摘要

An experiment was conducted to evaluate the effects of corn protein concentrate (CPC) levels on performance, nitrogen digestibility, blood parameters, and visceral organ mass by newly weaned piglets. Forty piglets (6. 9 kg ± 1.2 kg of live weight) were allotted to 4 dietary treatments in a completely randomized block design. Piglets were fed individually 1 of 4 experimental diets containing different CPC levels (0%, 5%, 10% or 15%) during 44 d. Performance parameters were measured weekly. Total fecal and urine samples were collected on d 33 of the experiment for 4 consecutive days to determine N balance. At the end of the feeding period, blood samples were collected to measure blood parameters, and animals were slaughter to determine visceral organ mass. Data were analyzed as a randomized complete block designed using PROC MIXED in SAS. Final BW tended to decrease linearly (P = 0.065) as dietary CPC level increased. Overall, ADG tended to decrease linearly (P = 0.065), and ADFI was significantly reduced (P = 0. 038) as dietary CPC level increased. Nevertheless, FCR was not by dietary treatment (P = 0.1872). There were no differences on nitrogen intake, retention and digestibility across dietary treatments (P > 0. 407). However, there was a tendency to decrease linearly N excretion on urine as CPC increased in the diet. Hematocrit and Serum Urea-N were linearly increased and reduced, respectively as CPC increased in the diet (P < 0. 027). Empty BW at d 44 tended to linearly reduce as CPC increased. Pancreas weight was reduced by inclusion of CPC (linearly; P = 0. 005). In summary, it was demonstrated that, when CPC replaced partially traditional protein sources up to 5% of the diet, performance and N status of the animal are not altered. However, caution should be taken with higher levels of inclusion.
