“…ether extract are similar to the digestibility coefficient found for conventional ingredients in other omnivorous species, as in the case of crude protein in the fish meal for tricogaster (Trichogaster leerii), with a digestibility coefficient of 82.19%, and for betta (Betta splendens), with a digestibility coefficient of 82.19% (Tonini et al, 2012), and for betta (Betta splendens), with a digestibility coefficient of 51.15% (Zuanon et al, 2007). The efficient use of vegetal sources of the discus fish above 40% demonstrates the potential of this ingredient in their diets (Chong et al, 2002).…”

In this study, we investigated the occurrence and characterized molecularly Cryptosporidium oocysts in feces of dogs seroreactive for Leishmania spp. We hypothesized that the clinical staging of canine visceral leishmaniasis (CVL) influences the occurrence and intensity of Cryptosporidium spp. oocyst shedding in feces from the canine host due to the immunosuppression induced by Leishmania infantum. Fecal samples from 101 dogs with anti-Leishmania spp. antibodies detected by Dual-Path Platform (DPP®) immunochromatographic test (Biomanguinhos) and/or enzyme-linked immunosorbent assay (Biomanguinhos) were concentrated by the centrifuge-sedimentation method in water-ethyl acetate. The sediments were submitted to the technique of negative staining with malachite green and observed under an optical microscope (400× magnification). The occurrence was 0.99% (95 confidence interval 0.00%- 2.93%). A single Cryptosporidium oocyst was found in one of the samples examined by microscopy, and the result was confirmed by nested-PCR. The amplicon sequence showed 100% genetic identity with Cryptosporidium canis. The dog presented the following clinical signs suggestive of CVL: cachexia, generalized alopecia, pale colored gingival mucosa, splenomegaly, and onychogryphosis. We conclude that there is no evidence that the oligosymptomatic and symptomatic clinical staging of dogs seroreactive for Leishmania spp. influenced the occurrence and intensity of C. canis oocyst shedding in the canine host.

“…Corn is an important energy ingredient used in feed that is rich in starch, which is easily digested by animals. Moreover, the high-quality protein in corn combined with the grinding process leave it exposed and readily available, stimulating rapid digestion (Tonini et al, 2012), which explains the high ADC CP found for this ingredient.…”

ENERGY AND PROTEIN INGREDIENTS FOR USE IN PIAPARA (<i>Megaleporinus obtusidens</i>) DIETS: NUTRITIVE VALUE AND INTESTINAL MORPHOMETRY

et al. 2021

The apparent digestibility coefficients for crude protein (ADCCP), dry matter (ADCDM), and gross energy (ADCGE) of ingredients were determined for piapara (Megaleporinus obtusidens). Test diets were formulated to contain 69.5% of reference diet, 0.5% of chromium oxide, and 30% of test ingredients. The protein ingredients evaluated were tilapia processing residue meal (TPRM), feather and poultry blood meal (FPBM), poultry by-product meal (PBM), meat and bone meal (MBM), cottonseed meal (CM), corn gluten meal (CGM), and soybean meal (SM); the energy ingredients tested were corn (C), corn germ meal (CGRM), rice meal (RM), wheat bran (WB), and sorghum (S). Groups of 30 piaparas were fed twice daily during five days with test diets. Intestinal morphometry of fish were also evaluated. Digestibility coefficients of protein and energy ingredients were highest for soybean meal (ADCDM = 85.8%; ADCCP = 95.2%; and ADCGE = 87.2%) and corn (ADCDM = 94.5%; ADCCP = 76.2%; and ADCGE = 89.3%), respectively. Of the energy test ingredients analyzed, corn had the highest digestibility coefficients and induced beneficial changes on intestinal morphology compared to sorghum and corn germ meal. All protein ingredients showed potential for use in piapara diets, except meat and bone meal .

“…Trichogaster leeri is a good species choice to serve as a model for biological studies as it generates numerous offspring and reproduces easily. In addition, it is commonly sold in ornamental fish shops (Tonini et al 2012). Despite the unique characteristics of this species, few studies have been conducted that describe aspects of its early ontogeny.…”

Temperature is an environmental factor that influences the development of fish, and when changed abruptly can lead to high mortality. Some species of fish are influenced by this factor, exhibiting a longer time for embryonic development and time to first feeding. This study aims to evaluate the effect of water temperature on embryonic and larval development up to first feeding, to describe the time in hours post fertilization (hpf) of the emergence of different structures and to determine the best hatching rate and survival of animals under different treatments. Five different egg incubation temperatures were used (24, 26, 28, 30 or 32°C, respectively). The eggs were observed at regular intervals of 30 min up to 24 h, every 2 h until 48 h and every 4 h until the display of first feeding in all treatments. Embryonic development was longer for eggs incubated at 24°C and the best results for hatching rate and survival of spawning efficiency were at 28°C. We recommend that incubation of Trichogaster leeri eggs is carried out at 28°C up to the first feeding of larvae.
