“…A marked rise in GOT activity is indicative of organ damage and would provide evidence of Cu toxicosis per se. Failure of dietary Cu to affect SGOT activity, indicated that Cu toxicosis per se was not occurring, and although SN supplementation resulted in increased SGOT activity, levels were well within normal ranges reported in the literature (Dalvi and McGowan, 1984;Madhusudhan et al, 1986). It is concluded that the reduction in performance observed in this study was primarily due to a copper-mediated reduction in feed intake and not to copper toxicosis per se.…”

An experiment was conducted with 576 female Cobb feather-sexed chicks to study the influence of methionine (MET) and selected nutrient (SN) supplementation on the performance of chicks fed high Cu levels. Day-old chicks were allotted randomly to pens for the 22-day experiment. A 3 X 2 X 2 factorial arrangement of treatments was used which included Cu at 0, 400, and 800 mg/kg, MET at 0 and .4%, and SN at 0 and 20%. A significant (P less than .001) Cu X MET X SN interaction was found for gain. Supplemental MET reversed the growth depression observed in birds fed 400 but not 800 mg/kg Cu. Additions of 400 and 800 mg/kg Cu to the basal diet depressed (P less than .001) feed consumption by 8.6 and 19.4%, respectively. Hepatic Cu concentrations increased linearly (P less than .001) with increasing dietary Cu and were not influenced (P greater than .10) by supplemental MET or SN. Liver weights increased linearly (P less than .001) with increasing dietary Cu and were higher (P less than .05) for chicks on diets supplemented with SN, but lower (P less than .05) for those with diets supplemented with MET. The interaction of MET X SN was significant (P less than .001) for serum Cu; chicks supplemented with SN in conjunction with MET had the lowest (P less than .05) serum Cu concentrations. Serum glutamic-oxaloacetic transaminase (SGOT) activity was not influenced (P greater than .10) by dietary Cu, but SN supplementation resulted in a 10% elevation (P less than .001) in SGOT activity.(ABSTRACT TRUNCATED AT 250 WORDS)

“…The increase in liver weight at high levels of CBC might be an attempt by the organ to detoxify theobromine containing diets. Antinutritional factors have been associated with the enlargement of organs like liver and pancreas (Madhusudhan et al, 1986).…”

Odunsi, A.A. and Longe, O.G. 1995. Cocoa bean cake in poultry diets. I. Chemical composition and nutritive value of cocoa bean cake in pullet chick diets. J. Appl. Anim. Res., 7 : 91-97.Cocoa bean cake (CBC) contained 231 g kg-1 crude protein, 165 g kg-1 ether extract, 57.5 g kg-1 crude fibre, 83.7 g kg-1 ash and 22.4 g kg-1 theobromine. 180 commercial pullet starter chicks were randomly allocated to one of 6 dietary treatments consisting of control diet which contained groundnut cake as the main plant protein source and 5 other diets in which CBC supplied 50, 100, 200, 300 and 400 g kg-1 of total dietary protein. Feed and water were provided ad libitum for a period of 9 weeks. Daily feed intake and weight gain decreased a s dietary CBC protein increased. The level of CBC in the diet was strongly correlated with feed efficiency (r=0.92) and liver weight (r=O. 71) but inversely related to heart weight (mO.90) and kidney weight (m0.83). Significant differences (PcO.05) exhibited by blood characteristics showed that PCV, H b and RBC tend to decrease with increasing level of CBC. The efficiency of feed utilisation allowed CBC' to be included in chick starter diets at concentrations up to 200 g kg-1 diet.

“…Many studies have shown that the linolenic acid content of poultry meat and eggs can be increased through increasing the n-3 fatty acid content of poultry diets (Caston and Leeson, 1990;Hargis and Van Elswyk, 1993;Bond et al, 1997). However, flaxseed contains some antinutritional fac-tors that had been reported to decrease performance of birds depending on the dietary levels and form of the plant (whole seed, oil extracted) used in the diet (Madhusudhan et al, 1986;Lee et al, 1991).…”

Dietary camelina meal versus flaxseed with and without supplemental copper for broiler chickens: Live performance and processing yield

et al. 2009

An experiment was conducted to compare the responses of young broiler chickens to corn-soybean meal diets supplemented with flaxseed or camelina meal versus a corn-soybean meal control and the factorial effect of 150 mg/kg of Cu supplementation on performance and processing yield. A randomized complete block design with a 2 x 3 factorial arrangement was used with 7 replicates from hatch to 21 d of age (n = 294; 7 chicks per replicate). Body weight of birds fed 10% camelina meal or 10% flaxseed was significantly reduced compared with the control birds. Addition of Cu significantly increased BW and feed consumption of the birds fed the control diet throughout the study. Copper supplementation to the 10% camelina meal diet also increased BW (P < 0.001) with no effect on feed consumption or feed conversion at 21 d. In addition, hot carcass weight, yield, and carcass parts were significantly improved among birds fed the Cu-supplemented control diet. A significant Cu x diet interaction was observed for hot carcass weight and yield, indicating Cu supplementation to the control diet was superior for carcass weight to the other treatments. However, yield was greater for the camelina diets and the control + Cu versus the other treatments. Results from the present study demonstrated that either 10% camelina meal or 10% flaxseed diets will reduce broiler BW when fed the first 3 wk of life. However, birds fed the camelina diet responded to Cu sulfate supplementation with improved live performance and carcass characteristics. Birds fed the 10% flaxseed diets showed no beneficial effect resulting from Cu supplements.
