BackgroundThe aims of the current study were to evaluate the inflammatory response in cow uterus and to explore the molecular mechanism triggered by high concentrate-induced subacute ruminal acidosis (SARA) in mid-lactating dairy cows. Twelve mid-lactating Holstein cows with an average weight of 455 kg were allocated into two groups subjected to two diets for 18-weeks either a low-concentrate (LC) group containing 4:6 (NDF: NFC) and a high-concentrate (HC) group containing 6:4 (non-forage carbohydrates, NFC): (neutral detergent fiber, NDF) ratio based on dry matter.ResultsThe HC group showed lower ruminal pH and higher lipopolysaccharide (LPS) concentrations in both the rumen and peripheral plasma compared to the LC group. The LPS concentrations in the rumen fluid and the peripheral plasma were found significantly increased in the HC group compared to the LC group. The concentrations of IL-1β, TNF-α and IL-6 were significantly higher in the HC group compared to the LC group. The uterus of SARA cows revealed elevated mRNA concentrations of nuclear transcription factors and pro-inflammatory cytokines, which confirmed the presence of inflammation. The occurrence of uterine inflammation was further validated by the increased protein expression of NF-κB-p65 and its active phosphorylated variant in the uterus of SARA cows. Similarly, the inflammatory genes TLR4, LBP, MyD88, TRAF-6, NF-κB, IL-6, IL-8, TNF-α and IL-1β were significantly upregulated in the uterus of the HC versus the LC group.ConclusionTherefore, the results indicated that LPS derived from the rumen triggered the genes associated with inflammation in the uterus of mid-lactating dairy cows fed a high-concentrate diet, causing endometritis.

“…The kosher meat production practices, the religious slaughter procedures and the pre- and post-slaughter processes and technologies to improve kosher meat quality have been widely discussed in the literature (Farouk et al , 2014; Torres et al , 1988; Zuckerman and Mannheim, 2001; Holzer et al , 2004; Asghar et al , 1990; Powers and Mast, 1980; Mast and Macneil, 1983; Angel et al , 1989; Hajmeer et al , 1999; Anil et al , 2004; Nakyinsige et al , 2014; D’Agata et al , 2009; Leal-Ramos et al , 2011; Sazili et al , 2013). In particular, Miele (2013) questioned about the methods of religiously acceptable killing by Jewish communities; indeed, the author concentrated on the religious animal slaughter issue that raised as safer in contrast with the introduction of the electrical stunning prior to cutting throat as general practice.…”

Purpose Increased awareness about the importance of a safe, healthy nutrition has changed human interactions with food and increased worldwide demand for high quality and ethical food. In this respect, the purpose of this paper is to highlight the concept of ethical food and the nature of kosher food production, assessing common traits and the main differences between the two. A literature review was undertaken in order to verify the direction in which further studies might proceed. Design/methodology/approach A research review on current literature was carried out exploring concepts of ethical food and food certification underpinning kosher businesses by means of an analysis of both producers’ and consumers’ perspectives. In order to proceed with an accurate analysis, the paper matches both the conceptual analysis and the bibliometric one. The overlap between these two forms of analysis makes results robust and useful for future research. Findings This review reveals common points between ethical and kosher food because attention is given to both processes and products and the way the market perceives them as expressions of trustworthy and safe production. Furthermore, the analysis reveals an under emphasis on kosher food in the academic world and the results reveal the importance of empirical analysis. Research limitations/implications The analysis is focused mainly on kosher food production as an expression of ethical food. It would be interesting, however, to expand the analysis to other types of ethical certification such as Halal food, for example, in order to perform comparative evaluations. Practical implications From a practical point of view, it is interesting to note that kosher food is conceived as very safe food and that non-religious people are sensitive to this, which opens new horizons for ethical food. It also offers the possibility that firms that have never considered entering the field of ethical food certification may do so to expand their businesses. This implication also reveals that there is a higher attention on sustainability and safety in agro-food market. Therefore there are great opportunities of expansion for ethical food. Social implications From a social point of view, this paper is of importance for several reasons. It deals with a relatively new and relatively unexplored issue; it points out the relevance of sustainability and safety in food market and consumer behavior, it presents the possibility of exploring knowledge interactions between different perspectives (multidisciplinary approach) and cultures which, in the opinion, will present significant challenge in relation to agro-food business research in the future. Originality/value The originality of this work is that of systematizing a literature review of ethical food, enlarging its scope and boundaries with specific reference to kosher food. It also highlights the need to focus on both management and marketing, since up to now there has been a lack of academic contributions to these areas of research. Directi...

“…All the lambs were weighed, following withholding feed for 24 h and water for 2 h, and then harvested at the Lintao Huajia Animal Husbandry Co., Ltd. after the 180 d feeding experiment using the Islam exsanguination method (D'Agata et al, 2010). After exsanguination, a small cut was made through the hide with a scalpel and air was pumped between the hide and the subcutaneous fat (SF) to separate the wool and hide from the SF.…”

Energy is a key factor regulated by the neuroendocrine system. The objective of this study was to compare growth performance, serum biochemical indices, carcass traits, meat quality, and nutrient composition of lambs fed restricted metabolizable energy (ME) intakes to mimic the seasonal changes of the natural grasslands of northwest China. Nineteen male Dorper × Small Tailed Han lambs were assigned to treatments, control (CON) fed at 1.0 MJ/W 0.75 × d −1 throughout the 180 d study, and restricted ME (RES) fed by sequentially restricting ME every 30 d (0.56, 0.84, 1.0, 0.84, 0.56, and 0.28 MJ/W 0.75 × d −1). Lambs were harvested at the end of the study. Lambs fed the CON diet demonstrated higher (P < 0.05) average daily gain (ADG) compared with RESfed lambs (158.79 and 57.01 g/d, for CON and RES, respectively), although ADG were lower in each period with the last period being a negative ADG for RES-fed lambs resulting in a loss of body weight. Both treatments demonstrated lower ADG in the last 3 study periods compared with the first 2 periods, which may be explained by cold stress (<−3 °C) increasing the lamb's energy requirement. Feeding lambs a restricted ME diet resulted in lower (P < 0.05) blood serum glucose, triglycerides, total protein, calcium, phosphorus, immunoglobulin G, immunoglobulin M, and immunoglobulin A concentrations compared with CON-fed lambs, but both treatments were similar (P > 0.05) for cholesterol and high-density lipoprotein-cholesterol. Feeding lambs a restricted ME diet increased (P < 0.05) meat pH, while reducing the cooked meat rate compared with CON-fed lambs. Thus, the carcass yield, rib eye muscle area, and shear force were lower (P < 0.05) for RES-fed lambs compared with CON-fed lambs. The meat water concentration was higher (P < 0.05), whereas the concentrations of dry matter, crude fat, crude protein, and carbohydrate were lower (P < 0.05) for lambs fed a RES ME diet compared to CONfed lambs. These results demonstrate that sequentially restricting ME intake, as natural grasslands might experience during seasonal forage quality and quantity changes, resulted in a reduction of body weight because lambs were mobilizing body reserves as a source of ME. The reduction in concentrations of key serum nutrients, as well as carcass traits and meat composition, demonstrate the body is responding to the meet the lambs ME requirements, which has implications for both meat quality and the animal's physiological functions.
