Sixty piglets, 30 ±3 days old with initial bodyweight of 8.41±0.92 kg, were allotted randomly to six pens of ten piglets. There were two replicates of each treatment, namely a control diet (C), a diet supplemented with 1% Bs (E1), and a diet supplemented with 3% Bs (E2). Feed was provided ad libitum as flour in two meals per day. Feed materials were examined for total numbers of fungi, aerobic mesophilic bacteria (TNG), Coliforms, Escherichia coli and Salmonella spp. The addition of Bs did not influence (P >0.05) bodyweight (BW) or average daily weight gain (ADWG). However, across the experimental period ADWG was greater in E2 and E1 than in C (>1.12 and 1.08 times compared with C). Feed intake (ADFI) by pigs fed C was greater than pigs fed E1 and E2. Feed efficiency was higher in E1 and E2 than the C diet. Addition of 1% Bs decreased (P<0.05) diarrhoea occurrence around 8% compared with C, and 4% compared with 3% Bs. A total of 23.4% of the piglets produced soft faeces. Diarrhoea scores of 2 (mild diarrhoea) and 3 (severe diarrhoea) were observed in 43.75% and 32.81% of the pigs. No differences (P >0.05) were detected between the treatments. The results suggested that E1 could positively affect growth performance and mitigate the occurrence of diarrhoea.","PeriodicalId":21869,"journal":{"name":"South African Journal of Animal Science","volume":"30 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72978078","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}

There were four replicates of four treatments, with each replicate including ten male Ross 308 broiler chickens. The experiment was conducted over a 42-day period. The treatments consisted of two levels of L-Carnitine (200 and 400 mg/kg) and two levels of fenofibrate (50 and 100 mg/kg) as supplements to a basal diet. Growth, carcass characteristics, serum constituents, immune system responsiveness, cecal microflora, sensory attributes and fatty acid profiles of breast meat, and small intestine histology were characterized. During the finishing period, the chickens fed a diet containing 400 mg/kg L-Carnitine and 50 or 100 mg/kg fenofibrate had lower feed intake andfeed conversion ratio (FCR) and higher weight than the other treatments. Application of 400 mg/kg L-Carnitine in combination with two levels of fenofibrate reduced ventricular fat (P <0.05), cholesterol (P <0.01), triglycerides (P <0.05), and very low density lipoprotein (VLDL) (P <0.05). These treatments increased antibody titers against Newcastle disease (ND)and avian influenza virus (AIV). Among the sensory properties of breast meat, experimental treatments had a significant effect only on its aroma (P <0.05). In general, supplementing the diet of Ross 308 broilers with 400 mg/kg L-Carnitine and 50 or 100 mg/kg of fenofibrate is recommended.","PeriodicalId":21869,"journal":{"name":"South African Journal of Animal Science","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83639723","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}

Birds fed on 1500 ppm NSO diet showed the heaviest body weight at 14, 28 and 42 days of age. Feed conversion ratio was significantly improved at all ages with the inclusions of OTC and NSO generally superior to the control group. The relative weight of spleen was increased significantly by the addition of NSO at various levels. However, relative weights of thymus and bursa were not altered by the treatments. Total bacterial count, total yeast and moulds count, E. coli and salmonella spp. counts were reduced significantly, whereas the total lactic acid bacteria count was increased in OTC and NSO groups compared with control. Nigella sativa oil could be used in broiler chicken feeds as a natural alternative to antibiotic growth promoters to improve gut health and consequently growth performance.","PeriodicalId":21869,"journal":{"name":"South African Journal of Animal Science","volume":"28 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84225215","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}

