The digestible protein requirements of lactating ewes were studied with Chios 3 ewes during the declining state of lactation in two nitrogen balance and three feeding trials. A 60 kg ewe producing 1.0 or 2.0 kg milk of 6% protein and maintaining weight equilibrium, required 134 and 230 g digestible protein daily, respectively. These requirements were obtained with ewes receiving 110 Kcal metabo...

Plant Species and Variety Forage quality refers to digestible nutrient content (i.e., energy, protein), palatability and digestibility of the forage plant. Legumes (alfalfa, medics, cloves, vetch) are the highest quality group of forage grown in pastures. They are high in protein, energy (digestibility), and minerals. They also “fix” nitrogen fertilizer, making them very economical to grow. Inc...

ABSTRACT The objective of this study was to evaluate the effect replacing Tifton 85 hay with maniçoba in diets based on spineless cactus nutrient intake and digestibility, ingestive behaviour ruminal parameters confined sheep. In order do this, eight male sheep cannulae were used, distributed across four levels (0, 333, 666 1.000 g kg-1 dry matter) replacement a double Latin square experimental...

The objective of the present study was to determine dietary effect different growth stages rapeseed (Brassica rapa L.) on nutrient intake and digestibility, nitrogen balance, rumen fermentation kinetics in sheep. Four treatments were utilised. A basal control diet based alfalfa hay, oat soybean meal corn grain. Then hay replaced with 300 g/kg DM forage harvested at three stages: Vegetative, Flo...

the present study was conducted on efficiency of utilization of dietary energy for milk production in lactating crossbred cattle. 18 lactating crossbred cattle of early to mid-lactation, approximate body weight (375.39±23.43 kg), milk yield, parity and stage of lactation were divided into three groups of six animals each and were fed 0, 50 and 100% diammonium phosphate (dap) in the mineral mixt...

Two experiments were conducted to determine the effect of EM on the consumption, nutritive value and digestibility of corn forage (Zea mays L.) processed into corn silage after harvesting at two growth stages. Stage 1 silage contained 25 percent dry matter and stage 2 silage, harvested nine days later, contained 37 percent dry matter. The first experiment involved feeding trials with sheep and ...

The current concern of nutrient loading waterways and soils from livestock manure has increased awareness of methods to reduce excess nutrient excretion. The initial methods for nutrient reduction are simple diet manipulations to feed nearer the requirement of the pig. Further modifications have been made to increase digestibility of feedstuffs. The use of genetically modified corns and additio...

The main goal in formulating animal feeds is to supply nutrients in amounts and relative proportions that optimize performance. This is particularly important with respect to amino acids (AA), as the feed ingredients used to supply AA are often expensive. Furthermore, any AA supplied in excess is deaminated and the resulting nitrogen excreted, thus posing a potential environmental problem. Beca...
