“…Abdominal incisions were then made to separate the ileum and jejunum from the gastrointestinal tract. The jejunum was defined as the part before the vitelline diverticulum (formerly Meckel's diverticulum) whereas the ileum was defined as the part of the ileum extending from the vitelline diverticulum towards the ileo-caecal junction [3]. A cut was then made of the ileum (3 cm) from the vitelline diverticulum and then flushed with phosphate-buffered saline (PBS) at pH 7.4.…”

Objective: To investigate the physiological effects of exogenous emulsifiers in broiler chickens that were fed tallow-incorporated reduced-energy diets over 35 days.Methods: A total of 256 Ross 308 one-day-old broilers (42.28 ± 0.16 g) were randomly allocated in a 2 × 2 factorial arrangement to 32 pens with eight chicks per cage. Birds were fed one of four dietary treatments as follows: (1) positive control (PCN; energy sufficient diet); (2) negative control (NCN; energy-deficient diet, -100 ME kcal/kg); (3) PCL (PCN plus 0.05% emulsifier) and ( 4) NCL (NCN plus 0.05% emulsifier). Growth performance was evaluated weekly whereas assessments for the carcass traits, digestibility, some blood metabolites, ileal morphology, and meat quality were measured on d 21 and d 35.Results: Birds fed the NCL diet had higher (P < 0.05) body weights, daily gains, daily feed intake, and improved feed efficiency over the entire 35-day period. Improvements (P < 0.05) for the ileal digestibility of crude fat, energy, and dry matter commensurate with longer (P < 0.05) villus heights were also observed with emulsifiers in the NCL and PCL diets. For the carcass measurements, only the liver weights were increased (P< 0.05) with emulsifiers in the supplemented groups. For blood metabolites, higher (P < 0.05) lipase levels were noticed with emulsifiers in the NCL and PCL diets. In addition, marginal reductions (P = 0.076; P= 0.095, respectively) were also noted with emulsifiers for the total cholesterol and triglyceride contents on d 35. Regarding meat quality, breast muscle yellowness was increased (P < 0.05) with emulsifier use in supplemented groups.

A 56-day feeding trial was conducted in a flow-through seawater system to investigate the effects of lysophosphatidylcholine (LPC) on growth performance and lipid metabolism of turbot. Four experimental diets were prepared, differing only in the LPC supplementation, namely, 0 (LPC-0, control), 0.1 (LPC-0.1), 0.25 (LPC-0.25), and 0.5% (LPC-0.5) of dry matter. Each diet was randomly fed to triplicate tanks. LPC-0.1 and LPC-0.25 led to significantly higher weight gain than the control diet, and the highest weight gain was observed in LPC-0.1. Compared to the control group, the LPC-supplemented groups had higher survival and lower hepatosomatic index and viscerosomatic index. LPC-0.25 led to significantly lower contents of crude lipid and ash in whole fish. Dietary LPC supplementation led to a basic decrease in the lipid metabolism-related biochemical parameters in serum but had only very minor influence on the fatty acid composition in the liver and subcutaneous tissue around the fin (STF). High LPC levels upregulated the mRNA expression of BSAL and ApoEα in both the liver and STF. In conclusion, dietary LPC supplementation (0.1-0.25%) enhanced the growth, lowered the lipid accumulation in juvenile turbot, and significantly regulated the lipid metabolism. However, it seldom influenced the fatty acid composition.

This study was conducted to evaluate the efficacy of a combination 3, 4, 5trihydroxybenzoic acid (THB) and oregano extracts (i.e., Carvacrol and Thymol) at intake/dietary different levels on growth performance, intestinal health indicators, immune responses and fecal oocyst shedding in broiler chickens under Eimeria challenged condition.A total of 336 one-day-old broilers were randomly assigned to one of six dietary treatments with seven replications per treatment. Dietary treatments were: i) Non-challenged bird without any dietary treatment (NCNT), ii) Challenged bird without any dietary treatment (CNT), iii) Challenged birds fed a THB diet (0.1 g/kg, THB), iv) Challenged birds fed a combination of THB and oregano extracts diet (0.1 g/kg, COM 100), and a gradual increase of combination of THB and oregano extracts likely v) 0.15 g/kg (COM 150), and 0.2 g/kg (COM 200). On day 14, all groups except for NCNT have orally challenged with a 10-fold dose of Livacox ® T anticoccidial vaccine to trigger coccidiosis. The results indicated that Eimeria-challenged broilers fed COM 100 and COM 200 diets increased (P < 0.05) body weight (BW) than CNT diet on day 35. Furthermore, birds fed COM 100 and COM 200 diets increased (P < 0.05) average daily gain compared to those fed CNT diets for the entire experimental period. There is no significant (P > 0.05) in average daily feed intake, feed efficiency between NCNT and birds fed with combined THB and oregano extracts for the entire experimental period. A combination of THB and oregano extract regardless of concentration levels or THB alone reduced (P < 0.05) lesion score in ileum compared to the CNT diet for 7 days post-infection (dpi). Birds fed COM 100 diet had lower (P < 0.05) intestinal lesion scores in jejunum and caeca on 7 dpi compared to those were in the CNT diet. No (P > 0.05) difference was observed in the oocysts per gram of feces (OPG) count, intestinal morphology, carcass traits and blood cytokine concentration among the infected treatments. Collectively, we conclude that birds fed A C C E T E Dwith a combination of THB and oregano extracts regardless of the ratios that were used demonstrated better recovery of health after the coccidial challenge than using only THB alone.
