The objective of this study was to examine the effect of different levels of rumen undegraded protein (RUP) in diets of lactating dairy cows on feed intake and nutrient digestion. The experiment was run according to completely randomized design with three treatments of complete feed rations containing different levels of rumen undegraded protein (RUP) and four replications for each treatment. In a digestibility trial, twelve Friesian Holstein cows were divided into three groups at each group consist of four cows and given three dietary treatments containing three levels of RUP, namely 7.43% of total crude protein /CP (P0), 8.49% of total CP (P1), and 9.45% of total CP (P2). Diets consisted of forages (King grass, Pennisetum hybrid) and concentrates at ratio of 50:50 in dry matter basis. The diets contained 18.25% CP and 61.75% total digestible nutrient (TDN). The cows fed diet (P0) were considered the control group. Drinking water was given ad libitum. This experiment was conducted for 21 days of adaptation period and seven days of collection period. In the collection period, samples of feed, refusal feed, and faecal were collected to get the chemical content includes dry matter (DM), organic matter (OM), ether extract (EE), crude fiber (CF), crude protein (CP), nitrogen-free extract (NFE) and total digestible nutrients (TDN). The data obtained were processed with one-way ANOVA (analysis of variance) and the difference existed between the means (P<0.05) would be analyzed with Duncan’s new multiple range test. The results showed that cows fed diet P2 (9.45% RUP in CP) in had significantly higher feed and nutrient intake (DM, OM, CP, CF, EE, TDN) and higher DM and OM digestibility compared to the other two treatments.

This experiment aimed to determine the nutrient digestibility of Bligon and Kejobong goats fed by king grass and peanut straw. The sample used was 6 to 8 months of five male Bligon goats, and five male Kejobong goats with the initial body weight of 15 to 20 kg and placed in separated metabolism cages. The diet and water were supplied ad libitum. This experiment was done in 14 days of adaptation period and seven days of the collection period. In the collection period, samples of feed, refusal feed, and feces were collected to get the chemical content includes dry matter (DM), organic matter (OM), ether extract (EE), crude fiber (CF), crude protein (CP), nitrogen-free extract (NFE), and total digestible nutrient (TDN). The data obtained were subjected to a T-test analysis. Results showed that nutrients intake, digested nutrient as well as nutrient digestibility of Bligon and Kejobong goats were not significantly different. However, Kejobong goats had EE and CP intake of 15.42% and 14.02%, digested DM, OM, and NFE of 16.29%, 15.71%, and 13.93% respectively, as well as NFE digestibility 4.37% higher than those Bligon goats (P< 0.05). Therefore, there was no difference in nutrient intake, digested, and digestibility of nutrients in Bligon and Kejobong goats fed by king grass and peanut straw. However, Kejobong goats appeared to have higher EE and CP intake, as well as digested and digestibility of DM, OM, and NFE than Bligon goats.

Chromic oxide (Cr2O3) in paper pellets was used as an indicator for digestibility studies with four Holstein-Friesian cows fed rations composed of different roughage to concentrate ratios. Cows A and B received one pellet, or 3.46 g of Cr2O3, whereas cows C and D received three pellets, or 10.38 g of Cr2O3, daily.Recovery of Cr2O3 in the feces varied from 84 to 103% for animals A and B and from 92 to 95% for animals C and D. The coefficients of apparent digestion of dry matter were lower (P < 0.01) when the Cr2O3 method was used instead of the conventional method. When samples were taken at 0500, 0900, 1300 and 1700 hours, the Cr2O3 method gave average estimates of digestibility for animal pairs A, B and C, D that were 94.2 and 97.5% of those obtained by the conventional method. Standard deviations for both the Cr2O3 and conventional methods were relatively high.Excretion patterns of Cr2O3 were not signicantly correlated with those of crude protein, phosphorus and calcium. The average concentrations of crude protein, phosphorus and calcium in compounded feces samples collected at 0500, 0900, 1300 and 1700 hours were 101.3, 100.6 and 96.7% of those in samples of the total excretions.The daily administration of 10.38 g of Cr2O3 at 0900 hours for eight days, and the collection of fecal grab samples at 0500, 0900, 1300 and 1700 hours daily during the last five days seemed satisfactory for estimating apparent digestibility of dry matter.

