AbstractFull Text

The study was conducted in Osorno Chile, in order to assess the effect of castration on average daily gain of weaned calves during the backgrounding phase. The study considered a total of 20 weaned calves of a beef biotype whose average live weight was 189.5 kg (±4.3 SEM). Two groups of 10 animals...

AbstractFull Text

The ingestive behaviour of dairy cows grazing L. perenne cv. Quartet with different levels and types of endophyte was evaluated over a 5-month period (Spring-Autumn). The trial was carried out in Osorno, on pastures of L. perenne cv. Quartet with: Low levels of endophytes (BES); endophyte AR1; and...

Abstract

The high content of crude protein (CP) of pastures in southern Chile creates a nutritional imbalance that results in large amount of nitrogen (N) being excreted into the environment. Two regression equations and a dynamic model, available from the literature, were utilized to simulate the N use...

AbstractFull Text

The objective of this study was to determine if the supplementation with two carbohydrate sources that have different degradation rates, reduces the ammonia production by ruminal bacteria by increasing the nitrogen capture in dairy cows grazing high protein contents pastures. Four dairy cows fitted ...
