“…No significant effect of animal fat was reported by Crespo and Esteve-Garcia, (2001) in broiler study. Other studies also reported no significant differences between various fat sources while fed to young broilers and market broilers (Pesti et al, 2002;Firman et al, 2008). It was reported that, addition of fat usually beneficial after the first week of age (Sibbald, 1978 Dvorin et al (1998) reported that, the interaction of saturated and unsaturated fatty acid is balanced while animal fat and vegetable oils are well mixed.…”

“…High energy diets have been shown to improve growth and feed efficiency (Zaman et al, 2008;Hosseini-Vashan et al, 2010). Other benefits ofincluding the fat sources in the diet are improvement of the growth rates and feed efficiency, decrement of feed intake, source oflinoleic acid and increment of palatability of feeds (Firman et al, 2008). Fat has extra caloric effect and influence in the nutrient availability of other ingredients (Jensen et al, 1970;Horani and Sell,1977), helps to slow gut transit of other feeds, resulting in increased digestibility (Firman and Remus, 1994;Firman et al, 2008).…”

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).

“…Supporting to the present study, no significant effect of animal fat was reported by Crespo and Esteve-Garcia (2002) in broiler study. Other studies also reported no significant differences between various fat sources while added to the diet of young and finishing broilers (Pesti et al, 2002;Firman et al, 2008). In the present study, during overall period (0 to 5 weeks), weight gain and feed intake did not differ among fat treatments (although higher numerical value was exhibited in the FT1 and FT2), whereas a tendency of better feed efficiency was observed in the FT1 group than the FT3 and FT5 group, which might be attributable to the presence of more unsaturated fatty acids in the plant fats.…”

An experiment was conducted to evaluate fat sources on growth performance, excreta microbiology and noxious gas emissions in broilers. Experimental birds were reared for 5 weeks and divided into two periods: Starter (0 to 3 weeks) and finisher (4 to 5 weeks). A total of 150 one day old Ross 308 broiler chicks were randomly allocated into five treatments with five replications (six birds per replicate) following a completely randomized design. Dietary treatments included FT1 (corn-soybean meal based basal diet with soybean oil), FT2 (corn-soybean meal based basal diet with chicken fat), FT3 (cornsoybean meal based basal diet with tallow), FT4 (corn-soybean meal based basal diet with tallow and lard) and FT5 (corn-soybean meal based basal diet with pork fat/lard). Overall body weight gain and feed intake did not differ due to addition of different dietary fat sources in broiler diet; however, feed conversion ratio was better in FT1 fed group in comparison to other fat groups (P<0.10). The result of the serum immunoglobulins data indicated that, a significant elevation of serum immunoglobulin M (IgM) was observed after dietary addition of FT1, FT2 and FT5 relative to FT4 (P<0.05) Excreta pH did not differ, however, yeast and mold count was highest in FT4 and FT5 relative to FT1 and FT3 (P<0.05). Excreta noxious gas emissions (NH 3 , H 2 S and SO 2 ) were lower in FT1 and FT2 in comparison to other fat groups (P<0.05). Overall, the results of the present study suggested that FT1 and FT2 can be prioritized in the diet of broilers with positive influence on body weight gain and feed efficiency, and substantial reduction of noxious gas emissions. Further detail study could be conducted to investigate the single and combination of different dietary fats (with different ratio) on performance and meat quality indices.

The type of fat used in formulating broiler chicken diets can affect growth performance, influence the fatty acid composition of different tissues and has consequences for bird health and nutritional value for the consumer. This study aimes to address the hypothesis of whether these effects are specifically due to the variation in the fatty acid composition of the diets, that is, the proportion of different saturates, monounsaturates (n‐7 and n‐9) or polyunsaturates (n‐3 or n‐6), or other factors (physical properties, solid/liquid and source, plant/animal). A total of 480 male Cobb 500 broilers are fed ad libitum on one of six diets containing 4% w/w of either: beef tallow, flaxseed, corn, canola, macadamia, or coconut oil (eight replicates/treatment) for 6 weeks. At harvest, there are no significant differences in productivity parameters nor in the crude lipid content of different tissues between dietary treatments. There are, however, substantial qualitative differences in the fatty acid profiles of all tissues. The levels of specific fatty acids in all tissues except the brain, are positively correlated with the levels of the same fatty acids in the diet however, the strength of the correlations varied between different fatty acids. Practical Applications: The results of the current study demonstrate that the dietary fatty acids types and proportions largely determines the fatty acid profile in edible tissues (meat, adipose, liver, and heart). The strong correlations and regressions between diet and tissue fatty acid levels validate the ability to predict the tissue fatty acid profile of broilers based on their dietary fat composition. Contrary to our hypothesis, dietary fat type had no influence on the growth parameters which makes us speculate whether such differences in similar studies only become apparent in situations where the birds are also under some level of environmental or social stress. This information will assist poultry feed manufacturers and broiler producers in making decisions about selection of fats with known nutritional and health benefits for inclusion in chicken feed. The relationship between the diet and breast meat fatty acid composition of 6‐week‐old male broilers (Cobb 500) fed diets containing 4% w/w of either tallow, flaxseed oil, corn oil, canola oil, macadamia oil, or coconut oil. Dietary fatty acid intake determined breast meat fatty acid composition with a strong positive linear correlation for 6 all fatty acid groups (saturates, omega‐9 and omega‐7 monounsaturates, omega‐3, and omega‐6 polyunsaturates and trans, R = 0.938–0.999, P < 0.01).
