“…This, consequently, increases the production of haemoglobin and thereby increases the MCHC values. In the present study, the change in MCHC value was not accompanied by the changes in the numbers of erythrocytes and haemoglobin, which was similarly seen in the study of Ulupi et al (2018). The higher MCHC value in BTRT+FRMT chicks may also be related to the higher metabolic activity resulting in higher BW in these respective chicks at day 21.…”

“…Considering that MCHC reflects the haemoglobin content of erythrocytes, the increased MCHC value may imply in the elevated haemoglobin production to increase the oxygen transport capacity of erythrocytes. This latter inference was supported by Ulupi et al (2018) revealing that during the hypoxic state broiler chicks tend to produce large quantities of Table 5.

The study investigated the influence of dietary incorporation of formic acid, butyric acid or their blends on growth rate, haematological indices and intestinal morphometric of broilers. A number of 240 Lohmann MB-202 chicks were pass rounded to four dietary groups, including CONT (chicks taking in basal feed with no additive), BTRT (chicks receiving basal feed with 0.03% butyric acid), FRMT (chicks receiving basal feed with 0.1% formic acid) and BTRT+FRMT (chicks receiving basal feed containing 0.03% butyric acid and 0.1% formic acid). Weight of chicks and intake were measured every week, while blood sample was collected at day 21 and 35. At day 35, birds were slaughtered and small intestinal segments and digesta were collected. At day 21, body weight was bigger (P<0.05) in BTRT+FRMT than in other birds. Feeding the blends of formic and butyric acids resulted in higher (P<0.05) value of mean corpuscular haemoglobin concentration (MCHC) at day 21. Feeding organic acids was associated with the lower (P<0.05) proportion of thrombocytes in broilers at day 35. Supplementation of butyric acid resulted in higher (P<0.05) serum albumin concentration at day 35. Butyric acid produced higher (P<0.05) levels of triglyceride as well as low-density lipoprotein (LDL) in the serum. The mixture of formic and butyric acids resulted in higher (P<0.05) titer of antibody against Newcastle disease vaccine (NDV) at day 21. Feeding formic acid decreased (P<0.05) ileal population of lactose negative enterobacteria at day 35. Overall, dietary supplementation of the blends of formic and butyric acids resulted in improved growth and immune defence of broiler chicks.

“…Indeed, the microclimate of shipments can be influenced by climatic conditions during transport [104]. Therefore, transport distance and duration, as well as climatic conditions, can interfere with broiler welfare and behaviour [105] and, ultimately, with their performance [106,107].…”

Animal Welfare, Health and the Fight against Climate Change: One Solution for Global Objectives

Climate change is internationally recognized as a source of concern by governments, scientists and public opinion. In this context, the need to find concrete solutions becomes increasingly urgent. Numerous economic sectors contribute to alteration of climate, especially livestock and, more generally, food production-related activities. For this reason, animal welfare policies, the complex of norms and regulations adopted by single Member States and the European Union in the field of meat production, could be a useful instrument in the climate transition invoked by policy makers and scientists. The aim of this paper was to analyze the current system of animal welfare from a legal and veterinary perspective, and to demonstrate how important and useful, it could be in the fight against climate change; at least if correctly implemented and applied.

“…Carcass bruises can occur during broiler catching or during transport, when the birds are exposed to social changes (such as mixing chickens with different groups from those established during the rearing period) [24,25] and to microclimatic factors that culminate in the crowding of birds in the transport crates [26]. Therefore, transport distance and duration as well as climatic conditions during transport can interfere with broiler welfare and behavior [27] and, ultimately, with their performance [15,28].…”

Effect of transportation distances, seasons and crate microclimate on broiler chicken production losses

The goal of this research was to evaluate the microclimate (temperature, relative humidity and ECI-enthalpy comfort index) of commercial loads of broiler chickens at different transport distances: Dist15 (15 km on average) and Dist90 (90 km on average) in the summer and winter seasons and their effects on the production parameters body weight difference (BWD), mortality (%) and bruising prevalence (%). Twelve broiler loads were monitored using dataloggers to record temperature and humidity, with a total of 24 target crates per load. The experiment followed a factorial design [2 seasons (rainy and dry) × 2 distances (Dist15 and Dist90)] with a randomized complete block arrangement, 3 sexes (all males, all females, or mixed shipments) and one shipment per combination. BWD had a heterogeneous distribution throughout the load, and this distribution was not significantly correlated with the mean ECI measured during transport at 12 positions along the load. In terms of comfort, summer is the most critical period for broiler transport. In the interaction between rainy season and Dist90, the highest ECI was scored in the lethal zone (where physiological mechanisms are not enough to control body temperature). Mortality during the rainy season was not significantly different between distances. However, during the dry season, mortality was twice as high as broilers that travelled for 15 km. The prevalence of bruising on carcasses was not affected by the interaction between season and distance. As we know, broiler chicken performance, during transport, can be also related to road conditions, being hard to evaluate the real impact of seasons and distances on animal welfare. Load microclimate can compromise broiler chicken welfare during transport and it does not necessary reflect significant losses pre and post-slaughter.
