Effect of exogenous melatonin on in vivo and in vitro prostaglandin secretion in Rasa Aragonesa ewes.
The effect of exogenous melatonin on prostaglandin secretion was measured on Rasa Aragonesa ewes. Fourteen ewes received an 18 mg melatonin implant (M+) on 10 April and were compared with 13 control animals (without implants M-). Twenty days later, intravaginal pessaries were inserted in all animals to induce a synchronized oestrus (day 0). On day 14, ewes were injected, i.v., with 0.5 IU oxyto...
متن کاملThe effects of exogenous melatonin on wool quality and thyroid function in Rasa Aragonesa ewes
The effect of melatonin on wool quality and thyroid function was studied. Ten ewes received a melatonin implant (M) on March 2004, and 10 ewes which were not implanted served as control (C). At monthly intervals over 12 months, f ibre length and growth were calculated, and plasma thyroxine (T4) concentrations were measured. Wool samples (~N = 2000 fibres) were collected and fibre diameter, stan...
متن کاملEffect of treatment of wheat straw with Pleurotus florida on feed intake, digestibility and body condition score in ewes
This experiment was carried out to compare the effects of treated and untreated wheat straw with Pleurotus florida on ewe feed intake, nutrient digestibility, and ewe body condition score (BCS) after parturition. Thirty Kermani ewes with an average weight of 48 ± 3.05 kg and about four years old were used in this experiment. Synchronization of estrus in sheep has been achieved with the use of i...
متن کاملRepeated superovulation of high-prolificacy Rasa Aragonesa ewes before culling as an inexpensive way to obtain high-quality embryos
The purpose of this study was to assess the ovulatory response and embryo production after repeated superovulation of selected high-prolificacy Rasa Aragonesa ewes at the end of their reproductive life. A total of 211 superovulatory treatments were performed during the breeding seasons of 3 consecutive years. Ewes were given the same gonadotrophin treatment up to three times at intervals of at ...
متن کاملEffects of body condition score at parturition and postpartum supplemental fat on adipose tissue lipogenic activity of lactating beef cows.
Three-year-old Angus x Gelbvieh beef cows nutritionally managed to achieve a BCS of 4 +/- 0.07 (479.3 +/- 36.3 kg of initial BW) or 6 +/- 0.07 (579.6 +/- 53.1 kg of initial BW) at parturition were used in a 2-yr experiment (n = 36/yr) to determine the effects of BCS at parturition and postpartum lipid supplementation on cow adipose tissue lipogenesis. Beginning 3 d postpartum, cows within each ...
