摘要: Presents information on a study which determined the effectiveness of vitamin A injections in increasing litter size in sows and to determine the stages of gestation at which injections of vitamin A might increase litter size. Materials and methods; Results and discussion; Implications....
Previous studies have shown at least three waves of myogenesis occurred before day 76 of gestation in sheep [51, 52] and myofiber numbers increase sharply in a pulsed-wave mode at the second half of gestation [17]. However, their mechanisms remain unclear. In current study, significant differe...
Article: Maternal undernutrition during pregnancy and lactation affects testicular morphology, the stages of spermatogenic cycle, and the testicula
of pigs [11]. Primary myofiber formation occurs in the first wave of fiber generation, from about 35 days of gestation until around 60 days. Secondary myofibers appear at around 50–60 days based on the template of the primary myofiber surface. The third wave involves the process of ...
Failure of vitamin A to increase litter size in sows receiving injections at various stages of gestation Presents information on a study which determined the effectiveness of vitamin A injections in increasing litter size in sows and to determine the stages of gestation at which injections of vitamin...
The reciprocal Yorkshire聽脳聽Meishan F1 hybrid model and the RT-PCR/RFLP method were used to detect the imprinting status of porcine MAGEL2 gene at two developmental stages of day 30 and 65 of gestation. Imprinting analysis showed that porcine MAGEL2 was paternally expressed in day 65 fetal ...
In this work, biogas and biomethane potential of swine-derived effluents were assessed under mesophilic conditions (37 掳C) among different production stages (Farrowing, Gestation, Weaners, and Fattening) in order to investigate the suitability of anaerobic digestion as a treatment technology and ...
quantify annual emission rates (ERs) of greenhouse gases (GHGs)—methane (CH), carbon dioxide (CO) and nitrous oxide (NO) from naturally ventilated swine gestation (GE), farrowing (FA), nursery (NU) and growing-finishing (GF) barns under typical operational conditions in suburban Beijing, ...
