“…This response agrees with previous data obtained in pigs (Jørgensen & Fern andez 2000;Kil et al 2010;Leek et al 2004) and poultry (San Juan & Villamide 2000). Greater apparent digestibility of extracted lipid than of intact lipid has also been reported for soybean oil (Agunbiade et al 1992), palm kernel oil (Agunbiade et al 1999) and sunflower oil (San Juan & Villamide 2000).…”

The effects of dietary lipid source (corn germ vs. corn oil) on digestible energy (DE) and apparent total tract digestibility (ATTD) of various chemical constituents were evaluated in diets fed to growing pigs. Thirty barrows were allotted to one of five treatments with six replicates per treatment. The five diets were comprised of a corn-based basal diet with 15.64 MJ/kg of GE, LCO and LCG diets (containing 1% extracted corn oil or 2% corn germ, respectively) were formulated to maintain 16.00 MJ/kg of GE, as well as HCO and HCG diets (containing 2% extracted corn oil or 12% corn germ, respectively) were formulated to maintain 16.94 MJ/kg of GE. The differences in ATTD of NDF and ADF were neither observed between the LCO and LCG diet nor between the HCO and HCG diet. LCO diet had greater DE and ATTD of GE and EE (p < .01) compared with LCG diet, and HCO diet exceeded HCG diet in these traits (p < .01). Results from this research indicate that dietary corn oil inclusion increased the DE and ATTD of GE and EE of the diet in comparison with diets using corn germ. These results imply that the additional lipid from extracted corn oil results in a more digestible diet compared to diets using intact corn germ and the fibrous components in diets containing corn germ can decrease the ATTD of EE, GE and the DE of diets.

“…Similarly, inclusion of 18.9 to 19.2% crude fat from fish oil, rapeseed oil or coconut oil in diets did not affect total digestibility of DM, energy and protein in young pigs . However, in other experiments, such as that of Jorgensen and Fernandez (2000), fat inclusion in the diet determined a clear improvement of crude protein and amino acid digestibility. In this connection, level as well as nature of fats included in the diet of pigs could be implied in different animal response through digestibility indices.…”

“…It is well known that the digestibility of unsaturated fatty acid is practically complete even at the ileum level in pigs (Jorgensen and Fernandez, 2000;Duran-Montge et al, 2007). On the other hand, it could be expected that an improvement in crude fat digestibility should occur in pigs as a result of increasing the percentage of dietary crude fat (Just, 1989).…”

The effect of breed and dietary avocado level on the total apparent digestibility (RAD) and balance of nitrogen (N) energy, in young pigs, was studied. Four Pelón Mexicano (PM) and four Yorkshire × Landrace (Y×L) barrow male pigs (39.2 kg average inital liveweight) distributed in two groups according to a change over design in a 2×2 factorial arrangement (breed and diet) were used. The pigs received on a pair feeding basis (0.10 kg DM/kg W 0.75 per day), the experimental diets. The diets were formulated to contain 30 or 150 g crude fat by partial replacement of the maize/soyabean meal diet by avocado (Persea americana Mill.) fresh pulp. The RAD of crude fat was 73.8 and 71.5% and that of N was 83.4 and 82.8 % in PM and Y×L pigs, respectively. There was no significant effect (P>0.10) of crude fat level on RAD of N and energy. N and energy balance significantly (P<0.05) favoured Y×L as compared with PM pigs. In conclusion, the poor N retention of PM pigs could be related to body composition of this local, non improved genotype. The use of avocado for feeding pigs, PM included, should determine a high digestibility of the crude fat fraction and at the same time a considerable deterioration of N retention, probably due to an unbalanced composition of amino acids. The level of avocado pulp inclusion in the diet of the pig should be involved in these circumstances.

“…This seems to suggest that unsaturated lipid may be easier to digest than saturated lipids (Scheeder et al, 2003). Conversely, previous papers described that vegetable oil (expressed as unsaturated fatty acids) or animal fat (representing extremes of saturated fatty acids) did not affect the fat digestibility in pigs (Jørgensen and Fernández, 2000;Kil et al, 2011). The results on the growth performance of growing pigs fed a diet without fat or a diet containing 3% fat with different U:S ratios are shown in Table 3.…”

SUMMARYFat and oils are the most concentrated energy source for pigs. Various fat sources differ considerably in their physical-chemical characteristics and fatty acid profile. Therefore, the current study aimed to evaluate the effect of diets containing 3% fat with different ratios of unsaturated to saturated fatty acids (U:S) on the nutrient digestibility, energy utilization and growth performance of growing pigs. In experiment 1, a total of 6 crossbred, castrated male pigs (Duroc × Large White × Landrace) were used to determine the nutrient digestibility and energy utilization according to a repeated 3 × 3 Latin square design. Each of the two pigs was fed with one of the three diets containing 3% fat with a U:S ratio of 3, 4 or 5, respectively. No differences (P>0.05) in the nutrient digestibility were observed among groups, but the highest digestible and metabolizable energy (P<0.05) appeared in pigs receiving the dietary U:S ratio of 4. In experiment 2, a total of 30 pigs (with an equal number of entire males and females) were allotted into 3 groups in a randomized complete block design. Pigs were fed a diet without fat (T1), or the diets containing 3% fat with U:S ratio of 4 (T2) or 5 (T3), respectively.Although there were no significant difference in any growth criteria, average daily gain and feed conversion ratio was slightly improved (P>0.05) in the T2 group. In conclusion, the present results suggest that diets containing 3% fat with a U:S ratio of 4 is optimal for improving energy utilization in growing pigs and results in a slight enhancement of performance.
