In the first experiment, the chemical composition, apparent metabolizable energy (AME), AME corrected for nitrogen (AMEn), true metabolizable energy (TME), TME corrected for nitrogen (TMEn) values of the sweet almond meal were determined in adult Leghorn cockerels. The second experiment was performed to evaluate the effects of different levels of sweet almond meal at 0, 100, 200 and 300 g/kg on Japanese quail's growth performance, some blood metabolites, relative weight of different organs, meat quality and egg yolk cholesterol in a completely randomized design with 288 Japanese quails including 4 treatments, 4 replicates and 18 birds per replicate. The metabolizable energy values of sweet almond meal were following: AME = 3734, AMEn = 3648, TME = 3908, TMEn = 3746 kcal/kg as fed basis. Feed intake, feed conversion ratio and live weight gain and relative weight of different organs in the birds fed diets with different levels of the sweet almond meal were not statistically different from control. A sweet almond meal at 300 g/kg level showed the lower serum total cholesterol and low-density lipoprotein (P < 0.05) compared to control and 100 g/kg sweet almond meal. Dietary treatments had no significant effect on the total cholesterol content of quail's eggs. Malondialdehyde concentration in breast meat samples after 40 days freezing decreased, whereas the level of sweet almond meal increased (P < 0.01). In general, a sweet almond meal without any adverse effect on growth performance is a good source of energy and protein and can be used up to 300 g/kg of the Japanese quail diets.

Realizou-se este estudo com o objetivo de verificar o efeito do nível energético da ração e da suplementação com cloretos de potássio e de amônia na dieta de frangos de corte no verão. Foram utilizados 240 frangos machos, Hubbard, com peso médio inicial de 1204 g, distribuídos num delineamento inteiramente casualizado, em esquema fatorial 2 x 3 x 2, 2 níveis de KCl (0,0% e 1,2%) x 3 níveis de NH4Cl (0,0%, 0,2% e 0,4%) x 2 níveis de energia (3000 e 3200 Kcal EM/kg de ração), com 4 repetições de 5 aves por repetição. O índice de temperatura do globo negro e umidade (ITGU), observado às 9 horas e 15 horas foi de 76 e 83, respectivamente. Houve interação (P0,05) dos fatores estudados. A ingestão de água aumentou (PTwo hundred and forty male chickens with weight means initial of 1204 g, were utilized and allocated according to a completely randomized design , with treatments arranged in a factorial scheme 2 x 3 x 2, 2 2 levels of KCl (0,0% and 1,2%) x 3 levels of NH4Cl (0,0%, 0,2% and 0,4%) x 2 levels of Metabolizable Energy (3000 and 3200 Kcal ME/kg of diets), with four replications with five broilers in each. The index of temperature of the black globe and humidity (ITGU) was observed at 9:00 and 15:00 hours which was of 76 and 83, respectively. There was a significant interaction (P 0,05) by the treatments studied. The water intake increased (P
