Última Modeling energy utilization in broiler breeders, laying hens and broilers Rev. Bras. Ciênc. Avic. Sakomura,NK. The factorial approach has been used to partition the energy requirements into maintenance, growth, and production. The coefficients determined for these purposes can be used to elaborate energy requirement models. These models consider the body weight, weight gain, egg production, and environmental temperature to determine the energy requirements for poultry. Predicting daily energy requirement models can help to establish better and more profitable feeding programs for poultry. Studies were conducted at UNESP-Jaboticabal to determine metabolizable energy (ME) requirement models for broiler breeders, laying hens, and broilers. These models were evaluated in performance trials and provided good adjustments. Therefore, they could be used to establish...

Almeida,Amélia Katiane de; Resende,Kléber Tomás de; Silva,Simone Pedro da; Soares,Diogo da Costa; Fernandes,Márcia Helena Machado da Rocha; Teixeira,Izabelle Auxiliadora Molina de Almeida. The objective of this study was to determine the protein requirements for the growth of intact male, female, and castrated male Saanen goats weighing 30 to 45 kg of body weight (BW) and to compare estimates of the protein requirements for maintenance (NPm) by the comparative slaughter and nitrogen balance techniques. To determine the maintenance requirements, 55 goats were assigned in a split-plot design using a 3 × 3 factorial arrangement (three sexes and three dry matter intake (DMI) levels). A linear regression of retained N (as measured by the slaughter technique and estimated from the nitrogen balance) on N intake on a daily basis was used to calculate the net protein for maintenance. The net protein requirement for weight gain (NPg) was obtained... Tipo: Info:eu-repo/semantics/article Palavras-chave: Comparative slaughter; Dairy; Factorial approach; Maintenance; Nitrogen balance.
