This study was conducted to detect the prevalence of Babesiosis in different areas at Baghdad city, by using microscopic examination ;180 sheep’s head blood samples were collected from each local breed (122 males and 58 females) with different age groups from 6 months to more than one year old, during the period extended from 1/October2019 to end of April 2020.Giemsa stained blood smears were done for detection Babesia spp. ; The overall rate of  infection with Babesia spp. in sheep was 15.55% (28/180), significant differences P≤0.05 was  recorded between male 19.67% ( 24/122) and female 6.89% ( 4/58 ), and sheep with  equal or more than one year old  registered higher rate of  infection 18.18% (2/11) , also highest rate of infection recorded in April 45% (9/20) with highly significant differences P≤0.01 between months of study.

Modern pig breeds, which have been genetically improved to achieve fast growth and a lean meat deposition, differ from local pig breeds with respect to fat deposition, fat specific metabolic characteristics and various other properties. The present review aimed to elucidate the mechanisms underlying the differences between fatty local and modern lean pig breeds in adipose tissue deposition and lipid metabolism, taking into consideration morphological, cellular, biochemical, transcriptomic and proteomic perspectives. Compared to modern breeds, local pig breeds accumulate larger amounts of fat, which generally contains more monounsaturated and saturated fatty acids; they exhibit a higher adipocyte size and higher activity of lipogenic enzymes. Studies using transcriptomic and proteomic approaches highlighted several processes like immune response, fatty-acid turn-over, oxidoreductase activity, mitochondrial function, etc. which differ between local and modern pig breeds.

White-backed and Ash-grey cows yielded an average of 6212 kg and 6078 kg of milk per year, with 4.25–4.28% fat and 3.37–3.40% protein, while Holsteins averaged 10,694 kg with 4.47% fat and 3.45% protein. The study aimed to analyse the fatty acid (FA) profile of milk from two local cow breeds, compare them with that of Holstein cows, and evaluate the influence of lactation number, productivity indicators and milk colour. The study was carried out with White-backed (n = 40), Ash-grey (n = 49), and Holstein (n = 51) cows. Based on lactation number, cows were divided into two groups. Composite milk samples from all quarters of each cow were collected. Two additional milk samples were taken: 1st to assess milk colour and the second to determine the fatty acids profile. Productivity data of cows were provided from the Livestock Information System. Statistical analysis included calculating means and standard deviations or standard errors of the mean. One-way and two-way ANOVA (breed and lactation) were used, and Duncan’s test was applied to compare mean values between groups. White-backed cows contained greater proportions of C17:0, C17:1, C18:3 ω3, and C20:0 (p < 0.05), as well as higher total omega-3 and polyunsaturated fatty acid (PUFA) contents. Parity did not have a significant effect on productivity indicators, but parity influenced the FA profile. Milk from 1st-lactation Ash-grey cows showed higher levels of PUFA and omega-6 fatty acids (p < 0.05). Milk from Ash-grey cows has more favourable visual attributes, indicating improved suitability for dairy processing, where colour uniformity is important for technological quality.

The objectives of this study were (i) to analyze the ClassyFarm welfare scores in loose housing system (LHS) and tied housing system (THS) Rendena herds, and (ii) to investigate the influence of the housing on individual milk yield and quality traits in Rendena cows. The dataset consisted of 3761 individual milk samples from 750 Rendena cows, collected between August 2022 and November 2023 from 17 single-breed herds of the Veneto region. Available data included days in milk (DIM), parity, and milk yield, as well as fat, protein, casein, and lactose contents, somatic cell count, differential somatic cell count, and urea concentration. For milk traits, a linear mixed model included housing system, DIM, and parity as fixed effects, while cow, herd-test-date, and residual variability were random effects. In both housing systems, a good level of welfare was observed, although shortcomings in biosecurity measures were identified in both LHS and THS. Milk quality (in terms of protein % and casein %) and yield were higher in LHS compared to THS. The observed differences cannot be explained by the housing system alone, as other management and nutritional factors may have played a role, highlighting the need for further studies to clarify these contributions.

Bianca di Saluzzo (BS) and Bionda Piemontese (BP) are two Italian chicken breeds, mainly reared for meat production, primarily in antibiotic-free farming. However, technical information on their growth pattern is still missing. At hatching, 150 unsexed chicks of each breed were weighed, labeled, and reared in indoor pens up to 8 w of age. At 8 w of age, the chicks were separated by sex and randomly transferred to growing pens with access to an external paddock (15 birds/pen; 4 pens/sex for each breed). The body weight (BW) was recorded biweekly for each bird, from hatching to 32 w of age. In order to identify an improvement strategy, the objectives of our study were to analyze the growth pattern of these birds using the Gompertz mathematical model and compare results with other chicken breeds. Polymorphism of the PAX7 gene was also analyzed to test its association with growth traits. Both BS and BP are close to unselected native breeds and, among the Italian local poultry, they are confirmed to be slow-growing birds with an intermediate size between heavy and light chicken breeds. Regarding the PAX7 gene, two alleles were found, F and G, and showed an association with the actual BW in the BP females from 14 w of age onwards. The G allele always exhibited a more favorable effect than the F allele. In small size poultry population, a delicate balance between preservation of biodiversity and performance improvement should be considered. Consequently, the most proper way could be an approach based on a mating scheme to keep inbreeding under control, increase growth rate, and improve commercial maturity.

