Gums from high and low glucosinolate rapeseed oils were mixed at 1, 2 and 4% levels into Tower rapeseed meal (RSM; low glucosinolate cultivar) and soybean meal (SBM). These meals were fed in grower diets at 15.1 and 12.6% levels, respectively, to 72 pigs from 23 kg initial to 91 kg final weight. Neither the source nor level of gums had any effect on rate of growth or feed consumption. The digestibility of energy was determined by feeding Tower gums at 0, 1.25, 2.50, 5.00 and 10.00% of diets containing 15% of gums-free Tower RSM. Gums had no apparent effect on energy digestibility. All diets were 80% (79.6 ± 0.5) digestible, regardless of dietary level of gums, indicating that gums were similarly well digested. Samples of RSM and SBM containing 8% gums were kept in burlap containers at ambient temperatures over a 7-mo period to determine storage effects. No significant deterioration occurred as indicated by acid values, color or anisidine values. There were some differences in values between RSM and SBM but probably not of nutritional importance.

Potato steam peel (SP) is a by-product of potato processing where the peel is removed after steaming. It typically contains 15 ± 3% dry matter, 16 ± 1% crude protein, 0.55 ±.05% lysine, 0% methionine/cystine and 6% ash (dry matter basis). Steaming effectively deactivates the proteolytic enzyme inhibitors and partially denatures the starch. SP was evaluated in a digestibility trial and at levels from 0 to 30% DM in two feeding trials. The digestibility (%) of SP by pigs was found to be 88.4 (DM), 80.1 (CP) and 86.1 (DE). In the first feeding trial diets containing levels of 0, 10, 15, 20, 25 and 30% SP supplemented with methionine resulted in similar growth performance and carcass characteristics. In the second feeding trial, a comparison was made between a constant level of inclusion and an increase in inclusion level with age. Results showed no difference in growth performance or feed consumption among treatments. It is concluded that SP can be incorporated in diets for growing-finishing pigs at levels up to 30% DM. No change in performance resulted from increasing level of inclusion with age. Key words: Potato, steam peel, pigs, digestibility

ABSTRACT: This study evaluated the effects of chromium yeast and digestible lysine levels on the performance and carcass characteristics of finishing pigs. Sixty-four barrows with an initial weight of 72.77 ± 7.20 kg and final weight of 119.44 ± 9.47 kg were used, distributed in a 2 x 2 factorial scheme, with two levels of chromium yeast (Cr0: 0 ppb and Cr800: 800 ppb) and two levels of digestible lysine (L0: recommended level and L+10%: 10%). The recorded air temperature of 30.9 ± 3.7 ºC during the experimental period was considered as heat stress. Performance variables were not influenced (P>0.05); however, L+10% showed an increase (P<0.05) in daily digestible lysine intake. Carcass characteristics of the animals were not influenced (P>0.05) by the chromium or digestible lysine levels. Supplementation with 800 ppb of yeast chromium and a 10% increase in the level of digestible lysine, isolated or associated, did not improve the performance and carcass characteristics of finishing pigs, subjected to high ambient temperatures.

Performance Trial

This study aimed to evaluate the use of silage of forage cactus (Opuntia ficus-indica Mill) in diets for finishing pigs. Two experiments were conducted: the first for digestibility and the second for performance. In the performance trial, the quantitative levels of feed restriction (0%, 10%, 20%, and 30%) were evaluated, which were associated with the supply of forage cactus silage. Forage cactus silage presented 2463.59 and 2456 kcal/kg of digestible and metabolizable energy, respectively. The feed restriction levels associated with the supply of forage cactus silage influenced feed intake, weight gain and final weight negatively, but did not affect feed conversion. Carcass absolute weight was influenced negatively. However, the yield of carcass and cuts and the amount of meat in the carcass were not influenced. With the increase in feed restriction, there was a decrease in duodenal mucosa thickness, intestinal glands, liver glycogen storage and the occurrence of inflammation in the submucosa and intestinal mucosa. Forage cactus silage is not accepted well by animals. The restriction up to 30% of balanced feed did not affect feed conversion, yield of carcass and cuts and economic viability. However, levels over 10% affected intestinal health.Keywords: Alternative feed, feed preservation, intestinal health, Opuntia ficus-indica Mill, pig nutrition

