Abstract

This research was aimed to evaluate the effect of the level of cattle reticulum meal as cholesterolsource in duck feed to accelerate molting period and post-molting re-laying process of Tegal duck.Experimental method was administered to sixty female Tegal duck aging 68 weeks old. Each treatment,comprised 3 layers with 5 repetitions, were cattle reticulum meal in feed (K), consisting of K0= 0%(control), K1 = 1.43% (equal to 0.37 g cholesterol), K2 = 2.86%, and K3 = 4.29%. The observed variableswere molting period, re-laying period, blood cholesterol level, and progesterone hormone level. Datawere analyzed by analysis of variance based on Completely Randomized Design followed by HonestlySignificant Difference Test. The result demonstrated that level of cattle reticulum meal significantlyaffected (P<0.01) molting period, re-laying period, blood cholesterol and progesterone level. It wasconcluded that 1.43% cattle reticulum meal could accelerate molting period and 2.86% cattle reticulummeal could accelerate re-laying.

Abstract

The study was aimed to analyze the on-farm agribusiness subsystem approach at farm household, to analyze beef cattle production influencing factors and to analyze economic efficiency of beef cattle farm. The method use for research was survey method at Wirosari District and Purwodadi District, Grobogan Regency as research location. Each district was determined two villages to obtain data from respondent. Quota sampling method was use for determination the number of beef cattle farm household without a counting of population as a sampling frame. The number of respondent for each village was 20 farmers, so the total respondent was 80 farmers. Data were analyzed descriptively for on farm sub-system agribusiness approach, multiple linear regression and economic efficiency. The research result showed that the on-farm agribusiness subsystem was on moderate to good condition, the influencing factors of production were breed, forage, concentrate, health, reproduction, labor, year of farming and agribusiness implementation. The value of reproduction efficiency was 8.975 higher than 1, it was not efficient. The efficiency of farm scale, forage, concentrate, health and labor were 0.352; 0.128; 0.0148; 0.0235 and 0.0834 respectively less than 1, and it had not been efficient yet. The conclusion of research was the agribusiness implementation in beef cattle farming was in moderate and good criteria and gave the benefit to farmers. Production factors of farm scale, forage, concentrate, health, reproduction, labor, years of farming and agribusiness implementation were influence to the beef cattle production. The efficiency of farm scale, forage, concentrate, health, and labor on the beef cattle farm were not been efficient yet, while reproduction became an inefficient production factor.

Abstract

The aim of this research was to determine the eating behavior of sheep which fed at day and/or night period. Twelve ram average body weight 20.65 + 1.89 kg, CV = 9.15%, and age ranged from 12 to 18 months were used in this study. Rams were daily fed pelleted diet at 5% of body weight (BW) in 100% dry matter base. Animals were assigned to Completely Randomized Design and divided into three groups for different feeding time treatments. The treatments were day feeding time (feeding allowed from 0600 to 1800; T0618), night feeding (from 1800 to 0600; T1806) and whole-day feeding (24 h; T0606), respectively. Parameters observed in this study were duration of eating, rumination, rest, standing and laying activity (minute/day), dry matter intake (DMI, g/day) and eating speed (g/minute). Collected data were analyzed using ANOVA with F-test and if significantly was found were then analyzed with Duncan test. The results showed that eating duration (89.71 min/day) and DMI (1034.53 g/day) on T1806 were significantly lower (P<0.05) than T0618 (117.78 min/day; 1208.75 g/day) and T0606 (127.5 min/day; 1281.63 g/day) but, the other observation of ruminating, rest, standing and laying duration and eating speed were found not significantly different in the all treatments. It can be concluded that feeding at night period can reduce eating time significantly compared to feeding during the day period or 24 hours a day, although it results in decreasing feed consumption.

Abstract

The aim of this study was to find out the influence of vitamin-mineral supplementation ondigestibility and rumen fermentation in Bali cattle. The randomized block design with 4 treatments and 4replications were used in the research. In this study was used 16 Bali cattle with body weight around295.31+23.07 kg. Rations used in the treatments were Treatment A (control): rice straw ad libitum pluscommercial feed; Treatment B: Treatment A ration plus 0.2% vitamin-mineral in commercial feed;Treatment C: Treatment A ration plus 0.3% vitamin-mineral in commercial feed, and Treatment D:Treatment A ration plus 0.4% vitamin-mineral in commercial feed. Parameters measured were nutrientdigestibility, rumen metabolites and urinary allantoin. The results showed that supplementation ofvitamin-mineral at 0.2 - 0.4% in commercial feed did not increase the digestibility of dry matter, organicmatter, crude protein and crude fiber, except for dry matter and organic matter digestibilities at 0.2%supplementation (p<0.05). However, the vitamin-mineral supplementation increased concentrations ofpartial VFA and ammonia as well as for methane gas production, except for VFA and ammonia at 0.4%level. Vitamin-mineral supplementation at 0.2-0.4% level did not affected pH value of rumen fluid andurinary allantoin.

