Pesquisa de salmonella em mutuns (mitu mitu) mantidos em cativeiro

We collected 50 samples of curasow feces from the Scientific and Cultural Breeding Center in the city of Poços de Caldas. The samples were enriched in broth medium Tetrationato and Cystine-selenite and plated on Salmonella Shigella (SS), Mac Conkey (MC), endo-C (EC), Brilliant Green (VB) and Eosyn Methilen Blue EMB, remaining at 37 °C for 24h. Colonies suspected of Salmonella were inoculated in tubes containing Agar Triple Sugar Iron (TSI) and again incubated at 37 ºC for 24h. Tubes with characteristic growth were submitted to slide agglutination test with polyvalent somatic and flagellar serum. The medium SS, MC and VB were the most efficient for growing, and 36% of samples were positive for Salmonella spp. As birds are important reservoirs of Salmonella spp and it may represent a high risk to human health, there is a need to implement a cleaning routine in enclosures avoiding contamination between the enclosures and the consequent entrainment of these micro-organisms, by the keepers until their homes or other venues. The presence of Salmonella in breeding centers may be responsible for lower hatchability of eggs, undermining the purpose of the entity, which is to study and maintain the various birds species.

Inorganic and organic trace mineral supplementation in weanling pig diets

A study was conducted to evaluate the s of dietary inorganic and organic trace minerals in two levels of supplementation regarding performance, diarrhea occurrence, hematological parameters, fecal mineral excretion and mineral retention in metacarpals and liver of weanling pigs. Seventy piglets weaned at 21 days of age with an average initial body weight of 6.70 ± 0.38 kg were allotted in five treatments: control diet (no added trace mineral premix); 50% ITMP (control diet with inorganic trace mineral premix supplying only 50% of trace mineral requirements); 50% OTMP (control diet with organic trace mineral premix supplying only 50% of trace mineral requirements); 100% ITMP (control diet with inorganic trace mineral premix supplying 100% of trace mineral requirements); and 100% OTMP (control diet with organic trace mineral premix supplying 100% of trace mineral requirements). Feed intake and daily weight gain were not affected by treatments, however, piglets supplemented by trace minerals presented better gain:feed ratio. No differences were observed at calcium, phosphorus, potassium, magnesium, sodium and sulfur excreted in feces per kilogram of feed intake. Treatments did not affect calcium, phosphorus, magnesium, sulfur and iron content in metacarpals. Trace mineral supplementation, regardless of level and source, improved the performance of piglets.

Diagnóstico parasitológico de horticultures no monitoramento da contaminação parasitária em ambientes rurais

The objective of this study was to detect possible carriers of parasites and/or commensals between the horticulturists of Fair of the Producer from Upper Paranaiba, Minas Gerais. A total of 30 horticulturists were instructed to collect three stool samples on alternate days during the months of August and September 2007. Horticulturists were positive 40% for one or more parasite and / or dinner, and found: Giardia lamblia (3.5%), Entamoeba histolytica / E. dispar (7%), Entamoeba coli (13%), Endolimax nana (13%) and Ascaris lumbricoides (3.5%). Stool of gardeners is of importance in monitoring parasite sanitary conditions of vegetables sold in urban environments.

Suplementos múltiplos para novilhas de corte a pasto no período seco: características nutricionais

The objective was to evaluate levels of multiple supplements supplied to beef heifers in low supply of pasture on intake and nutrients digestibility, pH and concentration of ruminal ammonia nitrogen, nitrogen balance, synthesis and microbial efficiency. Five Nellore heifers with initial body weight of 344.00 +/- 21.10 kg and average initial age of 22 months were used. The following supplements were evaluated as fed to the animals: control (mineral supplement) and supplementation levels of 2, 4, 6 and 8 kg/animal/day, composing the following percentages of body weight (BW): 0.55, 1.11, 1.66 and 2.22%, respectively. The experimental design was a Latin square with five replications and five supplements. Intakes of total dry matter, crude protein (CP) and total digestible nutrients, and total apparent digestibility of dry matter, crude protein, total carbohydrates and no fiber carbohydrates increased linearly (P <0.0001) and dry matter intake of forage decreased (P <0.0001) with supplementation levels. Supplementation strategies promoted reduction on ruminal pH (P = 0.0343) and increased concentration of ruminal ammonia nitrogen (NH3-N) (P = 0.0004) before the supply of supplements, and after, this NH3-N presented quadratic behavior (P = 0.0023). Nitrogen intake, excretion of urea in urine and nitrogen excretion in feces increased linearly (P <0.0001) according to supplementation levels. The supply of high levels of multiple supplements reduces forage intake and presents itself as an alternative to cattle maintained in a systems with low supply of pasture in the dry season.

Retrieval of Trichostrongylus colubriformis infective larvae from grass contaminated in winter and in spring

The survival of infective larvae (L3) of Trichostrongylus colubriformis was evaluated on Brachiaria, Coast-cross and Aruana forage grasses. Feces of sheep parasitized exclusively by T. colubriformis were deposited in winter and spring on experimental plots whose grasses were cut at two heights: 5 cm and 30 cm. One, two, four, eight, 12 and 16 weeks after depositing the feces, fecal and forage samples were collected for the retrieval and quantification of L3. Retrieval of L3 from feces and forage was negligible in winter due to the dry weather, although a few larvae were retrieved in the last larval collections. However, L3 retrieval from fecal samples was greater in spring, especially two weeks after feces were deposited on 30 cm high grasses. At this time, the L3 retrieval rate from the three forage grasses differed significantly (P < 0.05), with Aruana grass showing the highest average L3 retrieval rate, followed by Coast-cross and Brachiaria. In conclusion, the winter drought proved very unfavorable for the presence of L3 in the environment, and the microclimate of Aruana pastureland was generally the most favorable for the retrieval of infective larvae.

Tempo de trânsito gastrointestinal de diferentes frutos e taxa de germinação de Morus nigra pós passagem pelo trato em Sabiás-barranco (Turdus leucomelas)

Seed dispersal is a key process in the life cycle of plant species and may determine the dynamics of their populations. The passage of the fruit from the gastrointestinal tract brings effects on energy and nutritional rewards for the bird. The retention time of the seeds is an essential factor for the dispersion, affecting the dispersal distance. Some factors determine it, as the size of the bird, degree of frugivory, chemical composition of the fruit, the number and size of seeds. The study sought to characterize the Morus nigra seed retention time in three species of thrushes and compare them with other species of birds and plants. The blackberry, exotic species with socio-economic importance in Brazil, produces aggregate fruit having up to 60 seeds. Have been kept in captivity individuals leucomelas Turdus rufiventris thrush, thrush and amaurochalinus, native and omnivorous species, important dispersers in degraded areas, inhabiting the urban and the natural environment. In 274 samples of feces was recorded about 500 mulberry seeds. The first record of seeds was in 15 minutes (n = 2) and the last to 115 minutes (n = 4) after eating the fruit. The average time of gastrointestinal transit of seed for the three species was 52 minutes and 80% were defecated to 65 minutes post ingestion. Taking into consideration the type of fruit and the species of bird, there is great variation in the retention time when compared to other species of birds, being in general slower. That way, can be increase the degree of dispersion of the seed to more distant areas of the mother plant, increasing the chances of survival of seedlings, according to the hypothesis Janzen and Connell. The Turdus It showed efficient dispersers Morus nigra seeds, and inhabits natural and urbanized environment, the possibility of exchange of these seeds between environments by the action of thrushes
