Milk Production Comparisons: Domestic & F-1 Yearlings from the Imported French Semen – 2019 – Laurel Kieffer DSANA Production Improvement Project, Tom Clark DSANA Genetic Improvement Committee, Mike Thonney Professor of Animal Science Cornell University. A presentation that demonstrates the differences in milk production from the first F1 ewes born from imported French Semen. It incentivizes both the semen importation program and DSANA’s Production Improvement Program.
Current trends of the Spanish Assaf Sheep / Genetic Improvement Program - 2018 - Overview of the genetic improvement of dairy traits in the Assaf breed over the last 25 years. An intensive selection and breeding program employed by the Spanish Assaf Association has resulted in major improvements in the breed’s milk yield, lactation length, and udder conformation. The breed improvement program has also included selection for milk composition and somatic cell count.
Nutritional Management of Reproduction in Dairy Sheep - 2018 - A small ruminant dairy vet and sheep dairy owner in California lays out how to managing ewe nutrition to maximize reproductive efficiency – improving ovulation rate, conception rate, pregnancy to term, and lambing rate. The relationship of Body Condition Score with reproduction. The impact of feed characteristics, feed quality, and feed mineral profile on reproduction.
Management of AI Reproduction in Dairy Ewes - 2018 - A small ruminant dairy vet and sheep dairy owner in California explains how to improve conception rates for ewes bred via laparoscopic AI. Specifics on reducing internal and external stressors, from 60d prior to insemination date, to 45d after insemination date. Handling and management of ewes during LAI process. Factors that affect semen quality.
