The Individual

Abstract Feed additives are commonly used in finishing pig diets to improve growth performance and carcass characteristics; however, data is limited on the interaction of various feed additives. The objective of this study was to determine the individual and combined effects of a phytogenic feed additive (Aromex® Pro) and narasin (Skycis®) on finishing pig growth performance and carcass characteristics. The study was conducted at a commercial research facility using a RCBD with 4 dietary treatments: Control (no Aromex® Pro or Skycis®); Aromex (as Control with 90.7 g/ton Aromex® Pro); Skycis (as Control with 13.6 g/ton Skycis®); Aromex + Skycis (as Control with 90.7 g/ton Aromex® Pro and 13.6 g/ton Skycis®). Diets were based on corn, soybean meal, and corn germ meal and were fed using a 3-phase program. Diets were formulated to the same nutrient levels across treatments that met or exceeded nutrient recommendations (NRC, 2012), with the feed additive added at the expense of corn. Pigs were placed on test at 40.6 ± 4.7 kg and harvested in 2 equal groups at 122.4 ± 2.2 kg. Thirteen blocks were used with pens of 34 pigs for 1,768 total pigs. Data were analyzed using PROC MIXED of SAS with pen as the experimental unit, fixed effect of treatment, and random effect of block. There was no effect (P > 0.05) of treatment on start or end weights, overall ADG (live or carcass weight), overall ADFI, or any carcass characteristics. Overall G:F (live and carcass weight) for Aromex and Skycis was similar (P > 0.05) to each other and greater (P < 0.05) than Control. Aromex + Skycis had G:F (live and carcass weight) similar to Control and Aromex, but less than Skycis. In conclusion, including Aromex® Pro and Skycis® in finishing diets improved feed efficiency, but those effects were not additive.

Abstract Two studies were conducted to evaluate narasin inclusion level on the growth performance and carcass characteristics of growing-finishing pigs. The studies were carried out using a randomized complete block design with three narasin levels: 0 vs. 15 vs. 20 mg/kg. Study 1 (2,232 pigs) was carried out over a fixed time of 85 days from 33.4 ± 1.7 kg to 117.0 ± 2.6 kg. Study 2 (1,125 pigs) was carried out over a fixed time of 113 days from 28.0 ± 2.2 kg to 124.4 ± 6.0 kg. All pigs were fed diets that met or exceeded nutrient recommendations of growing-finishing pigs (NRC, 2012). Pigs were offered ad libitum access to feed and water throughout the study and weighed on day 0, 28, 56, and 84. Feed additions and feed remaining in the feeder at the time of pig weighing was recorded. Due to disruptions at the slaughter facility, carcass data were not collected on Study 1. For Study 2, pigs were sent for slaughter over five weeks, with the heaviest 20% of each pen being sent for slaughter each week. At slaughter, hot carcass weight was collected. Compared to controls, feeding 15 mg/kg narasin increased (P < 0.05) final body weight (1.2 kg and 1.4 kg for Study 1 and 2, respectively), increased (P < 0.05) hot carcass weight (1.3 kg), and tended (P = 0.07) to improve carcass yield (0.3 percentage units). Feeding 20 mg/kg narasin increased (P < 0.05) overall G:F compared to controls (1.5% and 1.9% for Study 1 and 2, respectively). There were limited differences between the 15 and 20 mg/kg narasin levels. The results of this study confirm improvements in growth performance and carcass characteristics from feeding narasin to growing-finishing pigs. The outcomes of feeding 20 mg/kg narasin were unexpected and warrant further research.

