“…The haematological results in our study are in agreement with Al-Daraji et al (2010) who showed that flaxseed (source of omega-3) increased erythrocyte number, PCV, Hb and leukocyte number. Our results are also in agreement with some of the previous reports (Bond et al;Kadhim, 2010;Radwan et al;Jameel, 2013;Al-Zuhairy and Jameel, 2014). The increase of antibody titer against ND virus could be due to omega-3 components are important for the development of the immune cell structure and eicosanoid formation.…”

The goal of the study was to investigate the influence of in ovo injection of omega-3 fatty acids on performance traits, blood parameters and immune response in broilers. At day 14 of incubation, 124 fertilized eggs (31 eggs for each group) were injected with different levels of omega-3 fatty acid (0.05, 0.1 and 0.15 ml) and one was kept as a control. After hatching, 108 chicks were distributed into four groups (27 chicks for each group) and each group was subdivided into three replicate (9 chicks for each replicate). Results revealed that in ovo injection with omega-3 fatty acids on 14 day of incubation resulted in significant increase in the hatchability and final body weight. Haematology (WBC, RBC, PCV, Hb) improved significantly in treated chicks as compared with control chicks. Furthermore, immune response of chicks treated with mega-3 against ND disease increased significantly compared with non-injected chicks. In conclusion, in ovo feeding of omega-3 fatty acids, at the levels of 0.05,0.1 and 0.15 ml resulted in a significant improvement in production traits, haematological parameters and immune response in broiler.

“…The inconsistence might be due to the differences among the trial designs of those researches. The relatively higher breast muscle weight in CO, CL1, and CL2 treatments may be related with that the diets containing corn oil were more beneficial to the breast muscle development of broiler chickens, or that the antinutritional factors in linseed oil had some negative effects on the breast muscle development of broilers (Bond et al 1997). It was reported by Brue and Latshaw (1985) that daily heat production was lesser when corn oil was fed to broiler chickens.…”

ABSTRACT:The effect of dietary 18:2n-6/18:3n-3 ratio (by the replacement of corn oil with linseed oil) on n-3 polyunsaturated fatty acids (PUFA) enrichment in breast muscle of broiler chickens and the expression of lipogenic genes were investigated. Broiler chickens were fed ad libitum with diets containing 5% corn oil (CO), 3.75% corn oil + 1.25% linseed oil (CL1), 2.5% corn oil + 2.5% linseed oil (CL2), and 5% linseed oil (LO) based on the basic diets, respectively. Dietary 18:2n-6/18:3n-3 ratio did not affect 42-day body weight and 0-42-day feed conversion efficiency (feed/gain, P > 0.05) of broiler chickens, however, 5% linseed oil significantly increased 0-21-day feed conversion efficiency (feed/gain, P < 0.05) and decreased breast muscle weight (by 16%, P < 0.05) of broiler chickens. With the decrease of dietary 18:2n-6/18:3n-3 ratio, the enrichment of total n-3 PUFA, 18:3n-3, 20:5n-3, and 22:5n-3 increased linearly (P < 0.01), while the enrichment of total n-6 PUFA and 18:2n-6 decreased linearly (P < 0.01) in breast muscle of broiler chickens. Dietary corn oil increased the enrichment proportion of 20:4n-6 in a dosage-independent manner. Replacing 1.5% corn oil with linseed oil increased the enrichment proportion of 22:6n-3 (P < 0.05), but continuing to increase dietary linseed oil could not further elevate its deposition. Real-time quantitative RT-PCR was used to determine the expression of the mRNA levels of related genes. Dietary PUFA had insignificant effect on the expressions of LPIN2, WD, and tetratricopeptide repeats 1 (WDTC1) and △-6 fatty acid desaturase (FADS2) in both breast muscle and abdominal fat. The effect of dietary PUFA on the expression of LPIN1 gene showed clear tissue dependence. Equivalent adding of corn oil and linseed oil could up-regulate the mRNA level of LPIN1 in abdominal fat (P < 0.01). This study demonstrated that decreasing dietary 18:2n-6/18:3n-3 ratio promoted the deposition of desirable n-3 long chain PUFA in the edible tissue and influenced the expression of LPIN1 in a tissue-dependent manner.

“…In addition to these supplements, methionine and cystine (M + C) were also added to fulfil the requirements (BIS 1992). or whole form reduced the body weight and FCR. Bond et al (1997) concluded that flaxseed was not a practical oil source, as more than 10% of flaxseed in the diet caused a significant performance reduction. Shen et al (2005) also observed lower weight gain and poor feed conversion efficiency in the birds fed with flaxseed supplemented diet as compared to canola or extruded full-fat soybean-based diets.…”

A 42-day study was conducted to evaluate the effect of ground full-fat flaxseed supplementation on growth performance, carcass characteristics, α-linolenic acid (ALA), linoleic acid (LA) and organoleptic characteristics of broiler meat. A total of 200 one-day-old broiler chicks were randomly allocated to five experimental groups and were fed isoenergetic and isonitrogenous diets containing flaxseed at 0%, 2.5%, 5.0%, 7.5% and 10%. Flaxseed supplementation did not affect the weekly body weight of broiler chicks during the first three weeks, but thereafter it reduced significantly with increasing levels of flaxseed in the diets. Birds fed on 10% flaxseed showed a reduction of 10.08% in body weight as compared to the control group. Diets containing 5.0-7.5% flaxseed resulted in significantly lower weight gain, higher feed conversion ratio, energy efficiency ratio and lower protein efficiency ratio as compared to control and 2.5% flaxseed diets. The carcass characteristics data indicated a little variation in the evisceration rate and giblet among treatment groups, but the breast yield was significantly higher in control than flaxseed groups. The protein, fat and ash content of broiler meat were not affected with the level of flaxseed in the diets. However, the inclusion of flaxseed in the diets significantly increased the ALA in the breast and thigh tissues with no difference in the organoleptic quality of meat.
