The present study explored the effects of substituting maize gluten meal with increasing levels of partially defatted black soldier fly larvae meal (BSFLM) in Muscovy ducks’ diets on their caecal microbiota and organic volatile compounds. The ducks were divided into four groups, each receiving a diet containing 0%, 3%, 6%, or 9% BSFLM (HI0, HI3, HI6, and HI9, respectively). At slaughter (50 days of age), caecal samples were collected and analysed. The alpha diversity indexes were lower in the HI9 than in the HI0 and HI3 treatments that did not differ between them. Bacteroidetes in the HI0 and Firmicutes in the HI6 treatment showed a higher abundance than in the HI9 treatment. Faecalibacterium and Megamonas were more abundant in the HI6 than in the HI9 treatment. Abundance of Clostridium and unclassified Coriobacteriaceae were higher and lower, respectively, in the HI9 than in the HI0 treatment. Canonical discriminant analysis revealed that Faecalibacterium, unclassified Victivallaceae and Megamonas in relation to Ruminococcus would separate the HI6 and HI9 treatments, while unclassified Coriobacteriaceae in relation to Streptococcus and Faecalibacterium would distinguish the HI0 and HI3 from the HI6 and HI9 treatments. Eleven volatile compounds were more abundant HI9 than in the HI6 treatment. Five of them were negatively correlated with Faecalibacterium and two with Megamonas. These findings indicate that diets with 6% and 9% BSFLM alter the caecal microbiota in Muscovy ducks, while a diet with 3% BSFLM has no effect. The distinct abundance of several volatile compounds in the 6% and 9% BSFLM treatments suggests a relationship between their characteristic microbiota profile and those compounds that warrants further investigation.

The aim of this study was to evaluate the effect of species on added lead (Pb) and cadmium (Cd) content in cow, buffalo, and goat milk and their distribution in fat, casein, and whey fractions. In addition, the oxidative stability of the milk was evaluated. Most of the Pb and Cd were recovered in the skimmed milk (96.74 and 94.21%, respectively). The distribution of Cd and Pb in casein and whey fractions, obtained by enzymatic coagulation, highlighted that they were mainly associated with casein (on average 94.77 and 90.54% of Pb and Cd, respectively). The species significantly affected the distribution of Cd and Pb in the casein and fat fractions (p < 0.01). In particular, Cd and Pb levels in fat fraction were the highest in the buffalo milk, whereas casein fraction was the highest in bovine milk. Furthermore, the presence of metals negatively influenced the oxidative stability of the milk and the species influenced its response. The results showed that in the presence of Cd and Pb, bovine milk increased the content of Malondialdehyde (MDA), advanced oxidation protein products (AOPP) and dithyrosines compared to other species. In addition, there was a significant decrease in the thiol content, highlighting a reduction in the antioxidant capacity of the contaminated milk.

Alpacas represent an exotic species for Italy, introduced no more than 20–30 years ago. Nevertheless, they are currently the most widespread camelid species reared in this country, highlighting the growing interest in breeding this species. So, it is useful to assess parameters on their growth in relation to the new environment. Thus, body weight and body measures were recorded on 49 healthy alpacas of Huacaya type (27 females, 22 males), along a period of 27 months. Overall, 111 individual observations were made. Data were analysed by ANOVA, as growth curves were estimated by applying the Gompertz’s model. Multiple regression was finally used to estimate body weight from body measures. Body weight and linear measures, except for the distance between iliac crest and the length of the rump, were influenced by the category (calves, yearlings, adults) and by the age class within category (p < 0.05), while gender and interaction between gender and category were never significant (p > 0.05). Asymptotic weigh of males was 8.25% higher than females (p < 0.05). Moreover, males at maturity had higher withers (+0.96%), longer body (+2.70%) and chest measurements (+3.18%) than females. Asymptotic rump width (both at the ilium and at the ischium) was higher in females (respectively + 6.19%; +12.90%). According to our work, the best equation for the estimate of body weight from body measures was the following: 5.691 + 0.00005624 * chest circumference3 + 0.00002298 * trunk length3 − 1.155 * rump width between ischial tuberosities + 0.00001545 * height at rump3 (R2=0.957; SE of estimate = 4.36 kg), that is important for a better management of the species.

