Effects of dietary supplementation with creatine monohydrate during the finishing period on growth performance, carcass traits, meat quality and muscle glycolytic potential of broilers subjected to transport stress

Abstract

A total of 320 male Arbor Acres broiler chickens (28 days old) were randomly allotted to one of the three experimental diets supplemented with 0 (160 birds), 600 (80 birds) or 1200 mg/kg (80 birds) creatine monohydrate (CMH) for 14 days. On the morning of 42 day, after an 8-h fast, the birds of CMH-free group were divided into two equal groups, and all birds of these four groups were transported according to the follow protocol: 0.75-h transport without CMH supplementation (as a lower stress control group), 3-h transport without CMH supplementation, 3-h transport with 600 or 1200 mg/kg CMH supplementation. Each treatment group was composed of 8 replicates with 10 birds each. The results showed that supplementation of CMH for 14 days before slaughter did not affect the overall growth performance and carcass traits of stressed broilers (P>0.05). A 3-h transport decreased plasma glucose concentration, elevated plasma corticosterone concentration, increased bird live weight loss, breakdown of muscle glycogen, as well as the accumulation of muscle lactate (P<0.05), which induced some detrimental changes to breast meat quality (lower ultimate pH and higher drip loss, P<0.05). Nevertheless, supplementation of 1200 mg/kg CMH reduced chicken weight loss, decreased the contents of lactate and glycolytic potential in pectoralis major of 3-h transported broilers (P<0.05), which is beneficial to maintain breast meat quality by reducing the drip loss (P<0.05). These findings suggest that the reduction of muscle glycolysis is probably the reason for maintainance of meat quality by supplementation of CMH in transported broilers.

“…On the other hand, Berri et al, (2005), studying the effect of the stress of the activity on the slaughter line preceded or not by heat exposure, found that drip loss was more important in the stressed chickens of which pHu was relatively lower. Schneider et al, (2012) and Zhang et al, (2014) also reported lower drip loss when the pH was higher.…”

“…According to Berri (2015), the ultimate pH depends on the glycogen concentration of the muscles at the slaughter time. Transportation for 3 hours decreases the plasma glycogen concentration in broilers (Zhang et al, 2014). Animal's disturbance lead to the depletion of muscle glycogen content and then to a higher meat pH (Cartier and Moëvi, 2007).…”

Effect of dietary resveratrol supplementation on meat quality, muscle antioxidative capacity and mitochondrial biogenesis of broilers

“…Cooking loss was expressed as the weight change percentage of the sample before and after cooking. The cooked sample was manually trimmed into rectangular shaped strips (3.0 cm long, 1.0 cm wide and 1.0 cm thick) parallel to the longitudinal axis of the myofibers and then used for shear force value measurement in triplicate using a TMS‐Pro texture analyzer (Food Technology Corporation Co., Sterling, VA, USA) with a load cell of 100 N and a crosshead speed of 150 mm min −1 according to a previously described procedure …”

“…Therefore, there is a growing interest among producers and scientists to explore effective ways to improve chicken meat quality for meeting the demand of consumers. Numerous studies have indicated that dietary supplementation with certain nutrients, for example creatine monohydrate, curcumin, vitamin E and Echinacea purpurea L., is a possible effective means of improving chicken meat quality.…”

“…The synthetic product Cr monohydrate (CrMH), the primary dietary additive form of Cr (Jäger, Purpura, Shhao, Inoue, & Kreider, ), has been intensively studied and described as a dietary additive for humans and livestock animals (Harris & Lowe, ; Lowe, Murphy, & Nash, ; Persky & Brazeau, ; Zhang et al, ). Due to the instability of CrMH in aqueous and acidic solutions as well as at high temperatures yielding the physiologically inactive degradation product Crn (Cannan & Shore, ; Hahn & Bakan, ; Jäger et al, ), its use as a direct animal feed additive is limited (Baker, ).…”
