The effects of dietary lipid levels on growth, feed utilization, hepatosomatic index (HSI), liver lipid deposition and tissue fatty acid composition in haddock were investigated. Triplicate tanks of juvenile haddock (6.9 g) were fed graded levels of herring oil to supply 14, 16, 19 and 22% lipid (DM...

Lupins were roasted in a flame roaster with an exit temperature of 105 degrees C. The effect of heating on protein solubility and rumen degradability of lupin were evaluated by chemical and Dacron bag procedures. Solubility of nitrogen in buffer was reduced from 69.8% in raw lupin to 35.8% in roaste...

Sweet white lupins (Lupinus albus) and a high protein variety of soyabeans, AC Proteus (HPSB), were roasted in an electric roaster at 300 degrees C for 1, 2, 3 or 4 min. Raw and roasted samples were analysed for total nitrogen, acid detergent insoluble N and protease insoluble N, and available rumen...

80 ejaculates were obtained from each of 4 [male][male] from a line selected for post-thawing fertility duration of their inseminated spermatozoa, and the same number of ejaculates was obtained from 4 [male][male] of a randombred line. Semen was diluted with N,N-dimethylacetamide (DMA) or glycerol a...

Effects of processing whole soyabean on growth characteristics, fatty acid composition and lipid peroxidation activity of beef tissue were investigated with 40 crossbred steers. The basal diet consisted of grass and corn silage, barley grain, vitamins and minerals. The dietary treatments were: raw s...

Twenty-eight Simmental-cross steers weighing 200 (+/- 20.5) kg were used to evaluate grass and whole plant lupin silages in terms of growth rate, dry matter (DM) intake and carcass characteristics. The chemical composition of the silages was determined and Dacron bag procedures were used to estimate...

In Experiment 1, 24 multiparous cows in early lactation were given a basal diet for ad lib. intake consisting of 24.3% (DM) maize silage, 25.9% whole crop barley silage, 33.1% lucerne silage and 16.7% of a protein supplement. Raw barley grain, or barley flame roasted to reduce its rate of rumen degr...

For 3 weeks, 128 male Sprague-Dawley rats, 3 weeks old, were fed on diets containing no protein, casein, soyabean meal, roasted or raw soyabeans, or sweet white lupin (Lupinus albus) cultivar Primorski or Ultra without or with 0.1% lysine or 0.2% methionine. Relative net protein ratio (RNPR) (casein...

The effect of body fatness on the fasting heat production and energetic efficiency of adult sheep was studied. Energy balance and heat production were estimated in adult wether sheep at 3 fatness levels given a diet of grass hay and maize at 4 feeding levels, including fasting, in open-circuit respi...

Amino acid availability values for Atlantic salmon were evaluated for two steam- and one flame-dried herring meal, menhaden meal, anchovy meal, and a Norwegian capelin meal (Norse-LT94(R)). Apparent amino acid availabilities were calculated based on feces collected either by manual stripping or sedi...

A low trypsin inhibitor soyabean (LTI) was characterized using electrophoresis, enzyme activity measurements and gel exclusion chromatography. The protein profiles were similar to a control soyabean. Gel exclusion chromatography resulted in two peaks of trypsin inhibitor activity in the control. The...

Three cannulated, lactating cows were used in a 3 x 3 Latin square design to determine the effect of roasting or NaOH treatment of barley on ruminal fermentation and site and extent of digestion of nutrients. Experimental treatments were rolled barley, roasted (exit temperature, 135 degrees C) and r...

130-day-old [male][male] of the Quebec line were subjected to 6 lighting treatments from 5 wk of age. The percentage of [male][male] producing semen was significantly affected by light regime. Under 12-h light; 12-h darkness (12L:12D) with constant intensity (10.8 lux) or increasing intensity (5.4-5...

A three-step in vitro procedure was developed by Calsamiglia and Stern [J. Anim. Sci. 73 (1995) 1459] to estimate intestinal protein digestion after 16 h incubation in the rumen. The objective of our work was to modify this procedure to give an accurate estimation of N digestibility without the use ...

Haddock (Melanogrammus aeglefinus) is a gadoid fish species that deposits dietary lipid mainly in the liver. The fatty acid (FA) beta-oxidation activity of various tissues was evaluated in juvenile haddock fed graded levels of lipid. The catabolism of a radiolabelled FA, [1-(14)C]palmitoyl-CoA, thro...

120 pigs, 11.6 kg, were fed on barley-based diets in which 0, 25, 50, 75 or 100% of supplementary soyabean meal protein was replaced by dehydrated lupin seed (Lupinus albus cultivar Ultra). Starter pigs (10-20 kg) given the 25% lupin diet (25% L) had similar growth rates and consumed more feed (P<...

In 1996 at AquaBounty Farms (Prince Edward Island, Canada) the rates of routine oxygen consumption of 660 growth-enhanced transgenic Atlantic salmon (carrying a chinook salmon growth hormone gene driven by an ocean pout antifreeze gene promoter) were compared with that of 660 non-transgenic salmon, ...

In two experiments with 57 rats, the maintenance energy requirement (MER) of adult rats with different degrees of body fatness was proportional to metabolic body size and the combined equation was MER (kJ/day) = 394.8 Wkg0.75. Results indicated that the gains in protein and fat were nonlinear, the r...

Triplicate groups of Atlantic salmon (Salmo salar) fingerlings, about 4.7+or-0.2 g, were fed to appetite on diets containing 1.24, 1.76, 1.90, 2.19, 2.45, 2.68 and 2.94% lysine and gross energy 24.1 MJ/kg of diet (DM basis, DMB) for 70 days. The salmon were reared in water salinity 10 ppt at 15 degr...

15 multiparous Holstein cows in mid to late lactation were fed on lucerne silage and a concentrate diet (barley 747, maize 200 and molasses 30 kg/t) supplemented with soyabean meal (control) or raw or roasted lupin seeds in a Latin square arrangement consisting of three 4-week periods. Chemical comp...

The influence of food deprivation on the rate of oxygen consumption and the rate of mobilization/utilization of energy reserves in F2 generation growth-enhanced transgenic Atlantic salmon were compared relative to their non-transgenic counterparts, over a pre-smolt weight interval of 8 to 55 g. Thro...

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...
