“…That frequency of feeding had no effect on these variables is in agreement with the results in pigs (Friend and Cunningham 1964) and in sheep and rats (Han 1965 (Sharma et al 1971.). The percent DE and percent ME in this experiment were also similar for the Hampshire X Yorkshire breed also reported earlier (Sharma et al 1972 Hampshire X Yorkshire pigs (Sharma et al 1971(Sharma et al .1972).…”

Les Meal feeding, the consumption of food in a single short daily pcriod (Leveille 1970), as opposed to nibbling, caused an increased elliciency of energy utilization in rats (Cohn 1963;Kekwich and Pawan 1966) (Friend and Cunningham 1964 (Sharma et al 1971). They were allottecl to individual stainless sleel metabolism cages and were initiated to the experiment after 1 wk of acclimatization.…”

and 340 kcal ME/W.'-n" daily; and feeding frequency: two and five times daily)'One metabolism experiment was conducted during the 3rd wk of the 37-day feeding experiment. Subcutaneous adipose tissue slices taken immediately after electrocution of 24 pigs were used to determine the rate of lipogenesis as indicated by the metabolism of glucose-U-'+C. Frequency of feeding had no effect on the digestible energy, ME, and N8,,, value of the diet or the efficiency of utilization of ME for maintenance. However, frequent feeding increased the fasting heat production, metabolizable energy requirement for maintenance, net efficiency of utilization of metabolizable energy for production and the NE, value of the diet. Frequency of feeding did not produce any change in the weights of empty stomach or small intestine. Although the rate of lipogenesis in the adipose tissue was not affected by feeding frequency, lipogenesis was increased by an increase in the level of dietary energy inputs. Feeding frequency did not influence the body composition and energy concentration in the empty body of pigs fed 240 and 340 kcal ME./W' t"r" but frequent feeding incteased percent water and reduced percent fat in pigs fed 140 kcal ME/W''"*" daily. Several of the latter pigs were in negative energy balance.

“…Upon correcting their data for this lower dressing percentage (calculating the protein and fat deposition), these differences in performance were no longer present. Similarly, Friend & Cunningham (1964) did not detect any differences in performance between feeding the same amount of feed daily as one or five meals, when calculating the protein and fat deposition. De showed that pigs which spend a long time eating utilized feed less efficiently, probably due to extra energy losses for activity.…”

Effect of feeding environment on performance, injuries and behaviour in growing-finishing pigs: groupbased studies.Ten batches of pigs (608 pigs) were used in this investigation (live weight interval 20 -120 kg). Four different feeding systems were tested: one dry feeder, four dry feeders, trough feeding or one wet/dry feeder per pen of 16 pigs, respectively. The one dry feeder treatment led to an increase in skin injuries, a more spread feed intake pattern, an increased variation in carcass meat percentage and an increased variation in daily weight gain (DWG) when the pigs were restrictively fed, compared with observations for the pigs in the four dry feeders treatment. The effect of a reduced number of feeding places was most pronounced when the pigs were fed restrictively. Besides the possible negative financial effects for pig producers, these findings indicated that competition for feed impaired the well-being of the pigs. Pigs fed in a trough had a lower DWG and higher feed conversion ratio than did those fed using four dry feeders, probably due to feed spillage and the different feed intake pattern. Giving pigs the possibility of adding water to the feed increased the daily feed intake when feeding ad libitum, resulting in a higher DWG. It also reduced the negative effects of competition on performance, but not the negative effects on skin injuries.
