Two experiments were conducted to study the effects of supplementing a laying ration containing rapeseed meal (RSM) with antibiotic drugs on the fishy odor and trimethylamine (TMA) content in eggs laid by brown-egg layers. Brown-egg layers (Rhode Island Red) which had been previously found to lay eggs with a fishy odor when fed a ration containing 10% RSM were used in these studies. In exp. 1, a basal laying ration containing 10% RSM was fed to 16 groups of brown-egg layers (12 birds per group) for a pretreatment period of 4 wk. Quadruplicate groups of these birds were then allotted to each of four treatments for a period of 4 wk. These were the basal ration without supplementation with antibiotic, and the basal ration supplemented with either aureomycin (220 g/1000 kg), penicillin (55 g/1000 kg) or with sulfamethazine in the drinking water (1000 g/1000 kg). Eggs produced by birds during the last week of the pretreatment and treatment periods were scored organoleptically for fishy odor and pooled egg samples from each group were analyzed quantitatively for TMA. The results showed that neither fishy odor score nor TMA levels in the eggs produced were affected by the addition of aureomycin or penicillin to the diet or by the inclusion of sulfamethazine in the drinking water. In exp. 2, 10 groups of brown-egg layers (five birds per group) were fed the same RSM-containing basal laying ration for 4 wk. Following the pretreatment period, duplicate groups of the birds were assigned to each of five rations prepared by supplementing the RSM-containing ration with penicillin at levels of 0, 27.5, 55, 82.5 and 110 g per 1000 kg. Eggs produced by the birds during the last week of the pretreatment and treatment periods were evaluated organoleptically for fishy odor and pooled egg samples from individual birds were analyzed for TMA quantitatively. Results obtained indicated that supplementing the RSM-containing laying ration with penicillin had no significant effect on the TMA content of the eggs produced.

An experiment was conducted to study the effect that varying the amount of glucosinolates and free oxazolidinethione (OZT) in a laying diet containing a constant amount of sinapine had on the trimethylamine (TMA) content of eggs and the incidence of fishy eggs from brown-shelled egg layers. Duplicate groups of 10 Rhode Island Red laying hens which had been found to lay fishy eggs when fed a diet containing 10% rapeseed meal (RSM) were fed each of the four experimental diets. The diets consisted of a wheat-soybean-meal-type control diet and three diets to which aqueous extracts of RSM produced from high, medium and low glucosinolate cultivars (Oro, Span and Tower) were added. The extracts were included in the diet at levels of 3.42, 4.4 and 5.0%, respectively, to provide a sinapine content of 0.17%, a level equivalent to that which would result from the inclusion of 10% RSM in the diet. The results showed that the TMA content of eggs produced by the layers fed the diet containing Tower aqueous extract was significantly higher than that of eggs produced by birds fed the diets containing Oro or Span aqueous extracts (P < 0.05). Since the level of glucosinolates in the diets containing Oro and Span aqueous extracts were about seven times that in the diet containing the Tower aqueous extract, it may be concluded that intact glucosinolates do not affect the amount of TMA in eggs from brown-shelled egg layers fed a diet containing a constant amount of sinapine. On the other hand, free OZT in the diet increased the TMA content of the eggs and the incidence of fishy eggs produced by brown-shelled egg layers.

Fishy Odor

Triplicate groups of four Rhode Island Red layers which had been previously found to lay fishy eggs when fed a ration containing 10% of rapeseed meal (RSM) were fed a laying ration, devoid of RSM, to which 0, 0.5, 1.0, 2.0 or 4.0 g of sinapine (as bisulfate) per kilogram of ration was added. Eggs produced were analyzed for trimethylamine and scored organoleptically for fishyness. Inclusion of more than 1 g of sinapine per kilogram of laying ration caused the birds to lay eggs with a fishy odor. The findings suggest that when RSM is included in the ration of such birds, the level of usage should be such that the ration will contain not more than 0.1% sinapine.

The effects of sparging low glucosinolate-type rapeseed meal (Canola meal) with ammonia, in the absence or presence of steam, on its amino acid composition and feeding value for chicks were studied. Sparging treatments had no effects on the amino acid contents of the meals nor were thyroid size or the growth of chicks affected adversely when the variously treated meals were included in diets for chicks at the 20% level. Sparging with steam appeared to increase the available lysine content of the meal and improve its feeding value for chicks. Key words: Canola meal, ammoniation, sinapine, nutritive value, chicks

Broiler chicken is one of the poultry farms whose growth is fast, can meet the needs of meat in the community. To accelerate chicken growth, addition of Antibiotic Growth Promoter (AGP) was added to the beverage. This study aims to analyze the effect of monensin antibiotic administration on weight gain. The research method uses a Completely Randomized Design (CRD), consisting of 4 treatments and 6 replications. P0 Treatment (Control): Basal ration + Water boiled in 1 liter; P1: Basal ration + Boiled water + 0.1 gr / day Antibiotic Monensin in 1 liter of water; P2: Basal ration + Boiled water + 0.5 gr / day Antibiotic Monensin in 1 liter of water; P3: Basal ration + Boiled water + 1 gram / day Antibiotic Monensin in 1 liter of water. Data analysis used ANOVA one way variance and continued with the Least Significant Difference Test (LSD) with a confidence level of 5%. The results of the study by giving various concentrations of monensin antibiotics to broilers had significantly affected ration conversion, drinking water consumption and final weight. The administration of 1 gram monensin antibiotic concentration tends to be better for ration consumption, body weight gain, drinking water consumption and final weight of broiler chickens compared to lower concentrations or controls.

