Ten Nellore heifers were used in a two-period crossover design and fed with two diets of divergent maize silage to concentrate ratios (90:10 and 50:50). The urinary marker concentrations were strongly and positively associated with each other, and both correlated strongly and negatively with total urine volume. Creatinine excretion and chromium recovery did not vary according to diets, but chromium recovery exhibited a lower variance among animals. The evaluation of urine spot samples showed that sampling time affects both markers, with the lowest urinary concentrations obtained when samples were taken early in the morning. Both creatinine and the Cr-EDTA complex produce similar estimates of urine volume. However, despite the greater precision of the estimates obtained with chromium, the values obtained with creatinine exhibited less bias and are, therefore, more accurate.","PeriodicalId":35885,"journal":{"name":"Acta Agriculturae Scandinavica Section A-Animal Science","volume":"60 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80268628","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}

The CP ranged from 51.41 to 156.09 g/kg DM, which was especially high within M. sativa and low in H. vulgare. O. ficus indica had the highest values in free condensed tannins. The most digestible plant sample was that from M. sativa and O.ficus indica. The maximum in vitro gas production was recorded with M. sativa and H. vulgare. The same trend was observed with the total gas production (144 h).

The basal diet (C) was substituted with 3% (T1), 6% (T2) and 9% (T3) FCBD, and pigs were fed the experimental diet for 45 days. Feed efficiency was higher (P < 0.05) in T1 and T3 than in C. Quality grade was higher (P < 0.05) in T2 and T3 than in C, and the ratio of high-quality grades was higher in treatment groups than in C. Therefore, FCBD supplementation improved quality grade in fattening pigs, and it was expected that an increase in the utilization ratio of FCBD would reduce the cost of animal production.","PeriodicalId":35885,"journal":{"name":"Acta Agriculturae Scandinavica Section A-Animal Science","volume":"34 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85066995","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}

The genetic parameters of the elk hunting traits were estimated using a repeatability animal model. Season, place, and type of the trial, weather during the trial, and dog sex and age were considered fixed effects in the models, and trial judge and dog litter were treated as random effects. Variance components were estimated with the AI-REML method using the DMU-software. Heritability estimates were generally low (0.01–0.04). The highest estimated heritability was 0.04 for searching. Repeatability estimates for elk hunting traits varied between 0.04 and 0.14. Genetic correlations varied from very weak to very strong (−0.21–1.00) and were particularly strong between the barking traits.","PeriodicalId":35885,"journal":{"name":"Acta Agriculturae Scandinavica Section A-Animal Science","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79995422","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}

Feed conversion ratio was the ratio of feed consumed to weight gained by the birds. Results revealed significant differences among the genotypes in those traits. Sasso outperformed all other genotypes throughout the study period. Reciprocal crosses of Fayoumi and Sasso performed better than the remaining seven genotypes, with Koekoek and reciprocals of Fayoumi and Koekoek showing intermediate performance, but Fayoumi and White Leghorn and reciprocals involving them performed the least. In most instances, reciprocals of Fayoumi with Koekoek and White Leghorn outperformed both of their parents.
