Resumo - Foram avaliados os efeitos do tempo de amostragem e do pH ruminal sobre a concentração de protozoários ciliados no rúmen de cinco ovinos mestiços Santa Inês, fistulados no rúmen, mantidos extensivamente em pastagem natural de caatinga no município de Sertânia, PE. As amostras de conteúdo ruminal foram obtidas nos seguintes horários: zero hora (antes dos animais serem soltos na pastagem, às 7:00h) e 2, 4, 6, 8 e 10 horas depois de iniciado o pastejo. As amostras obtidas foram fixadas em formalina 18,5% (v/v). Foram identificados e quantificados organismos dos gêneros Dasytricha, Diplodinium, Diploplastron, Entodinium, Eodinium, Elytroplastron, Enoploplastron, Epidinium, Eremoplastron, Eudiplodinium, Isotricha, Metadinium e Ophryoscolex, sendo que, desses, apenas Diploplastron e Entodinium apresentaram variações na concentração de suas populações em função do horário de amostragem. O número de ciliados em divisão não apresentou correlação com o horário de amostragem, sendo que a estabilidade das taxas de divisão parece contribuir para a manutenção das concentrações dos ciliados no rúmen. O pH ruminal não apresentou correlação com o número de protozoários, provavelmente, porque as variações observadas compreenderam valores considerados limítrofes para o estabelecimento e manutenção das populações de protozoários no rúmen.

Abstract - Effects of the sampling time and ruminal pH on the concentration of ciliate protozoa in the rumen of five fistulated Santa Inez crossbred sheep, reared in natural caatinga (scrubland) pasture were evaluated. Ruminal content samples were obtained at zero hour (before the animals were released to the pasture, at 7:00h) and 2, 4, 6, 8 and 10 hours thereafter. Samples were fixed in formalin at 18.5% (v/v). It was identified and quantified organisms of the genera Dasytricha, Diplodinium, Diploplastron, Entodinium, Eodinium, Elytroplastron, Enoploplastron, Epidinium, Eremoplastron, Eudiplodinium, Isotricha, Metadinium and Ophryoscolex. Among them, only Diploplastron and Entodinium presented variations at their population concentrations in function of the sampling time. The number of ciliates undergoing division was not correlated with the sampling times. Stable division rate seemed to contribute the maintenance of ciliates concentrations in the rumen. Ruminal pH was negatively correlated with sampling time, and was not correlated with the number of protozoa, probably because the variations observed included parameters considered ideal for establishment and maintenance protozoa populations of rumen.

Forage cultivar diversification reduces risk in forage-livestock systems. Ipyporã brachiariagrass (Brachiaria 'BRS RB331 Ipyporã') (B. ruziziensis × B. brizantha) was released in 2017 for use in areas where spittlebug [Deois flavopicta, Notozulia entreriana and Mahanarva spp.] is a challenge. Our objective was to compare forage production in Ipyporã and standard cultivar Mulato II (B. ruziziensis × B. brizantha × B. decumbens) under continuous stocking during May 2016 to May 2018 in the Amazon Biome (Sinop, MT, Brazil). The experimental design was a randomized complete block with four replicates (1.5-ha pastures). Average canopy height was maintained at 30 ± 5.0 cm.Mulato II presented greater herbage accumulation (HA; 17360 kg DM ha-1) and herbage accumulation rate (HAR; 55 kg ha-1day-1) than Ipyporã (14930 kg DM ha-1and 48 kg ha-1day-1, respectively) across the two years. Mulato II crude protein concentration was 10 g kg-1 greater than Ipyporã. Spittlebugs were present only during the rainy season, and foliar damage occurred only in Mulato II pastures. Both cultivars had greater HA, HAR during the rainy season in the first year (2016/2017) compared with the second year (2017/2018). The first year was the pasture establishment year, with a shorter period of water deficit (30 days less) and greater rainfall (2147 mm) than the second year (1762 mm). Our data indicate that if greater productivity is desired, Mulato II provides greater HA than Ipyporã when adequate pest monitoring and pest control are implemented. However, systems based on Mulato II will have greater risk and require more attention and decision making by managers. Although Ipyporã had lesser HA, there was no concern about spittlebugs in this severe risk region, which confirms Ipyporã as an alternative for diversification of forage-based livestock systems in the Amazon Biome.
