Genomic breeding programs - a large step forward for low-input dairy cattle breeding? Organic Eprints
Simianer, H.; Bieber, A..
This technical note gives an overview of the history of dairy cattle breeding, introduces the basic concept and outlines the consequences of genomic breeding strategies especially with regard to functional traits. First results of the LowInputBreeds project in the area of dairy cattle breeding are presented, and limitations and ethical implementations are discussed. Finally, recommendations are given how farmers, especially in the low input sector, should implement the new approach.

Comparison of traditional and genomic breeding programs for organic and low input dairy cattle accounting for traits relevant in different macro-climatic zones Organic Eprints
Frevert, H.; Yin, T.; Simianer, H.; König, S..
In the past decade, successful selection on production traits for dairy cattle has greatly increased milk production. Recently, selection indices for female fertility were gradually and increasingly introduced into the overall breeding goals for dairy cattle (Miglior et al., 2005). As a by-product of fermention in ruminants, enteric methane emissions (ME) should also be controlled and mitigated due to their contribution to global warming (Forster et al., 2007) and as a cause for inefficient use of dietary energy. Moderate heritabilities ranging between 0.30 and 0.35 for predicted and real measurements of ME were reported...

Occurrence of Campylobacter jejuni and Campylobacter coli and their biotypes in beef and dairy cattle from the south of Chile BJM
Fernández,Heriberto; Hitschfeld,Marianne.
The prevalence of Campylobacter jejuni and Campylobacter coli and their biotypes in beef and dairy cattle from the South of Chile was established. Campylobacter were statistically more prevalent among beef cattle (35.9%) than among dairy cattle (21.3%), being C. jejuni the species most frequently isolated.

Opportunities and challenges for integrating dairy cattle into farms with certified organic pineapple production as perceived by smallholder farmers in Central Uganda Organic Eprints
Nalubwama, Sylvia; Kabi, Fred; Vaarst, Mette; Kiggundu, Muhammad; Smolders, Gidi.
A study was conducted in 2013 to assess opportunities and challenges of integrating dairy cattle into organic pineapple production in Uganda. Thirty organic pineapple farmers were interviewed using a semistructured questionnaire. The main dairy cattle management systems were tethering (73%) and zero grazing (27%). Average landholding was 1.74 ± 1.06 and 3.75 ± 2.70 ha for zero grazing and tethering systems, respectively. All farms were diversified with various livestock such as cattle, goats, sheep, pigs, and chickens and crops including pineapples, maize, coffee, bananas, beans, sweet potatoes, and cassava. The level of...

Occurrence of antibodies to Neospora caninum and Toxoplasma gondii in dairy cattle from the northern region of the Paraná State, Brazil Arq. Bras. Med. Vet. Zootec.
Ogawa,L.; Freire,R.L.; Vidotto,O.; Gondim,L.F.P.; Navarro,I.T..
Three-hundred and eighty-five serum samples were taken from dairy cows on 90 farms in 12 counties from the northern region of the Paraná State, Brazil. The samples were analyzed by IFAT for the detection of anti-Neospora caninum and anti-Toxoplasma gondii IgG antibodies. Forty-five (12%) samples were seropositive to N. caninum, while 102 (26%) samples were seropositive to T. gondii. Only four animals were seropositive to both coccidia. No significant difference was observed between the N. caninum serology and any of the variables studied, such as dairy cattle management, milk production, reproductive problems, feeding, and presence of dogs, cats and rodents. These data suggest that...