Abstract

Research on fermentation time and the addition of milk powder to egg albumen is still limited. The purpose of this study was to determine the antioxidant activity and chemical characteristics of fermented egg albumen using different levels of full cream milk powder and different microbial fermentation times. This study used a completely randomized factorial pattern design, 4 x 5 treatments with 4 replications. Research materials include egg albumen, full cream milk powder and mixed Lactic Acid Bacteria (L. bulgaricus, L.achidopillus, and Streptococcus thermopillus). The research treatments were the addition of powdered milk in different level (%) including, 0, 2, 4 and 6. Fermentation times were 0, 12, 24, 36, and 48 h, respectively. The results showed that the addition of powdered milk in different level and fermentation time had no significant effect on the antioxidant activity. The addition of different-level powdered milk was not significant on the glucose content and total protein, but it was very significant (P<0.01) on water content. The fermentation time had a very significant effect (P<0.01) on glucose levels and total protein, but it had no significant effect on the water content of albumen fermentation. Antioxidant activity did not change during the fermentation time and the addition of different-level milk powder. The 24 h fermentation time could reduce the total protein and glucose levels of egg albumen. Adding 2% milk powder could reduce the water content of egg albumen fermentation.

Abstract

An experimental study was carried out to assess the effect of diet quality on productivity and bodycomposition of Kacang goat. Fifteen male Kacang goats weighing 14.28 ± 3.36 kg (CV = 23.55%) weredivided into 5 groups based on body weight. The experimental design used in this study wasRandomized Block Design (RBD) with 3 treatments of dietary protein and total digestible (TDN)contents (T1= diet with 9.20% protein and 54.67% TDN; T2= diet with 11.6% protein and 58.61%TDN; T3= diet with 18.33% protein and 65.23% TDN). Parameters observed were feed intake, drymatter intake, crude protein intake, TDN intake, live weight gain (LWG) and body composition ofKacang goat. The results showed that feed quality did not significantly affect (P>0.05) dry matter intakeand body composition, but significantly affect (P<0.05) protein intake, TDN intake and LWG. It can beconcluded that the higher quality diet resulted in higher productivity, but the higher quality diet was notaffect body composition of Kacang goat, except body fat gain (%).

Abstract

The objective of this study was to determine histomorphological change of seminiferous tubules, sperm quality and testosterone level after administration and cessation of pegagan extract. The research used 4x2 factorial complete randomized design, the first factor was dose-administration duration and the second factor was cessation length of pegagan extract. Parameters consisted of degree of spermatogenesis, sperm quality (motility, concentration and abnormality), and testosterone level. The data were processed using analysis of variance and Duncan’s test. Results showed that there was no interaction between dose-administration duration and cessation length. There was no significant difference of dose-administration duration of pegagan on degrees of spermatogenesis, sperm motility and testosterone level. Cessation length did not significantly affect degrees of spermatogenesis, sperm motility, and testosterone level although these results indicated that cessation of pegagan extract for 12 days increased degrees of spermatogenesis and sperm motility, indicated the antifertility potency of pegagan extract. In conclusion, Pegagan extract has potency as anti-fertility agent although the degree of spermatogenesis, sperm quality and testosterone levels were still in the normal range for the reproductive process and not irreversible, and pegagan could be explored as an reversible anti-fertility agent.

Abstract

This study was carried out to investigate the effect of different levels of Chlorella sp. in the form ofmeal administrated in the diet of broilers throughout their life upon FA profile of the breast muscle,mucosal secretory IgA (sIgA) concentration and production index (PI) of broiler. Allotted in 18 pens, thetotal of 90 Ross day old chicks were assigned in completely randomized design by 3 of dietarytreatments (T1: control (basal diet without enrichment of Chlorella sp.); T2: basal diet enriched with 5-gChlorella sp./kg feed; T3): basal diet enriched with 10-g Chlorella sp./kg feed. At d-36, skinless breastmeat was collected for FA determination. Practical standard of vaccination was performed to activateantibodies production and at d-36 gut mucosa was collected for sIgA analysis. Chlorella sp.administration had no significant effect (P>0.05) on the FA profile of breast muscle, mucosal sIgAconcentration and producton index of broiler. In conclusion, the level and ratio between n-3 to n-6polyunsaturated fatty acids (PUFA) as well as the nature of dietary PUFA source determine tissue PUFAcomposition. Beside through eicosanoid, Chlorella sp. may affect mucosal sIgA production throughcytokines mediated effect. Although Chlorella sp. administration does not improve the production indexof broiler, this treatment may produce broiler meat with lower fat content.

Abstract

The study investigated gut ecology and morphology of the Indonesian indigenous crossbred chickens (IICC) supplemented with the combination of formic acid and Saccharomyces cerevisiae. Two hundreds day-old IICC were distributed to T0 (control diet), T1 (T0 + 0.2% formic acid), T2 (T0 + 0.3% S. cerevisiae), T3 (T0 + 0.2% formic acid and 0.3% S. cerevisiae). Excreta was collected at week 8, while intestinal ecology and morphology were determined at week 9. In duodenum, T3 chicks showed higher and wider (P<0.05) villi. The T2 and T3 chicks showed deeper (P<0.05) crypt than that of T0. The jejunal villi was higher (P<0.05) in T3 than in T0. The T3 chicks had deeper (P<0.05) crypt compared to other groups. In ileum, the villi height was lowest (P<0.05) in T0. The crypt was deeper (P<0.05) in T3 than in other. Crude protein digestibility coefficient was highest (P<0.05), while fecal protein was loswest (P<0.05) in T1 than in other groups. Compared to T0, the treated IICC showed higher (P<0.05) weight gain and feed intake with T3 had the highest gain and intake but gain:feed rasio was the lowest (P>0.05). IIn conclusion, the inclusion of formic acid and S. cerevisiae in diets improved intestinal ecology and morphology. The IICC chickens fed with formic acid and S. cerevisiae exhibited improved growth performance and nutrient digestibility.