The present study was to evaluate the impact of rapeseed meal (RSM), canola meal (CM), and their mixture substitute for soybean meal on performance of lactating sows and their offspring. In total, 16 Yorkshire×Landrace sows with initial BW 258.87±5.36 kg were used in this trial. The experimental period lasted 30 days. The sows were allotted to one of four dietary treatments (4 sows per treatment): 1) corn-soybean meal (SBM) basal diets; 2) basal diets containing 8% RSM; 3) basal diets containing 8% CM; 4) basal diets containing RSM (4%) and CM (4%) mixture (RSCM). Sows fed with RSM and RSCM diets had a higher (P less than 0.05) body weight loss than sows fed SBM diet. The parity, litter number, piglet survival rate, weaning pig number, backfat, ADFI and estrus interval were not influenced by dietary treatments (P greater than 0.05). The ADG of piglets from sows fed SBM was higher (P less than 0.05) than sows fed RSM at 1 week. After farrowing, the apparent total tract digestibility (ATTD) of dry matter in sows fed with SBM diet was higher (P less than 0.05) than the RSCM group. The ATTD of energy in SBM and CM treatments was higher (P less than 0.05) than that in RSM and RSCM treatments. On the weaning day, the ATTD of nitrogen and energy in SBM treatment was highest (P less than 0.05) than other treatments. In conclusion, inclusion of 8% rapeseed meal, canola meal, and their mixture substitute for soybean meal had negative effects on reproductive performance of lactating sows and their offspring.

The aim of the present study was to assess enteric methane (CH<sub>4</sub>) emissions by crossbred heifers fed a basal ration of low-quality tropical grass supplemented with different nitrogen sources. Four crossbred heifers (Bos taurus × Bos indicus) with an average live weight (LW) of 355 ± 6.01 kg were used in a 4 × 4 crossover Latin square design with four periods of fifteen days each. Basal ration was chopped low-quality tropical grass Pennisetum purpureum fed to cover ~70% of metabolizable energy requirements for maintenance of heifers and it was supplemented with either poultry litter (control ration, T1), urea (T2), canola meal (T3) or soybean meal (T4). Enteric CH<sub>4</sub> emissions of heifers were measured in open-circuit respiration chambers for 23 hours. Dry matter (DM), neutral detergent fibre (NDF) and acid detergent fibre (ADF) intakes decreased when feeding urea (1.6% of ration) as a source of nitrogen (7.64, 3.78, and 1.83 kg/d, respectively). Rations including urea (T2) or canola meal (T3) given to heifers fed a basal ration of low-quality Pennisetum purpureum grass significantly reduced acetic acid concentration and increased propionic acid concentration in the rumen and decreased the loss of gross energy as methane (P = 0.004). Incorporation of urea or canola meal in the ration of cattle fed low-quality tropical grass can decrease methane emissions and improve rumen fermentation patterns.

After herbicide applications for 1–24 yr, there were no detectable residues of glyphosate, dicamba, 2,4-D, bromoxynil or methylchlorophenoxyacetic acid (MCPA) in soil at two long-term tillage sites and one long-term manured site. The only detectable residues in soil were of diclofop and triallate. Residues of bromoxynil, diclofop and MCPA but not dicamba, 2,4-D or triallate, were detected in the groundwater at the manured site. Diclofop was detected in 6% and bromoxynil and MCPA in 2% of 84 water samples collected at the manured site. Maximum concentrations of bromoxynil (6.5 μg L−1) and diclofop (47 μg L−1) in the groundwater at the manured site exceeded levels set by the Canadian drinking water guidelines. Long-term application of herbicides has not caused accumulation of harmful residues in southern Alberta soils, but the presence of certain herbicides in the groundwater at concentrations above the level set by the drinking water guidelines is cause for concern.

Three experiments involving 11 600 male broiler chickens sought to determine if the pelleting process affects the dietary micronutrient, fat and protein components to increase the incidence of sudden death syndrome. Processed dietary micronutrient and fat components were not significantly associated with an increase in sudden death syndrome among broiler chickens. In one of the experiments, the incidence of sudden death syndrome was reduced (P < 0.01) when the dietary protein supplements (soybean meal, canola meal and fishmeal) bypassed the pelleting process.

As an alternative disinfectant to chlorination, electrolytically generated copper:silver (400 and 40 μg/L copper and silver, respectively) with and without free chlorine (0.3 mg/L) was evaluated over a period of 4 weeks in indoor and outdoor water systems (100 L tap water with natural body flora and urine). Numbers of total coliform, pseudomonas, and staphylococci were all less than drinking water standards in systems treated with copper:silver and free chlorine and systems treated with free chlorine alone (1.0 mg/L). No significant differences (p ≤ 0.05) in bacterial numbers were observed between systems with copper:silver and free chlorine and those with free chlorine alone. Overall, free-chlorine treatments (0.3 or 1.0 mg/L) showed significantly lower heterotrophic plate numbers than those without free chlorine. When challenged with a natural Staphylococcus sp. isolate, water with copper:silver and free chlorine had a 2.4 log10 reduction in bacterial numbers within 2 min, while free chlorine alone or copper:silver alone showed 1.5 and 0.03 log10 reductions, respectively. Addition of copper:silver to water systems may allow the concentration of free chlorine to be reduced while still providing comparable sanitary quality of the water. Key words: disinfection, water, copper, silver, chlorine.
