“…Addition of cotton seed meals at the rate of 10% in diet replacing soybean meal caused no depression in body weight gain or feed intake except in the dietary treatment containing National check variety of cotton seed meal with high amount of gossypol. Reports are available indicating that lysine is the first limiting amino acid in cottonseed meal (Phelps, 1966;Ryan et al, 1986). However in the present study, depression in growth and feed intake was not observed in the diets containing processed meal from BT, Parental Non-BT and commercial produce cottonseeds.…”

An effort was made to assess comparative production performance in broiler chickens fed diets containing solvent extracted cottonseed meal (CSM) processed from BT and Parental Non-BT lines. Processed meal of national check and commercial produce cottonseeds were also used for comparison. The free gossypol contents were 0.02, 0.02, 0.44 and 0.03% in meals of BT, Parental Non-BT, national check and commercial produce cottonseeds, respectively. Day-old broiler chicks (n=243) were divided to 27 groups of 9 each. Nine dietary treatments (iso-nitrogenous, 23% CP and iso-caloric, 2,800 kcal ME/kg) were formulated viz., D1 (control, soybean meal-SBM based), D2 and D3 (BT CSM at 10% of diet with and without additional iron), D4 and D5 (non-BT CSM with and without additional iron), D6 and D7 (national check CSM with or without additional iron), and D8 and D9 (commercial produce CSM with or without additional iron at 2 ppm for every 1 ppm of free gossypol, respectively). Each dietary treatment was offered to three replicated groups up to 6 weeks of age. At the end of 6 weeks of age, 10 birds were taken out randomly from each treatment and were sacrificed to study carcass traits, organs' yield and histo-pathological changes in vital organs. The broiler chickens received CSM processed from BT (D2, 1,753 g and D3, 1,638 g) and Parental Non-BT (D4, 1,653 g and D5, 1,687 g) with or without additional Fe grew at same rate as observed in soybean meal (solvent ext.) based diet (D1, 1,676 g). The feed intake and feed conversion efficiency (feed: gain) in these dietary treatments (BT, non-BT line based diets) also did not differ significantly (p>0.05) from control diet. Similar observation was also observed in dietary treatments (D8 and D9) containing solvent extracted cottonseed meal of commercial produce origin. However, a decrease (p<0.05) in body weight gain and feed intake was observed in D6 containing national check CSM with high gossypol content. Addition of Fe in the diet (D7) improved (p<0.05) feed intake and weight gain but not to the extent as observed in diets containing BT, parental non-BT, and commercial produce CSM or control. However, any type of CSM did not affect feed conversion efficiency when fed with or without additional iron. The carcass characteristics in terms of dressing percentage, liver weight and heart weight was not significantly (p>0.05) different between the treatments. The eviscerated yields emanated from diets containing either BT, non-BT or commercial produce were statistically similar to control. However, eviscerated yield of broilers fed national check CSM with or without iron supplementation was lower (p<0.05) than BT cotton with Fe supplementation and commercial produce CSM. The study envisaged that BT, parental non-BT and commercial produce solvent extracted cottonseed meal can be included at 10% in soybean meal based broiler diet replacing soybean meal and rice bran without additional iron.

“…However, in present study, the diets were formulated on digestible AA basis (Table 2), the depression in BW was probably not because of problem raised by lysine. Also decreased BW gain by increasing lysine disagreed with a general concept that the BW gain was improved with increased dietary lysine (Fisher and Quisenberry, 1971; Ryan et al., 1986). Excessive digestible lysine has been reported to negatively affect the BW gain, feed intake and feed:gain ratio when it was increased above 1.14% from day 1 to 21 of age (Lana et al., 2005a) and 1.02% in conventional diet from day 22 to 42 of age which corresponds to absolute intake of 28 g (Lana et al., 2005b).…”

“…Lysine is the first limiting AA in CSM (Grau, 1946; Anderson and Warnick, 1966; Fisher and Quisenberry, 1971; Ryan et al., 1986). It is typically less ‘nutrient dense’ than SBM, generally providing 40–42% CP versus 48% for SBM (Watkins et al., 1994) in addition to its low protein digestibility.…”

The response of broiler chickens to two levels of endo-1,4-beta xylanase (EC 3.2.1.8) and endo-1,3-beta glucanase (EC 3.2.1.6) combination (with and without), three levels of digestible lysine (0.8%, 0.9% and 1.0% with the applicability of ideal protein concept) and two levels of cottonseed meal (CSM; 20% and 30%) were evaluated in 2 x 3 x 2 factorial arrangement. A total of 2448 male Hubbard broiler chicks were fed on practical vegetable-based mash diets having 2750 kcal metabolizable energy (ME) per kg and 18.5% crude protein (CP) from the age of day 1 to 42. The supplemental enzyme had minimum 1100 units of endo-1,4-beta xylanase and 100 units of endo-1,3-beta glucanase/kg of finished diet. The addition of CSM at 30% resulted in increasing arginine to lysine ratio. A decrease in dressing and breast percentages were observed by the addition of 30% CSM. The digestible lysine at 1.0% decreased the body weight (BW) gain and lowered the mortality during day 1 to 21 whereas the BW gain and feed:gain ratio were unaffected among the three digestible lysine levels during day 1 to 42. The antibody titres against Newcastle and infectious bursal disease viruses were improved with the increasing levels of digestible lysine. The enzyme supplementation improved the apparent ME and digestibility coefficient of nitrogen when it was used with 30% CSM. No effect of enzyme, lysine, CSM or their interactions was observed on serum iron, gizzard and liver weights or abdominal fat percentage. The results showed that increasing digestible lysine improved the antibody titre but did not improve the growth performance and carcass characteristics; supplemental enzyme failed to show any improvement in performance of birds fed on CSM-based diets.

“…A partir daí foram selecionados estes genes para o desenvolvimento de uma cultivar denominada "glandles" (McMichael, 1960) Em aves, o excesso de gossipol na dieta também pode trazer sérios problemas, como: perda de apetite, depressão da atividade respiratória, anemia, edemas pulmonares, hipertrofia do fígado e necrose muscular cardíaca (Barbosa & Gattás, 2004). O principal problema do gossipol na avicultura de postura é na coloração da gema, problema esse que ocorre principalmente no período de estocagem dos ovos (Ryan et al, 1986). Attanayaka et al (2016) observaram que aves alimentadas com maiores teores farelo de semente de algodão apresentaram menores valores de ganho de peso e de carcaça.…”

Os metabolitos secundários também conhecidos como fatores anti-nutricionais, nada mais são do que componentes naturais responsáveis por exercerem funções fisiológicas nos vegetais. São substâncias que, mesmo em estado vestigial, reduzem ou impedem a utilização de um elemento nutritivo, seja no nível digestivo, ou no nível metabólico. Entretanto devido a relevante importância na nutrição animal que alguns ingredientes exercem, estes precisam passar por um processo químico ou físico para viabilizar seu uso na nutrição animal, sem, entretanto, ter que "sofrer" com efeitos adversos do consumo excessivo de determinados compostos secundários. Deste modo, a presente revisão tem como objetivo elucidar sobre as estratégias para diminuição dos efeitos inerentes aos fatores antinutricionais na dieta dos animais. O tratamento térmico, extrusão, peletização e moagem são métodos muito utilizados para redução e/ ou inativação de substâncias indesejáveis em alimentos. Além disso, alguns animais naturalmente e evolutivamente desenvolveram estratégias para conviver com estes fatores.
