Effect of creatine addition in feeds containing animal meals on the performance and carcass yield of broilers

Abstract

The objective of this study was to evaluate the performance and carcass characteristics of broilers fed exclusively vegetable diets and diets containing animal meal with the addition of creatine or not after day 8. In the experiment, 1080 one-day-old male chicks were distributed according to a completely randomized experimental design into six treatments with six replicates each. A control diet based on corn and soybean meal was formulated, to which animal meals and creatine were included or not. Diets were formulated to contain equal mineral (calcium, phosphorus and sodium) and amino acid (available methionine + cystine, lysine and threonine) levels. The following treatments were applied: A. control (diet based on corn and soybean meal); B. control + creatine (600g/ton); C. inclusion of 5% meat and bone meal (MBM), D. inclusion of 5% MBM + creatine (600g/ton), E. inclusion of 5% blood meal (BM), F. inclusion 5% BM + creatine (600g/ton). Weight gain, feed intake, feed conversion, carcass yield and viability were evaluated. At 42 days of age, BM dietary inclusion impaired weight gain and feed conversion ratio. The inclusion of MBM affected only feed conversion ratio. The addition of creatine ito the diet with BM improved weight gain when compared with the BM diet with no creatine. The addition of creatine to the diet containing 5% BM improved weight gain when compared with the same diet without the use of the additive.

Efficacy of Zinc/Creatine Supplementation on Improving Growth Performance of Local Balady Chicks

“…Moreover, combination of Zn and CMH showed better results of the tested parameters than CMH or Zn supplementation each alone, respectively. These findings are in agreement with several reports demonstrating that CMH supplemented up to 10g/ kg diet of the broilers improved the body weight gains compared with the same diet without the use of the additive, Carvalho et al (2013). Similarly, Fawzy et al (2016) showed also that body weight gain of the birds fed with the diet supplemented with Zn (2 g /10 kg ration) were significantly higher than the control group and the feed conversion ratio was better.…”

“…Halle et al (2006) showed that supplementing CMH up to 10g/kg diet can be regarded as a method for elevating production efficiency and meat yield in broiler chickens. Carvalho et al (2013) also, reported that inclusion of CMH in the control diet also exerts an improvement in body weight gain and feed conversion ratio to broiler chicks compared with the diets with no CMH.…”

“…Moreover, all the processes of cells involved in growth and metabolism require energy. CMH supplementation is needed for mainly bodily functions concerning maintenance (i.e., ATP regeneration) and may be vital to support optimal growth (i.e., protein synthesis), Carvalho et al (2013). Halle et al (2006) showed that supplementing CMH up to 10g/kg diet can be regarded as a method for elevating production efficiency and meat yield in broiler chickens.…”

The Relationship Between Guanidino Acetic Acid and Metabolisable Energy Level of Diets on Performance of Broiler Chickens

“…Recently, positive effects on growth performance were noticed when broilers were administered GAA. The transformation of GAA into creatine was evidenced by an increase in creatine levels (in serum and muscle) (Lemme et al, 2007a(Lemme et al, , 2007bRingel et al, 2008;Michiels et al, 2012;Carvalho et al, 2013). Moreover, GAA could be beneficial in broiler diets because it may be able to spare arginine, which is considered to be the fifth limiting amino acid in typical corn-soybean diets for broilers (Baker, 2009;Waguespack et al, 2009).…”

An integrated transcriptomics and metabolomics study of the immune response of newly hatched chicks to the cytosine-phosphate-guanine oligonucleotide stimulation

“…Finally, creatine was the only metabolite upregulated by CpG-ODN at D6. It is strongly related to energy metabolism and is a key non-essential amino acid stored in muscles that have been previously associated to growth performance in broilers ( Carvalho et al., 2013 ). It seems to be a direct translation of the early increase of the metabolic activity.…”
