Effects of Feeding Dried Concentrated Rice-Washing Water on Growth Performance and Skeletal Muscle Lipid Peroxidation in Broiler Chickens by Daichi Ijiri, Shogo Nakamura, Kenji Tatsugawa, Satoru Ijiri, Akira Ohtsuka

“…Malondialdehyde (MDA) content, a marker of lipid peroxidation, was significantly lower in the skeletal muscle of chicks fed the HT-CRWW-containing diet compared with chicks fed the control diet; however, MDA content in chicks fed the LT-CRWW-containing diet did not differ from that of controls. …”

The Effect of Koji-feed (Fermented Distillery By-Product) on the Growth Performance and Nutrient Metabolizability in Broiler by Masahiro Yamamoto, Fuad Saleh, Muhammad Tahir, Akira Ohtsuka, Kunioki Hayashi

“…In experiment 1, effects of the diets containing 0.05 and 1.0% Koji-feed on performance and abdominal fat content in broiler chicks were tested. In experiment 2, metabolizable energy of Koji-feed was measured in addition to reexamining the effect of the diet containing 1.0% Koji-feed to confirm the growth promoting effect of Koji-feed. …”

Synergistic Effect of Feeding Aspergillus Awamori and Saccharomyces Cerevisiae on Growth Performance in Broiler Chickens; Promotion of Protein Metabolism and Modification of Fatty... by Ahmed A. Saleh, Kunioki Hayashi, Akira Ohtsuka

“…This study was conducted to examine the effects of a combined in-feed supplementation of Aspergillus awamori and Saccharomyces cerevisiae on growth and muscle protein metabolism and fatty acid profiles in broilers. Chicks (15 d old) were fed a basal diet as control, diets supplemented with 0.05% A. awamori, 0.10% S. cerevisiae, or a combination of both (7 birds/group) for 12 days. …”

Effects of pre-slaughter fasting on antemortem skeletal muscle protein degradation levels and postmortem muscle free amino acid concentrations in broiler chickens by Sachi Katsumata, Mizuki Kamegawa, Ayumi Katafuchi, Akira Ohtsuka, Daichi Ijiri

“…ABSTRACT: This study investigated the effects of pre-slaughter fasting time on the relationship between skeletal muscle protein degradation levels at slaughter and chicken meat quality after 48 h of postmortem aging. Twenty-four broiler chicks at 0 d of age were used in this study until 28 d of age. …”

Effects of Dietary Nano-Selenium Supplementation on Growth Performance, Antioxidative Status, and Immunity in Broiler Chickens under Thermoneutral and High Ambient Temperature Cond... by Mahmoud H. El-Deep, Daichi Ijiri, Tarek A. Ebeid, Akira Ohtsuka

“…The objective of the present study was to examine the effects of nano-selenium on growth performance, antioxidative status, and immune function in broiler chickens reared under thermoneutral (22±1°C) or high ambient temperature (35±1°C) conditions. Thirty-six broiler chicks at 15d old were randomly divided into 6 treatments in a 3×2 factorial design. …”

Dibutoxybutane Suppresses Protein Degradation and Promotes Growth in Cultured Chicken Muscle Cells by Tomomi Kamizono, Akira Ohtsuka, Fumio Hashimoto, Kunioki Hayashi

“…DBB was mixed with the culture medium at the level of 0, 0.015, 0.15, 1.5, 15 and 150 μg/ml and cells derived from thigh muscle of 13-day-old chick embryos were raised for 6 days. The muscle cell growth was accelerated and the rate of protein degradation estimated from Nτ-methylhistidine release into the medium was decreased by DBB. …”
