Abstract

Duck is one of the commodities that contribute to the national livestock production and Central Java is home to the fourth biggest duck population after West Java, South Sulawesi and East Java. The 2019 egg production in Central Java was 36.174 tons or 11.3% of the total egg production nationwide. Accordingly, it is important to investigate the effect of environmental factor, total number and age of ducks on egg production in Central Java. Specifically, this study aimed to observe the effect of region on egg production and feed conversion ratio (FCR) and the total livestock (chicken), age (month), stocking density (ducks/m2), internal housing temperature (oC), and humidity (%) on Hen day production/HDP. A survey engaging purposive random sampling was conducted on the population of duck farming in Central Java especially Tegal, Pemalang and Brebes districts. The data were subjected to General Linear Model (GLM) and a regression-correlation analysis using an SPSS program. The result showed that region significantly affected hen day production (HDP) but did not affect FCR. Housing temperature affected HDP by 14.9% and the higher the temperature, the lower the HDP. Duck age affected HDP by 11.7%, and the older the ducks the lower the egg production. Duck population, stocking density and humidity did not significantly affect egg production. Conclusively, duck egg production (HDP) is significantly affected by temperature inside the housing and the duck age.

Abstract

This study was aimed to evaluate the use of safflower oil (Carthamus tinctorius L) and inositol on the digestive profile of male Sentul chickens. A total of 182 Sentul chickens aged 17 weeks were reared up to 23 weeks in 91 units of battery cage (6 chickens/unit). The research was conducted in a Completely Randomized Design (CRD) with nine treatments and three replicates (6 chickens/replicate). The research treatments were R0 = control/ basal feed + 0% Safflower and 0% Inositol; R1 = Basal feed + 0.5% Safflower oil; R2 = Basal feed + 1.0% Safflower oil; R3 = Basal feed + 0.5% Inositol; R4 = Basal feed + 1.0% Inositol; R5 = Basal feed + 0.5% Safflower oil and 0.5% Inositol; R6 = Basal feed + 0.5% Safflower oil and 1.0% Inositol; R7 = Basal feed + 1.0% Safflower oil and 0.5% Inositol; R8 = Basal feed + 1.0% Safflower oil and 1.0% Inositol. Basal feed was composed of corn, rice bran, soybean kernel, fishmeal, palm oil, calcium carbonate (CaCO3), topmix, lysine, and methionine, as well as safflower oil (Carthamus tinctorius L) and inositol. The measured variable consists of digestive profile (the percentage of intestine weight, digesta, proventriculus, gizzard) and intestine length, crypt depth, the width and length of intestinal villi, Intestinal histology profile. The data were subjected to a statistical analysis of variance (ANOVA) continued with an Honestly Significant Difference test (HSD). The result showed that incorporating safflower oil (Carthamus tinctorius L) and inositol into feed did not significantly affect (P>0.05) the digestive profile of Male Sentul chickens. Conclusively, safflower oil and inositol up to 1% in the feed are safe for male Sentul chickens without interfering with the performance of digestive organs because it produces relatively similar intestinal weight and length, crypt depth, as well as the length and width of intestinal villi.

Abstract

The study investigated the productivity of smallholder broiler farming with and without AGP to identify the difference between the utilization and absence of antibiotic growth promoter (AGP) incorporated into the broiler feed based on production (feed efficiency and cumulative performance index), economy (farming capacity and income), and socio-demography (farmers’ education background, age, farming experience, and farming motivation) in Central Java Province. The study was conducted through a survey of broiler farmers in one partnership company. The data analysis included analysis of variance based on a stratified GLM (general linear model) and correlation analysis. The result did not identify significant differences in the production aspects in either AGP or non-AGP farming, among different regencies, and farm size. In 2018, when farms stop using the AGP, the farm production is better than in 2017 when the AGP was used. Based on the economic aspect, the AGP and non-AGP administration did not affect farming capacity and income. The socio-demographic aspect showed that education significantly affected the success of broiler farming, while farmers’ age, farming experience, and farming motivation did not affect the production of broiler farming. The result of correlation analysis showed that education background contributed to feeding efficiency and cumulative performance index. The conclusions are (1) broilers fed with either AGP or non-AGP containing feed showed relatively similar performance, (2) the government policy on the prohibition of AGP does not contribute to the decrease of farmers’ income and (3) the demographic aspect affecting the success of the broiler farming business is the farmers’ education level.
