Therefore, cooking or processing venison requires careful consideration of WHC at different pH levels. While this requires nondestructively measuring the pH of venison during distribution, there are no established methods to nondestructively distinguish between normal- and high-pH meats. We investigated the relationship between the pH of venison and impedance measured with touch-type electrodes. Significant negative correlations were found between pH before and after storage and drip loss (p < 0.05) and between impedance before storage using touch-type electrodes measured at 10 kHz and pH after 24 h of storage (p < 0.01). These results provided an estimating equation (y = −0.10x + 10.84) that can be used to nondestructively determine the pH of venison (y) after 24 h of storage by measuring its impedance (x) before storage using touch-type electrodes measured at 10 kHz (p < 0.01). Therefore, this study suggests the possibility of nondestructively estimating venison pH by measuring impedance using touch-type electrodes.","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"96 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11707497/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142942846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The volatile compounds of airag were investigated by the GC–MS method. A total of 95 kinds of volatile compounds were detected, and these were classified into 6 different classes: 14 acids, 14 alcohols, 16 aldehydes, 19 esters, 9 ketones, and 23 aliphatic hydrocarbons. Among them, acetic acid, 2-methyl propionic acid, isoamyl lactic acid, 2-methyl butanoic acid, hexanoic acid, heptanoic acid, octanoic acid, nonanoic acid, n-decanoic acid, 1-propanol, 3-methyl 1-butanol, phenyl ethyl alcohol, acetaldehyde, acetoin, ethyl acetate, ethyl hexanoate, ethyl caprylate, ethyl decanoate, ethyl 9-decanoate, and ethyl laurate had a high concentration in airag samples. It may explain that acids, alcohols, and esters mainly influence the taste and aroma of airag, and aldehydes change depending on their fermentation time. We also found that Bulgan provinces` samples contained 20 types of aliphatic hydrocarbons, which may relate to the vegetation and fermentation process. The formation of sensory characteristics in airag is a complex and unclear process because it affects many factors. Our findings provide essential guidance on the composition of volatile compounds in Mongol airag.","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"96 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142930721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, 13 colonies of 6 different breeds raised in 10-frame Langstroth hives were used. The effects of independent variables were predicted using data mining algorithms and 15 performance metrics for the effectiveness of the algorithms. Colony power (CP), thermal temperatures (Tmin, Tmax, and Tmean), breed, a*, b*, red, green, saturation, and brightness impacted HY and BWY in different algorithms, but not birth year of queen, L, hue and blue. As a result, XGBoost, CART, and RF demonstrated high predictive performance, respectively. Due to their higher predictive performance, XGBoost and CART algorithms could predict HY and BWY using CP, thermal temperatures, and image values. These techniques could be useful for producers to monitor production quickly and non-invasively without threatening colony welfare.","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"95 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142794271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two groups of 15 ewes with equal average body weight were considered for the trial. The control group was administered a standard diet (Control, C) and the experimental group the standard diet supplemented with 1.5% lysine and 1.0% methionine (Treated, T). Results showed that RP-ML supplementation positively influenced milk yield, fat and protein content, and casein (p < 0.01). Furthermore, lambs of the T group, compared with those of the C group, showed a 15% higher growth rate during the suckling period of 42 days. Finally, the total antioxidant capacity of milk, measured by ferric reducing antioxidant power and 2,2′-azino-bis(3-ethylbenzotiazolin-6-sulfonic acid assay, was significantly lower in T groups (p < 0.05).

These disorders are difficult to detect, diagnose, and record, causing animal health problems and serious economic losses. The coronet score is a new hoof health indicator developed by the Dairy Herd Improvement Program of Japan. This score is assigned on a 5-point scale and can easily be determined by examining the degree of redness and swelling around the hooves. To determine whether coronet scores can be used to genetically improve hoof health, we investigated non-genetic factors in the score, developed a genetic analysis model, and estimated genetic parameters. Coronet scores were collected from 1280 herds in 28 prefectures once a month from 2014 to 2021. Furthermore, 1,598,878 test-day records of 94,951 cows from the first- to third-parity and pedigree information of 216,416 individuals were used in the analysis. Results revealed that herd size, parity, age, test month, and lactation stage influenced the coronet score. Additionally, the heritability of the coronet score estimated via the herd-test-day model was 0.027, and genetic trends deteriorated in sires and cows. Overall, we demonstrated that coronet score is a heritable trait, suggesting that hoof health could be genetically improved by selection for coronet score.","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"95 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11617061/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142779464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
