Partial Replacement of Animal Fat with Full-Fat Almond in Broiler Chicken Diets: Performance, Nutrient Digestibility, Blood Profile, Cecal-Fecal Microflora Composition, and Foot-Pad Dermatitis
The purpose of this study was to evaluate the effect of full-fat almonds (FFA) as an alternative protein and fat source for broiler feed on broiler productivity, nutrient digestibility, blood characteristics, cecal-fecal microflora, and foot-pad dermatitis (FPD). A total of 96, one-day-old broiler c...

| Sumario: | The purpose of this study was to evaluate the effect of full-fat almonds (FFA) as an alternative protein and fat source for broiler feed on broiler productivity, nutrient digestibility, blood characteristics, cecal-fecal microflora, and foot-pad dermatitis (FPD). A total of 96, one-day-old broiler chickens (Arbor Acres) with initial body weight 41.61 ± 0.36 g were placed in 16 cages. In each trial, four treatments were set up: a basal diet partially replacing animal fat with FFA 0% (Control, CON), a basal diet partially replacing animal fat with FFA 1% (T1), a basal diet partial replacing animal fat with FFA 2% (T2), a basal diet partially replacing animal fat with FFA 4% (T3). The experiment was conducted for a total of 4 weeks. Feed conversion ratio (FCR) was higher (<i>p</i> < 0.05) in the T3 group of broilers at weeks 0 to 1 than in the CON group of broilers. From weeks 3 to 4, and for the entire experimental period, FCR was lower (<i>p</i> < 0.05) in the T3 group of broilers than in the CON and T1 groups of broilers. The apparent ileal digestibility (AID) of the ether extract (EE) was higher (<i>p</i> < 0.05) in the T3 group than in the other treatment groups, and AID of crude protein (CP) was higher (<i>p</i> < 0.05) in the T3 group than in the CON group. The apparent total tract digestibility (ATTD) of EE was lower (<i>p</i> < 0.05) in the CON group than in the other treatment groups, and the ATTD of CP and energy was higher (<i>p</i> < 0.05) in the T3 group of broilers than in the CON group of broilers. The AID and ATTD of total amino acids were higher (<i>p</i> < 0.05) in the T3 group than in the other treatment groups. Blood cholesterol levels were lower (<i>p</i> < 0.05) in the T3 group of broilers than in the CON and T1 groups of broilers, and higher (<i>p</i> < 0.05) in the CON group of broilers than in the T2 and T3 groups of broilers. The amount of <i>E. coli</i> in the cecal and fecal was lower (<i>p</i> < 0.05) in the T3 group than in CON and T1 groups. FPD score was higher (<i>p</i> < 0.05) in the T3 group of broilers than in the CON group of broilers. In conclusion, replacing a partial of animal fat with at least 4% FFA in broiler diets can increase growth performance and nutrient digestibility in broiler nutrition. |
