“…Groups of three birds were then randomly assigned to 12 cages. All birds were allowed a 4-day adaptation period where they were fed a corn-soybean based diet with 30% CM to eliminate the carry-over effects between the diets (Kadim et al, 2002;Soleimani et al, 2010). Following the adaptation period, the birds were fasted for 24 h to remove gastrointestinal con-tent.…”

The aim of the current study was to determine the effect of extrusion process on apparent metabolizable energy (AME), crude protein (CP) and amino acid (AA) digestibility of canola meal (CM) in broiler chickens. A total of 36, 42-day-old broilers were randomly assigned into adaptation diets (no CM or 30% CM) with six replicates. After 4 days of adaptation period, on day 47, birds were allowed to consume the assay diets that contain CM or extruded canola meal (ECM) as the sole source of energy and protein.Following 4 h after feeding, the birds were killed and ileal contents were collected. The results showed that ECM had greater (P<0.001) AME (10.87 vs 9.39 MJ/kg) compared to CM. The extrusion also significantly enhanced apparent ileal digestibility of CP and some of AA such as Asp, Glu, Ser, Thr and Trp. In conclusion, the extrusion treatment appeared to be a practical and effective approach in enhancing the digestibility of AME, CP and some AA of CM in broiler chickens.

“…Maintaining normal body temperature during HT is a challenge for poultry as they lack sweat glands, relying on evaporative cooling (panting) to keep cool (Marder and Arad, 1989). There are plethora of reports referring to increased body temperature in chickens during HT (Yahav and Hurwitz, 1996;Chowdhury et al, 2012a, b;Ito et al, 2014) and this may cause heat stress (Soleimani et al, 2010).…”

Oral Administration of L-Citrulline, but not L-Arginine or L-Ornithine, Acts as a Hypothermic Agent in Chicks

et al. 2015

Some amino acids are important regulators of key metabolic pathways and necessary for several physiological functions. However, little is know about thermoregulatory functions of amino acids. In this study, therefore chicks were either centrally or orally administered with L-citrulline (L-Cit), L-arginine (L-Arg) or L-ornithine (L-Orn) to monitor changes in rectal temperature. In Experiment 1, the amino acids (L-Cit, L-Arg and L-Orn) were administered into the left ventricle of the chicks by intracerebroventricular (i.c.v.) injection at a dose of 1 μmol/10 μl to monitor the effects of these amino acids on rectal temperature during 120 min of the experimental period. In Experiment 2, chicks received the same amino acids by oral administration at a dose of 15 mmol/10 ml/kg body weight. In Experiment 3, chicks received three doses of L-Cit (3.75, 7.5 or 15 mmol/10 ml/kg body weight) by oral administration. I.c.v. injection with any of the amino acids studied did not alter body temperature, but oral administration of L-Cit significantly reduced body temperature. Importantly, the highest does effectively reduced body temperature. These results suggest that peripheral L-Cit has a hypothermic function in chicks, which may be a new candidate to minimize high body temperature in poultry during summer heat stress.

All birds were allowed a 4-day adaptation period where they were fed a corn-soybean based diet with 30% CM (basal diet, Table 1) (Soleimani et al, 2010). Two experimental diets containing either CM or fermented CM (FCM) as the sole source of energy and protein were prepared (Table 1) (Ahmed et al, 2014;Jia et al, 2012).…”

The aim of the current study was to investigate the potential of Lactobacillus salivarius solid state fermentation for reduction of glucosinolate content in canola meal (CM) as well as the improvement of its nutrient digestibility for broiler chickens. Canola meal was treated with the L. salivarius in solid state fermentation for 30 days. Nutrients ileal digestibility was tested using 42-day-old broilers fed by either CM or fermented CM (FCM) as the sole source of energy and protein. The results showed that fermentation of CM using L. salivarius reduced glucosinolate content of CM by 38%. The digestibility coefficient was improved significantly for crude protein, Met, Cys, Arg, Asp, Glu, and Ser in FCM compared to CM. However, apparent metabolisable energy of CM was not affected by fermentation. It appears that fermentation treatment of CM using L. salivarius may improve the overall nutritive value of CM for broiler chickens, reducing its total glucosinolate and crude fibre content by 38 and 16%, respectively.
