“…The nutritive value of citrus pulp is derived from its concentration of nitrogen-free extract (73%), sugar (14%) and pectins (Kirk and Davis, 1954;Bhattacharya and Harb, 1973). Trials on native pasture have shown that citrus pulp is a palatable feed that can be fed all year (Kirk and Davis, 1954).…”

“…(1964) found no significant differences in dry matter or crude fiber digestibilities when feeding soybean hulls with hay in varying ratios (1:1, 2:1 or 3:1). In a digestion trial with lambs, crude fiber digestibility increased (from 52% to 67%) with increased quantities of citrus pulp substituted for corn in the ration, suggesting that citrus pulp fiber does not possess the negative associative effects associated with corn (Bhattacharya and Harb, 1973).…”

“…A polpa cítrica peletizada é utilizada na alimentação de ruminantes, por sua vantagem econômica em substituir parcialmente ou totalmente o milho, especialmente em rações para cordeiros (Bhattacharya & Harb, 1973;Martinez & Fernández, 1980;Rodrigues et al, 2008a).…”

trans-11). Não houve alteração na concentração total de ácidos graxos saturados, monoinsaturados e poliinsaturados.Entretanto, a quantidade de gordura intramuscular do longissimus dorsi diminuiu com o aumento de polpa cítrica na ração, sem alterar os teores de umidade, proteína e cinzas. A substituição do milho por polpa cítrica na ração modifica a quantidade e o perfil de lipídios do músculo longissimus dorsi de cordeiros.Palavras-chave: co-produtos, ácido linoleico conjugado, ovinos, pectina, Santa Inês Fatty acids profile and chemical composition of longissimus muscle of lambs fed citrus pulpABSTRACT -The objective of this study was to determine the effects of replacing corn by dried citrus pulp on chemical composition and fatty acids profile in longissimus dorsi muscle of thirty-two Santa Ines lambs, slaughtered at average weight of 33 kg at 141 days of age. Lambs were fed a 90% concentrate (ground corn and/or dried citrus pulp, soybean meal and minerals) and 10% coastcross hay (Cynodon spp) diet. Dried citrus pulp was added at 23.7, 46.1 and 68.4% of dry matter replacing corn by 33, 67 and 100%, respectively. Total replacement of corn by dried citrus pulp resulted in 177% increase in linolenic acid concetration (C18:3) while a partial replacement showed 72% increase in conjugated linoleic acid (C18:2 cis9 trans11). There was no change in total saturated, monounsaturated and polyunsaturated fatty acids concentration. However, the intramuscular fat content of longissimus muscle decreased as dried citrus pulp increased in the diet, with no effect on moisture, protein and mineral percentage. The replacement of corn by dried citrus pulp in the rations changes the quantity and profile of lipids in longissimus muscles of lambs.

“…Alguns trabalhos ainda demonstraram redução no nitrogênio retido como o aumento da participação da polpa cítrica na ração (Bhattacharya & Harb, 1973;Pascual & Carmona, 1980). Apesar da divergência entre os trabalhos, a ausência de efeito sobre o metabolismo de nitrogênio neste estudo somente enfatiza a boa capacidade da PCUD ser armazenada em forma de silagem, além de substituir parcialmente a PCD.…”

Desempenho, características da carcaça, digestibilidade aparente dos nutrientes, metabolismo de nitrogênio e parâmetros ruminais de cordeiros alimentados com rações contendo polpa cítrica úmida semidespectinada e/ou polpa cítrica desidratada Performance, carcass characteristics, apparent digestibility of nutrients, nitrogen metabolism and ruminal measures of lambs fed diets containing wet low pectin citrus pulp and/or dried citrus pulp ABSTRACT -The objective of this study was to determine the effects of partial replacement of dried citrus pulp (DCP)by wet low pectin citrus pulp (WLPCP), wet low pectin citrus pulp silage (WLPCPS) or wet low pectin citrus pulp silage with sodium benzoate (WLPCPS+B) on performance and carcass characteristics, apparent digestibility of nutrients, ruminal measures, and nitrogen metabolism of lambs. In the performance trial, 64 Santa Inês ram lambs were fed 95% concentrate and 5% sugarcane bagasse diets during 56 days. The experimental design was a randomized complete block (RCB). The control diet contained 69.5% DCP, while in the other treatments fresh or ensiled WLPCP replaced DCP by 30% on a DM basis.There were no differences in DMI, ADG or carcass characteristics. However, feed efficiency was greater for lambs fed WLPCP compared with lambs fed DCP. In the digestibility trial, 16 Santa Inês ram lambs, canulated in the rumen, were assigned to a RCB design. Animals were fed diets containing 85% of concentrate and 15% of sugarcane bagasse. The control diet contained 75.3% DCP. A portion (30%) of the DCP DM was replaced by WLPCP, WLPCPS or WLPCPS+B. There was no difference in DM, organic matter or crude protein apparent digestibilities, except for neutral detergent fiber digestibility. Additionally, ruminal ammonia concentration was higher in diets containing DCP compared with WLPCPS and WLPCPS+B. Nevertheless, no effects of treatments were seen on the other ruminal measures. Fresh or ensiled WLPCP can partially replace DCP in rations with high level of concentrate for feedlot lambs.
