Abstract

The research was intended to know the effect of high quality feed supplement (HQFS) in the ration of first lactation dairy cow on nutrient consumption and digestibility. Twelve dairy cows of Friesian Holstein crossbred fromthe Cooperative of Warga Mulya, Sleman. They were divided into three groups of treatment, namely control (K), substitution treatment (S), and supplementation treatment (A). Each treatment consisted of four cows. Group K fed concentrate only from Warga Mulya, while group S beside concentrate from Warga Mulya, amount of HQFS 300 gram/liter of milk produced was offered, and concentrate was reduced as much as the additional feed of HQFS. Group A was offered by concentrate Warga Mulya plus HQFS additionally for 300 gram/liter of milk per day. Water was provided ad libitum. The variable measured consisted of the feed consumption and digestion (dry matter (BK), crude protein (PK), total digestible nutrient (TDN), organic component (BO), crude fiber (SK), crude fat (LK), and nitrogen-free extract (BETN)). The variants of collected data were analyzed, using Completely Randomized Design one way classification. Results showed that there were significant difference (P<0.05) on BK, PK, TDN, BO, PK, SK, LK, and BETN consumption, while the digestion of BK, BO, SK, and LK did not indicate any differences. The digestion of PK and BETN were significantly different (P<0.05), i.e. A (66.09%), S (59.77%), and K (54.66%) on PK and A (75.30%), S(73.11%), and K (70.69%) on BETN. The conclusion was that the addition of HQFS of first lactation dairy cow would increase nutrient consumption and crude protein and nitrogen-free extract digestibility.(Key words: High quality feed supplement, Dairy cow, Consumption, Digestibility)

Abstract

This study was aimed to observe the growth performance and carcass production of male Rex rabbits fed with corn oil supplementation. Twenty four head of rabbits with 1.362±260 g initial body weight were randomly divided into four groups e.g. R0 (control), R1 (supplemented with 2% of corn oil supplementation), R2 (supplemented with 4% of corn oil supplementation), and R3 (supplemented with 6% of corn oil supplementation). Feed and water were offered ad libitum. The animals were raised for 56 days prior to slaughtering. The collected data was analyzed using one way analysis of variance and followed with least significant different analysis. Dry matter (DM), crude protein (CP), crude fiber (CF), and total digestible nutrient (TDN) intake of R3 was lower (P<0.05) than R0, R1, and R2. There were no significant differences among groups in average daily gain, feed convertion ratio, carcass percentage and meat bone ratio. It is concluded that supplementation of corn oil in the diet had no effect on growth performance and carcass production of Rex rabbits.

Abstract

   The aim of this research was to examine the microbiological quality of calf starter pellet added with fermented cabbage waste after stored for 0, 4, and 6 weeks. The materials used in this research consisted of cornmeal, rice bran, soybean meal, molasses, mineral mix, and fermented cabbage waste. This research used Completely Randomized Design with 4 treatments and 3 replications. The mixed calf starter pellet consisted of 100% calf starter and 6% of fermented cabbage waste, and then stored for 0 weeks (P0), 2 weeks (P1), 4 weeks (P2) and 6 weeks (P3). The observed microbial qualities were the total lactic acid bacteria and the presence of gram positive and negative bacteria in the mixed calf starters. The total lactic acid bacteria were analyzed descriptively, while the presence of gram bacteria was analyzed with analysis of variance followed with Duncan’s test. The result of this research showed that an increase in storage time would result in lower lactic acid bacteria population, while the gram-positive and negative bacteria was not significantly affected. The research concluded that 6-weeks stored calf starter pellet added with 6% of fermented cabbage waste could maintain its lactic acid and gram-positive bacteria population, while also reducing its gram-negative bacteria population as well.

