“…Lucas and Lodge (1961) (Zimmerman and Khajarern 1973). The consensus is that complex starter diets promote greater feed intakes and weight gains than do simple diets (Meade et al 1969;Bayley and Carlson 1970;Zimmerman 1972 (Zimmerman and Khajarern 1913). It is possible, however, that the use of complex starter diets could significantly reduce the check in growth associated with weaning (Smith and Lucas 1956;Meade et al 1965;Bayley and Carlson 1970 …”

Two experiments were conducted to study the performance of 3-and 5-wk-weaned pigs fed creep or starter diets of differing complexity. In experiment l, 36 litters, adjusted to seven or eight pigs per litter, were randomly allotted to four dietary treatments: no creep feed or ad libitum access to a feed of a simple, semi-complex or complex fbrmulation during the pre-weaning period from l0 days of age until weaning at 3 wk of age. After wcaning, pigs were paired by weight, within litters and treatments and each pair randomly allotted to one of the three diets. The post-weaning feeding period was from 3 to 7 wk of age. In experiment 2 the same creep and starter treatments as were used in experiment I were fed to zl8 litters from 2 to 5 wk of age. After weaning, litter sizes were adjusted to seven or eight pigs and four litters from each pre-weaning treatment were allotted to each of the diets from 5 to 8 wk ofage. In both experiments, creep feed intake was low for all three diets and though more of the complex diet was caten in both experiments there were no significant differences in mean piglet weaning weight. In the post-weaning period, increase in diet complexity led to a corresponding increase in feed intake and weight gain. Only in the first experiment were the difTerences in post-weaning weight gain significant (P < 0.001 Lysine (

“…In a series of triah (10,11) it was found that the inclusion of dried skimmilk or fishmeal in corn-soybean meal diets did not consistently improve liveweight $owth. Also, corn-soybean meal diets which contained between 18 and 2IVo protein appeared adequate as measured by rate of gain (9, (Table 2) and fed until a mean pen liveweight of 50 kg was attained.…”

“…Most of the work in this area has been done on growing pigs and with all vegetable diets. Bowland and Asplund (1960) reported that lysine additions to a basal wheat ration containing 10% protein, when the ration was fed to baby pigs, increased gains, but that methionine and tryptophan additions to the Long et al (1962) and Meade et al (1965) were both unable to show a growth response when lysine was added to a 167,-corn-soybean meal starting diet. Long et al (1962) found added lysine depressed growth of pigs from 3 to 5 weeks of age, but they added lysine at what would be considered excessive levels.…”

Experiments were designed to study fat, lysine, and methionine additions to rations containing three levels of crude protein for weanling pigs from 3 to 9 weeks of age.The experiments were 3 x 5 x 2 x 2 factor¬ ials in which the factors were fat level, protein treatment, breed group, and sex. The levels of supplemental fat were 0, 4, and 8 per cent. The five protein treatments were based on rations containing 12, 16, or 20% protein and 12 or 16% protein supplemented with lysine and methionine so that the level of these amino acids was calculated to be the same as in the 20%,-protein ration. The two breed groups were Lacombe x Yorkshireand Hampshire x Lacombe-Yorkshire .Increasing protein from 12 to 16% resulted in doubling the rate of gain (from 0.11 to 0.22 kg/day) while increasing protein from 16 to 20%, resulted in a smaller but significant increase (from 0.22 to 0.28 kg/day).Increasing the lysine and methionine in the 12 and 16%, rations resulted in a 27 and 36% increase in rate of gain, respectively. Average daily feed intake was increased when the protein level was increased from 12 to 16%,, but the increase in feed consumption was not significant when protein was raised from 16 to 20 per cent. Supplemental lysine and methionine added to the 12 and 16%,-protein rations resulted in a 13%, increase in daily feed intake. Efficiency of feed utilization was improved (P <0.05) as protein was increased from 12 to 16%, (2.97 and 2.14 kg feed/kg gain, respectively) and supplementing these rations with lysine and methionine resulted in a further improvement of 15 and 17%, in the efficiency of feed utilization.Apparent digestible energy for 6-week-old pigs was not significantly influenced by any of the treatment factors. Apparent nitrogen digestibility and nitrogen retention were significantly (P
