Reducing limitations in intracellular energy metabolism and improving the cellular energy homeostasis can maximize the feed utilization efficiency of broilers. Optimizing the creatine stores by supplementation of Guanidinoacetic Acid (Creamino®) can maximize performance. Could you improve profitability of production through Creamino® on top application or energy sparing effect? This might be a valuable contribution to reduce the impact of currently skyrocketing feed prices on production cost of broilers.
|The objective of this study was to evaluate if the supplementation of GAA on top or with an energy matrix manages to improve or equalize the productive and economic parameters in broilers.
The study was carried out in the experimental farm of the Italcol Company located in the department of Santander, Colombia, and lasted for 35 days. 1088 Ross 308 AP one day old male chickens with an initial weight of 42.5 ± 1.05 grams, were used and divided into 4 treatments with 8 repetitions of 34 chickens per treatment. The experimental design was completely randomized. The treatments were: Control based on breeder’s recommendations; Negative Control (- 80 kcal during starter and fattening phases); Control + 0.06% Creamino® (GAA on top); Negative Control + 0.06% Creamino® (GAA matrix). The feeding consisted of 3 phases: A pre-starter, a starter and a fattening phase. The following production figures were evaluated: live weight, feed consumption, feed conversion and European Efficiency Index (EEI).
Overall, the results indicated that at day 35, when we compared the group supplemented with 0.06% of GAA considering an energy matrix of 80 kcal with the Control group, we found that the GAA matrix group gained 21 grams more per chicken, 2 points less in feed conversion and 2% improvement in EEI. When we compared the group supplemented with 0.06% of GAA on top with the control group, we found that the GAA group obtained 59 grams more per chicken, 4 points less in feed conversion and 4% improvements in EEI.
In conclusion, the use of GAA both matrixed at 80 kcal and on top, improves the productive and economic efficiency in broilers at 35 days of age.
