Smaniotto,B.D.; Amarante,A.F.; Altarugio,R.; Silva,I.G.O.; Corrêa,I.M.O.; Pereira,L.Q.; Sartori,M.M.P.; Andreatti Filho,R.L.; Guimarães-Okamoto,P.T.C.; Okamoto,A.S..
ABSTRACT This study evaluated the influence of the bird’s age on the quality of the shell and percentage of bacterial penetration in commercial eggs. White-shelled commercial eggs were used, laid by light laying hens in their first laying cycle at 21, 39, 51, and 62 weeks of age. Shell quality evaluations comprised: egg weight, specific gravity, percentage and thickness of shell, number and size of pores. For evaluations regarding bacterial penetration, strains of several enterobacterias and one salmonella were used, all of which resistant to Nalidixic acid (100µg/ml). The method employed for evaluation of bacterial penetration was filling the eggs with growth medium. The data were subjected to variance analysis with 5% of probability using SAS (Education...

ANTHROPOGENIC IMPACTS ON YELLOW-SPOTTED RIVER TURTLE Podocnemis unifilis (REPTILIA: PODOCNEMIDIDAE) FROM THE BRAZILIAN AMAZON Acta biol.Colomb.
Santos ARRAES,Débora Regina; Albuquerque CUNHA,Helenilza Ferreira; TAVARES-DIAS,Marcos.
The purpuse of this study was to investigated the influence of anthropogenic impacts on Podocnemis unifilis nesting on a stretch from Falsino river, with two forest reserves, and one urban area on the Araguari river, state of Amapá, eastern Amazon (Brazil). A total of 180 nests were found, being 89.4 % in the forest reserves and only 10.6 % in urban areas. On Falsino river, we observed a spawning pattern, because the number of nests was correlated to the length and width of the nesting locations. On Araguari river, the P. unifilis nests were generally found in areas with surrounding vegetation up to 5 meters in height, minimum distance of 120 meters from residences and immediately or after places of higher exploration of pebbles. Females from Falsino river...

Bioenergética del besugo Pagrus pagrus. OceanDocs
Aristizabal, E.O..
The utilization of the energy of food by red porgy (Pagrus pagrus Linnaeus, 1758) from the Argentine Sea (SW Atlantic) was studied. From the energetic point of view, it is proposed that the strategy of patitioning, utilization and storage of the energy of food, is an indicator of the organism response to the environmental conditions. The main objective was to know the proportion of the energy of food derived to the different components of the bioenergetics budget. In order to estimate the monthly energy investment in reproductive growth, chemical analysis of gonads from fishes caught by the fishery fleet and from laboratory studies were performed. Two indexes were used to calculate the energy investment in female ovaries: the proportion of net daily energy...

Bambill, G.A.; Oka, M.; Radonic, M.; López, A.V.; Müller, M.I.; Boccanfuso, J.; Bianca, F..
The present study was conducted to determine the parameters regulating spawning performance of P. orbignyanus wild broodstock. The adaptation to captivity was successfully achieved with minimal stress levels. In three consecutive spawning seasons, the annual photothermal manipulation was not effective for the maturation and natural spawning of females although males were running. Females were HCG injected, releasing non fertilized eggs. Artificial fertilization was carried out after stripping the fish with a total production of 18,000 fertilized eggs in 2001 (egg diameter=800±10 µm), 55,300 in 2002 (egg diameter= 850±12 µm)and 1,635,000 fertilized eggs in 2003 (egg diameter 818.4 ±30.08 µm, oil drop 98.1 ±2.96 µm).

Campylobacter sp in eggs from cloacal swab positive breeder hens BJM
Fonseca,Belchiolina Beatriz; Soncini,Ricardo Alfredo; Gimarães,Adelia Rodrigues; Rossi,Daise Aparecida.
Campylobacter sp is a microaerophilic, thermotolerating Gram negative bacterium, known to be one of the main causes of food-borne human infections. Among the foods that carry these microorganisms, the chicken is outstanding. In Brazil, a large chicken exporting country, few researches are conducted about their prevalence in breeder hens and the transmission through eggs. The aim of this research was to verify the presence of Campylobacter sp in the shells and within the eggs from positive cloacal swab breeder hens. Microbiological analyses were made on cloacal swabs of 140 weighed breeder hens. The positive breeder hens were set aside and in a total of 244 of their eggs, Campylobacter sp was present in macerated shells and yolk contents during 7 weeks. Out...

Comparison on animal production in organic and conventional systems MV&Z
Rossi, Gabriel Augusto Marques; Lemos, Paulo de Paula Lopes.
The market for organic products is increasing globally, seeking to fulfill the needs and expectations of consumers who believe it’s a healthier food. There are many controversies found in studies that assess primarily the physical-chemical, microbiological and the presence of this type of food of animal origin. This review aimed to evaluate the main differences between animal foods such as meat, milk, honey, eggs and fish produced in organic systems compared to those produced in conventional systems. The main differences are related to the physical-chemical food and no relevant differences were found between the possible presence of chemical or biological hazards in food of animal origin.

Machado,Gilmara Junqueira; Murgas,Luis David Solis; Palhares,Priscila Cotta; Assis,Isadora de Lima; Castro,Tássia Flávia Dias.
ABSTRACT This study aimed to evaluate the effect of using different concentrations (5, 7.5, 10, and 12.5%) of two permeating cryoprotectants, dimethyl sulphoxide (DMSO) and methanol, on Prochilodus lineatus embryos while being subjected to cooling for 2, 4, 6, and 8 h at 4 °C. We analyzed the hatching rate, viable larvae, and counts of hatched and spoiled eggs and those that did not complete their development after cooling. We observed a significant interaction among variables, permeable cryoprotectant concentration, and cooling time, having the increase of these factors caused a reduction in hatching rate. The curimba embryos showed a higher sensitivity to cold at a temperature of 4 °C for 6 and 8 h, directly influencing the production of viable larvae....
