ABSTRACT

The objective was to determine the effects of feeding prepubertal dairy heifers a high-energy diet for a duration of 0, 3, 6, or 12 wk on feed intake, growth, and fat deposition. We also used feed composition, daily intake, and body growth data to evaluate the nutritional model of the 2001 National Research Council (NRC) Nutrient Requirements of Dairy Cattle. Holstein heifers (age = 11 wk; body weight = 107 ± 1 kg) were assigned to 1 of 4 treatments (n = 16/treatment) designa...

Effects of Feeding Prepubertal Heifers a High-Energy Diet for Three, Six, or Twelve Weeks on Mammary Growth and Composition
Journal of Dairy Science ; ABSTRACT The experimental objective was to determine the effects of feeding prepubertal dairy heifers a high-energy diet for 3,6, or 12 wk on mammary growth and composition. Holstein heifers (age = 11 wk; body weight = 107 1 kg) were assigned to 1 of 4 treatments (n = 16/ treatment). The treatment
Short communication: Relationship between body growth and mammary development in dairy heifers
Journal of Dairy Science ; ABSTRACT Our objective was to determine if prepubertal rate of body weight (BW) gain, independent of diet, was related to mammary development of dairy heifers. Data from two studies recently conducted at Michigan State University were used to identify factors, within a dietary treatment group, that
Development of Replacement Heifers Using Programmed Feeding1
Professional Animal Scientist ; Abstract This experiment was conducted to determine the effects of diet and pattern of gain on reproductive performance. On November 24, 80 springborn Angus- and Brangus- sired heifers (BW = 230 23 kg) were allotted by breed and BW to one of four treatments (two replicates per treatment). Heifers
Calving heifers frequently under performing; PADDY BOYD, of Keenan, offers some important advice to farmers on setting targets in your heifer-rearing system.(Features)
The News Letter (Belfast, Northern Ireland) ; Byline: PADDY BOYD FIRST calving heifers generally comprise the largest single age group within the dairy herd. They have the potential to have the greatest effect on herd profitability and production, yet too frequently they are the most under-performing group in the herd. Achieving a calving age

Management Practices and Heifer Characteristics Associated with Early Lactation Somatic Cell Count of Belgian Dairy Heifers
Journal of Dairy Science ; ABSTRACT Associations between somatic cell counts (SCC) from heifers between 5 and 14 d in milk (DIM) and both herd-management practices and heifer characteristics were studied for 1912 heifers in 159 dairy herds in Flanders (Belgium). In higher-producing herds and in herds with an average calving

Prepartum Milking of Heifers Influences Future Production and Health
Journal of Dairy Science ; ABSTRACT Transition heifers face multiple stressors during the periparturient period, including first exposure to milking, that may adversely impact dry matter intake (DMI), reduce milk production, compromise immune function, and increase susceptibility to disease. It was hypothesized that reducing
CASE STUDY: A Chihuahuan Desert Brangus Breeding Program: Feed Efficiency, Metabolic Hormones, and Puberty in Heifers Sired by Bulls with Differing Expected Progeny Differences for Growth and Scrotal Circumference1,2
Professional Animal Scientist ; Abstract Our objectives were to evaluate growth, feed intake characteristics, metabolic hormones, and puberty in heifers from a Chihuahuan Desert Brangus breeding program. Heifers were of similar age and progeny of sires (n ≥ 7 heifers per sire) with expected progeny difference [EPD
Heifers yield good numbers
The Press ; A nucleus herd of top holstein- friesian heifers at an Ashburton farm averaged more than 400 kilograms of milksolids in their first season of milking. The herd of 22 heifers was brought together from around New Zealand by holstein-friesian farmers and Livestock Improvement for the Discovery
