“…As for liver weight of the animals, no differences were observed in the organ's weight in response to diets with different digestibilities (KABIR et al, 1998;KIM et al, 2003), while others (ZHOU & KAPLAN, 1997) observed that liver weight was significantly lower in the low digestibility diets, thought no effect of the amylose:amylopectin ratio was observed. In the present study, liver weight also did not correlate with the amylose:amylopectin ratio in rice grains, since the treatments with low (MOCHI) and high (IRGA 417) amylose content presented higher organ's weights.…”

“…However, ZHOU & KAPLAN (1997), evaluating the digestibility of two starch sources, potato with 70-75% amylopectin and maize with 70% amylose, in an experiment with rats during four weeks, also observed significantly greater feed intake with the high amylopectin diet, although no effect was seen on body weight gain. Usually rice grains with low amylose content are more palatable (RAMIREZ, 1991), which can explain the higher feed intake that, associated with the higher digestibility of amylopectin, influenced the body weight gain of the animals.…”

“…The digestion of starch depends on its amylose-amylopectin ratio and their molecular weight (Granfeldt et al, 1994; Englyst and Hudson, 1996). Amylose has more hydrogen bonds and undergoes more rapid retrogradation than does amylopectin (Zhou and Kaplan, 1997), while the amylopectin, having a branched chain, allows a greater access to digestive enzymes. For this reason, amylose is more resistant to hydrolytic enzymes compared with amylopectin (Kabir et al, 1998; Weurding et al, 2001), which may be partly attributed to the presence or development of resistance starch (Behall and Hallfrisch, 2002).…”

“…The positive effects on growth in response to dietary amylose were observed in pigs (Cohen and Tanksley, 1973), poultry (Pirgozliev at al., 2000; Gutierrez Del Alamo et al, 2009) and goats (Kyuma and Ishida, 1989), but the negative effects were observed in rats (Aziz et al, 2009; Denardin et al, 2012), pigs (Perez and Aumaitre, 1979; Camp et al, 2003), and poultry (Ertl and Dale, 1997; Bergh et al, 1999; Pirgozliev et al, 2002; Collins et al, 2003; Pirgozliev at al., 2010). No effect of starch type on growth was also observed in rats (Mongeau et al, 1995; Zhou and Kaplan, 1997; Kabir et al, 1998) and pigs (Shelton et al, 2004). In fish, Rawles and Lochmann (2003) first investigated the starch utilization related to starch type and observed an enhanced growth of sunshine bass ( Morone chrysops ♀ × M. saxatilis ♂ ) when fed with a diet at the higher ratio of amylose-amylopectin starch.…”

A feeding trial was conducted in tilapia to determine the growth performance, nutrient digestibility, digestive enzymes, and postprandial blood metabolites in response to different dietary amylose-amylopectin ratios. Five isonitrogenous and isolipidic diets containing an equal starch level with different amylose-amylopectin ratios of 0.11 (diet 1), 0.24 (diet 2), 0.47 (diet 3), 0.76 (diet 4) and 0.98 (diet 5) were formulated using high-amylose corn starch (as the amylose source) and waxy rice (as the amylopectin source). Each diet was hand-fed to six tanks of 15 fish each, three times a day over a 6-wk period. After the growth trial, a postprandial blood metabolic test was carried out. Fish fed diet 2 exhibited the highest percent weight gain and feed efficiency and protein efficiency ratio, whereas fish fed with diet 5 showed the lowest growth and feed utilization among treatments. The digestibility for starch in fish fed diet 1 and 2 was higher than those in fish fed with other diets (p<0.05). The highest activities for protease, lipase and amylase were found in fish fed the diet 2, diet 1, and diet 1 respectively among dietary treatments, while the lowest values for these indexes were observed in fish fed the diet 3, diet 5 and diet 4, respectively. The liver glycogen concentrations in fish fed diets 4 and 5 were found higher than in fish fed other diets (p<0.05). The feeding rate, hepatosomatic index, condition factor, and plasma parmeters (glucose, triglyceride, total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol) did not differ across treatments. In terms of postprandial blood responses, peak blood glucose and triglycerides were lower after 3 or 6 h in the fish fed with diets 3–5 than in the fish fed diet 1, but delayed peak blood total amino acid time was observed in fish fed with the diets 1 or 2. The lowest peak values for each of the three blood metabolites were observed in fish fed diet 5. The results indicate that high-dietary amylose-amylopectin ratio could compromise growth, but help in reducing the blood glucose stress on fish caused by postprandial starch load.