This report presents effects of low temperatures on the feed consumption and efficiency of milk production of six mature, lactating, Holstein-Friesian cows that were confined in stanchions for three fortnightly experimental periods during which ambient temperatures measured in degree-hours per day (d-h/day) ranged from 110 to 1152 and daily minimum ambient air temperature (DMAAT) varied from 0° to 38°F. Applying results obtained, it was calculated that as temperatures decreased, i.e., d-h/day increased from 100 to 1200 and DMAAT decreased from 40° to 0°F, average daily intakes of total dry matter, hay, and gross and digestible Calories increased approximately 6.4 lb., 5.3 lb., 13 Therms and 9 Therms, respectively. Each of these increases was statistically significant at the 1 per cent level. Reductions in temperature also decreased gross and net caloric efficiencies of milk production approximately 10 and 8.5 per cent, respectively. These decreases were significant at the 2 per cent level. No correlation was evident between crude protein utilization and temperature.Results indicated that thermal stress was not overcome adequately by supplementary hay intake alone and that appetite stimulation by low temperatures had a carry-over effect continuing at least 24 hours. For continued efficient milk production during winters where low ambient temperatures are prevalent these results suggest it is necessary to provide some form of building insulation, ambient heat and/or provide a high energy supplement to otherwise adequate production rations.

In experiment 1, 12 cows were used to compare the two (0–0) rapeseed meal (1788 and Tower) varieties with the commercial rapeseed meal (CRSM) and soybean meal (SBM). Feed intake, milk yield and fat content were not different (P > 0.05) among the four treatments; however, protein content was higher (P < 0.05) for the cows fed CRSM and SBM diets than for those fed the 1788–RSM diet. But more (P < 0.05) milk fat was produced by the cows fed 1788–RSM than by those fed CRSM and SBM diets. In experiment 2, eight cows were used to determine the effects of replacing SBM with Tower and also replacing a portion of Tower with urea (TU) in a mixed or extruded (TUE) form on feed intake, milk yield and nitrogen (N) retention. No differences were observed in feed consumption, milk yield or composition among the treatments. Serum thyroxine (T4) level was higher (P < 0.05) for the cows fed SBM than for those fed the 1788–SBM and was similar to levels for cows fed CRSM and Tower in the first experiment. However, no differences were found in thyroxine level in the second experiment. Extrusion of Tower–urea mixture increased (P < 0.05) the N retention compared with other treatments. These short-term studies suggest that up to 25% Tower RSM can be used in dairy rations without adverse effect on performance.

It is common practice for feed barley to be purchased on sample specific weight. It can be argued that this historic measurement may give a misleading indication of its energy and feeding value. If this were to be true, then 6-row barleys which have a number of agronomic advantages, including high yields, could be discriminated against when compared to the more common 2-row barleys. Manitou is such a 6-row barley, which has out-yielded the best performing 2-row varieties by 6% in England (NIAB Recommended List 1991), and by 28% in Scotland (Scotland Agricultural Colleges Recommended List 1991). Trials were undertaken to compare Manitou and Marinka (2-row barley) at similar thousand grain weights (TGW), but different specific weights (sp.wt), with growing and finishing pigs.

An experiment was conducted to determine the effects of feeding diets containing 0, 5, 10, and 15% ground raw rapeseed to three replicates of 14 laying hens each. Isocaloric isonitrogenous diets were fed for a 28-day experimental period and performance and egg quality parameters were measured. Egg production was depressed at the two higher levels of rapeseed inclusion but was not affected at the 5% level of inclusion. Haugh unit, albumen height, and shell deformation were not affected significantly (P > 0.05) but egg weight decreased progressively as rapeseed inclusion increased. Feed consumption was significantly depressed (P < 0.05) at the 15% level of rapeseed and slightly reduced at the other levels.
