“…Bush et al [3] reported the largest fat digestibility was observed when horses were fed 15% dietary fat, while treatments of 5% and 10% fat were not different from 0%. Delobel et al [5] concluded that the addition of linseed oil increased fat digestibility by 26.4%. Estimates of apparent digestibility of fat by ponies were 42 to 49% for forage and 88 to 94% of supplemented fat and oil [16].…”

“…However, several earlier studies [2][3][4] examined the effects of corn oil, up to 15% of the total diet, finding no effect on digestibility of fiber. Nevertheless, a later study by Delobel et al [5] reported the inclusion of fat at 8 % had a positive effect on NDF.…”

Horse diets are often supplemented with dietary fat to increase caloric intake, and although the effects of fat on fiber digestibility have been studied, this research has not included the use of cannulated subjects. A decrease in fiber digestibility due to fat would be detrimental to equine performance, and thus, the current study utilized cannulated ponies as an equine model for any effects on fiber digestibility due to supplemental dietary fat on a forage diet. Five Shetland/hackney pony mares with an ileal and cecal cannula were fed hay, 2 kg/d alfalfa pellets and vegetable oil at 0, 5, 10 or 15% of total diet. Experimental diets were fed twice a day at 0600 and 1600 hours. Ponies were allowed a 14-d diet adjustment period, after which ileal and cecal cannula samples and fecal grab samples were collected at 1, 3 and 5 d post diet adjustment. On day 1, samples were taken at 0, 90, 180, 270 min and 7 and 10 h. Day 3 samples were taken at 30, 120, and 210 min, and 5 and 8 h. On d 5 samples were taken at 60, 150, and 240 min and 6 and 9 h post feeding. Samples were analyzed for crude protein, fat, acid-detergent fiber, acid-detergent lignin, and apparent digestibility of dry matter, crude protein, fat, and acid-detergent fiber. No effects were found on fiber digestibility due to fat supplementation up to 15% of the total diet in a pony model (P > 0.1). Results indicated that equine diets could be supplemented with up to 15% of fat in the form of vegetable oil to increase digestible energy with no negative impact on fiber digestibility.

A standardised methodology is required for classification of starchy diets. One important question is what feeding status is optimal to describe glycaemic and insulinaemic responses to the respective starchy diet. Four horses were fed, in a randomised order, four different feeding protocols relative to offering hay before or after cracked corn (CC): (i) ad libitum hay for 12 h before feeding CC and ad libitum hay after CC intake for 9 h (1CC1), (ii) ad libitum hay for 12 h before feeding CC and no hay after CC intake for 9 h (1CC2), (iii) feed restriction for 12 h before feeding CC and ad libitum hay after CC intake for 9 h (2CC1) and (iv) 1.2 kg hay/100 kg body weight (BW) per day, divided into two equal portions and offered at 0900 h and 1900 h, feed restriction for 12 h before feeding CC and no hay after CC intake for 9 h (2CC2). CC intake was adjusted to a starch intake of 2 g/kg BW. The different hay offerings did not affect basal plasma glucose and insulin levels. A significant rise in plasma glucose and insulin was found after CC intake for all diets. The highest peak glucose levels were analysed for 2CC1, and the lowest glucose peaks were found for 1CC2 (diet P , 0.05). The highest insulin peaks were monitored for 2CC1 (31.27 6 18.19 mU/ml) and lower peaks for 1CC2 (13.36 6 2.93 mU/ml) (diet P , 0.05). Insulin for 2CC2 and 1CC2 returned to resting values about 300 min after CC feeding. For 1CC1 and 2CC1, insulin levels were still above resting levels 510 min after CC intake (diet P , 0.05). The present data suggest that feed restriction for 12 h before feeding the starchy diet and no further roughage intake during blood sampling period provide the best-defined conditions. Keywords: feed restriction, starch intake, glucose, insulin, horses Implications A standardised methodology is required for classification of starchy diets (e.g. grain processing techniques) on glycaemic and insulinaemic responses in horses. Differences in results obtained for horses might be due to differences in experimental protocols. The present data suggest that feed restriction for 12 h before feeding the starchy diet and no further ingestion of roughage during the blood sampling period provides the best-defined conditions. Hay is a very heterogeneous feedstuff (e.g. large differences in nutrient composition or total amount of hay consumed during ad libitum access); therefore, a precise description of the side effects of hay composition on metabolic responses is hard to define. IntroductionIn horses, several studies have been conducted to describe glycaemic and insulinaemic responses to a starchy meal with a focus on grain origin (Stull and Rodiek, 1988; JoseCunilleras et al., 2004;Rodiek and Stull, 2007), different grain processing techniques (Vervuert et al., 2003(Vervuert et al., , 2004(Vervuert et al., , 2007(Vervuert et al., and 2008a or the interaction between starch and other nutrients like fiber (Stull and Rodiek, 1988;Radicke et al., 1994;Pagan and Harris, 1999;Harris et al., 2005;Vervuert et al., 2008b and2008c) or fat (...

