Abstract

The growth of several types of grass in the area of ​​mine re-vegetation is rapidly providing an opportunity to be used as forages despite the possibility of heavy metal contamination. The purpose of the study was to evaluate the effect of treatment of different levels of elephant grass (EG) (Pennisetum purpureum) planted at ex-coal mining reclamation on milk productivity and mineral contents of dairy cattle. This study used four lactating (second lactation) dairy cattle using Latin Square Design of 4 (treatments) x 4 (replications). Each period was 21 days consisted of 14 days of preliminary for feed adaptation and 7 days for observation. Treatments were P0 (0% ex-coal mining (EEG)+60% Farmer’s EG (FEG)+40% Concentrate), P1 (15% EEG+45% FEG+40% Concentrate), P2 (30% EEG+30% FEG+40% Concentrate), and P3 (60% EEG+0% FEG+40% Concentrate). The study observed variables of feed intake and efficiencies, milk production, milk quality, and mineral contents of milk. Results showed that EEG treatment at different levels did not affect fresh and dry matter intake. The highest fresh and dry matter intake was found in P0 treatment. There was no significant difference in giving EG planted at the ex-coal mining and the farmer’s land on the milk production and milk quality. The only significant differences (p<0.05) were found in mineral Fe and Mg contents of milk. The study concluded that giving EG planted at the ex-coal mining area until 60% of forage affected Fe and Mg contents of milk, but they are still in the safe limit.

Abstract

The most of protein requirement for cows is fulfilled by microbial protein. Increasing the protein from ration usually influences the milk production in dairy cows. However, the availability of dietary protein should support rumen ecosystem through microbial activity in the fermentation and digestion process. The aim of this study was to evaluate the protein levels of dairy cow ration on the rumen fermentability and digestibility using an in vitro method. Randomized block design with three levels of protein ration as a treatment and three times taken of rumen liquor as a block. The treatments were: R1= ration with low protein; R2= ration with moderate protein and R3= ration with high protein. The measured parameters were rumen fermentability (total VFA, N-NH3 and pH), in vitro dry matter digestibility (IVDMD) and in vitro organic matter digestibility (IVOMD). The results showed that there were significantly increase in dry and organic matter digestibility (p<0.05), due to increasing the level of dietary protein, but there was no effect in the fermentability, except a slight increase in N-NH3 concentration. The conclusion of this study was the highest level of protein ration enhances the digestibility, and showed a tendency for higher N-NH3.

Abstract

The aim of this research is to compare alternative inoculant source for in vitro rumen fermentation. In the first experiment, inoculant from fistulated cattle kept in LIPI and IPB (Fis1 and Fis2) and inoculant from Bogor municipality abattoir and IPB abattoir (Abo1 and Abo2) were tested for their pH, total bacterial count, and protozoal number using a complete block design with four replications. In the second experiment, the effect of the inoculant sources was tested on cornmeal (F1), soybean oil meal (F2), Napier grass (F3), and dairy cattle complete ration (F4) fermentability and digestibility including pH, VFA, NH3, IVDMD and IVOMD parameters. The results showed an unsignificant different protozoal number among inoculant sources. The pH of Fis2 rumen liquor was significantly lower (p<0.05) than others. The bacterial population was significantly higher (p<0.05) in Fis2 and Abo2 than Abo1, and Fis1. The inoculant pH after feed fermentability was not influenced by feed type but inoculant source with Fis1 was significantly higher (p<0.05) than Fis2, Abo2, and Abo1. The ammonia, VFA concentration, IVDMD, and IVOMD were influenced by interaction between inoculant sources and feed types. Although inoculant from cattle close to the laboratory (Fis2 and Abo2) were better in term of higher bacterial population, higher fermentability and digestibility for most type of feeds but other sources can be used in vitro study without differences in average fermentability and digestibility results. Key words: abattoir, fermentability, fistula, inoculant, in vitro

Abstract

The purpose of this study was to examine the influence of aflatoxins on rumen fermentation in vitro and obtained rumen bacterial isolates capable of binding aflatoxin. This trial consisted of three stages. The first trial was a reduction of aflatoxin in the rumen in vitro. The second experiment was the isolation and characterization of rumen bacteria that could bind aflatoxin. The third stage was to test the holding capacity of aflatoxin by rumen bacteria. This study used cow rumens. The Research design used a randomized complete block design (RCBD) factorial 2x3 and 2 replications. The first factor was the presence of aflatoxin (with and without the addition of aflatoxin), the second factor was the type of feed (diet and glucose), and the third factor was the time of incubation (0 and 4 hours). The results showed the presence of aflatoxin did not affect rumen conditions (pH, volatile fatty acid (VFA), and rumen lactic acid concentration), and the results obtained 6 isolates and isolation of rumen bacteria to bind aflatoxin up to 50%.

