“…MAP3K5 also plays an important role in oxidative stress, cellular proliferation, and differentiation, and in immune responses (Harada et al, 2006;Hayakawa et al, 2006;Choi et al, 2011;Prickett et al, 2014). Residual feed intake (RFI) is closely associated with tissue growth, apoptosis, differentiation, gastric emptying rate, and immune responses (De Hear et al, 1993;Kim et al, 2007;Smith et al, 2011;Dunkelberger et al, 2015). Therefore, owing to its multi-functional characteristics, previous studies have suggested that MAP3K5 controls feed efficiency, including RFI (Do et al, 2014).…”

ABSTRACT. Mitogen-activated protein kinase kinase kinase 5 (MAP3K5) is essential for apoptosis, proliferation, differentiation, and immune responses, and is a candidate marker for residual feed intake (RFI) in pig. We cloned the full-length cDNA sequence of porcine MAP3K5 by rapid-amplification of cDNA ends. The 5451-bp gene contains a 5'-untranslated region (UTR) (718 bp), a coding region (3738 bp), and a 3'-UTR (995 bp), and encodes a peptide of 1245 amino acids, which shares 97, 99, 97, 93, 91, and 84% sequence identity with cattle, sheep, human, mouse, chicken, and zebrafish MAP3K5, respectively. The deduced MAP3K5 protein sequence contains two conserved domains: a DUF4071 domain and a protein kinase domain. Phylogenetic analysis showed that porcine MAP3K5 forms a separate branch to vicugna and camel MAP3K5. Tissue expression analysis using real-time quantitative polymerase chain reaction (qRT-PCR) revealed that MAP3K5 was expressed in the heart, liver, spleen, lung, kidney, muscle, fat, pancrea, ileum, and stomach tissues. Copy number variation was detected for porcine MAP3K5 and validated by qRT-PCR. Furthermore, a significant increase in average copy number was detected in the low RFI group when compared to the high RFI group in a Duroc pig population. These results provide useful information regarding the influence of MAP3K5 on RFI in pigs.

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).

“…As fiber fermentation is a function of time [Stevens and Hume, 1998;Clauss et al, 2007; cf. the increase in DM digestibility in domestic pigs with increasing retention time in Kim et al, 2007], a resulting hypothesis of this study is that compared with other suids and peccaries, warthogs should have particularly long ingesta retention times; alternatively-or additionally-warthogs might show adaptations in their dental enamel folding pattern, similar to that of grazing ruminants [Archer and Sanson, 2002], by which they achieve a particularly fine ingesta particle size.…”

Among the artiodactyla, the suids are a group whose digestive physiology has hardly been investigated. The apparent digestibilities (aD) of macronutrients were measured in captive specimens of warthog (Phacochoerus africanus), red river hog (Potamochoerus porcus), and Visayan warty pigs (Sus cebifrons), and compared with those reported for babirusa (Babyrousa babyrussa) from the same facility on a similar diet. The animals were fed mixed diets of pelleted feed, grains, fruits, and vegetables; dietary neutral detergent fiber (NDF) ranged from 17 to 26% dry matter. aD of organic matter and protein ranged from 72 to 89 and 70 to 82%, respectively. Although red river hogs and warty pigs achieved aD of NDF of 41-54%, this value was higher both in warthogs (63-66%) and babirusa (61-63%). aD of acid detergent fiber was comparatively low in red river hogs (4%), warty pigs (22%), and babirusa (13-25%) but high in warthog (59-62%). Comparison with additional literature data (including peccaries) indicates that in spite of differences in digestive anatomy, suids and peccaries are similar, and resemble other herbivores in fundamental characteristics, such as the negative influence of fiber on overall digestibility, or the positive influence of dietary protein on protein digestion. Although the existing data are equivocal as to a superior fiber digestion in peccaries as compared with other wild suids, the results suggest that warthogs are more efficient than other wild suids or peccaries in terms of fiber digestion.
