“…According to FREITAS et al (2006), this occurs because meat quails feed primarily to meet their energy requirements, which is a similar behavior to that of broiler hens. These results are in agreement in those reported by VELOSO et al (2012), SCHERER (2011), andTON et al (2011), who observed a decrease in feed intake with the increase on ME level of in diets for meat quails at 35 days of age.…”

This experiment was conducted to evaluate the effects of dietary nitrogen-corrected apparent metabolizable energy (AMEn) levels on meat-type quail performance and carcass traits from 1 to 14d of age. A total of 1120 not sexed meat-type quails were randomly distributed to seven treatments, with eight replicates with 20 quails each. A basal corn and soybean meal-based diet was formulated to meet or exceed quail nutritional requirements, except for ME. Graded levels of soybean oil were added to the basal diet in replacement, to sand, to obtain dietary treatments (2,600; 2,700; 2,800; 2,900; 3,000; 3,100 and 3,200 KcalAMEn/kg diet). Data were analyzed as one-way ANOVA and optimum AMEn levels were estimated using polynomial regression model. Increasing in dietary AMEn levels elicited a linear decrease (p<0.01) in feed intake and nutrient intake (AMEn, protein and lysine). Quail weight gain and final body weight exhibited a quadratic response (p<0.03) to increased AMEn levels, being both optimized at 2820 KcalAMEn/kg diet. Graded AMEn levels elicited a linear increase (p<0.01) in carcass dry matter and fat content, whereas moisture content was linearly decreased (p<0.01). The protein content of the carcasses was not influenced (p>0.05) by AMEn. Based on the results, the dietary AMEn level that warrants adequate performance and carcass traits of meat-type quails from 1 to 14d of age is 2,820 Kcal/kg diet.

“…De modo semelhante, Ton et al (2011), avaliaram rações contendo níveis crescentes de energia metabolizável e não observaram efeito sobre a taxa de deposição de proteína, porém notaram aumento linear na taxa de deposição de gordura na carcaça de codornas de corte aos 35 dias de idade conforme aumentou o nível energético das rações. Entretanto, Scherer et al (2011) utilizando óleo de soja, milho e glúten de milho 60 como fonte de energia, verificaram que diferentes níveis de energia metabolizável influenciaram a taxa de deposição de proteína (TDP) nos cortes de codornas de corte, aos 14 dias de idade, enquanto a taxa de deposição de gordura (TDG) não sofreu efeito significativo. Esses resultados indicam a influência da composição nutricional da dieta sobre a composição da carcaça das aves.…”

“…A TDP e TDG foram calculadas segundo fórmulas citadas por Scherer et al (2011): TDP = (QP cf -QP ci )/PE, em que, QP cf é a quantidade, em gramas, de proteína nos cortes finais; QP ci é a quantidade de proteína nos cortes iniciais e, PE é o período experimental em dias. A QP cf foi obtida multiplicando-se o peso médio dos cortes das aves de uma unidade experimental, ao final do experimento, pela respectiva proteína bruta dos cortes (PBC); enquanto QP ci foi obtida pelo peso médio das aves da respectiva unidade experimental, ao início do experimento, multiplicando pelo rendimento médio dos cortes e pela PBC média do grupo adicional (6 pintinhos abatidas inicialmente).…”

ResumoEste estudo teve por objetivo avaliar o efeito do fornecimento de diferentes níveis de farinha de resíduos da indústria de filetagem de tilápia (FT) sobre a taxa de deposição de proteína (TDP) e gordura (TDG) no peito e nas pernas (coxa e sobrecoxa) de frangos de corte, abatidos aos 42 dias de idade. Foram utilizados 480 pintos de um dia, da linhagem Cobb, distribuídos em um delineamento experimental inteiramente casualizado, com cinco tratamentos, seis repetições e 16 aves por unidade experimental. Os tratamentos experimentais consistiram em cinco níveis (0, 2, 4, 6 e 8%) de inclusão da FT. As dietas experimentais foram isoenergéticas e isonutritivas, seguindo as recomendações de exigências nutricionais dos frangos de corte para as fases de 1 a 21 e 22 a 42 dias de idade. Não houve influência (P>0,05) dos níveis de inclusão da FT sobre a TDP e TDG no peito e nas pernas (coxa e sobrecoxa) das aves. De acordo com os resultados encontrados constatou-se que pode-se incluir até 8% de farinha de resíduos da indústria de filetagem de tilápia sem prejuízo nos parâmetros de deposição de gordura e proteína na carcaça de frangos de corte. Palavras-chave: Alimentos alternativos, composição química da carcaça, farinha de peixe AbstractThe present research was aimed to evaluate the effect of different inclusion levels of tilapia industrial filleting waste (TM) on protein (PDR) and fat deposition rate (FDR) in broilers chicken breast and legs (thigh and drumstick), slaughtered at 42 days of age. Four hundred and eighty chickens were used in a completely randomized design with five treatments, six replicates and sixteen birds per experimental unit. The treatments consisted in five inclusion levels (0, 2, 4, 6 and 8%) of TM. The experimental diets were isocaloric and isonutritives, following the nutritional requirements recommendations for stages 1 to 21 and 22 to 42 days old for broilers chickens. No influence (P>0.05) for inclusion levels of TM on PDR and FDR in the poultries breast and legs (thighs and drumsticks). According to the results, the inclusion of 8% of tilapia industrial filleting waste in broiler feeding did not affect the parameters of protein and fat deposition rate in broilers chicken carcass.

“…The experimental diets were formulated based on ground corn and soybean meal to meet the nutritional requirements, following recommendations by Scherer et al (2011) for metabolizable energy requirement; Furlan et al (2011) to meet the requirement of digestible lysine; and to meet the requirements of calcium and available phosphorus in the diet.The isonutritive diets differed only with respect to the levels of vitamin K, using ground rice huskas the vehicle (Table 1). The source of vitamin K used was Kavist® Plus from Dirox, with menadione (synthetic compound) being the compound used with a composition of 500mg of vitamin K/g.…”

The experiment was carried outto determine the levels of vitamin K for meat quails (Coturnixcoturnixsp) from 1 to 14 days of age. Atotal of 2200 birds were used, complete by random experimental design, with 8 treatments, 5 repetitions and 55 meat quails per experimental unit. The levels of vitamin K supplementation were 0; 0.7; 1.0; 1.3; 1.6; 1.9; 2.2; 2.5 mg/kg diets. The performance was measured through weighing weekly from the birds and feed, and at the end of the experiment was carried out collects blood and bones for the assessment of bone quality parameters. The levels of vitamin K supplementation had no influence on performance orbone quality, except thatthe bone density and calcium concentration of the femur and the bone density of the tibia showeda quadratic effect, with estimates of 0.98; 0.92 and 1.18 respectively. The length of the tibia showed a linear increase according to the levels of vitamin K. There was no effect in the concentration of serum calcium, but there was a quadratic effect in the concentration of alkaline phosphatase. The vitamin K supplementation did not affect the performance of the meat quails from 1 to 14 days of age, showing that the amount of vitamin K present in ground corn and soybean meal-based diets is sufficient to meet the needs of the birds' performance.
