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

This study was aimed to investigate the preferences and nutritional qualities of four mulberry species (Morus cathyana, Morus nigra, Morus indica and Morus multicaulis) in goat diet. Foliages were fed to six adult Boer x Kacang goats in a cafetaria style for preference analyses. Nutritional qualities (feed intake, apparent digestibility, N balances, rumen fermentation characteristics) and blood metabolites were measured in a digestion trial. Twenty male goats were used in a completely randomised arrangement of four treatments (mulberry species) and five replications. The selectivity indices were +0,389, -0,156, -0,154 and -0,234 for M. multicaulis, M. nigra, M. cathyana and M. indica, respectively, indicating that M. multicaulis was the most  and M. indica was the least preferred species. When fed as the sole foliage  the DM intake was higher (P<0.05) in  goats offered M. multicaulis (780 g/d) and M. nigra (718 g/d) compared to those fed M. cathyana (637 g/d) and M. indica  (598 g/d). The DM intake were equal to 38.6; 35.5; 31.5 dan 29.6 g/kg BW, respectively. The DM apparent digestibility were not different (P>0.05) among the species ranging from 60-65%. The N balances (N retained) was highest (P<0.05) in the M. multicaulis group (16,7 g/d) and was lowest in the M. indica (12,3 g/d) and M. cathyana groups (11,7 g/d). The rumen pH and  total VFA concentration was not diferent (P>0,05) among treatments. The ammonia concentration was higest (P>0,05) in the M. multicaulis and was lowest in the M. indica and M. cathyana groups. The bacteria and protozoa population was not different (P>0,05) among the treatments. It is concluded that M. multicaulis was more preferred by goats compared to  M. nigra, M. indica and M. cathyana, but all species have potential as foliages for goats as shown by its high intake, digestibility and rumen fermentation rates.

Abstract

The study was aimed to evaluate several nutritional quality parameters (chemical composition, intake and digestibility) in goats of S. secundatum and B. humidicola known to be highly and moderately shade tolerant species. The species of Pennisetum purpureuphoides was used as a control diet. These forages were offered to 21 male Kacang goats with an average body weight of 15.2 kg. The animals were divided into three groups based on the body weight, and were randomly allocated to one of the three forages species in a Completely Randomized Design. During the adaptation period (14 days) and the intake monitoring period (5 days) after the adaptation period the forages were offered ad lib. During the feces and urine collection period (7 days) feed was offered at 90% of the maximum  intake to minimize the intake fluctuation. The dry matter content of S. secundatum (332 g kg-1DM) and B. humidicola (321 g kg-1DM) were relatively higher than P. purpureuphoides (211 g kg-1DM), while the organic matter content were relatively equal among the three forages species. The crude protein content of S. secundatum (83 g kg-1DM) and B. humidicola (85 g kg-1DM) was almost identical, but were lower than that of P. purpureuphoides (111 83 g kg-1 DM) The NDF and ADF contents were relatively similar among the forage species. The dry matter (DM) intake of goats fed S. secundatum (588 g d-1) or fed B. humidicola (577 g d-1) did not differ (P>0.05), but it was higher (P>0.05) than dry matter  intake of goats fed P. purpreuuphoides. The similar trend was shown when DM intake was expressed in the percentage of body weight (3.60%, 3.55% and 2.77% BW, respectively) or when expressed as gram per kg BW0.75 which were 35.5, 35.6 and 27.7 g/kg BW0.75 respectively. The digestion coefficient of DM and OM were not different (P>0.05) between S.secundatum and B. humidicola, but it was higher than that in P. purpureuphoides. The digestion coefficient of energy were not different among these forages. The N balances were positive (3,0–3,6 g d-1) in goats offered these forages. It is concluded that the nutritional qualities of S. secundatum and B. humidicola were comparable, and it is relatively higher that the P. purpureuphoides when offered to goats as the sole feed.