Abstract

This experiment was aimed to study the effect of nutmeg leaf tannin addition on in vitro nutrient digestibility. Treatments in this experiment consisted of: P0 (control without tannin), P1 (feed + 2% tannin) and P2 (feed + 4% tannin). Feed for fermentation substrate consisted of Pennisetum purpureum and soybean meal with ratio 60:40. Fermentation was carried out using Tilley and Terry two stages in vitro technique for 48 hours. Variables measured were the digestibility of dry matter, organic matter, and crude protein in the rumen as well as the total digestive tract digestibility based on in vitro technique. The data obtained were analyzed by One Way ANOVA, and followed by the Duncan Multiple Range Test (DMRT). The results showed that rumen dry matter digestibility was lower (P<0.05) in P1 and P2 (59.03±3.24 and 57.19±1.32) compared to P0 (70.77±1.05), but did not show a significant difference (P>0.05) in the total dry matter digestibility of P0, P1, and P2 (74.88±5.28, 67.70±3.21, and 64.83±4.96). Organic matter digestibility in the rumen was also lower (P<0.05) in P1 and P2 (55.55±6.29 and 55.76±6.88) compared to P0 (75.39±0.91), but did not show significant difference (P>0.05) in total organic matter digestibility from P0, P1, and P2 (64.69±6.44, 64.33±6.34, and 61.20±5.11). The digestibility of crude protein in the rumen at P1 and P2 (45.48±5.12 and 38.47±3.44) was also significantly lower (P<0.05) compared to P0 (60.93±9.72), whereas total digestibility did not show any significant difference (P>0.05). Addition of tannin leaf nutmeg 2% optimally reduced rumen dry matter and crude protein digestibility without causing excessive negative impact on results of in vitro digestibility, so it can be used as a protective agent protein feed.

Abstract

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.

Abstract

This research was carried out to examine the chicory forage yields on different regrowth which were intercropped with Pennisetum purpureum cv. Mott (dwarf elephant grass) on different regrowth due to various harvest age. The research was conducted in the Laboratory of Forage and Pasture, Faculty of Animal Science UGM for 7 months, with a split-plot design and analyzed by Duncan with a total of 9 plots and an area of 2.5x2.5 m2 for each plot. The main plot was the harvest age treatment (30, 45, and 60 days) and the subplot was the regrowth (first and second). In the first stage, as many as 9 cuttings of dwarf elephant grass in one plot were planted with a spacing of 1x1 m2 until the plant height reaches 10 to 15 cm, then the chicory seeds were spread among the dwarf elephant grass plants with the sand mixture. The results showed the harvest age had a significant effect (P<0.05) on chicory's plant height, fresh forage yield, dry matter content, dry matter digestibility, and organic matter digestibility. The 30 to 45 days harvest age performed a higher fresh production more than the 45 days to 60 days harvest age. The 60 days harvest age and second regrowth yielded the highest mixed fresh production compared to the other harvest ages, namely from 12.50 ton/ha to 25.26 ton/ha. Based on the research results showed that the older the harvest age (60 days) increased the biomass of plant production but decreased the plant digestibility. The second regrowth was able to produce higher than the first regrowth, but there was no significant effect on the dry matter content and forage digestibility.

Abstract

 The purpose of this study was to determine the effect of gamma-ray irradiation on Sorghum sudanense in the first offspring (F1) on plant growth, production, and lignin content at different harvest ages. This study used a split-plot design in which varieties of Sorghum sudanense with gamma irradiation and Sorghum sudanense without gamma irradiation are the main plot. Meanwhile, the harvest age is the subplot. The planting area was 1.5x1.5 m, each with 3 replications. The materials used were Sorghum sudanense without gamma-ray irradiation and the first generation seeds (F1) of Sorghum sudanense with gamma irradiation. The method used was irradiating Sorghum sudanense seeds with gamma-ray with a dose of 300 Gy, planting, maintenance, and harvesting. The harvest ages were 50, 70, and 90 days. The data observed were plant growth, namely plant height and length, dry matter (DM) and organic matter (OM) production, and lignin content. Sorghum sudanense with gamma irradiation had higher plant height, plant length, also DM, and OM production (P<0.05) than Sorghum sudanense without gamma irradiation. The lignin content of Sorghum sudanense with gamma irradiation was lower (P<0.05) than Sorghum sudanense without gamma irradiation. Longer harvest age increased (P<0.05) plant height, plant length, production, and lignin content. In conclusion, there were characteristics differences between Sorghum sudanense with gamma irradiation and without gamma irradiation (parents). The longer harvest led to higher plant height, length, production, and lignin content. There was an interaction (P<0.05) between varieties and harvest ages. Gamma irradiated Sorghum sudanense had a peak production at the age of 70 days, with a lignin content of 3.63%.

