“…It is likely that the studied FAS had equilibrated; the plasma FAS of captive herring gulls Larus argentatus have been found to change with dietary switches in a few days (Käkelä et al 2005, and the half-life for fatty acids of avian adipose tissue is also relatively fast, about 20 d in chickens (Foglia et al 1994). The calibration factors calculated for the transfer of the signal from the diet to tissue differed considerably for individual fatty acids and in adipose tissue and plasma, and also somewhat in the 2 dietary groups (pelagic versus demersal).…”

Dietary studies of seabirds provide information on food webs and oceanographic variability. Studying fatty acid signatures (FAS), which reflect changes in the composition of the diet, has several advantages over traditional methods. In the context of the Mediterranean marine ecosystem, we studied tissue FAS in captive-fed and wild seabirds. Yellow-legged gulls Larus michahellis were experimentally fed either pelagic (sardine Sardina pilchardus) or demersal (spotted flounder Citharus linguatula) fish for 8 wk, and FAS in the birds' plasma and adipose tissue were studied. The FAS developed patterns characteristic of the sardine or flounder diet, showing the reliability of both types of samples. In addition, plasma samples of 20 endangered wild Balearic shearwaters Puffinus mauretanicus and their most likely prey items from the Mediterranean Sea were collected and analyzed for FAS. Based on FAS of Mediterranean fish, and the results from the feeding experiment, the diet of the endangered wild shearwaters was estimated. In terms of the composition of polyunsaturated fatty acids, the plasma FAS of the shearwaters resembled those of the captive gulls kept on a sardine diet, suggesting that pelagic feeding resources dominate shearwater diet. However, the high level of 20:1n-11, likely metabolized from 22:1n-11 by the birds themselves, suggested that the diet also contained a demersal component rich in 22:1n-11. Contrary to the situation in the open oceans, the levels of the C20 and C22 monounsaturated fatty acids are low in the Mediterranean food web and characteristic of most demersal species. Our results support the findings of previous field studies that the diet of the shearwaters is frequently supplemented by demersal fish from fishery discards.

“…Given the strong seasonal variation in body mass, with most breeding seabirds losing considerable body mass during the breeding season , Kalmbach et al 2004, it seems likely that the adipose tissue FAS of the birds returning to the breeding colony show signs of the winter diet (Foglia et al 1994, Herzberg & Skinner 1997, Katan et al 1997. However, it could be tested by sampling FAS in the adipose tissue of species of birds that are known to switch between completely different diets in summer and winter.…”

“…Because the plasma FAS already show large changes 5 d after a switch of diet (Käkelä et al 2005), adipose tissue and muscle samples representing longer time windows were collected from fresh carcasses of dead great skuas. The turnover rates of fatty acid composition of adipose tissues vary according to metabolic status from a month to years, and are different for different fatty acids (Foglia et al 1994, Herzberg & Skinner 1997, Katan et al 1997. Thus, it is likely that at least slowly turning over components of adipose tissue FAS indicate winter diet of skuas, as these birds lose mass during the breeding season, but return to the colony in spring at heavy weights due to storage of reserves over winter (Furness 1987, Kalmbach et al 2004.…”

Fatty acid signatures (FAS) were determined in plasma and adipose tissue of great skuas Stercorarius skua from Shetland in order to test the applicability of this biomarker in estimating diets of wild scavenging seabirds. The plasma FAS were compared with those of captive herring gulls Larus argentatus, which were fed typical Northeast Atlantic demersal and pelagic fish. The individual fatty acids that showed the largest proportional changes in FAS due to changes of dietary fish in herring gulls also varied the most in wild great skuas, suggesting a dietary origin of these changes in FAS. Thus, great skuas that had recently been feeding largely on a demersal or terrestrial diet were distinguished from individuals feeding mainly on a pelagic diet. Pronounced variation in the plasma FAS of great skuas suggests either very flexible feeding behaviour or individual dietary specialisation, which concurs with previous studies based on pellets. Individuals that regurgitated pellets consisting only of demersal fish, bird or rabbit showed larger values of a specific polyunsaturated fatty acid ratio (20:4n-6/18:3n-3+18:4n-3+ 20:5n-3) than birds whose pellets also contained remains of pelagic fish. Although pellet data showed a clear dominance of demersal fish in the summer diet of the great skua, the large proportions of long-chain monounsaturated fatty acids (e.g. 20:1n-9 and 22:1n-11) in adipose tissue of the great skua suggest that a considerable part of fat accumulated outside the breeding season comes from fatty pelagic fish.

“…Among different saturated fatty acids, stearic acid is not utilized well by the chick (Carver and Johnson, 1953); while polyunsaturated fatty acid is utilized wellby the birds (Crespo and Esteve-Garcia, 2001). Differences in fat deposition as the result of different dietary oil levels was reported by Foglia et al (1994)which might be due the association with metabolic differences between chicken lines (Foglia et al, 1994). An alternative therapeutic approach exploration was explained by Marion-Letellier et al, (2013) where it was reported that, thereis an impact of fatty acid on innate immunity.…”

The study was conducted with an aim to study the animal fat as single (halal tallow) and combined state (halal tallow and haram lard combination) on growth performance, relative organ weight, cecal microbiology and noxious gas concentration in broilers on the aspect of halal ethical issue. Following completely randomized design, a total of 96 day old Ross broiler chicks were allocated into two treatments (TLO: Basal diet with tallow; TPL: Basal diet with tallow+lard), where there was six replications with eight birds per replicate pen. Feed and water was provided ad libitum with dividing starter (0 to 3 weeks) and finisher (4 to 5 weeks) period. The result revealed that, growth performancedid not differ between TLO and TPL (P>0.05); however, immunity (IgM) was higher in TLO in comparison to TPL (P<0.05). Among the internal organs, small intestine, large intestine and cecum weight was higher in TLO relative to the TPL (P<0.05).In addition, cecal and excreta pH was lower in TLO than the TPL (P<0.05); where, among cecalmicrobiology, Bacillus sp. count was higher in TLO compared to TPL (P<0.05). Excreta noxious gas concentration data revealed that, ammonia gas was lower in TLO during 0 hour, 3 hour and 12 hour incubation period, while the average value also significantly lower in TLO in relation to the TPL (P<0.05). The hydrogen sulfide and sulfur dioxide gas did not differ between TLO and TPL (P>0.05). Economic analysis data elucidated that, there was no significant difference for cost per unit of gain between TLO and TPL (P>0.05). The result suggested that, tallow and lard combination has no negative impact on the growth performance; however, there was higher excreta noxious gas concentration, which is one of the important issues for the environmental aspects from the broiler industry. Therefore, single use of animal fat (halal tallow) for halal broiler production are preferred instead of combination with another animal fat (haram lard).
