L'Istat, Confindustria e l'indice dei salari industriali in periodo fascista
No full textIl saggio propone uno studio della costruzione di indici dei salari industriali in periodo fascista, indagandone le motivazioni politiche e amministrative. nuove fonti potrà chiarire. A una breve premessa dedicata all’evoluzione delle statistiche sui salari industriali nell’Italia unita, fa seguito una discussione più approfondita delle caratteristiche dei dati prodotti in materia nel periodo tra le due guerre da Confindustria e dall’Istat, nonché un esame del dibattito relativo all’attendibilità dell’indice dei salari da questi ricavato e sulla possibilità di ulteriori elaborazioni volte a correggerne le deformazioni più evidenti sulla base delle informazioni disponibili

Short communication: Monitoring nutritional quality of Amiata donkey milk: Effects of lactation and productive season
No full textDonkey Feeding During Maintenance, Pregnancy, and Lactation: Effects on Body Weight, Milk Production, and Foal Growth
No full textWe evaluated the daily intake in donkeys during maintenance, late pregnancy, and early lactation. The growth curves of the foals in the first eight weeks of life and the milk production in lactating jennies were also investigated. Donkeys were separated into two groups: seven pregnant jennies (group 1: pregnant/lactating) and seven nonpregnant, nonlactating jennies (group 2). The groups were fed two different diets each. The feeding period for group 1 covered eight weeks before parturition and eight weeks postpartum. Group 2 was managed during the same time period (16 weeks). Diet 1 consisted of ad libitum hay, which was fed to group 1 during late pregnancy and to group 2 from weeks 1–8. Diet 2 consisted of the same ad libitum hay supplemented with 2 kg/head/day of concentrate, which was fed to group 1 during lactation and to group 2 from weeks 9–16. The daily dry matter intake (diet 1) was 2.56 kg/100 kg of body weight (BW) for nonpregnant jennies and 31% lower in the pregnant donkeys. In the lactating jennies, the total dry matter intake was similar to the nonpregnant group fed diet 2. The nonpregnant jennies lost 1.9% of their initial BW when fed diet 1, whereas they gained 8.4% of their initial BW when fed with diet 2. A weight loss was also found in the lactating donkeys. The foals more than doubled in their birth weight within two months

Quality of donkey mammary secretion during the first ten days of lactation
No full textThe physico-chemical characteristics and somatic cell count of donkey mammary secretion during the first ten days after foaling were analysed. During this period, a decreasing trend was observed for protein, dry matter and ash levels. The lowest values for lactose and pH were detected in the first hours (4.01 g 100 mL−1 of milk and 6.69 pH units), while the fat showed a peak (3.42 g 100 mL−1 of milk) at 6 h. The highest urea level was at 6 and 12 h (56.18 and 51.55 mg dL−1). Mineral levels changed during the experimental period, except for calcium, zinc and iron. Mean diameter of the fat globules and classes of fatty acids did not show significant differences; however, the n6/n3 ratio was influenced by day of lactation. In conclusion, the colostrum phase in donkeys lasts about 12–24 h, after which the secretion can be considered as transitional milk
