Abstract

The high concentration of sodium chloride (NaCl) in saline soils has negative effects on the growth ofmost plants. The experiment was designed to evaluate macro nutrient uptake (Nitrogen, Phosphorus andPotassium) of forage grasses at different NaCl concentrations in growth media. The experiment wasconducted in a greenhouse at Forage Crops Laboratory of Animal Agriculture Faculty, Diponegoro University.Split plot design was used to arrange the experiment. The main plot was forage grasses (Elephant grass(Pennisetum purpureum ) and King grass (Pennisetum hybrida)). The sub plot was NaCl concentrationin growth media (0, 150, and 300 mM). The nitrogen (N), phosphorus (P) and potassium (K) uptake in shootand root of plant were measured. The result indicated increasing NaCl concentration in growth mediasignificantly decreased the N, P and K uptake in root and shoot of the elephant grass and king grass. Thepercentage reduction percentage of N, P and K uptake at 150 mM and 300 mM were high in elephant grassand king grass. It can be concluded that based on nitrogen, phosphorus and potassium uptake, elephantgrass and king grass are not tolerant to strong and very strong saline soil.

Abstract

Eight bulls of Ongole Crossbred (OC) cattle with initial body weight (BW) of 297 + 26 kg (CV =8.75%) fed rice straw treated with urine (RU) (ad libitum) were divided into two groups (each fourheads) to determine the effect of concentrate feeding level on efficiency of eating behavior. The cattlewas given concentrate feeding composed of beer cake and rice bran to make 14% crude protein at 1%and at 2% BW for RUC1 and RUC2 group, respectively. Eating behavior was measured for 3x24 hoursand was performed twice at weeks 2 and 6 of the study. Data obtained were analyzed by t-test. Theresults showed that the level of concentrate feeding affected the intake of urinated rice straw (P<0.01)and daily BWGain (P<0.05), but the effect was not found (P>0.05) on DMI, length time for eating(196.5 vs. 221.5 min/d), length time for rumination (351.0 vs. 449.4 min/d), efficiency of eating time(37.21 vs. 37.67 gDM/min) and efficiency rumination time (21.43 vs. 18.50 gDM/min). This researchshowed that concentrate feeding at 2% BW did not alter the efficiency of eating time and ruminationcompared to 1% BW, although able to improve BWG of OC cattle.

Abstract

This study was aimed to explore the effects of Betaine-Homocysteine Methyltransferase (BHMT) gene polymorphisms on fatty acid traits and cholesterol in lambs. This study used a total of 147 blood samples for genotyping including 19 Javanese Fat-Tailed (JFT), 16 Javanese Thin-Tailed (JTT), 41 Composite Garut (CG), 35 Compass Agrinak (CA) and 36 Barbados Black Belly Cross (BC). A total of 61 rams as representative from five breed of sheep were selected for association study. Identification of BHMT single nucleotide polymorphisms was analyzed by PCR-RFLP method. Association of BHMT genotypes with fatty acid traits and cholesterol was performed by T-TEST. BHMT genotyping resulted into three genotypes (CC, CT and TT). Gene frequency of BHMT (g. 9947372 C>T) was in Hardy-Weinberg Equilibrium, excluding Javanese Fat-Tailed sheep. Association of BHMT genotypes with fatty acid traits resulted into a significant association (P<0.05) with C14:1, C17:1 and C18:0 fatty acids but not with cholesterol in sheep. SNP g. 9947372 (C>T) of BHMT gene might be a useful marker for selecting and producing sheep meat with desirable fatty acids.

Abstract

The objective of this study was to study the mineral status of Java thin-tailed (JTT) sheep grazed in Mijen-Semarang, Central Java. Six month old of male JTT sheep and paddock with field grass vegetation were used in the research. Fifteen male JTT sheeps were divided into three groups consisting of 5 heads per group, and grazing for 2 month (in early rainy season, late rainy season and dry season, respectively). The measured variables were feed consumption, digested organic matter, mineral (calcium, phosphorus, magnesium, copper, zinc) level in forage, feces, blood, and daily body weight gain. The data were analyzed by analysis of variance with one-way classification. Magnesium and zinc status of JTT sheep were adequate, whereas phosphorus status was deficient in all season. Calcium in early and late rainy season were deficient (7.37 and 7.86 mg/100 mL, respectively), whereas in the dry season was adequate (8.70 mg/100 mL). The copper deficiency was found in dry and late rainy season (with the Serum copper level was 0.62 and 0.51 µg/mL, respectively, and borderline in early rainy season (64.7 µg/mL). Serum copper in the late rainy season was lower (P<0.05) than it in early rainy season and dry season. There were seasonal variation of mineral status of Java thin-tailed (JTT) sheep grazed in Mijen agricultural area, Semarang, Central Java.

