β-glucosidase, driven by porcine transthyretin promoter, specific expression in the liver of transgenic mice Anim. Sci. J. (IF 2.0) Pub Date : 2023-12-12 Feng Zhang, Yujiao Li, Qi Xiong, Jin Chai, Siwen Jiang
Under the background of food security, using non-grain feed instead of corn–soybean-based feed is an effective measure to alleviate the food-feed competition. While, non-grain feeds are often rich in fiber, which cannot be digested by non-ruminants. Producing heterologous enzymes in non-ruminants to improve cellulose utilization rate is a new research strategy by transgenic technology. In this study

Evaluation of modified dried vinasse as an alternative dietary protein source for broilers Anim. Sci. J. (IF 2.0) Pub Date : 2023-12-13 İlyas Onbaşılar, Sakine Yalçın, Emre S. Gebeş, Suzan Yalçın, Aydın Şahin
The increase in poultry production and the high cost of soybean led to the search for alternative protein sources. One of these sources is vinasse, a by-product of the baker's yeast industry. Modified dried vinasse (MDV) can be produced for use in poultry nutrition by making some improvements in vinasse. Therefore, the present study aimed to examine the effect of the usage of MDV in broiler diets.

Ultrasonographic patterns of different regions of uterus according to pregnancy in cows and heifers Anim. Sci. J. (IF 2.0) Pub Date : 2023-12-07 Kemal Tuna Olğaç, Murat Onur Yazlik, Ufuk Kaya, Mehmet Borga Tirpan
This study aimed to detect pregnancy within the first 20 days after artificial insemination by evaluating the ultrasonographic patterns of the different regions of uterus in Holstein heifers and cows. Animals were divided into subgroups according to pregnancy on 28th day as pregnant (heifer, n: 15; cow, n: 15) and non-pregnant (heifer, n: 15; cow, n: 15). Images were taken from the ovulation-side cornu

Effect of seaweed feeding before calving on colostral IgA concentration in Japanese Black cows Anim. Sci. J. (IF 2.0) Pub Date : 2023-12-07 Maho Yamanaka, Ayuka Sanada, Toshinori Nakagawa, Katsuyoshi Sato, Jun Watanabe, Masaki Yokoo, Takuji Hirayama
In this study, we investigated the effect of feeding seaweed to Japanese Black cows before calving on IgA concentrations in colostrum. Seven Japanese Black breeding cows were used as test animals, with three cows in the seaweed-fed group (seaweed group) and four in the seaweed-non-fed group (control group). Each cow was fed 6 kg of sudangrass hay and 2.5 kg of compound feed twice daily (09:00 a.m.

Effects of intravaginal administration of prostaglandin F2α on luteolysis and subsequent estrus in Shiba goats (Capra hircus) Anim. Sci. J. (IF 2.0) Pub Date : 2023-12-07 Yumi Akamatsu, Tomomi Tanaka, Natsumi Endo
This study examined the effects of intravaginal administration of prostaglandin F2α (PGF2α) on luteolysis and subsequent estrus in cycling goats. Goats with functional corpus lutea received one of five treatments: 2 mg of PG intramuscularly (IM2 × 1; n = 6), 2 mg of PGF2α intravaginally (IVG2 × 1; n = 7), 4 mg of PGF2α intravaginally (IVG4 × 1; n = 7), and 1 or 2 mg of PGF2α intravaginally 8 h apart

Qualitative and quantitative analyses in sulfated glycosaminoglycans, chondroitin sulfate/dermatan sulfate, during 3 T3-L1 adipocytes differentiation Anim. Sci. J. (IF 2.0) Pub Date : 2023-12-06 Danang Dwi Cahyadi, Katsuhiko Warita, Naoko Takeda-Okuda, Jun-ichi Tamura, Yoshinao Z. Hosaka
Chondroitin sulfate/dermatan sulfate (CS/DS) is a member of glycosaminoglycans (GAGs) found in animal tissues. Major CS/DS subclasses, O, A, C, D, and E units, exist based on the sulfation pattern in d-glucuronic acid (GlcA) and N-acetyl-d-galactosamine repeating units. DS is formed when GlcA is epimerized into l-iduronic acid. Our study aimed to analyze the CS/DS profile in 3 T3-L1 cells before and

Effects of alpha lipoic acid treatment during in vitro maturation on the development of porcine somatic cell nuclear transfer embryos Anim. Sci. J. (IF 2.0) Pub Date : 2023-11-29 Takehiro Himaki, Kazuki Hano
Oxidative stress influences the embryo production efficiency in vitro. We investigated the effects of alpha lipoic acid (ALA) treatment during the in vitro maturation (IVM) period on the porcine somatic cell nuclear transfer (SCNT) embryo production. After IVM, maturation rates of the 12.5- and 25-μM ALA-treated groups were not significantly different from those of the 0-μM ALA-treated group. Compared

Relation between postpartum calf-licking behavior and agonistic behavior against handlers by primiparous beef cows Anim. Sci. J. (IF 2.0) Pub Date : 2023-11-29 Shiho Yamada, Shigeru Ninomiya
Maternal protective behavior in cattle husbandry settings is typically manifested as agonistic behavior against farm staff handling the calves. Investigating factors related to agonistic behavior of cows is important. Agonistic behaviors of 30 primiparous cows against farm staff handling their calves during the immediate postpartum period were observed using continuous recording. Relations between

Dietary puerarin supplementation improves immune function in the small intestines of oxidized oil-challenged broilers Anim. Sci. J. (IF 2.0) Pub Date : 2023-11-29 Hua Zhou, Yingmei Yu, Xuan Shi, Tiande Zou, Lei Yang, Jingxin OuYang, Yinhao Bian, Yichun Liu, Guanhong Li
Puerarin has possessed a wide range of pharmacological activities. However, little is known about the protective effects of puerarin on the oxidized oil-induced injury. Here, we describe the anti-inflammatory effects of puerarin in chickens. A total of 360 broilers were arranged in four treatments. Diets included two types of soybean oil (fresh or oxidized) and two levels of puerarin (0 or 750 mg/kg)

The effects of replacing wheat and soyabean meal with duckweed (Lemna minor) and including enzymes in the diet of laying hens on the yield and quality of eggs, biochemical parameters, and their antioxidant status Anim. Sci. J. (IF 2.0) Pub Date : 2023-11-29 Payam Baghban-Kanani, Marianna Oteri, Babak Hosseintabar-Ghasemabad, Saba Azimi-Youvalari, Ambra Rita Di Rosa, Biagina Chiofalo, Alireza Seidavi, Clive J. C. Phillips
Duckweed is a rapidly growing aquatic plant, which could be used in the diet of laying hens to enhance carbon capture and improve land use efficiency. Digestion may be improved by supplementation with exogenous enzymes. We replaced soyabean meal and wheat with duckweed in a 10-week study with 432, 60-week-old Hy-Line W-36 layers, divided into six isocaloric and isonitrogenous dietary treatments, each