Abstract The objective of this study was to determine the effect of increasing dietary synthetic amino acids L-Lysine HCl, L-Threonine, Alimet®, and L-Tryptophan inclusion level at the expense of soybean meal on growth performance during the grow-finish period (46.2 ± 0.55 to 127.4 ± 0.83 kg BW) and carcass characteristics of pigs reared under commercial conditions. The study used a RCBD with 2 dietary treatments: 1). Control: 0.309, 0.029, 0.028, and 0.000 g/kg of synthetic lysine, methionine, threonine, and tryptophan, respectively; 2). High Inclusion: 0.422, 0.069, 0.047, and 0.014 g/kg, respectively. Diets were corn-soybean meal based with DDGS (20.6% for both diets) formulated to be isocaloric and to the same SID amino acid levels but varied in soybean meal inclusion (14.1 and 10.2%, for the Control and High Inclusion, respectively) and crude protein content (17.7 and 16.4%, respectively). A total of 3,520 barrows and gilts were used, housed in single-sex pens of 32 (22 replicates) at a floor space of 0.67 m2/pig. Pigs had ad libitum access to feed and water throughout the study. Pen was the experimental unit and data were analyzed using PROC MIXED of SAS; the model accounted for fixed effect of dietary treatment and the random effect of block. There was no effect of dietary treatment on final live weight, overall ADFI, hot carcass weight, backfat depth, or longissimus muscle depth. However, the High Inclusion treatment had lower overall ADG (P ≤ 0.01) and overall G:F (P ≤ 0.05), but greater (P ≤ 0.01) carcass yield than the Control treatment. These results suggest that increasing the inclusion of synthetic amino acids in corn-soybean and DDGS based diets for growing-finishing pigs to the levels evaluated negatively impacted growth rate and feed efficiency but increased carcass yield.

This experiment was conducted to evaluate the effects of supplementing 10% or 15% of baobab seed cake (BSC) or macadamia oil cake (MOC) in fattening diets for lambs on feed intake, growth performance and carcass characteristics. Thirty-two lambs aged between 150 and 180 days were randomly allocated to 4 diets (10% MOC; 15% MOC; 10% BSC and 15% BSC diets) in an experiment arranged as a 2x2 factorial design and sex as a block. The results showed that there were significant protein source and inclusion level interactions on average daily feed intake, average daily gain, and total weight gain, warm and cold carcass mass. Males were significantly superior in all parameters except for feed conversion ratio, dressing percentage and rib-eye area. It was concluded that 10% MOC and 15% BSC can be incorporated in diets for fattening of growing South African Mutton Merino lambs without compromising on their growth performance and carcass characteristics.

The Difference

ABSTRACT A total of 1,890 growing-finishing pigs (PIC; 359 × 1050; initially 27.1 kg) were used in a 124-d growth trial to compare the effects of high-protein distillers dried grains [HPDDG; 39% crude protein (CP)] or conventional distillers dried grains with solubles (DDGS; 29% CP) on growth performance and carcass characteristics. Treatments were arranged in a 2×2 + 1 factorial with main effects of distillers dried grains source (conventional DDGS or HPDDG) and level (15 or 30%). A corn-soybean meal-based diet served as the control and allowed linear and quadratic level effects to be determined within each distillers dried grains (DDG) source. All diets were formulated on an equal standardized ileal digestible (SID) Lys-basis with diets containing HPDDG having less soybean meal than diets with conventional DDGS. Pens were assigned to treatments in a randomized complete block design with initial weight as the blocking factor. There were 27 pigs per pen and 14 pens per treatment. Overall, increasing conventional DDGS decreased (linear, P < 0.04) final body weight (BW), whereas increasing HPDDG tended to decrease (linear, P = 0.065) final BW. The decreased final BW was a result of decreased (linear, P < 0.01) ADG in the grower phase of the study as either DDG source increased. However, there were no differences observed in the finisher phase or overall ADG between pigs fed either DDG source or either inclusion level. Pigs fed HPDDG had decreased (P < 0.001) ADFI and increased (P < 0.001) G:F compared with those fed conventional DDGS. For carcass traits, increasing either conventional DDGS or HPDDG decreased carcass yield and HCW (linear, P < 0.02); however, there were no differences between pigs fed HPDDG or conventional DDGS. Iodine value (IV) increased (linear, P < 0.02) with increasing DDG and was greater (P < 0.001) in pigs fed HPDDG than conventional DDGS. In summary, pigs fed HPDDG had no evidence of difference in overall ADG compared to pigs fed conventional DDGS, but had greater overall G:F. Carcass fat IV was also greater in pigs fed HPDDG compared with pigs fed conventional DDGS. These differences were probably due to the difference in oil content.
