“…Therefore, the extra energy ingested by birds would be used to activate the mechanisms of heat loss and maintenance of body temperature, with no excess energy for the deposition as adipose tissue. However, our results are in agreement with those of Guerreiro Neto et al (2011) and Cho et al (2012), who did not verify an influence of the use of emulsifiers on the deposition of fat in the abdominal region of the birds.…”

“…For these same characteristics, when the additives were used, Nagargoje et al (2016) did not observe variations in the relative weight of the cuts when comparing the groups of broilers fed diets containing lipase (10 000 IU kg -1 ) to the control group at the end of the period from 1 to 42 days. Guerreiro Neto et al (2011) also did not verify a variation in the carcass yield and cuts of the chickens that received rations supplemented with emulsifiers at 42 days of age.…”

“…Corroborating the viability results, Kamran et al (2008) did not observe variation in the viability of broilers at the end of the breeding cycle in response to the level of metabolisable energy of the ration. Similarly, Guerreiro Neto et al (2011) found that the use of emulsifiers in broiler rations did not influence the viability of rearing broilers, regardless of the sources of metabolisable energy used. In agreement with this, Nagargoje et al (2016) also did not observe an influence of this additive on the viability of broilers.…”

The objective of this study was to evaluate the effect of exogenous emulsifier and lipase in diets on performance, digestibility, and organ biometry of broiler chickens. A completely randomised design with seven treatments and seven replications was adopted. The treatments were as follows: T1 (positive control; PC): 3000, 3100, 3200, and 3250 Kcal of metabolisable energy (ME) kg-1 of diet for phases 1 to 10, 11 to 21, 22 to 31, and 32 to 37 days, respectively; T2: PC with reduction in ME of 30 Kcal kg-1 of diet; T3: PC with reduction in ME of 60 Kcal kg-1 of feed; T4 (negative control; NC): PC with reduction in ME of 90 Kcal kg-1 of feed; T5: NC with inclusion of exogenous lipase (10 000 U kg-1); T6: NC with inclusion of emulsifier (250 g t-1); and T7: NC with inclusion of lipase (10 000 U kg-1) and emulsifier (250 g t-1) in the period from 1 to 37 days of rearing. Performance characteristics (weight gain (WG), feed intake (FI), and feed conversion (FC)), carcass yield, cut yield, the relative weight of abdominal fat and organs (small intestine, liver, and pancreas), and relative intestinal length, in addition to dry matter digestibility (CDADM), ethereal extract (CDAEE), crude metabolisable energy (CMACE), and apparent metabolisable energy (AME) of the diets, were evaluated. In the initial phase, the CDAEE was higher for the PC group than for the emulsifier + lipase group. The AME determined in the final phase for the group supplemented with an emulsifier was higher by approximately 50 Kcal (EM) than the NC group. The WG of the lipase group was similar to that of the PC group. However, the groups with emulsifier and emulsifier + lipase showed a lower WG than the PC group. The additives used did not recover the FC to the same level observed in the PC group. The reduction in ME of 90 Kcal kg-1 generated a lower WG and worse FC. The use of both an emulsifier and lipase together produced results like to the PC group. The biometrics of the organs and the carcass yield and cuts were not influenced by diets. Thus, it can be concluded that the inclusion of lipase and an emulsifier improves the performance of broilers given diets with reduced energy, although it does not improve the lipid utilisation of the diets.

“…Total blood biochemical parameters were not affected by different inclusion rate of SO in present research, as observed by Fascina et al (2009) and Guerreiro et al (2011) who did not find any blood parameters differences between broilers fed vegetable oils. However, results of some studies do not agree with the findings of present experiment.…”

“…Bile salts in aqueous solution spontaneously aggregate to form micelles, these also mix with lipid products during digestion to form mixed micelles and enhance absorption (Stamp and Jenkins, 2008). Several studies have been conducted to investigate the effects of bile salt supplements and emulsifiers on broiler performance (Maisonnier et al, 2003;Al-Zawqari et al, 2010;Guerreiro et al, 2011). The addition of bile salts to poultry diets has resulted in an improvement of fat absorption in chicks (Kussaibati et al, 1982).…”

An experiment was conducted to evaluate the growth performance, carcass characteristics and blood metabolites of broiler chickens fed diets formulated on total or digestible amino acids (TAA or DAA) basis with bovine bile salts powder (BBSP) and different levels of soybean oil (SO). A total of two hundred and forty 1-day old chicks were randomly allocated to eight treatments with three replicates of 10 birds. The experiment was carried out in a completely randomized design with 2×2×2 factorial arrangement, including two levels of BBSP, two levels of SO and two methods of amino acids balance (TAA or DAA) in diets. The results showed that main effects of BBSP, SO and feed formulation procedures (TAA or DAA) had no effects on all growth performance parameters (P > 0.05). Carcass traits, except for thigh weight, were not influenced by all dietary treatments (P > 0.05). The birds fed diets with BBSP had a greater thigh weight than the other group. The results of blood biochemical metabolites indicated that serum triglyceride was affected by amino acid formulation method (P < 0.05). In contrast, the other serum metabolites did not alter by dietary treatments (P > 0.05). The results indicated that liver enzymes activities including alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were not influenced by dietary BBSP and SO (P > 0.05). However, AST activity was affected by amino acids formulation procedure (P < 0.05). In conclusion, the addition of bile salts (BBSP), different inclusion rate of SO and amino acids balance method (DAA or TAA) in broiler diets had no negative effects on all growth performance and carcass traits.

BackgroundThe digestibility of animal fats and oils is limited by a reduction in the production and secretion of lipase and bile salts in young chickens. The addition of a natural emulsifier (lysophospholipids [LPL]) in poultry diet may increase the emulsification of lipids and their digestibility.ObjectivesAn experiment was conducted to evaluate the effects of feed LPLs supplementation with different fat sources on performance, serum lipid composition, small intestine morphology and caeca microflora in broiler chickens.MethodsA completely randomized factorial design (2 × 3 × 2) was used to evaluate the effect of LPL supplementation (0 and 0.25 g/kg) and three different fat sources (soybean oil, tallow and a 50:50 mixture of the two) in corn and soybean meal diets containing two levels of fat (1.5 and 3%), providing 12 isocaloric and isonitrogenous grower diets. Each experimental diet was fed to six replications of 10 birds from 15 to 28 days of age. Average growth performance during this period and small intestine morphology, serum lipid composition and caeca microflora were evaluated on day 28.ResultsThe interaction effects of LPL supplementation, source and/or level of fats were not significant for the performance parameters measured during the 15 to 28 days. The treatment effects were significant for the villus width and crypt depth measured in the jejunum on day 28. The LPL supplementation significantly increased crypt depth. The interaction effect of fat source and level of fat were significant for villus width. The addition of a 3% blend of soybean oil/tallow (50/50) reduced the serum low‐density lipoprotein (LDL) level. The Lactobacillus population was increased by the addition of LPL, or a 1.5% blend of soybean oil and tallow, to the diet.ConclusionsOur study showed that LPL supplementation of diet containing a 1.5% blend of soybean oil and tallow can improve serum lipid indices and caeca Lactobacillus populations in broiler chickens.
