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). In conclusion, the results showed that the integration of RP-ML in ewes could be a valid strategy in order to improve their performances but further investigations are necessary to define the right concentration to be administered to the animals.","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":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11625658/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142794254","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 hair cortisol of the back region (white color) was higher than the other region and color (p < 0.05). The measured value in the spring season (back region) was significantly higher than that in the summer (chest region) (p < 0.05). Although there has been no report on the hair aldosterone until now, it was possible to measure the concentration in the present study. The hair aldosterone of the back region was higher than the chest region (p < 0.01), and the white hair color was higher than the black hair color (p < 0.05). The measured value in the spring season was also significantly higher than that in the summer season and the winter season (p < 0.01).

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}

This study aimed to reveal the relationship between CL and 1DF positioning, pregnancy outcomes, and blood steroid hormone levels following artificial insemination (AI) in Holstein cattle. Data from heifers (n = 163) and cows (n = 69) with optimally timed AI, defined as ovulation within 24 h post-AI, were analyzed to determine associations between CL (left/right ovary) and 1DF (ipsilateral/contralateral to CL) locations and conception rates. Plasma progesterone (P4) and estradiol-17β (E2) concentrations were measured five days post-insemination. In heifers, neither CL (p = 0.24) nor 1DF location (p = 0.44) affected conception rates. Cows with left-sided CL tended to have higher conception rates than those with right-sided CL (p = 0.08). Relative 1DF location did not affect conception in cows. The location of CL and 1DF did not affect plasma P4 and E2 concentrations or the ratio of plasma E2 to P4 in heifers or cows. These findings suggest a trend towards improved conception rates in cows with CL located on the left ovary post-AI, regardless of 1DF location. The mechanism should not be associated with systemic ovarian hormones.","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":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142779383","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}

Therefore, the pigs are required to have as low a PERV copy number as possible. In this study, firstly, we investigated the estimates of heritabilities for the PERV copy numbers in the Vietnamese native breeds. Genomic heritabilities for four genes on PERV were estimated using the restricted maximum likelihood method with the genomic relationship matrix. The genomic heritability estimates of these genes ranged from 0.27 to 0.71, indicating that it would be possible for these genes not to follow the normal Mendelian inheritance. Secondly, we bred the pig population to reduce the pol gene number and estimated the heritability for the number. Despite the high heritability estimate for the pol gene (0.59), little improvement was progressed after selection for reducing the gene number in the three generations. In order to reduce the PERV copy numbers from the pig genome, it would be difficult to adapt only conventional breeding technology, and we need to consider using another technology like genome editing.","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"95 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142674163","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}

Our findings suggest that education status, adult cattle unit, animal breed type, off-farm income activities, farm size, and access to training and market significantly influence adoption of improved forage technologies and practices. Further, the adoption led to a significant increase in daily milk yield (1.07 to 1.34 L), total dry matter availability by over 27%, and green fodder availability by around 80%.
