Context Studies have widely reported that a vitamin D3 metabolite 25OHD3 improves the growth performance of animals and offspring, but few studies have focused on offspring sex hormone secretion and gonadal development in the offspring.Aims This study focused on the effects of gestational feeding with 25OHD3 on the growth, serum calcium (Ca2+) and phosphorus (Pi) concentrations, and ovarian and testicular development in offspring.Methods From the beginning of gestation until the end of labour, maternal mice were gavaged daily with 25ug of 25OHD3. 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.

Context The applicability of hormones in the prediction of meat production in non-ruminant species has been poorly examined.Aims To examine the applicability of plasma concentrations of leptin, estradiol, progesterone and insulin-like growth-factor I (IGF-I) for characterisation and early prediction of the production and quality of meat in gilts.Methods Animals were compared at 150days of age with below (‘low’) and above (‘high’) median hormone concentrations and their traits of meat production and quality at the age of 200days.Key results Animals with a high leptin concentration in blood at the age of 150days had higher slaughter and carcass weights and weight of ham, but a lower lean meat content at the age of 200days, than did the gilts with a low leptin concentration. Animals with a high estradiol concentration had a higher carcass weight, weight of ham and backfat thickness and a lower electrical conductivity of musculus semimembranosus than did animals with a low estradiol concentration. High blood IGF-I concentration was associated with a higher slaughter weight, carcass weight and lean meat content. No significant differences between the animals with ‘high’ and ‘low’ progesterone concentration and meat characteristics have been found.Conclusions These observations confirm the involvement of leptin, IGF-I and estradiol in up-regulation of meat production in pigs. Furthermore, they suggest that leptin can be useful for characterisation and prediction of fat production, whereas IGF-I and estradiol (but not progesterone) could be both markers and predictors of porcine growth and meat production.Implications The blood concentrations of these hormones could help in characterisation and selection of pigs for meat production.

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.
母羊的繁殖效率取决于它们的生育力(怀孕率)和繁殖力(产仔数)以及它们养育多窝的能力。产仔数和性别是影响羔羊死亡率和繁殖效率的重要因素。然而，当任何性别的胎儿在子宫内成长为双胞胎时，它们之间的相互作用知之甚少，也不知道这种相互作用对家禽群随后的表现有什么影响。目的和方法我们研究了出生类型(单、双)和同卵双胞胎性别(F, F[F]， F[M]， M, M[M]， M[F]，括号内的符号表示同卵双胞胎性别)对出生体重、断奶存活率、断奶仔猪活重和阴囊围的影响。此外，还检测了母羊后代的生殖性能(生育力、繁殖力、羔羊存活率、断奶率)及其羔羊的生产性能(出生重和断奶重)。这项大规模研究(> 13000只羔羊观察)是用澳大利亚美利奴羊进行的，来自四个种马，交配时间为9年。主要结果:同卵双胞胎的性别对出生体重和后期生长没有影响。同卵双胞胎的性别改变了它们的存活率，与其他同卵双胞胎类别相比，M[M]类存活到断奶的数量较少(P<0.05)。阴囊周长在男性班级之间没有变化。虽然双胎母羊(F[M])的繁殖性能(繁殖力、羔羊存活率、断奶率)高于单胎母羊(F) (P<0.05)，但这种差异可能是由于双胎母羊比单胎母羊的遗传优势更大。结论同卵双生雌鼠的生殖能力优于单卵双生雌鼠;这种差异可能是由于双胞胎出生的母羊有更大的遗传优势，而不是子宫环境的直接影响。有男性双胞胎的女性和有同性双胞胎的女性之间没有差异。男性的生殖能力不受同卵双生的阶级或出生类型的影响。这些结果表明，通过管理或遗传手段增加双胞胎率不会由于子宫内同卵双胞胎的性别而导致不良副作用。

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.

Context Somatic-cell co-culture of intracytoplasmic sperm injection (ICSI) buffalo embryos has not been reported earlier.Aim This study aimed to determine the effects of buffalo oviductal epithelial-cell, granulosa-cell, and cumulus-cell co-culture on in vitro culture of early embryo development as ICSI and post-activation.Methods Selected oocyte–cumulus complexes were cultured for 19–20h in 50-μL drop of tissue culture medium (TCM199+10% buffalo follicular fluid, hCG 50IU/mL, 0.02% arbitrary units (AU)/mL follicle-stimulating hormone and 1μg/mL estradiol-17βE2). 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. The morula, blastocyst, and hatched blastocyst rates when co-cultured with cumulus cells were 51.49%, 34.33%, and 16.42% respectively. The morula, blastocyst, and hatched blastocyst rates when co-cultured with granulosa cells were 52.14%, 32.48%, and 13.68% respectively.Conclusions In vitro maturation buffalo oocytes can be fertilised in vitro with ICSI and co-cultured with different types of cells. Oviductal epithelial cell co-culture was shown to be superior in supporting in vitro embryo development in this study.Implications The oviductal epithelial cells are easy to prepare and may be used for co-culture to increase the efficiency of in vitro production of buffalo embryos.
