For up to 26 days mature wethers were given a diet with 25% spent coffee grounds, a by-product of the instant-coffee industry. The coffee grounds had crude protein 10, crude fibre 44, ether extract 26, ash 0.75, moisture 8 and tannic acid 0.9%. The diet was mixed 50:50 (by weight) with water to over...

Fish meals (herring, menhaden, and anchovy), commercially available in Atlantic Canada and a Norwegian fish meal (Norse-LT94Reg.) formulated to contain 0, 16, 28 or 40% protein were evaluated for protein quality by in vitro assays and by growth studies with Atlantic salmon fingerlings. Pepsin digest...

Nine multiparous cows in early lactation were fed alfalfa silage ad libitum twice daily, a grain-based concentrate five times daily, and one of three protein sources five times daily. Supplemental proteins were soya-bean meal, raw coarse-ground sweet white lupins or roasted coarse-ground sweet white...

Two feeding trials were conducted to evaluate lupin seed (Lupinus albus) as a replacement for soyabean meal at levels of 0, 5, 10, 15, 20 and 25% of starter diets fed to 192 pigs, from 10 to 20 kg liveweight. ADF and NDF concentrations in the diets increased as the proportion of lupin in the diet in...

The N degradability and N digestibility of raw, roasted or extruded oilseeds were studied using an in vitro enzyme method. The N degradability and N digestibility of canola, linseed and soybean were calculated based on the proportional difference in N remaining after incubation and the initial N con...

Fresh excreta from caged laying hens were treated with 3% tannic acid or 2% paraformaldehyde. Two diets were made up with 64% wet weight of the excreta, 28% lucerne hay and a little maize, molasses and supplements. The diets had gross energy (GE) 3.9 to 4.0 kcal/g. A control diet had moistened soya ...

Droppings were collected every 2 days from hens on a standard maize and soya bean oilmeal diet with 17% protein. In DM crude protein was 27.5, Ca 8.5 and P 2.3%. The untreated excreta with 70% moisture was included as 30% in a diet at the expense of maize and oat husks to give a diet with 15% crude ...

In a randomized block design nutritional quality of 2 new varieties of full-fat soyabeans (SB) in broiler starter diets was evaluated. Protein sources were raw SB (39% crude protein (CP), 70 Trypsin Inhibitor Units (TIU) per g DM), autoclaved SB, autoclaved high protein (HP) SB, low trypsin inhibito...

The effects were examined of replacing part or all of the soyabean meal in the starter and finisher diets for male broiler chickens with ground, roasted, full-fat soyabeans from either a high-protein (AC Proteus) or conventional (Baron) cultivar. The starter (1-21 days) and finisher (22-36 days) die...

The effect of body fatness on glucose metabolism was studied in 6 adult crossbred wethers, weight 90 kg (fat) or 55 kg (thin). Glucose turnover measurements were made using [6-superscript 3H]glucose by single injection at metabolizable energy (ME) intakes:high, 17 MJ/day; intermediate, 10 MJ/day; lo...

Blood glucose, free fatty acids, insulin, thyroxine and free thyroxine were measured in fat (weight 90 kg) and thin (55 kg) adult sheep at 4 levels of feed intake. There were differences between groups in blood metabolites and hormones and the possibility of insulin resistance occurring in fat rumin...

A new type of soyabean, AC Proteus, containing higher protein than conventional cultivars was evaluated using Landrace x Hampshire pigs, weighing about 10 kg. In the first trial, AC Proteus was included at 0, 4, 8, 12, 16 or 20% of the isonitrogenous and isoenergetic soyabean meal-based diets and fe...

The lipoprotein and lipid composition of the serum in postabsorptive haddock was characterized. A low level of very low density lipoproteins (VLDL; <50 mg/dl) was observed in serum. High density lipoprotein (HDL) was the predominant lipoprotein class followed by low density lipoproteins (LDL). Of...

20 Holstein cows in midlactation were used in a Latin-square design to evaluate the nutritional quality of a high-protein soyabean (CP 45%) given raw or roasted. Treatments were: (1) control (soyabean meal); (2) conventional soyabean (Maple Isle), raw; (3) conventional soyabean, roasted; (4) high-pr...

The effects of overfeeding by gastric intubation on body composition and energy metabolism of adult female rats were studied. There were significant linear increases in carcass DM, fat and energy during 10 days as daily metabolizable energy (ME) intake was increased from 160 to 300 kJ. Rats were giv...

Dimethylacetamide (DMA) was compared with DMSO as a cryoprotectant for rainbow trout (Oncorhynchus mykiss) spermatozoa on the basis of motility, percentage of dead spermatozoa, enzyme leakage and fertility of thawed spermatozoa. DMA performed better (P<0.05) than DMSO for all traits..

In the first experiment adult rats were allowed access to different amounts of diet of high energy density and were allowed to grow until there was a spread of bodyweights of 100 g. Of this difference 50% was fat and 10% was protein. Intakes were then adjusted to maintain a constant bodyweight and e...