The study aimed to verify the influence of different milking machine setting parameters on Italian Mediterranean buffalo milking performance. Data on milking machine settings (Milking Dry Tests [MDTs]) and milk Test-day (TD) were collected by the Italian Breeders Association (AIA). Data for each TD consisted of milk yield (MY), fat percentage (FP), protein percentage (PP), lactose percentage (LP) and linear score (LS). Working vacuum level (VL), pulsation ratio (PR), automatic cluster removal system (AC) and effective vacuum reserve (EVR) were recorded from each MDT. A total of 558 MDTs, 217,967 TD, collected from 43,593 buffaloes in 198 buffalo farms were utilised. MDT, TD and Animal data (AD) were analysed through a mixed linear model and a logistic regression model was used to evaluate the relationship between VL and EVR. Analysis of MY and quality revealed that an incorrect setting of the milking was responsible for a higher LS and lower MY and LP, along with higher FP and PP compared to farms with adequate EVR. Except for PP, the height of the milking system significantly influenced all milk parameters. Conversely, VL affected all milking traits. A higher PR (70:30) was responsible for significantly lower LS and higher FP compared to a 60:40 PR. Similarly, the presence of AC showed a significant effect on FP and MY and a slight reduction in LS. Finally, the diameter and length of the pipeline (DL) ratio lower than 2.5 m was associated with a decrease in LS. These results suggest that buffaloes require specific milking parameters.

Animal welfare protection is a challenge for which policy-makers are demanding scientific-based evidence. Considering horses, the challenge is even greater, as their role in society varies from production to companion animals. This review aimed to describe the evolution and geographical distribution of horse welfare literature over the years, to identify the most studied research topics and to highlight the still present gaps in knowledge. A search on Scopus® bibliometric database was performed using different welfare-related keywords. Predetermined filters were posed on time range, language and subject area. A total of 6584 records were downloaded and screened retaining only the ones dealing with horse welfare and behavioural sciences. Descriptive statistics, text mining (TM) and topic analysis (TA) were performed on the abstract of 801 eligible records. The results showed the number of studies on horse welfare is exponentially increasing, especially in the European continent. ‘Transport’ was the most frequent word, but also ‘behaviour’ and ‘pain’ emerged. Nine topics were identified and covered different subject areas: stress analysis, pain assessment, equitation science, human–horse interactions, breeding management, transport, working equids and health. The evaluation of stress and pain, horse social behaviour and the human–horse relationship resulted to be the most studied aspects related to animal welfare. On the contrary, the concept of positive welfare and the welfare assessment at slaughter of horses were underrepresented, confirming the limited literature on these subjects. This review confirmed the growing impact of research on horse welfare and highlighted how some important areas still do not provide sufficient scientific evidence.

The purpose of this experiment was to use a single-factor design to investigate the effects of different supplementation levels of plant essential oil/palygorskite composite (EPO-Pal) on growth performance, blood parameters, and intestinal morphology of broiler chicken. A total of 960 one-day-old chicks were randomly assigned into 4 treatments with 6 replicates of 40 chicks each. The broilers were fed the basal diet supplemented with 0, 500, 750, and 1000 mg/kg EPO-Pal for 42 days, respectively. The results showed that the 500 or 750 mg/kg groups significantly increased the body weight, average daily feed intake and average daily gain of the broilers at 28 and 42 days (p < 0.05). Additionally, as compared to the control group, the 1000 mg/kg EPO-Pal group exhibited higher levels of immunoglobulins-A, immunoglobulins-G, immunoglobulins-M, and high-density lipoprotein cholesterol while having lower levels of tumour necrosis factor-α (p < 0.05). The content of interleukin-2 and the villus height-to-crypt depth ratio were significantly increased in the 750 mg/kg EPO-Pal group (p < 0.05). Moreover, the activity of total antioxidant capacity and superoxide dismutase were significantly enhanced in the 500 mg/kg EPO-Pal group (p < 0.05). The results are very promising, and EPO-Pal can be considered as an additive to promote the growth by enhancing immunity, antioxidant activity, and improving the intestinal morphology of broiler chickens.
