Abstract

The study aimed to investigate the effects of offering different levels of ensiled  or fresh Indigofera arrecta in completete diets on the feed consumption, ADG, ruminal fermentation characteristics and blood metabolites concentrations in growing goats. The I. arrecta/concentrate ratios of the complete diets were set at 85/100,75/100 and 65/100. Thirty weaned-male goats were used in the study, and were randomly allocated to one of the six treatments (5 heads per treatment). The diets were offered at 4% BW and the animals were weighed weekly. The study was arranged  as a completed randomized design. Feed intake, average daily gain, feed efficiecy ratio, ruminal fermentation (pH, NH3 and VFA characteristics and blod metabolites (glucose and urea) were analysed. Feed intake of goats receiving ensiled Indigofera arrecta were lower (P < 0.01) compared to those receiving fresh I. arrecta. ADG were higher (P > 0.01) when goats were fed diets with lower level inclusion of Indigofera arrecta. Efficiency of feed utilization decreased (P < 0.01) when ensiled Indigofera arrecta was used in the diets, but it was not affected (P > 0.01) by the inclusion level of I. arrecta in the diets. Ruminal pH was not affected by ensiling process, but ruminal NH3 concentrations were greater (P < 0.01) in goats receiving fresh Indigofera arrecta. Ruminal VFA levels were also greater (P < 0.05) in the group offered fresh Indigofera arrecta, but the differences were not significant (P > 0.05) when diets consisted of 65% Indigofera arrecta in the complete diets. Increased  rate of Indigofera arrecta inclusion in the diets resulted in lower (P < 0.01) counts of ruminal microbial population. The concentration of plasma urea nitrogen were neither affected by the ensiling process nor by the levels of I. arrecta inclusion in the diet (P > 0.05), however, the plasma glucose level decreased (P < 0.05) as the level of I. arrecta inclusion in diets increased. It is concluded that I. arrecta could be used as the sole fresh or ensiled foliage in complete diets, although the performances of goats were better when  fresh I. arrecta was offered. The level of I. arrecta inclusion in complete diets was recommended at not greater than 65%. Key Words: I. arrecta, Silage, Complete Feed, Goat

Abstract

A study was conducted to evaluate the responses of lambs on the infection of Haemonchus contortus and the level of energy supplements. Forty eight male lambs, 3-4 months old were used in a factorial experimental design (2x2x2) which lasted for 9 weeks. The factors were breed (Local Sumatra and Sungai Putih: 50% Local Sumatra, 25% St. Croix; 25% Barbados Blackbelly), level of Haemonchus infection (3,000 L3 and 1,500 L3 per week) and level of energy supplement (2,900 kcal/kg DM and 2,300 kcal/kg DM). Infection at 3,000 L3 decreased (P<0.05) ADG of lambs of both energy levels. An extremely low ADG (10-16 g) was observed in 3000 L3 group given low energy level. Body condition of lambs fed high energy level was constant over the experiment, but it decreased at the rate of 0.9 to 1.1 unit at the low energy supplement. EPG was higher (P>0.001) in the 3000 L3 group, was lower (P<0.05) in the Local Sumatra, but not affected (P>0.10) by energy level. PCV was not affected (P>0.10) by infection levels, but lower (P<0.01) in the low energy group or in the St Croix crosses. Eosinophil and serum protein concentration were not affected by energy and infection level, but they were higher (P<0.01) in the local Sumatra. It was concluded that strong effects of level of infection and genotype was detected to influence the impact of Haemonchus infection in lambs. However, the effect of energy levels was less consistent as judged from the EPG, PCV, eosinophil and serum protein data.   Key words : Energy level, genotype, infection level, Haemonchus contortus, lambs

