The risk of unintended deforestation from scaling sustainable livestock production systems por Castro-Nuñez, Augusto Carlos, Buriticá, Alexander, González, Carolina, Villarino, Maria Eliza J., Holmann, Federico, Pérez Marulanda, Lisset, Río Duque, Martha Lilia del, Sandoval, Danny, Eufemia, Luca, Löhr, Katharina, Durango, Sandra, Romero Sánchez, Miguel Antonio, Lana, Marcos A., Sotelo, Steven, Rivera, Ovidio, Loboguerrero Rodriguez, Ana María, Quintero, Marcela

“…Results showed a change in herd composition, with fewer males and more cows/heifers, suggesting a shift toward specializing in milk production, which, with the appropriate environmental incentives and safeguards, would unlikely broaden deforestation. …”

Single nucleotide polymorphisms in candidate genes and their relation with somatic cell scores in Argentinean dairy cattle por Nani, Juan Pablo, Raschia, Maria Agustina, Carignano, Hugo, Poli, Mario Andres, Calvinho, Luis Fernando, Amadio, Ariel

“…In this work, we evaluated a set of single nucleotide polymorphisms (SNPs) in candidate genes for health and production traits, and determined their association with the somatic cell score (SCS) as an indicator of mastitis in Argentinean dairy cattle. We evaluated 941 cows: Holstein (n = 677) and Holstein × Jersey (n = 264) crossbred, daughters from 22 bulls from 14 dairy farms located in the central dairy area of Argentina. …”

Bovine colostral cells : the often forgotten component of colostrum por Gonzalez, Diego, Dus Santos, Maria Jose

“…In addition to maternally derived antibodies, colostrum contains immunologically important cytokines and a large number of maternally derived (materBovine nal) leukocytes, which collectively contribute to the immunoprotection of the neonate.13–16 Although the role of colostral antibodies in the protection of neonates against disease has been well documented,17–20 the role of colostral cellular components in passive immunity is less well understood.21–28 In the early 1970s, researchers began to suggest that maternal lymphocytes in colostrum were primed antigen-responsive cells that, when ingested soon after birth, penetrate the permeable intestinal wall and provide transient local or systemic cell-mediated immunity, the breadth of which reflects the antigenic exposure of the cow from which the colostrum was acquired.…”

Improvements in milking management through imitation of calf behaviour por Eriksson, Ida

“…Approximately 20% of the milk within the udder of a cow is stored in the cistern and immediately available for milk removal, while activation of the milk ejection reflex is required for removing the remaining milk stored in the alveolar compartment. …”

Isoflavone sources and bioavailability por Gatchell, Sara

“…But only approximately 30-50% of the population are so called “equol-producers” and for the other half soy may not be an optimal isoflavone source and instead bovine milk may serve as an alternative and/or additional dietary source, as isoflavone metabolites have been traced in cow’s milk.…”

Coxiella seroprevalence and risk factors in large ruminants in Bihar and Assam, India por Shome, R., Deka, Ram Pratim, Milesh, L., Sahay, S., Grace, Delia, Lindahl, Johanna F.

“…On an individual animal level, 14.1% were seropositive, with higher prevalence among buffaloes than cows (28.0% versus 13.6%). Out of the seropositive animals, 10.6% had aborted during the last three years, and 37.5% had experienced problems with repeat breeding: both higher than in non-seropositive animals. …”

Availability and use of mycotoxin binders in selected urban and peri-urban areas of Kenya por Mutua, Florence K., Lindahl, Johanna F., Grace, Delia

“…One option for reducing aflatoxin concentration in cow milk is addition of mycotoxin binders to animal feeds, but little is known about this practice in the smallholder dairy systems in developing countries. …”

The Efficacy of the Mazzican for milking, transportation and improving bacteriological quality of milk in the smallholder dairy value chain in Tanzania por Kurwijila, Lusato R., Mboya, N., Laizer, M., Omore, Amos O.

“…During the preliminary period milk samples were taken directly from jerry cans and farmers were asked to report observed cases of cows with signs of abnormal milk. A higher total plate count was observed in milk samples taken from the smallholder dairy farmers’ jerry cans (1.19 x 106 cfu/ml) than traditional pastoralists jerry cans (4 x 105 cfu/ml), and Mazzican for smallholder farmer (3.6 x 105 cfu/ml). …”
