The purpose of this study was to examine the effect of physiological plasma nonesterified fatty acid (NEFA) levels on insulin-stimulated forearm and whole body glucose uptake and substrate oxidation during euglycemia and hyperglycemia. Seven healthy men received Intralipid and heparin for 210 min in two studies, with saline as control in two further studies. Insulin (0.05 U.kg-1.h-1) was infused from 60 min, and euglycemia was maintained during lipid (EL) and control (EC) studies, and hyperglycemia was maintained in the other studies (HL and HC). Forearm NEFA uptake was comparable in the lipid studies (+61 +/- 10 and +52 +/- 8 nmol.100 ml forearm-1.min-1, EL and HL) and was suppressed in the controls. With Intralipid, forearm glucose uptake decreased during euglycemia but not during hyperglycemia (+3.85 +/- 0.34 vs. +3.34 +/- 0.25 mumol.100 ml forearm-1.min-1, EC vs. EL, P less than 0.02), with comparable changes in whole body glucose uptake. Glucose oxidation and forearm alanine release decreased with Intralipid at both blood glucose levels, with no significant change in the rates of nonoxidative glucose disposal. These observations support the operation of the glucose-fatty acid cycle at physiological plasma NEFA levels at both blood glucose concentrations, but this was associated with a decrease in peripheral insulin sensitivity only during euglycemia.

Different Levels

Eighty Hereford steers were fed diets with different levels of protected tallow. One-half of the steers received all-concentrate diets with 0–20% tallow, and the other half received 50% concentrate and 50% cubed alfalfa hay diets with 0–10% tallow. As the level of protected tallow in the diet increased, daily feed intake declined in both diets, but daily digestible energy (DE) intake declined then increased with the all-concentrate diets but increased then declined with the hay-concentrate diets. Digestible energy required per unit gain was not affected with the all-concentrate diets but increased then declined as the level of protected tallow was increased with the hay-concentrate diets. Carcass measurements were not influenced by the level of protected tallow in the all-concentrate diets. Carcass backfat declined with an increase in level of protected tallow in the hay-concentrate diets. Blood plasma nonesterified fatty acid levels increased as the level of protected tallow in the diet increased. Packed cell volume increased as protected tallow in the diet increased in the steers fed all-concentrate but not in those fed hay-concentrate. Blood glucose level was not affected by level of protected tallow in the diet. Key words: Steers, digestible energy concentration, protected tallow

ABSTRAK   Tujuan penelitian ini adalah untuk mengetahui status gizi sapi perah laktasi didasarkan pada konsentrasi NEFA (nonesterified Asam Lemak), albumin, kalsium, dan fosfor dalam plasma. Tiga puluh dua sapi perah kepala di periode menyusui kedua digunakan untuk up mengambil plasma darah. Uji t dan regresi sama digunakan untuk berbagai penentu dari konsentrasi. Hasil pengamatan yang berarti dan berbagai konsentrasi NEFA 0.17 mEq.L-1 dan 0,11-0,22 mEq.L-1, albumin 2.69 g% dan 2,51-2,87 g%. Kemudian, mean dan berbagai konsentrasi kalsium plasma 9.39 mg% dan 8,90-9,88 mg%, 8.60 dan 8,10-9,10 mg% dari konsentrasi fosfor plasma. Regresi sama berat plasma NEFA (Y) tubuh (X1), produksi susu (X2) adalah Y = 0,163 X1 + 0,215 X2 (R2 = 11,2%, P> 0,05). Regresi sama plasma albumin (Y), berat badan (X1), produksi susu (X2) adalah Y = 0,197 X1 + 0,006 X2 (R2 = 12,3%, P> 0,05). Regresi sama plasma kalsium (Y), berat badan (X1), produksi susu (X2) adalah Y = -0,099 X1 + 0,389 X2 (R2 = 11,9%, P> 0,05), plasma fosfor (Y), berat badan (X1 ), produksi susu (X2) adalah Y = 0.72 X1 + 0,394 X2 (R2 = 19,2%, P> 0,05). Oleh karena itu, cadangan energi (konsentrasi NEFA), kalsium dan fosfor dalam plasma yang paling persyaratan untuk peningkatan produksi susu.   Kata kunci: NEFA, status gizi, laktasi, sapi perah, produksi susu

The objective of this study was to evaluate the effects of partially substituting for conventional forage, Chinese wildrye (CW), with mulberry leaves (ML) on the growth, digestion, ruminal fermentation, blood metabolites, and meat quality of sheep in a 65-day feedlot study. Thirty-two four-month-old male small-tailed Han sheep (25.15 ± 1.03 kg) were randomly assigned to one of four treatments. The dietary treatments consisted of four proportions of ML (0, 8, 24, and 32%) as a substitute for CW (designated as ML0, ML8, ML24, and ML32, respectively). Rumen digesta and blood samples were collected at day 63 of the trial. Carcass traits were assessed after slaughter at the end of performance period. The results from this study revealed no differences in average daily bodyweight gain (ADG), feed conversion ratio (FCR), and final body weight (FBW) among treatments. The apparent digestibility of dry matter (DM), organic matter (OM), and acid detergent fiber (ADF) was higher in the sheep fed with ML than in those fed CW. The ML24 treatment had a higher digestibility of crude protein (CP) and ether extract (EE). There were no differences (p = 0.13) in ruminal pH values among the treatments. However, there was more microbial protein (p < 0.01) in ML24 and ML32 treatments than the ML0 treatment. Ruminal concentrations of acetate and butyrate were significantly different among treatments, although no difference in concentrations of total volatile fatty acid were found. Additionally, no differences were detected for serum parameters except blood urea nitrogen (BUN). No differences were observed for carcass weight (p = 0.62), dressing percentage (p = 0.31) or longissimus dorsi muscle (LM) area (p = 0.94) among treatments. However, intramuscular fat was higher in the ML24 treatment than in the ML0 treatment. (p < 0.01). There were higher pH values of the 24-h longissimus dorsi in the ML24 treatment than in the ML0 treatment. In addition, the saturated fatty acid (SFA) content was lower (p < 0.01) and the monounsaturated fatty acid (MUFA) content higher (p < 0.01) in the ML24 treatment than in the ML0 treatment. In conclusion, the partially substitution of mulberry leaves for Chinese wildrye in the diet of sheep had a beneficial influence on the growth performance, blood metabolites and carcass characteristics. The inclusion of 24% (air dry basis) mulberry leaf hay in the ration of sheep is recommended based on these findings.
