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

This study was conducted to evaluate diets containing durian (Durio zibethinus Murr) seed meal (DSM) on the performance, nutrient retention and egg qualities of commercial layers. A total of 120 fifty two -week-old laying hens were distributed according to a completely randomized design in four treatments and five replications with six birds each. The treatments consisted of different levels of durian seed meals (control, 3% DSM, 6% DSM, and 9% DSM). Feeding diets containing durian seed meal had no significant effect (p > 0.05) on the feed consumption of laying hens at 58 wk of age. Inclusion of up to 6% DSM in formulated layer diets did not reduce egg production and nutrient digestibility, but reduced egg weight. No differences (p>0.05) were observed in egg calcium content, egg calcium mass, and yolk color score fed diets containing DSM. This study suggests that DSM could be incorporated up to 6% in laying hen diets without adverse effect on production performance, nutrient retention and egg qualities.

Abstract

The study was conducted to evaluate the effect of dietary supplementation of red tomato extract (RTE) on intestinal microflora, fat digestibility, body fat (meat fat mass, abdominal fat), and performances of male tegal duck. One hundred birds of male tegal ducks of 3 weeks old (initial body weight was 507.74±31.86 g) were randomly divided into 4 treatments with 5 replications (5 birds each) in a completely randomized design. Dietary treatments were basal diet without RTE as a control (T0), basal diet added with 0.10% RTE (T1), basal diet added with 0.15% RTE (T2) and basal diet added with 0.20% RTE (T3). Parameters measured were lactic acid bacteria (LAB), coliform, intestinal pH, fat digestibility, meat fat mass, abdominal fat, blood concentrations of malondialdehyde (MDA) and superoxide dismutase (SOD), body weight gain (BWG), carcass weight, feed consumption, and feed conversion ratio (FCR). Data were subjected to analysis of variance and continued to Duncan multiple range test when the treatment indicated significant (p<0.05) effect. Supplementation of RTE at higher level significanly (p<0.05) increased lactic acid bacteria (LAB), concentration of superoxide dismutase (SOD), carcass weight and body weight gain (BWG), while fat digestibility, meat fat mass, abdominal fat, malondialdehyde (MDA), intestinal pH, coliform counts and feed conversion ratio decreased (p<0.05), as compared to control. Feed consumption tended to decrease but not significant (p>0.05). In conclusion, feeding red tomato extract at a level of 0.20% (T3) can be categorized as effective in improving intestinal bacterial balance, body fat, increasing superoxide dismutase (SOD), an antioxidant enzyme, and performances of male tegal duck.

Abstract

The objective of the present study was to investigate the effect of Kleinhovia hospita L. extract (KE) on growth performance, intestinal condition and antioxidative status of broilers raised in high stocking density pens. A total of 370-day-old broiler chicks were randomly grouped into five groups with five replicates. The groups were T0 (chicks raised in normal density, 10 birds/m2; as a negative control), KE0 (chicks raised in high density, 16 birds/m2, without KE supplementation; as a positive control), KE0.25, KE0.5 and KE1 (chicks raised in high density with KE supplementation of 2.5, 5 and 10 g/kg, respectively). Based on the completely randomized design, the data were treated. Results showed that KE1 chicks had the highest (p<0.05) body weight (BW) at day 21 and 28. The T0, KE0 and KE2.5 chicks consumed more (p<0.05) feed than the other treatment groups. The KE0.25, KE0.5 and KE1 showed lower (p<0.05) FCR than the KE0 group. The KE0 chicks showed lower (p<0.05) carcass yield than the other groups. The KE0 had the highest (p<0.05) heart relative weight of all groups. The KE1 had the highest (p<0.05) small intestinal weight, cecum, colon and abdominal fat of any treatment group. Among the groups, crypt depth of the duodenum in KE0 was the lowest (p<0.05). There was no substantial effect of the treatments on the counts of coliform and lactic acid bacteria in the ileum of broilers. The superoxide dismutase (SOD) levels in KE0.5 and KE1 were higher (p<0.05) than those in T0, KE0 and KE0.25 groups. In conclusion, stocking in high density pens negatively af-fected the carcass yield of broiler chickens. Dietary KE supplementation was beneficial in improving FCR and antioxidant status of broiler chickens.

Abstract

Encapsulated cardamom waste extract (ECWE) contains flavonoids with antibacterial and antioxidant properties that may enhance broiler health and performance. This study evaluated the effects of ECWE as a phytobiotic on broiler intestinal microbiota, pH, H/L ratio, lymphoid organs, and performance. A total of 200 unsexed Ross broilers (8 days old) with an average body weight of 215.08±5.1 g/bird were assigned to five dietary treatments: T0 (control), T1 (0.02% ECWE), T2 (0.04% ECWE), T3 (0.06% ECWE), and T4 (0.08% ECWE). Results showed that 0.08% ECWE significantly increased lactic acid bacteria (LAB) populations, lymphoid organ, and broiler performance. The increase in LAB given 0.08% ECWE is more effective in helping to reduce intestinal pH and to minimize the growth of pathogenic bacteria that can interfere with chicken digestion. In addition, the antioxidant properties in ECWE had a positive effect on the development of lymphoid organs, especially the thymus. It is concluded that ECWE supplementation at 0.08% was the most effective in improving digestive tract health and optimizing broiler performance.