Abstract

  The objective of the study was to determine the effect of cassava pomace and protected soybean meal on dairy milk production and quality of mid lactating dairy cows. This research was conducted at Turen, Malang from January to April 2020. Twelve lactating Friesian Holstein dairy cows were divided into 2 groups so that each group consisted of 6, namely the control and treatment groups. The feed were a combination of forage and concentrate with a ratio of 35:65 in dry matter (DM). The control group received wet concentrate with DM content of 30.58%, 14.87% CP, and 75.06% TDN, while the treatment groups received concentrate with supplementation of cassava pomace 15% of DM ratio and protected soybean meal 45 g/l milk production. The variables observed were nutrient consumption, milk production and quality. Data between the two groups were analyzed using the Independent Sample T-test. The results showed that the addition of waste cassava and protected soybean meal increased (P<0.05) nutrient consumption (DM, OM, CP, CF, EE, and TDN). Milk production in the treatment group was higher (P<0.05) than control group (9.46 vs. 6.07 Ls/head/day). Milk protein production in the treatment group was higher (P<0.05) than control group (0.37 vs. 0.21 L/head/day). The content of milk protein and milk fat between the control and treatment groups was not significantly different (respectively 3.19 Vs 3.28; 4.46 vs 4.42 %). Milk protein and fat production in the treatment group was higher (P<0.05) than control group (0.21 vs 0.37; and 0.50 vs. 0.30 L/head/day respectively). The composition of glucose and blood urea in control and treatment dairy cows were not significantly different. In conclusion, giving cassava pomace and protected soybean meal to dairy cows during mid lactation increased nutrient consumption, milk production, milk protein production, and milk fat production but did not increase percentage of milk protein and fat. The treatment also did not affect blood glucose and nitrogen urea contents.

Abstract

The aim of this research was to identify the effect of feeding fermented Sargassum sp. as complete feed ingredient up to 20% of total feed on nutrient consumption and digestibility, and growth performance of thin-tailed sheep. Twelve female thin-tailed sheep aged 6 to 8 months with an average initial body weight of 14.13 ± 2.08 kg were divided into three groups. The treatments were control without fermented Sargassum sp. (S0), 10% fermented Sargassum sp. (S1), and 20% fermented Sargassum sp. (S2). Complete feed was formulated by isoprotein and isoenergy formulation, containing 16% of crude protein and 61% of total digestible nutrients. Complete feed was given at 3.5% of body weight (% dry matter) and drinking water was provided ad libitum. This research was done in 6 weeks with 14 days adaptation period and seven days of collection period. Growth performance was measured for 4 weeks after the adaptation period. The variables observed were dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), crude fiber (CF), nitrogen-free extract (NFE), and total digestible nutrients (TDN) consumption. The data obtained were subjected to one-way ANOVA (analysis of variance) and the difference existed (P value <0.05) between means were analyzed with Duncan’s multiple range test. The results showed that there was no significant effect of feeding fermented Sargassum sp. on nutrient intake, and digestibility of nutrients (P>0.05), however, S0 treatment appeared to have CP, CF, and EE intake, as well as digestibility of DM, CP, CF, and NFE higher than S1 and S2 treatment. The results showed that there was no significant effect of feeding fermented Sargassum sp. on nutrient intake, digested and digestibility of nutrient, absolute and relative weight gain as well as feed conversion.
