Fermented Feed

Microbial fermented feed is an important part of feed industry, while little research has focused on the solid-state fermentation of complete feed. Herein, the purpose of the present study was to investigate the effects of fermented complete feed (FCF) on the growth performance, biochemical profile, carcass traits, meat proximate composition, meat amino acid and fatty acid profile, and gut microbiome composition of finishing pigs, thereby providing references for the application of FCF in animal production. Twenty Duroc × Landrace × Yorkshire pigs with an average body weight (BW) of 48.74 ± 1.49 kg were divided randomly into control group (pigs received a basal diet, CN, n = 10) and FCF group (pigs fed with FCF, n = 10). The experiment lasted for 60 days. FCF improved the growth performance, which was indicated by a significantly increased final BW, average daily gain and average daily feed intake, and a significantly decreased feed-to-gain ratio. FCF improved biochemical profile, which was indicated by a higher alkaline phosphatase, glucose, immunoglobulin G, immunoglobulin M, superoxide dismutase, and total antioxidant capacity content. Pigs that received FCF had better carcass traits and meat quality than did pigs that received basal diet, which was indicated by a higher carcass length, crude protein content, lysine content, Glu content, C18:ln9c, C18:2n6c, C20:4n6, and unsaturated fatty acid content and a lower average back-fat thickness, C18:0, and saturated fatty acids. FCF significantly reduced the relative abundances of presumably pathogenic bacteria of phylum Proteobacteria and genus Escherichia–Shigella and enhanced the relative abundances of likely beneficial bacteria of phylum Firmicutes and genus Clostridium. In summary, FCF had a certain effect on the improvement of growth performance, serum biochemical profile, carcass traits, meat proximate composition, amino acid and fatty acid profile, and gut microbiome composition of finishing pigs.

Leaf Meal

A total of 144 cross-bred (Duroc × Landrace × Yorkshire) finishing pigs with a similar initial weight (65.4 ± 1.03 kg) were used to investigate the effect of moringa leaf meal on growth performance, meat quality, fatty acid composition, and amino acid profile. The moringa leaf meal-inclusion rates were 0% (M0 or control), 3% (M3), 6% (M6) and 9% (M9). The results showed that supplementing moringa leaf meal significantly increased the daily weight gain of finishing pigs, but had a minor impact on pork quality indicators and the amino acid profile in the Longissimus dorsi. The fatty acid profile in the Longissimus dorsi was significantly modified when pigs were fed moringa leaf meal diets. The relative percentage of total unsaturated fatty acid and monounsaturated fatty acid was higher in the meat of pigs fed a 6% moringa leaf meal diet than in the meat of those receiving the control diet. In contrast, the percentage of total saturated fatty acids was lower in the meat of pigs fed the moringa leaf meal diets. Moreover, the omega-6/omega-3 ratio decreased with moringa leaf meal supplementation. Addition of the moringa supplement into the diet of pigs improved growth performance and modified pork fatty acid profile positively. The results suggest that moringa leaf meal could be used as a diet supplement for producing healthier pork.

He, M. L., Xu, L., Yang, W. Z., Gibb, D. and McAllister, T. A. 2014. Effect of low-oil corn dried distillers’ grains with solubles on growth performance, carcass traits and beef fatty acid profile of feedlot cattle. Can. J. Anim. Sci. 94: 343–347. The objective of this study was to investigate the effects of dietary inclusion of low-oil corn dried distillers’ grains with solubles (LO-DDGS) on growth, carcass traits and beef fatty acids profiles of finishing feedlot cattle. One hundred and eighty British crossbred steers (450±28.5 kg; six pens/treatment) were offered barley grain-barley silage as the control diet with LO-DDGS replacing barley grain at 200 and 300 g kg−1 dry matter basis in treatment diets. Compared with control, LO-DDGS at 200 g kg−1 did not affect growth performance or carcass traits, whereas at 300 g kg−1 it decreased (P<0.05) gain:feed, but increased (P<0.05) levels of desirable fatty acids in beef. LO-DDGS can replace 200 g kg−1 barley grain in finishing feedlot diets without undesirable impacts on growth performance or carcass traits.

Finishing Pig

An experiment was carried out in the Animal Science Department of Lavras University to determine the effects of different oils on the performance, carcass traits and fatty acid profile of meat from finishing pigs. In total, 80 Large White × Landrace animals, including 40 gilts and 40 barrows, with an average initial weight of 68.50 ± 1.45 kg, were used. Isoenergetic, isoprotein and isolysinic diets based on corn and soybean meal without the addition of oil or with 2% soybean oil, canola oil, linseed oil or PUFA commercial oil were tested. No significant (P > 0.05) effects were observed in the pigs’ performance. However, significant (P < 0.05) improvements were observed regarding the percentage of meat on the carcass and the loin area with the addition of linseed oil (2%) in the diets. The carcasses of the pigs fed diets containing linseed oil also had higher content of protein in the femoral biceps muscle compared with those from pigs fed soybean oil diets. The fatty acid composition of the intramuscular fat of the longissimus dorsi muscle reflected the composition of the oils added to the diets. In conclusion, linseed oil at 2.0% in the finishing pig diet improved lean tissue accretion (lean meat and loin area in the carcass). In addition, the fatty acid deposition in the muscles followed the dietary fatty acid profile.
