“…Lecithin has been widely used in animal diets, such as in sheep (Jenkins and Fotouhi, 1990), lambs (Lough et al, 1991), horses (Holland et al, 1998), fish (Liu et al, 2004), swine (Soares and Lopez-Bote, 2002) and laying hens (Attia et al, 2009a). On the other hand, the use of lecithin in rabbit diets is rare.…”

A total of 28 adult V-line rabbits were fedad libituma control diet or a diet supplemented with 0.5%, 1.0% and 1.5% soybean lecithin (SL) for 12 weeks. Bucks that received 0.5%, 1.0% or 1.5% dietary SL had a higher ejaculate volume, mass motility, sperm concentration, total sperm output and total motile sperm. Dietary SL reduced the percentage of dead sperm and increased the normal sperm, and this concurred with an increase in blood testosterone concentration. Blood and seminal plasma total lipid, acid phosphatase and seminal plasma alkaline phosphatase were significantly increased because of inclusion of SL. Interestingly, SL reduced blood and seminal plasma thiobarbituric acid-reactive substances while increasing blood and seminal plasma glutathione content, glutathione S-transferase, glutathione peroxidase and superoxide dismutase activity. Conception rate and litter size at birth and weaning were also significantly improved. Practically, it could be suggested that SL is a suitable supplement for improving semen quality, antioxidant status, reproductive traits and the economic efficiency of V-line rabbit bucks and 1% is an adequate concentration.

“…Supplemental animal and vegetable fats have been utilized in the equine diet, in the form of vegetable oils, bi-product feeds (stabilized rice bran and wheat germ), along with medium chain fatty acids such as fish oil (menhaden). However, the use of vegetable oils, primarily corn oil, is the most prevalent due to its superior palatability (Holland et al, 1997). The benefits of feeding fat supplemented diets to performance horses are well documented, including increased caloric density, lower heat increment, and a glycogen sparing effect (Webb et al, 1987;Meyers et al, 1989;Julen et al, 1995), although in more recent years, interest has been placed on the fatty acid composition of the diet.…”

Sixteen horses (2 to 4 yr; 357 to 439 kg BW) were utilized in a randomized complete block design for a 140 d trial to determine effect of omega 3 PUFAs (n-3) supplementation on markers of inflammation in young horses in training. Horses were fed treatments consisting of a control diet (n = 8) fed at 1% BW (as fed) or a treatment diet (n = 8) of concentrate fed at 0.75% BW (as fed) and 350 g of a marine n-3 supplement formulated to provide 15 g of eicosapentaenoic acid (EPA) and 20 g of docosahexaenoic acid (DHA). Body weight and body condition scores (BCS) were obtained biweekly and concentrate adjusted accordingly.Horses were exercised 5 d/wk by students in an equine training course. Type of activity and duration was monitored, along with heart rate to quantify workload.

ZusammenfassungIn der vorliegenden Untersuchung sollte die Akzeptanz fettreicher Krippenfuttermittel sowie mögliche Auswirkungen auf die mikrobielle Aktivität im Magen-Darmkanal des Pferdes überprüft werden. Dazu wurde bei 3 jejunumfistulierten und 2 intaKen Ponys nach einer fettarmen Kontrollration (Hafer, Heu) Influence of fat on feed intake and microbial activity in the stomach and small intestine in the horse In 5 horses (3 fitted with permanent fistulas in the jejunum and 2 without fistulas) the acceptance and effects on microbial activity in the intestinal tract of concentrates containing high amounts of fat were investigated. After a control ration with oats and hay, different types of fat (10 % of sunfloweroil, pigfat or tallow) were mixed to the concentrate so that the fat content in the complete rations was 8 %. The feeding time and different parameters of microbial activity in the chyme (lactate, volatile fatty acids, pH) and in the exhalation (H, and CH/ were measured. The following effects were obtained: The addition of fat causes a much longer feeding trme, about twice the time of the control ratron. The activity of lipase in the chyme was about 70 U/9, feeding oil had no effect on the activity of lipase. Fat content in the chyme which was 20 g/kg dry matter in the control increased after supplementation of oil up to 56 g/kg 7 h postprandial. Postprandial lactate in the chyme increased in the control diet and also after the addition of oil with maxima 5 h ppr. (control) and 7 h ppr. (with oil), resp. Generally significant lower concentrations of lactate in the jejunal chyme were observed with additional oil. Between lactate (x; mmol/l) and ph value (y) a significant correlation exists: y=7.72-0.02x; r=-0.86.-; n=87. Fat supplementation had no effect on Hr, wheras a slight reduction of CHo in the exhalation air was seen. keywords:Einleitung
