An alfalfa silage-corn silage diet (15% concentrate) was similar in chemical composition to a hay-haylage-alfalfa silage-corn silage diet (25% concentrate). When fed to dairy heifers (238–350 d of age), the two diets resulted in very similar rates of gain (969 vs. 950 g d−1), heart girth and withers height. Heifers of both of these groups experienced considerable breeding problems. In a silage diet, grain content and its cost may be further reduced to obtain the desired rate of gain of about 700 g d−1 for dairy heifers growing from 200 to 300 kg body weight. Key words: Silage diet, growth rate, dairy heifers

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.

A set of four sheep, each fitted with a rumen cannula and a re-entrant cannula in the ascending duodenum and terminal ileum, were used for collection of rumen, duodenal and ileal digesta. A second set of four normal sheep was used for collection of feces and urine. The sheep were fed corn silage, urea-added corn silage, formic acid-treated alfalfa silage or wilted alfalfa silage in latin square design. Soluble proportions of manganese in rumen fluid, ileal digesta and feces were much lower on alfalfa silages than on corn silages although the soluble proportions in the duodenal digesta were not different. The soluble proportions of zinc, copper and iron were not as consistent as those of manganese. The apparent absorption of zinc was negative on alfalfa silages, and was associated with the lower soluble proportion of zinc in duodenal digesta and higher in the ileal digesta, as compared to corn silages. The apparent absorption of iron was much higher on corn silages than on alfalfa silages. Addition of urea to corn at ensiling resulted in an improvement of apparent absorption of copper.

<p>A triplicate experiment was conducted to evaluate the addition of probiotic <em>Bacillus </em>sp. into the diet on feed convertion and growth of catfish <em>Pangasius hypophthalmus. </em>Twenty fish with an initial body weight of 1,85 <em>± </em>0,09 g were stocked in a 60-1 aquarium. During rearing period, fish were fed on the diet three times a day at satiation. Prior the feeding, probiotic (contained <em>Bacillus </em>sp. 4,2x106 CFU.ml-1) were added into the diet at a dosage of 0, 5, 15 or 25 ml.kg-1 diet. The probiotic were added once a day at the noon. The results showed that maximum protein retention, lipid retention, growth rate, and minimum feed convertion was found in the group of fish fed on the diet supplemented with 15 ml probiotic kg-1 diet. Irrespective to the dosage of probiotic, food consumption and survival rate of fish were the same among the treatments.</p> <p>Key words : Probiotic. <em>Bacillus </em>sp.. catfish <em>Pangasius hypophthalmus. </em></p> <p> </p> <p>ABSTRAK</p> <p>Penelitian ini bertujuan untuk mengetahui dosis yang optimal dari probiotik <em>Bacillus </em>sp. yang ditambahkan pada pakan komersil terhadap konversi pakan dan pertumbuhan benih ikan patin <em>Pangasius hypophthalmus. </em>Dua puluh ekor ikan patin dengan bobot rata-rata 1.85 ± 0,09 g ditebar dalam setiap akuarium frekuensi 50x40x35 cm yang diisi air 60 1.

In a 110-d grazing study, 75 yearling steers were left unimplanted or implanted at Day 0 with 24 mg 17β-estradiol, 36 mg zearanol, 72 mg zearanol, or 36 mg zearanol at Day 0 and 84. Within each implant group, steers were also supplemented with barley (0.5 kg head−1 d−1) with or without lasalocid (0.75 mg kg body weight−1 d−1) or were given no supplement in a 5 × 3 factorial design. Average daily gain (ADG) for all implanted steers was 17.5% greater (0.94 vs. 0.80 kg d−1) than for unimplanted steers (P < 0.01). Increasing the dosage of zearanol from 36 to 72 mg extended the time over which ADG was increased but total liveweight gain and ADG over the 110-d grazing season were similar for all implant types. A second implant of zearanol (2 × 36 mg) increased ADG during the final 26 d of the pasture phase and during the drylot period, compared with 72 mg zearanol given initially. Barley + lasalocid-supplemented steers had ADG 17.3% greater (1.02 vs. 0.87 kg d−1) than barley-supplemented steers (P < 0.01). During the following drylot phase, when no lasalocid was fed, ADG was lower (P < 0.10) for steers that had previously received lasalocid than for other groups. No interactions were observed between implant and supplement type. Thus, the anabolic implants and ionophores used in this study are additive in improving growth rate. Key words: Cattle, feedlot, grazing, lasalocid, zearanol, 17β-estradiol, growth

