Pengaruh Penambahan Mikroenkapsulasi Minyak Kanola Terhadap Performa, Kecernaan Nutrien, dan Profil Asam Lemak Rumen Domba

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.

Diarrhea Incidence

Abstract Antibiotics growth promoting (AGP) in animal feed has been restricted. With this, several additives have been tested in order to replace AGP and ensure intestinal health. The objective of this study was to evaluate the effects of a blend of additives on growth performance, diarrhea incidence and cecal content microbiota of nursery pigs. A total of 576 weaned pigs (6.21 ± 1.16 kg) were assigned into 4 treatments (12 replicates) in randomized block design: basal diet without additives (NC); basal diet with 120 ppm of halquinol (PC); NC + 0,05% blend of lactic acid (3,5%), benzoic acid (2,5%), flavonoids (3,5%) (B5); NC+ 0,1% of same blend (B10). The pigs were weighed 0 and 42 days into the experiment. On day 10, one animal per pen (10 replicates) was euthanized for microbiota analyses. The diarrhea incidence was calculated by the percentage of visual pens with diarrhea, by day, in the period. The growth performance was analyzed by GLIMMIX procedure and the means were compared with Tukey test (P < 0.050) (SAS, 2009). Diarrhea incidence was analyzed by GENMOD procedure (SAS, 2009). The Kruskal Wallis test was used to compare microbial biodiversity (P < 0.050) by statistical program STAMP. The final weight (P = 0.010) and average daily gain (P = 0.001) of B10 and PC were higher than NC. Regarding diarrhea, it was observed that the B5 and B10 had lower incidence when compared to other groups in the total period. In the microbiome analyses, it was observed that the B5, B10, and PC groups had lower (P = 0.021) biodiversity when compared to the NC piglets. However, the B5 and B10 group had higher biodiversity when compared to the PC group. In conclusion, the supplementation with 0,1% blend of additives can be a substitute for AGP.

Abstract Corn hybrids can be selected for improved digestion rates using lab techniques, which should impact animal performance. The objective of this study was to evaluate two Masters Choice corn silage hybrids on growing steer performance. In an 84-day growing study, 288 crossbred steers (initial BW = 303 ± 12 kg) were utilized in a generalized randomized block design with three diet treatments, 12 steers per pen and 8 pen replicates per treatment. Diets consisted of 80% corn silage (DM basis) of Masters Choice hybrid MCT6365 RIB (MC1, that has been selected to improve fiber and starch digestion) and MCT6733 GT3000 (MC2, that has been selected to improve fiber digestion) were compared to a conventional corn hybrid Farm Choice (CON, that is commonly grown in Eastern Nebraska). All corn was grown in one field under identity preserved method and harvested at 37-38% DM in three consecutive days. Relative to CON, feeding MC1 resulted in similar dry matter intake (DMI, P = 0.28), but numerically increased average daily gain (ADG, P = 0.14) which significantly improved feed efficiency (G:F, P = 0.02). Feeding MC2 led to greater DMI (P < 0.01), similar ADG (P = 0.45), and lower G:F (P < 0.01) compared to CON. The results suggest that feeding Masters Choice hybrid MCT6365 RIB (MC1) corn silage at 80% of the diet DM improved ADG and G:F by 4.2%, while feeding MC2 decreased G:F by increasing DMI compared to CON. Differences in corn hybrids exist when feeding growing cattle 80% silage.

