Different Levels

Supplemental fat sources are utilized in rations for dairy cows as a common method to increase the energy density of the diet to support energy demands for milk synthesis in early lactation (Heravi Moussavi et al, 2007). Although dietary fat supplementation increases the energy density of the diet, data on the relationship between the addition of dietary fat and the performance of lactating dairy cows are inconsistent because the impact of dietary fat is influenced by source of fat, method of processing, amount of fat included in the diet and stage of lactation. Canola seed which contains 40% fat is an excellent source of dietary fat high in unsaturated fatty acids and protein for dairy animals. Canola oil contains 51% oleic, 25% linoleic, and 14% linolenic acids. Fish oil (FO) also contains relatively high concentrations of two polyunsaturated fatty acids of the n-3 family: (EPA, C20:5) and (DHA, C22:6). Combination of fish oil with different plant oils has been studied previously but there are few studies which have examined the inclusion of fish oil in combination with canola oil. The aim of the present study, therefore, was to study the effects of different levels of fish oil and canola oil in early lactating Holstein cows.

Effect Of Feeding

There are too many physiological and nutritional factors which can influence lactation performance of early lactation Holstein dairy cows. Supplemental fat sources are utilized in rations for dairy cows as a common method to increase the energy density of the diet, especially in early lactation (Juchem et al., 2007). The fat sources also have a positive effect on milk fatty acid profile. Canola seed which contains 40% fat is an excellent source of dietary fat high in unsaturated fatty acids and protein for dairy animals. Canola oil contains 51% oleic, 25% linoleic, and 14% linolenic acids. Fish oil contains relatively high concentrations fatty acids of the n-3 family. It seems that feeding a blend of different oils will have more positive productive response than individual usage of them. The aim of this study was to evaluate the effect of feeding diets containing fish oil and canola oil starting from transition period on milk production and composition of early lactating Holstein cows.

Backfat Fatty Acid Profile of Crossbred Pigs Fed a Diet Supplemented with Conjugated Linoleic acid or Sunflower OilThe aim of the study was to investigate the impact of feeding pigs with different levels of conjugated linoleic acid (CLA) or sunflower oil (SFO) on the backfat fatty acid profile. The subjects of research were 60 crossbred gilts divided into 6 groups, which were fed different levels of conjugated linoleic acid or sunflower oil (0.5, 1.0 and 2.0%, respectively). All fatteners were kept and fed under standardized conditions. Animals were slaughtered at 95 kg of body weight. Fatty acid profile was determined in samples of backfat from each animal using gas chromatography. The significance of differences between groups was verified by Duncan's test. In the present study, a beneficial effect of adding CLA was that it reduced saturated fatty acids and increased unsaturated fatty acids in the adipose tissue (backfat) of pigs as compared to fatteners receiving SFO. The amount of monounsaturated fatty acids in the backfat decreased with increasing amounts of CLA or SFO. Modifying the fatty acid profile of pig backfat through addition of CLA or SFO would be beneficial to the health of consumers because relatively large amounts of fat pork, including backfat, are added to the sausages.

The effects of grazing lactating cows in mountainous areas for 12 and 24 h compared with the confined indoor system were evaluated by examining the overall milk fatty acid and cortisol. Twenty-one dairy cows were allocated to three treatment groups: (1) control (confined management system in a free-stall barn; TMR based), (2) grazing for 12 h (12hG; TMR plus grazing pasture), and (3) grazing for 24 h (24hG; pasture-based feeding system). Dry matter intake was higher in the control and 12hG groups than in the 24hG group. The yields of total milk and the 3.5% fat-corrected milk were the lowest in the 24hG group. Milk fat was the highest in the 24hG group and higher in 12hG compared with the control group. Milk protein and lactose levels were the highest in the 12hG group. The highest somatic cell count was observed in the 24hG group. The saturated fatty acid levels were higher in the control group compared with the 12hG and 24hG groups. There was no difference in overall mono-unsaturated fatty acids between 12hG and 24hG groups. Poly-unsaturated fatty acids were higher in the 12hG group compared with the control and 24hG groups. There was no difference in omega-6 (ω-6) fatty acids among the groups, and omega-3 fatty acids were higher in the 12hG group than in the control group. Milk cortisol was the highest in the 24hG group and higher in the control group compared with the 12hG group. Taken together, grazing for 12 h is advisable for farms that have access to mountainous areas to improve the milk fatty acid profile and decrease the stress levels in high-yielding Holstein lactating cows.

ABSTRAK      Penelitian ini bertujuan untuk menyelidiki pengaruh dari pemberian pakan yang mengandung mikroenkapsulasi minyak kanola pada konsumsi, kecernaan nutrien, dan performa pertumbuhan pada domba. Lima belas domba garut jantan dengan rataan bobot badan awal 20.17 ± 4.65 kg digunakan dalam rancangan acak kelompok (RAK) pada periode pemeliharaan selama 100 hari dengan 3 perlakuan dan 5 kelompok sebagai ulangan. Perlakuan yang digunakan adalah P0 (kontrol / hijauan: konsentrat = 60:40), P1 (P0 mengandung 4% minyak kanola), dan P2 (P0 mengandung 4% mikroenkapsulasi minyak kanola). Hasil yang diperoleh dalam penelitian ini menunjukkan bahwa tidak ada perbedaan untuk performa, konsumsi dan kecernaan nutrien. Suplementasi minyak kanola murni maupun terenkapsulasi sebagai sumber energi dalam ransum domba, menghasilkan pertambahan bobot badan harian (PBBH) dan efisiensi penggunaan pakan yang terbaik. Proporsi asam lemak tak jenuh pada perlakuan suplementasi mikroenkapsulasi minyak kanola 8% lebih tinggi dibandingkan dengan kontrol. Perlakuan minyak kanola murni meningkatkan (P<0.05) proporsi asam stearat (C18:0) dibandingkan perlakuan lainnya. Sehingga, dapat disimpulkan bahwa suplementasi 4% mikroenkapsulasi minyak kanola di dalam ransum, selaian menghasilkan PBBH dan efisiensi pakan terbaik juga mampu melindungi asam lemak tak jenuh (ALTJ) dari proses biohidrogenasi rumen tanpa mengganggu konsumsi dan kecernaan nutrient ransum.Kata kunci: konsumsi, kecernaan, mikroenkapsulasi, minyak kanola, performaABSTRACTThe aim of this study was to investigate the effects of feeding diets with microencapsulation of canola oil on intake, nutrient apparent digestibility, and growth performance of lambs. Fifteen male garut lambs with an initial average body weight of 20.17 ± 4.65 kg were used in a randomized block design (RBD) for a 100-days feeding period with 3 treatments and 5 groups as replication. The treatments were P0 (control/forage:concentrate = 60:40), P1 (P0 contained 4% of canola oil), and P2 (P0 contained 4% of microencapsulated canola oil). The results showed that there was no difference in the growth performance, intake, and digestibility of nutrients. The best of average daily gain (ADG) and feed efficiency results from the supplementation of pure canola oil or encapsulated canola oil in diets. The proportion of unsaturated fatty acids in the supplementation of microencapsulated canola oil treatment was 8% higher than control. The treatment of canola oil supplementation increased (P<0.05) the proportion of stearic acid (C18:0) compared to other treatments. Thus, it can be concluded that supplementation of 4% of microencapsulated canola oil, besides produced the best of ADG and feed efficiency, was also able to maintain unsaturated fatty acids from the rumen biohydrogenation process without detrimental effects on nutrient intake and digestibility in lambs.    Keywords: canola oil, digestibility, intake, microencapsulation, performance
