AIM This experiment was conducted to evaluate the effect of L-carnitine supplementation on growth performance, nutrient utilization and nitrogen balance in broilers fed with animal fat. MATERIALS AND METHODS 80 day-old Cobb commercial broiler chicks were randomly assigned into two dietary treatment groups with four replicates of ten chicks each. The diets were isonitrogenous and isocaloric. T...

the effects of l-carnitine on growth performance and carcass composition in male broiler chicks, fed diet in which cp was reduced in a stepwise manner from 21 to 18% were investigated. ileal digestible quantities of all eaa were almost equal in the diets, with quantities nrc 1994 recommendations. one hundred forty four male commercial broilers were allotted to six groups, each with four replica...

Three experiments using 1,356 pigs (C22 × 336 PIC) were conducted to determine the interactive effects of dietary L-carnitine and ractopamine hydrochloride (RAC) on carcass characteristics and meat quality of finishing pigs. Experiments were arranged as factorials with main effects of L-carnitine and RAC; L-carnitine levels were 0, 25, or 50 mg/kg in Exp. 1 and 2 and 0 or 50 mg/kg in Exp. 3, an...

This study was conducted to test the effects of supplemental L-Met on redox status, gut development, and growth performance of young broiler chickens compared with DL-Met. A total of 888 (half male and half female) 1-d-old Ross 308 chickens were weighed and randomly allotted to 7 treatments in a randomized complete block design for 21 d, including a basal diet (BD), the BD + 0.095% L-Met or DL-...

Gestating sows (n = 44; parity = 2.0; BW = 208 kg) were used to determine the effects of dietary L-carnitine and Cr picolinate (CrP) on daily blood hormone and metabolite profiles. Diets were formulated as a 2 x 2 factorial with L-carnitine (0 or 50 ppm) and CrP (0 or 200 ppb) and were fed from breeding through gestation, lactation, and 28 d into the subsequent gestation, at which time blood co...

This study was conducted to evaluate the effect of ractopamine, coenzyme Q and L-carnitine, 10 individually and in combination, on the hematological parameters of broiler chickens. A total of 512 one day-old male broiler chickens (Ross 308) were randomly divided to eight treatment groups. Each group had four replicates with 16 birds per each. Treatments were assigned as a 2 × 2 × 2 factorial ar...

Two experiments were conducted to evaluate the nutritional quality of 2 varieties of Purdue high-digestible sorghum (PHD1 and PHD2) and a normal sorghum, compared with corn, in diets of pigs and broiler chicks. In Exp. 1, 12 pigs (average BW, 55 kg) fitted with ileal T-cannula were fed 4 diets containing 946 g of corn or sorghum (PHD1, PHD2, and normal) per kg in a 2-period crossover design (i....

Six experiments (EXP) were conducted to evaluate growth performance of different breed crosses of broiler chicks fed diets containing soybean meal, soy protein isolate (SPI), soy protein concentrate (SPC), or rice and casein. Cornish x Plymouth Rock (C x PR; EXP 1, 3, 4, 5, and 6) or New Hampshire x Columbian (NH x C; EXP 2 and 4) cross chicks were used. The chicks were fed a corn-soybean meal ...

Two experiments were conducted to evaluate the effects of fusaric acid (FA) in broiler chicks (Exp. 1) and turkey poults (Exp. 2). In each experiment, 100 day-old birds were allotted randomly to dietary treatments containing 0, 100, 200, 300, or 400 mg FA/kg of feed. Each dietary treatment was fed to 4 pen replicates of 5 birds each for 21 days. Fusaric acid had no effect (P > 0.05) on feed int...

Two experiments were conducted to evaluate the effect of dietary L-carnitine on growth performance and body composition of early-weaned pigs. In Exp. 1, 120 weanling pigs (initially 5.6 kg and 19 +/- 2 d of age) were allotted in a 3 x 2 factorial with four pigs per pen and five replications (pens) per treatment. Main effects from d 0 to 14 after weaning included dietary L-carnitine (0, 500, or ...
