The Impact

A study was designed to assess the impact of water-soluble proteins and peptides extracted from meat and bone meal (MBM) on broiler chick performance, following their oral delivery during the early post-hatch period. Proteinaceous material was fractionated by size exclusion filtration into weight ranges of <3 kDa (Fraction 1; 0.5 mg protein/mL), 3–100 kDa (Fraction 2; 0.5 mg protein/mL) and >100 kDa (Fraction 3; 0.8 mg protein/mL), which formed the three protein fraction treatments. A total of 1 mL of each of the respective preparations was delivered orally via gavage over 4 days (0.25 µL each day) to Cobb broiler hatchlings. Three control groups: control–unhandled, control–phosphate-buffered saline and control–handled were also included. Chicks were grown to 30 days of age. Feed intake, chick weight gain and feed conversion ratio were determined from day old through to 29 days of age. On Days 10, 16, 23 and 30, the weight of the breast and the small intestine was determined from 10 birds/treatment. For all parameters measured there was no interaction between experimental week and protein fraction treatment. Chicks receiving Fraction 2 had a statistically significant increase in feed intake and weight gain (P = 0.012) compared with the control–unhandled chicks. Chicks receiving Fraction 2 also demonstrated a numerically higher final bodyweight. Mass spectrometric analysis of all three fractions revealed that they each contained a wide array of proteinacious material. The results of this study suggests the likelihood that protein or protein-derived fragment components within the 3–100 kDa molecular weight range of MBM can generate improvements in broiler chick production, and thus promote the need for further research to identify the specific protein(s) responsible for the observed positive growth effects.

The Impact

The aim of this study was to verify the impact of adding vinasse as an acidifier in sows diet during the lactating period and its effect on litter. A total of 14 agroceres females were used from the first day of lactation until weaning. The vinasse was obtained in a mill near the experimental facility and was stored in sterilized barrels. Animals were distributed in a completely randomized experimental design into two treatments: control liquid diet and liquid diet with the inclusion of vinasse in each feed supply of the day. The diets were supplied four times a day, containing a mixture of ½ L of vinasse and ½ L of water. Feed leftovers were weighted daily. Feed intake was used to evaluate sows’ performance. The piglets were weighted every week after birth until weaning in order to obtain weight gain. Vinasse inclusion showed an increase (p < 0.05) in feed intake of lactating sows, improving diet palatability. Inclusion of acidifier in the diet did not show (p > 0.05) difference in weight gain of piglets. Vinasse consumption by sows did not influence litter performance. The inclusion of vinasse in the diet of lactating sows is beneficial because increases feed consumption.

The Impact

The paper assesses the impact of combustion of biofuels produced based on municipal sewage sludge in stoker-fired boilers on the amount of pollutant emissions and examines the tendency of ash deposition of biofuels formed during the combustion process. The combustion tests were performed in a laboratory system enabling simulation of a combustion process present in stoker-fired boilers. The study was conducted for three types of biofuels; i.e., fuel from sewage sludge and coal slime (PBS fuel), sewage sludge and meat and bone meal (PBM fuel) and fuel based on sewage sludge and sawdust (PBT) with particle size of 35 mm and 15 mm. This paper describes and compares the combustion process of biofuels with different granulation and composition and presents the results of changes in emission values of NOx, SO2, CO, and CO2. The emission results were compared with the corresponding results obtained during combustion of hard coal. The results showed that biofuels with lower particle sizes were ignited faster and the shortest ignition time is achieved for fuel based on sewage sludge and coal slime-PBS fuel. Also, the highest NO and SO2 emissions were obtained for PBS fuel. During the combustion of fuel based on sewage sludge and meat and bone meal (PBM), on the other hand, the highest CO2 emissions were observed for both granulations. Biofuels from sludge show a combustion process that is different compared to the one for hard coal. The problems of ash fouling, slagging, and deposition during biofuels combustion were also identified. The tendency for ash slagging and fouling is observed, especially for fuel from sewage sludge and meat and bone meal (PBM) and fuel based on sewage sludge and sawdust (PBT) ashes which consist of meat and bone meal and sawdust which is typical for biomass combustion.

An investigation on Long Evans male rats fed with different edible fats and oils was conducted in the Department of Physiology, Bangladesh Agricultural University, Mymensingh during a period of 7 weeks (1st April to 19th May, 2005) to determine and to compare the effect of feeds on body weight gain and on weights of some selected organs (heart, liver and kidney) removing the impact of unequal feed intake. A total of 20, six-week old male rats were randomly divided into A, B, C and D groups. Each group consisted of 5 rats. Rats were fed rat pellets purchased from ICDDR,B, Dhaka supplemented with beef fat in group A, fish fat in group B and soybean oil in group C while group D was considered as control and fed only with rat pellets. The concentration of fats and oils were 7% of normal diet and fed for 7 weeks. The highest weekly mean body weight gain (19.90g) adjusted for unequal feed intake was achieved by the rats of beef fat supplemented group A, followed by the rats of soybean oil supplemented group C (19.76g) and fish fat supplemented group B (15.67g). But none of the adjusted means of weekly body weight gain differed significantly (p > 0.05) from the control. Insignificant increases in heart weight were recorded in all treated rats and the maximum weight was in fish oil treated ones. Not much differences were recorded in the kidney weights rather beef oil treated rats' kidney had the lowest mean weight. A significantly (p < 0.01) higher liver weight was recorded in group B & C compared to control (group D), though the differences between A & D were insignificant. It could be concluded that fats and oils are harmful for the rat's body especially on liver and heart.

