Abstract

Our objective was to develop alternatives to hormones for estrus synchronization in gilts. Gilts exhibit a pre-puberty period with high urinary estrone concentration during which boar exposure could induce the first ovulation. We searched for salivary biomarkers of this period. Urine and saliva were collected on six 140-day-old gilts until puberty for estrone assay, metabolome and steroidome analysis. We identified 23 metabolites and 28 steroids in saliva. The concentration of 8 of them showed significant variations at the pre-puberty period, they were candidate biomarkers. Saliva was collected from 30 gilts exposed to a boar and subjected to estrus detection from 150 to 175 days of age. Metabolome and steroidome analyses allowed the identification of 33 metabolites and 29 steroids in saliva. Their concentrations were not significantly different between receptive and non-receptive gilts. Thus, we could not identify salivary biomarkers of the period of receptivity to the boar effect.

Abstract

and which often tend to be obese. The SLAdd (DD) minipig line was created by the NIH and selected as homozygous at the SLA locus. It was brought to France more than 30 years ago and maintained inbred ever since. In this report, we characterized the physiological status of a herd of French DD pigs by measuring intermediate phenotypes from blood and faeces and by using Large White (LW) pigs as controls. Three datasets were produced, i.e. complete blood counts (CBCs), microarray-based blood transcriptome, and faecal microbiota obtained by 16S rRNA sequencing. CBCs and expression profiles suggested a non-alcoholic fatty liver disease (NAFLD)-related pathology associated to comorbid cardiac diseases. The characterization of 16S sequencing data was less straightforward, suggesting only a potential weak link to obesity. The integration of the datasets identified several fine-scale associations between CBCs, gene expression, and faecal microbiota composition. NAFLD is a common cause of chronic liver disease in Western countries and is linked to obesity, type 2 diabetes mellitus and cardiac pathologies. Here we show that the French DD herd is potentially affected by this syndrome.

Abstract

Estrus synchronization is important for optimal management of gilt reproduction in farms. Synthetic progestogens are used for this purpose, but there is growing demand for non-hormonal alternatives. Before puberty, gilts exhibit a “waiting period”, related to ovarian development and gonadotrophin secretions, during which external stimulation, such as boar exposure, could induce and synchronize first ovulation. Practical non-invasive tools for identification of this period in farms are lacking. During this period, urinary estrone levels are high, but urine sampling is difficult in group-housed females. Our aim was to search for steroidal biomarkers of this “waiting period” from immature to pubertal gilts through saliva monitoring. Six 144-to 147-day-old Large White gilts were subjected to ultrasound puberty diagnosis 3 times a week until first ovulation. Urine and saliva samples were collected at the same frequency for estrone assay and steroidome analysis respectively. Data were analyzed using the R software (nonparametric permutation test). Urinary estrone concentration significantly increased 2 weeks before puberty (detected at 182–192 days). Steroidome analysis quantified 28 steroids in saliva. Significant variations were detected within 2 weeks before puberty for dehydroepiandrosterone (decrease) and estradiol-17b (increase). These steroids could be biomarkers of the “waiting period”. These results confirm that non-invasive salivary sampling could allow the identification of the physiological status of the gilts and presumably the optimal time for application of the boar effect.

Abstract

National audience; Effective methods for synchronizing oestrus in gilts are crucial for implementation of batch management and optimum reproductive performances. Altrenogest treatments are used on a routine basis in pig farms, but there is growing demand for alternative non-hormonal breeding tools. Before puberty, gilts exhibit a “waiting period”, related to ovarian development and gonadotrophin secretions, during which urinary oestrone concentration increase. During this “waiting period”, an external stimulation, such as boar exposure, could induce the first ovulation. As non-invasive tools are required to increase knowledge about the “waiting period”, the aim of this work is to search for specific biomarkers of this period in urine. Trans-abdominal ultrasonographies were carried out for 5 weeks in six 140 days old Large White gilts until puberty detection (week -5 to week -1 before puberty). Urinary samples were collected for oestrone assay and metabolome analysis using 1H Nuclear Magnetic Resonance. Gilts were then slaughtered 7 days after puberty detection for puberty confirmation. Urinary oestrone concentration increases from week -2 to the day of puberty detection. Metabolome analysis allows the identification of 78 spectral bins, 8 of them showing significant differences between weeks. Metabolites whose concentration significantly increase or decrease during the “waiting period” (such as Trigonelline, N-acetyl-X…) could be interesting biomarkers of this period. These results confirm that non invasive urinary samples could make it possible to detect optimal time for application of boar effect. Potential urinary biomarkers of this period have been identified. This could contribute to decreasing the number of females mated while they are pre-pubertal.

Effective methods for synchronizing estrus in gilts are crucial for strict implementation of batch management and optimum reproductive performances. Altrenogest treatments are used on a routine basis in pig farms, but there is growing demand for alternative non‐hormonal breeding tools. Before puberty, gilts exhibit a “waiting” period, related to ovarian development and gonadotrophin secretions, during which external stimulation, such as boar exposure, could induce the first ovulation. As noninvasive tools are required to increase knowledge about the waiting period, the aim of this work is to search for specific biomarkers of this period in saliva. Trans‐abdominal ultrasonography was carried out for 5 weeks in six 140‐day old Large White gilts until puberty detection (week ‐5 to week ‐1 before puberty). We collected saliva samples as well as urinary samples for estrone assay to detect the waiting period. Gilts were then slaughtered 7 days after puberty detection for puberty confirmation. The salivary metabolome was analyzed using 1H Nuclear Magnetic Resonance. Urinary estrone assays are in progress. The concentrations of some saliva metabolites significantly increased (propionate and butyrate for example) or decreased (pyruvate and fumarate for example) between week ‐5 and week ‐1 before puberty. The identification of other metabolites whose salivary concentration significantly varied is in progress. These results suggest that some salivary metabolites could be biomarkers of the pre‐pubertal stage in gilts. Salivary monitoring may help to investigate optimal time for application of boar effect and could contribute to decreasing the number of females mated while they are pre‐pubertal.

Abstract

Three experiments were carried out to evaluate the use of ultrasonography in assessing the onset of puberty in gilts. In experiment 1, gilts (n = 17) were scanned 3 times per week beginning at 133 and continuing until 187 days of age. The ultrasonic appearance of the uterus was described, quantified and compared with the reproductive status observed at slaughter. The quantification of the pictures showed a different correlation in time for infantile, impubertal, prepubertal and pubertal stages. For pubertal females, "uterine area" increased at around 180 days of age, well-defined sections of the uterine horns appeared 3 +/- 0.5 days before puberty. In infantile and impubertal gilts during the same period of age, uterine images remained dark and homogeneous; no significant change in the "uterine area" was observed. This difference in images allowed an evaluation of the diagnosis of puberty. In experiment 2, the gilts (n = 123) were scanned, the result was verified at slaughter the day after by examination of the genital tract. The uterine weight of the gilts that had reached a prepubertal or pubertal stage was significantly greater (P = 0.0001) than that in impubertal gilts. The sensitivity and the specificity of the diagnosis were 91.9% and 96.5% respectively. Experiment 3 was performed on a farm and echographic examinations were carried out one and five days after gilts (n = 117) arrived at the piggery. Oestrus detection or blood sampling for progesterone determinations were used as tools to determine the reproductive status. The sensitivity and the specificity of the diagnosis were 98.9% and 100% respectively. This diagnosis of puberty is thus accurate.
