Non-linear models to describe consumption, nutrient deposition in the body and growth of Saanen x Alpina kids

espanolObjetivou-se avaliar o consumo de nutrientes em cabritos alimentados com leite de cabra variando em concentracao de gordura (24,2; 34,4; 44,3; 65,6; e 82,1 g kg-1 MS) para estudar seu efeito no desempenho e na conversao alimentar, durante o aleitamento e pos-aleitamento, em um delineamento inteiramente casualizado em esquema fatorial, com 12 repeticoes por dieta liquida inicialmente. O periodo experimental iniciou o dia setimo de vida, com 60 cabritos da raca Saanen e Alpina confinados em gaiolas de metabolismo individual, recebendo 1,5 L/Leite/dia divididos em duas refeicoes 08h00 e 15h00 ate os 15 dias de vida; do dia 16 ate o dia 52 de vida foi oferecido 2L/Leite em duas refeicoes, a partir do dia 53 e ate o dia 67 de vida os animais comecaram a receber 1L/Leite na parte da tarde; sendo que, a partir do dia 37 ate o dia 195 de vida foi fornecido capim-Tifton-85 (Cynodon dactylon) ad libitum e 10 g/kg PV de racao concentrada para cada animal. Foi realizado um abate referencia aos sete dias de vida e quatro abates ao longo do experimento: 37, 67, 142 e 195 dias de vida. Todos os procedimentos estatisticos foram programados no SAS (9.0) atraves do PROC NLIN adotando 0,05% de probabilidade para o erro Tipo I.

The experimental period began on the seventh day of life, with 60 Saanen and Alpina goats confined in individual metabolism cages, receiving 1.5 L / Milk / day divided into two meals at 08:00 and 15:00 until 15 days of life; From day 16 to day 52 of life was offered 2L / Milk in two meals, from day 53 and until day 67 of life the animals began to receive 1L / Milk in the afternoon; And from day 37 to day 195 of life Tifton-85 (Cynodon dactylon) ad libitum grass and 10 g/kg PV of concentrated feed were supplied for each animal. A slaughter reference was made to the seven days of life and four slaughterings during the experiment: 37, 67, 142 and 195 days of life. All statistical procedures were programmed in the SAS (9.0) through PROC NLIN adopting 0.05% probability for the Type I error. There was a difference (P
