This study was carried out to investigate the use of antibiotic in feed and medication programs and their effects on broilers Serum Cholesterol and Glutamic Oxaloacetic Transaminase (SGOT). The broilers were sampled randomly from four small-scale broiler producers (BP1, BP2, BP3, BP4) in Semarang regionCentral Java, Indonesia. Observed data comprising medication programs and the types of feed i...

This study aimed to investigate the effects of dietary zinc (Zn), environmental temperatures and Zn×temperature interaction on growth, feathering score and mineral composition of broilers. A total of 256 d-old Avian male broiler chicks were randomly allocated to a 4×2 factorial arrangement with four corn-soybean meal basal diets (containing 44 mg Zn/kg) supplemented with 0, 40, 60 mg/kg Zn (Die...

The present experiment investigated the impact of administrations lactic fermented turmeric, black pepper or a mixture both into diets on hematological parameters and intestinal ecology morphology broilers. Three hundred ninety two broilers were spread to T0 (control), T1 (feed administrated with 1% turmeric), T2 pepper) T3 turmeric pepper). Blood sampling was conducted at days 21 35, while day...

A series of 4 experiments evaluated effects of mash conditioning temperature from a pellet mill or expander on performance of broilers fed pelleted diets containing spray-dried plasma (SDP). All experiments utilized Ross x Ross 308 male broilers randomly assigned to their respective treatments (6 or 10 broilers/pen and 8 or 10 pens/treatment). Treatments in Exp. 1 consisted of a control (0% SDP...

Research with adult mammals has shown that the diet-induced thermogenesis (DIT) related to the oxidation of macronutrients has a negative feedback on feed intake (FI), depending on the nutrient considered: proteins are combusted first, then carbohydrates and finally fat, corresponding to their satiating ability. However, previous studies revealed no significant differences in DIT between broile...

This study was conducted to evaluate the pilot-scale production of microencapsulated in a 500-L fermenter using emulsion and gelation and to assess the effect of the products on the growth performance, antioxidant activity, immune function, and cecal microbiota in Arbor Acres broilers. A total of seven hundred 1-d-old male Arbor Acres broilers were randomly assigned to 7 dietary treatments with...

In this study, we profiled gene expression in chicken liver and screened differentially expressed genes in the Bai'er layers and fat line broilers. Birds were derived from the 14th generation of Northeast Agricultural University fat broiler lines and Bai'er layers. Chicken genome arrays were used to screen differentially expressed genes in liver tissue from the Bai'er layers and fat line broile...

Two trials were conducted to determine the effect of air velocity on feed and water consumption at a constant temperature of 27 C and a daily cyclic temperature of 22-32-22 C. Air velocity over the broilers was <15 or 120 m/min. These temperature and air velocity treatments were arranged in a 2 x 2 factorial design in eight environmental chambers, with two replications of each treatment. The ai...

In an attempt to determine the effect of dietary energy source on the quantity of abdominal fat in broilers, three levels of dietary animal fat (4, 7, and 10%) in isocaloric and isonitrogenous diets were fed in place of a carbohydrate energy source. Three trials were conducted. As dietary animal fat increased, the amount of abdominal fat in broilers increased under both a moderateand a high-tem...
