We weighed offspring on Days 1, 10, and 21 postnatally and collected offspring serum and gonadal samples on Day 21.Key results The results showed that 25OHD3 significantly increased maternal serum Ca2+ and Pi concentrations, and increased the growth rate and serum Ca2+ and Pi concentrations of offspring, significantly increased the serum concentrations of luteinising hormone (LH) and follicle-stimulating hormone (FSH), and accelerated the follicle development in the female offspring. Male offspring showed significantly increased LH, FSH, and testosterone serum concentrations, and 3β-HSD and 17β-HSD mRNA expressions, and a significantly decreased CYP17A1 mRNA expression.Conclusions In conclusion, the present findings indicated that maternal feeding with 25OHD3 during pregnancy positively affects offspring hormone secretion and gonadal development.Implications These insights have shed light on the potential significance of maternal nutrition in ensuring healthier animal populations and offer valuable considerations for animal husbandry practices.","PeriodicalId":7895,"journal":{"name":"Animal Production Science","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135843514","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}

{"title":"The comparison of potential key genes on rat uterus and mammary gland regulated by estradiol","authors":"Jian Zhang, Yan Cui","doi":"10.1071/an23320","DOIUrl":"https://doi.org/10.1071/an23320","url":null,"abstract":"Context Although numerous studies have investigated the regulation of estrogen (E2) on the female reproductive system, there is still a lack of understanding regarding the specific genes and pathways involved in E2 regulation of the uterus and breast.Aims The aim of this study was to explore the shared genes and pathways involved in estrogen regulation of the uterus and mammary gland, which could provide a theoretical basis for disease treatment.Methods Bioinformatics analysis was employed to identify potential genes and pathways associated with E2 regulation of the uterus and breast.Key results The analysis revealed 233 differentially expressed genes (DEGs) in datasets GSE89321 and GSE95783 (adjusted-P<0.05). Additionally, five KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways were identified: Glutathione Metabolism Pathway, Chagas Disease Pathway, Leishmaniasis Pathway, Complement and Coagulation Cascades Pathway, and p53 Signalling Pathway. A protein interaction network was constructed, and 10 hub genes (Alb, Il1a, Serpine1, Timp1, Ccl11, Fos, Krt19, Krt7, Lcn2, and C3) were selected, with Alb being the highest scoring hub gene. The study also predicted the association of Mo-mir-200a-5p and Mo-Mir-200a-3p with Alb and Krt19. Furthermore, 28 DEGs were identified in E2 regulation of the mammary gland, encompassing pathways such as Acute Myeloid Leukemia, ErbB Signalling Pathway, Th1 and Th2 Cell Differentiation, Th17 Cell Differentiation, and Transcriptional Misregulation in Cancer. Hub genes in the mammary gland included Pgr, Gata3, Areg, Prom1, Stat5a, Cldn4, Greb1, Tfap2c, Pdk4, and Mb. Prom1, Prom2, Fam84a, and Padi2 were found to be common DEGs in E2 regulation of both the uterus and mammary gland.Conclusions The findings of this study, together with functional annotation and pathway analysis, suggest that Alb serves as a marker protein in E2 regulation of uterus development. Additionally, Prom1, Prom2, Fam84a, and Padi2 are identified as common DEGs involved in E2 regulation of both the uterus and mammary gland.Implications This study provides comprehensive omics data to elucidate the mechanisms underlying estrogen regulation of the uterus and mammary gland, opening up new research directions for disease treatment.","PeriodicalId":7895,"journal":{"name":"Animal Production Science","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135559494","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}