Abstract

The availability of forages is a critical factor that determine the sustainability of the animal-plantation production system. In this typical production system, cover crops could be an important sources of forages to support the animal production. The study is aimed to evaluate the nutritional quality (chemical compositions, intake, digestibility and N balances) of herbaceous legumes namely Arachis pintoi and Arachis glabrata having potential for used as alternative cover crops in plantation. Centerocema pubescens, a conventional cover crops used in plantation, was used as control. Twenty-one mature male goats (16-18 kg) were used in this experiment. The animals were put in individual metabolism cages, divided into three groups (7 animal per group) based on the body weight, and were randomly allocated into one of the three forages. The experiment was run in a Completely Randomized Design. The animals were allocated to an adaptation period for 14 days, followed by intake measurement for 5 days and fecal and urine collection for the next 7 days. During the fecal and urine collection forages were offered at 90% of the maximum intake. Chemical analyses showed that the DM and OM contents were relatively equal among the forages, but the crude protein content of C. pubescens (23.56%) are relatively higher than those of A. pintoi (16.94%) or of A. glabrata (15.19%) The fiber (NDF) content was also relatively higher in C. pubescens (59.37%) than in A. pintoi (16.94%) or A. glabrata (41.50%). The forage intake was highest (P<0.05) in goats fed C. pubescens (493 g/d), and were not different (P>0.05) between goats fed A. pintoi (466 g/d) or A. glabrata (453 g/d). A similar trend was seen when intake was expressed as % BW (3.80, 3.50 and 3.40, respectively) or as g/kg BW0.75 (42.4, 39.5 and 38.4, respectively). The digestion coeficient of DM (81.3%) or OM (83.5%) were highest (P<0.05) in A. pintoi and were not different (P>0.05) between A. glabrata (71.9 and 73.2%, respectively) and C. pubescens (73.7 and 74.2%, respectively). The trends were the same with the digestion coeficient of ADF and the energy. The ADF digestibility were 67.8, 55.9 and 54.5% in A. pintoi, A. glabrata and C. pubescens, respectively). The energy digestibility were 81.8, 67.5 and 69.4% in A. pintoi, A. glabrata and C. pubescens, respectively. The N balances were positive in goats fed these three forages, but the highest (P<0.05) N retention was observed in goats offered C. pubescens (17.7 g/d) as compared to those fed A. pintoi (9.4 g/d) or A. glabrata (7.7 g/d). The higher intake level in goats fed C. pubescens and its higher N content seemed to be the main reason for the highest N retention. It is concluded that based on these nutritive parameters, C. Pubescens has superior nutritive quality compared to A. pintoi and A. glabrata, while the A. pintoi seemed to be better than the A. glabrata.     Key Words: Legumes, Cover Crops, Nutritive Quality, Goats

Abstract

Grazing cycle beyond parasite survival time can reduce the level of parasite contamination, but at the same time it may depress the quality of available forage for animal production . A study was conducted to evaluate the effects of grazing management systems on the production and quality of Brachiaria brizantha and the performance of lamb grazing this pasture . A total of 72 male lambs aged from 3 to 4 months were used . The lambs were divided into 3 groups and randomly allocated to receive one of the following grazing treatments : GMl-pastures were grazed for 6 weeks and then rested for 6 weeks, GM2-pastures were grazed for 1 week and then rested for 6 weeks, and GM3-pastures were grazed for 12 weeks and then rested for 12 weeks . The herbage mass measured before and after grazing was greatest (P<0.01) forGM3. Canopy compositions before grazing   as not different (P>0 .10) among the three grazing methods, while after grazing, the proportion of stem fraction was highest and leaf fraction was lowest for GM3 (P<0 .01) . The in vitro dry matter digestibility (IVDMD) of plucked samples were not different (P>0 .10) among the grazing methods. The crude protein (CP) concentration was lower (P<0 .05) for GM3 as compared for GM 1 and GM2, and a difference of two percentage unitmay be of biological important. The changes in IVDMD and CP concentration of the plucked samples collected throughout grazing cycle remained reasonably steadily . Average daily gains (ADG) were low and not different (P>0 .10) across grazing treatment and ranged from 29 to 35 g. It was concluded that a 12-week grazing cycle while could increase the herbage mass of Brachiaria brizantha did not decrease feed intake, the digestibility and the crude protein concentration of the consumed forage . Therefore, this gazing system could be considered as a means to control parasite establishment on pastures.   Key words : Grazing systems, herbage mass, forage quality, sheep

Abstract

The effects of grazing systems, levels of feed supplementation and genotypes of sheep on the establishment ofHaemonchus contortus were studied in 36 St . Croix x Sumatra crosses (HC) and 36 Sumatra (S) male lambs . The lambs were artificially infected with Haemonchus larvae (L3) at a rate of 3,000 L3 per animal and fed concentrate supplement at 0 .5% body weight (BW) or at 1 .6% BW. The animals grazed clean Brachiaria brizantha pastures . Lambs grazing GM1 (grazing system with a 6-week rotational cycle) had egg counts of 3,936 t 1 .525 at week 18, and 29% of the lambs had PCV ranging from 7 .8 to 14 .6% . Lambs in GM3 (grazing system with a 12-week grazing cycle) had egg counts of 6,714 t 2,075 at week 28, and 24%ofthe lambs had PCV ranging from 7 .9 to 13.3% At these periods, all lambs in both GMI and GM3 were dosed with anthelmintics to prevent the death of the animals . Although the overall mean egg counts (4,543 t 318) of lambs on GM2 (grazing system with a  1-week grazing and 6-week resting periods) were higher (P<0 .001) than on GMI (2,944 t 325) or on GM3 (2,159 t 418), it was achieved without dosing with anthelmintics, since only I 1%ofthe Iambs in GM2ever reached PCV values less than 15%. Lambs fed supplements at 1.6%BW had lower (P<0.001) egg counts and higher (P<0 .001) PCV and serum protein than lambson 0.5 %BW supplement group . Egg counts and PCV values were not different (P>0 .10) between HC and the S lambs when fed supplement at 0.5% BW, but on 1 .6% supplement BW group, the egg counts were lower (P<0.001) in HC. It is concluded that a one-week grazing and a six- week resting system was superior than grazing systems with a 6- or 12-week rotational cycle . Improving the nutritional status of lambs by increasing the level of supplement offered could depress the establishment of Haemonchus in the Iambs . The HC and S lambs showed similar response to supplements at 0 .5% BW, but at 1 .6% BW the HC responded better than the S.   Key words: Grazing management, Haemonchus contortus, feed supplement, sheep