“…Segundo Rooney & Pflugfelder (1986) e Kabir et al (1998), a digestibilidade do amido é, em geral, inversamente proporcional ao seu conteúdo de amilose, mas, Zhou & Kaplan (1997) observaram em ratos que o amido de batata (70-75% de amilopectina) teve digestibilidade inferior ao amido do milho (70% de amilose).…”

RESUMO -Os experimentos foram conduzidos para avaliar a digestibilidade ileal (CDILEAL) e total (CDTOTAL) do amido e a atividade das enzimas amilase (ATAM) e maltase (ATMAL) em coelhos de 35 e 45 dias alimentados com amido proveniente do milho ou da raspa de mandioca. Em cada ensaio foram utilizados 20 coelhos da raça Nova Zelândia Branco, sendo dez machos e dez fêmeas, alojados individualmente em gaiolas de arame e distribuídos em um delineamento inteiramente casualizado. Ao final do período experimental, os animais foram abatidos para retirada de uma amostra do conteúdo digestivo de uma porção do jejuno e do íleo. Os CDILEAL e CDTOTAL do amido da raspa de mandioca (59,25±1,38% e 99,89±0,04%, respectivamente) foram superiores ao do milho (54,21±1,51% e 99,21±0,05%, respectivamente). O CDTOTAL dos animais com 45 dias de idade foi superior ao dos com 35 dias (99,75±0,04% vs 99,35±0,05%). A ATAM, no conteúdo do jejuno e do íleo, foi maior nos animais com 45 dias (0,952±0,118 mmol de glicose/mg/min e 0,647±0,093 mmol de glicose/ mg/min, respectivamente) do que nos de 35 (0,469±0,111 mmol de glicose/mg/min e 0,375±0,088 mmol de glicose/mg/min, respectivamente). A ATMAL foi maior nos animais alimentados com raspa de mandioca do que nos que receberam milho (0,061±0,007 mmol de glicose/mg/ min vs 0,032±0,007 mmol de glicose/mg/min). Conclui-se que o amido da raspa de mandioca é mais digestível que o do milho, e o sistema enzimático dos coelhos com 35 dias de idade ainda não está suficientemente desenvolvido para que ocorra otimização da digestão do amido.Palavras-chave: amilase, maltase, milho, raspa de mandioca Digestibility of Two Starch Sources and Enzymatic Activity of 35 and 45 DaysOld Rabbits ABSTRACT -The research was carried out to evaluate the ileal (ILEALDC) and total (TOTALDC) digestibility of the starch and the activity of the enzymes amylase (ACAMY) and maltase (ACMAL) in rabbits of 35 and 45 days old, fed with starch from the corn or cassava. In each assay 20 New Zealand White rabbits were used, being ten males and ten females, housed individually in wire cages and distributed in an entirely random arrange. At the end of the experimental period, the animals were killed for retreat a sample of the digestive content of a portion of the jejunum and ileum. ILEALDC and TOTALDC of the starch from cassava (59.25±1.38% and 99.89±0.04%, respectively) were higher than starch from corn (54.21±1.51% and 99.21±0.05%, respectively). TOTALDC of the animals at 45 days old was higher than animals at 35 days old (99.75± 0.04% vs 99.35±0.05%). ACAMY in the jejunum and ileum contends was higher in the animals at 45 days old (0.952±0.118 mmol glucose/mg/min and 0.647±0.093 mmol glucose/mg/min, respectively) than 35 days old (0.469±0.111 mmol glucose/mg/min and 0.375±0.088 mmol glucose/mg/min). ACMAL was higher in animals fed cassava than corn (0.061±0.007 mmol glucose/mg/min vs 0.032±0.007 mmol glucose/mg/min). It can be concluded the starch from cassava is more digestible than starch from corn, and the enzymatic system of th...
