Kochia (Kochia scoparia (L.) Schrad.) was grown on land irrigated with packinghouse wastewater and ensiled in a plastic silo bag. Kochia dry matter (DM) yield and acid-detergent fiber (ADF), Na, Mg, Mn, and Cu contents (DM basis) were correlated with some soil measurements. Alfalfa silage was replaced with kochia silage in a basal diet at levels of one-half (35% of diet DM) or all (70% of diet DM) of the roughage. The diets were fed to 120 calves (initial weight 294 kg) for 70 d in a completely randomized experiment with three treatments (kochia, kochia and alfalfa, and alfalfa) and four pen replicates. Inclusion of either 35 or 70% kochia silage in the diet DM depressed (P < 0.01) DM intake (DMI) by 23.3 and 50.1%, respectively, compared with calves fed the basal diet. Average daily gain (ADG) and final bodyweight of the calves fed kochia silage were both less (P < 0.01) than those fed the basal diet. DM conversion to liveweight gain ratios (DM: G) were 13.91, 8.42, and 7.15 when the diets contained (DM basis) 70, 35, or 0% kochia silage, respectively. Over the 42-d period following the trial, the calves that had received kochia silage tended (P = 0.078) to gain faster than those that had been fed the basal diet. The reduction in DMI observed when kochia silage was fed appeared to be the result of advanced maturity and weather damage of the kochia and not due to apparent toxic effects.

Daily Gain

Thirty-two large-frame crossbred steers (443 ± 5 kg) were used to determine the nutritive value of cracked corn, rolled barley, rolled oats and rolled wheat in finishing diets for beef cattle fed medium-quality grass hay. Diets contained about 54% grains, 40% grass hay and 6% of a supplement of minerals, vitamins and lasalocid. Total daily dry matter (DM) intake ranged from 9.52 to 10.24 kg, average daily gain from 1.09 to 1.17 kg and gain to feed ratio from 0.113 to 0.121, but these values were not statistically different (P > 0.05). Apparent digestibilities of DM and energy of steers receiving the oats diet were lower than those of steers receiving the wheat diet (P < 0.05), the other diets having intermediate values. Apparent digestion coefficient of protein was higher for the oats diet (P < 0.05) than for other diets. Acid detergent fiber digestibility was higher (P < 0.05) and starch digestibility was lower (P < 0.05) in steers receiving corn than in those receiving barley, oats or wheat. The results indicate that nutritive value of all diets was similar. Key words: Grains, fattening steers, digestibility

This experiment was conducted to evaluate the effects of corn or soybean hull incorporation into haylage-based diets on backgrounding calf performance and subsequent feedlot performance. Crossbred steers [n = 48, initial body weight (BW) = 303 ± 3.4 kg] were individually fed dietary treatments consisting of: (1) haylage [17.5% crude protein, dry matter (DM) basis; control], (2) haylage + 20% (DM basis) cracked corn, and (3) haylage + 20% (DM basis) soybean hulls during a 112-d backgrounding period. After the backgrounding period, all steers were adapted to a common high moisture corn-based finishing diet and fed until an ultrasound estimated backfat thickness of 7 mm was obtained. During the backgrounding period, steers fed cracked corn or soybean hulls had greater (P < 0.01) average daily gain, dry matter intake and gain:feed and lower (P = 0.05) plasma urea N as compared with controls. However, when finished on a common high-concentrate diet, steers previously fed cracked corn had greater (P < 0.08) average daily gain, final body weight, and longissimus muscle area than those fed soybean hulls, suggesting that source of supplemental energy during the backgrounding period may influence subsequent feedlot performance.

A study was conducted to examine how lupin grains (LUPs) feeding affected nutritional intake, digestibility, growth, and carcass characteristics in kids. A total of 24 growing black kids (initial body weight (BW) = 16.4 ± 0.49 kg) were allocated to one of three diets at random. Lupin was included in the diet at a rate of 0 (control; CON), 100 (LUP100), or 200 g/kg (LUP200) of total dry matter (DM). The trial lasted for 91 days divided into 7 and 84 days to be used for adaptation and data collection, respectively. Feed intake was evaluated daily throughout the study. At the commencement and the end of the study, each kid’s body weight was measured to determine its average daily gain (ADG). On day 70, 5 kids were chosen at random from each group to investigate nutrient in vivo digestibility and N balance. At the end of the study, all of the kids were slaughtered to examine carcass features. Nutrient intakes (neutral detergent fiber, acid detergent fiber, and ether extract) were higher (p ≤ 0.01) in LUP-containing diets than in the CON diet. The average daily gain was greater (p ≤ 0.03) in diets containing lupin grains than in the CON diet. Cost of gain ($US/kg growth) was lower (p = 0.004) in kids fed diets containing lupin than the CON diet. Dry matter and CP digestibility rates were greater (p ≤ 0.03) in lupin diets. Retained N was higher (p = 0.04) in lupin-containing diets than in the CON diet. Cold carcass weight was higher (p < 0.05) for kids consuming the LUP100 diet than the CON diet. In lupin diets, carcass cut weights were higher (p < 0.05). Results of the current study indicate that feeding black kids diets containing lupin grains at 100 or 200 g/kg DM basis is cost effective and would increase profitability.

