FEEDING A FLAX SEED SUPPLEMENT TO DAIRY COWS. | Research in the past 50 years has shown that the general health of dairy cows can be improved by higher post-ruminal delivery and absorption of poly-unsaturated fatty acids (PUFA), especially omega-3 (n-3) acid. Since flaxseed contains a high concentration of n-3, the objective of the authors cited below was to evaluate the effects of feeding the flaxseed-based supplement LinPro on the production and health of mid-to-late lactation multi-lactation Holstein cows. |

NITRATE ADDITION AS A METHOD TO MITIGATE METHANE IN DAIRY COWS. | There is not much information on the effect of dietary nitrate addition as a method to mitigate methane in grazing dairy cows. Therefore, the authors cited below did a study aiming to investigate the effect of nitrate addition on daily enteric methane emissions, production performance and rumen fermentation of multi-lactation Jersey cows grazing perennial ryegrass pasture, which contained about 7.3 g nitrate per kg dry matter (DM). |

SUPPLEMENTATING DAIRY COWS WITH MORINGA LEAF MEAL. | Vitamins, mostly A, C and E, and minerals, such as selenium, copper and zinc, have been used to mitigate oxidative stress. However, in confined systems, the risk of over- or undersupplying micro elements is high, hence the overproduction of pro-oxides is common. Additionally, in semi-intensive feeding systems, trace elements, particularly antioxidant supplementation, are limited owing to restricted or lack of supplementation. Therefore, research focus has shifted to exploration of the potential of natural antioxidants in improving animal production and health. |

PRIORITIES TO BE ADDRESSED IN THE INDUSTRY TO SUPPORT SUSTAINABILITY. | Competitiveness is a function of efficiency, market access (broadening of the market of dairy products is a primary goal) and sustainability. In addition to volatility, structural and consumer needs of markets which with up-to-date information can be addressed only partially, sustainability is progressively also influenced by issues which can be categorized within the three P concepts: Productivity (economic focus), People (sociological focus) and Planet (environmental stewardship focus). |

CAN WE USE MOLECULAR DETECTION METHODS TO INDENTIFY LIVER FLUKE AND ITS INTERMEDIATE HOSTS IN THE ENVIRONMENT? | Fasciolosis, or liver fluke infection, results in reduced production and economic losses in dairy cattle and other livestock species. The lifecycle of the fluke, Fasciola hepatica, involves lymnaied snails as the intermediate host and depends on the development and survival of larval stages both in the snail and in the environment. This implies that the infection risk will depend on pasture and other areas harbouring the snails, as well as climatic and other environmental influences. |
|||
IS THERE A RELATIONSHIP BETWEEN COW CONDITION AND COLOSTRUM EFFICACY? | Weight loss of cows during the dry period has several consequences, mostly associated with reproduction and subsequent lactation. What is not generally considered is the success of colostrum production and its quality. This formed the basis of the study by the authors cited below. |

MASTITIS PATHOGEN DISTRIBUTION IN SA: 2013 COMPARED WITH 2008. | In recent years, there has been an increase in the prevalence of environmental pathogens as a cause of intra-udder infections (IUI) in dairy cattle. Increases in prevalence could potentially be ascribed to improved control methods for contagious pathogens, difficulties in controlling pathogens from an environmental reservoir and the ability of Streptococcus uberis and Escherichia coli to persist in the udder. |

BULK TANK TESTING CAN ADD VALUE TO UDDER HEALTH TESTING AND SAFE MILK. | Routine bulk tank milk testing is an adjunct to monitor milk quality and udder health as total bacterial counts, and enumerating psychrotropic and thermoduric bacteria counts, may provide useful information on the cleanliness of milking procedures and equipment, the effectiveness of milk cooling and system sanitation. Also, differential bacterial counts may provide information on the occurrence of and changes in mastitis pathogens. |

MILK PRODUCTION AND CONSUMPTION TRENDS IN EASTERN CAPE COMMUNITIES. | The production and consumption of milk in the communal areas of the Eastern Cape Province is largely unknown. Although production is expected to be modest, there should be potential in the sector for purposes of household and commercial milk production. Consumption trends in these communities, with a population size of roughly 4 million people, may influence general milk consumption trends in the country. The aim of the study by the authors referenced below was to collect baseline information which could inform future research. |

HAVE WE BENEFITTED FROM THE DAIRY GENOMICS PROGRAM? | A RP of 1186 and a validation population of 128 was established, enabling the inclusion of genomic information in estimation of breeding values, based on the INTERBULL verified Logix Genetic Evaluations and a Single-Step approach, using Mix99, to present the industry with GEBVs. These GEBVs reflect the expression of genes in the SA environment, based on the genetic variation and gene frequencies of the SA Jersey population. |
