Abstract The effect of corn distillers dried grains with solubles (DDGS), used in grower-finisher diets with or without supplemental enzymes, on growth performance and carcass and meat quality was determined in an experiment with 48 pigs. Group I (control) received a standard grain-soybean meal mixture without DDGS and without enzymes; Group II was fed a mixture containing 15% (grower) or 20% (finisher) of corn DDGS but without the enzymes; Group III received a mixture containing 15% (grower) or 20% (finisher) of corn DDGS with NSP-hydrolyzing enzymes (200 g t-1). The feed mixtures were isonitrogenous and isoenergetic. All pigs were fattened from 30 to 112 kg. At the end of the experiment all pigs were slaughtered, right carcass sides were evaluated and samples of longissimus muscle were taken for analysis. Inclusion of corn DDGS did not significantly affect pig fattening results and meat quality. The addition of NSP-hydrolyzing enzymes to feed mixtures containing corn DDGS tended to positively influence pig performance. The carcasses of pigs receiving the diet with corn DDGS and NSP-hydrolyzing enzymes were characterized by thinner backfat and greater weight of the primal cuts.

Abstract The aim of this study was to evaluate the effect of the inclusion level of crude glycerin from palm oil in the diet of growing pigs. Diets were formulated to be isocaloric and isoproteic, with a constant content of linoleic acid within the experimental diets. A total of 36 pigs (average BW 23.05± 2.86 kg) were randomly assigned to one of the three treatments: 1) 0% of crude glycerin; 2) 5% of crude glycerin; 3) 10% of crude glycerin. Pigs were housed in 12 pens; 4 replicates (pens) per treatment and three pigs/replicate. Data were analyzed as a complete block design using the GLIMMIX procedure of SAS, with a random block effect for period. This study established that inclusion of crude glycerin from palm oil in the diet of growing pigs did not affect (P > 0.05) growth performance, carcass characteristics and meat quality. We concluded that inclusion of crude glycerin from palm oil up to 10% of the diet did not adversely affect pig performance and the quality of the meat.

Abstract Two experiments evaluated the effects of removing corn DDGS from diets at increasing intervals before harvest on finishing pig performance and carcass characteristics. For Exp. 1, 985 pigs [PIC TR4×(Fast LW×PIC L02); initially 99 kg BW] were used in a 28-d study. There were 12 pens/treatment and four treatments decreasing in duration of DDGS withdrawal before marketing: 28, 21, 14, or 0 d. All pens were marketed by removing the 17% heaviest pigs on d -21 with remaining pigs marketed at final barn dump (d 0). Overall, there was no evidence for effects of DDGS withdrawal on final BW, ADFI, or G:F (P > 0.112); however, as withdrawal time increased, ADG increased (linear, P = 0.022) and iodine value (IV) decreased (linear, P = 0.001). There was no evidence for differences for HCW or loin depth (P > 0.106); however, yield increased (linear, P = 0.001) with increasing withdrawal time. Backfat depth decreased (quadratic; P = 0.019) and percentage lean increased (quadratic; P = 0.033) as DDGS withdrawal time increased. In Exp. 2, 1,158 pigs (initially 105 kg BW) were used in a 35-d study. There were 15 pens/treatment and four treatments decreasing in duration of DDGS withdrawal: 35, 28, 14, or 0 d. All pens were marketed by removing the 15% heaviest pigs on d -28, the 28% next heaviest pigs on d -14, with final barn dump of approximately 57% of starting inventory (d 0). There was no evidence that final BW, overall ADG, or G:F differed across treatments with increasing DDGS withdrawal times (P > 0.116). Overall ADFI increased (linear, P = 0.015) as time withdrawn from DDGS increased. Iodine value decreased (linear; P = 0.001) and yield increased (linear; P = 0.034) with increasing withdrawal time, with no evidence for differences in HCW, backfat, loin depth, or percentage lean (P > 0.05). These experiments suggest that longer withdrawal of DDGS prior to marketing improves carcass yield and decreases IV.

