Abstract

This experiment aimed to determine the nutrient digestibility of Bligon and Kejobong goats fed by king grass and peanut straw. The sample used was 6 to 8 months of five male Bligon goats, and five male Kejobong goats with the initial body weight of 15 to 20 kg and placed in separated metabolism cages. The diet and water were supplied ad libitum. This experiment was done in 14 days of adaptation period and seven days of the collection period. In the collection period, samples of feed, refusal feed, and feces 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 nutrient (TDN). The data obtained were subjected to a T-test analysis. Results showed that nutrients intake, digested nutrient as well as nutrient digestibility of Bligon and Kejobong goats were not significantly different. However, Kejobong goats had EE and CP intake of 15.42% and 14.02%, digested DM, OM, and NFE of 16.29%, 15.71%, and 13.93% respectively, as well as NFE digestibility 4.37% higher than those Bligon goats (P< 0.05). Therefore, there was no difference in nutrient intake, digested, and digestibility of nutrients in Bligon and Kejobong goats fed by king grass and peanut straw. However, Kejobong goats appeared to have higher EE and CP intake, as well as digested and digestibility of DM, OM, and NFE than Bligon goats.

Abstract

Yoghurt is a well-known fermented dairy product which produced using a combination of lactic acid bacteria (LAB) of Streptococcus thermophilus, Lactobacillus bulgaricus and L. acidophillus as fermentation starters. Cow milk is usually used as a raw ingredient. The LAB-based local yoghurt starter (S. thermophilus RRAM-01 (ST), L. bulgaricus RRAM-01 (LB) and L. acidophilus IIA-2B4 (LA)) were previously isolated from milk and meat, nevertheless had not been extensively attempted to be used in yoghurt production. This study aimed to evaluate the characteristics of cow and goat milk based yoghurt produced by using a single local strater of S. thermophilus RRAM-01 (ST) or L. bulgaricus RRAM-01 (LB) or L. acidophilus IIA-2B4 (LA). The yoghurts were produced through addition of the starter (3% v/v each) with 1010 CFU mL-1 of initial population, and then fermented at room temperature for 24 hr.  The result revealed that initial population of LAB in goat’s milk yoghurt fermented by ST or LB were significantly higher than that of by LA. Yet, after 24-hour of storage at room temperature, the total population of LA increased and reached final population which was higher than LB or ST. Meanwhile, cow’s milk yoghurt fermented by LB had the highest population of at the initial day (D0), while after fermentation the highest population were observed on LB or LA cow’s milk yoghurt. Overall goat’s milk yoghurt had significantly lower pH values than the cow’s milk yoghurt. These were accompanied by higher the total titrated acid (TTA) of goat’s milk yoghurt than that of cow’s milk yoghurt. Based on pH and TAT values, it was found that  ST bacteria produced significantly higher total acidity goat’s milk yoghurt, followed by LB and LA. However, the type of culture had no effect on total acidity of cow's milk yoghurt.

Abstract

The study aimed to describe lactation characteristic of Etawah Crossed Breed goats raised under intensive management. The study located in BBPTU HPT Baturraden, Purwokerto, used 27 female pregnant goats, at 24 to 27 months old. The goats were managed followed standard operating procedure of the research institute. The data consisted of body size and body weight, colostrum and milk yield, lactation period and reproductive performance. The results showed the average of daily milk yield, lactation period, total milk and colostrum production in first lactation were 960±340 mL/day, 157±41 days, 114,720±68,900 mL and 415±240 mL/day. The proportion of monthly milk production from initial lactation to dry off were 21.27, 22.17, 20.18, 17.29, 12.52, 9.13, and 5.65% of total lactation yield, respectively. Peak production ranged from first to second months of lactation, the highest was in the week 4th, averaged of 1080 mL/day. Production persistency was 66.39%. The rate of increase toward peak was 5.60%/week and rate of decline from peak was -3.92% of milk yield in the previous week. Trend equation of lactation curve was Y = 8412.7 –233.65 x. Means period of postpartum mating, service per conception and body condition score were 88.7±39.2 days, 1.2 and 3.45, respectively. There was no correlation between postpartum mating, body condition score and milk production. The study concluded that Etawah Crossed Breed goat under intensive management had short lactation period, early peak production, low persistency. The dry period was estimated 3 months and pregnancy occurred after peak production.

Abstract

The present study was to evaluate the effects of nano-encapsulated Phaleria macrocarpa fruit extract (NEPM) in drinking water on the digestive organs and carcass characteristic of broiler chickens. A total number of two hundred male broiler chicks were randomly divided into five treatments with four replicates, each replicate contained ten chickens. Broiler chickens have received a basal diet supplemented with or without experimental treatments. Five experimental treatments were: control diet (T0; negative control), diet with tetracycline (T1; positive control), diet with 2.5% of Phaleria macrocarpa fruits extract (T2),  diet with 2.5% NEPM (T3), and diet with 5.0% NEPM (T4). The diets were based on yellow corn and soybean meal and contained 20.44% crude protein, 2,917.47 kcal/kg metabolizable energy, 0.84% Calcium, and 0.51% available Phosphorus. On the 35th day, one bird from each replicate pen was slaughtered. Carcass characteristics and weights of digestive organs were measured. Data were statistically analyzed using ANOVA in a completely randomized design. The orthogonal contrast test was used to separate the mean when the P-value was less than 5%. Results showed that the use of nano-encapsulated Phaleria macrocarpa fruits extracts up to 5.0% in the diet did not give any significant effect on the carcass, digestive organs, heart and liver weights of broiler chickens. It can be concluded that the supplementation of Phaleria macrocarpa fruits extracts whether nano-encapsulated or not, did not affect carcass weight, weights of digestive organs and weights of the heart and liver of broiler chickens.

