In order to ascertain the effect of additional calcium carbonate into concentrate diet, on the performance of sheep fed ensiled king grass as a basal diet, a trial was conducted using 28 growing sheep ( average body weight 17 _+ 1 .4 kg). Based on body weight, the animals were grouped and randomized into four dietary treatments in block randomized design . Dietary treatments were (i) chopped king grass + 400 g of concentrate, (ii) ensiled king grass + 400 g concentrate + 0 % of calcium carbonate, (iii) ensiled king grass + 400 g concentrate + 5 % calcium carbonate and (iv) ensiled king grass + 400 g concentrate + 10 % calcium carbonate . Results showed that offering 5 % of calcium carbonate into concentrate diet increased (P < 0 .05) dry matter and nutrient intake of silage, but digestibility coefficients were similar (P > 0 .05) for all groups . No differences in the apparent digestibility of the nutrient components were observed, but crude protein decreased significantly (P < 0 .05) . A significant relationship ( P < 0 .01) was found between nitrogen intake (NI) and nitrogen retention (NR), and the equation was Â NR = - 0.1848 + 0.3788 NI ( r = 0.9 ) . Based on data found that feeding only ensiled king grass as a single diet could not meet the maintenance requirement of energy and protein, therefore, additional energy and crude protein sources is needed .

High producing ewes required high amounts of energy, which can not be met through feeding conventional ration. Therefore, supplementing energy should be done, especially protected-energy. The purpose of this study was to determine the effects of additional of protected fat/energy on the consumption of ration and the performance of ewes and lambs. Thirty-four local ewes were randomly allotted to four levels of by-pass energy groups, in which parts of energy content in the concentrate was replaced with rumen-protected fatty acids in the proportion of 0 (R1), 5 (R2), 10 (R3), and 20% (R4). Consumption, nutrient digestibility and animal performance (ewes and lambs) were determined by standard procedures. Results showed that the daily dry matter intake during pregnancy (g/kg BW0.75) did not differ among diet (72.1 + 2.56). The crude fibre intake varied slightly between treatment (P>0.05), those being slightly lower intake on the highest replacement of energy content in concentrate diet (R4). Dry matter digestibility were 52.4 + 0.24, 52.1 + 0.30; 51.8 +0.28; and 51.3 + 0.81 in groups R1, R2, R3, and R4, respectively, which were non-significantly different from each other. These results confirmed that the by-pass energy sources replacements did not affect rumen fermentation. The same tendency was also found for crude protein digestibility (P>0.05) i.e. 60.1; 61.8; 61.2; and 60.2 for R1, R2, R3, and R4 respectively. The average daily gain of ewes during gestation period was affected (P<0.05) by by-pass energy replacement and the effect was linear with increasing by-pass energy replacement. Significant difference was not found in the total birth weight of lambs and among dietary treatments. Lambs growth rate during the first 8 week of lactation was the highest on ewes fed diet containing the highest amount of by-pass energy sources (R4). It can be concluded that by-pass fatty acids can be used in ewesâ ration without affecting rumen fermentation and gave a positive respons to animal performance.

Ruminant production is limited by the quality, the sufficiency and the continuation of feed supply, especially during the dry season. The objective of the study was to find out the potency, type and quality of natural vegetation grown under cashewnut plantation. The study was carried out by exploration of existing natural vegetation resources in cashewnut plantation area. Results showed that native pasture growing under cashewnut plantation area comprised of dry-tolerant grasses and legumes, such as Setaria sp., Themeda sp., Calopogonium mucunoides, and Desmodium sp. The fresh yield and the dry matter production of natural vegetation grown under less than eight years old of cashewnut plantation was lower compared to those grown under cashewnut plantation of more than eight years old. This may be due to shading by the tree crop, which is known to reduce the photosynthetically active radiation reaching the ground of vegetation. It seems that, light is the critical factor affecting the growth of vegetation underneath tree canopies. Carrying capacity of native forages grown under cashewnut plantation was only 0.5 animal unit of ruminant/ha/year. Â Key words: Natural vegetation, cashewnut plantation, carrying capacity

This study was intended to determine the effects of increasing the ratio of banana trunk to soybean meal on intake, nitrogen excretion and lambs performance. Sixteen lambs (averaging 21.21 + 1.69 kg) were pen individually and fed a basal diet consisted of chopped fresh king grass and commercial concentrate and unlimited access of water. Lambs were randomly assigned to one out of four different ratio of banana trunk to soybean meal as feed supplements, i.e. (R0) 0:1; (R1) 1:1; (R2) 2:1 and (R3) 4:1. Results showed that the inclusion of banana trunk had no adverse effect on lambs performance. As it is expected, altering the ratio of banana trunk to soybean meal increased (P < 0.05) dry matter intake of forage as well as total dry matter intake. The digestion coefficient of dietary ration was not affected (P >0.05) by feed supplement. Despite of no difference was observed in the coefficient of nitrogen digestibility, apparent fecal and urine N-output were significantly (P < 0.05) affected. The highest ratio of fed supplement (R3) tended to decrease nitrogen retention. Overall data indicated that lambs offered basal diet supplemented with R2 treatment accumulated more N per-day, than those fed other treatments, and consequently lambs performance was the best on those fed R2 treatment.