“…In the last years there have been a growing interest for food and feeding components, of conventional use or not, that present claims of functionality to the prevention and control of non-transmissible illnesses and chronic aggravations. Among these foods are linseed, sesame, oats and sunflower seeds, because the linseed (Linum usitatissimum L.) is a source of essential fatty acids, fibers and phenolics, known by their antioxidant activity (8); the sesame (Sesamum indicum) contains proteins, vitamins and minerals (9); the oats (Avena sativa L.) are rich in fibers, proteins and lipids (10); and the sunflower (Helianthus annuus) is rich on polyunsaturated fatty acids, with prominence to linoleic acid (11). The present study evaluated the effect of the multimixture-supplemented diet containing oat bran, linseed, sesame and sunflower seed on the hepatic function and antioxidant activity in diabetic rats.…”

ResumenIntroducción: alimentos y componentes de la dieta han recibido considerable atención como recursos auxiliares en el control de las enfermedades crónicas, como la diabetes. Este estudio evaluó el efecto de la dieta suplementada con base de linaza multimezcla, sésamo, avena y semillas de girasol en la función hepática y la actividad antioxidante de ratas diabéticas. Métodos: las ratas macho fueron divididas en grupos de siete animales: control de la diabetes (CD), diabéticos sometidos a dieta multimezcla (DM), diabéticos con insulina (DI), y control normal (CN). El tratamiento se inició en el quinto día después de la inducción de la diabetes con estreptozotocina 40 mg/kg i.v. en tampón citrato y se mantuvo durante 50 días. Resultados: la dieta extracto etéreo complementado tenía el contenido fenólico más alto (p < 0,05) que los otros extractos de la suplementación de la dieta y el extracto de éter de la comida estándar. No hubo diferencia en la actividad antioxidante in vitro de la alimentación usada. A medida que las transaminasas, los niveles de ALT signifi cativamente mayor (p < 0,05) estuvieron presentes en el grupo de diabéticos en comparación con CN, el peso relativo del hígado en el grupo de diabéticos fue signifi cativamente mayor (p < 0,001) en comparación con el grupo CN. Los grupos sulfhidrilo de los niveles de proteína no fueron signifi cativamente mayores (p < 0,05) en los grupos F e I comparados con CN y CD. El tratamiento con insulina resultó en una mejora de la actividad antioxidante con respecto a la catalasa hepática. Conclusión: la suplementación con multimezcla no mejora el control metabólico de la diabetes. El tratamiento con multimezcla aislado mostró una mejora en la actividad antioxidante en el tejido hepático, como se evidencia por el aumento de los niveles de grupos sulfhidrilo no proteicos. AbstractIntroduction: Food and dietetic components have received considerable attention as auxiliary feeding resources on controlling of chronic non-transmissible diseases, among them diabetes. This study evaluated the effect of supplementary diet with multimixture based on linseed, sesame, oats and sunfl ower seeds on the hepatic function and antioxidant activity of diabetic rats. Methods: Male rats were distributed on groups of seven animals: diabetic control (DC), diabetics subject to multimixture diet (DM), diabetic with insulin (DI), and normal control (NC). The treatment was started on the 5 th day after diabetes induction with 40 mg/kg i.v. streptozotocin on tampon citrate and kept during 50 days. Results: The ethereal extract of the supplemented diet showed a higher content of phenolics (p < 0.05) compared to other extracts of the supplemented diet and the ethereal extract of the standard diet. There was no difference in antioxidant in vitro activity of the utilized diets. Concerning to transaminases, signifi cant bigger ALT levels (p < 0.05) were present on diabetic groups compared to NC. The relative liver weight on diabetic groups was signifi cantly higher (p < 0.001) compared to NC ...