Abstract

Twenty weaned male goats (F1 of Boer x Kacang) with initial weight of 9 to 12 kg and ages ranging between 3.0 and 4.0 months were used in a study to evaluate the increasing inclusion of Indigofera sp foliage as a source of protein in diets based on chopped Brachiaria ruziziensis for growing goats. Five goats were allocated to one of four treatments in a randomised block design. The diet treatments were: T0 (control diets): B. ruziziensis (100%), T1 (85% B. ruziziensis + 15% Indigofera sp.), T2 (70% B. ruziziensis + 30% Indigofera sp.) T3 (55% B. ruziziensis + 45% Indigofera sp.) all on DM basis. Feed (DM) was offered  daily at 3.5% BW. The content of CP in Indigofera sp is relatively high (258 g/kg DM), while the NDF (350.7 g/kg DM) and ADF (232.2 g/ kg DM) concentrations were low. The content of secondary compounds such as total phenol (8.9 g/kg DM), total tannin (0.8 g/kg DM) and condensed tannin (0,5 g/kg DM) were considerably low. The inclusion of Indigofera sp foliage in diets increased (P < 0.05) the DM, OM, CP, NDF and ADF digestibilities. The digestibility of DM (601,0 g/kg DM), OM (625 g/kg DM) and CP (699.0 g/kg DM) were highest in the T3 diets. DM intakes were greatest in the T2 and T3 diets (P < 0.05). Total gain increased 39, 78 and 85% in T1, T2 and T3 respectively, compared to that in the control diet. Daily gains were highest in the T3 (52.4 g) and T2 (50.5 g) diets, but feed efficiency was highest (P < 0.05) in the T3 diets (0,12). Feed efficiency were not different (P > 0.05) among the T0,T1 and T2 diets and ranged from 0.08 to 0.09. It is concluded that the foliage of Indigofera sp could be used as feed supplement to supply proteins with low tannin contents. In a grass-based diets Indigofera sp colud be used at the level of 30 to 45% (DM) for growing kids. Key Words: Indigofera, Inclusion Level, Feed Intake, Digestibility, ADG, Goats

Abstract

One of the main constraints in increasing livestock productivity in the tropical region is the scarcity of good quality feed throught the year, particularly during the long-dry season. Being a leguminous tree, Indigofera sp known to be tolerant to dry climate and salinity, should be considered as alternative fodder for ruminant animals. This study is aimed to investigate the productivity and some nutritional quality of Indigofera sp under different interval and hight of defoliation. The experiment was designed in a randomized block of factorial treatments. The factors were interval of defoliation (30, 60 and 90 days) and hight of defoliation (0.5, 1.0 and 1.5 m above ground level). Indigofera sp was planted in 4 x 3 m plots of 36 plots (4 replications) and were harvested at 8 months old. The DM production, chemical composition and in vitro digestibility were measured according to the treatments. The highest DM productivity was (33.25 t ha-1 y-1) at defoliation interval of 90 days and defoliation hight of 1.5 m, and was not different (P > 0.05) from the treatment combination of 60 days defoliation interval and 1,5 m defoliation hight (31.23 t ha-1 y-1). The highest leaf/stem ratio was 2.6 (P < 0.05) in the 30 day defoliation interval across the defoliation hight. The OM content of Indigofera sp was not affected by defoliation treatments and ranging from 884.6 to 906.8 g/kg. The highest NDF and ADF contents were (P < 0.05) in the 90-d defoliation interval and 1.0 m (387.9 and 272.6 g/kg, respectively) and were not different (P > 0.05) for the 90-d defoliation interval and 1.5 m defoliation hight (385.6 and 267.0 g/kg, respectively). The crude protein content was lowest (P < 0.05) in the 30-d defoliation interval across the defoliation hight ranging from 211.2 to 219.7 g/kg, and it was not different between the 60 and 90-d defoliation interval across the defoliation hight (255.0-258.1 g/kg and 230.3-236.0 g/kg, respectively). Defoliation hight did not affect (P > 0.05) the DM and OM in vitro digestibility. They were at the 90-d defoliation interval ranging from 680.2 to 706.8 g/kg and from 668.6 to 686.8 g/kg, respectively across the defoliation hight different. The DM and OM digestibility were not different (P > 0.05) between the 30 and 60-day defoliation intervals. It is concluded that when planted at low land of wet climate the combination of a 60-d defoliation interval and 1.5 m defoliation hight is an optimum cutting management in utilization of Indigofera sp as foliage for ruminant.

T3 (55% B. ruziziensis + 45% Indigofera sp.) all on DM basis. Feed (DM) was offered  daily at 3.5% BW. The content of CP in Indigofera sp is relatively high (258 g/kg DM), while the NDF (350.7 g/kg DM) and ADF (232.2 g/ kg DM) concentrations were low. The content of secondary compounds such as total phenol (8.9 g/kg DM), total tannin (0.8 g/kg DM) and condensed tannin (0,5 g/kg DM) were considerably low. The inclusion of Indigofera sp foliage in diets increased (P < 0.05) the DM, OM, CP, NDF and ADF digestibilities. The digestibility of DM (601,0 g/kg DM), OM (625 g/kg DM) and CP (699.0 g/kg DM) were highest in the T3 diets. DM intakes were greatest in the T2 and T3 diets (P < 0.05). Total gain increased 39, 78 and 85% in T1, T2 and T3 respectively, compared to that in the control diet. Daily gains were highest in the T3 (52.4 g) and T2 (50.5 g) diets, but feed efficiency was highest (P < 0.05) in the T3 diets (0,12). Feed efficiency were not different (P > 0.05) among the T0,T1 and T2 diets and ranged from 0.08 to 0.09. It is concluded that the foliage of Indigofera sp could be used as feed supplement to supply proteins with low tannin contents.

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