Context It is hypothesised that the use of processed soybean for feedlot beef cattle improves feed efficiency and produces beef with a better fatty acid profile for human health. Aims This study aimed to evaluate average daily gain, feed efficiency, carcass traits, chemical composition, fatty acid profile and colour in the beef of young bulls fed diets with ground or extruded soybean. Methods A total of 60 young Zebu bulls (Nellore or Nellore crossed with other Zebu breeds) with an average initial liveweight of 320 ± 8.12 kg and an average initial age of 20 ± 2 months were randomly assigned to receive one of the following diets for 84 days: dehulled and defatted soybean meal (3.22% of ether extract), ground soybean (6.51% of ether extract) or extruded soybean (6.37% of ether extract). The fatty acid profiles of these animals were analysed using high-resolution gas chromatography. The CIE L*a*b* colour space model was used to numerically describe the colour during the aging period (0, 7, 14 and 21 days). Key results Diet had no effect on the average daily gain, feed efficiency or carcass traits of the animals (P > 0.05). Protein, ether extract and ash composition of the Longissimus lumborum (LL) muscle were not affected (P > 0.30) by the use of processed soybean grains. The ground soybean diet decreased oleic acid and C18:2 c9, t11 concentrations, but increased C18:2 t10, c12 and trans-octadecenoic acid isomer concentrations in the LL muscle compared with those in the dehulled and defatted soybean meal and extruded soybean diets (P < 0.05). Muscle from bulls fed processed soybean exhibited greater concentrations of stearic acid and saturated fatty acids, and a lower concentration of unsaturated fatty acids, as well as a decreased unsaturated fatty acids:saturated fatty acids ratio (P < 0.05). Processed soybean grains did not affect (P > 0.05) the LL muscle pH or colour. Conclusions The use of ground or extruded soybean did not affect the performance, carcass traits, LL protein, ether extract or ash composition, and had no impact on beef colour compared with the diet containing soybean meal. Processed whole soybeans in the diet did not increase unsaturated fatty acids or conjugated linoleic acid in beef compared with a diet without soybean meal. Implications Up to 20% of ground or extruded soybean in feedlot beef cattle can be used as a replacement for soybean meal and corn.

High Moisture Corn

Abstract The objective of this study was to evaluate the effect of feeding Aspergillus ssp. blend in combination with dry-rolled (DRC) or high-moisture corn (HMC) based finishing diets on performance and carcass characteristics. Crossbred beef steers (n = 320; initial BW = 267 ± 9 kg) were utilized in a generalized randomized block design. Cattle were assigned randomly to pens by initial body weight (BW) and pens were assigned randomly to one of four treatments with 8 pens per treatment for simple effect means. Treatments were set up as a 2 × 2 factorial arrangement with factors consisting of corn processing and 0 g / steer daily or 10 g / steer daily Aspergillus ssp. blend. There were no significant interactions (P ≥ 0.23) observed between corn processing and Aspergillus ssp. blend in the diet; therefore, only main effects are discussed. For the main effect of Aspergillus ssp. blend; no significant differences were observed for dry-matter intake (DMI), average daily gain (ADG), feed efficiency (G:F), hot carcass weight (HCW), or carcass traits (P ≥ 0.78). Cattle fed Aspergillus ssp. blend had a greater 12th rib fat (P = 0.05). For the main effect of corn processing, cattle fed DRC had heavier HCW and final BW (P = 0.04), greater ADG (P = 0.05), and greater DMI (P < 0.01). However, steers fed HMC had greater G:F (P < 0.01) compared to DRC. These data suggest that feeding Aspergillus ssp. blend in either with dry-rolled or high moisture corn diets did not significantly improve performance or carcass characteristics in finishing beef steers. While feeding HMC improved feed efficiency compared to DRC, feeding DRC increased ADG (and also DMI) compared to HMC.

Abstract The objectives of this trial were to evaluate the effect of corn processing during the finishing phase on feedlot cattle performance and carcass characteristics. We hypothesized that steers fed dry-rolled corn would have better feed efficiency (less feed necessary to the same amount of gain) than steers fed whole shelled corn. Ninety-five backgrounded Angus-cross cattle, (initial body weight (BW) = 263 ± 9.8 kg) were used in a randomized complete block design in a feedlot setting. Cattle were divided in to 3 blocks: heifers (n = 31, 4 pens; initial BW = 267 ± 1.3 kg), light steers (n = 32, 4 pens; initial BW = 253 ± 1.3 kg), and heavy steers (n = 32, 4 pens; initial BW = 279 ± 1.4 kg). Diets contained 70% corn (experimental treatment), 15% dried distiller’s grains with solubles, 7% grass hay, and 8% supplement, on a dry matter basis. Cattle were fed for 217, 224, and 231 ± 8 d for the heifer, heavy steer, and light steer blocks, respectively. Two pens within each block were randomly assigned to one of the following treatments: 1) dry-rolled corn (DRC) or 2) whole shelled corn (WSC). Animal growth performance and carcass characteristics were analyzed using the MIXED procedure of SAS, including the fixed effect of treatment. Pen and block were included as random effects. Carcass characteristics USDA Yield Grade and Quality Grade distributions were compared using the GLIMMIX procedure of using the same model than the growth performance data. Data are presented as LSMeans. Cattle fed DRC had greater average daily gain (ADG; P = 0.02) and final BW (P < 0.01) when compared with cattle fed WSC. Even though ADG was greater for the DRC treatment, feed efficiency was similar (P = 0.45) because dry matter intake (DMI) was also greater (P = 0.04) for DRC when compared with the WSC treatment. Cattle fed DRC also had greater hot carcass weight (P < 0.01), dressing percentage (P < 0.01), and Longissimus dorsi muscle area (LMA; P < 0.01) than cattle fed WSC. No differences (P ≥ 0.18) were observed for marbling score, USDA Yield Grade or USDA Quality Grade. In conclusion, feeding DRC to feedlot cattle improved ADG, hot carcass weight, and LMA, without affecting feed efficiency or meat quality.

