“…However, there was a noticeable increase in N retention in both breeds as N intake increased, indicated by regression analysis which never deviated from linearity, even in Cinta Senese. The lower N utilization of Cinta Senese compared to Large White is in accordance with studies by Acciaioli et al (2003) and studies by Freire et al (1998) with Alentejano (another local breed) compared to modern genotype pig.…”

“…This discrepancy can be due to the fact that in the latter trial pigs of the two breeds were coetaneous, while in the present one they had the same weight and consequently Cinta Senese pigs, being older than Large White, could have improved their digestive ability. As concerns other local pigs, Freire et al (1998) found that new weaned piglets of Alentejano breed had higher TTAD for some dietary components (fat and acid detergent fibre) than Large White ones but the wide difference in age with the subjects of the present study does not allow to draw a comparison. On the other hand, Morales et al (2002), on barrows of 88 kg of body weight, found higher apparent digestibility for organic matter in Landrace than in Iberian breed whereas no difference was found for crude protein.…”

“…On Cinta Senese, a local breed of Tuscany, Sirtori et al (2010) reported that 100 g/kg of dietary protein can be used beyond 70 kg of body weight. On the contrary, relevant studies on digestibility and nitrogen balance are scarce: for instance, Freire et al (1998) studied the digestive capability of new weaned Alentejano piglets in comparison with Large White whereas Acciaioli et al (2003) investigated the digestive utilization and nitrogen balance of field bean in Cinta Senese pig, however, no information on modulation of dietary protein content in local pigs are available.…”

a b s t r a c tThe work aimed to study the digestive capacity and nitrogen balance of Cinta Senese pig fed diets with different crude protein (CP) content. Twelve castrated male pigs (6 Cinta Senese and 6 Large White), of the same body weight (on average 62.7 kg), were submitted to 8 subsequent trials of total tract digestibility and nitrogen balance. The pigs were kept in metabolism cages allowing collection of faeces samples and total urine. The diets, of exclusive vegetal origin, were formulated to contain four protein levels 70, 100, 130 and 160 g/kg as fed (named CP7, CP10, CP13 and CP16, respectively) assured mainly by soybean meal. Total tract nutrient apparent digestibility did not differ (P>0.05) between breeds. Apparent digestibility of CP increased (P<0.01) with increasing dietary CP (from 0.756 to 0.874 for Cinta Senese and from 0.742 to 0.868 for Large White), as consequence of faecal endogenous nitrogen which underestimates the digestibility of protein in inverse proportion with its amount in the diet. Nitrogen balance showed that breed differences (P<0.01) emerged for the urinary N and the total excreted N, with higher emission in Cinta Senese than in Large White breed. The difference was not significant at CP7 diet (excreted N: 19.4 vs. 17.1 g/d for Cinta Senese and Large White) but became progressively more important (P<0.01) in the diets with higher CP content (excreted N at CP16 diet: 39 vs. 35.4 g/d for Cinta Senese and Large White). Consequently, Large White retained more nitrogen than Cinta Senese (about +2.6; +3.0; +3.4; +3.8 g/d with CP7; CP10; CP13; CP16 diet, respectively; P<0.01). So, the efficiency of N utilization (retained N/absorbed N), favoured the Large White in all the tested diets (P<0.01). These results suggest to limit the CP content in diets for Cinta Senese breed, to reduce nitrogen pollution in the environment.

“…In accordance, Morales et al (2002) reported that Iberian pigs had lower gut content compared with Landrace pigs, resulting in shorter transit time of digesta. Earlier studies on indigenous and exotic pig breeds support the contention of greater length of the GIT in the indigenous pigs (Freire et al, 1998;Len et al, 2009a).…”

The impact of fibre level and fibre source on digestibility, gastrointestinal tract (GIT) development, total tract mean retention time (MRT) and growth performance was studied in indigenous Mong Cai (MC) and exotic Landrace 3 Yorkshire (LY) pigs. The diets were based on maize, rice bran, soyabean meal, fish meal and soyabean oil, and cassava residue (CR) or brewer's grain (BG) as fibrous ingredient sources in the high-fibre diets (HF) and were fed ad libitum. A low-fibre diet (LF), containing around 200 g NDF/kg dry matter (DM), was formulated without CR and BG as feed ingredients. The HF diets (HF-CR and HF-BG) were formulated to contain around 270 g NDF/kg DM. The experiment was arranged as a 2 3 3 factorial completely randomized design with six replications, and lasted 27 days. Increased dietary fibre level resulted in a reduction (P , 0.05) in average daily gain, digestibility of organic matter (OM), CP and gross energy (GE) at the ileum and in the total tract, and in MRT, and an increase (P , 0.05) in the feed conversion ratio and in the weight of the GIT (except for small intestine and caecum). The coefficients of total tract digestibility of fibre fractions were higher in HF diets than in the LF diet, with highest values for diet HF-CR, which had a high proportion of soluble non-starch polysaccharides. MC pigs had longer MRT of digesta than LY pigs (P , 0.05), resulting in higher digestibility at the ileum and in the total tract. Across diets and breeds, the total tract apparent digestibility of OM, CP and GE was positively related (R 2 5 0.80 to 0.84) to the MRT of solids, whereas the MRT was negatively related to the DM intake (R 2 5 0.60).

“…These observations on Iberian pigs could apply to tropical pig breeds, especially those from Latin America. The high fibre digestibility of native breeds is also explained by a better adaptation to the high fibre content ascribable to high digestive enzyme activity and better adaptation of hindgut microbiota to degrade cell wall constituents of the diet (Freire et al, 1998 and, greater size of the gastrointestinal tract and longer retention time (Ngoc et al, 2013). The ability of indigenous pigs to digest fibrous fractions is more pronounced in high-fibre diets (Len et al, 2009b), which takes place in the hindgut because ileal digestibility of a high-fibre diet is usually similar between breeds in the same trial.…”

Globally, pressure on concentrate feed resources is increasing, especially in the tropics where many countries are net importers of food. Forage plants are a possible alternative, but their use as feed ingredients for pigs raises several issues related to their higher fibre and plant secondary metabolites contents as well as their lower nutritive value. In this paper, the nutritive value of several forage species and the parameters that influence this nutritive value in relationship to the plant family, the physiological stage, the plant part and the preservation method (fresh, hay and silage) are reviewed. The influence of the breed and the physiological status of the animal on animal voluntary intake of fibre-rich ingredients, digestibility as related to gastrointestinal volume and transit time and growth performances are also discussed. The final section highlights the advantages and drawbacks of forage plants in pig diets and stresses the need for proper economic evaluation to conclude on the benefits of the use of forage plants in pig feed.
