“…The feed sample was also characterized for its carbohydrates fractions and fat content (Le Goff and Noblet, 2001;Le Gall et al, 2009). Apparent digestibility coefficients of DM, organic matter, nitrogen and energy were calculated for each pig at each period according to standard procedures (Le Gall et al, 2009). These digestibility coefficients were also calculated for each pig for the total 10-week experimental period as the weighted mean of the weekly digestibility coefficients, weights being the corresponding DMIs for each week.…”

“…Variations in diet composition, feed technology, animal development (BW) or animal breed can impact digestibility coefficients of nutrients and energy (Le Gall et al, 2009). With regard to breed effects, comparing Asian breeds with commercial European lines in pig has generally shown that commercial European lines have a lower digestive efficiency than Asian populations, especially when given fibrous feeds (Kemp et al, 1991;Fé vrier et al, 1992;Morel et al, 2006;Len et al, 2009a).…”

Energy digestibility in the growing pig increases with BW increase and may differ between breeds of pigs or between lines selected on criteria other than digestion. However, little is known about the variability in energy digestibility within a line or a breed of pigs, especially when fibrous diets are fed. For this purpose, 20 Large White castrated male growing pigs originating from four boars (five per boar), and three to four sows per boar, were fed a high dietary fibre (DF) diet (18% NDF) and measured over 10 consecutive weeks (30 to 95 kg BW range) for their apparent faecal energy, nitrogen and organic matter digestibility. Each week, faeces were totally collected over 5 days and the feed dry matter intake over the same days was recorded. All digestibility coefficients increased regularly ( P , 0.001) over the experimental periods or with BW increase (10.6 point/10 kg BW increase for energy); this rate of increase was not affected by boar origin (no interaction; P . 0.05). The digestibility coefficients were affected by boar origin ( P , 0.005 for energy), with about 2 points for energy between the extremes (81.7% v. 79.5%), and there was no marked interaction between boar origin and period. These preliminary results suggest the possibility of selecting growing pigs for an increased digestive efficiency when fed high DF diets.Keywords: growing pig, digestibility, genetic variability, BW, dietary fibre ImplicationsOur study suggests that growing pigs can be selected for improved nutrients and energy digestibility, especially if fed on a high dietary fibre diet. This study also confirms the increase in energy digestibility with BW increase; this increase would be independent on genetic background. A single digestibility measurement carried out at 60 to 70 kg BW would be representative for evaluating genetic differences in energy digestibility in growing-finishing pigs. The mechanisms involved in the genetic differences of digestion (microbiote, genomics, gut structure and physiology, etc.) deserve further studies. Routine methods for evaluating the digestibility on large numbers of pigs should also be proposed.

“…Fibre levels in maize cobs should be reduced to improve their nutritive contribution to pig diets. Fermentation and the use of exogenous enzymes and acids have been reported to reduce fibre content of maize cobs (Latif & Rajoka, 2001;Le Gall et al, 2009;Urriola et al, 2010;Zhang et al, 2010a). However, the use of acids to decrease fibre is unattractive because of safety, and environmental and economic concerns.…”

The study was conducted to assess the effects of whey, molasses and exogenous enzymes on fermentation, aerobic stability and nutrient composition of ensiled maize cobs. Five treatments were ensiled in 1.5 L anaerobic glass jars over 32 days, namely i) control (maize cobs without additives (CON); ii) maize cobs with sugarcane molasses only (MOL); iii) MOL and whey (MOW); iv) MOW and exogenous enzyme at 0.5 g/kg maize cob mixture (ENZ1) and v) MOW and exogenous enzyme at 1 g/kg maize cob mixture (ENZ2). There was a day effect on gross energy (GE) for CON, MOL, ENZ1 and ENZ2 and none for MOW. There was a day effect in ADF for MOL, ENZ1 and ENZ2 and none for CON and MOW. There was lower dry matter (DM) on day 32 compared with day 0 for all treatments. There were treatment effects for GE, crude protein (CP), ash, ether extract, amylase-treated neutral detergent fibre and acid detergent fibre (ADF). On day 32, the neutral detergent fibre (NDF) and ADF concentrations in CON were higher than in MOL, MOW and ENZ2. At day 32, CON silage pH (4.2) was lower than the pH values of ENZ1 (4.5) and ENZ2 (4.6) silages. Acetic acid levels were higher in ENZ1 than ENZ2 silages. Ammonia nitrogen (NH 3 -N) levels averaged 25 ± 6.6 g NH 3 -N/kg total nitrogen, which is indicative of satisfactory ensiling. The MOL, ENZ1 and ENZ2 silages produced more carbon dioxide than CON and MOW silages. The addition of molasses and whey did not improve the nutritive quality of the maize cobs after ensiling. Ensiling maize cobs with molasses, whey and exogenous enzymes resulted in lower DM and fibre levels in the maize cobs, which could enhance intake and digestibility of nutrients when offered to pigs as a component of a balanced diet. Further investigations using higher concentrations of whey and molasses are warranted to improve the energy and protein composition of the maize cobs. ______________________________________________________________________________________

“…The nitrogen in feeds, digesta and urine was assayed by the method AFNOR NF V18-120 (AFNOR, 1997). In addition, casein, leaf and diet samples were analysed for ash, starch, crude fat, crude fibre, neutral detergent fibre (NDF), acid detergent fibre, acid detergent lignin (Van Soest et al, 1991) and gross energy (IKA adiabatic bomb calorimeter) according to the methods listed by Le Gall et al (2009). Digesta samples were also analysed for their ash and gross energy values.…”

Ileal digestibility in growing pigs fed starch-based diets with inclusion of four tropical leaves in a meal form was studied in a 5 3 5 Latin square design. Five diets were formulated with only casein as protein source in the basal diet (CAS), and casein plus dry cassava (CA) leaves, casein plus dry sweet potato (SP) leaves, casein plus dry cocoyam (CO) leaves and casein plus erythrina (ER) leaves in the other four diets. All diets contained the same amount of CP (14%), either provided by only CAS or a combination of casein and 250 g of leaf meal per kg of diet in the other diets. Leaves were separated manually from stems, and only the leaf part was used. A protein-free diet was fed during a sixth period in order to estimate the endogenous protein losses and calculate the CP-and amino-acid (AA)-standardized ileal digestibility (SID) values. The values for the foliages were calculated according to the difference method, assuming no interaction between the foliage and the casein. The ileal tract apparent digestibility of CP, organic matter and energy was higher in diet CAS than in the other diets (P , 0.05). The SID of CP and AA was close to 0.950 for casein, whereas the SID of AA was markedly lower in the foliages; the SID of indispensable and dispensable AA was highest in CO (0.500 and 0.352) and lowest in ER (0.170 and 0.195); intermediate values were obtained for SPs (0.367 and 0.349) and CA (0.232 and 0.242) leaves. Accordingly, the SID of lysine was highest (0.538) for CO leaves and lowest (0.126) in ER leaves; intermediate values were measured for CA and SP leaves. These low SID values in foliage meals must be related to the high levels of dietary fibre and the presence of secondary metabolites (tannins). These results suggest that it is only possible to replace a fraction of the conventional protein sources such as soyabean meal by tropical foliages in growing pig diets with a preference for CO leaves.
