Abstract The aim of this study was to compare embryo production efficiency in Flemish and Holstein donor females using ovum pick-up and in vitro fertilization (OPU-IVF) or in vivo production (superovulation; SOV) procedures. The study was conducted using a split-plot design, with eight Flemish and eight Holstein non-lactating cycling females. Females were subjected to ten weekly OPU/IVF sessions and/or two SOV/embryo collections sessions at a 63-day interval, for a total of 160 OPU-IVF and 32 SOV sessions. Mean numbers of follicles and corpora lutea, and cumulus-oocyte complex (COC) recovery rates were similar between breeds after the OPU and SOV sessions. However, Flemish donors yielded better quality grade II COCs (301, 41.9%) than Holstein females (609, and 202, 33.1%). Also, cleavage and blastocyst rates, and the total number and the mean number of viable embryos obtained after OPU-IVF were higher in Flemish (49.6% and 11.8%, and 63 and 11.8 per donor, respectively) than in Holstein (32.8% and 7.2%, and 34 and 7.2 per donor, respectively) females. Flemish females were also more efficient in yielding viable embryos after SOV (111, 7.3 per donor) than Holstein (48, 3.3 per donor) females. Overall, Flemish donor females had better responses to OPU-IVF or SOV procedures than Holstein counterparts. Irrespective of the breeds, SOV procedures were more efficient than OPU-IVF in yielding more viable embryos, under the conditions of this study. Both reproductive procedures were useful tools for the genetic conservation of the Flemish cattle breed in Southern Brazil.

ABSTRACT We conducted an experiment to evaluate the effect of different inclusion rates and routes of administration of Ganoderma spp. on growth performance and gut morphology in broilers. We randomly assigned 320 one-day-old male broilers (Ross 308) to eight treatments with the same basal diet. Performance parameters were food intake (FI), body weight gain (BWG), and feed conversion ratio (FCR). Treatments were a basal diet (NC) with 55 ppm of bacitracin methylene disalicylate BMC (PC), basal diet with Ganoderma at 50 ppm, 100 ppm, and 150 ppm in drinking water (WG50, WG100, WG150), and feed (FG50, FG100, FG150). Body weight gain was higher for FG150 compared with NC. Treatment FG150 and PC had the best indicators of intestinal morphometry, showing significant differences on villi height to crypt depth ratio compared with other treatments. Ganoderma supplementation may be an alternative for the replacement of growth-promoting antibiotics because it offers comparable results to those generated by bacitracin methylene disalicylate (BDM).

The genus Marchella Dill. ex Pers. (Ascomycota, Pezizales) is registered for the first time as the only representative of the Morchellaceae family for the Colombian mycobiota. The ascocarp was collected in a cloud montane forest, in the village of Santa Helena, municipality of Gachalá, department of Cundinamarca. The specimen is described and illustrated with photographies, and information on distribution, ecology and growth substrate is provided. The taxonomic identity of the specimen is discussed according to the traditional morphological concept established in the mycological literature. With this report, the order Pezizales in Colombia is constituted by 17 species contained in 12 genera and 7 families.