The growth of pastured calves, as affected by supplementary grain feeding, moderate and high prepasture planes of nutrition, and age on going to pasture (56, 112, or 168 days), was compared with growth of calves on a standard barn feeding regime. Seventy-two Holstein heifer calves were involved with treatment comparisons based on gains in body weight, withers height, heart girth, and barrel circumference.Over-all gains of pastured calves were not affected by either prepasture plane of nutrition or age to pasture and were similar to gains of barn-fed controls. Calves fed supplemental grain (crushed oats) showed no increase m growth rate. This was attributed to a lower intake of forage by the supplemented animals and the relatively high quality of the forage as indicated by chemical composition and digestibility.Seasonal growth patterns of pastured calves showed a depression during the initial period on pasture. However, this was overcome by greater gains than barn-fed controls during the later pasture periods.

ABSTRACTIntact male lambs from Limousin and Charmoise breeds, or crossbreds from F1 (Romanov × Limousin) ewes sired by Berrichon rams, were early weaned, intensively fed, and slaughtered between 20 and 40 kg of empty body weight. The whole carcass was chemically analyzed, and the results expressed on a shorn, empty body-weight basis.Some between breed differences in the weight of fat and gross energy content were found: fat contents ranged from 179 to 212g/kg at 30 kg of empty body weight. The corresponding range for energy was 10·8 to 11·8MJ/kg of empty body weight. Differences between protein and ash contents were limited, from 154 to 165g/kg empty body weight, and from 31 to 33g/kg empty body weight respectively.At the same empty body weight Charmois lambs (a small sized breed) contained more fat, less water and less protein than the crossbreds. Values obtained on the Limousin lambs were intermediate.There was no evidence of diet or growth rate effect on chemical composition when compared with published data obtained from more conventionally fed lambs.

Forty crossbred beef steers were used in a 112-d experiment to study the effect of fish meal (FM, 300 g d−1), soybean meal (SBM, 320 g d−1), barley (B, 2 kg d−1) and B plus FM (2 kg + 300 g d−1) supplementation of grass silage on the performance of growing cattle. The growth rate of steers fed silage was 0.83 kg d−1 and this was increased by 0.15, 0.12, 0.27 and 0.36 kg d−1 by supplements of FM, SBM, B and B + FM. Silage dry matter (DM) intake averaged 2.13% of body weight. Protein supplementation had no effect on silage intake. B and B + FM supplementation increased total DM intake (P < 0.01), but decreased silage consumption by 14% (P < 0.05). Key words: Cattle, grass silage, soybean meal, barley, growth, fish meal

This study was conducted to elucidate the interaction effects of temperature and dietary lipid levels (2 × 2 factorial experiment) on the growth performance, muscle, and liver composition in adult farmed European sea bass (Dicentrarchus labrax). Two groups of fish (190 g; 60 fish per group) were distributed in 12 tanks in triplicates and kept at two different temperature regimes; one starting at 23 °C and then changed to 17 °C for 61 days, and the other starting at 17 °C and then changed to 23 °C for 39 days. Two commercial diets containing both ~44% crude protein but incorporating different dietary lipid levels, 16.5% (D16) and 20.0% (D20) (dry matter (DM)), were fed to the fish to apparent satiation; the type of diet fed to each fish group remained constant throughout the experiment. Final body weight, weight gain, and specific growth rate were significantly higher for the fish group held at 23 °C compared to the fish group at 17 °C (before the temperature changes), while the dietary fat content did not have any profound effect in both groups. Furthermore, the different temperature regimes did not affect muscle or liver composition, but, on the contrary, dietary lipids affected hepatosomatic, perivisceral fat, and visceral indexes. Feed conversion ratio and specific growth rate were not affected by the dietary lipid level. An interaction of temperature and dietary lipid content was observed in daily feed consumption (DFC) and final body weight (FBW).
