Mustard Meal

Wild mustard seed (Brassica kaber), stinkweed (Thlaspi arvense) and rapeseed (B. napus 'Tower') were fed in diets for growing mice as ground raw seed and as cooked, petroleum ether-extracted meals. In exp. 1, wild mustard seed at 0, 2 or 4% and stinkweed seed at 0, 1 or 2% were substituted for part of the rapeseed in a 3 × 3 factorial design. The control diet contained 20% rapeseed and casein was used to equalize protein levels at 16%. Growth and feed utilization were not affected (P > 0.05). The failure of diets (exp. 1) with 14 – 20% rapeseed and up to 6% weed seeds and containing active myrosinase to depress growth more markedly, is attributed to the relatively low total glucosinolate levels in the diets. In exp. 2, the meals from wild mustard, stinkweed and rapeseed were compared with soybean meal in diets in which each meal provided 3, 6 or 9% protein, with casein used to bring dietary protein to 16%, in a 3 × 4 factorial design. Weed seed meals resulted in lower feed intakes (P < 0.05), with wild mustard meal being the lowest. Increasing levels of wild mustard seed meal and stinkweed seed meal reduced growth rates (P < 0.05), but it is concluded that such meals as contaminants of normally processed commercial rapeseed meal can be fed at relatively high levels in myrosinase-free diets without risk associated with glucosinolates.

Mustard meal was prepared in a pilot plant by expelling and hexane-extracting brown mustard seed (Brassica juncea (L.) Coss.). Steam, ammonia and water were applied during the final stages in the desolventizer. Ammoniated mustard meal (MM) was compared in a swine feeding trial (60 pigs, 25–100 kg) with canola meal (CM; low glucosinolate rapeseed meal), with MM in three combinations with CM and soybean meal (SBM) and with CM + SBM as the protein supplements in six barley:wheat (2:1) diets. Each diet was also fed with and without 0.15% supplementary lysine until pigs weighed 54 kg. Pigs were penned in groups of four and individually fed. Digestibility was determined separately. Ammoniation reduced glucosinolates by over 80% and reduced lysine by 20% but increased crude protein from 44.6 to 51.1%, dry basis. Digestibility values of energy and protein in MM were 72 and 75%, respectively. Digestible energy (10.5% moisture, air-dry basis) was 13.0 MJ/kg and digestible crude protein was 30.25%. Daily gain, daily feed intake and efficiency of feed utilization were poorer with pigs fed MM as the only protein supplement than with pigs fed any other supplement.

The Difference

Rations containing 10, 20 and 30% of rapeseed meal respectively were fed to Large White turkeys starting at 1 day of age. The results at 56 days showed a significant linear decrease in weight gain and feed utilization when compared with an isocaloric and isonitrogenous corn–soybean basal diet. Steam-pelleting the diets reduced the difference in weight depression observed between the control and rapeseed meal diets as compared with similar diets fed in the form of mash. At 113 days, the levels of rapeseed meal in the diets were reduced in order to maintain desired dietary protein levels. Weight gain and feed utilization were still significantly lower at market age for the rapeseed-fed birds as compared with those on the control diet. Analyzing the weight-gain and feed-utilization data from 57 days to the conclusion of the experiment suggested that most of the adverse effects of rapeseed meal were encountered with birds up to 56 days of age.

Three samples of defatted fine rapeseed screenings meals and defatted stinkweed (Thlaspi arvense) seed meal were used at 5 and 15% (wt/wt) to contaminate low glucosinolate rapeseed meal (LG-RSM). Defatted lamb's-quarters (Chenopodium album) and smartweed (Polygonum spp.) seed meals were also used, at levels of 1.7 and 5% (wt/wt) contamination. The contaminated LG-RSM was included at 15% (wt/wt) in diets fed to female adult mice during a 2-wk preliminary period, pregnancy, lactation and the first 18 days of the second pregnancy. There was a nonsignificant trend (P > 0.05) for the female mice fed stinkweed meal to have the lowest body weight throughout the two pregnancies, although those fed the six contaminants, and the uncontaminated LG-RSM control diet had an equivalent number of offspring born in the two pregnancies and surviving to weaning. Male offspring of mice fed the higher levels of contaminants tended to have a lower (P > 0.05) body weight during the early part of the lactation period. A decreased availability of protein and energy in these diets possibly resulted in decreased milk production. The numbers of blastocysts implanted, embryos resorbed, fetal deaths and malformed fetuses were similar among the dietary treatments.

