Effect of conditioning temperature on pellet quality, performance, nutrient digestibility, and processing yield of broilers
SUMMARY: The objectives of this experiment were to evaluate the effect of conditioning temperature on broiler performance, nutrient digestibility, and processing yield from 15 to 49 d of age. A total of 1,120 Ross 708 broilers were randomly distributed among 4 treatments with 10 replicate pens and 2...

| description | SUMMARY: The objectives of this experiment were to evaluate the effect of conditioning temperature on broiler performance, nutrient digestibility, and processing yield from 15 to 49 d of age. A total of 1,120 Ross 708 broilers were randomly distributed among 4 treatments with 10 replicate pens and 28 birds/pen. Treatments consisted of diets subjected to one of 4 conditioning temperatures (71, 77, 82, and 88°C). A common starter was fed as crumbles from 1 to 14 d of age, whereas experimental grower and finisher feeds were fed as whole pellets from 15 to 49 d of age. Titanium dioxide (TiO2) was added as an indigestible marker (0.5%) during the grower phase (15–28 d) to determine nutrient digestibility. Feed intake (FI), BW gain, and FCR were determined at 14, 28, and 49 d of age. At 50 d, 10 birds/pen were randomly selected and processed for yield determination. Data were analyzed using ANOVA procedure and means were separated by Tukey HSD test. Increasing conditioning temperature from 71 to 88°C improved (P < 0.05) pellet durability and reduced percentage of fines by 9.73 and 8.78%, respectively. Conditioning temperature did not influence growth performance parameters. Increasing conditioning temperature from 71 to 82°C reduced (P < 0.05) crude protein digestibility and ileal digestible energy (IDE) by 6.41%, and 90 kcal/kg, respectively. Growth performance parameters of broilers were unaffected by conditioning temperatures notwithstanding its effect on feed quality and nutrient digestibility. |