Abstract

The objective of this research was to improve beneficial value of cacao pod as sheep feedingredients comprising up to 50% total feed. This research was conducted in two stages. Stage 1 wascacao pod fermentation. Completely randomized design with 3x3 factorial patterns was used in thisstage, in which factor I was microbial inoculum dosage of 0%, 0.05% and 0.1% and factor II wasincubation period of 0, 3 and 6 days. Result demonstrated that six-day fermentation with 0.05%microbial inoculum could lower cacao NDF, ADF and theobromine. The optimum inoculum dosage andfermentation time from stage 1 was applied to stage 2. Stage 2 was rumen microbial fermentation test.This research administrated 3x3 of latin square design. In period I sheep were fed with CF0 (nonfermentedcomplete feed), in period II sheep were given CF 1 (complete feed containing fermentedcacao pod) and in period III sheep were given CF2 (fermented complete feed based cacao pod). Resultdemonstrated that pH value of sheep microbial liquid in treatment of CF0, CF1 and CF2 was in normalpH range and did not affect volatile fatty acids (VFA) and ammonia. In conclusion, supplementing up to 50% of feed with complete feed containing fermented or non-fermented cacao pod did not affect theprocess of rumen microbial fermentation.

Abstract

The aim of this study was to evaluate the effect of simvastatin (SIM) and L-carnitine (LC) additives and their interactions, on productive performance and carcass quality of broilers. For this purpose, a feeding trial was conducted, under 3×3 factorial design, using SIM at 0, 1 or 2 g/kg level and LC at 0, 150 or 300 mg/kg level in a basal-diet and originating a total of nine treatments: T1 (control-diet, 0/0), T2 (0/150), T3 (0/300), T4 (1/0), T5(1/150), T6 (1/300), T7 (2/0), T8 (2/150), and T9 (2/300). Feed intake was higher in T2 (4716 g), T7 (4722 g) and T9 (4698 g) than in T1 (4545 g; P<0.05) considering the last growing phase (35-42 days) or whole 42-day production cycle. An improvement of feed efficiency was also observed in T8 (1.64) and T9 (1.67) when compared to T1 (1.77; P<0.05), and these were mainly due to SIM × LC interactions (P<0.05). The LC influenced positively (P<0.05) the weight of eviscerated carcass, breast, drumsticks and abdominal fat, as well as plasma triglycerides level. This findings suggests that the combination of SIM and LC additives have a positive influence on growth performance and carcass traits of broiler chickens.

Abstract

This study was conducted to investigate the effect of different level of energy and crude fiber in diets containing sawdust on carcass quality of broilers. A total of 120 broilers were used for the research. The experiment utilized a completely randomized design in 2 x 3 factorial arrangement of treatments consisting of two dietary concentrations of energy and three dietary concentrations of crude fiber. Each treatment consisted of 4 replications (5 birds each) was reared during 35 days. The birds were housed in battery cages with ad libitum access to feed and water. During the experiment, feed intake, carcass yield, abdominal fat, blood LDL-cholesterol and HDL-cholesterol were measured. Data were subjected to the analysis of variance test followed by least significant difference test (LSD). Results showed that the diet with 3,100 Kcal/kg ME and 11% crude fiber significantly decreased feed intake, abdominal fat percentage, and blood LDL-cholesterol, but did not affect final body weight and the value of blood HDL-cholesterol and had the good value of carcass percentage. The diets containing sawdust with higher level of energy content decreased feed intake and the higher level of crude fiber decreased final body weight, carcass percentage and abdominal fat. Optimum broiler performance and carcass quality was obtained by diet formulated to contain 3100 Kcal/kg ME and 11% crude fiber.