Daily Gain

Ammoniation (NH3) of canola seed (CS) containing wild mustard seed (WMS) present as a contaminant resulted in reduction of CS glucosinolates but not of WMS hydroxybenzyl glucosinolate or lysine contents. Feeding diets containing 25% CS including 0, 3, 6 and 9% WMS to crossbred barrows from 23 to 57 kg had no effects on average daily gain (ADG) or daily feed intake (FI) but feed:gain ratio (FG) was poorer. Serum triiodothyronine (T3) was unaffected but thyroxine (T4) was depressed by WMS, a result of hydroxybenzyl glucosinolate intake. FI was improved by NH3. This was attributed to reduced concentrations of sinapine and glucosinolates in CS and WMS. Barrows fed from 57 to 100 kg liveweight showed no effect of dietary level of WMS on ADG or FG but 7.2 and 10.8% WMS resulted in leaner carcasses than with 0% WMS. Use of 30% CS in the diet, regardless of WMS level, resulted in fatty acid changes in backfat compared with the control diets. Fatty acids C14, C16, C16:1 and C18 were reduced and C18:1, C18:2 and C18:3 were increased by consuming diets containing 10–12% oil from CS and WMS. Gilts (57–100 kg) fed diets containing 0.2 and 10.5% WMS in CS fed at 30% of the diet had similar ADG but gilts fed the high WMS diet produced leaner carcasses.

The need for sustainable agricultural-production systems has generated demand for effective, nonsynthetic, alternative weed-control strategies. For some vegetable crops there are few herbicide options available, and there is little prospect of new herbicides being registered for vegetable crops. Brassicaceae seed meal, a residue product of the seed oil extraction process, can provide a resource for supplemental nutrients, disease control, and weed suppression. The objective of this study was to evaluate the effect of different Brassicaceae seed meals and application rates on the emergence of wild oat, Italian ryegrass, prickly lettuce, and redroot pigweed, which are some of the major weeds in vegetable production systems. White mustard seed, Indian mustard seed, and rapeseed meals were used with (intact) or without a functional myrosinase enzyme (denatured). Intact white mustard seed meals applied at a rate of 2000 kg ha−1 significantly reduced weed seedling emergence and weed dry biomass compared with intact rapeseed-meal–amended treatments. Indian mustard showed significantly better herbicidal efficacy on the grassy weeds than did white mustard, which was most effective in controlling broadleaf weeds. In all instances, a 1000 kg ha−1 application rate of either Indian mustard or white mustard exhibited greater herbicidal effect than did the 2000 kg ha−1 application rate of rapeseed meal. These results demonstrate that all glucosinolates are not equal in herbicidal effects. The herbicidal effects of the mustard seed meal could offer vegetable growers a new option for weed control, particularly in organic production systems. In practice, it would seem feasible to treat soils with a blend of Indian mustard and white mustard seed meals so that both grass and broadleaf weeds could be effectively controlled.

The objective of this present study was to investigate the effect of feeding fermented mixture of papaya leaf and seed meal (FERM) on the physical and chemical characteristics of meats of the Indonesian indigenous crossbred chicken (IICC). The study was carried out with 300 day-old IICC. The chicks were randomly distributed to five treatment groups, i.e., CONT (control diet based on corn-soybean- diet), FERMA (diet containing 1% FERM), FERMB (2.5% FERM), FERMC (5% FERM) and FERMD (7.5% FERM). Each treatment group consisted of 6 replicates with 10 IICC in each. At week 8, one chick from each replicate was randomly taken and slaughtered. After being de-feathered and eviscerated, samples from breast and thigh meats were obtained. Results showed that the increased levels of FERM was followed by the increased (P<0.05) pH values, moisture and crude protein content of breast meats of the IICC. Dietary incorporation of FERM especially at the level of 2.5% increased (P<0.05) the content of fat in the breast meat of IICC, while further increased levels of FERM did not alter (P>0.05) the fat content of the IICC breast meat. Dietary treatment did not have any effect (P>0.05) on the lightness (L*) values of breast meat of the IICC. The redness (a*) values were higher (P<0.05) in FERMD breast meat than other. FERM diet resulted in lower (P<0.05) yellowness (b*) values in the IICC breast meat. The pH values and moisture content of thigh meat increased (P<0.05) with the increased level of FERM. The WHC decreased (P<0.05) with the elevated levels of FERM in the diets. There was an increase (P<0.05) in crude protein concentration in FERMA as compared to the other meats. Crude fat and ash concentrations in thigh meat were affected (P<0.05) by the treatments. Dietary treatments had no impact (P>0.05) on L* values of thigh meats. Feeding FERM at 7.5% from diets increased (P<0.05) and decreased (P<0.05) the redness and yellowness of meats. In conclusion, dietary inclusion of FERM especially at the level of 7.5% from diets improved the physical and chemical characteristics of the IICC meats.

