Abstract: This study compared the effects of intravaginal and intravenous routes of oxytocin (OT) administration in 46 oestrous-induced Santa Inês ewes (6-day treatment with progestin-releasing intravaginal sponges and a single injection of 200 IU of eCG at the time of sponge removal) that underwent transcervical embryo recovery 6-7 days after oestrous onset and mating. All ewes received 37.5 ug of d-cloprostenol via latero-vulvar route, and 1 mg of oestradiol benzoate i.m. 16 hr before and 50 IU of OT 20 min before non-surgical embryo recovery (NSER), with OT being administered intravenously (n = 21) or intravaginally (n = 21). An overall oestrous response was 95.6% (44/46), and adequate cervical retraction could be accomplished in 78.6% (33/42) of ewes. The percentage of successful NSER procedures was 57% (24/42) or 72.7% (24/33) of animals with sufficient cervical retraction. The duration of NSER procedure averaged 28 min (range: 17-40 min) and ~96% of flushing fluid could be recovered (range: 85%-100%). Out of 18 ewes that could not undergo NSER, 12 (66.6%) presented various anatomical barriers, whilst the other 33.4% did not present these barriers and still could not be traversed. Excluding the ewes with those anatomical features, the overall success rate of NSER was 80% (24/30). The route of OT administration had no effect on NSER efficiency or the ease with which transcervical embryo flushing was performed. Both routes of OT administration can be used for cervical dilation protocol. Discarding ewes with anatomical features precluding cervical penetration is highly recommended to increase the efficacy of NSER in sheep.

Foi realizado um experirnento no Centro Nacional de Pesquisa de Agrobiologia, Seropédica-RJ, com objetivo de comparar as gramineas Coast cross e Tifton 85, do gênero Cynodon, e as gramíneas Suazi (Digitaria swazilandensis) e Transvala (D. decumbens), do gênero Digitaria, quanto a produção de matéria seca (MS) e teores de macronutrientes da parte aérea e sistema radicular, em 15 amostras de cada cultivar, coletadas no período das chuvas (primavera/verão). A análise discriminante demonstrou que as variáveis Mg, Ca e MS na parte aérea e P e N na raiz foram importantes no processo de discriminação dos cultivares estudados. O cultivar Suázi foi diferente dos dernais avaliados quanto a produção de MS e aos teores de Mg e Ca na parte aérea, além do P e N na raiz. Os cultivares Tifton 85 e Coast cross, apesar de serem do mesmo gênero, diferem quanto a produção de MS e aos teores de Mg e Ca na parte aérea, alem do P e N na raiz. Algumas amostras dos cultivares Tifton 85 e Coast cross apresentaram semelhança com O capim Transvala, com relação a produção de MS e aos teores de Mg e Ca na parte aérea, alem de P e N na raiz. An experiment was carried out at the National Center of Research of Agrobiology, Seropedica--RJ, with objective of evaluating the grasses Coast cross (Cynodon spp.) and Tifton 85 (Cynodon dactylon (L.)), of the Cynodon genus, and the grasses Suazi (Digitaria swazilandensis) and Transvala (Digitaria decumbens), of the Digitaria genus, through the discriminant analysis. The evaluated variables were: dry matter production (DMP) and contents of nitrogen (N), phosphorus (P), magnesium (Mg) and calcium (Ca) in the shoot and root on 15 samples of each grasses, accomplished in the period of the rains (spring/ summer). The discriminant analysis demonstrated that the variables Mg, Ca and dry matter production (DMP) in shoot, and P and N root are important in the discrimination process of the Coast cross, Tifton 85, Suazi and Transvala cultivars. Suazi cultivar is clearly different from the others cultivars, in relationship to Mg and Ca contents and DMP at the shoot, P and N at the root. O Tifton 85 and Coast cross cultivars, in spite of being of the same genus, differ in relationship to Mg and Ca contents and DMP at the shoot, match and N at the root. Some samples of the Tifton 85 and Coast cross cultivars can be similar to the grass Transvala, in relation to the Mg, Ca and DMP contents in shoot, P and N root.
