Market availability and price of conventional feedstuffs are variable, making imperative to explore alternative feedstuffs. Cassava (Manihot esculenta) is a starchy tuber that can be a potential feedstuff for swine. Three sample type (combinations of cassava parts): 100% tubers (T100), 50% tubers and 50% leaves (T50), and 25% tubers and 75% leaves (T25) were ensiled over three periods [fresh (M...

This work aimed to determine and compare the effect of elevation season on productivity nutritive value pastures in Azores (Terceira Island). Forage was collected analysed for dry matter (DM), crude protein (CP), neutral detergent fibre (NDF), acid (ADF), lignin (ADL), ether extract (EE), mineral ash (Ash), digestibility (DMD) organic (OMD). The net (NP) higher low pasture A (1.80 g m?2), lower...

Studies at the University of Reading (UK) compared silage quality, feed intake and digestibility of maize silage with maize±sun ̄ower (MS), maize±kale (MK) and maize±runner bean (MRB) silage, when sun ̄owers, kale and runner beans represented 26, 7 and 16% of total silage dry matter (DM). All intercrop silages had higher crude protein values (MS, 137 g kgÿ1, MRB, 120 g kgÿ1, MK, 105 g kgÿ1) than ...

Andropogon gayanus is an important grass due to its high biomass production, drought tolerance and favorable growth on low fertility acidic soils. Currently, there is little research on the impact of growth stage on the nutritional quality or the degree of CH4 production that may arise from this forage during ruminal fermentation. The objectives of this study were to determine the effects of re...

The experiment was conducted to evaluate losses and nutritive value of elephant grass silage containing increasing levels of cottonseed meal. The experimental design was completely randomized, with five treatments: 0, 7, 14, 21 and 28% inclusion of cottonseed meal, and four replications. The material was chopped and packed in PVC silos and stored for 80 days. The pH and dry matter (DM), crude p...

The goal of making silage is to preserve as much as the original nutritive value of the crop as possible so that it can be fed throughout the year. Many factors affect the fermentation process and unfortunately the end result is not always good. Poor fermentations can lead to excessive run off, loss of nutrients, and production of spoiled silage that is no longer fit for feeding and must be dis...

introduction amaranth, genus amaranthus, belongs to the amaranthaceae family and includes more than 60 species (28). amaranth forage, is distinguished by high yield performance of up to 70 t/ha (30). plant maturity was found to affect neutral detergent fiber (ndf), acid detergent fiber (adf), lignin, cp and nitrate content of amaranth forage (27). several studies (21, 27, 29) have shown that the ...

The objective of this study was to investigate the effects of increasing maturity of whole-plant corn at harvest on CH4 emissions by dairy cows consuming corn silage (CS) based diets. Whole-plant corn was harvested at a very early [25% dry matter (DM); CS25], early (28% DM; CS28), medium (32% DM; CS32), and late (40% DM; CS40) stage of maturity. In a randomized block design, 28 lactating Holste...

Total mixed rations containing 31 or 25% NDF were supplemented with 0 or .5 kg/cow per d Ca salts of fatty acids to study the effect of adding Ca salts of fatty acids to diets that differed in NDF content. Rations were fed for ad libitum intake to 12 early to midlactation Holstein cows in a replicated 4 x 4 Latin square design with a 2 x 2 factorial arrangement of treatments. No significant int...
