RESUMO -Dois experimentos foram conduzidos para avaliar a inclusão de enzimas exógenas em dietas com diferentes níveis e fontes de proteína para leitões. No experimento I, 80 leitões dos 21 aos 51 dias de idade, desmamados aos 14 dias de idade, foram distribuídos em blocos casualizados, em esquema fatorial 2x2x2 (dois níveis de proteína; com ou sem farinha de carne e ossos; com ou sem enzima), com cinco repetições e dois leitões/baia, e alimentados com dietas à base de milho (M), farelo de soja (FS) e soro de leite em pó (SLP). No experimento II, 40 leitões dos 28 aos 45 dias de idade, desmamados aos 21 dias de idade, foram distribuídos em blocos casualizados, com quatro tratamentos, cinco repetições e dois animais/baia, e alimentados com uma dieta controle à base de M, FS e SLP, com 18% de proteína bruta (PB) e três rações com 0,2; 0,4 e 0,6% do complexo enzimático. No experimento I, não foi observada interação entre nível protéico, com ou sem farinha de carne e ossos e enzima. Houve diminuição do GPD e CMD, com o nível de 18% de PB na ração. Não houve efeito da inclusão de FCO e de 0,2% de enzima na ração. No experimento II, houve efeito linear crescente para GPD e CMD, com o aumento do nível de enzimas. A adição de 0,4% de enzimas exógenas proporcionou o melhor retorno econômico sobre o custo da ração. Concluiu-se que o nível de 21% de PB e a adição de níveis crescentes de enzimas exógenas em rações à base de milho e farelo de soja melhoram o desempenho dos leitões, que não é afetado pela inclusão de 5% de farinha de carne e ossos na ração.Palavras-chave: amilase, celulase, desmame, farinha de carne e ossos, protease, suínos Exogenous Enzymes in Diets with Different Protein Levels and Sources for Pigs in the Nursery PeriodABSTRACT -Two experiments were carried out to evaluate the inclusion of exogenous enzymes in diets with different protein levels and sources for pigs during the nursery period. In the first experiment, 80 pigs from 21 to 51 days of age, weaned at 14 days of age, were assigned to a randomized blocks experimental design, in a 2x2x2 factorial (two protein levels; with or without meat and bone meal; with or without enzyme), with five replicates and two pigs/box, and fed a corn (C), soybean meal (SBM) and dried whey (DW)-based diets. In the second experiment, 40 pigs from 28 to 45 days of age, weaned at 21 days of age, were assigned to a randomized blocks, with four treatments, five replicates and two pigs/box, fed a control diet (C, SBM and DW-based diet with 18% crude protein -CP) and three diets with different levels of enzymatic complex (0.2, 0.4 and 0.6%). In the first experiment, no interaction was observed among protein level, presence or absence of meat and bone meal (MBM) and presence or absence of enzyme. Reduction of ADG and ADFI was observed at the dietary level of 18% CP. No effect of MBM inclusion and 0.2% enzyme in the diet was detected. In the experiment II, it was observed increasing linear effect for ADG and ADFI, as the enzyme level increase. The addition of 0.4% of exogenous e...

“…Pigs fed with the soybean meal diet had a similar growth rate but a lower FI and the best G : F ratio. Early research in pigs indicated that growth performance decreased with increasing levels of meat and bone meal in diets (Peo and Hudman 1962;Evans and Leibholz 1979). We hypothesised that skin-derived protein limits the growth of pigs at the level of 1.5%.…”

A 6-week trial was conducted to investigate the effects of animal skin protein sources from swine and cattle on growth performance, body condition and blood characteristics in growing pigs. A total of 96 pigs (23.50 ± 0.61 kg) were randomly allotted into four dietary treatment groups as follows: (1) basal diet (BD); (2) basal diet with 1.5% hydrolysed render meal (HRM); (3) basal diet with 1.5% swine skin meal (SSM); (4) basal diet with 1.5% cattle hide meal (CHM). There were six replicate pens per treatment with four pigs per pen. The average daily gain (ADG) was improved in response to SSM treatment compared with other treatments (P < 0.05). Pigs fed with HRM, SSM and CHM diets showed increases in average daily feed intake (ADFI) and decreased gain-to-feed (G : F) ratios compared with pigs fed with BD (P < 0.05). There were no differences in dry matter (DM), nitrogen (N), and energy (E) digestibility among treatments. The backfat thickness and lean percentage of pigs was unaffected by the treatments. Similarly, there was no difference in blood characteristics among treatments. In conclusion, the supplementation of SSM in growing pig diets improved the growth rate and Feed Intake (FI), but its usage in swine diets is limited by the poor protein quality.

“…p REVIOUS work at this station (Peo and Hudman, 1962) has shown that meat and bone scraps, when fed at levels from 5 to 10% of the total ration, significantly depress rate of gain of growing-finishing swine. Similar results have been reported by Bloss et al (1953), Terrill et al (1954), Meade and Teter (1957), and Becker and Jensen (1961).…”
