Sheep habit during hand milking, and relations between the incorrect hand milking procedure and mammary health
2023
This study aimed: (1) to evaluate the relation between the incorrect hand milking and mammary health; (2) to test the hypothesis of the ewe habit in the workstation, of their choice, during the milking. Teat moisturization with foam milk collected from the milk tank represents a high-risk factor because potentially contain mastitis-causing bacteria previously released from affected ewes. Moreover, it was found that sheep are routinary animals by habit during hand milking.
Selected lactic acid bacteria as a hurdle to the microbial spoilage of cheese: Application on a traditional raw ewes' milk cheese
2013
To evaluate the efficacy of lactic acid bacteria (LAB) to improve the hygienic safety of a traditional raw milk cheese, the raw ewes’ milk protected denomination of origin (PDO) Pecorino Siciliano cheese was used as a model system. Different Pecorino Siciliano curds and cheeses were used as sources of autochthonous LAB subsequently used as starter and non-starter LAB. These were screened for their acidification capacity and autolysis. Starter LAB showing the best performance were genotypically differentiated and identified: two strains of Lactococcus lactis subsp. lactis were selected. From the nonstarter LAB, Enterococcus faecalis, Lactococcus garvieae and Streptococcus macedonicus strains…
Chemometric Approaches to Analyse the Composition of a Ewe’s Colostrum
2023
Colostrum is a major source of immunity in lambs and, in general, in all newborn ruminants. It allows the transfer of antibodies from the ewe to the lamb, and it becomes the exclusive source of nutrients for a newborn. Among the most significant Pearson correlations, the positive correlation between the Brix refractive index (Brix) and protein (0.90) should be noted. Both parameters (protein percentage and Brix) were then positively correlated with the percentage of fat (0.38 and 0.41), urea (0.81 and 0.67), calcium (0.39 and 0.29), and magnesium (0.58 and 0.59), as well as the yellowness (0.78 and 0.75). Somatic cell count (SCC) and pH, parameters which are indicators of subclinical mastit…
Effects of diet on casein and fatty acid profiles of milk from goats differing in genotype for αS1-casein synthesis
2013
This study investigated the interactions between nutrition and the genotype at αS1-CN loci (CSN1S1) in goats, evaluating the impact of fresh forage-based diets and an energy supplement on the casein and fatty acid (FA) profiles of milk from Girgentana goats. Twelve goats were selected for having the same genotype at the αS2-CN, β- CN, and κ-CN loci and differing in the CSN1S1 genotype: homozygous for strong alleles (AA) or heterozygous for strong and weak alleles (AF). Goats of each genotype were divided into three groups and, according to a 3 × 3 Latin square design, fed ad libitum three diets: sulla fresh forage (SFF), SFF plus 800 g/day of barley (SFB), and mixed hay plus 800 g/day of ba…
Growth performance in heavy lambs experimentally treated with 17 β-estradiol
2012
European and Italian legislation have banned use of growth promoters in livestock since 1988, but epidemiological data show that anabolic drugs are still being used illegally. Recent surveys carried out on the cattle farms in Northern Italy have confirmed the presence of growthpromoting hormones. Authors report data on growth performances in 80 Valle del Belice×Comisana weaned lambs experimentally treated with 17 beta-estradiol with 0.5 ml solution of oil Depot Estradiol ® (containing 5 mg of 17β- estradiol valerate) by intramuscular injection into the thigh. The experiment was founded by the National Ministry of Health, to validate histological test for surveillance and control of growth-p…

Ruolo chiave della dieta proteico/aminoacidica nel mantenimento del peso in soggetti iperinsulinemici sottoposti a NEP
2012
Ruolo chiave della dieta proteico/aminoacidica nel mantenimento del peso in soggetti iperinsulinemici sottoposti a NEP Matteo Tutino, Giuseppe Morici, L. Cavarra, Francesco Nanfitò, D. Camacaro, Vittorio Calabrese. Università di Palermo, Dipartimento di Biomedicina Sperimentale e Neuroscienze Cliniche - Università di Catania, Dipartimento Biochimica Clinica La Nutrizione Enterale Proteica (NEP) associata alla dieta proteico/aminoacidica è una terapia nutrizionale a scopo dimagrante basata su un’alimentazione essenzialmente proteica. Mentre la NEP consente una rapida perdita di peso, la dieta proteica permette di mantenere nel tempo il risultato ottenuto. La possibilità di alimentarsi manten…
An overview of the microbiological characteristics of the wooden shelves used in cheese ripening
2022
Cheese ripening is a complex phenomenon affected by several factors. Among these, the influence of the wooden shelves used for aging traditional cheeses is underrated. The surfaces of the wooden boards are in contact with cheese rind for the entire ripening period and develop a microbial community. The aims of this review article is to provide an overview on the microbiological approaches applied to study the biofilms associated to the wooden tools used for dairy productions and to summarize the studies specifically performed on the wooden shelves used to ripen traditional cheeses. A critical discussion is focused on the hygienic aspects and the safety of these systems applied in cheese pro…