Abstract The aim of this study was to investigate the impact of slaughter weight and sex on slaughter traits and meat quality of Zlotnicka Spotted x Duroc (ZS×D) hybrid fatteners. The material comprised 56 Zlotnicka Spotted × Duroc fatteners (28 barrows and 28 gilts) which were fattened to 245th day of life. Pigs were divided into the following three groups: Group I (n=16) <110 kg; Group II (n=23) ≥110 ≤120 kg, and Group III (n=17) >120 kg. The obtained results revealed influence of the final body weight on slaughter trait values with the exception of meatiness. Fatteners from the group with the highest weight were characterised by the thickest backfat as well as by the greatest height of the loin eye. Slaughter weight exerted a significant impact on protein content, water absorbability as well as on the pH of the longissimus thoracis et lumborum (LTL) muscle. As to the influence of sex on slaughter traits, it was found that gilts were characterised by smaller backfat thickness and higher carcass meatiness than barrows. On the other hand, no effect of the slaughter weight and sex on colour parameters and sensory quality of the LTL muscle was ascertained. All the examined parameters were at high level in all slaughter weight and sex groups. The obtained results suggest that the slaughter of ZS×D crossbreds in groups I and II exerts a beneficial influence on slaughter trait levels and, at the same time, allows maintenance of high meat quality.

Abstract The objective of this study was to investigate the effect of the range of pH decline from 45 min to 48 h after the slaughter on the quality of meat in (Landrace × Yorkshire) × Hampshire fattening pigs. The mean value and standard deviation for the range of pH fall from 45 min to 48 h postmortem served to create the following experimental groups: group I with pH decline less or equal to 0.88 units pH; group II with pH decline higher than 0.88 but lower than 1.26 pH units; and group III where pH decline was equal to 1.26 units or higher. This investigation showed that glycolytic resources in meat (glycogen and lactate) were connected with the range of pH decline from 45 min to 48 h postmortem. The different ultimate pH in meat with the same lactate concentration was noted (group I vs. II). Although the range and the rate of pH decline from 3 h postmortem was higher and significantly faster (P≤0.05 and 0.01) in both groups with a higher pH fall (groups II and III), there was no statistically confirmed influence of the investigated range of pH fall on drip loss and on colour. The average values for drip loss and colour obtained in this experiment were related to ultimate pH of meat of (L × Y) × H fatteners, being characteristic for acid meat

In this trial we aimed to assess the effects of dietary supplementation of 4-O-methyl-glucuronoarabinoxylan (4OMG) on growth performance, thigh meat quality and small intestine development of female Partridge-Shank broilers. A total of 240 1-day-old female Partridge-Shank broilers were randomly distributed to four groups with three replicates of 20 within each group. Groups received either 0, 15, 20 or 25 g 4OMG/kg DM of diet. During the whole experiment of 60 days, broilers had ad libitum access to water and feed. At pen level, feed intake was recorded daily and broilers were weighed at the start and end of the experiment. For each group, three pens with a total of 20 broilers were randomly selected to determine the thigh meat quality and the small intestine development of broilers. Broilers fed diets with higher 4OMG had greater final liveweight (P = 0.004), daily bodyweight gain (P = 0.004) and gain-to-feed ratio (P &lt; 0.001), muscle pH values (P = 0.031) and redness (P = 0.001), duodenal weight index (P = 0.042), jejunal (P = 0.043) and ileal length (P = 0.049), duodenal (P &lt; 0.001) and ileal villus height (P = 0.008), but lower percentage of dead birds (P &lt; 0.001), drip loss (P = 0.042) and shear force value (P = 0.043) of the thigh muscles. These results indicate that increasing dietary supplementation of 4OMG may improve growth performance and meat quality of female Partridge-Shank broilers through better development of small intestine.