{"title":"Sex of co-twin in utero environment does not alter reproductive fitness of Australian Merino sheep","authors":"David O. Kleemann, Simon K. Walker, Jennifer M. Kelly, Raul W. Ponzoni","doi":"10.1071/an22357","DOIUrl":"https://doi.org/10.1071/an22357","url":null,"abstract":"Context Reproductive efficiency in ewes can vary widely depending on their fertility (pregnancy rate) and fecundity (litter size) and on their ability to rear multiple litters. Litter size and sex are important factors that contribute to lamb mortality, and hence reproductive efficiency. However, little is known about their interaction when fetuses of either sex grow in utero as co-twins, nor the impact that this interaction has on subsequent performance in domestic flocks.Aims and methods We examined the effect of type of birth (single, twin) and of sex of co-twin (F, F[F], F[M], M, M[M], M[F] where the symbol within brackets indicates sex of co-twin) on birth weight, survival to weaning, weaning and hogget liveweights and scrotal circumference. In addition, reproductive performance (fertility, fecundity, lamb survival, weaning rate) of female progeny was examined as well as the performance of their lambs (birth and weaning weight). This large-scale study (>13 000 lambing observations) was conducted with Australian Merino sheep from four studs, mated over nine annual cycles.Key results Sex of co-twin had no effect on birth weight and on later stages of growth. Sex of co-twin altered survival, with fewer of the M[M] class surviving to weaning compared with other co-twin classes (P<0.05). Scrotal circumference did not vary between the male classes. Although reproductive performance (fecundity, lamb survival, weaning rate) was greater in ewes twin to a male (F[M]) than in single females (F) (P<0.05), this difference could be due to greater genetic merit of twin versus single-born progeny.Conclusions Reproductive performance of females with a male co-twin exceeded that of single females; the difference could be due to greater genetic merit of twin-born ewes rather than a direct effect of in utero environment. There was no difference between females with a male co-twin and females with a co-twin of the same sex. Reproductive capacity of males was not affected by co-twin class or type of birth.Implications These results suggest that an increase in twinning rate by managerial or genetic means will not result in undesirable side effects due to sex of co-twin in utero.","PeriodicalId":7895,"journal":{"name":"Animal Production Science","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135318850","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}

Oke","doi":"10.1071/an23183","DOIUrl":"https://doi.org/10.1071/an23183","url":null,"abstract":"Context The paradox of broiler breeders combined with harsh environments is of significant concern, particularly to broiler breeder farmers in tropical environments. Despite this, there is a paucity of information on the comparison of the performance of broiler breeders in tropical climates.Aims The trial aimed to evaluate the comparative growth and reproductive performance of three common broiler breeders (Marshall (MS), Arbor Acres (AA) and Ross (RS)) raised in the tropical environment in Nigeria.Methods In total, 240day-old female broiler breeder chicks were used, 80 each strain, in four replicates of 20 birds each. According to the breeders’ guides, the rearing of the chickens was conducted in an open-sided poultry house until puberty. Weekly determination of percentage mortality (%MORT), feed intake (FI), liveweight (LW), weight gain (WG), and feed conversion ratio (FCR) was performed. Weekly hen-day egg production was monitored in each strain from oviposition.Key results The liveweights of chickens were significantly (P<0.05) affected by strain. Ross and Marshall had higher (P<0.05) weight gain than did Arbor Acre at the first 8weeks of age. The feed intake of Arbor Acres was higher than that of Marshall, which was higher than the values recorded in Ross between the 8th and 16thweeks of age. The FCR of Arbor Acres and Ross was similar but lower (P<0.05) than that of Marshall breeders between Weeks 17 and 25. The rudimentary ovarian weights were higher in Ross than in Arbor Acres at the sixth week of age. However, at Week 20, the ovary weight was significantly (P<0.05) higher in Ross than in Marshall and Arbor Acres. Hen-day egg production of Marshall breeder was higher (P<0.05) than Ross at Weeks 24 and 25.Conclusions The three broiler breeder strains had the potential for better reproductive performance under Nigerian tropical conditions, especially the MS if the liveweight could be harnessed.Implications The findings in this study may support farmers to make the right decision on the choice of broiler breeder strains so as to maximise productivity under conventional open-sided housing in tropical environments.","PeriodicalId":7895,"journal":{"name":"Animal Production Science","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135261535","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}

Oocytes reaching Metaphase II were subjected to ICSI with immobilised spermatozoa. All ICSI oocytes were activated with calcium ionophore for 5min, followed by cycloheximide for 5h. The embryos at 6–8-cell stages were co-cultured.Key results The morula, blastocyst, and hatched blastocyst rates when co-cultured with oviductal epithelial cells were 68.18%, 48.18%, and 30.00% respectively.
