“…Beaudoin (1985), analyzing ruminants receiving diets with cottonseed meal or diets with whole cottonseed cited a reduction in the blood hemoglobin rate. On the other hand, Risco et al (1993) stated that the changes observed in hematological and serum composition of cows fed with 0 or 800 mg of free gossypol (FG kg -1 ) have not been enough to be used as a diagnosis of toxicity. Likewise, Andreazzi et al (1995) did not detect significant difference between the treatments for the blood metabolites in goats fed with 0 or 13.45 mg of FG kg -1 LW.…”

ABSTRACT. This study evaluated the semen quality of Santa Ines sheep fed diets containing different levels of whole cottonseed (WCS). Twenty sheep were distributed into four groups that were given diets with 0; 20; 30; 40% of WCS. For this study the semen was collected by electroejaculation, and a monthly andrological examination was performed during nine months. The analyzed variables were: scrotal circumference (SC), appearance and color of the ejaculate, progressive motility (PM), vigor, mass movement (MM), total sperm concentration (spzX10 9 ), sperm morphology (SM) and blood hematocrit. The SC had no difference among diets, with mean 31.83 cm. The animals fed diets with WCS, presented mean intake of 9.16 mg gossypol kg BW, and were prone to present greenish semen, and appearance ranging from thin creamy to watery. The PM decreased linearly (p < 0.05) with increasing level of WCS, while the vigor had a quadratic trend. The total defects increased linearly in relation to reference values described in literature. The WSC had no influence on hematocrit levels, but did affect the PM and vigor of spermatozoa, thus not recommended to diets of animals for breeding.Keywords: andrological, gossypol, ram, reproduction, sperm motility.Efeito de dietas contendo caroço de algodão sobre a qualidade do sêmen de ovinos RESUMO. Este estudo objetivou avaliar a qualidade do sêmen de carneiros da raça Santa Inês, alimentados com dietas contendo diferentes níveis de caroço de algodão integral (CAI). Foram utilizados 20 carneiros distribuídos em quatro dietas e alimentados com 0, 20, 30, 40% do caroço de algodão integral. Para este estudo realizou-se a coleta de sêmen dos animais pelo método da eletroejaculação e durante nove meses procedeu-se o exame andrológico mensal. As variáveis analisadas foram: circunferência escrotal (CE); volume, aspecto e cor do ejaculado, motilidade progressiva (MP), vigor, movimento de massa (MM), concentração espermática total (spzX10 9 ), morfologia espermática (ME) e hematócritos sanguíneos. A CE não variou entre as dietas com média de 31,83 cm. Os animais que receberam (CAI) tiveram ingestão média de 9,16 mg de gossipol kg -1 PV, e tenderam a apresentar o sêmen de coloração esverdeada, com aspecto variando de cremoso fino a aquoso. Nas características microscópicas a MP decresceu linearmente com aumento do nível de CAI, enquanto o vigor mostrou comportamento quadrático. Os defeitos totais tiveram efeito linear crescente em relação aos valores de referência descritos na literatura. O CAI não influenciou os níveis de hematócritos, porém afetou a motilidade progressiva e o vigor dos espermatozoides, não devendo ser usado em dietas de animais destinados à reprodução.

“…[6] Being inexpensive and rich sources of dietary protein, cottonseed products such as cottonseed meal have long been used in both animal and human diets. [7,8] Cottonseed meal is extensively used as a protein supplement in both ruminant (feeding either as a supplement or in the mixed feed being a common practice in commercial beef and dairy cattle operations [9] ) and monogastric animal rations, including pigs, chickens, horses, pets and catfish. [10] High protein cottonseed flour such as incaprina-cottonseed flour is used to supplement the protein-deficient diets of humans in developing countries.…”

The objectives of the present study were to: (i) examine the in vitro dose response of rabbit spermatozoa motility to the antifertility agent gossypol (GOS) and (ii) determine whether filtered (FIL) and unfiltered (UNFIL) GOS differ in their magnitude of effect. Rabbit semen belonging to adult males (n = 5; 12-14 months) were cultured with UNFIL GOS and FIL GOS (5% solution) and subsequently diluted (1:1-7) for analysis using a Computer Assisted Semen Analyzer (CASA) system in 5 time periods (0, 60, 120, 180 and 360 minutes). At Time 0, no significant change in rabbit spermatozoa motility (MOT) and progressive motility (PROG) with GOS FIL was noted, while increases were observed with GOS UNFIL. At Time 60, weak changes were noted for MOT and PROG. After 120 minutes of culture with both GOS FIL and GOS UNFIL, MOT and PROG decreased significantly in some experimental groups. However, no differences were recorded for both the parameters at Times 180 and 360, with the exception of PROG in the GOS UNFIL category (groups A, B, E, F and G), where a significant decrease was noticed. Detailed evaluation of the distance and velocity parameters revealed reduction in all these studied markers after 60 and 120 minutes of in vitro culture with both GOS FIL and GOS UNFIL, indirectly confirming the PROG decrease. Straightness (STR), linearity (LIN), wobble (WOB), amplitude of lateral head displacement (ALH) and beat cross frequency (BCF) mostly remained unaltered at all time periods for GOS FIL, where as some minor alterations were noticed in GOS UNFIL category for STR, LIN, WOB, ALH and BCF parameters at Time 0, 60 and 120. The present study confirms the dose and time dependent alterations of rabbit spermatozoa motility parameters by GOS. The GOS dynamics in our experiment shows that rabbit spermatozoa as a biological material can indicate a GOS inhibition of motility. Obtained data for the first time indicates a higher immobilizing potential of unfiltered GOS in comparison to filtered GOS in its inhibitory action of spermatozoa motility parameters in rabbits.

“…It is toxic to non-ruminant mammals, birds, and many insects and microbes; in mammals the toxic effects can include reduced appetite, body weight loss and dyspnea (Berardi and Goldblatt, 1980). Gossypol can render lysine metabolically unavailable and impact on the normal functioning of mitochondria (Yannai and Bensal, 1983; Cuellar and Ramirez, 1993;Risco et al, 1993).Although glandless cotton has been developed for food purposes, the plants are more susceptible to pests (Delattre, 1992). Inactivation or removal of gossypol and CPFAs during processing has enabled use of cottonseed meal for catfish, poultry and swine (Jones and Wedegaertner, 1986;Lusas and Jividen, 1987).…”
