The impacts of dietary levels of oxidized vegetable (sunflower) oil on growth performance, gut morphology, nutrients utilization, serum cholesterol and meat fatty acid profile were evaluated in Ross 308 straight-run (n = 192) day-old broilers. The broilers were arbitrarily distributed among four dietary treatments including; FVO: fresh vegetable oil (1 mEq kg−1), LOO: low oxidized (20 mEq kg−1), MOO: moderately oxidized (40 mEq kg−1), and HOO: highly oxidized vegetable oil (60 mEq kg−1) with 5% inclusion containing six replicates. Results revealed that the broilers consuming MOO and HOO based diets showed reduced (p = 0.05) feed intake, body weight gain and carcass weight accompanied by a poorer feed conversion ratio than those consuming FVO. Villus height, villus height to crypt depth ratio, ileal digestibility of crude protein (p = 0.041), crude fat (p = 0.032) and poly unsaturated fatty acids (p = 0.001) in thigh muscles were decreased, whereas crypt depth (p = 0.001), serum cholesterol levels (p = 0.023) and short chain fatty acids (p = 0.001) were increased (p < 0.001) by increasing dietary oxidation level. In conclusion, MOO and HOO exerted deleterious effects on growth, carcass weight, gut development and nutrients utilization. Low oxidized vegetable oil (20 mEq kg−1), however, with minimum negative effects can be used as a cost effective energy source in poultry diets.

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.

Thirty-two 6-month-old, healthy Nanjiang Yellow goats (34.6 ± 4.16 kg) were randomly divided into four treatments to evaluate the supplementary effects of branches and leaves trimmed from tea tree (BLTT) on growth performance, rumen fermentation characteristics, and meat composition in fattening goats. The control goats were fed a basal diet. Treatments 1, 2 and 3 were fed 2%, 4% and 6% of BLTT respectively. After a 60 d feeding trial, blood samples were collected for the analysis of the antioxidant profile and goats were slaughtered to obtain the rumen fluid and carcass samples for determination of rumen fermentation characteristics and meat composition perameters. Increased final body weight was observed in goats fed 4% BLTT compared with control. The activity of superoxide dismutase was increased in the 4% BLTT-treated group, while glutathione peroxidase and malondialdehyde followed the quadratic curve. Quadratic curves were also observed for villus height, crypt depth and the ratio of villus height to crypt depth in the jejunum. The quadratic effect was obtained for total essential amino acids, and individual amino acids threonine and leucine. The saturated fatty acid C16:0 was decreased with 4% of BLTT supplementation, and a quadratic effect was observed for polyunsaturated fatty acid C18:3 (n−3). To sum up, our findings revealed that BLTT supplementation has a positive effect on body antioxidative status, gastrointestinal development, rumen fermentation characteristics and overall growth performance and meat quality in goats.

The present study was conducted to evaluate the effect of algal meal incorporated diets on the growth performance and fatty acid profile of tilapia Oreochromis mossambicus (Peters, 1852). Control diet (Diet 1) for the study was formulated with rice bran, groundnut oil cake (GNOC) and soybean meal. Six iso-energetic and iso-nitrogenous test diets (Diets 2 to 7) were prepared by incorporating (@40%) one of the four microalgae viz., Anabaena cylindrical (AN; Nostoc salbasa (NS); Spirulina platensis (SP) and Westiellopsis prolifica (WS) or with an algal meal mixture containing the above four algae plus the macroalgal species viz., Gracilaria edulis (GE) and Enteromorpha intestinalis (EI) mixed in equal proportions along with sunflower oil and cod liver oil (by totally replacing rice bran, GNOC and soyabean meal of the control diet) (AMM+O diet, Diet 6) and AMM without addition of oils served as AMM diet (Diet 7). The algal meal supplemented diets were tested against a control diet to find out their suitability for culture of tilapia fingerlings. The fish (av. wt. 2.8 ± 0.4 g) were fed up to satiation for 56 days at 28±20C. Significant (p<0.05) enhancement in growth was observed with AN (565.2%) diet followed by SP (500%) and WS (400%) compared to control (402.3%). The AN diet showed best performance in terms of feed conversion ratio (FCR), protein efficiency ratio (PER) and specific growth rate (SGR) while AMM diet showed least efficiency. Fish fed with SP diet showed better apparent net protein utilisation (ANPU%) as compared to other diets. Saturated fatty acid (SFA) in the liver and muscle decreased while monounsaturated (MUFA) and polyunsaturated (PUFA) fatty acids increased over their respective initial values in all the dietary groups except in groups fed with AMM+O and AMM. The n-6 level of liver and muscle increased with SP diets. Substantial increase in docosahexaenoic acid (DHA, 22:6n3) and eicosapentaenoic acid (EPA, 20:5n3) in fish fed with WS emphasised the benefits of its use as dietary ingredients for tilapia. The results clearly indicated that algae like AN and SP incorporated in tilapia diet significantly enhance growth and carcass protein, whereas WS helps to improve the levels of the essential n-3 fatty acids (EPA and DHA).