Effects of HSD and RJ supplementation on growth performance, antioxidant gene expression, and intestinal antioxidant capacity in zebrafish were investigated. A total of 240 four-month-old zebrafish were used in a 2 x 2 factorial design, with four treatments and three replications. The treatments consisted of normal stocking density (NSD) (1 fish/L) and high stocking density (HSD) (3 fish/L) and an unsupplemented commercial diet (0RJ) and commercial diet supplemented with 10% RJ (10RJ). The experiment lasted 25 days. Daily weight gain, final body length, specific growth rate, and survival were recorded. On day 25, six fish per treatment were euthanised and their intestines analysed for antioxidant capacity, and superoxide dismutase 2 (SOD2) and catalase (CAT) gene expression. There were no effects of diet or SD and diet interaction on growth. High stocking density decreased daily weight gain by 25.31%, body length by 2.70%, and survival by 16.85%. Stocking density (SD) and diet interaction influenced intestinal SOD2 and CAT expression and antioxidant capacity. The HSD/0RJ group had lower antioxidant gene expression and antioxidant capacity than the HSD/10RJ and NSD/0RJ groups. Supplementation with RJ did not mitigate the harmful effects of stocking stress. These results indicate that HSD promotes transcriptional suppression of gene encoding enzymes that form the first line of antioxidant defence, resulting in reduced elimination of toxic substances and occurrence of intestinal oxidative stress.","PeriodicalId":21869,"journal":{"name":"South African Journal of Animal Science","volume":"15 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85244040","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 31 095 cattle skins were randomly selected between 15 November 2020 and 15 March 2021 and examined. The prevalence of warbles was 47.3%. The proportions of cattle with warbles on the skin on their backs were 76.6% in one-year-old and younger animals, 60.9% in two- and three-year-old animals, and 16.5% in cattle that were four years old or more. It was determined that 53.6% of the cattle with warbles on the back skin were indigenous breeds, 47.6% were Simmental and Montofon crosses, and 36.2% were domestic breeds. The average number of larvae was 8.2. Interviews with the owners of the infected animals revealed that hide loss was on average 10% in live weight, with a 5% to 8% in the milk production of dairy cows. In the animals under investigation the total economic loss from warbles caused by damage to the hide was calculated as US$114 188.

The muscles were collected from carcasses of 12 healthy 18- to 22-month-old Holstein steers that had been subjected to similar care and nutrition programmes. A replicated 4 x 4 Latin square design was used to compare the effects of the treatments of blade tenderization, enzymatic tenderization, marination and control. Blade tenderization and enzymatic tenderization had statistically similar colour values to the control, whereas marination had negative effects on the colour of raw and cooked samples. Blade tenderization had the lowest mean Warner-Bratzler shear force value (37.88 N), whereas enzymatic tenderization had the second lowest value (42.87 N). In sensory evaluation, significant differences were observed when the samples cooked to an internal temperature of 82 °C. A simple ranking test indicated that the most preferred sample was obtained with the blade tenderization. Also, blade tenderization and then enzymatic tenderization had the highest scores for tenderness in sensory evaluation. Although Holstein cattle are known for superior milk production and may not be a suitable breed for high-quality meat production, the results indicated that blade tenderization and enzymatic tenderization could be used to improve the tenderness of TrA steaks from Holstein carcasses and use them better.","PeriodicalId":21869,"journal":{"name":"South African Journal of Animal Science","volume":"19 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79449479","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}

High throughput SNP genotyping and next-generation sequencing (NGS) have made it possible to study positive selection footprints and adaptation traits. Nguni is a small frame-size breed, mostly horned, and well known for being adapted to diverse South African environmental conditions. This study used previously identified selective sweeps to perform functional analysis of genes related to phenotypic characteristics in Nguni. Two hundred and sixty-four candidate selective sweeps were used for gene-set enrichment analysis in molecular functional categories (KEGG pathways) using the database for annotation, visualization, and integrated discovery (DAVID). In total, 107 genes were identified across all the chromosomes with 74 genes associated with eight phenotype queries, including fat content, milk production, walking ability, heat tolerance, meat production, reproduction, and bone and muscle development. Gene CRHR2 was associated with meat quality (juiciness and flavour). The IRAK3 gene was associated with decreased body size, feed intake and fatness in cattle, and CARD15 with disease resistance. Gene annotation using phenotype queries identified four genes (SPI, YWHAZ, RGS4, and RGS5) that were associated with myometrial relaxation in cattle. Genes such as NOD2 and IL21R were associated with inflammatory bowel diseases in cattle, whereas CPLS gene was associated with fat content. These genes are important to the phenotypic and adaptive characteristics present in South African Nguni cattle and hold potential for selection for traits of economic importance.","PeriodicalId":21869,"journal":{"name":"South African Journal of Animal Science","volume":"76 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83871634","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}