The objective was to evaluate the effect of partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus on performance and body weight components of sheep. Thirty hair lambs, with 19 kg ± 0.35 kg initial weight, were randomly divided into five treatments, namely: Tifton 85 Hay (HA); Tifton 85 Hay + fresh spineless cactus (HAFC); Tifton 85 Hay + dehydrated spineless cactus (HADC); fresh spineless cactus (FC); dehydrated spineless cactus (DC). In addition to the spineless cactus and hay, the complete mixture contained soybean meal, mineral salt and limestone in all treatments. Animals were confined for 75 days and then slaughtered. The weight of body components was recorded. Dry matter intake, total digestible nutrients intake and voluntary water intake were higher (p < 0.05) for the DC and HADC treatments. The average daily gain was 118 g day-1 and body weight at slaughter of 25.8 kg were not influenced (p > 0.05) by treatments. The cold carcass weight, rib eye area, weight and yield of the skin, liver, kidney and large intestine were higher (p < 0.05) for the DC and HADC treatments. Partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus, in complete diets for sheep, increases the weight of the cold carcass and non-carcass components.

A total of 150 weaning pigs (7.53 ± 1.23 kg) were randomly assigned to three treatments consisting of basal diet, and the basal diet supplemented with 300 and 600 mg kg−1 of probiotics, respectively, in a 42 d trial. The incremental levels of probiotics linearly increased average daily gain during week 1 and through the overall experimental period (P < 0.05). The average daily feed intake, body weight, and the apparent total tract digestibility of dry matter, nitrogen, and gross energy also increased (P < 0.05) with the increased level of probiotics. A significant reduction in Escherichia coli counts (P = 0.0037) and increase (P = 0.0016) in Lactobacillus counts were observed on day 42.

Supplementing a control diet of ground alfalfa (CON) with monensin (MON), chlortetracycline (CTC) or tylosin (TYL) did not affect (P < 0.05) dry matter intake or average daily gain of market lambs. Feed efficiency with CTC was less than with the unsupplemented control (CON) (6.22 vs. 5.68) (P < 0.05). Mean digestibilities of dry matter, acid detergent fiber and neutral detergent fiber were lower (P < 0.05) with all antibiotic treatments than the CON diet. Relative to CON, nitrogen digestibility was increased with MON (66.3 vs. 70.9%) while that of energy was reduced with TYL (P < 0.05). Rumen ammonia and acetic, propionic and butyric acid concentrations were not influenced by any of the treatments. MON, CTC and TYL were not effective supplements for lambs fed alfalfa finishing diets. Key words: lamb, chlortetracycline, monensin, tylosin, alfalfa hay, digestibility

This meta-analysis evaluates the effects of yeast supplementation (Saccharomyces cerevisiae) on dry matter intake (DMI) and average daily gain (ADG) in beef cattle. The inclusion criteria were complete and randomized trials and supplementation with yeast S. cerevisiae versus no supplementation to measure DMI or ADG. Data were extracted from relevant papers via pre-defined protocols. A meta-analysis of random effects was conducted for each indicator separately including the mean of the control and treated groups. The results were presented with the pooled mean difference (MD), 95% of confidence interval, and I² (percentage of total variation between studies that is due to heterogeneity rather than chance). A total of 12 publications reporting 22 trials conducted in 1,161 cattle were analysed. The heterogeneity between studies was high and ranged from 92 to 99%. No effects were observed in ADG with the inclusion of yeast in the diet (MD = -2.849 g/day, p = 0.492). However, there was a reduction in the DMI (MD = -0.885 kg/day; p = 0.023) despite the high heterogeneity among studies (I2 = 92.4%; p < 0.001). The ADG increased when the forage level in the diet was between 30 and 50% (MD = 641.08 g/day; p = 0.001) and decreased when the level range from 51 to 75% (MD = -2.90 g/day; p < 0.001). In over 60% of the Neutral Detergent Fibre, the use of yeast in the diet decreased the ADG by 406.94 g/day (p = 0.034). Feedlot animals showed a reduction in the DMI (MD = -0.97 kg/day; p = 0.019) if supplemented with yeast. Supplementation with S. cerevisiae in the diet of beef cattle had no effect on ADG; however, it does improve the feed conversion due to the reduction in DMI.