Abstract

The purpose of this research was to assess the reproductive performance of beef cattle based on different production systems. Survey research was carried out in Margasari Subdistrict, Tegal Regency, Central Java Province, in 13 farmer groups (a total of 188 breeders and 557 beef cattle) who took shelter in the SPR Program The qualitative and quantitative design framework is used to obtain comprehensive data. The questionnaire was used to get data and respondents determined by census method. SPSS software is used to analyze data. The results showed that 38.46% of farmer groups implemented a crop-livestock-system (CLS), 30.77% of farmer groups implemented a livestock-forestry system (LFS), and 30.77% of farmer groups implemented a crop-livestock-forestry-system (CLFS) in producing beef cattle. The results of the present study were significantly (P<0.05) there were differences in each reproductive performance parameter (BCS, S / C, CR, CI, and CC), which was observed in each beef production system (CLFS, CLS, and LFS). The results of this study also provide an overview of the simultaneous effects on the application of the production system to the reproductive performance of beef cattle. Although there has been certain variation between the production systems, the reproductive performance of the observed beef cattle has not been satisfactory. Improving nutrition management in cattle is needed to realize successful reproductive performance.

Abstract

Inherent thermal adaptation in livestock is an important economic trait that cannot be overlooked, most especially in animals reared in sub-optimal thermally stressful environments. The present study explored the possibility of using multifactorial discriminant analysis (DA) to separate two duck genera {Muscovy and Common (Mallard) ducks) and their hybrid (Mule ducks) to distinct genetic groups using physiological, haematological and biochemical parameters. Data were collected after exposure of ducks to solar radiation for 90 minutes (12.00 – 13.30 hours). The result of analysis of variance indicated that genotype significantly (P<0.05) affected heamoglobin (Hb), basophil (Bas), total protein (TP), albumin (Alb), globulin (Glb), skin temperature (SKT), respiratory rate (RRT), panting rate (PTR) and rectal temperature (RTC). Stepwise DA revealed that PTR, RRT, Bas and TP in descending order were the most important parameters discriminating the three duck genotypes. The result of cross validation showed that 71.00%, 97.30% and 50.00% of Muscovy, Common and Mule ducks were correctly classified in their expected genetic group respectively. The Euclidean distance between the duck genotypes indicated that longest distance (86.507) was between Muscovy and Common (Mallard) ducks while shortest distance (12.415) was between Muscovy and Mule ducks. The results are applicable in breed adaptation studies, management, conservation and improvement programmes.

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

This research set out to compare the physical and microstructural characteristics of kefir made of milk, colostrum, and milk-colostrum mixes at various proportions. Kefir was made by adding kefir grains to 100% milk (P0), 80% milk + 20% colostrum (P1), 60% milk + 40% colostrum (P3), 40% milk + 60% colostrum (P4), 80% milk + 20% colostrum (P5), and 100% colostrum (P6). Fermentation was allowed under room temperature for 24 hours. The characteristics observed were color values, viscosity, pH, water holding capacity (WHC), syneresis, and microstructure. The result showed that the color of kefir (L* value, lightness); (b* value, yellow-blue), (a*, red-green), and whiteness index (WI) was significantly affected by raw materials. The viscosity of kefir was also affected by the raw materials (p<0.05), in which the kefir made from a mix of 80% milk and 20% colostrum showed the highest viscosity (1524.20 m.Pa.S). However, other characteristics such as pH, WHC, and syneresis were not significantly affected by raw materials. The microstructure of kefir made from 20 to 40% colostrum showed a string and compact protein tissues, while that made from 80 to 100% colostrum showed a clumping gel and concentration dominated by protein and fat tissues.  This study demonstrated that milk kefir produced from milk-colostrum mixes posses a yellowish color (b*), low whitenes index, negative a* value, low lightness, whereas kefir made from 100% colostrum showed slightly greenish with low lightness level. Kefir with highest viscosity was produced from combined 80% milk and 20% colostrum. The microstructure of kefir produced from mixes with 40% and 60% colostrum showed a strong, tight, and compact microstructure of protein tissues.

Abstract

This study was designed to determine the intestinal characteristics and nutrient retention of broiler chickens subjected to different protein regimes supplemented with betaine. Four experimental diets were formulated, consisting of two basal diets containing 20% and 23% crude protein (CP), both with and without betaine supplementation at the level of 0.14%. The diets were applied to 180 broiler chickens that were randomly allotted to 2×2 factorial arrangement with five replicates of nine chickens each. The diet with 20.0% CP generated better small intestine characteristics than the diet with 23.0% CP as indicated by the longer ileum and total small intestine length (P<0.05). This improvement was associated with lessened CP excretion and improved dry matter (DM) and CP retention (P<0.05) in the birds fed 20% CP. Furthermore, dietary betaine supplementation enhanced the ileum, total small intestine length, villus height, and villus-to-crypt ratio (P<0.05), indicating a greater surface area for nutrient absorption. This enhancement was reflected in the reduction of DM and CP excretion and improvement in DM and CP retention in the betaine supplemented group (P<0.05). Therefore, we conclude that feeding a diet of 20% CP with betaine supplementation improved the small intestine characteristics and nutrient retention of broiler chickens.