AbstractThe effects of caponization on growth performance, carcass characteristics, meat quality and fatty acid profile of breast and drumstick of Mos and Sasso genotypes, reared in free-range production system were examined. A total of 47 birds of Mos breed (19 Castrated and 25 Entire) and 37 of Sasso X-44 (18 Castrated and 19 Entire) slaughtered at 32 weeks were used in this trial. The growth of broilers and the differences between genotypes and caponization effects were modelled by Weibull-growth equation. Capon’s growth was higher than that obtained by roosters and Sasso weight was greater than Mos results (P<0.05). For both genotypes the chemical composition of breast and drumstick cuts showed significantly higher values of intramuscular fat (P<0.0001) and lesser values of moisture (P<0.0001) in capons in comparison with intact ones. In Mos breed, capons exhibited significantly (P<0.0001) higher values of breast and drumstick luminosity and yellowness, as well as lower values of redness. Regarding Warner-Braztler test (WB), there were no significant differences (P>0.05) by caponization effect, but hardness measured using textural profile analysis was lesser in meat from capons. Finally castration of animals led to important modifications in the intramuscular fat because meat from capons showed significantly lower values for total saturated fatty acids (SFA) and higher polyunsaturated fatty acids (PUFA ). Nutritional indices were also more favorable in capon’s meat, so overall fatty acid profile of capons was desirable from the viewpoint of human nutrition.

Abstract Background There has been an increased interest in nutritional strategies to manipulate the fatty acid profile of pigs. Dietary regimens involving the use of oils that are high in monosaturated fatty acid (MUFA), primarily oleic acid (OA), such as canola oil (CO), as well as in omega (n)-3 polyunsaturated fatty acid (PUFA), which are found in fish oil (FO), have been investigated aiming healthier fatty acid profile cuts, with a higher ratio of n-3 to n-6 fatty acids. Therefore, the effects of including 3% soybean oil (SO), CO, or FO in growing-finishing pig diets vs. feeding a standard commercial diet with 1.5% SO (control) on growth performance, carcass traits, meat quality, consumer acceptability, and intramuscular fatty acid composition of the longissimus lumborum (LL) muscle were evaluated. Results Dietary treatments had no effect on overall growth performance and pig carcasses. Although loins from pigs fed diets containing either 3% SO or CO showed a reduction (P = 0.05) in Warner-Bratzler shear force, only the addition of 3% SO to pig diets resulted in loin chops that were rated higher (P < 0.001) for consumer overall liking. Adding either 3% SO or CO increased (P < 0.01) the percentages of OA and total MUFA in the LL intramuscular fat compared to control- or FO-fed pigs. However, intramuscular fat from 3% SO- or CO-fed pigs had the lowest (P < 0.01) proportion of total n-3 PUFA than control- or FO-fed pigs. Including 3% fat, regardless of source, reduced (P < 0.01) total PUFA, total n-6 PUFA, and PUFA:saturated fatty acid (SFA) ratio than control-fed pigs. Dietary FO inclusion decreased (P < 0.01) n-6:n-3 PUFA ratio, but also increased total SFA (P < 0.01) and atherogenic index (P = 0.02) in the LL intramuscular fat. Conclusions Although adding 3% CO or FO to pig diets provided slight nutritional benefits to consumers in terms of MUFA and long chain n-3 PUFA contents, respectively, formulating growing-finishing diets with 1.5% SO was adequate enough in terms of LL intramuscular fatty acids composition for high quality meat destined to human consumption.

The aim of the present study was to determine the effect of supplementing the diets of broiler chickens with Camelina sativa oil or cake as a source of polyunsaturated fatty acids (PUFAs) on their growth performance, fatty acid profile, and sensory quality of meat. The 456 Ross 308 broilers aged 21–42 days were divided into 3 groups with 4 replicates of 38 birds in each. Chickens in the control group I (CTR) were fed a standard grower–finisher feed mixture containing 60 g/kg rapeseed oil. The experimental components, C. sativa oil—CSO (group II) or cake—CSC (group III), were included in a diet based on wheat and soybean at 40 and 100 g/kg, respectively. The use of Camelina oil and cake as feed components did not have a significant effect on the growth performance of the chickens. Analysis of the fatty acid profile in the lipids of the breast muscles showed that Camelina oil and cake reduced the content of monounsaturated fatty acids (p < 0.05) but increased the content of n-3 polyunsaturated fatty acids, especially α-linolenic acid (C18:3) (p < 0.01). Furthermore, both components reduced the ratio of n-6/n-3 PUFAs in the breast muscles (p < 0.01). Sensory analysis revealed that Camelina oil had a beneficial effect on meat juiciness, whereas Camelina cake slightly worsened the flavor and tastiness of the meat. In conclusion, supplementing the diet of broiler chickens with Camelina oil or cake can be an efficient method for modifying the fatty acid profile of the meat lipids in a beneficial way, without any negative impact on the growth performance of the chickens. According to the dietetic recommendations for humans, broiler chicken meat with a higher level of PUFA n-3 can be a good alternative source of these fatty acids in the human diet. Furthermore, Camelina oil improved the juiciness of breast meat.

A 90-day feeding trial was conducted to evaluate the effects of diets supplemented with three concentrations (control or 0%, 0.5% and 1.0%) of fermented Saccharina japonica and Dendropanax morbifera (FSJ-DM) on the meat composition, growth performance, oxidative stability and fatty acid profile of Korean native black goat (KNBG) meat. The feed conversion ratio and body weight gain (1st to 2nd month) were improved significantly (p < 0.05) in response to feed supplemented with 1.0% FSJ-DM. Moisture content was increased, whereas ether extract and cholesterol contents were decreased in meat obtained from goats supplemented with 1.0% FSJ-DM dietary feeds (p < 0.05). In the same diet group, the total saturated fatty acids (ΣSFA) were lower, whereas the sum of polyunsaturated fatty acids (ΣPUFA) was higher, along with higher PUFA/SFA ratio and lower n-6/n-3 ratio (p < 0.05). On an average, the dietary supplementation of 1.0% FSJ-DM reduced the thiobarbituric acid reactive substance (TBARS) and pH values of goat meat. Overall, the results of this study suggest that diet supplemented with 1.0% FSJ-DM improves the meat composition, growth performance and fatty acid profile and reduces lipid oxidation of goat meat.
