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

Daily Gain

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.

White Leghorn pullets were offered a corn, soybean meal laying diet or similar diets containing 15% canola meal. These diets were fed with dietary calcium levels of 3 and 5% and two levels of supplemental phytic acid (0 and 0.2%). A significant decrease in feed intake was noted with the canola meal diets. Poorer shell quality was noted for the canola versus the soybean meal diets, the low vs. high calcium diets and the phytic acid supplemented vs. nonphytic acid supplemented diet.

Sodium Supplementation

Two experiments were conducted to study the available sodium and potassium in canola- and soybean-meal-based diets containing no supplemental salt. A response in weight gain and feed: gain ratio was noted when potassium was added to soybean meal basal diets, but not when added to a 20% canola meal diet. This response depended upon the level of sodium supplementation. Supplementation of a soybean meal diet with up to 0.08% sodium resulted in improved performance of broiler chicks; however, only 0.06% sodium supplementation was required with a 20% canola meal diet to obtain a similar response. Calculations suggest that the availability of sodium in soybean meal is less than that found in Canola meal. Key words: canola meal, sodium and potassium

A completely randomized design (CRD) was used with a total of 160 day-old commercial broiler chicks which were randomly assigned to four treatment groups with five replicates into 20 pens and brooded. Feed and water were provided ad libitum. From day old chick to 21 day, the broiler chicks were fed Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (3% fish meal and 30% soybean meal, 1: 10) was served as control diet, Diet 3 (2% fish meal and 30% soybean meal, 1: 15) and Diet 4 (1.5% fish meal and 30% soybean meal, 1: 20). From day 22 onwards, the broiler chicks were fed finisher diet, Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (2.6% fish meal and 26% soybean meal, 1: 10, serve as control diet, Diet 3 (1.8% fish meal and 27% soybean meal, 1: 15) and Diet 4 (1.3% fish meal and 26% soybean meal, 1: 20). Weekly performances and mortality are measured. By feeding FS5 diet (5% fish meal and 25% soybean meal), the heavier body weight, increased feed consumption and feed conversion ratio of broiler chicks was observed when compared to that of other treatment groups. Conclusively, it is obvious that the ratio of dietary fish meal to soybean meal 1: 5 (FS5) improved body weight but the lower feed efficiency of this diet should be considered in economical point of view.

SUMMARYFour Holstein steers (297 ± 56 kg of body weight (BW)) fitted with duodenal cannula and rumen catheter, were housed in metabolism cages and used in a 4 × 4 Latin Square trial to evaluate the effect of both protein source andAcacia mearnsiitannin extract on digestibility, ruminal fermentation, rumen microbial protein synthesis, N utilization and on duodenal flow of individual amino acids. The diet was offered at restricted amount of 25 g of dry matter (DM)/kg BW and consisted of maize silage plus concentrate, in a proportion of 0·7:0·3 (DM basis) respectively. Concentrate was formulated with either soybean meal or canola meal as protein source, with or without 50 g/kg ofA. mearnsiitannin extract (i.e. 15 g/kg of total dietary DM). There was no effect of protein source on most variables. The apparent and true organic matter (OM) digestibilities, as well as neutral detergent fibre (NDF) digestibility were negatively affected by tannin extract inclusion without, however, affecting digestible OM intake. The amount of nitrogen (N) excreted in faeces increased whereas the urinary N excretion decreased in tannin extract treatments. No interaction time × treatment was detected for any rumen variable and no treatment effect was observed for rumen fluid pH and reducing sugars concentration. Rumen fluid concentration of ammonia N was lower for the canola meal plus tannin extract treatment. Rumen concentration ofα-amino compounds was not affected by tannin extract but was higher when canola meal was the protein source. The duodenal flow of OM, total N,α-amino N and non-ammonia non-microbial N increased with tannin extract inclusion, whereas the duodenal flow of microbial N was not affected by treatment. For both protein sources, the amount of most individual amino acids flowing to the duodenum increased due to tannin extract addition. In conclusion, the dietary inclusion of 15 g/kg DM of tannin extract fromA. mearnsiiimproved the amino acid supply independently of whether the protein source was canola meal or soybean meal, without affecting the amino acid profile, to steers fed maize silage plus concentrate, with a minor but significant impact on OM digestibility.

Three experiments involving 11 600 male broiler chickens sought to determine if the pelleting process affects the dietary micronutrient, fat and protein components to increase the incidence of sudden death syndrome. Processed dietary micronutrient and fat components were not significantly associated with an increase in sudden death syndrome among broiler chickens. In one of the experiments, the incidence of sudden death syndrome was reduced (P < 0.01) when the dietary protein supplements (soybean meal, canola meal and fishmeal) bypassed the pelleting process.

Metabolizable Protein

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

Ad Libitum

Two very low glucosinolate (VLG) canola meals from crop years 1987 and 1988 (CM; 1.66 and 0.53 μmol g−1) and two Tobin CM (B. campestris) (10.71 and 15.62 μmol g−1) were evaluated in experiments with pigs. In exp. 1, 1987 Tobin CM, VLG-CM and soybean meal (SBM) were compared in individually fed meal and pelleted diets. Daily gains from 23 to 57 kg were similar for the CMs (VLG-CM 662 g, Tobin CM 645 g) but lower than those obtained with SBM (730 g; P < 0.01). Daily feed intakes of pigs fed CM were lower than for those fed SBM (P < 0.05). Plasma thyroxine (T4) levels were similar for SBM and VLG-CM and were above those from pigs fed Tobin (P < 0.05) CM. Triiodothyronine (T3) levels were lower for VLG-CM than for SBM (P < 0.05) and the T3 value for Tobin CM was intermediate. Pelleting enhanced T3 (0.70 vs 0.94 ng mL−1) and T4 (50 vs. 60 ng mL−1) levels with all protein supplements (P < 0.01). In exp. 2, similar diets were fed ad libitum. Daily gains for SBM were greater than for Tobin CM (803 vs. 744, P < 0.05) and gains for pigs fed VLG-CM was 774 g. Daily feed intakes were similar (2.01, 1.99 and 1.92 kg). In exp. 3 energy digestibility of 1987 VLG-CM was greater (P < 0.01) than for Tobin CM (75.0 vs 67.4% for 30-kg pigs). Apparent digestibility coefficients of crude protein (CP) were 71.9, 71.2 and 71.6 in 16% CP diets. In exp. 4 Tobin and VLG-CMs from 1987 and 1988 crops were compared with SBM and commercial CM using 96 pigs (48M, 48F). Daily gains and feed intakes were similar for the CMs but T3 and T4 values were below those of SBM (P < 0.05). Key words: Canola meal, very low glucosinolate, digestibility, feeding value, pigs

Growing Period

One hundred ninety-two male broiler chicks were dosed with monensin at concentrations of 0, 121, or 242 mg/kg feed throughout the normal growing period (50 days). Body weight gain and feed efficiency were determined weekly, and cardiac muscle was examined grossly and histologically at the end of the experiment. Livers also were weighed and examined grossly. Feed intake was determined daily, allowing continuous monitoring of drug intake. No depressing effects of the drug on growth rate and efficiency were observed until after four weeks, and then were evident only in the chicks receiving the 242 mg/kg diet. Subepicardial hemorrhage and congestion occurred in 40% of the hearts from the chickens fed the high monensin dose and were nonexistent in the other treatments. There appeared to be an inverse relationship between monensin dose and liver weight. The paralytic effects previously reported from acute dosing experiments were not observed. The results show that the heart and probably the liver are sensitive indicators of monensin toxicity and that the subchronic toxic dose is less than 18 mg/kg body weight per day.
