“…Absorption of long-chain saturated FA was also reported to be low in the small intestine because of their high melting point relative to body temperature (Cheng et al 1949) and because of their ability to form low-solubility calcium salts (Ramírez et al 2001). Post-weaned pigs were fed diets supplemented with either medium-chain FA or long-chain FA and either without or with an added emulsifier (Price et al 2013).…”

Effects of feeding lipid supplements high in free fatty acids (FAs) of palmitate (C16:0) or stearate (C18:0) plus C18:1 cis 9&10 on milk yield and composition, apparent whole-tract apparent digestibility of FA, and the FA composition of milk lipids were studied. Four lactating Holstein cows with ruminal cannulae were used in a 4 × 4 Latin square assignment of four dietary treatments. Lipid supplements were enriched in free fatty concentrations of either palmitic acid (P) or stearic acid (S). The total mixed-ration contained 20 g/kg of lipid supplement that consisted of varying proportions of P to S. Treatments were: 100:0 P:S (P), 0:100 P:S (S), and two mixtures including 66:34 P:S (PS) and 34:66 P:S (SP). Milk yield and dry matter intake were not affected by lipid supplement, but the concentration and yield of fat in milk increased with increasing C16:0 in the lipid supplement. Increasing the C16:0 concentration in the lipid supplement increased its concentration in milk lipids while increasing C18:0 in the lipid supplement increased C18:0 concentration in milk fat. Whole-tract apparent digestibility of neutral detergent fiber (NDF) did not differ with lipid supplement, but organic matter digestibility tended to decrease with increasing C18:0 in the lipid supplement. Whole-tract digestibility of total FAs decreased with the increasing proportion of C18:0 to C16:0 in the lipid supplement. Apparent digestibility of C16:0 and C18:0 was not different within dietary treatment. The FA composition of the lipid supplement impacted both whole-tract digestibility of FAs and FA composition of milk lipids. ARTICLE HISTORY

“…PKM fat contained characteristically higher proportion of C12~C14 chain fatty acids (Atasie and Akinhanmi, 2009). It is also known that those fatty acids are relatively readily absorbable than other fatty acids (Ramirez et al, 2001;Ong and Goh, 2002). It is not clear why crude ash utilization was decreased by dietary mannanase supplementation.…”

This study was conducted to evaluate the effect of dietary β-mannanase supplementation and palm kernel meal (PKM) inclusion (5%) on laying performance, egg quality and nutrient utilizability of laying hens with 73 weeks of age. A total of 240 Lohmann brown laying hens with average 77.5% egg production were randomly allocated with 60 hens per treatment, 4 replicates per treatment and 15 hens per replicate. Experimental design was a completely randomized design with 2 × 2 factorial arrangement, with the factors being (1) two levels of PKM (0 vs. 5%) and (2) with or without dietary β-mannanase (480 IU/kg of diet CTCzyme ® ) supplementation. All hens were housed in cages (35 cmW × 35 cmD × 40 cmH) with 2 hens per cage for six weeks feeding trial. Laying performance was recorded daily during feeding trial. Egg quality, nutrients utilizability and blood assays were done at the end of feeding trial. Egg production was improved (P<0.05) by both dietary PKM inclusion and β-mannanase combined supplementation. Either β-mannanase or PKM did not affect feed intakes and feed conversion ratio of all diets. Egg weight of hens fed diet containing 5% of PKM had heavier (P<0.05) eggs compared with hens fed without PKM. Albumen height was improved (P<0.05) by dietary mannanase supplementation. Crude fat utilization of 5% PKM diet was higher than that of no PKM diet regardless of β-mannanase supplementation. Both DM and total carbohydrate utilization were decreased (P<0.05) in hens fed 5% PKM diet. Serum IgG and yolk IgY contents of PKM groups were lower (P<0.05) than those of no PKM groups. This result showed that 5% PKM diet, independent of dietary β-mannanase supplementation, was able to improve egg production. In addition, dietary β-mannanase supplementation could be used for improving the albumen height of eggs.

“…The surface area of dietary lipids is then increased, which benefits their emulsion (formation of lipid droplets) in the stomach. During the initial gastric process, partially emulsified triglycerides are attached by lingual and gastric lipases that are similar enzymes in structure and physicochemical characteristics (Ramirez et al, 2001). The activity of these lipases towards short-chain, medium-chain and long-chain fatty acids is not the same.…”
