The aim of this study was to evaluate the effects on feed intake, heifer performance, and health of increasing the total solids (TS) content of liquid feed (whole milk) by adding increasing amounts of milk replacer powder during the pre- and postweaning periods. Crossbred Holstein-Gyr heifers (n = 60) were assigned to 1 of 4 treatments (n = 15 per group), which consisted of different TS concentrations: 12.5, 15.0, 17.5, and 20.0% of liquid feed. Heifers received 6 L of liquid feed per day, divided into 2 equal meals (0800 and 1600 h) and provided in buckets, from 5 to 55 d of age. From 56 to 59 d of age, the total amount of liquid feed was reduced by half, maintaining only morning feedings. Heifers were weaned at 60 d and monitored until 90 d of age. Water and starter were provided ad libitum during the entire experiment. Corn silage was included in the diet during the postweaning period (70 d of age). Feed intake and health scores were evaluated daily. Body weight and body frame development were recorded weekly. Starting at 14 d, ruminal pH was measured every other week. Laboratory analysis determined that the actual TS contents of the liquid feed were 13.5, 16.1, 18.2, and 20.4%, for the proposed 12.5, 15.0, 17.5, and 20.0% TS treatments, respectively. The osmolality of liquid feed treatments was 265 to 533 mOsm/L. Intake of liquid feed was similar among treatments from 4 wk of age. During the preweaning period, starter intake, fecal score, and days with diarrhea were similar among treatments. Ruminal pH at weaning averaged 6.2 and was similar among treatments. Increasing concentrations of TS in the liquid feed were associated with linear increases in average daily gain, final body weight, and growth performance, but linear decreases in feed efficiency. During the postweaning period, intake of starter, corn silage, and water were similar among treatments, as well as average daily gain and feed efficiency. Final body weight and growth performance during the postweaning period also increased linearly with concentration of TS in liquid feed. Increasing the concentration of TS in liquid feed up to 20.4% increased performance and body frame development in dairy heifers during the pre- and postweaning periods and had no effects on solid feed intake or health.

O interesse pelo estudo da cadeia produtiva de produtos de caprinos no NE brasileiro encontra-se incrementado atualmente pela tomada de consciencia sobre a contradicao que supoe situar-se em uma regiao vocacionada para a atividade e por estarem desarticulados a maioria dos seus segmentos, ofertando produtos com frequencia irregular, a precos elevados e com qualidade que nao satisfaz as expectativas do mercado domestico. No intuito de sistematizar informacao sobre um dos segmentos da referida cadeia produtiva, este trabalho busca identificar as relacoes economicas existentes e seus pontos criticos relevantes entre alguns estocadores de peles caprinas no Estado do Ceara. Atraves de uma matriz de dados oriunda de pesquisa de campo direta em quatro municipios, elaboraram-se varios indicadores micro-economicos a partir de variaveis mercadologicas. A empresa 4 apresentou os melhores resultados economicos ao atingir a melhor produtividade especifica da pele, atraves da nao utilizacao de deslocamento devido a compra de materia-prima associada a uma area de abrangencia municipal e distrital. [Skins goat market efficency in Northeast of Brazil: comparative study of stock units in Ceara State]. Abstract: The interest in studying the commercial chain of goat products in northeast of Brazil is increased now by the knowledge over the contradiction that this region is devoted for goat production, and because the majority of its chains are disjoint, offering products without frequency, with high prices and low quality, which is against the domestic market. The objective of this study was to identify the economical relationships and theirs main critical points among some stocking units of goat skins in Ceará State. Several microeconomic indicators were determined from market variables by using a matrix with data collected in four counties. The enterprise 4 showed the best economic results with high specific productivity, because it does not use displacement to buy commodities in its type comprising area.