The effect of replacing an antibiotic growth promoter in the diet with a probiotic on growth performance, carcass characteristics and nutrient retention was studied in broilers (Vencobb 430) fed with and without meat cum bone meal (MBM). This experiment which lasted for 42 days consisted of six dietary treatments viz., basal diet (BD), basal diet with MBM (MBM), basal diet with antibiotic (AB), basal diet with probiotic (PB), basal diet with MBM and antibiotic (MBM+AB) and basal diet with MBM and probiotic (MBM+PB). Three-hundred, day-old chicks were randomly allotted in the beginning to these six groups. Body weight gain, feed intake and feed conversion ratio were significantly (P less than 0.05) affected at 4th week of age. Overall, highest body weight gain was recorded in birds fed with AB and PB. Inclusion of probiotic in MBM also showed improved body weight gain when compared to MBM group. Highest feed intake and feed conversion ratio was recorded with AB and PB groups. Birds supplemented with MBM+PB showed improved feed intake and feed efficiency when compared to MBM+AB and MBM diet supplemented groups. Higher dry matter, crude protein, calcium and phosphorus retention (P less than 0.05) was observed in birds supplemented with PB or AB in diet without MBM when compared to their control. In MBM supplemented groups addition of PB or AB improved crude protein retention. Birds supplemented with PB or AB with or without MBM showed a significant (P less than 0.05) increase in thigh yield and a non significant reduction in fat yield when compared to their control groups.

The Impact

This study was carried out to evaluate the impact of raw and cooked wild cocoyam (Caladium bicolor) on the performance of broiler chicks. Wild cocoyam corms were divided into two batches. One batch was ground raw and the other batch was cooked before grinding. Wild cocoyam meals so prepared were used to formulate 5 broiler starter diets at dietary inclusion levels of 0, 10 and 20% raw and cooked wild cocoyam respectively. 180 7-day-old Anak broiler chicks were randomly allotted to the five treatment diets in a Completely Randomized Design (CRD) and each group was further subdivided into three replicates of 12 birds. Measurements recorded included weight gain, feed intake, feed conversion and protein efficiency ratios and economics of production. Results shows significant (p<0.05) improvement in feed intake, weight gain, feed conversion ratio and PER of birds fed cooked wild cocoyam meals. Marked (p<0.05) reduction was however, obtained in feed intake and feed conversion ratio of birds fed raw wild cocoyam diets. There was no significant (p>0.05) difference between birds fed maize-based (control) and cooked wild cocoyam diets. Results of this experiment indicated that cooking improved the nutritive value of wild cocoyam since birds fed cooked wild cocoyam diets produced best results than those fed raw wild cocoyam meal and that starter broilers could tolerate up to 20% dietary inclusion level of cooked wild cocoyam without any deleterious effect. Economics of production showed that cooked wild cocoyam diets were more profitable as regards the cost of feed per kg weight gain (N) and thus cost savings (%).

The Impact

During utilization of animal waste meat and bone meal (MBM) is received, realization and use of which has been stopped due to risk for the transmission of the bovine spongiform encephalopathy infection. The MBM must be safely stored or treated. Most often meat and bone meal undergoes thermal treatment. During combustion large quantities of residues (ashes) are received, the recycled use of which has been given a lot of attention lately. In this work it was investigated the impact of the additive of the bottom ash (BA) formed during combustion of the MBM on the properties of forming mass and ceramic body of hydromica clay, and also it was evaluated a possibility to use the MBM BA in manufacturing of building ceramics. After replacing the sand in porous ceramics by this additive the plasticity of the forming mass, drying and firing shrinkage as well as density of ceramic body changed insignificantly whereas the compressive strength increased by 8 % - 22 %. So the MBM BA can be utilized in production of porous ceramics.http://dx.doi.org/10.5755/j01.ms.17.1.256