(Improvement of fermented bagasse quality as animal feed by fermentation through administration of sago flour at different levels)ABSTRACT. Feed plays an important role in livestock production system. Due to limitation of pasture and forege areas, it needs to find new feed alternative as replacement of forage as animal feed. One of feed alternatives as replacement of forage is bagasse. Bagasse has low nutritive content and digestibility. One of the efforts to improve bagasse quality is by fermentation. The purpose of this experiment was to improve nutritive values of bagasse by fermentation method by using Trichoderma harzianum as inoculum. This research was conducted at Animal Nutrition Laboratory, Animal Husbandry Department, Agricultural Faculty, Syiah Kuala University, Banda Aceh from January to April 2015. The experiment was designed by completely randomized design (CRD) with 4 treatments (addition of sago flour at defferent levels); R1 control (0% sago flour), R2 (5% sago flour), R3 (10% sago flour), R4 (15% sago flour) of fermented material. Each treatment has 4 replications, therefore there were 16 units of treatment. Parameters observed in this experiment were nutritive values of fermented bagasse including the contents of dry matter, crude protein, crude fiber and ash. The results of the experiments indicated that fermented bagasse with Trichoderma harzianum by addition of various levels of sago flour had significantly effect (P0, 05) on crude fiber and ash contents. However, there were not significantly difference (P0, 05) on dry matter and crude protein contents. In conclusion, addition of various levels of sago flour by using Trichoderma harzianum at fermented bagasse was able to improve nutritive values of fermented bagasse.

The study compared the influence of chitosan sources on rumen fermentation, methane emission and milk production in lactating dairy cows fed a glycerin-based diet. Six, lactating Holstein-Frisian crossbreeds (410 &plusmn; 5.0 kg BW, 120 &plusmn; 21 day-in-milk), were arranged in a 3 x 3 replicated Latin square design. In addition to control, a 2% chitosan extract supplement and a 2% commercial chitosan supplement of dry matter intake were the treatments. The results denoted that no significant differences on daily dry matter, nutrients or estimated energy intake were noted when cows received different sources of chitosan. Nutrient digestibility was not influenced differently by extraction based or commercial chitosan supplements. The pH, temperature, ammonia nitrogen, blood urea and microbial count were similar among treatments. The different sources of chitosan supplements did not change the totals of volatile fatty acids, acetate and butyrate; in contrast, different chitosan sources influenced (P&lt;0.05) propionate content. The ruminal acetate to propionate ratio was markedly (P&lt;0.05) reduced with chitosan supplement, but no change appeared between sources of chitosan. At 4 hours after feeding, the methane estimation significantly decreased with the addition of chitosan supplementation (P&lt;0.05) compared to the control group. The purine derivatives and microbial protein synthesis were not altered by the treatments. No significant differences existed on milk yield, milk composition or milk urea nitrogen when cows received different sources of chitosan (P&gt;0.05). In sum, supplementing extracted chitosan showed more potential than did commercial chitosan for enhancing economic efficiency and recycling shrimp residues, therefore, reducing environmental waste.

The intake of dry matter from a pasture of Pangola grass by lactating dairy cows was measured. The chromic oxide administration technique was used. It was shown that the intake of dry matter was significantly higher in the dry season than in the wet. Reasons for this were discussed. An assessment of the nutrient intake of the animals was made and it was concluded that if the requirements of cattle in temperate climates was taken as a guide, this was adequate for at least maintenance and production of 1½ gal. per day of milk in the wet season. Under dry season conditions the intake of total digestible nutrients was adequate for the same level of production, but the digestible protein level was considerably below requirement. It was therefore concluded that supplementation with protein concentrates in the wet season was unnecessary save for high-yielding cows, but that all cows required concentrates during the dry season conditions of the experiment.

Flaxseed hull, a co-product obtained from flax processing, is a rich source of n−3 fatty acids but there is little information on digestibility of its nutrients by dairy cows. Four rumen-cannulated multiparous Holstein cows averaging 665±21 kg of body weight and 190±5 d in milk at the beginning of the experiment were assigned to a 4×4 Latin square design with four 28-d experimental periods to determine the effects of feeding monensin and flaxseed hulls on total tract apparent digestibility of nutrients and fatty acids. The four treatments were: (1) diet CO: control with neither flaxseed hulls nor monensin added; (2) diet FH containing 19·8 g flaxseed hulls/100 g dry matter (DM); (3) diet MO with 16 mg monensin/kg DM; (4) diet HM containing 19·8 g flaxseed hulls/100 g DM and 16 mg monensin/kg DM. Diets provided similar amounts of protein and net energy of lactation. Digestibility of crude protein was higher for diets containing flaxseed hulls and for diets supplemented with monensin. Flaxseed hulls supplementation decreased digestibility of acid and neutral detergent fibre. Significantly higher digestibility of ether extract and individual fatty acids was observed for treatments with flaxseed hulls compared with treatments without flaxseed hulls. A combination of flaxseed hulls and monensin did not result in better fatty acid digestibility than when feeding only flaxseed hulls.

