This experiment evaluated the suitability of dried seal meal (SM) as a protein supplement for growing steers. Protein in the SM had an effective degradability of 65% and a slow degradation rate in the rumen. There was a positive quadratic growth response to replacing soybean meal (SBM) with SM (P < 0.05). We attribute this response to optimized concentrations of fat and metabolizable protein supplied by the SM/SBM mixtures. We conclude that SM is a beneficial protein source for growing steers when combined with SBM. Key words: Growing steer, seal, protein supplement, silage

Ninety-six Large White pigs were used in four experiments to compare supplements of decorticated safflower meal with soybean meal in either sorghum or wheat based 'grower-finisher' diets. Synthetic lysine, fishmeal and combinations of safflower meal-fishmeal and safflower meal-fishmeal-synthetic lysine were tested as supplements. Decorticated safflower meal was found to be unsatisfactory as the sole supplementary protein source for sorghum and wheat based diets for pigs. The growth response to the safflower meal was increased by the addition of synthetic lysine but the performance of pigs receiving these lysine enriched safflower meal supplements was always inferior to those fed either isonitrogenous soybean meal or fishmeal supplements in both sorghum and wheat based diets. Increasing safflower protein contribution in the safflower mealfishmeal diets resulted in poorer feed conversion ratios and growth rates, particularly when fed to pigs less than 45 kg live weight. The results showed that if safflower meal was to be used in pig diets, it should be used in conjunction with 'lysine rich' protein concentrates and restricted to pigs exceeding 45 kg liveweight.

Initial Weight

First- and second-litter progeny from sows fed either 0 or 8% solvent-extracted rapeseed meal in replacement for isonitrogenous amounts of soybean meal and wheat was used to evaluate solvent-extracted rapeseed meal as a protein source. There was no influence of the dam’s diet on gain, efficiency of feed utilization, digestible (DE) and metabolizable energy (ME) or digestible nitrogen (DN) and nitrogen retention in the progeny. In pigs from first litters, the feeding of 8% rapeseed meal, compared with 0% rapeseed meal, depressed feed intake and rate of gain in the finishing period from 55 to 90 kg liveweight, and resulted in reduced gain and poorer efficiency of feed utilization for the overall experiment from 6 kg initial weight. Carcasses from rapeseed meal-fed pigs were leaner. Gilt carcasses were leaner than barrow carcasses. With second-litter pigs, there were no significant differences associated with dietary treatment or sex. There were no significant differences in DE or ME or in DN and nitrogen retention between pigs receiving 0 or 8% rapeseed meal in either the starting diets at 6 weeks of age or the growing diets at 40 kg liveweight.

Alfalfa Silage

Sixty-six Hereford steers were fed rations of corn silage, or corn silage plus 400 g∙head−1∙day−1 of soybean meal, or a mixture of corn and alfalfa silage (ratio 1:1 on a wet basis at ensiling). Alfalfa, when mixed with forage corn at ensiling, can be used as a protein supplement to replace a part of the soybean meal but corn silage alone may not be recommended.

Similar Growth

Three groups, each of five pigs, of initial age 5–6 weeks and initial weight 12 kg, were placed on each of three wheat-soybean-meal-based diets of 18% crude protein content. The diets contained either (a) no antibiotic, (b) 110 mg/kg chlortetracycline hydrochloride, 110 mg/kg sulfamethazine and 55 mg/kg penicillin, or (c) diet (b) minus penicillin. Both antibiotic treatments produced a similar growth response of approximately 12%, which resulted partly from an increased feed intake and partly from an improved efficiency of feed utilization.

Tower rapeseed meal was substituted on an isonitrogenous basis for 50, 75 and 100% of the soybean meal in diets for weanling rabbits. There was no significant effect (P < 0.01) on average daily gain or feed efficiency, indicating that Tower rapeseed meal is equivalent to soybean meal as a protein supplement for growing rabbits.

Two experiments were conducted to investigate the nutritive value of sausage casings prepared from cattle hides as a protein source for day-old hybrid (Hubbard × Hubbard) broiler chickens. The results demonstrate that sausage casings are an available protein source for broiler chicks that can be substituted for soybean meal at levels up to 8% of the feed without affecting average daily gain and feed efficiency.

Inorganic Sulphur

Several studies were undertaken to investigate the interaction of calcium and sulphur when added to semi-purified diets containing either canola or soybean meal, as the only protein source. High levels of sulphur supplementation reduced the performance of birds fed diets containing both sources of protein; however, it was more severe with canola than with soybean meal diets. Sulphur coming from methionine resulted in poorer bird performance than that coming from cystine. Increasing dietary calcium levels from low to close to the requirement level partially alleviated the detrimental effects of the higher sulphur supplementation. Liver weight was not altered, as a percent of body weight, at the high sulphur levels, suggesting little or no liver involvement in the reduced performance noted. Reduced performance often reported for birds fed canola versus soybean meal diets may well be due, in part, to the higher level of sulphur in canola meal than soybean meal, in particular the inorganic sulphur fraction. However, the present study utilized diets containing 40% canola meal, which is much higher than would be found in practical type diets. Thus care must be taken in extrapolating the present findings to practical conditions. Key words: Chickens, canola, calcium, sulphur, methionine
