“…Its inclusion at levels up to 150 g/kg in finishing pig diets showed effects on nutrient digestibility reducing GE and increasing NDF-and ADF-CTTAD; however, the digestibility of GE was acceptable up to 100 g inclusion/kg of diet. These results are in agreement with those reported in the literature (Baird et al, 1974;Galassi et al, 2004;Watanabe et al, 2010a;Ruiz et al, 2012) in which the inclusion of dried citrus pulp or other pectinrich feedstuff such as sugar beet pulp lowered nitrogen (N) and EE digestibility but significantly increased fibre digestibility. Also Rijnen et al (2001) found increased fibre digestion in sows fed diets with sugar beet pulp silage.…”

“…In the present study, digestible protein of ECP was low (33.8 g/kg of DM), but this was expected since the mean CP content of citrus by-products is generally low and often linked to fibre (Gasa et al, 1992). On the other hand, Watanabe et al (2010a) reported digestible protein contents even lower for dried citrus pulp (8.9 g/kg of DM), thus indicating that the ensiling process could increase the availability of the inherent low digestible protein of fruits. Overall, in terms of nutritive value, ECP seems a low valuable feedstuff in pig nutrition.…”

“…Also Rijnen et al (2001) found increased fibre digestion in sows fed diets with sugar beet pulp silage. The fibre fraction of the ECP in this study was highly digestible and above that of other more lignified feed ingredients, which is due to its high pectin and soluble fibre content (Watanabe et al, 2010a). In fact, the NDSF fraction determined in this study for ECP was relatively high compared to that given for other feedstuffs such as sorghum DDGS (Cerisuelo et al, 2012) and corn DDGS (Stein & Shurson, 2009).…”

“…O'Sullivan et al (2003) estimated the digestible energy value of dried citrus pulp for growing pigs to be 12.0 MJ/kg of DM. Watanabe et al (2010a) reported digestible energy values for dried citrus pulp to be around 10.4 MJ/kg of DM). Both values are lower than those reported for most cereals used in animal nutrition.…”

Ensiled citrus pulp as a by-product feedstuff for finishing pigs: nutritional value and effects on intestinal microflora and carcass quality

Forty pigs of 76.8 ± 4.2 kg body weight were fed four different diets varying in ensiled citrus pulp (ECP) inclusion level (0, 50, 100, and 150 g of ECP/kg of diet on dry matter base). The trial lasted 5 weeks. During the last week, faecal samples were obtained to calculate apparent nutrient digestibility; also volatile fatty acids (VFA) content in faeces was determined. The digestible energy and protein of ECP was estimated by regression analysis. During the trial faecal samples were collected to determine enterobacteria and lactobacilli counts. At slaughter, carcass characteristics were registered. The inclusion of ECP in the diets decreased energy digestibility but increased neutral and acid detergent fibre digestibility linearly (p<0.05). The estimated digestible energy and protein of ECP were lower than expected (7.0 MJ/kg dry matter (DM) and 33.8 g/kg DM, respectively). Total VFA production in faeces was not affected by the diet. Both enterobacteria and lactobacilli counts were lower (p<0.01) with than without ECP inclusion at the end of the study. Carcass yield decreased linearly (p<0.05) and backfat at gluteus medius increased quadratically (p<0.05) with the inclusion of ECP in the diet. The polyunsaturated fatty acid content of the internal subcutaneous fat layer decreased quadratically (p<0.05) with the inclusion of ECP. Thus, the nutritive value of ECP for finishing pigs is low and levels of 150g/kg can negatively affect carcass yield. However, including up to 100 g of ECP/kg in finishing pig diets did not affect nutrient digestibility, carcass yield and subcutaneous fat FA profile. Additionally, increasing ECP levels in diets decreases faecal enterobacteria and lactobacilli counts in faeces.Additional key words: agroindustrial by-products; digestibility; gut microbiology; carcass performance.

“…In relation to diets containing citrus pulp, the reduction in daily feed intake, the worse weight gain and feed conversion can be justified by low palatability of the ingredient to swine, as stated by Watanabe et al (2010) when using citrus pulp in the diets of finishing pigs.…”

Dietary fiber is an important component, which has a direct effect on intake, digestion, and absorption of nutrients; and also alters intestinal microbiota and morphology according to solubility. One digestibility trial and one performance experiment were performed to evaluate the effects of sources of fiber in diets for 21 day weaned piglets. The experimental diets used in both trials consisted of a control diet and diets with purified cellulose, soybean hulls or citrus pulp as a main source of dietary fiber. To evaluate the digestibility of nutrients (Assay 1), the total feces and urine collection method was used. The fiber sources did not affect nutrient digestibility, except for soluble fiber, which increased with the inclusion of citrus (Citrus sinensis L.) pulp. To evaluate performance, morphophysiology and microbiology of the digestive tract of weaned piglets, a total of 32 castrated male piglets was used. Slaughter of animals was implemented at 35 and 50 days of age. The use of soybean (Glycine max L.) hulls and citrus pulp in diets increased the number of goblet cells and the density of villi in the jejunum. The viscosities of stomach and cecum contents increased due to the addition of citrus pulp. Soybean hulls and the citrus pulp included in diets reduced the occurrence of E. coli in the small intestines of piglets slaughtered at 35 days of age. Among the fiber sources, purified cellulose in piglet diets promotes better performance of animals, due to the modulation of the small intestine microbiota, with lower E. coli occurrence resulting in higher villus density.