Industrialization of the Babassu coconut for edible oil production generates many co-products and has great potential to be used in ruminant nutrition. The aim of this study was to evaluate the effect of different inclusions of endocarp meal type II of Babassu coconut (BEMII) on intake and digestibility of sheep diets. Twenty non-castrated male sheep with an undefined breed were distributed in a completely randomized design with four treatments and five replications. The animals received an experimental diet with increasing inclusions of BEMII (0.0%, 7.5%, 15.0%, and 22.5%). Increasing additions of the coproduct negatively influenced dry matter intake (g/BW and g/kg0.75). Crude protein intake (in grams) per day decreased linearly with the inclusion of BEMII, presenting a reduction of 49.35 g/d. The inclusion of 7.5% showed the best response for energy balance among all inclusions and presented the closest nitrogen balance value when compared to the control group; therefore, this inclusion percentage is the best for endocarp meal utilization.

ABSTRACT This study aimed to assess the effects of yellow grease supplementation on the intake, digestibility, and nitrogen balance in sheep. Twenty Santa Inês lambs with a mean age of 95 ± 10 d and body weight of 19.29 ± 3.17kg were evaluated in a completely randomized design. The diets were supplemented with oil at concentrations of 0, 20, 40, 60, and 80 gkg-1 of dry matter (DM) of the concentrate. The diets were based on roughage and concentrate (50:50). The experimental period lasted 19 d and included 14 adaptation days and five collection days for the total supplied diet, orts, feces, and urine. Supplementation with yellow grease had no significant effect on the intake of DM, crude protein (CP), neutral detergent fiber (NDF), or non-fiber carbohydrates (NFC). However, the ether extract (EE) intake increased linearly with supplementation of yellow grease. Moreover, no effect was observed for DM, CP, NDF, and NFC digestibility and nitrogen balance. EE digestibility increased linearly with the yellow grease dietary supplementation. Thus, sheep dietary supplementation with yellow grease may be used at a level of up to 80 gkg-1 of DM of concentrate without impairing nutrient intake and digestibility.

ABSTRACT. Fermentation of rice straw incriased its nutritive value, digestibility and palatability. The aim of the present experiment was to study the effect of feeding rations composed of fermented rice straw supplement with urea and probiotic, and mixed with concentrate. Eighteen Etawah -grade bucks (age 1.5 years) were assigned into a completely randomized design to study nutrient intake and apparent degestibility of three dietary treatments. The rations as treatments were as follow: CFR=concentrate + chopped fermented rice straw:; Complete=concentrate + groud fermented rice straw; ELG = concentrate + elephan grass. Dry matter (DM) and crude protein (CP) intake of bucks were not different significantly among treatments. Apparent degestibility of DM was not different, however CP was significantly lower (p0.05) for the GFR treatments compared to the other two treatments. These results suggest that fermented rice straw can be uded to substituse the fresh elephant grass.

Stem and stump of bananas have potential to be used as an alternative for ruminant feed. However, one of the problem is its rapidly decomposing which affect high of water content. The alternative way to solve this matter by using silage. The aim of this study was to determine the nutritional quality of banana waste silage (stems and stump) with the addition of molasses with different levels. The experimental design was a Completely Randomized Design in factorial 3 × 3 with two replications. The first factor (A) was the composition of the substrate, A1: stump 100% + stem 0%, A2: stump 50% + stem 50%, and A3: stump 0% + stem 100%, while the second factor (B) was the levels of molasses (0; 2.5; and 5%). The parameters measured were dry matter, crude protein, crude fiber, extract ether, ash and BETN. The results showed that the composition of the substrate has significant effect (P<0.05) increased content of dry matter, crude protein, crude fiber, BETN, but did not significant (P>0.05) on extract ether and ash content. There was an interaction (P<0.05) between the substrate composition and the addition of molasses on the content of the ash. The best composition for increasing the nutrient content was stump 100% + stemps 0%. It is conclude that the compostion of stump and stemps may affect the nutrient quality of silage.