Background: Organic acid as a green feed additive is increasingly favoured by enterprises and scholars, but little emphasis has been placed on the effect of organic acids on broiler meat quality. Methods: A total of 192 male chicks (one-day-old, weighted 48.40 ± 0.64 g) were selected to investigate the effect of mixed organic acids (MOA) on growth performance, meat quality as well as fatty acids profile. Chicks were randomly allocated to three treatments with eight replicates and eight chicks per replicate, including a corn–soybean basal diet with 0 (CON), 3000 mg/kg (low MOA; LMOA), and 6000 mg/kg (high MOA; HMOA) MOA. The experiment was divided into starter (d 1–d 21) and grower (d 22–d 42) phases. Results: Broilers supplemented with LMOA and HMOA enhanced (p < 0.05) the final body weight and average daily gain in the grower and overall phases. An improved (p < 0.05) feed conversion ratio in the grower and overall phases was observed in broilers supplemented with LMOA. The breast and thigh muscles pH24h were higher (p < 0.05) in broilers fed with HMOA and the redness in thigh meat was also improved (p < 0.05). Additionally, supplementing LMOA increased (p < 0.05) the saturated fatty acids, unsaturated fatty acids and the ratio of polyunsaturated fatty acids to saturated fatty acids in breast meat. A positive effect occurred (p < 0.05) on jejunal villus height and ileal crypt depth in 21 d broilers supplemented with HMOA. Conclusion: Our findings indicated that dietary supplementation of MOA could improve the growth performance, meat quality, and fatty acids profile, as well as intestinal morphology. Furthermore, diets supplemented with mixed organic acids at 3000 mg/kg may be more desirable, considering the overall experimental results in broilers.

Nursery Pig

Abstract A total of 140 weanling pigs (241 × 600, DNA, Columbus, NE; initially 5.5 ± 0.79 kg body weight) were used in a 32-d study evaluating the effects of increasing dietary Fe from either iron sulfate (FeSO4) or iron carbonate (FeCO3) on nursery pig growth performance and blood Fe status. The pigs used for this trial did not receive an Fe injection after birth in order to increase the sensitivity to added dietary Fe after weaning. Pigs were weaned at approximately 21 d and allotted to pens based on the initial weight in a completely randomized block design with five pigs in each pen and four pens per treatment. Experimental treatments were arranged as a 2 × 3 + 1 factorial with main effects of dietary Fe source (FeSO4 vs. FeCO3) and level (10, 30, or 50 mg/kg of added Fe) plus a negative control with no additional dietary Fe. The basal diet contained 40 mg/kg total dietary Fe based on ingredient contributions and was formulated with an Fe-free trace mineral premix. Experimental diets were formulated below the pigs recommended Fe requirement based on NRC (2012) estimates. Experimental diets were fed in pellet form in a single phase for the duration of the trial. From day 0 to 32, there was no evidence for source × level interactions for growth performance, hemoglobin (Hb), or hematocrit (Hct) values. There was no evidence for a difference (P > 0.10) in dietary Fe source. Providing increasing Fe levels in the diet from either FeSO4 or FeCO3 improved (P < 0.05) average daily gain, average daily feed intake, gain-to-feed ratio, and increased (P < 0.05) Hb and Hct values. A day effect (P = 0.001) was observed for both Hb and Hct with values increasing throughout the study. Increasing dietary Fe levels in the diet from either FeSO4 or FeCO3 increased (linear; P < 0.05) Hb and Hct values on days 14, 21, and 32. In summary, these data suggest that the micronized form of FeCO3 is a source of Fe that can be added to nursery diets to yield similar responses to those observed from FeSO4 supplementation. Similar to previous research, increasing dietary Fe improved the growth performance and increased Hb and Hct values when pigs have low Fe status at weaning.

