“…DFI was similar between D UR and 1 : 3 UR groups. Liquid feeding did improve ADG and LTGR, agreeing with previous results demonstrating an increase in ADG on liquid feeding (Chae et al, 1997). Both the FCR and ADG observed in the current study are comparable with the results published by Stotfold (2005) for finishing pigs reared on an unrestricted diet.…”

“…This further indicates that one of the main advantages of liquid feeding may be the ability to overcome appetite limitations and to access the genetic potential of the pig to lay down muscle. Several studies have reported no differences in the killing-out percentage (Forbes and Walker, 1968;Kornegay and Vander Noot, 1968;Chae et al, 1997) and a similar scenario was observed between our UR groups. In contrast, the killing-out percentage was consistently lower in the pigs offered a restricted ration on the three liquid diets compared with D and is in accordance with observations by others (Patterson, 1989a and1989b).…”

The study examined the growth performance of pigs offered liquid feed or dry feed on either a restricted or an ad libitum basis, and whether their growth performance was further influenced by the water-to-feed ratio. The study was split into two parts to enable unrestricted (trial 1; n 5 64) and restricted (trial 2; n 5 48) feeding to be compared. Male pigs were randomly allocated to six dietary treatment groups. A standard dry pellets diet (D) was offered either as: (i) unrestricted ration (UR); (ii) restricted ration (R); or D soaked in water at a feed-to-water ratio of (iii) 1 : 1.5 restricted (1 : 1.5 R); (iv) 1 : 3 unrestricted (1 : 3 UR); (v) 1 : 3 restricted (1 : 3 R); or (vi) 1 : 3 restricted with the addition of lactic acid to adjust the feed to pH 4 (1 : 3(4) R). Liquid feeding improved (P , 0.05) average daily live-weight gain (ADG) and lean tissue growth rate (LTGR) in the 1 : 3 UR compared with DUR but did not alter feed conversion ratio (FCR). Within the R groups, ADG were greater in all of the 1 : 3 diets, whereas feed intake, and hence FCR, was lower (P , 0.001) in these groups when offered the R ration. In conclusion, liquid feeding has a beneficial influence on the performance of modern porcine genotypes during the growth/finishing phase and this is further modulated by the water-to-feed ratio.

“…Indeed, the majority of research reports are in line with the results of the current study which indicated that feed form does not affect carcass quality. In agreement with Chae et al (1997) stomach integrity (as assessed by keratinization and ulceration) was not affected by feed form (meal or pellets) which is a reassuring finding from a pig welfare perspective.…”

“…The reason for the increase in carcass fat IV is not entirely understood, but 1 hypothesis is that the pelleting process caused increased exogenous fat digestibility and, in turn, resulted in an increase in the amount of dietary oil that is deposited as carcass fat. Chae et al (1997) reported that pelleting diets increased fat digestibility in finishing pigs. Thus, Exp.…”

Two experiments were conducted to determine the effects of pelleting, diet type (fat and fiber level), and withdrawal of dietary fiber and fat before marketing on growth performance, carcass yield, and carcass fat iodine value (IV) of finishing pigs. Each experiment used 288 pigs (initially 49.6 and 48.5 kg BW, respectively) with 6 dietary treatments arranged as 2 × 3 factorials. In Exp. 1, main effects were diet form (meal vs. pellet) and diet regimen. Diet regimens were 1) a low-fiber, low-fat (corn-soybean meal) diet from d 0 to 81, 2) a high-fiber, high-fat (30% dried distillers grains with solubles [DDGS] and 19% wheat middlings [midds]) diet from d 0 to 64 followed by the low-fiber, low-fat diet from d 64 to 81 (fiber and fat withdrawal), and 3) the high-fiber, high-fat diet fed from d 0 to 81.
