Autor: E K, Cook, M E, Garcia-Ascolani, R E, Ricks, S K, Duckett, G C, Lamb, N, DiLorenzo, N M, Long

Publikováno v: Journal of animal science. 95(7)

The objective of this study was to determine if supplementation frequency of rumen-protected fat (RPF) influences circulating serum concentrations of fatty acids (FA), NEFA, and urea nitrogen in beef heifers and lactating cows. In Exp. 1, 12 early ge

The effect of supplementing rumen undegradable unsaturated fatty acids on marbling in early-weaned steers

Autor: K S, Mangrum, G, Tuttle, S K, Duckett, G S, Sell, C R, Krehbiel, N M, Long

Publikováno v: Journal of animal science. 94(2)

The objective of this study was to determine if supplementation with a rumen undegradable unsaturated fatty acids (FA) source improved marbling deposition in early-weaned steers. All steers (Angus, = 23; Angus × Hereford, = 24) were weaned at 150 ±

Maintenance energy requirements of beef cows and relationship with cow and calf performance, metabolic hormones, and functional proteins

Autor: M J, Cooper-Prado, N M, Long, M P, Davis, E C, Wright, R D, Madden, J W, Dilwith, C L, Bailey, L J, Spicer, R P, Wettemann

Publikováno v: Journal of animal science. 92(8)

Gestating Angus, nonlactating, spring-calving cows were used to determine variation in maintenance energy requirements (MR); to evaluate the relationship among MR and cow and calf performance, plasma concentrations of IGF-I, T4, glucose, insulin, and

Maternal obesity upregulates fatty acid and glucose transporters and increases expression of enzymes mediating fatty acid biosynthesis in fetal adipose tissue depots

Autor: N M, Long, D C, Rule, M J, Zhu, P W, Nathanielsz, S P, Ford

Publikováno v: Journal of animal science. 90(7)

Maternal nutrient restriction leads to alteration in fetal adipose tissue, and offspring from obese mothers have an increased risk of developing obesity. We hypothesized that maternal obesity increases fetal adipogenesis. Multiparous ewes (Columbia/R

Effects of early- to mid-gestational undernutrition with or without protein supplementation on offspring growth, carcass characteristics, and adipocyte size in beef cattle

Autor: N M, Long, C B, Tousley, K R, Underwood, S I, Paisley, W J, Means, B W, Hess, M, Du, S P, Ford

Publikováno v: Journal of animal science. 90(1)

Angus × Gelbvieh cows with 2 to 3 previous pregnancies were used to evaluate effects of maternal nutrient restriction on offspring adipose tissue morphology at standard production endpoints. At 45 d after AI to a single sire, pregnancy was confirmed

Relationship of ruminal temperature with parturition and estrus of beef cows

Autor: M J, Cooper-Prado, N M, Long, E C, Wright, C L, Goad, R P, Wettemann

Publikováno v: Journal of animal science. 89(4)

Spring-calving Angus cows (n = 30) were used to evaluate changes in ruminal temperature (RuT) related to parturition and estrus. Cows were synchronized and artificially inseminated with semen from a single sire. Temperature boluses were placed in the

Maternal obesity and increased nutrient intake before and during gestation in the ewe results in altered growth, adiposity, and glucose tolerance in adult offspring

Autor: N M, Long, L A, George, A B, Uthlaut, D T, Smith, M J, Nijland, P W, Nathanielsz, S P, Ford

Publikováno v: Journal of animal science. 88(11)

We evaluated the effects of preconception and gestational obesity in the ewe on offspring growth, metabolism, and glucose homeostasis. From 60 d before conception through parturition, multiparous ewes were fed 100% (control; n = 8) or 150% (obese, OB
