In Ovo Feeding

The objective of this research was to evaluate techniques, incubation period, and effects of amino acids in ovo feeding. First, 240 hatching eggs were selected and distributed in a 2 × 3 factorial arrangement (two techniques and 3 d). The parameters of incubation, relative weight of gastrointestinal organs, and classification of embryonic mortality were evaluated. In the second stage, 720 hatching eggs were incubated with five treatments: control, methionine (20 and 30 mg), and lysine (20 and 30 mg). These animals were housed during 14 d. The animals were divided with five treatments, nine replicates, and groupings based on sex. Incubation parameters, performance, intestinal morphometry, and relative weight of digestive tract organs were evaluated. The results indicate that the technique using a 45° needle axis passing through the air chamber hinders hatchability. In the organ weighing, there was no difference between the evaluated factors. For intestinal morphometry, there was only a significant difference between the dose factor for the crypt villi and crypt diameter. To conclude, the technique using a 90° angle without passing through the air chamber is safer for the embryos. The inoculation of methionine (20 and 30 mg) obtained data similar to the control group.

In Ovo Feeding

AbstractOver the years, due to genetic selection, improvement of the characteristics of laying and meat poultry with less feed consumption per kilogram of body weight gain has been achieved (FCR). As the productivity of poultry increased, the demand of embryos for nutrients changed. However, the chemical composition of an egg has remained practically unchanged, and therefore, it began providing the embryos with suitable substances with the help of in ovo technology. Improvements in hatching were achieved through the administration of fructose, sucrose and grape seed extract (GSE), while the weight of a one-day-old chick is affected by the injection of amino acids with glucose and magnesium. In addition, amino acids and carbohydrates applied to an egg have contributed to an increase in the activity of digestive enzymes and maturation of the intestine. In connection with early stimulation of the intestinal tract of broiler chicks, they obtained higher weight gain. Supplementation with vitamins positively affects the increase of birds’ immunity and body weight at the end of breeding. On the other hand, the injection of an insulin-like growth factor (IGF-I) influenced the growth and development of muscle tissue during the first weeks of life.

The Difference

Multidrug resistance-associated protein 3 (MRP3), unlike other MRPs, transports taurocholate (TC). The difference in TC transport activity between rat MRP2 and MRP3 was studied, focusing on the cationic amino acids in the transmembrane domains. For analysis, transport into membrane vesicles from Sf9 cells expressing wild-type and mutated MRP2 was examined. Substitution of Arg at position 586 with Leu and Ile and substitution of Arg at position 1096 with Lys, Leu, and Met resulted in the acquisition of TC transport activity, while retaining transport activity for glutathione and glucuronide conjugates. Substitution of Leu at position 1084 of rat MRP3 (which corresponds to Arg-1096 in rat MRP2) with Lys, but not with Val or Met, resulted in the loss of transport activity for TC and glucuronide conjugates. These results suggest that the presence of the cationic charge at Arg-586 and Arg-1096 in rat MRP2 prevents the transport of TC, whereas the presence of neutral amino acids at the corresponding position of rat MRP3 is required for the transport of substrates.