Production respons was related to rumen undegradable protein feeding. Twenty-six local late pregnant ewes are penned individually and allocated to four dietary treatment groups of feed supplement, containing different amount of protected soybean meal and provided 0% (R1), 10% (R2) 20% (R3) and 40% (R4) crude protein of feed supplement respectively. Diets were fed until the first 8-week of lactation phase. Results showed that the mean of total dry matter intake (DMI) during late pregnancy was 3,42% of body weight (BW). Dietary treatments of protected-protein tended to increase daily mean intake of dry matter (P>0.05), ie. 76.9; 77.25; 77.49 and 78.81 g/kg BW 0.75 for R0, R1, R2 and R3 respectively. A similar trend was noted in daily intake of crude protein with the mean of 9.75; 10.31; 10,75 and 12.1 g/kg BW0.75 (for R0, R1, R2 and R3 respectively) and were not different significantly (P>0.05) among dietary treatments. Increasing the amount of protected-protein in the ration influenced (P<0.05) the daily live weight gain (ADG) of ewes during the late phase of gestation which was 104.4, 99.4, 120.8 and 148.14 for R0, R1, R2 and R3 respectively. Feed efficiency (DMI/ADG) improved as substitution of protected-protein increased. The total birth weight of lambs (g/ewe) was not significantly different (P>0.05), by increasing level of protected-protein in the ration, averaging 3.2 kg/ewe. Increasing protected-protein, increased (P<0.05) the daily gain (g/ewe) of lambs during the first 8-week of lactation, and it was 127, 131, 165 and 211 g/ewe/d for R0, R1, R2 and R3 respectively. Consequently, the weaned weight at 8- week of ages increased significantly different (P<0.05) as the amount of protected-protein in the diet increased.

An experiment was designed in order to study the crude protein and energy requirement of Ettawah Cross growing goats. Twenty seven kids (average body weight of 11.80 + 1.4 kg) were used and randomly allotted to a 3 x 3 factorial arrangement of treatments, consisting of three different levels of crude protein and three levels of energy. Results from this experiment showed that animal performance was effected by dietary treatments. Increasing levels of energy ration significantly (P<0.05) decreased the dry matter intake, with overall mean values were 3.0; 2.8 and 2.5% of body weight for low, medium and high levels of energy respectively. Dietary treatments increased energy (EM) and crude protein intake, and overall values were 0.2046 + 0.016 Mkal/kg BW0.75 and 8.20 + 2.473 g/kg BW0.75 repectively. Positive response on animal performance was also effected by dietary treatment, with overall mean value of 86.40 + 29.59 g head-1day-1. The highest response on animal performance (ADG 123.3 g) was found on kids fed diet containing combination of low level of energy and high level of crude protein. Meanwhile, the lowest average daily gain (45 g) was resulted by kids fed ration containing combination of high level of energy and low level of crude protein.

Thirty-six Javanese thin-tail ewes were set out to study the energy and crude protein requirements for the last eight-week of pregnancy. The ewes were randomlly assigned to a 3 x 3 factorial arrangement and offered nine diets comprising three levels of energy (low, medium and high) and three levels of crude protein (low, medium and high) with four ewes per treatment. The diets were pelleted and offered four times daily at approximately in the same amount. Results showed that, despite a difference of energy concentration in the diets, dry matter intake was not significantly (P>0.05) affected, but crude protein concentration was (P<0.05). Energy concentration in the diet also had no effect (P>0.05) on protein intake. However, protein concentration in the diets significantly affected on protein intake and protein excreted in the feces. Moreover, an interaction between energy and protein levels was not detected on energy and nitrogen availability utilization. This study demonstrated that a high efficiency on nitrogen utilization could be achieved on low crude protein diets. It was also found that crude protein and energy requirements for maintanance during pregnancy phase were 0.67 g/kg BW0.75 and 0.425 MJ EM/kg BW0.75 respectively.

Thirty-six Javanese thin-tail ewes in the end of late pregnancy phase were set out to study the energy and crude protein requirements during the first eight-week of lactation phase. The ewes were penned individually in doors and randomly assigned to a 3 x 3 factorial arrangement, consisting of three levels of energy (low, medium and high) and three levels of crude protein (low, medium and high) diets with four ewes per treatment. The diets were pelleted and offered four times daily in approximately equal amount. Feed intake, nutrient digestibility, body weight and milk production were recorded. Results showed that, total lamb birth weights was not affected, but protein content on the ration treatments significantly altered (P<0.05) milk yield and composition. Dry matter intake due to feeding treatments was not significantly affected (P>0.05), while crude protein content on the ration highly significantly affected (P<0.01). Based on data recorded, the energy and protein requirements for ewes during lactation phase are highly significantly depended on ewesâ live weight, milk production and the ratio of energy metabolism and crude protein of the ration. It was concluded that in order to fulfil the crude protein and energy needs of the ewes during lactation phase, the ration given should contain crude protein and energy as much as 16% (based on dry matter) and 13.4 MJ/kg dry matter respectively.

