The present study compared the outcomes of in vivo embryo production in Morada Nova ewes subjected to either 9-day (G-9SOV , n = 21) or 12-day (G-12SOV , n = 21) progesterone (P4 )-based estruses synchronization protocol coupled with superovulatory treatment with decreasing doses of porcine follicle-stimulating hormone (133 mg of pFSH given over 3 days). Non-surgical embryo recovery (NSER) was performed 6-7 days after the onset of oestrus. Total antral follicle count doubled from the first to the sixth pFSH dose in both groups (p < .05). Oestrus responses did not vary between the two groups of animals (95.2%). Corpora lutea (CL) were detected in 85.0% and 60.0% of ewes that previously manifested oestrus behaviour in G-9SOV and G-12SOV respectively. NSER was successfully completed in 86.2% of ewes that had CL (p > .05). The mean number of CL per ewe/successfully flushed donor ewe was greater (p < .05) in G-12SOV (12.3 ± 1.7/12.1 ± 1.9) than in G-9SOV (7.9 ± 1.4/8.2 ± 1.6). Mean numbers of retrieved blastocysts and viable embryos were greater (p > .05) in G-12SOV (5.8 ± 1.9 and 3.7 ± 1.7) than G-9SOV (3.5 ± 1.1 and 0.8 ± 0.3 respectively). The total follicle count (all follicles ?2 mm in diameter) at the sixth pFSH dose (at P4 -device removal) was positively correlated (p < .05) with the number of CL (r = .95) and viable embryos (r = .91) in G-12SOV . The ewes with ?10 Cl (48% of all flushed donors) yielded 80.5% of viable embryos. In summary: (a) Morada Nova ewes from G-12SOV group had better superovulatory responses compared with G-9SOV group; (b) total follicle count at the last pFSH dose was a good predictor of superovulatory responses only in the ewes primed with P4 for 12 days; and (c) animals with ?10 ovulations are main contributors to viable embryo production in Morada Nova ewes.

Abstract: Abstract: Research centers are very important to contribute and promote community scientific literacy of children impacts teaching in later grades, promotes the development of conscious citizens regarding the valuation of animal husbandry and food production. Thus, Embrapa has a vital role in society linked to food security through community interaction with agricultural research. The aim of this work was to connect local urban students with animal and botanical sciences and the origin of food, through sensorial and motor skills for a learning associated with daily life. A thematic visit was carried out by 50 students 9-11 years old from the Nossa Senhora Auxiliadora School, Bagé-RS, to Embrapa Southern Livestock, for a variety of forages and ruminants. The children attended the lecture in appropriate language about diet and animal category, different dairy products, animal fat where they saw flipcharts, manipulated dairy packaging, concentrate and roughage ingredients; asked the speakers more than 20 questions. Afterwards, they observed the germoplasm bank: exotic, white clover (Trifolium repens L.), Sudan grass (Sorghum sudanense (Piper) Stapf) BRS Birdsfoot Trefoil (Lotus corniculatus L.) BRS Posteiro; and Herbarium-CNPO with native exsiccates. The high participation of students demonstrated a good receptivity to the actives methodologies. |
