The lactation cycle of the dairy cow induces large changes in body fat and protein pools, which can be monitored through loin backfat (BF) and longissimus dorsi (LD) measurements. Data from two experiments (exp) using ...

We conducted an experiment to quantify the accuracy of methods based on n-alkanes and long-chain fatty alcohols for determining the diet composition of animals grazing complex swards. We cut forage from two indigenous ...

Pregnant Holstein heifers (450) and dry cows (417) within 3 weeks of calving (i.e., close up) were assigned to one of three groups. These groups were offered a low-CP (0.117 of DM) ration based on corn silage, alfalfa ...

The effect of adding water-soluble carbohydrate (WSC) on the microbial fermentation of fresh perennial ryegrass was examined in an in vitro RUSITEC system over two 10 day periods. Four treatment levels of WSC were used: a ...

To investigate the effect of red clover formononetin concentration on lamb growth rate and carcass characteristics, 20 lambs (10 ewe lambs and 10 wethers) were grazed on each of three forages : red clover with a high ...

Pastoral systems are some of the most fragile human ecosystems that exist and are under threat from the expansion of cultivation, changes in social patterns and climate change. These ecosystems are of major importance since ...

Two experiments were carried out to determine the effects of feeding grass silages differing in their water-soluble carbohydrate content, with or without red clover silage, on the efficiency of nutrient use. High-sugar ...

The objective of this experiment was to examine the residual effects of the level of concentrate feeding during the second gestation on performance in the second lactation. Forty-three Holstein-Friesian heifers that calved ...

Twenty-four multiparous Holstein-Friesian dairy cows in mid lactation were used in a 33 Latin square changeover experiment with three 4-week periods to investigate the effect of altering the ratios of red clover (RC) ...
