Diets containing clean wheat, deoxynivalenol-contaminated wheat and Fusarium-inoculated corn were fed to 23-kg boars and gilts. Twelve Yorkshire pigs were fed the control diet (CW) and 18 each the contaminated-wheat (VW) and the inoculated corn (IC) diets (3.7 and 4.2 mg deoxynivalenol kg−1 respectively) for a 7-wk period, at which time each pig was necropsied. The diets caused a 23–29% reduction in feed consumption with considerable variation among pigs within diets. The VW pigs gained 30% less and the IC pigs 72% less weight than the controls. Differences in performance between boars and gilts were not significant (P > 0.05). Weights of the major body organs at necropsy followed the pattern set by body weights, i.e. CW > VW > IC (except the stomach and uterus), but this relationship did not remain when organ weights were expressed relative to body weight. Dietary differences (P < 0.01) were shown for the fundic region necropsy scores in which the IC diet caused less fundic mucosal inflammation than either of the other two diets, and in the esophageal region where the VW and IC diets seemed to have maintained the integrity of the mucosa better than the control diet. Histological examination of testis (seminiferous epithelium) and ovary (follicle) tissue revealed no significant differences in sexual development attributable to diet. The marked effect of the IC diet on feed intake and weight gain suggests the presence of another metabolite which adversely affected weight gains.

Six hundred and seventy-two 1-day-old male broiler chicks of two strains were used to assess the effects of diet and color of diet on feed consumption. Isocaloric isonitrogenous diets that contained soybean meal (control), rapeseed meal, or ground rapeseed were fed in either colored or noncolored form. During the starter period the birds were given a choice of two diets in various combinations whereas during the grower period no choice was available. In the starter period there were no significant effects of color or diet combinations on total feed consumption. Coloring one diet of a pair, however, tended to increase the difference in consumption between the two by reducing the intake of the colored diet. The one exception to this was the diet pair containing ground rapeseed, which was not affected when one diet was colored. The control diet was preferred, followed by the diets containing rapeseed meal and ground rapeseed, respectively, when a choice was available. When no choice of diet was available in the grower period the only significant effect of color was to increase consumption of the ground rapeseed-containing diet. Weight gain in both periods was highest on the control diet followed by the diets containing rapeseed meal and ground rapeseed, respectively.

ABSTRACT. The aim of this experiment is to investigate a possibility to include tofu by-product in broiler diet without causing adverse performances. This study was conducted in poulty production Lab. Faculty of Agriculture, Syiah Kuala University, Banda Aceh. The study performed 80 unsex day old chick, strain CP 707, Charoen Pokphan product, for which the chikens were divided into for diet treatment. The study was desingned into Completely Randomized Design (CRD) containing for different diet treatment. ei. R1 (Control diet with 0% of tofu by product. R2 (the diet containing 2.5% of tofu by-product), R3 (the diet containing 5% of tofu by-product, and R4 (the diet containing 7.5% of tofu by-product). Each treatment consisted of five chiks. Investigated variables included  final body weight, body weght gain, feed consumption, feed conversion, and income over feed and chick coast (IOFCC). The data were analyzed by an analysis of variance and as a significant effect was detected, the analysis  was continued by Duncan Multiple Range Test based on Steel and Torrie (1991). Result of this study showed that the inclusion of up to 5% of tofu by-product in the diet were not significantly defress body weight, body weight gain, feed consumpsion, and feed conversion compared to the control. However, the inclusion of 7.5% of tofu by-product significantly defress body weght, body weight gain feed consumpsion. The was no significant effect on feed conversion as tofu by-product was included 7.5% in the diet. The inclusion of tofu by-product could minmize diet cost and increase.

Effect Of Feeding

Background: Fungal laccases have widespread application in a number of biotechnological processes including the biodegradation of lignin. Their low yield in the native state limits their practical use in the deconstruction of lignocellulosic biomass for feeding ruminants. Enzymes in bulk quantities are required to treat biomass which has got greater product consistency and less lot to lot variations. The present study was an attempt to evaluate the effect of feeding finger millet straw treated with exogenous laccases in heifers.Methods: The effect of feeding exogenous laccases obtained from immobilized Schizophyllum commune (MTCC 11893) on body weight gain, dry matter intake and nutrient digestibility in heifers was evaluated in three groups of heifers (4-each) with body weights ranging between 275 ± 47.12 to 276.75 ± 64.48kg. The control group received ad lib. finger millet straw treated with only production media (GI). Test group 1 (GII) received ad lib. straw treated with laccase rich media in a 3:5 (w/v) ratio, while test group 2 (GIII) received ad lib. straw treated in a 4:5 (w/v) ratio. Result: After 14- days of feeding, gain in body weights for GI, GII and GIII were 277.9 ± 68.47; 277.50 ± 46.43 and 278.85 ± 37.22 respectively with an overall increase of 1.15, 4.25 and 3.60 kgs. No significant variation (P greater than 0.05) was observed with regard to DMD (%) between the groups which was 46 ± 5.8 for the control animals and 41±13.0 and 41± 3.4 in G2 and G3 groups. Though significant variations were observed digestibility studies proved inconclusive. Though preliminary results indicate that applying lignin degrading enzymes as feed supplements could enhance digestibility of crop residues in ruminants.

