Corn Processing

Abstract The objectives of this trial were to evaluate the association between corn processing, glucose-dependent insulinotropic polypeptide (GIP) concentration, and intramuscular (IM) fat deposition. We hypothesized that steers fed whole shelled corn (WSC) would have a greater IM fat deposition than steers fed cracked corn (CC) due to an increase in plasma GIP concentration. Backgrounded, Angus-cross cattle (initial body weight [BW] = 279 ± 9.8 kg) were used in a randomized complete block design in a feedlot setting for an average of 230 d. Cattle were allotted in 12 pens (6 pens per treatment with 8 animals per pen). There were three blocks: heifers (n = 32, initial BW = 265 ± 1.3 kg), small steers (n = 32, initial BW = 262 ± 1.3 kg), and large steers (n = 32, initial BW = 310 ± 1.4 kg). Two pens within each block were randomly assigned to one of the following treatments: 1) CC or 2) WSC. Animal growth performance, carcass characteristics, and plasma hormone and metabolite concentrations were analyzed using the MIXED procedure of SAS, including the fixed effects of treatment, or treatment, time, and their interaction. Pen and block were included as random effects. Carcass yield and quality grade distributions were compared using the GLIMMIX procedure of SAS. including the fixed effects of treatment and time with pen and block as random effects. Linear regression was used to evaluate the association of plasma GIP concentration and IM fat content. Average daily gain (P = 0.57) and final BW (P = 0.34) were similar, regardless of treatment. Cattle fed CC had reduced (P < 0.01) dry matter intake (DMI) when compared with those fed WSC. This lesser DMI resulted in improved gain:feed ratio (P < 0.01) for cattle fed CC compared with cattle fed WSC. There was no effect (P ≤ 0.33) of corn processing on plasma glucose, plasma GIP concentrations, hot carcass weight, dressing percentage, or marbling score. There was a positive linear relationship (P = 0.03) between IM fat concentration and plasma GIP concentration. In conclusion, feeding CC increased gain:feed ratio compared with WSC, but there was no difference in plasma GIP concentration, whereas plasma GIP concentration appears to be related to IM fat deposition.

Crossbred Pigs

Thirty-two female crossbred pigs (initial weight 75 kg) were used in this experiment to investigate the effect of differing porcine somatotropin (pST) regimes on growth performance. Pigs were kept in individual pens and fed ad libitum a wheat-based diet formulated to contain 14.4 MJ DE/kg and 180 g ideal protein/kg. Treatments were daily injection with saline (Sal), daily injection with pST (5 mg) (D), bi-daily injection with pST (10 mg) (2D), and injection with pST (12 mg) every Monday, Wednesday, and Friday (MWF). On the days that pigs were not receiving pST they were injected with saline (0.5 mL). All pST regimes caused a reduction (P < 0.001) in feed intake and feed conversion ratio (FCR), although there was no significant effect on average daily gain. Feed intake decreased after the first injection and, for the D group, remained low and constant. Feed intake for the 2D group was also reduced but not to as great an extent as for the D group. Feed intake in the MWF group showed a clear temporal response, being low during the week but increasing over the latter part of the weekend. Thus, feed intake from Sunday until Monday mornings was 400 g greater (P < 0.001) than from Saturday until Sunday mornings. Therefore, it appears that the effects of pST on feed intake may be reduced when a 3-day interval is used between injections. Back fat was significantly reduced with all pST injection regimes, whereas estimated fat deposition was only significantly reduced in the D and 2D pigs. Plasma urea nitrogen was increased, whereas glucose was decreased during pST administration and the average concentrations of both metabolites during the first week of administration were strongly related (P < 0.001) to FCR over the full 3 weeks of the study (R = 0.733 and -0.683, respectively). Although daily injection with pST appears to give the greatest reduction in feed intake and fat deposition, an alternative pST injection regime involving less frequent pST injections can also improve growth performance similarly in finisher pigs.
