VALBUENA-VILLARREAL, Rubén Darío; ZAPATA-BERRUECOS, Beatriz Elena  y  ROSADO-PUCCINI, Rafael. Characterization of the Protein, Lipid, Energy and Fatty Acid Profile Composition in Red Tilapia (Oreochromis spp.) eggs. Rev. Med. Vet. [online]. 2013, n.25, pp.39-47. ISSN 0122-9354.

After considering the meaning of tilapia in the national piscicultural scenario, the possibility of improving production rates is a technical imperative and, among these, focusing experimental efforts in the seed turns out to be a strategic option. In order to establish a base model, individual laying of 50 female red tilapia (Oreochromis spp.) were used to determine the content of protein in eggs (%MS), ether extract (%DM), energy (cal g-1) and fatty acid profiles (%) with some relations of analytical interest. Except for minor variations, the values found are consistent with the available records for the species in different studies, suggesting that diets offered to experimental breeders contain the minimum necessary to ensure provision of sufficient energy and nutrients for embryos and larvae in formation. It is analyzed that, as a starting point, this series of data is useful for the development of work to improve the standards of fingerling production, considering that variations in the composition, which can be determined on the eggs, can be used and have validity as a direct indication of its quality.

Palabras clave : Egg quality; egg composition; Oreochromis spp.; red tilapia.
