chemical composition and metabolizable energy of three camel browsed halophyte species (atriplex leucoclada, suaeda fruticosa, seidlitzia rosmarinus) were assessed and in vitro digestibility of dm (ivdmd), om (ivomd), ndf (ivndfd), adf (ivadfd) were determined using a completely randomized design. plant samples were collected based on camel's grazing patterns during the autumn-winter grazi...

Non-enzymatic browning was tested as a means of suppressing degradation of soybean meal (SBM) by ruminal microbes in five trials with in vitro ammonia release as the response criterion. Treatments imposed on SBM included reducing sugar source (xylose, glucose, fructose and lactose), reducing sugar level (1, 3 and 5 mol/mol SBM-lysine), pH (6.5, 8.5 and 10.0), dry matter (DM) content (65, 70, 75...

The effect of adding carbohydrate-rich feedstuffs to sweet potato leaves (SPL) on silage quality was studied using a total of 180 laboratory silos. Silage quality was assessed by changes of pH, dry matter (DM), crude protein (CP) and ammonia nitrogen (NH3-N). Pre-wilted SPL was mixed with cassava root meal (CRM), sweet potato root meal (SPM) or sugar cane molasses (Mo) at levels of 0, 30, 60 an...

We quanti®ed the effect of dietary non®ber carbohydrate (NFC) concentration (30, 35, 40, or 45% of DM) on in vitro digestion kinetics of neutral detergent ®ber (NDF) from alfalfa and corn silages at pH 5.8 or 6.8. The objective was to simulate the effect of diets differing in effective ®ber content on the optimal NFC-to-NDF ratio that resulted in maximal ®ber digestion. Ash-free NDF was determi...

The biomass productivity and nutrient composition of microalgae, such as Chlorella vulgaris, depend on the cultivation process content growth media. Thus, in this study aimed to investigate C. vulgaris cultivated fish dairy cattle wastewaters. Thirty wastewater samples (2.5 L) were collected from system production. Microalgae Erlenmeyer flasks containing 10 mL microalgae 1,790 under constant li...

OBJECTIVE Protein supplementation is costly and can result in excess nitrogen (N) excretion. The objective of this study was to evaluate the effects of feeding different levels of dietary protein on average daily gain, body size, rumen fermentation, and nitrogen excretion of 8 to 10 month-old Holstein heifers. METHODS Thirty-six Holstein heifers were divided into 12 blocks according to age (2...

High growth rates and rapid reproductive development associated decline in feed quality of sown tropical perennial grass pastures present management challenges for livestock producers. Conservation surplus forage as silage could be an effective tool. Experiments were conducted to evaluate the fermentation silages produced from grasses. Five species (Chloris gayana, Megathyrsus maximus, Panicum ...

Mir, P. S., Bittman, S., Hunt, D., Entz, T. and Yip, B. 2006. Lipid content and fatty acid composition of grasses sampled on different dates through the early part of the growing season. Can. J. Anim. Sci. 86: 279–290. In order to explore the value of herbage for the production of ruminant products with a high content of conjugated linoleic acid (CLA), a study was undertaken to determine the co...

Two experiments were conducted to determine the effect of corn processing method and corn wet distillers grains plus solubles (WDGS) level on steer performance and metabolism. In Exp. 1, 480 crossbred steer calves (314 +/- 18 kg of BW) were used in a finishing experiment with a randomized complete block design and a 3 x 4 treatment structure. Diets were based on dry-rolled (DRC), high-moisture ...
