Abstracts: This study aimed to define areas suitable, and the irrigation water requirement for, cultivation of Tanzania guineagrass in the state of Ceará, Brazil. Tanzania guineagrass yield was estimated by a mathematical model, which considers the crop actual evapotranspiration, resulting from the crop climatological water balance. The water requirement throughout the year was estimated for soils with a water holding capacity of 20 (shallow soils), 40 (sandy soils), 60 (soils with medium texture) and 100 mm (clay soils). The relative frequency of occurrence of monthly productions greater than 2,750 kg DM ha-1 month-1 was obtained for different areas in Ceará, representative of most of the state's economic mesoregions. Tanzania guineagrass annual yields in the state of Ceará were between 20,000-30,000 kg DM ha-1 year-1 . During the rainy season, the productive potential varies with the economic mesoregion, which presents different climatic conditions. The state of Ceará is only suitable for the rainfed production of Tanzania guineagrass for 4 months each year, predominantly from February to May, while weather conditions do not favor the development of this grass in the remaining months. [Agro-climatic suitability and water requirement for Tanzania guineagrass cultivation in the State of Ceará]. Resumo: O objetivo desse trabalho foi delimitar áreas aptas e o requerimento hídrico de irrigação para cultivo do capim Tanzânia no estado do Ceará. A produtividade do capim Tanzânia foi obtida a partir de um modelo matemático que assume os valores da evapotranspiração real, resultante do balanço hídrico climatológico da cultura. A necessidade hídrica para reposição de água ao longo do ano para solos com capacidade de água disponível de 20 (solos rasos), 40 (solos arenosos), 60 (solos de textura média) e 100 mm (solos argilosos). A partir da TAMS obteve-se a frequência relativa de ocorrência de produtividade mensal em diferentes municípios Cearense. Os valores de produtividade do capim Tanzânia no estado do Ceará predominaram entre 20.000 e 30.000 kg MS ha-1 ano-1. Durante os meses chuvosos o potencial produtivo varia em função da mesorregião econômica, as quais apresentam condições climáticas distintas. Portanto, o estado do Ceará possui aptidão para produção do capim Tanzânia, sob regime de sequeiro, durante apenas quatro meses, predominantemente, de fevereiro a maio, sendo que as condições climáticas não favorecem o desenvolvimento do capim nos demais meses.

Abstract: 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.