A feeding trial was conducted for six weeks to assess the optimum replacement value of processed rock phosphate (PRP) for bone meal and as a source of inorganic phosphorus in maize-cotton seed meal based diets. A total of 144 day old Snack 80 strain broiler chicks were used. Triplicate groups of 12 birds were randomly placed on 4 diets containing 0. 1.8, 2.8 and 5.64% PRP which contributed 0,0.16, 0.25 and 0.5% inorganic phosphorus in the diets respectively, Results showed PRP levels in dicts had no significant (P>0.05) effect on weight gain, growth rate and feed intake at 0 - 4 weeks. When 2.8% PRP replaced 2% of bone meal, feed efficiency was not significantly different from those birds fed 3% bone meal in control diet. Inclusion of 5.64% PRP significantly (P<0.01) depressed feed efficiency more than other treatment groups during the period. Addition of 5.64% PRP supported higher growth rate than other treatment groups during 5 - 6 weeks, but this was not significantly different from birds fed on control and 2.8% PRP diets. Feed efficiency was significantly (P>0.01) lowest in the group fed on 1.8% PRP diet. Weight gain, growth rate and feed intake were not significantly (P<0.01) affected by treatments during 0-6 weeks. It was concluded that 5.6+% PRP which supplied 0.5% inorganic phosphorus supported optimum performance in broiler birds replacing 100% bone meal in a liu diet and caused growth that was equinob-ut to the group fed on 3% bone meal mentraal diet.

The Impact

Water soluble polysaccharides (WSP) were isolated from Lentinus edodes fruiting bodies. The mushrooms were previously subjected to various processing techniques which included blanching, boiling, and fermenting with lactic acid bacteria. Therefore, the impact of processing on the content and biological activities of WSP was established. Non-processed fruiting bodies contained 10.70 ± 0.09 mg/g fw. Boiling caused ~12% decrease in the amount of WSP, while blanched and fermented mushrooms showed ~6% decline. Fourier transform infrared spectroscopy analysis (FTIR) confirmed the presence of β-glycosidic links, whereas due to size exclusion chromatography 216 kDa and 11 kDa molecules were detected. WSP exhibited antioxidant potential in FRAP (ferric ion reducing antioxidant power) and ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) assays. Cytotoxic properties were determined on MCF-7 and T47D human breast cell lines using MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) test. Both biological activities decreased as the result of boiling and fermenting.

SummaryThe nutritive value of diets predominantly of dried cassava (Manihot esculenta Crantz.) tubers supplemented with protein concentrates, and roughage were measured in three experiments using steers.In Expt 1 the digestibility of diets of dried, chipped cassava tubers and tops (80:20) or rolled sorghum grain and cotton seed hulls (80:20), supplemented with 4 or 8% groundnut meal and urea, was determined. The apparent digestibility coefficients of organic matter (OM) of the cassava diets with 4 or 8 % groundnut meal (0·77 and 0·80, respectively) were significantly (P < 0·01) higher than grain diets with 4 or 8% groundnut meal (both 0·74). The digestibility of starch in the cassava diets was significantly (P < 0·01) higher than in the grain diets (1·00, 0·99, 0·94 and 0·93, respectively). There were no significant differences in the digestibility of the N component (0·62 and 0·61 v. 0·58 and 0·59, respectively). The N retained (g/day) was lower (P > 0·05) with cassava (7·8 and 6·8 v. 11·1 and 10·5, respectively) and was utilized (g/100 g apparently absorbed N) less efficiently (P > 0·05) (18 and IS v.28 and 27, respectively).The high apparent digestibility of the cassava diet suggests that cassava could replace cereal grain in intensive finishing diets. The N retention data suggest that groundnut meal is no better than urea as a N source.In Expt 2, 15 steers with a mean initial weight of 173 kg were individually fed pelleted diets of sorghum grain, cassava plus urea or cassava plus meat and bone meal (90 concentrate: 10 roughage). The cattle fed the grain diet ate significantly (P < 0·01) more OM (4·3 v. 3·4 kg/day), grew faster (P < 0·01) (1·21 v. 0·85 kg/day) and slightly more efficiently (P > 0·05) (3·6 v. 3·8 kg/kg) than cattle fed cassava with urea. Cattle fed cassava with meat and bone meal were intermediate between the two treatments for intake and daily gain (3·7 and 1·06 kg/day, respectively) but had the best feed conversion (3·5 kg/kg). The acetic/propionic acid ratio was similar on all three diets (1·2, 1·6 and 1·4:1, respectively), but the ratio of propionic/butyric was significantly (P < 0·01) different (5·8, 2·7 and 2·7:1, respectively).In Expt 3, 15 other steers with mean initial weight of 195 kg were individually fed pelleted cassava diets with 0, 5 or 10% fishmeal (82 cassava: 18 roughage). The intake of OM (4·2, 4·5 and 4·7 kg/day, respectively), daily live-weight gain (0·98, 1·27 and 1·32 kg/day, respectively) and feed conversion (4·3, 3·7 and 3·7 kg/kg, respectively) were all better in cattle fed cassava with fishmeal. The proportions of volatile fatty acids in the rumen fluid were similar to that recorded in cassava fed cattle in the earlier trial.It is concluded that cattle fed high energy diets based on dried cassava tubers can perform well. Although feed intake and daily gain of cattle fed cassava may be lower than for cattle fed grain diets, the conversion of food to live-weight gain should be similar or better.
