The experiment was undertaken for 28-days using five treatments (T); T1 = no preservative; T2 = 1.75% salt; T3 = 2.5% molasses; T4 = 2.5% Effective Microbial (EM) and T5 = 0.6% formic acid. Data was analyzed using a completely randomized two way factorial design of the mixed procedure of SAS (Version 9.1, 2001). The highest dry matter loss was for WBG stored with T1, while the lowest was for WBG treated with T5. WBG treated with T5 had the highest crude protein content, while those with T1 had the lowest. OMD of WBG treated with T5 was higher than T4. SCFA content of WBG treated with T3 was higher than those T4. WBG stored with T1 and T3 had a higher NH3N content than T4 and T5. WBG stored with T1 had the highest yeast and mold concentration, while WBG treated with T5 had the least. The highest LAB count was recorded for WBG treated with T5, while the least was for T1 and T3. Results has shown that preserving WBG with 0.6% formic acid is found to be more effective in terms of preventing spoilage by inhibiting mold and yeast growth as compared to other preservatives used in this study.","PeriodicalId":36378,"journal":{"name":"Veterinary Integrative Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41500666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The trial lasted for five subsequent 14-d periods. Treatments showed no effects on cows’ feed intake. Yeast reduced large and small particles selection indexes compared, feed residue and starch in feces compared to rbST. Cows treated with rbST had increased glucose, triglycerides, and AST, and decreased cholesterol and urea serum concentration. In addition, yeast reduced somatic cells count and increased milk yield and cows’ production efficiency. Although treatments showed no effects on milk chemical composition, yeast increased saturated to unsaturated fatty acids ratio.

The dataset included fat percentage, protein percentage, and FPR values from 160,506 records representing 23,201 first-lactation cows that calved between 1993 and 2017. These cows originated from 508 farms in all regions of Thailand. The data were analyzed using the general linear model procedure in the R program. The models included herd-year-season of records, and breed group as fixed effects, and age at calving and days in milk as covariates. The result showed that the average fat percentage, protein percentage, and FPR were 3.560±0.960, 3.130±0.390 and 1.150±0.330, respectively. Effects of herd-year-season of records, breed group, age at calving, and days in milk were highly significant for all traits (P<0.05). Cows containing less than 87.50% Holstein Friesian (HF) blood gave fat percentage, protein percentage and FPR higher than 93.75%HF and 87.50-93.74%HF. The FPR was highest in the winter and lowest in the summer. In conclusion, present results indicated that fat percentage, protein percentage and FPR are clearly influenced by both genetic and non-genetic factors. Therefore, development of different breed, feeding systems, according to season and herd is needed to produce quality of fat and protein percentage.","PeriodicalId":36378,"journal":{"name":"Veterinary Integrative Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45239838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Machine learning is being used to classify pig coughs via python. Sound files have been converted to images that are composed of wave plots,spectrograms and log power spectrograms for identification of those sounds. A recorder was used with a total of 45 healthy three-bred weaned piglets, wherein three replications of each were used with 15 weaning pigs per pen during different months. This process was set up within the housing unit at a ratio as 1:1 (recorder per pen). Sounds, blood samples and tonsil swabs were collected every month. Pig cough sounds were then classified from other sounds and a coughing index (CI) was established. Blood samples and tonsil swabs were utilized to determine respiratory diseases via laboratory tests that included ELISA, PCR and bacterial cultures. According to our results, pig coughs sound distinctly different from other sounds as had been classified by python. Moreover, the laboratory results of the seroprofile of Mycoplasma hyopneumoniae (M.hyo), Porcine Reproductive and Respiratory Syndrome virus (PRRSv), and Porcine Circovirus type 2 (PCV2), as was established by ELISA test, were employed in disease detection during the fattening period. Spearman rank correlations and Kappa analysis were used to establish correlation values between coughing and the results of laboratory tests. CI revealed a high correlation coefficient and agreement with the ELISA results of M.hyo, as well as the PCR results of PRRSv and PCV2 (p<0.05), while CI also revealed low correlation coefficient and agreement with the results of the Streptococcus spp. and Pasteurella spp. cultures (p>0.05).

However, the cryoprotective effect of sericin on re-freezing of spermatozoa has not been reported. This study was conducted to investigate the putative cryoprotective effect of sericin on re-freezing of bull spermatozoa followed by an assessment of in vitro fertilizing capacity of sericin-supplemented re-frozen spermatozoa. In experiment 1, the effect of 0.5% sericin supplemented in semen extender on re-freezing of spermatozoa was examined. Highly motile frozen-thawed spermatozoa were prepared with Percoll discontinuous gradient centrifugation prior to re-freezing. Refrozen-thawed spermatozoa were examined for motility, viability, membrane integrity, and acrosome integrity. In experiment 2, the effect of sericinsupplemented re-frozen spermatozoa on fertilizing capacity and subsequent embryonic development were determined using in vitro embryo production approach. Bovine oocytes were fertilized with three groups spermatozoa, re-frozen/control, re-frozen/sericin, and once frozen. The results showed that the total motility of re-frozen thawed spermatozoa in the sericin supplemented group was higher (53.9 % vs. 41.5%, p<0.05) than that of the control group whereas viability, membrane integrity, and acrosome integrity were unaffected. The proportion of cleaved oocytes in re-frozen/sericin-supplemented group was comparable to those in the re-frozen/control and once frozen groups. Additionally, the percentages of blastocyst development from cleaved oocytes were similar among the three groups. In conclusion, the results of this study demonstrated that pretreatment of frozen-thawed spermatozoa with 0.5% sericin improved motility after re-frozen thawed without affecting the in vitro fertilizing capacity and subsequent embryonic development.","PeriodicalId":36378,"journal":{"name":"Veterinary Integrative Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49646175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
