The objective of this study was to evaluate the best level of inclusion of cactus pear in the ensiling of elephant grass Brazil seeds (BRS) capiaçu (Pennisetum purpureum), its effects on fermentative characteristics; and nutritional value. Experimental treatments consisted of BRS capiaçu grass silage with five levels of inclusion of cactus pear (0, 5, 10, 15 and 20% inclusion as fresh ...

We evaluated the effect of supplementing typical dairy diets with yeast and fibrolytic enzymes on dairy cow performance. Twentyfour Holstein cows were used to evaluate the effects of yeast (Procreatin-7, a live culture of Saccharomyces cerevisiae) and various amounts of FP800 (a fibrolytic enzyme mixture) on lactation performance. Treatments were arranged in a 4 × 2 factorial design consisting ...

An experiment was conducted to investigate the effect of feed supplementation on chemical composition of Jinding duck’s egg. A total of 180 physically sound eggs were randomly collected in each time at 50% and 75% level of egg production of the ducks. Significant difference was observed for dry matter content of egg albumen of ducks fed on different diets at 50% level of egg production (P<0.01)...

This study was conducted at the Atat niversity farm in Erzurum over 2 years (2004-2005) to evaluate the effects of phosphorus doses and application season on the dry matter production, botanical composition and crude protein, ADF and NDF content of an alsike clover-dominated natural hay meadow. The experiment was planned in a Randomized Complete Block Design with split-plot arrangement of appli...

Distillers grains with solubles (DGS) is the major coproduct of ethanol production, usually made from corn, which is fed to dairy cattle. It is a good protein (crude protein, CP) source (>30% CP) high in ruminally undegradable protein (approximately 55% of CP) and is a good energy source (net energy for lactation of approximately 2.25 Mcal/kg of dry matter). The intermediate fat concentration (...

The effect of varying dry matter availability on the conversion of dry matter resources to weight of calf at weaning was evaluated for nine breeds of cattle; Angus, Braunvieh, Charolais, Gelbvieh, Hereford, Limousin, Red Poll, Pinzgauer, and Simmental were recorded for 5 yr. Within each breed, four cows were assigned to each of four feeding levels of dry matter intake: 58, 76, 93, or 111 g of D...

Corn can produce high dry matter yields with one harvest. Corn is a good crop to recycle nutrients from manure and maintain water quality. Corn silage is easily ensiled and generally results in palatable forage with relatively consistent quality and higher energy content than other forages. Corn silage production requires less labor and machinery time than other harvested forages. Thus, the cos...
