“…Previous research indicates that raw soybeans (RSB) contain antigrowth factors that retard growth in swine (Robison, 1930;Jimenez et al, 1963;Hooks et al, 1965Hooks et al, , 1967aCombs et al, 1967;Sheppard et al, 1967;Young, 1967Young, , 1969Combs and Wallace, 1969;Jensen et al, 1970Jensen et al, , 1971Young et al, 1970;Hanke et al, 1972;Yen et al, 1974Yen et al, , 1977. Osborne and Mendel (1917) demonstrated that heating RSB destroyed the antigrowth factors.…”

An experiment was conducted to determine the influence of feeding ground raw soybeans to swine during gestation on reproductive performance for three consecutive parities. Sixty crossbred gilts were bred and randomly assigned to two dietary treatments with 30 gilts/treatment. The diets were formulated to contain 14% crude protein with either soybean meal (SBM) or raw soybeans (RSB) serving as the source of supplemental protein. All animals were fed in individual gestation stalls and were given 1.81 kg of feed/d. Upon entering the farrowing house at approximately 110 d of gestation, all animals, regardless of previous treatment, were fed the same lactation diet (15% protein corn-soybean meal diet) until the pigs were weaned (28 d). After completing three parities, 88 of a possible 90 litters were farrowed by each dietary group. Total number of live pigs at parturition and 21 d for three parities were: (SBM) 887, 732 and (RSB) 924, 765, respectively. Average pig birth and 21-d weights for each dietary group were (SBM) 1.52, 5.42 and (RSB) 1.59, 5.41 kg, respectively. Pigs from dams fed RSB had higher average pig birth weights (P less than .05), but weaning weights were not affected. There were no significant differences in maternal weight changes during gestation. Milk samples were collected within 6 h after parturition, 3 and 14 d of lactation. Percentage milk fat for each time period was: (SBM) 5.6, 9.0, 7.0 and (RSB) 6.3, 10.7, 6.5, respectively. Sows fed RSB had a higher milk fat at 3 d (P less than .05) but a lower milk fat at 14 d (P less than .1) than did the sows fed SBM. The study indicated RSB can be effectively utilized in gestation diets fed to swine.

“…In the present study, ADG, ADFI, and G:F were improved in pigs fed with crumble diet. Previous studies have reported that crumble diet could improve both daily gain and feed efficiency of pigs (Hanke et al 1972;Baird 1973;Braude and Rowell 1996). Similar results have been reported by Braude (1967) and Vanschoubroeck et al (1971) in different trials.…”

This study was conducted to determine the effect of crumbled diet on growth performance, market day age, and meat quality of growing-finishing pigs. A total of 120 crossbred pigs [(Landrace × Yorkshire) × Duroc] with an average initial body weight (BW) of 25.89 ± 1.93 kg at 68 days of age were randomly allotted to 2 experimental diets based on initial BW (15 replicate pens per treatment, 4 pigs per pen; 2 barrows and 2 gilts). The trial lasted for 120 days. Dietary treatments included: (1) T1 (mash diet); (2) T2 (crumble diet). During the overall study period pigs fed the T2 (crumble diet) had significantly greater (P < .05) average daily gain (ADG) and gain to feed ratio (G:F). Moreover, the number of pigs reaching market age at day 177 was higher in pigs fed crumble diet than mash diet. No significant differences were observed in back-fat thickness, meat colour, sensory evaluation, cooking loss, drip loss, water holding capacity, and longgissimus muscle area (LMA) between T1 and T2 groups. Our results revealed that the growth performance was significantly enhanced in pigs fed with the crumble diet. The crumble diet reduced market day age and meat quality of growing-finishing pigs.ARTICLE HISTORY

“…It has been previous reported that feeding pelleted diets could significantly increase FCR [ 5 ]. Increased nutrient digestibility and decreased feed wastage might have improved feed utilization in pigs feeding with pelleted diets [ 18 ]. Burnham et al [ 19 ] have emphasized extrusion of soybean can improve rate and efficiency of gain when fed to nursery pigs in the place of soybean meal.…”

BackgroundPhysical and chemical properties of feedstuffs can be changed by feed processing. Moreover, through various mechanisms, feed processing can affect growth performance and feed efficiency of swine, nutrition value of the feed. Weaning-to service-intervals (WSI), subsequent farrowing rates, and total-born litter sizes were determined by feed intake and metabolic state during lactation.MethodsA total of 20 sows (Landrace × Yorkshire) with an average body weight (BW) of 266.1 kg 4 d before farrowing were used to determine the effect of feed processing on the performance of lactating sows and their offspring. The following two dietary treatments were used: 1) Crumble diet (C); and 2) Mash diet (M). Ten replications were used for each treatment. Back fat thickness of sows was measured 6 cm off the midline at the 10th rib using a real-time ultrasound instrument at 4 d before farrowing, 1 d after farrowing, and during weaning. Sow BW were also checked at 4 d before farrowing, 1 d after farrowing, and during weaning. Fecal score of sows were assessed on d 14. Fecal score of piglets were observed on d 7, 15, and 24. Data were analyzed using t-test procedure of SAS (2014) with sow as experimental unit.ResultsNo significant (p > 0.05) difference was observed in the reproduction performance of sows between the two treatments. In addition, there was no significant (p > 0.05) difference in the growth performance of piglets between the two treatments. Fecal score of sows or piglets showed no significant (p > 0.05) difference either.ConclusionsIn conclusion, different feed processing (mash or crumble) did not make any significant difference on the performance of lactation sow or their piglets.
