The objective of this study was to compare the effects of two ionophores, lasalocid and monensin (24 mg kg-1 dry matter), on in situ biohydrogenation of C18:2 and C18:3 from whole sunflower seed and flaxseed, respectively. There were no treatment effects on biohydrogenation of C18:2. Ionophore supplementation did not affect the lag time, but monensin decreased the rate of biohydrogenation of C18:3 compared with control and lasalocid.

The objective was to get beef that contain unsaturated fatty acids (especially omega 3 and 6), so as to improve intelligence, physical health for those who consume. The study design using CRD with 3 treatments, each treatment used 4 Bali cattle aged approximately 1.5 years. Observations were made 8 weeks. Pasta mixed with ginger provided konsentrat. P1 (control); P2 (6% saponification lemuru fish oil, olive oil 1%; rice bran: 37.30%; corn: 62.70%; KLK: 7%, ginger paste: 100 g); P3 (lemuru fish oil saponification 8%, 2% olive oil; rice bran; 37.30; corn: 62.70%; KLK: 7%, ginger paste: 200 g). Konsentrat given in the morning as much as 1% of the weight of the cattle based on dry matter, while the grass given a minimum of 10% of the weight of livestock observation variables include: fatty acid composition of meat. Data the analyzies qualitative. The results of the study showed that the composition of saturated fatty acids in meat decreased and an increase in unsaturated fatty acids, namely linoleic acid (omega 6) and linolenic acid (omega 3), and deikosapenta deikosaheksa acid.Keywords :

The effect of adding 5% calcium lignosulfonate (LSO3) and heat to canola screenings on in situ ruminal and intestinal dry matter (DM) and crude protein (CP) disappearance in Holstein cows was investigated. Treatments consisted of untreated canola screenings, canola screenings that had been heated to 100 °C for 30 or 60 min and canola screenings that had 5% (wt wt−1) LSO3 added and were subsequently heated at 100 °C for 0, 30 or 60 min. Results indicate that treatment of canola screenings with 5% LSO3 and heated to 100 °C for 60 min was effective in reducing rumen degradation of DM and CP with a corresponding increase in disappearance in the lower gastrointestinal tract when compared to untreated and heat-treated canola screenings.

Tall fescue (TF) and orchardgrass (OG) were fertilized with 0, 294 or 882 kg NH4NO3/ha and 0 or 833 kg K2SO4/ha to determine the effect on rates of apparent ruminal disappearance of herbage dry matter (DM), nitrogen (N) and sulfur (S) using the in situ nylon bag technique. Losses of water-soluble and filtrable DM, N and S differed significantly due to herbage species, NH4NO3 and K2SO4 fertilization levels. After 24-h ruminal incubation, there was no difference between herbages in residual DM, N or S expressed as a proportion of original nutrient. Increasing level of NH4NO3 fertilization reduced (P < 0.001) 24-h residual DM and N and increased (P < 0.001) residual S. Potassium sulfate fertilization reduced (P < 0.001) residual herbage S after 24-h incubation. Rates of insoluble herbage DM and N disappearance (kd) did not differ between herbages but increasing level of NH4NO3 fertilization increased (P < 0.001) insoluble DM and N disappearance rates. Rate of insoluble S disappearance was lower (P < 0.05) for TF than OG but unaffected by fertilization. Effective ruminal degradability (ERD) of DM (P < 0.01) and release (ERR) of N (P < 0.001) and S (P < 0.05) were lower for OG than TF. Increasing NH4NO3 fertilization increased (P < 0.001) ERD and ERR of DM and N, respectively. Furthermore, NH4NO3 fertilization reduced (P < 0.001) while K2SO4 application increased (P < 0.001) ERR of herbage S. Simple correlation coefficients between kd of DM, N and S and original herbage total N concentration were r = 0.59 (P < 0.001), r = 0.51 (P < 0.001) and r = 0.36 (P < 0.05), respectively. The relationships between ERR of herbage S and total N or nonprotein S concentration in herbage were r = −0.74 (P < 0.001) and r = 0.70 (P < 0.001), respectively.

