Apparent digestibility coefficients and serum parameters were measured to evaluate the effect of supplementing feed concentrates with rice bran oil in horses. Twelve horses (6 males and 6 females) with a mean age of 18 ± 4 months old and mean live weight of 306 ± 22.6 kg were used. Treatments consisted of increasing rice bran oil concentrate levels of 0, 3.5, 7.0, 10.5, 14.0 and 17.5%, considering a daily intake of 2.25% live weight on a dry matter basis. A dietary effect of supplementation on the apparent digestibility of gross energy (y = 64.55 - 0.58x) was observed (P<0.05). No effect on the other nutrients was observed (P>0.05). Supplementation did not affect serum glucose levels (P>0.05), but cholesterol was affected (P<0.01) based on the interaction of the treatment x gender parameter in females (y = 73.92 + 2.08x). However, no effect was observed in males (P>0.05). A dietary effect on the triglyceride (y = 15.73 - 0.96x + 0.0524x²) and HDL (high-density lipoprotein) (y = 45.24 + 1.0499x) parameters was observed (P<0.01). While the use of rice bran oil does affect blood parameters associated with lipid metabolism, rice bran oil levels up to 17.5% concentrate do not negatively affect the apparent digestibility of dietary nutrients.

ABSTRACT The aim of this study was to investigate the effect of odontoplasty on apparent digestibility of diet for horses, consumption time, and particle size of feces. Nine horses were used, aged 14.5±3.3 years and weightng 531±38.7kg. The diet consisted of 1.5% of live weight (LW) in Tifton 85 hay and 0.75% of LW in concentrate for both assays. The experiment consisted of two tests of apparent digestibility using the method of total collection, before and after the odontoplasty, where the consumption time of hay and concentrate was also evaluated and the particle size of the feces was analyzed. An effect (P<0.05) of odontoplasty on the apparent digestibility coefficients of dry matter, organic matter, crude protein, neutral detergent fiber and acid detergent fiber was observed. Effect of the consumption time for the concentrate (P<0.05) was observed, but not for the forage (P<0.05). There was more retention (P<0.05) of the fecal particles in the sieves of bigger granulometry. The odontoplasty increases the digestibility of dietary nutrients and feces particle size, without changing feces quality. Animals after the procedure have shorter concentrate consumption time.

Ginger Rhizome

The responses of growing rabbits to varying levels of ginger rhizome powder (GP) supplementation were investigated. 72 growing rabbits were divided in 4 groups with each group replicated thrice. Rabbits in each group received commercial diet supplemented with GP at a rate of 0 g (T1), 5 g (T2), 10 g (T3) or 15 g/kg feed (T4) in a completely randomized design for 12 weeks. Quadratic regression equation was used to determine GP supplementation for optimum production variables. Results indicated that rabbits on diet T4 gained weight with lesser feed intake (FI), whereas rabbits on diet T2 had the best feed to gain ratio. Rabbits on diets T2 and T3 recorded higher (p less than 0.05) glucose levels compared to those on the other two diets. Higher (p less than 0.05) cholesterol, triglycerides, high-density lipoprotein (HDLP) and low-density lipoprotein (LDLP) were recorded for rabbits on diet T4 compared to those on diet T1. Rabbits on diet T1 had (p less than 0.05) lower potassium level than rabbits on diets T2 and T4. Alkaline phosphatase (ALP) level was lowest for rabbits on diet T3, which differed (p less than 0.05) significantly from rabbits on the other three diets. The results indicated that GP supplementation at 2.601, 2.826, 2.047, 0.148, 0.774, 0.792, 0.266, 1.363 and 2.443 g/kg feed supported the optimum live weight, FI, glucose, cholesterol, triglyceride, HDLP, LDLP, potassium and ALP level, respectively in growing rabbits. The above-mentioned findings indicate that GP supplementation on rabbit diets enhanced production variables.

Abstract Mandelman, J. M., and Farrington, M. A. 2007. The physiological status and mortality associated with otter-trawl capture, transport, and captivity of an exploited elasmobranch, Squalus acanthias. ICES Journal of Marine Science, 64: 122–130. To assess the physiological responses and associated mortality in spiny dogfish (Squalus acanthias) following capture in an otter trawl and exposure to additional conditions, blood samples were obtained subsequent to three sampling intervals: capture (T1), transport (T2), and captivity (T3). The results indicate that marked differences existed in blood chemistry at each sampling interval. Acid–base parameters (vascular pH, pO2, pCO2), serum Ca2+ and Cl−, and haematocrit were maximally disrupted at T1, but progressively resolved to presumed basal values by T3. Concentrations of whole-blood lactate, plasma total protein, additional sera electrolytes (Na+, K+, Mg2+), and BUN (urea) were maximally compromised at T2, but also recovered by T3. In contrast, serum glucose levels were similar at T1 and T2 but rose to peak levels by T3. Although blood parameters were substantially altered, dogfish mortality was low (2 out of 34; 5.9%), suggesting a strong degree of resilience to compounded stressors associated with capture, transport, and captivity.

