Camels subsist and produce milk in desert pastures not utilized by other domesticated herbivores. Developing the camel milk industry can improve the economy of desert inhabitants. To comply with sanitary ordinances, camel milk is pasteurized by procedures specified for bovine milk. It is widely accepted that milk composition might affect bacterial thermal death time (TDT). Camel and bovine milks markedly differ in their chemical composition, yet data regarding TDT values of bacteria in camel milk is missing. As a first step toward developing specific heat treatments appropriate for camel milk, TDT curves of Escherichia coli in artificially contaminated camel and cow milks have been compared. Heating the milks to temperatures ranging from 58 to 65°C yields similar thermal death curves and derived D- and z-values. These findings suggest that, in this temperature range, E. coli might behave similarly in bovine and camel milk. Additional TDT studies of various pathogenic species in camel milk are required before establishing pasteurization conditions of camel milk.

If gross composition of camel milk is roughly comparable to cow milk, fine composition shows significant differences explaining potential health benefit for regular consumers. The main particularities of camel milk are (1) better atherogenicity index thanks to its higher proportion of mono-unsaturated and polyunsaturated fatty acids compared to other milks, (2) different proportion of caseins than cow milk leading to difficult clotting, (3) lack of β-lactoglobulin, often responsible for cow milk allergy, (4) slightly higher concentration in antibacterial and immunity support proteins with higher bio-activity than in other milk, (5) presence of WAP (whey acidic protein) and PGRP (peptidoglycan-recognition protein) not available in cow milk, (6) probable efficient insulin for supporting better glycemia regulation, (7) better metabolization of lactose leading to lower intolerance in consumers, (8) richness in sodium and iron compared to other milks, and (9) contrasted values of vitamins (less vitamins B, high quantity of vitamins C and D). This chapter explores camel milk composition and nutritional value.

Abstract The aims of this survey were to determine the frequency of anti-Toxoplasma gondii and anti-Neospora caninum antibodies and to identify the risk factors associated with seropositivity among buffaloes in the state of Paraíba, Brazil. This survey included 136 buffaloes belonging to 14 herds. To detect anti-T. gondii and anti-N. caninum antibodies, the indirect fluorescent antibody test (IFAT) was used. Among the 136 samples analyzed, 17 (12.5%) were positive for anti-T. gondii antibodies with titers ranging from 64 to 1,024, and 26 (19.1%) for anti-N. caninum with titers from 200 to 1,600. Animals seropositive for both T. gondii and N. caninum were found in 10 of the 14 herds (71.4%). Semi-intensive management systems (odds ratio = 2.99) and presence of pigs (odds ratio = 4.33) were identified as risk factors for T. gondii and N. caninum, respectively. It can be suggested that T. gondii and N. caninum are widespread in buffaloes in Paraíba, and that additional surveys are needed in order to ascertain the importance of these agents for this species and for pigs, and the influence of the farming type on occurrences of seropositive animals.

Four management systems were evaluated in a six-year study to control nematodes in a turnip-corn-pea annual cropping System on plots of Tifton loamy sand naturally infested with Meloidogyne spp. (about 90 % M. incognita and 10% M. hapla), Pratylenchus spp. (about 65% P. scribneri, 25% P. brachyurus, and 10% P. zeae), Paratrichodorus minor and Criconemella ornata. Turnip (Brassica campestris subsp. rapifera) supported low numbers of all nematodes. 'Pioneer 3369A' corn (Zea mays) supported greater numbers of all nematodes than 'Funks G-4507'. Population densities of Meloidogyne spp. juveniles (J2) were suppressed below 80 per 150 cm3 of soil by 98 % methyl bromide + 2 % chloropicrin and 20 % methyl isothiocyanate + 80 % chlorinated C3 hydrocarbons on turnip and corn, and increased rapidly on 'Pinkeye purplehull', but not on a resistant cultivar, 'Worthmore' pea (Vigna unguiculata). Population densities of other nematodes were not affected by cultivar of pea or the nematicide, ethoprop. Fenamiphos was more effective than ethoprop in suppressing nematode population densities. Increases in crop yield in the intensive management system ranged from 4% to 52% over untreated controls.

This chapter focuses on the potential health benefits of camel milk including angiotension I-converting enzyme-inhibitory, anti-cancer and antioxidant activities, antidiabetic, antimicrobial and hypoallergenicity effects. The bioactivity of oligosaccharide, conjugated linoleic acid and D-amino acid in camel milk is provided. The proposed mechanisms behind these bioactive components and potential health claims are explained. This chapter also describes camel milk composition, nutritional value, production and population. The current available information in the literature on camel milk is not abundant. More research is needed to give better understanding on functional properties of camel milk.

Wang, Z., Ma, B.-L., Gao, J. and Sun, J. 2015. Effects of different management systems on root distribution of maize. Can. J. Plant Sci. 95: 21–28. Characterization of root distribution in maize (Zea mays L.) is important for optimizing agronomic management to match crop requirements, while maximizing grain yield, especially under intensive management. The objectives of this study were to examine the differences in maize root distribution between two management systems and to identify root-related factors that could be adjusted for further yield improvement. A 4-yr field experiment examined maize root distribution under two management systems: farmers’ practices (FP: low plant density, unbalanced fertilization) and high yield strategies (HY: high plant density, sufficient fertilization). Root mass distribution within the soil profile was more restricted horizontally within 10 cm from the stalk base and vertically below 20 cm in HY compared with FP. HY had a greater proportion of fine roots (diameter ≤ 0.5 mm) and more roots per 100 kernels than FP. However, per-plant root weight was not significantly affected by type of management system. Yield was positively correlated with total root number and the ratio of root mass below 20 cm to total root mass. Our data indicate that HY maize overcame the negative effect of crowding stress by producing more roots with smaller root diameters, and maize root systems became narrower and were distributed deeper under intensive management compared with traditional famers’ practices.
