Resumo: Feed costs in the production of broilers revolve around 60-70 %. This value varies according to the cost of each ingredient and the percentage thereof to meet the requirements of animals. In Brazil the feeding programs are used most of 3 and 04 phases. However, this system of the period the birds given below or above the nutrient requirement. A solution to this impasse is the use of feeding programs with more stages, but there are no studies evaluating the feasibility of this system in Brazil. The aim of our study animal performance, carcass and commercial cuts, body composition, nitrogen excretion and economic viability of fed birds was to evaluate according to a program of 14 stages compared to 4 phases. We used 480 broiler one day old Cobb strain. The birds were distributed in a completely randomized design in a factorial 2x2 (gender: male and female; feeding program: 4 and 14 phases). Each treatment consisted of six replicates of 20 birds each. Two premixes diets (A and B) were used, so that the diet met the requirements at the beginning of the growing period and B at the end. The pre-mixes A and B were combined to meet the requirement of lysine using a method specific formulation. Nutritional requirements were determined using the software Avinesp. The performance was evaluated for the periods 1-21, 22-42 and 1-42 days of age by means of live weight (g), feed intake (g), protein intake (g), weight gain and feed conversion. Carcass yield and commercial sections was performed at 42 days. We determined the protein deposition (g) and body fat (g), by comparison at the beginning and the end of the experimental phase slaughter. Nitrogen excretion was evaluated between 1-42 days. In economic analysis, the average weight gain and feed conversion for each treatment were combined with the costs of each diet and live weight price of economic variables to estimate food costs, gross margin and profitability. There was no interaction ...

Esse valor varia de acordo com o custo de cada ingrediente e a porcentagem dos mesmos para atender as exigências dos animais. No Brasil os programas de alimentação mais utilizados são de 3 e 4 fases. Contudo, nesse sistema parte do período as aves recebem nutrientes abaixo ou acima da exigência. Uma solução para esse impasse é a utilização de programas de alimentação com mais fases, porém não há estudos avaliando a viabilidade desse sistema no Brasil. O objetivo do nosso trabalho foi avaliar o desempenho animal, rendimento de carcaça e cortes comerciais, composição corporal, excreção de nitrogênio e viabilidade econômica de aves alimentadas segundo um programa de 14 fases comparado ao de 4 fases. Utilizamos 480 pintos de corte com um dia de idade da linhagem Cobb. As aves foram distribuídas em delineamento inteiramente casualizado em esquema fatorial 2x2 (sexo: macho e fêmea; programa alimentar: 4 e 14 fases). Cada tratamento foi constituído por seis repetições, com 20 aves por unidade experimental. Duas pré-misturas de dietas (A e B) foram utilizadas, de modo que a dieta A atendia as exigências no inicio do período de crescimento e a B no final. As pré-misturas A e B foram combinadas para atender a exigência em lisina utilizando um método de formulação especifico. As exigências nutricionais foram determinadas utilizando o software Avinesp. O desempenho foi avaliado nos períodos de 1 a 21, 22 a 42 e 1 a 42 dias de idade por meio do peso vivo (g), consumo de ração (g), consumo de proteína (g), ganho de peso e conversão alimentar. O rendimento de carcaça e cortes comerciais foi realizado aos 42 dias. Foram determinadas as deposições de proteína (g) e gordura corporal (g), por meio de abates comparativos no início e ao final da fase experimental. A excreção de nitrogênio foi avaliada no período de ...Universidade Estadual Paulista (Unesp)Hauschild, Luciano [UNESP]Sakomura, Nilva Kazue [UNESP]Universidade Estadual Paulista (Unesp)Bueno, Camila Ferreira Delfim [UNESP]2015-01-26T13:21:12Z2015-01-26T13:21:12Z2014-03-14info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisxiv, 53 p. : il.application/pdfBUENO, Camila Ferreira Delfim.
