Digestible lysine levels for laying hens and their effects on egg quality

Egg quality of semi-heavy laying hens fed on low protein diets (14.0% CP) and on different lysine levels is evaluated, while maintaining the same ratio of digestible amino acids / digestible lysine. Four hundred and twenty commercial strain Isa Brown laying hens, 28 weeks old, were divided into 42 experimental plots. A completely randomized design with six treatments and seven replicates was employed in four production cycles of 28 days each. Treatments comprised Control - 16.92% CP; 0.750% digestible lysine. Treatments 1 to 5, with CP levels 14% and digestible lysine levels 0.600, 0.675, 0.750, 0.825 and 0.900% respectively. Levels of Treatments 1 and 2 (0.546 and 0.640% digestible Met + Cys / 0.600 and 0.675% digestible lysine) provided smaller egg size. On the other hand, eggs had higher shell percentage when compared to control diet. When compared to other digestible amino acids, digestible lysine requirement may be estimated at 0.750% in a diet with 14% CP, which corresponds to the average daily intake of 876 mg dig. lysine hen-1 day-1 and 798 mg dig. Met + Cys hen-1 day-1, without jeopardizing performance and eggs' internal and external quality.

Detecção de Salmonella Enteritidis em ovos de codornas japonesas submetidas a dietas com diferentes níveis de cálcio e fósforo

The eggs are pointed in several studies as the main cause of human salmonellosis. Have been identified that eggs are eaten raw or poorly processed are mainly responsible for outbreaks of human infection with Salmonella spp. Besides causing problems to public health, the presence of bacteria impedes or hinders the international food trade, as a sanitary barrier. Several factors predisposing to contamination of the internal contents of eggs for Salmonella spp., including the egg shell quality (shell quality), which is related to levels of calcium (Ca) and phosphorus (P) in the diet of quails . The experiment used eggs of Japanese quail under different diets containing two levels of Ca (2.0 and 3.5%) and two levels of available P (0.25 and 0.45%). Eggs of 120 japanese quails were divided into four treatments with three replicates. The experiment was divided into three production stages: initial, intermediate and final. Were assessed at each stage the presence of bacteria in internal and external content of experimentally contaminated eggs during periods of 0, 24, 96 and 168 hours after immersion in broth containing Salmonella Enteriditis. Salmonella Enteriditis was detected in the shell during all periods of storage, in decreasing amounts in all treatments. None of the treatments within the three production stages analyzed, we detected significant amounts of the bacteria inside the egg, in our experimental conditions. Therefore, the levels of Ca and P in the diets of quail do not determine higher or lower risks to public health represented by eggs

Manejo no incubatório que afeta a eclodibilidade de ovos de galinha (Gallus Gallus Domesticus)

In the process of artificial incubation of fertile eggs of chicken (Gallus gallus domesticus) there are procedures that, they are not hindered the birth, they cause embryonic mortality. Handlings before incubation as disinfection and storage are capable to reduce the embryonic if accomplished of inadequate way viability. Already in the incubation process properly says, irregularities in variables as temperature, turning, humidity and ventilation in the incubator reduce the hatchability, what means that, of the total of fertile eggs there is reduction in the number of born chicks, there is like this the reduction of profit of the incubator, being necessary an analysis of which they interfered in the birth

Efeito de hipercabia no desenvolvimento de ovos de Trachemys scripta

Females of the painted turtle, Trachemys scripta, have an annual reproductive cycle. Their nest periods in Brazil starts around September and they lay about 7 - 10 eggs in nests dug in the soil. The eggs hatch in December. It is possible that the nest cover cause problems for the gas diffusion, also, the rain can wet or compact the soil covering the nest, or even soaked the whole area. Those problems may change the nests intern atmosphere decreasing O2 partial pressure (hypoxia) and increasing CO2 partial pressure (hypercarbia). The main objective of this study was to determine if and how hypercarbia (3% and 6%CO2), could influence the eggs and early posthatching development of the Trachemys scripta. We used three experimental groups of eggs incubated in: normal atmosphere (Control group CG, n = 14), hypercarbia with 3% of CO2 (G3%, n = 16) and with 6% of CO2 (G6%, n = 15). The profile of the mass increment during the egg development were not different among the groups, GC = 9.89±0.81g; G3% = 10.11±0.60g and G6% = 10.58±0.36g. In addition, the mass of the post-hatching turtles were the not different. There were not differences between the duration of the incubation period among the experimental groups, GC = 60.12±0.97days, G3% = 59.00±0.98days and G6% = 60.80±1.14days. The mortality rates were not affected by the hypercarbia, GC = 0.43 (43%), G3% = 0.27 (27%) and G6% = 0.37 (37%). Furthermore, the mass increment and the metabolic rate were the same among the early development of the turtles until 3 month after hatching. We conclude that hypercarbia (up to 6% of CO2) does not cause any alteration on the eggs or post-hatching normal development. It is possible that the combination of hypercarbia and hypoxia change those results
