“…According to the US Food and Drug Administration, milk pasteurization should be carried out at 62.8 °C for 30 minutes, 71.6 °C for 15 seconds, 88.4 °C for 0.1 seconds, 95.6 °C for 0.05 seconds, or 100 °C for 0.01 seconds (flash pasteurization) [3]. The nutritional value of milk is widely reported in several pieces of research [4,5,6,7]. However, raw milk is susceptible to microbial contamination.…”

Solar pasteurization, as a means of treating milk in remote rural areas without electrical power, is based on using solar energy to thermally inactivate pathogenic microorganisms at temperatures below the boiling point to maintain or improve milk quality. A solar milk pasteurizer of flat‐plate water‐heating glass acting as the solar collector, connected to a stainless-steel cylindrical milk vat, was constructed and evaluated in Navrongo, in the tropical savanna zone of Ghana, West Africa. The novel approach taken in this project is to integrate the solar collection and heat exchanger into a single unit using materials and fabrication techniques readily available in the developing world. The vat comprises a 1.5 mm thick stainless steel cylindrical tank, a 2.2 cm wide hot water jacket, and an outer layer of 5.0 mm thick aluminium foil insulation. Hot water produced by the collector was used for pasteurizing milk. The optimum quantity of milk that this device could pasteurize under the study conditions was 8 L. The device could pasteurize raw milk to a maximum temperature of 74 °C at 14:00 h GMT. The ambient temperature during the pasteurization ranged from 30 °C to 43 °C. The microbial analysis before and after the pasteurization was done, and the result shows that the total bacteria count before pasteurization was 6.6x106 log CFU/mL per unit volume, and the total bacteria count after pasteurization was 1.0x102 log CFU/mL. By acceptable standards, the total bacteria count after pasteurization is within a safe range for consumption, and coliform counts were negative. The solar milk pasteurization system is cost-effective. Hence, it is appropriate for milk producers in arid pastoral areas without electricity to adopt the solar pasteurizer as an alternative to firewood as a fuel source for milk pasteurization. This approach can potentially create a cottage industry that may also play a crucial role as a water treatment technology that will improve the health of rural populations.

“…On the basis of biochemical, isotopic and osteo-archaeological data, Vigne (2008) argued that herd animals were managed for milk production at early Neolithic sites in Europe and the Middle East, and that milk exploitation was one of the original motivations behind animal domestications. Milk has high nutritional value including various essential vitamins and minerals (Graulet 2014;Yvan Chouinard and Girard 2014). Vigne and Helmer (2007:24-28) examined agemortality profiles for sheep and goats from three MPPNB and nine LPPNB sites in the northern and southern Levant.…”

The aim of this study was to investigate the effects of replacing different ratios of basal diets with hydroponically barley seedlings (HBS) on the serum biochemical indexes and growth performance of lambs. It provides a theoretical basis for the use of HBS in ruminant health and scientific feeding management. In total, 30 ewes were randomly categorized into six groups (two control groups, 4 treatment groups, and 8 replicates in each group). All experiments were conducted under the same feeding and management conditions, on this basis the control group was CK1 and CK2 groups, which CK1 group added 15% corn silage, the treatment groups replacing 5% (group A), 10% (group B), 15% (group C) and 20% (group D) of the basal diet (dry matter basis) with HBS, and the experimental period lasted for 36 days, and the lambs were lactating with their mothers throughout the experimental period. Key results. The contents of total protein (TP), albumin (ALB), milk fat percentage and total solids (TS) in group C were significantly higher than CK1 and CK2 groups (p < 0.05) in milk samples; malondialdehyde (MDA) content in groups A and C was significantly lower than groups CK1 and CK2 (p < 0.05), alanine aminotransferase (ALT) and azelaic transaminase (AST) contents in groups A and B were significantly higher than CK1 group (p < 0.05), TC content in groups A and D was significantly higher than CK1 and CK2 groups (p < 0.05), high-density lipoprotein (HDL-c) content in group D was significantly higher than CK1 and CK2 groups (p < 0.01) in blood samples; Body height in C group was significantly higher than CK2 group (p < 0.05), ear width in group B was significantly higher than CK1 group (p < 0.05). In conclusion, under the conditions of this experiment, HBS instead of 5–15% of the basal diet could improve the milk quality of lactating Hu ewes and alleviate the oxidative stress of the body.