This trial was performed to determine the effect of rice bran oil (RBO) inclusion in diets of broiler chickens on performance, carcass characteristics, blood parameters, meat quality, antioxidant activity, liver lipid content, and liver histological structure. The 35-day feeding trial was conducted on 240 one-day-old Ross 308 broiler chickens, allocated to four treatment groups with six replicates each. RBO was examined at different inclusion levels, 0% (control), 1% (RBO1%), 1.5% (RBO1.5%), and 2% (RBO2%) in a completely randomized design. The results showed that at the end of the trial (35 days) the RBO supplementation had positive effects (p < 0.001) on the productivity parameters, but the feed intake was linearly decreased due to RBO inclusion. In addition, RBO supplementation linearly improved (p < 0.05) the dressing percentage, breast yield, immune organs relative weights, and meat glutathione concentration, while it decreased (p < 0.01) the abdominal fat yield and meat crude fat, triglycerides, cholesterol, and Malondialdehyde (MDA) contents in broiler’s meat. Moreover, serum total protein, globulin, and high-density lipoprotein contents improved noticeably (p < 0.01) due to offering an RBO-supplemented diet, but serum total lipids, total cholesterol, triglyceride, low-density lipoprotein, and aspartate aminotransferase concentrations linearly reduced (p < 0.01). The RBO supplementation augmented (p < 0.05) the phagocytic index, phagocytic activity, and antibody titer compared to control. On the other hand, RBO inclusion had no effect on the breast, thigh, or abdominal fat color parameters. Moreover, RBO supplementation reduced (p < 0.01) the content of total saturated FA (SFA), but increased (p < 0.01) the content of total monounsaturated FA (MUFA), and polyunsaturated FA in both breast and thigh meat. Chemical analysis of the liver tissue samples revealed that the inclusion of RBO linearly reduced (p < 0.05) hepatic cholesterol, triglyceride, and MDA contents. Histologically, the lipid percentage and number of lipid droplets (p < 0.01) were markedly lessened in the RBO-supplemented groups. The histological structure of the liver asses by light and electron microscope were normal in all groups without any pathological lesions. It is concluded that RBO could be used as a valuable ingredient in broiler chickens’ diets to stimulate the growing performance and immune status, enhance the antioxidant activity and blood lipid profile, augment liver function, and improve the nutritive value of the meat.

Aim: Hydroxychloroquine (HCQ) could form an alternative treatment for thrombotic primary antiphospholipid syndrome (t-PAPS) if HCQ is proven to reduce the risk of thrombosis. We investigated whether HCQ affects immune response and lipid metabolism in t-PAPS. Methods: HCQ at 400mg/day was given to anticoagulated t-PAPS patients for 6 months. After HCQ withdrawal and a wash-out period of 6 months, the same patients were followed for further 6 months. Blood samples taken at baseline and at the end of each 6-months follow-up period were analyzed employing flow cytometry and biochemical assays. Result: Twenty-seven patients were included, mean age was 44 years, 78% were female, 44% had hypertension, 44% dyslipidemia, 7% diabetes, 77% had venous thrombosis, 30% arterial thrombosis and 33% recurrent thrombosis. Triple aPL positivity was detected in 37%. Lymphocyte counts decreased during HCQ use (mean change -318/mm3; 95%CI -438 to -198) and were not changed during non-HCQ use period. CD8+ and CD4+ cells decreased during HCQ treatment and remained unchanged during non-treatment period. In contrast, TREG (FoxP3+) cells increased during HCQ treatment (mean change 0.2U; 95%CI 0 to 0.4) and decreased in the period of non-HCQ treatment (mean change -0.6U; 95%CI -0.9 to -0.1). Serum glucose, total cholesterol and low density lipoprotein cholesterol decreased during HCQ use (7%, 9% and 12% respectively) and did not change substantially during non-HCQ period. Conclusion: HCQ reduces cytotoxic T lymphocytes, increases regulatory T lymphocytes and decreases LDL cholesterol and serum glucose levels in t-PAPS. These HCQ may contribute to reduce the risk of thrombosis. Disclosures No relevant conflicts of interest to declare.

SummaryFour digestibility and balance experiments were carried out in which 33 growing heifers were fed basal diets of low dry matter silage offeredad libitum, supplemented with various levels of barley and/or groundnut meal or urea.Voluntary intake of the silages was low although apparent digestibility of D.M. was high (66–75%). There was a significant linear negative relationship between the intake of D.M. as supplement and silage D.M. intake.Apparent digestibility of crude fibre in the silages was high (74–83%). It was depressed significantly by addition of barley but not by addition of groundnut. There was a highly significant linear relationship between the digestibility of D.M. and G.B. in the mixed silage concentrate diets used.Metabolizable energy (M.E.) values for the silages varied from 2·04 to 2·52 Mcal/kg (8·5–10·5 MJ/kg) D.M. Supplementation with barley at approximately 1% of live weight, increased M.E. values of the mixed diets to 2·57–2·85 Mcal/kg (10·8–11·9 MJ/kg) D.M. Additional N had little effect on these values.Nitrogen retention was significantly increased in all experiments by barley supplementation. It was further significantly increased by groundnut in three experiments and by urea in one experiment.Multiple regression analysis showed that N retention was significantly related to both M.E. intake and intake of absorbed N, and to M.E. intake and intake of supplementary N.Apparent availabilities of Ca and Mg in silage based diets were low and the availability of Na varied with Na intake. Supplementation with either energy or nitrogen increased apparent availability and retention of Mg but did not exert consistent effects on availability or retention of Ca or Na.There was a highly significant linear relationship between ingested and digested Na but not for Ca or Mg. There was a highly significant linear relationship between absorbed and retained Ca and Mg, but not for Na.Animals fed second cut silages had rather low blood glucose levels and higher than normal levels of blood ketones.
