In sheep, the seasonal patterns of reproductive activity are driven primarily by annual photoperiodic cycle, but can also respond to other environmental factors, such as nutrition, yet little is known about mechanisms underlying this interaction. This study was designed define interaction between and nutritional cues on ovarian activity, determine if there a central these cues. Groups Ile-de-France ewes were maintained in two states (restricted well fed) under simulated photoperiod 8-16 h...
A tremendous evolution has taken place in the field of equine reproduction during past decade.Advanced techniques, such as ovum pick up combined with intracytoplasmic sperm injection and embryo transfer, have become more routine procedures warmblood breeding.These techniques allow 'popular' mares to produce multiple foals per year via surrogate mares.The latter impression that only a limited number popular stallions are preferred by breeders due strong selection, could generate fast-paced...
A short-term increase in food intake and specifically dietary energy can stimulate folliculogenesis ovulation rate ewes. The mechanism appears to involve the insulin-glucose metabolic system its interaction with FSH signalling pathways granulosa cells of ovarian follicles. This experiment was designed investigate between these two systems Thirty six Ile-de-France ewes were used this controlled study effects intravenous glucose on folliculogenesis. Eighteen infused (10 mM/h for 72 h) from day...
It is now widely accepted that AMP-activated protein kinase (AMPK) a critical regulator of energy homeostasis. Recently, it has been shown to regulate circadian clocks. In seasonal breeding species such as sheep, the clock controls secretion an endogenous rhythm melatonin and, consequence, probably involved in generation rhythms reproduction. Considering this, we identified presence subunits AMPK different hypothalamic nuclei pre- and post-pineal pathways control seasonality reproduction ewe...
The aim of this study was to determine the effects short-term feed supplementation Lemuru fish oil on reproductive performance 20 primiparous Garut ewes.For purpose, four diets were compared: a control diet (C) and three with various supplements.These were: 6% palm (P1), 3% (P2), (P3).Experimental ewes subjected estrous synchronization using two injections PGF2α 11 days apart.The hormonal profiles blood metabolites monitored for animals each group.Estrous expression observed at mating,...
Shortage and refeeding situations lead to switches in metabolic pathways induced by undernutrition body energy reserve (BR) replenishment cycles. In a 122-d experiment, 36 adult Merinos d'Arles ewes were chosen first accustomed diet ingredients (i.e., wheat straw, pelleted alfalfa sugar beet pulp) the facility environment for 22 d. Then, randomly assigned one of three "diet challenge" treatments during 50 d, (control, underfed overfed; 12 each) corresponding 100%, 70% or 160% requirements...
As a teaching subject, animal welfare is challenging for educators and learners, as was recently shown in recent survey on the evolution of Europe. Among several suggestions to overcome current resistance implementing education, we highlight two. The first that education should be based learner-centred approaches; second it encompass both science ethics law. To best our knowledge, there are no pedagogical approaches can simultaneously explore scientific ethical concepts. Furthermore, when...
Chez les Équidés, mises-bas ont lieu au printemps, conséquence d'une période sans ovulation commençant vers octobre pour s'achever fin avril. Pour éleveurs, une avance de la première est capitale car elle augmente part, le nombre cycles utilisables et d'autre l'âge réel moment l'épreuve sportive ou l'abattage. juments, l'avance maximale date annuelle, sous nos latitudes, obtenue avec un éclairement quotidien 14h30, solstice d'hiver pouvant être interrompu bout 35 jours longs (JL).