During our research we studied the fat content and fatty acid composition during the germination and sprouting periods of the most important sprouts: wheat, lentil, alfalfa, radish and sunflower seed. In this article we present our research results during this sprouting study. The concentration of the saturated fatty acids (palmitic acid, stearic acid) decreased, the concentration of the unsaturated fatty acids increased during germination, but the tendency was not so high than was published in the literature.

Ruminal Degradability

High-moisture barley (HMB) was ensiled in polyethylene silage bags. Treatments applied to 30% moisture HMB as a percentage of dry matter (DM) were: none, 1% ammonia, 2% ammonia, and 1.5% sulphur dioxide. A fifth treatment was the addition of 1.5% sulphur dioxide to 20% moisture HMB. Barley samples were ruminally incubated to estimate degradability of DM and nitrogen (N). Ruminally incubated bags were also introduced to the duodenal cannulae and collected in feces to estimate true whole-tract digestion. Sulphur dioxide treatment, or moisture content, had no influence on ruminal degradability, with the exception of increased degradation rate of potentially degradable N for 20 vs 30% HMB, or whole-tract true digestion. Ammoniation resulted in net reduction in rate of ruminal DM release due to shift of soluble DM to the potentially degradable fraction, and decrease in the potentially degradable fraction degradation rate. Ammoniation increased barley N content up to 44% with no change in rate of ruminal N release. Whole-tract true DM digestion was higher for ammoniated barley but N digestion was not influenced. Sulphur dioxide appears to offer no advantages beyond grain preservation, whereas ammoniation offers potential by reducting rate of ruminal DM release, and providing a source of slow release nonprotein N, without affecting post-ruminal digestibility. Key words: High-moisture barley, ammonia, sulphur dioxide

Dairy cows fitted with ruminal, duodenal and ileal cannulas were utilized to investigate the effects of feeding with Ca soaps (CaS) of palm fatty acids (FA) and rapeseed FA. Diets compared were control diet based on maize silage and concentrate, and two diets with 40 g CaS of palm oil FA or rapeseed oil FA/kg diet, replacing part of the concentrates of the control diet. Total digestibilities of dry matter, fibre and fat, and ruminal fermentation were not significantly altered by giving CaS; the extent of ruminal biohydrogenation of total unsaturated C18 FA was significantly reduced by both CaS diets. Apparent intestinal digestibility of FA was not different among diets, although the amount of FA absorbed with the CaS diets was twice that with the control diet. No difference among diets was observed for milk production, or fat and protein contents. Giving CaS diets decreased the proportions of 4[ratio ]0 to 14[ratio ]0 FA in milk fat, and increased cis-18[ratio ]1n−9, compared with control diet. The rapeseed diet lowered the content of 16[ratio ]0, and increased the contents of 18[ratio ]0 and trans-18[ratio ]1n−7. CaS diets did not result in a marked increase of polyunsaturated FA content in milk fat. Butter from cows fed on the CaS diets contained more liquid fat at 6 and 14°C than butter from the cows fed on the control diet. Incorporating CaS, particularly those from rapeseed, in dairy cows' diets increased C18 FA in milk and improved butter spreadability.

This study deals with physical and chemical characteristics and some nutritional properties of the fatty oil extracted from Piper nigrum Linn. (Black Pepper). The seeds of Black Pepper contained fatty acids 12.02% of which the saturated and unsaturated fatty acids contributed 68.71% and 31.29%, respectively. The fatty acids identified by GLC are lauric acid (26.93%), myristic (8.26%), palmitoleic (13.47%), palmitic (12.24%), oleic (17.82%), stearic (17.28%) and lignoceric acid (4.00%). The specific gravity and refractive index were recorded as 0.924 at 30°C and 1.461 at 26°C, respectively. The saponification value, iodine value, peroxide value, acid value and percentage of unsaponifiable matter were found to be 177.92, 15.86, 472.97, 8.27 and 43.28, respectively. The moisture content (2.17%), dry matter (97.83%), ash (12.49%), nitrogen (1.85), protein (11.56%), carbohydrate (45.16%), crude fiber (16.66%) and food energy (335.06 g cal-1) showed that Black pepper seeds are good source of dietary fiber.