The Slovenian autochthonous breed, Krškopolje pig, is known for high fatness and better adaptability to different environmental conditions and feed resources. However, the metabolic processes underlying these adaptations, especially in response to different diets, have not yet been studied. A deeper understanding of these mechanisms could provide valuable insights into the breed’s adaptability to different environmental conditions. Therefore, the main objective of this study was to evaluate the effect of a low-protein (LP) diet on adipose tissue in Krškopolje pigs reared in either organic outdoor (n = 2 × 12) or conventional indoor (n = 2 × 14) systems. In the outdoor system, the LP diet had no effect on adipocyte size compared to the control (high-protein) diet, while it increased lipogenic enzyme activities and monounsaturated fatty acid content, and decreased polyunsaturated fatty acid content (p < 0.05). RNA sequencing revealed the upregulation of 28 genes and the downregulation of 37 genes. The upregulated genes were mainly involved in lipid metabolism (ACLY, FASN, ACACA, MOGAT2), oxidative stress, and mitochondrial function. In the indoor system, pigs on the LP diet had smaller adipocytes (p < 0.05), whereas no differences were detected in the lipogenic enzyme activities or fatty acid composition (p > 0.10). RNA sequencing revealed 30 upregulated and 28 downregulated genes. In the indoor system, heat shock proteins (HSP70.2, HSPA6) were upregulated in pigs on the LP diet, while genes involved in the innate immune system (MSR1, TREM2, CSF3R) were downregulated. To conclude, the present study showed that LP diet affected adipose tissue metabolism and gene expression in Krškopolje pigs, with different transcriptomic responses observed in outdoor and indoor rearing conditions.

HIGHLIGHTS Intrinsic and extrinsic factors strongly affect consumer perceptions about the quality traits of products from native chicken breed. The creation of niche markets that promote native chicken breeds could help safeguard poultry biodiversity. Italian consumers exhibited a fair degree of interest towards meat and eggs obtained from native chicken breeds.

In the northwest of the Iberian Peninsula, characterized by its humid climate, large rural areas are being abandoned, mostly in less-favoured areas covered by heathlands, which present a low nutritive quality for livestock production. The high combustibility of these shrublands is driving a high wildfire incidence with negative environmental and economic effects. In this review, some aspects on wildfire occurrence and the potential of grazing livestock to reduce woody phytomass and fire risk in heathland-dominated areas whilst maintaining quality production and preserving biodiversity are summarized. Heathlands may be partially improved—converted to grassland—to better meet animals’ nutritional requirements while acting as ‘natural’ firebreaks. The specific grazing behaviour offers the opportunity to combine different domestic herbivores (mixed grazing) to achieve sustainable systems utilizing heterogeneous resources. Cattle, sheep, goats, and horses may have a role in the provision of different ecosystem services such as food production and biodiversity conservation. Genotype x environment interactions shape the ability of animals to cope with poor vegetation conditions, with smaller species and breeds performing better than larger animals. Goats and horses are indicated to arrest woody encroachment. Sustainable grazing systems are affordable in heathland–grassland mosaics by selecting appropriate livestock species and breeds for quality production, thus favouring rural economies and lowering fire risk.

The objective of this paper is to summarize the Italian Animal Genetic Resources (ItAnGR) recorded in the Domestic Animal Diversity Information System (DAD-IS) of FAO. The breed data sheets of ItAnGR were implemented by the Italian National Focal Point (ItNFP) of FAO under the guidance of Prof. Donato Matassino and CONSDABI. The impressive amount of work done is documented by 299 breed data sheets. The average level of completeness of the data sheets is 48%, i.e. a value similar to the average for European Countries, and for half of ItAnGR updating is quite regular. The number of breeds/populations included is very high for cattle (61), sheep (84), goats (54), asses (15), horses (34) and pigs (45), while it is very low for chicken (6) and absent for the other species. The level of risk of ItAnGR described in DAD-IS is worrying as about one fifth of the breeds are yet extinct, one fifth is judged critical, almost one fifth is endangered and about two fifth are not at risk, transboundary breeds included. The priority for next years is to complete and update the existing data sheets, to implement new breed data sheets for avian species, buffaloes and shepherd and hunting dogs, and to implement the new PED (Production Environment Description) module for all breeds/populations. It is evident that complete and updated database of ItAnGR is a prerequisite for the implementing of a sound National Plan of Action for the safeguarding of farm animal biodiversity.