The objective of this research was to determine the potential uses of dry matter in the average daily gain of beef cattle and rice straw carrying capacity as a feed alternative. The research used an analytical survey approach, and the location was chosen via purposive sampling. Data collection consisted of conducting interviews and observations based on a questionnaire; then, the collected data were tabulated and analyzed using descriptive statistics. Spearman’s correlation coefficient was used to determine the relationship between dry matter intake level and average daily gain; simple linear regression analysis was used to measure the effect of dry matter intake level on average daily gain. The results revealed that the average daily gain of beef cattle in North Samarinda, Palaran, Sambutan, and Samarinda Ulu (Indonesia) was 0.44 kg, 0.45 kg, 0.45 kg, and 0.45 kg, respectively. The analysis results of dry matter intake level on average daily gain obtained via the regression equation (Y) were as follows: Ỷ = 0.013 + 0.945X. This indicates that every intake of 0.945 kg of dry matter would yield an average daily gain increase of 0.013 kg. Effective utilization of available abundant feed resources (rice straw) is the key to economic maintenance of cattle; however, it tends to have low nutrition and low digestibility, so it is not given as a single feed because it cannot meet beef cattle’s dietary needs. This research found that rice straw production (each hectare of rice area) was able to supply alternative feed for beef cattle of 2.7 animal units per year.

The objective of this study was to evaluate the performance of beef heifers on Stapf. cv. Marandu grass pastures that were managed at three herbage allowances under continuous grazing with a variable stocking rate and were provided with mineral mix supplement or supplements with energy and protein. Seventy-two test heifers and 48 put-and-take heifers were used in a randomised design in a 3 × 2 factorial arrangement [three herbage allowances (1.5, 2.0, and 2.5 kg of green dry matter/kg of bodyweight, and two supplementation levels (mineral mix or 0.3% bodyweight of a mineral–protein–energy supplement)], with two replicates per treatment (paddocks), to maintain the pre-established forage allowance. No significant difference was observed in the gain per hectare as a function of the herbage allowance, but 2.5 kg green dry matter/kg bodyweight provided the greatest average daily gain of bodyweight (0.605 kg/animal/day). The energy/protein supplementation provided the greatest average daily gain compared with animals fed only the mineral mix. The supplements in the diet of beef heifers fed at 0.3% of bodyweight increased bodyweight gains without compromising the gain per hectare at different herbage allowances.

Corn for silage was planted at two seeding rates (60 000 and 200 000 kernels ha−1) in three consecutive years and evaluated by determining yields, digestibility by sheep and performance of growing-fattening beef cattle fed the ensiled crops. Plant populations at harvest ranged over years from 53 000 to 63 000 plants ha−1 for conventional seeding and from 94 000 to 151 000 plants ha−1 for the dense seeding rate. Dense seeding increased whole-plant dry matter yield each year. Only in 1 year (1979) did dense seeding reduce the yield of dry matter in the whole ear or grain (P < 0.01). In the same crop year (1979) dense seeding reduced the dry matter and crude protein contents of the silage (P < 0.01) and the digestibilities by sheep of the dry matter and nitrogen were lower (P < 0.01) than for the conventionally seeded crop. In 2 years (1978 and 1979), when the silages were fed ad libitum with only a protein-mineral-vitamin supplement, the daily silage dry matter intake by beef cattle was lower (P < 0.01 or P < 0.05) and in 1979 the average daily gain (1.06 vs. 1.14 kg d−1) was lower (P < 0.01) with silage from the dense seeding. There were no significant differences in beef performance parameters (silage dry matter intake, daily gain, and efficiency of silage conversion to daily gain) in the third year when the silages were fed with ground barley. Dense seeding of corn for silage resulted in more beef production per hectare and provides a means of reducing productivity loss due to birds feeding on the ripening ears of corn.
