Consistently, microbiome alterations are linked to digestion, immunity, and productivity. <i>Sasa quelpaertensis</i> Nakai (SQ) is a perennial bamboo species rich in proteins and fiber. Previous studies have confirmed the health benefits of SQ; however, the effects of SQ supplementation on gut microbiome and production performance are unclear. Herein, Landrace pigs were supplemented with SQ extract (SQE) and gut microbial compositions as opposed to the control group were assessed using 16S rRNA sequencing. Additionally, the influences of SQE supplementation on average daily gain (ADG) and backfat thickness (BF) were assessed after slaughter. In the SQE group, Firmicutes and Actinobacteria phyla increased significantly, whereas Bacteroidetes and Spirochaetes phyla markedly decreased (<i>p</i> < 0.05). The expression level of <i>Bifidobacterium</i> and <i>Lactobacillus</i> genera increased, whereas that of <i>Treponema</i>, <i>Prevotella</i>, and <i>Turicibacter</i> decreased (<i>p</i> < 0.05). The microbial richness was similar between groups; however, microbial diversity decreased in the SQE supplementation group. Additionally, the SQE supplementation in pigs resulted in a slight increase in ADG. In contrast, BF in the SQE group decreased notably (<i>p</i> < 0.05). These results underscore the significant influence of SQE supplementation on the gut microbiota and demonstrate the potential of SQ as a valuable feed resource for enhancing animal productivity.</p>","PeriodicalId":14923,"journal":{"name":"Journal of Animal Science and Technology","volume":"66 4","pages":"740-748"},"PeriodicalIF":2.7,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11331370/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142008867","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}

In addition, food-related diseases are exponentially increasing due to using synthetic additives in food products. Therefore, this research aimed to develop semi-dried goat meat jerky considering geriatric preferences by using natural tenderizers and nitrate. Four treatments were formulated negative control (NC [synthetic nitrite without tenderizers]), positive control (PC [Swiss chard without tenderizers]), T1 (Swiss chard with pineapple powder), and T2 (Swiss chard with pineapple and tomato powder). T1 and T2 had higher processing yield, and rehydration capacity compared with NC and PC. The fat content of T1 and T2 was lower than the control groups. Moisture was significantly higher in T1, NC, and T2 than in PC (<i>p</i> < 0.05). T2 showed the lowest water activity (0.87), lowest shear force (4.82 kgf), and lowest total plate count (TPC). The lowest pH and thiobarbituric acid reactive substances (TBARS) were observed in T1 and T2. T1 showed the lowest lightness and the maximum redness (<i>p</i> < 0.05) while PC showed the lowest yellowness. During the storage period, moisture and pH decreased, and TPC and TBARS significantly increased whereas water activity is stable regardless of the treatment. The results of the myofibrillar fragmentation index (MFI) and sodium dodecyl sulfate-polyacrylamide gel revealed that T1 and T2 more effectively converted protein to polypeptides. In addition, tenderizers positively affected thrombogenicity, atherogenicity, and hypocholesterolemic/hypercholesterolemic indices. T2 observed the highest overall sensory acceptance by reducing goaty flavor. Overall, jerky treated with tenderizers is easily chewable and digestible for the elderly due to its tenderness and essential fatty acids that would be senior-friendly food.</p>","PeriodicalId":14923,"journal":{"name":"Journal of Animal Science and Technology","volume":"66 4","pages":"807-833"},"PeriodicalIF":2.7,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11331373/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142008866","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 explore the effect of hormone supplementation during the IVM of canine immature oocytes on nuclear maturation and subsequently assess its potential application in canine somatic cell nuclear transfer (SCNT). Immature oocytes were collected and cultured in an IVM medium supplemented with hormones (follicle-stimulating hormone [FSH] and progesterone [P4]) or without hormones (control) for 24 hours. The maturation rates of oocytes in the hormone-treated group (94.92 ± 3.15%) were significantly higher than those in the control group (61.01 ± 4.23%). Both <i>in vitro</i> and <i>in vivo</i> matured oocytes underwent NT to evaluate their utility, and the fusion rates were higher in the <i>in vitro</i> matured group than those in the vivo matured group, not significant between <i>in vivo</i> and <i>in vitro</i> matured group (73.28% and 82.35%, respectively). As a result, 14 fused embryos from the <i>in vitro</i> matured group were transferred into two surrogates, with one surrogate achieving a successful pregnancy and delivering four puppies. Whereas in the <i>in vivo</i> matured group, 85 fused embryos were transferred to 8 surrogate mothers, leading to three surrogates becoming pregnant and delivering one, four, and two puppies. The pregnancy rates were not significant between both groups (50% and 37.50%), but the number of offspring exhibited a significant difference (28.57% and 8.23%). In conclusion, we achieved a remarkable milestone by successfully producing cloned puppies using <i>in vitro</i> matured oocytes, underscoring the feasibility of canine cloning from <i>in vitro</i> recovered oocytes. It is important to note that this study focused only on immature oocytes after ovulation and only during the estrus stage. Further research targeting other stages of the estrous cycle could potentially enhance canine cloning efficiency.</p>","PeriodicalId":14923,"journal":{"name":"Journal of Animal Science and Technology","volume":"66 3","pages":"577-586"},"PeriodicalIF":2.7,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11222123/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141554853","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}

Subsequently, we compared the nutrient digestibility and digestible nutrient concentrations of each energy level diet. In experiment 1, a total of 144 growing pigs with an average initial body weight (BW) of 26.69 ± 7.39 kg were randomly allotted to six dietary treatments (four pigs/pen; six replicates/treatment) according to a 2 × 3 factorial arrangement resulting from two energy systems (metabolizable energy [ME] and net energy [NE]) and three energy levels (low [LE], recommended [C], and high energy [HE]). Pigs were fed the experimental diets for 6 weeks and were allowed free access to feed and water during the experimental period. In experiment 2, 12 growing pigs with an average initial BW of 27.0 ± 1.8 kg were randomly allotted to individual metabolism crates and fed the six diets in a replicated 6 × 6 Latin square design. The six dietary treatments were identical to those used in the growth trial. Pigs were fed their respective diets at 2.5 times the estimated energy requirement for maintenance per day, and this was divided into two equal meals provided twice per day during the experimental period. Differences in energy systems and energy levels had no significant effect on the growth performance or nutrient digestibility (except acid-hydrolyzed ether extract [AEE]) of growing pigs in the current study. However, the digestible concentrations of ether extract, AEE, and acid detergent fiber (g/kg dry matter [DM]) in diets significantly increased (<i>p</i> < 0.05) with increasing energy levels. Additionally, there was a tendency (<i>p</i> = 0.09) for an increase in the digestible crude protein content (g/kg DM) as the energy content of the diet increased. Consequently, differences in energy systems and levels did not affect the BW, average daily gain, and average daily feed intake of growing pigs. This implies that a higher variation in dietary energy levels may be required to significantly affect growth performance and nutrient digestibility when considering digestible nutrient concentrations.</p>","PeriodicalId":14923,"journal":{"name":"Journal of Animal Science and Technology","volume":"66 3","pages":"514-522"},"PeriodicalIF":2.7,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11222115/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141554854","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}