Abstract

The study was aimed: 1) to evaluate the effects of using different additives on the quality of pineapple waste-silage (SLN), and 2) to investigate the responses of goats fed with PAS as a basal feed. Pineapple processing wastes include skins and the pulp left after cannery wastes are pressed to extract the juice. Six additive treatments were used in the processing of pressed pineapple wastes, namely 1) urea (5% DM), 2) Urea (2% DM) and cassava meal (3% DM), 3) molasses (5% DM), 4) urea (2.5% DM) and molasses (2.5% DM), 5) fermented-juice lactic acid bacteria (5% DM), and 6) without additives. Fermentation periode were set at 9, 12, 15, 18 and 21 days. The best SLN obtained from those treatments was then used in feeding trials. Twenty male Boer x Kacang crosses with an initial body weight averaging 13.2 ± 1.9 kg were used in this experiment. The animals were allocated to one of the following feed treatments, in DM: A) Grasses (75%) + SLN (25%), B) SLN (75%) + Concentrates (25%), C) SLN (50%) +Concentrate (50%), and D) SLN (25%) + Concentrates (75%). Using molasses as additive material at 5% and 15 days of fermentation period gave the best chemical and physical characteristics of the SLN. Its crude fiber content decreased and it showed the lowest pH (4.7) The silage showed temperature at 280C, and its taste was sour, and no fungi contamination. The DM and OM intakes and DM, OM and N digestibility were not different (P>0.05) between the animals fed 75% Grass/25% CON and 75% SLN/25% CON. When the proportion of concentrates in the rations was increased, the feed intake and digestibility were increase significantly (P<0.05). ADG (71.3 vs 68.8 g) and feed efficiency (11.2 vs 13.4) was similar between the 75% Grass/25% CON and 75% SLN 25% CON groups. ADG increased significantly (P<0.05) when the proportion of concentrates in ration was increased to 50% (82.6 g) or to 75% (89.1 g). N retention was positive in all treatments, and it was increased significantly (P<0.05) as the proportion of concentrates in ration increased. It is concluded that pineapple wastes could be preserved to silages using molasses as additive material. Pineapple waste silage could be used as roughage to substitute grass in ration. When fed with the pineapple waste silage the responses of goats will increase as the proportion of concentrates in the ration increased. Key Words: Pineapple Wastes, Silages, Goats

Abstract

To study the effect of utilization of passion fruit hulls (Passiflora edulis Sims f. edulis Deg) as feed component on consumption, digestion and nitrogen retention in kacang goats, a trial was conducted using 20 young kacang goats (average initial body weight 23.73±2.16 kg). The experiment was arranged in completely randomized design consisting of 4 diets and 5 replications. Animal were randomly allocated into 4 diets (0, 15, 30, 45% of passion fruit hulls). Each diet contains 2550 Kcal/kg metabolism energy and 14% crude protein. The feeding level was set at 3.8% of body weight based on dry matter. The results of the experiment showed that average dry matter intake, nutrient digestibility, and nitrogen retention were not affected by level of passion fruit hulls (P>0.05), although nutrient digestibility and nitrogen retention tended to decrease with the increasing level of passion fruit hulls. It was concluded that passion fruit hulls can be used till 45% level in the diet. Key Words: Passion Fruit, Consumption, Digestibility, Nitrogen Retention, Kacang Goat

Abstract

The reproductive responses of local Sumatra ewes on the continuous urea-molasses supplementation was studied in 116 ewes for 21 months. The animals were divided into two groups and randomly allocated to urea-molasses supplement and grazing in rubber plantation or grazing in rubber plantation only (control). Both groups were allowed to graze for 8 hours a day. The urea-molasses mixture contained 3% urea (kg/kg) and were fed to the supplemented ewes ad libitum. The number of lambs born from supplemented ewes were greater than control (166 vs 114 heads). This was associated with the higher (P<0.05) litter size and the shorter lambing interval of supplemented ewes compared to those of unsupplemented ewes (1.34 vs 1.24, and 216 vs 232 d, respectively). Birth weight were not different (P>0.10) between the treatments (1.79 vs 1.61 kg), but weaning weight of lambs born to the supplemented ewes were greater (P<0.05) than the unsupplemented ewes (8.90 vs 7.55 kg). The ewe’s weight after parturition and the weight of lambs weaned per year were also greater (P<0.05) in the supplemented group compared to the control (22.7 vs 20.6 kg and 20.2 vs 15.1 kg, respectively). It was concluded that urea-molasses mixture was a good feed supplement for ewes grazing in rubber plantation. The urea-molasses supplementation clearly had positive effects on ewe and lamb productivity.   Key words : Urea, molasses, ewes, reproductive performances

