Influence of Dietary Fat Source on Growth Performance Responses and Carcass Traits of Broiler Chicks

Abstract

This study was conducted to determine the effects of three different fat sources and their combination on growth performance, carcass traits and intestinal measurements of broiler chickens reared to 42 d of age. Two hundred day-old male broiler chicks (Ross 308) were randomly assigned to one of five treatments with four replicates of 10 chicks based on a completely randomized design. The dietary treatments consisted of 4% added fat from three different sources and their combination as follows: T, diet containing 4% tallow; CO, diet containing 4% canola oil; SFO, diet containing 4% sunflower oil; TCO, diet containing 2% tallow+2% canola oil; TSFO, diet containing 2% tallow+2% sunflower oil. Dietary fat type affected significantly BW and gain as well as feed efficiency in birds fed the TCO diets compared with those fed the other diets. Dietary fat type also modified meat yield, resulting in a higher breast and drumstick yields in the birds fed TCO and TSFO diets, respectively. Most of internal organ relative weights and small intestine measurements were not influenced by dietary treatments, except for the abdominal fat pad weight that was lower in birds fed SFO and for small intestinal length that was influenced by fat source. Results from the current study suggested that the supplementation with a combination of vegetable and animal fat sources in broiler diet supported positively growth performance and carcass parameters.

Effects of feeding different lipid sources on hepatic histopathology features and growth traits of broiler chickens

“…The present findings demonstrates the favourable effect in supplementing EVOO compared to lipids of animal origin as dietary energy source in poultry. Moreover, variations in responses of randombred and modern-type broiler strains to supplemented lard in diet could be a result derived by the genetic selection (Poorghasemi et al, 2013).…”

“…Previous investigations have demonstrated that broilers have the ability to use considerable levels of dietary fat as energy source; on the other hand, the efficiency of its utilization mostly depends on the fatty acids composition (Zduńczyk et al, 2001;Saraee et al, 2015). It was reported that fats of animal origin high in saturated fatty acids are not easy to digest in poultry digestive system when compared to unsaturated oil from vegetables (Poorghasemi et al, 2013). The significance of fats from different sources in poultry nutrition is studied not only from a productive point of view, but also in relation to human nutrition and wellbeing.…”

Effects of dietary oil sources, calcium and phosphorus levels on growth performance, carcass characteristics and bone quality of broiler chickens

“…It is recommended that when high levels of fat are used in poultry diets, calcium and magnesium levels should be increased (Hakansson 1975). Although some researches have been conducted on the effect of dietary oil and National Research Council (NRC) calcium requirement on broiler performance and carcass quality characteristics (Maroufyan et al 2012;Poorghasemi et al 2013), information on the effect of dietary oil sources and different levels of calcium is very limited. Thus, the objective of this study was to determine the effect of soybean oil (SO), linseed oil (LO) and palm oil (PO) each at 6% with different levels of calcium and phosphorus on the growth performance, bone quality and carcass characteristics of broiler chicken.…”

Unsaturated to Saturated Fatty Acids Ratio Adjustmentin Diets on Digestibility and Performance of Growing Pigs

“…Jung et al (2003) found that the replacement of animal fat with vegetable oil rich in unsaturated fatty acids, such as soybean oil or corn oil, resulted in an improved growth performance in weaning pigs. Results from the poultry model reported that an optimal combination of vegetable oil and animal fat sources in broiler diets enhanced growth performance and carcass traits (Poorghasemi et al, 2013).…”
