Abstract

The improvement in broiler chicken performance is currently thanks to the genetic selection, nutrition, maintenance management, and health and biosecurity programs that have succeeded in improving the maintenance performance of broilers.  Such rapid development in the cycle after hatching is undoubtedly also influenced by the embryo's development or the prenatal phase. Unlike other mammals, the process of breeding poultry has its characteristics where the process of embryonic development occurs outside the body of livestock or inside poultry eggs. Chicken embryos rely heavily on the nutrients inside the egg, which provide the energy and amino acid makeup needed for the metabolic needs of the growing embryo during the 21-day incubation process. Chicken embryos are susceptible to a lack of energy during the hatching process. This deficiency can result in weak embryos and, in more severe conditions, embryo death and failure to hatch. The nutritional needs of embryos during incubation can be added to the egg with the in ovo feeding technique. The in ovo feeding technique is a technique that allows the addition of outside nutrients injected into the egg during incubation for the developmental and metabolic needs of the embryo, as well as to improve the nutritional status of the egg.  Nutrition stimulation with in ovo feeding technique produces many benefits, such as increasing hatchability, hatching weight, immunity level, reduced bone system disorders, reduced morbidity and mortality after hatching, feed efficiency and weight gain.

Abstract

Proses penanganan dan perubahan mikroklimat yang dialami oleh DOC (Day Old Chick) selama proses transportasi mempengaruhi performa DOC. Penelitian ini bertujuan untuk menganalisis dampak jarak transportasi dan pemberian gula aren dengan konsentrasi yang berbeda terhadap kondisi DOC dan performa ayam broiler yang dipelihara hingga 28 hari. Jumlah sampel sebanyak 900 ekor DOC (9 boks). Penelitian ini menggunakan interaksi dua perlakuan. Perlakuan pertama yaitu dengan perbedaan jarak transportasi yang digunakan adalah 14 km (T1), 416 km (T2), dan 532 km (T3). Perlakuan kedua yaitu pemberian minum gula aren dengan konsentrasi yang digunakan adalah 0%, 5%, 10% dan 15% per liter air minum. Data performa pemeliharaan pada usia tujuh hari dan 28 hari dianalisis dengan rancangan acak pola faktorial (RAL Faktorial). Hasil penelitian menunjukkan konsumsi pakan, pertambahan bobot badan, dan mortalitas ayam usia tujuh hari dan 28 hari tidak berbeda nyata (P<0,05) pada interaksi perlakuan jarak transportasi dan pemberian gula aren. Pemberian gula aren dalam minum tidak menunjukkan pengaruh yang nyata tehadap parameter performa pemeliharaan selama 28 hari sedangkan jarak transportasi berpengaruh terhadap konsumsi pakan dan pertumbuhan bobot badan. Konsumsi pakan dan bobot badan tertinggi diperoleh pada perlakuan T3 dan T1. Oleh sebab itu, konsentrasi larutan gula aren merah sebaiknya diberikan maksimal 10% serta perlu dilakukan perbaikan kondisi kendaraan dan sistem perencanaan transportasi.

Abstract

Environmental thermal challenges may affect reproductive function and semen quality in male quail. This study aimed to evaluate the effects of Bandotan leaf extract on the fresh semen characteristics of male Japanese quail under heat stress conditions. Bandotan leaves were extracted using 96% ethanol by maceration and analyzed for proximate composition, iron (Fe) content, phytochemical compounds, and antioxidant activity based on the IC50 value. A total of 100 six-week-old male quails were randomly assigned to four treatment groups with five replications and administered Bandotan leaf extract through drinking water at doses of 0, 75, 150, and 225 mg bird⁻¹ day⁻¹. Environmental conditions were monitored using the temperature–humidity index (THI), and semen samples were collected from 20 quails, with one bird randomly selected from each experimental unit. The extract contained flavonoids, phenols, and tannins and showed moderate antioxidant activity (IC50 = 174.84 µg mL⁻¹). The afternoon THI was 32.24 °C. Bandotan leaf extract significantly affected semen pH, spermatozoa motility, and abnormalities (P<0.05). Semen pH increased from 6.5±0.26 in the control to 7.1±0.29 at 150 mg bird⁻¹ day⁻¹, while motility increased from 79.00±5.47% to 88.00±2.74% at 75 and 150 mg bird⁻¹ day⁻¹. Spermatozoa abnormalities decreased from 9.36 ± 0.39% in the control to 6.96± 0.34% at 225 mg bird⁻¹ day⁻¹. Spermatozoa viability and mass movement were not significantly affected. Further studies are needed to evaluate extract safety and in vivo antioxidant effects.