Abstract

The availability of feed and their efficiency of use throughout the year represent the most important constraint affecting the productivity of animals in any agro-ecosystems. Beside being the largest contributor to the total production cost, logistically feeds need to be available on a daily basis across the animal’s life time. In order to be competitive, goat production system must be directed toward the optimum utilization of inconventional feedstuffs such as crop residues and agro-industrial by-products. The horticulture crops provide various crop-residues and by products from the processing of its main products. These biomass are potential feedstuffs that could be used to support the production of goats. The processing of passion fruits (Passiflora edulis) yield by products such as fruit shells and seeds. These products are good energy and protein sources for growing goats. Oriental radish (Raphanus sativus) by-products composed by damaged root parts and culls have high digestible energy and low ether extract content, but have very high moisture content. The pineapple by-products composed by the peel and bagasse of the fruit could be used as energy source for goats. Other horticulture by-products or residues such as citrus pulp, abandoned citrus fruit, forages from Ipomea batatas are of great potential as feeds for goat production. Preserving technology like ensiling could be implemented in utilising those biomass categorized as wet by-products such as pineapple and oriental radish by-products. The technology of complete feed is an effective means in utilizing some of those products with relatively low palatability or to increase its inclusion level in diets. Introducing shade-tolerant forage species as intercrops such as Stenotaphrum secundatum,  Brachiaria humidicola and Arachis pintoi in the citrus plantation should increase feed capacity of the area. The multi-purpose trees such as Indigofera sp. and Calliandra calothyrsus both are adaptable to the high altitude area are valuable feeds due to their high nutritional quality. Generation of technology that could maximize the utilization of those biomass as feeds for goat production is necessary. Some technologies that are relevant to that purposes including: 1) ensiling with appropriate inoculants that create optimal fermentation to preserve the product and to prolong the aerobic stability of the silages; 2) ensiling with appropiate absorbants for maximum effluent retention, intake and preference of the silage; 3) the utilization of fibrolytic bacteria; 4) utilization of fibrolytic enzymes in complete feed; and 5) supplementation strategy to optimize the rumen function for maximum utilization of basal diets. Because most of the feedstuffs mentioned above relatively vary in their nutritional quality and quantity, it is suggested that feed budget system, which is based on the availability of feed rather than the feeding standard system which is based on the animal’s nutrient requirement is a more relevant feeding system for goat production.

Abstract

The integration of goats and palm oil plantation is prospective agricultural production systems that exploit the complement relationship among various components in the system . The main components are the oil palm trees, vegetation underneath the trees, processing plant of palm oil bunch, and the goat . The estimation of carrying capacity of the plantation system is based on the quantitative analysis on nutrient supply from various feed resources in the plantation system and nutrient requirements for goat production . The goat demographic parameters, such as, prolificacy, fertility and fecundity are used to estimate the goat population size, dynamics and structures . The development of production model could be based on a certain production target, such as the number of animals sold or the amount of income (demand driven approach), or based on the availability of certain resources such as feed supply (supply driven approach) . Using the demand driven approach, and considering 6000 heads of oneyear old goats to fill the Malaysian market as the production target, it is calculated that a population size of 3,636 does and 810 ha of palm oil plantation are required to meet this production target . In a typically medium-size oil palm plantation system (500 ha of oil palm plantation) with one unit of small-scale palm oil bunch processing plant ( l ton/hour), the potency to supply metabolisable energy from various feed resources in the system is 2,778,800 Mcal/year, equivalent to a carrying capacity of 5,155 Goat Units/year . This system could carry 2,951 does and 295 bucks to produce 1,116 heads of one-year old goats annually . A medium-size oil palm plantation without processing plant unit, is potential in supplying metabolisable energy of 1,983,300 Mcal/year, equivalent to a carrying capacity of 3,680 Goat Units/year . In order to fill the export market to Malaysia, a number of 10 units of medium sized plantation with small scale plant processing or a number of 17 units medium scale plantation without processing unit are required . Using similar approach, the potential of either large-scale or small-scale plantation system to produce goat in an integrated-production system could be estimated . Key words : Integration, palm oil plantation, carrying capacity, goat