This research aimed to evaluate the performance of fattened madura cattle fed on coffee husk as a source of fibre to substitute grasses. Twenty Madura steers aged approximately 1.5 to 2.0 years with initial weight of 165-190 kg were divided randomly into four different experimental diets, namely R0= 90% concentrates +0% coffee husk +10% napier grass, R1= 90 % concentrates +3.33% coffee husk +6.67% napier grass, R2 = 90% concentrate +10% 6.67% coffee husk +3.33% napier grass, R3 = 90% concentrates 90% + 10% coffee husk +0% napier grass. The feed was given at 3% body weight of dry mater. The cows were kept in individual pen for two months. Variables measured were dry mater intake, feed efficiency, average daily gain (ADG), digestibility of feed and income over feed cost. Data obtained were analyzed using analysis of variance based on randomized block design followed by Duncan’s multiple range test. Results showed that dry matter intake, ADG, feed efficiency and feed digestibility of cattle on each treatment of the feed were not significantly different (P > 0.05). Average of dry matter intake and daily gain for R0, R1, R2, and R3 were 6.01, 5.84, 5.73 and 5.62 kg/head/day and 0.88, 0.87, 0.84 and 0.93 kg/head/day respectively. While the average of feed efficiency and DM digestibility for R0, R1, R2, and R3 were 14.64, 14.89, 14.65 and 16.54 % and 84.82, 84.37, 83.47 and 83.30 %, respectively. It is concluded that the used of 10% coffee husk as a source of fibre for substitution of napier grass can be used without negative effect on madura’s cattle performances and tend to give higher values of IOFC on fattening program.

Randomized Block Design

Abstract Nutrition for a positive growth path represents the major cost of any beef cattle enterprise. Improvements on feed efficiency (FE) can lead to significant economic benefits and reduce the environmental footprint. Usually, animals selected for FE on high-protein (HP) diets are expected to perform as efficiently on low-protein (LP) diets. This experiment used 30 Bos indicus steers (398 ± 24 kg BW) to determine the agreement between FE rankings of beef cattle fed a LP or a HP diet. As hypothesis, it was suggested that the agreement would be high. A completely randomized block design was used, where each steer represented an experimental unit. Steers were fed in individual pens for two periods of 70 days, including an adaptation of 10 days, with diets supplying either 70% or 100% of their rumen degradable protein requirements. Average daily gain (ADG) and dry matter intake (DMI) were measured, while residual feed intake (RFI) and residual gain (RG) were calculated. Kappa analysis was used to determine the agreement between FE of both diets. In the LP diet, ADG was 0.93 kg/d (0.38 to 1.47), DMI averaged 9.67 kg/d (7.9 to 12.1), RFI varied between -1.55 and 1.84, and RG from -0.61 to 0.53. In the HP diet, ADG was 1.16 kg/d (0.77 to 1.57) and DMI averaged 9.87 kg/d (4.79 to 11.87). RFI varied between -2.53 and 1.61 and RG from -0.34 to 0.33. Chance-corrected analysis of the ranking between diets showed no agreement for RFI (Kappa=5.6%, P = 0.68) nor for RG (Kappa=9.1%, P = 0.44). These results suggest that different physiological mechanisms are responsible for FE regulation in both diets; thus, appropriate diets targeting each scenario must be used when selecting animals for feed efficiency.

This study aimed to analyze nutrient digestibility of a combination of various protein sources (coconut meal, fish meal and soybean meal) in the concentrate of local rams fed corn cob based diet. Twelve local rams (26.6 ± 1.5 kg BW) fed corn cob based feed were used in this study using in a randomized block design with 4 treatments and 3 replicates. The treatments used were combination of different protein sources namely R1 = combination of coconut and urea cake, R2 = combination of coconut cake and soybean meal, R3 = combination of coconut cake and fish meal, and R4 = combination of coconut, soybean, and fish meal. Data were analyzed by ANOVA and significant differences between treatments were tested by the Duncan Multiple Range Test. The results showed that the combination of various protein sources did not significantly influence the consumption of dry matter and crude fiber, but the used of protein sources of coconut cake and soybean meal significantly increased (p<0.05) intake of organic matter and crude protein. The combination of coconut meal and fish meal (R3) or a combination of coconut cake and soybean meal (R2) increased (p<0.05) nutrient digestibility. Different protein sources do not affect average daily gain (ADG) and feed efficiency . It can be concluded that the use of corn cobs based diet with protein sources combination of coconut meal and fish meal or a combination of coconut cake and soybean meal can increase nutrient digestibility but has not significantly improved body weight and feed efficiency.
