Association of RBP4 Genotype with Phenotypic Reproductive Traits of Sows
PCR-RFLP was applied to a commercial crossbred pig population in order to investigate the association between polymorphism (SNP) of Retinol-binding protein 4 (RBP4) gene and reproductive performance. 400 sows were genotyped and 2000 records of reproductive traits were used in order to retrieve information about the allele frequencies and the association of the RBP4 gene with main reproductive c...
متن کاملThe Effect of Diet during Lactation on the Reproductive Performance of First-litter Sows
Eighty first-litter sows in a commercial piggery were assigned to two feeding treatments during a 26-day lactation. A commercial diet containing an estimated 15% crude protein (CP), 0.65% lysine and 12.5 MJ digestible energy (DE)/kg was offered to sows in the control group which consumed 3.04 kg/day. Sows in the treatment group were given a higher quality diet containing 16.4% CP, 0.83% lysine ...
متن کاملTelomere length and reproductive aging
BACKGROUND Rate of reproductive aging may be related to rate of biological aging. Thus, indicators of aging, such as short telomere length, may be more frequent in women with a history suggestive of premature reproductive senescence. METHODS Telomere-specific quantitative PCR was used to assess telomere length in two groups of women with evidence of reproductive aging: (i) patients with idiop...
متن کاملA Novel Mutation in NLRP7 Related to Recurrent Hyda-tidiform Mole and Reproductive Failure
Objective Hydatidiform mole (HM) is an abnormal human pregnancy with excessive trophoblastic proliferation and abnormal embryonic development, which is divided into two Complete (CHM) and Partial (PHM) groups. One subcategory of the CHMs is recurrent and familial, which is known as biparental hydatidiform mole (BiHMs) or recurrent hydatidiform mole (RHM). NLRP7 and KHDC3L, two maternal-effect g...
متن کاملFluctuation of potential zinc status biomarkers throughout a reproductive cycle of primiparous and multiparous sows.
Fluctuations in Zn metabolism throughout gestation and lactation might affect Zn requirements. However, scientific data on Zn requirements for breeding sows are limited. The objective of the present study was to assess the Zn status of primiparous and multiparous sows using different Zn status biomarkers, to identify periods of critical Zn status throughout the reproductive cycle at different p...
