“…They concluded that this might be an indicator of gossypol intoxication due to damage of liver cells and, thus, diminished capability of the liver to synthesise urea. In addition, Nikokyris et al (1999) reported that PUN was associated with differences in dietary free gossypol intake. This was obviously not the case in the present study.…”

Four lactating Holstein cows were used in a 4×4 Latin-square design to determine the effects of various levels of whole cottonseed (WCS) in diets on parameters including milk (yield and fat content), rumen fluid (pH, ammonia and TVFA) and blood (βcarotene, vit. A, vit. E, urea, NH 3 , Ca, P and Mg levels). Cows consumed 0, 1, 2 or 3 kg WCS per day. No significant differences were observed among the groups on analysed parameters except plasma vitamin E concentration. In addition, when the amount of cottonseed was increased, milk yield and milk fat content also tended to increase but this increase was not statistically significant. In conclusion, feeding of WCS up to 3 kg per day with ad libitum maize silage did not cause negative effects on milk yield, milk fat and blood vitamin levels in the short term in dairy cows.

“…It is a membrane-active agent with cytocidal properties and inhibits membranebound enzymes, thus causing haemolytic anaemia at high concentrations in mammals. Gossypol can cause cytotoxic effects, such as occurrence of hypokalaemia in animal models and increase in red blood cell fragility (Fu et al 1988;Colin-Negrete et al 1996;Randel et al 1996;Nikokyris et al 1999).…”

Two feeding experiments were conducted to evaluate the potential of fermented soybean meal (FSBM), corn gluten meal (CGM) and cottonseed meal (CSM) with or without lysine (L) and iron (Fe) to replace fish meal (FM) in practical diets of juvenile Chinese sucker. In experiment I, four experimental diets (430 g kg−1 crude protein on dry matter basis) were formulated. Diet containing FM as the main protein source was used as a control (Diet 1). Diets 2–4 had 300 g kg−1 FM protein replaced with FSBM, CGM or CSM protein without iron or lysine supplement. Fish (average weight, 1.82 ± 0.01 g) were hand‐fed twice daily for 8 weeks. In experiment II, juvenile Chinese sucker (average weight, 3.40 ± 0.08 g) were fed one of five experimental diets twice daily for 8 weeks. Diet 1 in experiment I was used as a control and Diet 4 in experiment I, with ferrous sulphate, with lysine or with both ferrous sulphate and lysine were used as the experimental diets (designated as FM, CSM, CSM+Fe, CSM+L and CSM+Fe&L, respectively). Results from the two feeding trials indicated that about 300 g kg−1 of FM protein can be replaced by FSBM, CGM or CSM with lysine supplement in Chinese sucker diets without adversely affecting growth. CSM with iron could not improve the growth performance. CSM without lysine supplement significantly affected the growth performance, body composition and digestive enzyme activities.

“…Free gossypol is a membrane active agent with cytocidal properties and has the ability to inhibit membrane bound enzymes, causing hemolytic anemia at high concentrations in mammals. The cytotoxic effects of gossypol include increase in red blood cell fragility and accurrence of hypokalaemia in animal models (Colin-Negrete et al, 1996;Randel et al, 1996;Nikokyris, et al, 1999). Rinchard et al (2000) showed that haemoglobin and haematocrit decreased significantly when adult rainbow trout, Oncorbynchus mykiss, were fed a diet containing 100% CSM protein as fish meal protein replacement.…”

“…It has been shown that free gossypol traps iron causing anaemia and erythrocyte fragility (Nikokyris et al 1999). In swine, gossypol feeding resulted in iron deficiency anemia, because of binding of iron by the gossypol, which resulted in low Hb and Ht and the high iron-binding capacity of blood serum (Nikokris et al, 1999).…”

ABSTRACThe present experiment was conducted to evaluate the effect of α-tocopherol as an antioxidant for avoiding the side effects of incorporation of cottonseed meal (CSM) in the diet of the Nile tilapia as a replacer of fish meal (FM). Two diets were prepared; the first one contained fish meal and was considered as a control, in the second diet, FM was completely replaced by CSM. The second diet was divided into ten parts, the first one is a control and the other 9 diets were enriched with increased levels of vitamin E (1, 5, 10, 15, 20, 25, 30, 35 and 40 times of gossypol in CSM). Each diet was offered in three aquaria (3 replicates for each diet) and each aquarium was stocked with 25 fish (2.0-2.1g). Results are summarized in the following: -The highest average body weight (9.91 g) was recorded for the control group fed on the basal diet (contained FM) and the lowest BW (5.66 g) was obtained for fish fed the diet D2 in which FM was completely replaced by CSM without vitamin E. Incorporation of vitamin E in the experimental diet significantly improved the BW. Similar trend was observed for the other growth performance parameters body length (BL), weight gain (WG) and specific growth rate (SGR). -The best feed conversion ratio (FCR) was recorded for fish group fed on the diets D1 and D3 which significantly differed from values recorded for the other treatments. The worst FCR was recorded in fish group fed on the diet D2 in which FM was completely replaced by CSM without addition of vitamin E. Incorporation of vitamin E in the experimental diets improved FCR specially fish group fed on the diet D3. -Protein content of the whole fish body ranged between 41.33 to 50.97% and the differences were significant. Fat content of fish fed the diet D2 significantly higher than those obtained for fish fed the other groups. Compared to the two control diets D1 and D2 all vitamin levels in the experimental diets increased ash content of the fish whole body and the graded levels of vitamin E in the diets significantly altered the ash content of tilapia fish. -The highest values for hematocrite (Ht) and haemoglobin (Hb) were obtained for fish fed on the control diet (D1). Incorporation of vitamin E in the experimental diets at increasing levels significantly affected Hb and Ht. Compared to the control group (Diet1) aspartate transaminase (AST) and alanine transaminase (ALT) levels significantly increased fish groups fed on the other experimental diets.