A series of experiments has been conducted to study chemical processing method of feather meal using hydrocloric acid (HCl) and to evaluate the biological values by in vitro and is sacco methods of the hydrolitic feather meal (HBA). Feather meal was hydrolyzed using four levels of HCl concentration (i.e.0, 6, 12 and 24%) in three incubation times (i.e. 2, 4, and 6 days). The hydrolysis reaction was carried out in closed container in the ratio of feather meal and HCl of 2:1 (w/v). In vitro evaluation was conducted to measure dry matter (DM) and organic matter (OM) digestibility, DM solubility, ammonia (NH3) and volatile fatty acid (VFA) content. In sacco to observe the degradation of HBA crude protein. Results of in sacco evaluation in rumen showed that soluble and degraded crude proteins (CP) were significantly only affected by HCl concentration (P<0.01). The rate and the amount of degraded protein in 24 hours inclution in the rumen were affected by the HCl concentration and incubation time of hydrolysis. More amino acid degradation occurred on longer time showed that HCl had quadratic effect (P<0,01) on pH of HBA. However durations of hydrolysis did not significantly affect acidity (P>0.05). In vitro DM and OM digestibilities of HBA increased as the concentration of HCl was increased. The increase of DM digestibility followed the equation Y = -0.0231x3 + 0.7323x2 â 1.5716x + 12.383 (r = 0.994); and the OM digestibility followed the equation Y = -0.0229x3 + 0.7194x2 â 1.0606x + 15.951 (r = 0.993). Time of incubation, on the other hand, did not affect OM and DM digestibilities (P>0.05). DM solubility of HBA was significantly affected by HCl concentration and the length of incubation time (P<0.01). The increase of DM solubility was followed by the increase of NH3 content (P<0.01). The relation between DM solubility and NH3 content followed the equation Y = 0.4365x + 5.4047 (r = 0.966). The increase of DM solubility followed the equation Y = -0.027x3 + 0.9596x2 â 4.8142x + 5.3878 (r = 0.973) and the increase of NH3 content followed the equation Y = -0.0085x3 + 0.3175x2 â 1.4139x + 7.0889 (r = 0.992). Result of in sacco evaluation showed that fraction of crude protein (CP) disolved and fraction of CP degraded in rumen was significantly affected by HCl concentration (P<0.01), while the rate of CP degradation and the amount of fraction degraded during 24 hours in the rumen were affected by the HCl concentration and the durations of hydrolysis (P<0.01)Â indicating that more feather meal protein was hydrolized by HCl, therefore weakened or cut the chain of amino acid in the feather protein. Treatment with 12% HCl for 4 days hydrolysis of feather meal resulted in CP fraction degradation during 24 hours incubation in the rumen of 53%, indicating that the potency of CP of HBA as rumen by pass protein was 47%.

Protein with low resistant of rumen degradability must be protected, which part of its protein could reach post ruminal and able to supply amino acids for ruminant. The experiment was conducted to obtain the best ratio of soy bean meal with banana stem juice as feed supplement protecting protein. Rumen degradability using rumen fistulated sheep were evaluated in saccous at incubation times of 0, 2, 4, 6, 12, and 24 hours.Â The best ratio in the in sacco experiment was used for further in vivo experiment. Fifteen growing lambs with average live weight of 18.6 Â± 2.2 kg were grouped according to body weight in trial with a simple randomized design. Three treated rations were R0 = control diet with 0% protected soy bean meal, R50 = diet with 50% protected soy bean meal, and R100 = diet with 100% protected soy bean meal. All diets were iso nitrogen and iso energy (CP 18% and TDN 75%). Diet consisted approximately 30% king grass and 70% concentrate. The experimental diets were offered for 12 weeks. The result from in sacco experiment showed that the best ratio between soybean meal and banana stem juice was 2:1 w/v (R2). This mixture had the highest rumen undegradable dry matter and protein. Result from in vivo experiment showed that the intake and digestibility of dry matters, the intake and digestibility of crude protein. The intake and digestibilities of dry matter intakes and digestibilitie of crude protein, pH value, NH3-N, total bacteria, purin and total VFA in rumen fluid were not affected by feed supplement. The same average body weight at the beginning of study resulted same body weight at the end of study. The ADG of R50 and R100 (138.1 and 122.2 g) were respectively not different with the control, RO (120.9g). It was concluded that soy bean meal and banana stem juice 2:1 w/v was the best ratio, but as feed supplement with high resistant rumen degradable protein can not produce higher growth rate than the control group.