Oriental mustard seed meal (MSM), a byproduct generated by pressing the seed for oil, exhibits herbicidal properties. In turfgrass, soil fumigants such as methyl bromide are used to control weeds prior to renovation of turf. Environmental concerns have resulted in deregistration of methyl bromide, prompting the need for alternatives. The objective of this research was to determine the effect of MSM on the establishment of selected turfgrass weeds as well as inhibitory effects on establishment of desirable turfgrasses. Greenhouse experiments were conducted in 2006 and 2007 at the University of Missouri. MSM was amended in soil at 0, 1,350 (low), 2,350 (medium), and 3,360 kg ha−1(high) concentrations. Weed species included annual bluegrass, large crabgrass, buckhorn plantain, white clover, and common chickweed. Turfgrass species included: Rembrandt tall fescue, Evening Shade perennial rye, and Riviera bermudagrass. All species were seeded into soil amended with MSM and either tarped or left untarped. All treatments were compared to dazomet (392 kg ha−1), a synthetic standard. Plant counts and biomass of all species were recorded 4 wk after seeding. Overall, tarped treatments suppressed weed emergence 27 to 50% more compared to untarped treatments, except for large crabgrass. High rates of MSM suppressed emergence of all weeds ≥ 63%. Compared to the untreated control, the density of buckhorn plantain, white clover, and common chickweed was reduced by ≥ 42% at low rates of MSM. Biomass of buckhorn plantain, annual bluegrass, common chickweed, white clover, and large crabgrass was reduced from 37 to 99% at high rates of MSM. MSM at high rates reduced stand counts of tall fescue and perennial ryegrass up to 81% and 77% respectively, compared to the untreated control. Regardless of MSM rates or tarping, suppression of common bermudagrass emergence did not exceed 30%; tarped treatments actually increased bermudagrass emergence by 22%. The biomass for tall fescue, perennial ryegrass, and bermudagrass was reduced by 85, 68, and 10%, respectively, at high rates of MSM. For tall fescue, MSM at all rates strongly suppressed seed germination by 7 d after planting (DAP) (up to 100%), with additional germination observed through 14 DAP, but not thereafter. In both trials, dazomet completely suppressed emergence of all weeds. MSM appears to suppress emergence and growth of a number of weeds common in turf, with potential selectivity for bermudagrass.

Transporter Expression

In rodents, a number of intestinal digestive and absorptive processes demonstrate a diurnal pattern of activity. To investigate if the jejunal hexose transporters are regulated in such a diurnal fashion, the levels for the glucose and fructose transporter mRNA and proteins were determined at 6-h intervals over a 24-h control fed period. SGLT-1, GLUT-2, and GLUT-5 mRNA levels increased between two- and eightfold before the onset of peak feeding. GLUT-5 protein levels also varied in a diurnal fashion but were out of phase with the observed changes in GLUT-5 mRNA levels. In contrast, GLUT-2 protein levels remained relatively constant during the control fed 24-h period. The effect of dietary manipulations on the observed diurnal variation was also investigated. After only 3 h of feeding a 60% fructose-enriched diet, the levels of GLUT-5 mRNA and protein were significantly elevated. GLUT-5 mRNA and protein levels remained elevated relative to the level of control diet-fed animals over the ensuing 24 h and during the 7th day of fructose feeding. Exposure to elevated levels of fructose had no significant effect on the diurnal pattern of GLUT-2 and SGLT-1 mRNA. In contrast, GLUT-2 protein was rapidly downregulated during the length of the fructose feeding study. In conclusion, the data demonstrate a normal daily variation in the level of hexose transporter expression that can be rapidly modulated by diet.

Five swine experiments were conducted to evaluate rapeseed meal (RSM) of low glucosinolate content (Brassica napus L. cv. Bronowski). Two experiments involved 0, 25, 50, 75 and 100% substitution of either Bronowski meal or regular (B. campestris) meal for soybean meal or fishmeal used in the control diet. One experiment compared ad libitum-fed and partially restricted pigs. Another experiment involved digestibility studies, and the final one involved methionine and lysine supplementation. As the dietary levels of either Bronowski or regular RSM increased in the ration, protein digestion coefficients decreased from 79 and 80% to 76 and 78%, respectively, and energy coefficients decreased from 82% to 79 and 78%, respectively. The protein and energy digestibility coefficients for Bronowski RSM were estimated to be 68 and 59%; for regular RSM, 65 and 54%. With barley–wheat–RSM diets, pigs responded to 0.1% methionine, but not to lysine (P > 0.05). Pigs fed ad libitum consumed more Bronowski than regular RSM diet and performed as well as pigs fed soybean meal diets.
