In this work we study the growth and feed intake of male Galiña de Mos breed to reach the socalled minimal commercial weight stipulated by many authors and the market at around 2.1 kg weight, in two different seasons of the year, winter and spring, compared with a blonde chicken strain commonly used in Galicia, Sasso T-44. A hundred and thirty male, sexed, chicken T-44 and 400 Mos chicken unsexed (until to 4 weeks of age, when males were separated for the study) were raised in the Centro de Recursos Zooxenéticos de Galicia under extensive conditions. It was observed a significantly higher feed intake, both in the native breed and the industrial hybrids, in chicken reared in winter compared to those of spring, due to the influence of different temperatures observed. There were no major differences in the age at which reached 2.1 kg weight, since Mos's reached the 87 and 89 days in spring and winter respectively and 68 and 70 days in the T-44.

There were analyzed the physico-chemical properties and the profile of amino acids and fatty acids found in lambs of the Ovella Galega breed fed solely on their mother's milk and slaughtered at 45 days. The results show a low percentage of intramuscular fat (0.62%) and lower-middle hardness (4 kg/cm2). The amino acids' profile is similar to that of a high quality protein. Concerning the fatty acids' profile, the study shows a high percentage of unsaturated (55%), both mono and polyunsaturated, versus a lower percentage of the saturated ones (44.82%), apart from a well proportioned ratio ω6/ ω3, (1,88).

The Ovella Galega is a endangered sheep breed and is protected by a Conservation and Recovery Programme, in order to keep the genetic variability. A growth and carcass study was made on Ovella Galega lambs, whose main objetive is its characterization. Ten male lambs from single birth and fed solely on their mother's milk, all of them registered in the Record of Births of Stud-Book, were slaughtered at 45 days old. The growth and average dayly gain are in accordance to results published in other breed studies. The results show a high commercial yield (59%), apart from appropriate percentages in 1st and 2nd market categories.
