Konsumsi Zat Makanan, Profil dan Metabolit Darah Induk Domba dengan Ransum Kaya Lemak Asal Minyak Nabati: Nutritional Intake, Blood Profile and Metabolites in Ewes Fed a Fat-Rich Diet of Vegetable Oils

The aimed of this study was to evaluate the effect of vegetable fat supplementation in diet upon nutritional intake, the blood profile and metabolite of Garut ewes. Ten ewes with an initial weight of 24.87 ± 4.02 kg were used in this experiment.&nbsp; The feed composition and ingredients used were based on the feed commonly used by Garut sheep breeders.&nbsp; The Sunflower seed oil and canola oil were used as source of vegetables oils.&nbsp; The feeding treatments were R0 (control = without the addition of vegetable oils) and R1 (the ration contains 5% vegetable oil).&nbsp; The data obtained were analyzed by T-Test.&nbsp; Nutrient intakes, including dry matter (DM), Crude Protein (CP), Crude Fat (CF), Crude Fiber (CF) and Nitrogen-Free Extract (NFE) were similar between dietary treatment of 5% vegetable oils supplementation and control. While Fat consumption was significantly higher (p&lt;0.01) in vegetable oil supplemented group (R1) compare to control. The results of blood metabolites, including glucose and cholesterol and blood profile (hematocrit, hemoglobin, leukocytes, erythrocytes) analysis indicate that vegetable oil supplementation can be done without any significant effect. It was concluded that the ration containing 5 percent vegetable oil was not interfere the nutrients consumption, blood profile and metabolite levels of the postpartum ewes, so it can be applied by farmers

Effect of Sunflower Oil Supplementation as Unsaturated Fatty Acid Source on Rumen Fermentability and Performance of Lactating Garut Ewes

The study was aimed to evaluate the increasing levels of ration energy, with fat-rich unsaturated fatty acids from sunflower oil on the nutrient intake, rumen fermentability and performance of ewes. The experiment used fifteen ewes of 1.5 years old, primiparous, caged individually with their lambs and conducted three treatments and five replications from a completely randomized designed. Those treatments included R1= ration with 0% sunflower oil addition, R2= ration with 4%sunflower oil addition, R3= ration with 6% sunflower oil addition. The variables consisted of dry matter intake, nutrients, ewes performances (birth weight, weaning weight, decreased of body weight), total and partial VFA, the ratio of acetate: propionate, methane production, protozoa and bacterial population. Data were analyzed statistically and descriptively. The results showed that the treatments did not influence dry matter intake and nutrients,. rumen fermentability and ewes performances. Although the treatments increased (P<0.01) fatconsumption and reduced shrinkage of body weight. It can be concluded that the adding sunflower oil as the resource of unsaturated fatty acids up to 6% of the ration was not negatively affected the fermentability of rumen, moreover can improve ewes body condition and, accelerated body weight recover

Fermentation Characteristics and Nitrogen Retention of Madura Cattle Fed Complete Rations Containing Soybean Pod and By-Products

This study was aimed to evaluate the effect of complete rations containing soybean pod and soybean by-products (soybean meal and tofu waste) on rumen microbial population, fermentation characteristics, nutrient digestibility, and nitrogen retention of Madura cattle. Twelve Madura cattle of 1.5 years of age were given 4 feeding treatments in triplicates in randomized block design experiment. The treatments included T0 (100% native grass) as a negative control, T1 (concentrate: grass (60:40) as a positive control, T2 (complete ration containing 15% soybean pods), and T3 (complete ration containing 30% soybean pods). The treatments were based on feeding practices commonly applied by farmers in the village. The results showed that the use of concentrate rations or complete rations containing soybean pod and by-product did not affect protozoa population, ammonia concentration, and total VFA production compared to cattle fed 100% native grass. In contrast, the use of concentrate rations or complete rations containing soybean pod and by-products reduced acetate and increased butyrate proportion compared to native grass. The use of a concentrate ration resulted the highest propionate proportion. Methane estimation increased with the use of concentrate ration or complete ration containing 15% soybean pod, but it decreased when the level of soybean pod was increased to 30%. It can be concluded that soybean pod has a potential to be used as a fiber source in beef cattle ration to substitute native grass
