of 15 fish per aquaria. Experimental diets contained BSFM at increasing levels of 0, 5, 10, 15, 20, 25, and 30% as FM replacers were offered twice daily to apparent satiation for 84 days. The results revealed that BSFM replacements significantly (p = 0.001) enhance water quality and reduce the total ammonia, NH3, and NO2 levels compared to the control. The growth performance, feed conversion ratio, and survival were improved with increasing BSFM meal inclusion levels up to 25% (p = 0.001, 0.017, and 0.001 respectively). However, the zootechnical performance of the experimental fish started to decline with increasing replacement levels to 30%. Also, by an increase in BSFM level to 25%, hematobiochemical markers were considerably (p ≤ 0.01) enhanced. The liver and kidney function indicators improved (p = 0.001) with dietary BSFM. The economic evaluation revealed that feed costs and fish weight gain were decreased by increasing BSFM levels in fish diets. The current study highlighted the potential environmentally beneficial use of BSFM as an FM replacer in terms of reducing water nitrogen waste levels and improving growth performance, health status, and enhancing the economic feasibility of the commercial tilapia diet.","PeriodicalId":48859,"journal":{"name":"Annals of Animal Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134975458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
