The compromised egg quality and leg abnormality during the end of the laying cycle (after 40 weeks) have been leading to poor animal welfare and substantial economic losses. Therefore, the effects of fermented calcium (Ca) butyrate, produced by fermentation by , on production, eggshell quality, and tibial property of hens were explored. A total of 192 Hy-line brown laying hens at 50-week-old were assigned

Nutr. (IF 6.1) Pub Date : 2024-01-03 Huixia Yu, Shuo Geng, Shuai Li, Yingwei Wang, Xin Ren, Debin Zhong, Haolin Mo, Mingxing Yao, Jiajia Yu, Yang Li, Lixin Wang
Fibroblast growth factor 1 (FGF1) regulates vertebrate cell growth, proliferation and differentiation, and energy metabolism. In this study, we cloned rainbow trout () and , prepared their recombinant proteins (rFGF1 and rFGF1a), and described the molecular mechanisms by which they improve glycolipid metabolism in carnivorous fish. A 31-d feeding trial was conducted to investigate whether they could

Trimethylamine oxide supplementation differentially regulates fat deposition in liver, longissimus dorsi muscle and adipose tissue of growing-finishing pigs Anim. Nutr. (IF 6.1) Pub Date : 2024-01-03 Andong Zha, Wanquan Li, Jing Wang, Ping Bai, Ming Qi, Peng Liao, Bie Tan, Yulong Yin
Trimethylamine oxide (TMAO) is a microbiota-derived metabolite, and numerous studies have shown that it could regulate fat metabolism in humans and mice. However, few studies have focused on the effects of TMAO on fat deposition in growing-finishing pigs. This study aimed to investigate the effect of TMAO on fat deposition and intestinal microbiota in growing-finishing pigs. Sixteen growing pigs were

Mannanase improves the growth performance of broilers by alleviating inflammation of the intestinal epithelium and improving intestinal microbiota Anim. Nutr. (IF 6.1) Pub Date : 2024-01-03 Xiaodan Zhang, Huiping Xu, Lu Gong, Jiao Wang, Jianyang Fu, Zengpeng Lv, Liangjuan Zhou, Xuejun Li, Qiong Liu, Pingyu Xia, Yuming Guo
This experiment aimed to discuss and reveal the effect and mechanism of mannanase on intestinal inflammation in broilers triggered by a soybean meal diet. In this experiment, 384 Arbor Acres broilers at 1 d old were randomly divided into 3 treatment groups. The broilers were fed a corn-soybean meal basal diet, a low-energy diet (metabolizable energy reduced by 50 kcal/kg), and a low-energy diet supplemented

How neonatal diet affects the long-term development of rumination behavior, rumen fermentation and feed digestion in dairy calves fed a high milk level? Anim. Nutr. (IF 6.1) Pub Date : 2023-12-30 Jianxin Xiao, Tianyu Chen, Rong Peng, Gibson M. Alugongo, Hui Yang, Shuai Liu, Yulin Ma, Jingjun Wang, Shengli Li, Zhijun Cao
This study was to investigate growth performance, rumination development, rumen fermentation and feed digestion in young calves provided high volumes (about 20% of calf birth weight) of milk with or without forage inclusion and how these parameters correlate with each other. Immediately after birth, 160 newborn Holstein female calves (41.6 ± 4.2 kg of initial BW) were randomly divided into 2 treatments:

Effect of red clover isoflavones on hormone, immune, inflammatory, and plasma biochemistry in lactating dairy cows Anim. Nutr. (IF 6.1) Pub Date : 2023-12-27 Shiqi Zhang, Xiaoyin Zhang, Zhanbo Xiong, Kexin Li, Yuan Gao, Ying Bu, Nan Zheng, Shengguo Zhao, Jiaqi Wang
This study was to conducted to investigate the effect of red clover isoflavones on the health indicated by immune status and blood biochemistry in dairy cows. Sixty-eight healthy Holstein lactating cows were randomly divided into four treatments ( = 17 per treatment) from 5 blocks according to milk yield using a randomized complete block design. No initial differences in parity (2.13 ± 1.21), days

Diarrhea induced by insufficient fat absorption in weaned piglets: Causes and nutrition regulation Anim. Nutr. (IF 6.1) Pub Date : 2023-12-27 Yuying Li, Pengjun Shi, Kang Yao, Qian Lin, Mansheng Wang, Zhenping Hou, Wenjie Tang, Hui Diao
Fat is one of the three macronutrients and a significant energy source for piglets. It plays a positive role in maintaining intestinal health and improving production performance. During the weaning period, physiological, stress and diet-related factors influence the absorption of fat in piglets, leading to damage to the intestinal barrier, diarrhea and even death. Signaling pathways, such as fatty

Determination of the standardized ileal digestible calcium requirement of Ross broilers from hatch to day 14 post-hatch Anim. Nutr. (IF 6.1) Pub Date : 2023-12-20 Carrie L. Walk, Raffaella Aureli, Pauline Jenn
An experiment was conducted to determine the standardized ileal digestible (SID) calcium requirement of fast-growing broilers from hatch to d 14 post-hatch. Ross 308 ( = 360) male broilers were obtained on day of hatch and allocated to 1 of 5 treatments in battery cages. There were 6 birds per cage and 12 pens per treatment. Four treatments were formulated to contain 0.60%, 0.46%, 0.32% or 0.18% SID

Prediction of net energy of feeds for broiler chickens Anim. Nutr. (IF 6.1) Pub Date : 2023-12-20 Aye-Cho Tay-Zar, Manoosak Wongphatcharachai, Pairat Srichana, Pierre-André Geraert, Jean Noblet
Net energy (NE) enables the prediction of more accurate feed energy values by taking into account the heat increment which is approximately 25% of apparent metabolizable energy (AME) in poultry. Nevertheless, application of NE in poultry industry has not been practiced widely. To predict the NE values of broiler diets, 23 diets were prepared by using 13 major ingredients (wheat, corn, paddy rice, broken

Dietary sodium acetate and sodium butyrate attenuate intestinal damage and improve lipid metabolism in juvenile largemouth bass (Micropterus salmoides) fed a high carbohydrate diet by reducing endoplasmic reticulum stress Anim. Nutr. (IF 6.1) Pub Date : 2023-12-20 Liulan Zhao, Liangshun Cheng, Yifang Hu, Xiaohui Li, Yihui Yang, Jin Mu, Lianfeng Shen, Guojun Hu, Kuo He, Haoxiao Yan, Qiao Liu, Song Yang
High-carbohydrate (HC) diets decrease the intestinal levels of sodium acetate (SA) and sodium butyrate (SB) and impair the gut health of largemouth bass; however, SA and SB have been shown to enhance immunity and improve intestinal health in farmed animals. Thus, the present study was to investigate the effects of dietary SA and SB on HC diet-induced intestinal injury and the potential mechanisms in
