Abstract Starch gelatinization of pet foods can be impacted by several factors, including moisture, retention time, and ingredients used. Starch gelatinization has been associated with effects on digestibility, but isn’t well studied in non-traditional canine diets. The objective of this research was to examine the impacts of dietary ingredient profile (traditional vs. non-traditional) and assess impacts to total starch content and starch gelatinization. Traditional diets (n = 10) utilizing meat-based ingredients including chicken, chicken byproduct meal, meat and bone meal and plant-based ingredients including rice, barley, oats, and corn were examined in comparison with non-traditional diets (n = 10) utilizing meat-based ingredients including alligator, buffalo, venison, kangaroo, squid, quail, rabbit, rabbit and salmon along with plant-based ingredients including tapioca, peas, chickpeas, lentils, potato, and pumpkin. Representative samples were collected via grab sample technique (5 samples/diet) and were assessed for total starch content as well as percent starch gelatinization. Variation between both diet types were assessed with a nonlinear regression using SAS 9.4. Significance was set at P < 0.05. Distribution of total starch content based on ingredient type (traditional vs non-traditional) reveal that mean total starch content is 15% higher in traditional diets as compared to non-traditional diets (P < 0.0001). Conversely, percent starch gelatinization was found to be 10% higher in non-traditional diets (P < 0.0001). Total starch content and percent gelatinization had a highly significant non-linear relationship (P < 0.0001). These novel data reveal important differences between starch content and gelatinization and could impact manufacturing processes for ingredient types as well as feeding recommendations.

Gelatinization of starch content in pet foods can be impacted by several factors including moisture, retention time, and ingredients used. Starch gelatinization has been associated with digestibility but isn’t well studied using ingredients common in non-traditional canine diets. The objective of this research was to examine the impacts of dietary ingredient profile (traditional vs non-traditional) and assess impacts to total starch content and starch gelatinization. Traditional diets (n = 10) utilizing meat-based ingredients including chicken, chicken by-product meal, meat and bone meal and plant-based ingredients including rice, barley, oats, and corn were examined in comparison with non-traditional diets (n = 10) utilizing meat-based ingredients including alligator, buffalo, venison, kangaroo, squid, quail, rabbit, rabbit and salmon along with plant-based ingredients including tapioca, peas, chickpeas, lentils, potato, and pumpkin. Representative samples were collected via grab sample technique (5 samples/diet) and were assessed for total starch content as well as percent starch gelatinization. Difference between ingredient type was assessed using a Students t-test in SAS 9.4. Significance was set at P < 0.05. Distribution of total starch content based on ingredient type (traditional vs non-traditional) revealed that mean total starch content was higher in traditional diets as compared to non-traditional diets (P <0.0001). Conversely, starch gelatinization was found to be higher in non-traditional diets (P < 0.0001). Total starch content and total gelatinized starch had a strong negative correlation (P < 0.01) in traditional diets, though no correlation was observed in non-traditional diets. This negative correlation indicates a decrease in total gelatinized starch associated with increased total starch content. These novel data reveal important differences between starch content and gelatinization and could impact manufacturing processes for ingredient types as well as feeding recommendations. Unpredicted variation between ingredient formulations could potentially lead to decreased digestibility and absorption and may result in nutrient deficiencies.

Semiquantitative Method

To control the spread of bovine spongiform encephalopathy, several DNA methods have been described for the detection of the species origin of meat and bone meal. Most of these methods are based on the amplification of a mitochondrial DNA segment. We have developed a semiquantitative method based on real-time PCR for detection of ruminant DNA, targeting an 88-bp segment of the ruminant short interspersed nuclear element Bov-A2. This method is specific for ruminants and is able to detect as little as 10 fg of bovine DNA. Autoclaving decreased the amount of detectable DNA, but positive signals were observed in feeding stuff containing 10% bovine material if this had not been rendered in accordance with the regulations, i.e., heated at 134°C for 3 instead of 20 min.

Significant Difference

A four week experiment was conducted to evaluate the effect of isoproteinous (35%) feed prepared named diet 1, 2, 3 and 4 respectively by substituting 0%, 50% , 75% and 100% fish meal with meat and bone meal in view of preparing a cost effective tilapia (Oreochromis niloticus) fry feed. The four experimental diets (diet 1 to 4) each were randomly assigned to twelve hapas with three replications. Tilapia fry (0.011g) were randomly stocked in 100 fry/9ft² hapa and fed five times a day up to their apparent satiation. The results of the study showed that the weight gain, specific growth rate (SGR), the apparent net protein utilization value and survival (%) of the fish were significantly  (P<0.05) higher and better feed utilization with lower FCR value was observed in fish fed on the diet 4 where meat and bone meal was used as sole source of protein base. There was no significant difference between the carcass moisture and lipid of fish fed with different experimental diets. The results of the study indicated that diet 1 containing fish meal (45.15% Fish meal, 27.43% Rice bran and 27.43% Wheat flour) can be replaced by meat and bone meal containing diet 4 (54.06% Meat and bone meal, 22.97% Rice bran and 22.97% Wheat flour) with no adverse effects on growth and survival of O. niloticus. Before recommendation several trials will be necessary in different farms to be  sure of the reproducibility of the result obtained in the present experiment. Cost- benefit analysis reveals that the   meat and bone meal containing diet certainly provides cheaper feed.   DOI: http://dx.doi.org/10.3329/jbau.v10i1.12110   J. Bangladesh Agril.

Dietary Treatments

Dietary supplementation with folic acid has been shown to improve reproductive performance in sows (Lindemann 1993). However most studies have been for one cycle only and few have examined the effect of supplementation over several parities.One hundred and thirty four crossbred sows ranging in parity from 2 to 4 were selected at farrowing and randomly allocated to two dietary treatments of low and high supplemental folic acid (0 and 10 g per tonne, Roche Products Ltd.). Treatments were applied for the following three lactations and post weaning periods, two full pregnancies and to day 30 of the pregnancy following the third lactation. The diet fed contained barley, wheat, soyabean meal and meat and bone meal with nutrient levels of 14.0 MJ DE/kg and 1.02% lysine. Sows were individually penned throughout with restricted feeding in pregnancy (2.2 kg/day increasing to 2.5 kg/day in the final month), and ad libitum in lactation (approx 5.0 kg/day) and post weaning (approx 3.4 kg/day). Blood samples for determination of plasma and red cell folate were taken from 14 sows per treatment on days 4, 50 and 110 of one cycle. These were determined by a microbiological assay (modification of methods of Scott et al 1974 and Wilson and Home 1982).
