Transportation to the slaughterhouse is a series of processes that can cause high levels of stress in broilers. Heat stress will increase if the distance between the farm and the slaughterhouse is far. One of the solutions to overcome heat stress due to transportation is to do watering a few minutes before the transportation so that the broilers are still able to maintain their homeostatic conditions. This study aims to determine the effect of watering methods before transportation with different distances on the haematological, hormonal, and quality status of broiler chickens. This study was arranged based on a factorial randomized block design (RAK). A total of 54 broilers of the Cobb strain aged 35 days were divided into 2 treatments, namely; without watering (P0) and watering (P1). Chickens in each treatment were transported to the poultry slaughterhouse with 2 different distances; 30km (J1) and 60km (J2), as well as 1 control treatment (without transport) (J0). Watering is done just before the transportation process. The results showed that the transportation distance increased the yellowness value (b*) of the breast meat, decreased the brightness value (L*), and increased the pH of the broiler thigh meat (P0.05). Hematocrit values, hemoglobin levels, and concentrations of the hormone triiodothyronine (T3), other meat color components, as well as the pH of the breast meat, did not change significantly, both in terms of watering, distance traveled, and the interaction between the two (P0.05). The solution of water spraying before transportation on different distances could not restore the hematology and hormonal status, as well as the meat quality of the broiler. However, the decline in meat quality was shown in transported broilers.
The aims of this study was to determine the effect of addition encapsulated liquid smoke in drinking water to relative of weight life, carcass, organ and chemical component of broiler meat. Broilers were grown to 30 days of age on ad libitum diets and addition of liquid smoke encapsulated in drinking water were given in 14th day every 3 days ad libitum. One hundred Day Old Chicks (DOC) were randomly assigned into 5 treatments and 4 replications, each replicate consisted of 5 birds. The treatments started at 14th day, consist of P0 = control, P1= commercial antibiotic (acidal™) and liquid smoke encapsulated (P2 = 0.5 %, P3=1.0%, P4=1.5%). The result showed that addition of encapsulated liquid smoke to drinking water had significant effect (P<0.05) on broiler life weight, and carcass weight. Meanwhile, there was no significant effect (P>0.05) on percentage of carcass, liver, heart and gizzard. The result of broiler fat meat show at 0.5-1.0 % level addition of liquid smoked encapsulated have same effect as commercial antibiotic, meanwhile the addition of liquid smoked encapsulated have no effect to pH and cholesterol of broiler meat.
<p>This study aimed to determine the effect of <em>in-ovo</em> injection of L-arginine on hatchability, chick quality, performances, and muscle histology of native chicken. <em>In-ovo</em> injection was carried out on the 10th day. A total of 375 fertile eggs with an average weight ranged 39-43 g were grouped into 5 treatments. The first treatment was without injection (negative control), the second treatment was injection of NaCl solution 0.9% (positive control), the third treatment was injection of L-arginine solution 0.5 g per 100 ml of NaCl 0.9% (0.5%, m/v) The fourth treatment was injection of 1.0 g L-arginine solution per 100 ml of NaCl 0.9% (1.0%, m/v), and the fifth treatment was injection of 1.5 g L-arginine solution per 100 ml of NaCl 0.9% (1.5%, m/v). The injection was carried out at the pointed area of the egg in a vertical position (pointed below, blunt above). The Injection was carried out with a depth of 10 mm from the eggshell using an automatic injector. The results showed that all treatments produced the same hatchability. <em>In-ovo</em> injection of L-arginine has a beneficial effect on chick quality and post-hatch performance, the concentration of L-arginine solution used did not cause embryo death. <em>In-ovo</em> injection of 0.5% L-arginine increased hatching weight, weekly body weight, muscle mass, and myofiber size.</p>
To get quality eggs, breeders can try traditional ingredients as an alternative to caring for chickens. Because traditional plants are also considered to have efficacy as antibiotics. In getting positive results, it is necessary to test plant species that are in accordance with the standards of chicken needs. In this case, it has been determined through the feasibility of herbal medicines such as herbs and papaya leaves as Antibiotic Residues and improving egg quality. The results showed that the addition of papaya leaf extract in drinking water (P2) could increase the thickness of the shell, the addition of papaya leaf extract in combination with herbal medicine (P3) could increase the value of the egg yolk colour index, and there was a tendency to increase the colour of the shell in the P2 and P3 treatments. In addition, there were no antibiotic residues in chicken eggs in all treatments which indicated that the eggs were healthy and safe for consumption.