The experiment consist of two steps with the first step was microbiology measurement used a Randomized Block Design with 5 treatments level of Moringa leaf extract (P0= control; P1= 5%, P2 = 10%, P3 =15%, P4 =20%) and the second step was in vitro fermentability and digestibility measurement used Randomized Block Design with 7 treatments level of Moringa leaf in dairy cow ration (R0 = control, R1 = R0 + 2.5% Moringa leaf, R2= R0 +5% Moringa leaf, R3 = R0 + 7.5% Moringa leaf, R4= R0+10% Moringa leaf, R5=R0+12.5% Moringa leaf, R6=R0+15% Moringa leaf) which grouped by rumen fluids. Data analysis used analysis of variance and continued with Duncan’s Multiple Range Test. The measured variable were microbial rumen population (bacteria and protozoa), fermentability (N-NH3, VFA), microbial protein synthesis, dry matter digestibility (DMD), and organic matter digestibility (DMO). The results showed Moringa leaf extract significantly decreased bacterial population (p<0.05), but there was no effect on the protozoa population. Moringa leaf supplementation did not affect N-NH3, DMD, and DMO, but significantly influenced VFA concentration and microbial protein synthesis (p<0.01). The higher Moringa leaf supplementation showed decreasing total VFA concentration, but was still within the normal range for rumen fermentation (102.29-126.69 mM). Moringa leaf supplementation showed a quadratic effect on microbial protein synthesis with an optimal supplementation level of 5%, but decreasing at a level of 7.5% still within in normal range. It can be concluded Moringa leaf can be supplemented up to 7.5% in dairy cow ration. Key words: digestibility, fermentability, in vitro, moringa leaf, dairy cow

Abstract

The aim of this experiment was to study the effect of betel leaf meal (BLM) as feed additive on milk composition and somatic cell count of subclinical mastitis infected cow. The experiment design was a completely randomized design with five dietary treatments of BLM level and four replications in concentrate feed. The treatments were T0 (without betel leaf meal, as control), T1 (2% of betel leaf meal every day), T2 (4% of betel leaf meal every day), T3 (2% of betel leaf meal skip two days), and T4 (4% of betel leaf meal skip two days). Milk samples from the infected quarter would be analyzed every week of the experiment. Parameters measured were milk composition and somatic cell count. Data were analyzed by using analysis of variance (ANOVA) and the differences among treatments were examined by Duncan's multiple range test. Results showed that in T1 decreased somatic cell count by 83%, but the addition of BLM did not significantly affect milk composition. It could be concluded that the addition of 2% of BLM as a feed additive has the potency to prevent mastitis in lactating cows.

Abstract

This research investigated the potential of Javanese turmeric (Curcuma zanthorrhiza) and aromatic ginger (Kaempferia galanga) as natural feed additives in dairy cow diets, focusing on their effects on rumen fermentation characteristics and and protozoa population through an in vitro study. The study employed a randomized block design consisting of four treatments and three replicates, utilizing rumen fluid obtained from three fistulated Friesian Holstein bull dairy cows. The treatments were defined as follows: P0 = control diet; P1 = P0 + 10% Javanese turmeric; P2 = P0 + 10% aromatic ginger; P3 = P0 + 5% Javanese turmeric + 5% aromatic ginger. The parameters assessed included rumen pH, ammonia (NH3) concentration, total volatile fatty acids (VFA) concentration, and protozoa population. Data analysis was performed using analysis of variance (ANOVA), followed by Duncan’s multiple range test to identify significant differences (p<0.05). The results showed that none of the treatments significantly affected on the measured parameters (rumen pH, ammonia, VFA, and protozoa populations). The best results were observed in treatment P2 (10% aromatic ginger), which exhibited average values within the normal range across all parameters. The study concluded that dietary inclusion of Javanese turmeric and aromatic ginger, either alone or combined, did not disrupt rumen fermentation balance.
