“…Although no difference has been detected in some cases (Santos et al, 2007;Pires et al, 2008), studies involving lactating cows have found advantages of fine grinding over coarse grinding (Nussio et al, 2002;Dhiman et al, 2002).…”

The objective was to assess the effects of a concentrate consisting of two types of corn: flint and dent, with three different grinding degrees (1, 3 and 5 mm), as a function of intake, performance and digestibility of three crossbred dairy suckling heifers. A randomized block design involving 54 crossbred heifers in a 2 × 3 factorial arrangement was used to assess intake and performance patterns. In order to assess digestibility, the experimental design was completely randomized, consisting of 24 crossbred heifers. Weighting and measurements of height at withers and thoracic perimeter were performed. There was no significant interaction between grinding degree and corn type for any of the studied variables. The daily intake of concentrate dry matter was higher for flint corn (243 g/day) as compared with dent corn (160 g/day). The grinding degree caused difference in the dry matter, crude protein and ether extract intake, with higher intake when 3 and 5 mm sieves were used in the process. There was no difference regarding average daily gain and increased withers, croup and thoracic perimeter. Likewise, feed conversion did not differ. Regarding dry matter digestibility, there was an effect resulting from the hardness of corn (78.9% for dent, and 84.3% and for flint corn). As for the grinding degree, the highest value of dry matter digestibility was found when using 5 mm sieves (84.2%), whereas the percentage values found for 1 mm and 3 mm mesh sieves were 79.1% and 78.1%, respectively. It is recommended that heifer calves in the early stage of growth be fed flint corn ground through 3 or 5 mm mesh sieves

“…A polpa cítrica apresenta em sua composição cerca de 25% de pectina (Muller & Prado, 2004a, 2004b. A pectina é um carboidrato estrutural, componente da fração solúvel da fibra, sendo esta um polímero de ácido galacturônico (Santos et al, 2007). Segundo, Domínguez (1995), a pectina tem a capacidade de se ligar aos ácidos biliares, aumentando sua excreção e reduzindo o pool entero-hepático de colesterol circulante (Montagne et al, 2003;Silva et al, 2003).…”

A produção de citrus é a cultura mais abundante no mundo, constituída pela industrialização de laranjas, limões, toronjas e mandarins, que representam aproximadamente 98% de toda a cultura industrializada; as frutas cítricas são processadas principalmente para a obtenção de suco, e também na indústria de conservas, de este processo se produz a polpa de citrus que compreende aproximadamente 45 a 58% do total da fruta. A polpa de citrus está composta por cascas, membranas e sementes. Assim, o subproduto de polpa cítrica, pode ser utilizado para diminuir os custos da produção animal, além de reduzir o impacto ambiental do descarte indevido desses resíduos, devido a seu alto valor nutricional que o caracteriza como alimento de alta energia e com propriedades melhoradoras da saúde intestinal, qualidade do produto final, da oxidação e dos parâmetros produtivos.

“…On the other hand, citrus fruit pulp has lower NDF content and protein when compared with SBH. Based on DM, Santos et al (2007) recorded 9.17, 6.90 and 11.96% CP; 6.12, 23.41 and 63.79% NDF; 1.22, 15.76 and 46.27% ADF; and 73.39, 0.5 and 3.6% starch, for corn, citrus fruit pulp and soybean hulls, respectively. Rodrigues et al (2008a) found that the substitution of one third of the maize by citrus fruit pulp improved the dry matter intake and performance of lambs fed with this concentrate.…”

Owing to the magnitude and importance of the production of citrus fruits pulp, soybeans and corn in Brazil, considerable research has focused on the main feedstuffs, co-products, and/or byproducts of these crops. The present study is aimed at comparing the ruminal degradability parameters of corn and non-starchy energy sources with high pectin content, including soybean hulls and citrus pulp, through meta-analysis. The experiments were designed to include parameters related to potential and effective degradability of the concentrates of these energy feeds. The database (DB) was composed of 62 treatments obtained from 20 papers. No difference (P>0.05) was observed in any of the ruminal degradability parameters of the dry matter (DM) or crude protein (CP), demonstrating that the total replacement of corn grain by non-starch feed is possible. The degradation rates of DM were 6.78 and 6.14%.h-1 and those of CP were 5.97 and 5.93%.h-1 , for corn and non-starch feeds, respectively. Therefore, depending on the cost, corn grain could be substituted by soybean hulls or citrus pulps, which reduce the possibility of the occurrence of metabolic disorders, such as subclinical and/or clinical acidosis, without affecting ruminal fermentation.
