ABSTRACT:
It was study the influence of the protein level on the meat production and meat
composition in Marele Alb sows exposed at the alternative hightemperature (8 hours at
35 0 C and 12 hours at 25 0 C). The experimental period was 40 days. The two
experimental groups were fed on the izocalorice diets (3100 EM kcal/kg). At the group
1 (control) the protein level was in concordance with the feeding standardize (13%). At
the group 2 the protein level was increased with 25% (16,3%). The daily gain was 412 g
at the group 1 and 535 g at the group 2 (p≤0,05). The feed intake was 2, 085 Kg g at the
group 1 and 2,113 kg at the group 2. Comparatively with the control group percent of
protein was bigger with 7,2% and of fat with 18,5%, (p≤0,05). The negative effects of
high temperature were attenuated by the increase in protein level with 25%.
