This study investigated the effects of egg storage duration prior to incubation on performances of Arab Chickens during the first week post-hatch. A total of 100 day-old-chicks were distributed among 20 experimental units, each representing a different egg storage duration before incubation (1, 4, 7, and 10 days) with five replicates. There were five birds of each replicate totaling 25 birds per treatment. The variables examined in this study included the growth performance of Arab Chickens during the first week post-hatch, specifically the initial body weight, final body weight, body weight gain, feed intake, water intake, feed conversion ratio, and water conversion ratio. The findings of the study revealed that egg storage duration prior to incubation did not significantly affect (P>0.05) feed intake, water intake, and water conversion ratio. Storing eggs for up to 4 days did not result in any adverse effects (P>0.05) on initial body weight, final body weight, body weight gain, and feed conversion ratio. However, eggs stored for 7 days or longer exhibited a significant reduction (P

This study was aimed to analyze the physiological characteristics including respiratory rate, rectal temperature, and heterophil-lymphocyte (H:L) ratio of Sumatra’s organic chicken (SOC) that was raised in cool and hot climate regions. One-hundred-and-eighty-seven male and female SOC aged about 6 months were taken from cool and hot climate regions in Sumatera Island. Regions with cool climate were represented by highlands in West Sumatera including the subdistrict of Tilatang Kamang, Canduang, and East Padang Panjang. Regions with hot climate were represented by lowlands in Riau Province including the subdistrict of Bunga Raya, Lirik, and East Kampar. Samples of SOC were collected from farmers where the distance of sampling was about 500 m. Measurements were taken on respiratory rate, rectal temperature, and heterophil-lymphocyte ratio. Data was analyzed by t-test. The result showed that the respiratory rates of SOC in hot climate regions were higher than the ones in cool climate regions, the rectal temperatures of SOC in hot climate regions were lower than the ones in cool climate regions and there was no difference between the Heterophil:Lymphocyte ratio of SOC in hot climate and in cool climate regions.

This meta-analysis was conducted to investigate the effect of dietary propolis supplementation on broiler performance, carcass characteristics, and nutrient digestibility evaluated at the starter and finisher phases. An online literature search was conducted using scientific platforms of Science Direct, PubMed, and Google Scholar to identify the studies utilizing propolis as dietary supplementation in broiler chickens. A total of 39 publications comprising of 58 experiments met the inclusion criteria. A mixed model procedure for meta-analysis was performed, considering the studies as a random effect and levels of propolis as a fixed effect. Regression analysis suggested that average daily gain (ADG), body weight, and average daily feed intake (ADFI) at starter and finisher phases were quadratically affected by supplementing propolis in the diet (p

The purpose of this study was to determine reproductive efficiency, population dynamics, natural increase and estimated output of the Kuantan cattle in the Kuantan Singingi Regency, Province of Riau, Indonesia. A total of 311 Kuantan cattle and 99 Kuantan cattle farmers were used in this study through a survey study. Respondent samples were taken from seven districts. Data sampling using purposive sampling with survey methods. Data collection was carried out by interviewing farmers and observing and was analyzed descriptively. Parameters measured were reproductive efficiency, natural increase, estimated output and population dynamics of Kuantan cattle. Results showed that the reproductive efficiency of Kuantan cattle was 1.04%, natural increase 5.14%, the balance of male and female 1: 5, the value of male NRR 50% and female NRR 100.56%, total cattle out 18.69% and total incoming cattle 18.69%, output value 48.88% and estimated population dynamics 2.85%. In conclusion, Kuantan cattle reproduction has not been efficient with the natural increase of the Kuantan cattle was very low, and the replacement stock availability for male and female cattle has not been fulfilled. It is recommended not to release Kuantan cattle in the next 5 years to maintain population balance. [ABSTRACT FROM AUTHOR]
