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.

Fishy Odor

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.

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.

Two experiments were conducted in which the effects of including in the ration free choline, supplied as choline chloride or as hydrolyzed sinapine (ester of sinapic acid and choline), and bound choline, supplied as sinapine from rapeseed meal, on the fishy odor and the trimethylamine (TMA) content of eggs laid by brown-shelled egg layers were assessed. The results indicated that at the levels fed, free choline does not cause the production of fishy eggs; however, 57% of the eggs produced by the birds fed a comparable level of bound choline in the form of sinapine had a fishy odor and contained appreciable amounts of TMA.

Poultry Diets

In response to queries regarding the long-term effect of utilizing rapeseed gums in poultry diets, an experiment was initiated in which this product was continuously fed throughout the life cycle of the laying hen. Treatments consisted of: (1) soybean meal control, (2) 15% Tower rapeseed meal (3) 15% Tower rapeseed containing 1.5% of rape gums (4) soybean meal containing 1.5% of rape gums, and (5) soybean meal containing 1.5% of soy gums. The meals containing gums were manufactured in Western Canada. The diets were offered to one commercial White Leghorn and University strains of White Leghorns and Rhode Island Red, with conventional dietary specifications used in relation to age of bird. Gums had no persistent effect on feed intake or body weight of pullets from day of age to 20 wk. During this period mortality was low and not influenced by diet. In a subsequent laying period of 308 days, these same dietary treatments had no significant effect on egg production, while breed differences influenced all parameters measured. The addition of gums to rapeseed meal caused a reduction in egg size for a commercial strain of White Leghorns while the converse was true for a Guelph strain of White Leghorns. This apparent dichotomy may have been related to differences in feed intake. Diet had no influence on fertility or hatchability or on the performance of subsequent offspring when these were fed diets comparable to those of their dams. It is concluded that no toxic effects in terms of productive performance accrue from the use of up to 15% Tower rapeseed meal which contains 1.5% rapeseed gums, when fed throughout the commercial life cycle of egg strain birds and their offspring. Performance data also indicate that the addition of such gums to soybean meal offers an alternative means of their disposal.

Abstract The AMAGuides to the Evaluation of Permanent Impairment (AMA Guides) is the most widely used basis for determining impairment and is used in state workers’ compensation systems, federal systems, automobile casualty, and personal injury, as well as by the majority of state workers’ compensation jurisdictions. Two tables summarize the edition of the AMA Guides used and provide information by state. The fifth edition (2000) is the most commonly used edition: California, Delaware, Georgia, Hawaii, Kentucky, New Hampshire, Idaho, Indiana, Iowa, Kentucky, Massachusetts, Nevada, North Dakota, Ohio, Vermont, and Washington. Eleven states use the sixth edition (2007): Alaska, Arizona, Louisiana, Mississippi, Montana, New Mexico, Oklahoma, Pennsylvania, Rhode Island, Tennessee, and Wyoming. Eight states still commonly make use of the fourth edition (1993): Alabama, Arkansas, Kansas, Maine, Maryland, South Dakota, Texas, and West Virginia. Two states use the Third Edition, Revised (1990): Colorado and Oregon. Connecticut does not stipulate which edition of the AMA Guides to use. Six states use their own state specific guidelines (Florida, Illinois, Minnesota, New York, North Carolina, and Wisconsin), and six states do not specify a specific guideline (Michigan, Missouri, Nebraska, New Jersey, South Carolina, and Virginia). Statutes may or may not specify which edition of the AMA Guides to use. Some states use their own guidelines for specific problems and use the Guides for other issues.