Two trials with finishing lambs were conducted to study the effect of substituting wheat bran for either dehydrated alfalfa pellets or corn. In trial 1, the basal ration fed to lambs was compared by replacing dehydrated alfalfa (12.5%) with wheat bran. Growth responses to wheat bran or dehydrated alfalfa were not different (P>0.74). In trial 2, thirty-two lambs were blocked by weight and randomly assigned to four treatments consisting of the basal ration plus three different levels of wheat bran (22%, 46% and 68%) substituted for corn. The results indicated that animals on the control diet (without wheat bran) performed better (α = 0.5) than the three wheat bran diets, where the two lowest level of wheat bran diet either maintained or gained weight. Animals on the highest level of wheat bran lost weight. Gain response to the corn diet was higher (P<0.25 and P<0.003) than 22% and 46% wheat bran supplemented diets. Results also indicated that diet- A (control) and diet-C (46% wheat bran) had similar DM digestibilities, where as the diet-B (22% wheat bran) gave higher digestibilities for DM, ADF and NDF. ADF digestibility was very low in control diet (A) as compared to diet-B (22% wheat bran) and diet-C (46% wheat bran) because the control diet contained little fiber. Higher protein digestibility was observed in diet-A. Although, diet-B performed better than diet-C, Performance of diet-B was not parallel to that of diet-A and difference between diet-B and diet-C was not statistically significant (P>0.05).

The use of trial specimens of probiotics based on strains of Bacillus subtilis, Bacillus licheniformis and their consortium was experimentally proved to be effective for quail feeding during their growth. The dynamics of live weight gain of quails was monitored. The experiment lasted for 60 days and was carried out in compliance with the standard methods. Quails that were studied were of the Japanese breed formed in four groups of 80 heads in each: one control group and three experimental ones at the age of one day. Quails were kept in a battery cage with all the required environment conditions met. All the groups were fed on the main (control) diet, developed taking into account the age and physiological characteristics of quails. However, birds of experimental groups 1-3 were additionally fed on probiotics based on strains Bacillus subtilis, Bacillus licheniformis and their consortium in the amount of 150 g/t of feed, respectively. The effect of new strains of probiotics and their consortium was tested during the study by the following parameters: the survival rate of birds, intensity of chicken growth, meat productivity and hematological indicators. The optimum variant of probiotics introduction into the diet of quails during their growth period was determined. The recommendations for the preparation of compound feeds with the use of probiotic supplements were developed. The chemical composition of quail feed and meat was studied in the biological laboratory by conventional methods of zootechnical analysis. The introduction of the consortium of strains Bacillus subtilis and Bacillus licheniformis in the amount of 150 g/t led to an increase in the survival rate of quails by 4.0%. The average daily live weight gain increased by 2.57%, feed consumption per one unit of produce decreased by 6.48%. When feeding quails on the consortium of probiotic strains Bacillus subtilis and Bacillus licheniformis in this rate, the mass of the eviscerated bird carcass increased by 3.61%, the protein content in the meat and its biological value increased by 1.06 and 11.11%, respectively. The hematological characteristics of the chickens remained within the physiological norm.

Effect Of Feeding

An experiment was conducted to evaluate the comparative effect of feeding sundried sweet potato and its whole meal to weaner rabbits. The proximate analysis conducted revealed that sundried sweet potato meal and whole sundried sweet potato meal samples were rather low in protein contents as compared to maize. Twenty seven Weaner rabbits averaging 0.35kg were randomly allotted to 3 treatment groups in a completely randomized design. Each treatment group was replicated 3 times. Sundried Sweet potato meal and its whole meal replaced maize at 20% inclusion level. Treatments 1, 2, and 3 contained the control, sundried sweet potato meal (SSPM) and whole sundried sweet potato meal (WSSPM) respectively at 20% levels of inclusion. The weaner rabbits were fed ad-libitum throughout the experimental period. Significant differences (p<0.05) were observed for growth performance of the rabbits in average daily weight gain, average daily feed intake and feed conversion ratio in the weaner rabbits using sundried sweet potato and its whole meal. The values of mean daily weight gain ranged from 16.33g in treatment 2 (SSPM) to 18.47g in treatment 1 (control). Treatment 3 (WSSPM) gave a higher value that is comparable (p>0.05) to that of the control diet but better (p<0.05) than that of treatment 3 (SSPM). The values of average daily feed intake also ranged from 43g in treatment 2 (SSPM) to 50g in treatment 1 (control). WSSPM was consumed more than (p<0.05) than the SSPM which however influenced the cost of total feed consumed. Moreover, the values of feed conversion ratio (FCR) ranged from 2.54 in treatment 3 (WSSPM) to 2.70 in treatment 1 (control). Significant differences (p<0.05) were also observed in bio-economics of production of weaner rabbits using the test diets. The cost per kg feed, cost of total feed consumed per rabbit, cost per kg weight gain and revenue of the rabbits fed the test diets were significantly lower than the control diet however, the cost per kg weight gain was lower (p<0.05) for treatment 3 (WSSPM). For gross margin, WSSPM value was significantly higher (p<0.05) than SSPM value and the control diet. It was concluded that whole sundried sweet potato meal can be a good feed ingredient in rabbit diet.
