The objective of this study was to evaluate Sargassum meal as feed for sheep through the measures of in vivo digestibility, dry matter degradability, pH, ammonia and volatile fatty acids in rumen. The Sargassum algae used in this experiment were collected at the end of spring, when they are more abundant, bigger, and have completed their reproductive cycle. Four tons (wet weigth) were collected...

1. In two experiments measurements were made of food intake, live-weight change, milk yield and milk composition in early lactation when dairy cows were given diets containing varying proportions of protein as fish meal (low rumen degradability) or as groundnut meal (high rumen degradability). In a preliminary trial measurements were also made with cows given supplements of either fish meal or ...

There is increasing interest in using locally produced protein supplements dairy cow feeding. The objective of this experiment was to compare rapeseed meal (RSM), faba beans (FBs) and blue lupin seeds (BL) at isonitrogenous amounts as grass silage cereal based diets. A control diet (CON) without supplement included the experiment. Four lactating Nordic Red cows were used a 4 × Latin Square desi...

Performance of ruminants is influenced by the proportion of nutrients in their daily feed intake. Protein and energy are the main determinants in the ruminant feed that can alter the animal’s performance. However, in developing countries ruminants are mainly fed on crop residues generally receiving only 62% of their crude protein (CP) requirements (Sarwar et al. 2002). Feeding ruminants accordi...

In this study, dry matter and crude protein in situ degradation data from different concentrate feeds were used to test the accuracy of effective degradability (ED) measures when using reduced ruminal incubation times compared with models based on seven or eight incubation times. The ED was estimated both with and without correction for nylon bag particle loss. The crude protein ED corrected fo...

Twenty-eight Holstein cows (4 with ruminal cannulas) were blocked by days in milk into 7 groups and then randomly assigned to 1 of 7 balanced 4 x 4 Latin square diet sequences. The diets contained [dry matter (DM) basis] 20% alfalfa silage, 35% corn silage, and 45% concentrate mainly from high-moisture corn and soybean meal. Diets differed in crude protein (CP) content and source of protein sup...
