Alfalfa Hay

Alfalfa hay treated with a commercial preservative containing 80% propionic and 20% acetic acid was evaluated as a feed for horses. In a two-choice preference test, horses preferred untreated hay (P < 0.05). When yearlings were fed either treated or untreated hay for 1 mo, there was no difference in feed consumption or weight gain indicating that when given no choice, horses find hay treated with propionic and acetic acid acceptable.

Potential Interactions

The performance of growing pigs fed 2 mg kg−1 of one of several Fusarium graminearum metabolites (sambucinol, 15-acetyldeoxynivalenol, 3-acetyldeoxynivalenol, culmorin, dihydroxycalonectrin) with and without 6 mg kg−1 deoxynivalenol (DON) was examined in three preliminary studies. The only significant effects (P < 0.05) were seen in feed consumption, weight gain and feed efficiency due to the presence of DON in the diet. In addition, the appearance and degree of folding of the esophageal portion of the stomach were also different between pigs fed the DON-free and DON-contaminated diets, though the degree of significance varied between trials. Some small differences were seen in growth and feed consumption for certain metabolites, notably sambucinol and culmorin, with and without DON, but they were not significant (P > 0.05). The data indicate that, at the dietary concentrations used, the fungal metabolites tested in combination with DON do not interact with DON in growing pigs to any marked degree.

One thousand day-old male chicken broilers housed in 16 floor pens to 42 d of age were used to study the effect of stevia on weight gain and feed consumption. The experimental design was a randomized complete block consisting of four diets (0%, 0.0085%, 0.0425% and 0.085% stevia) each replicated four times. Stevia did not appear to improve feed consumption or weight gain of broilers when used as a feed additive at the concentrations tested in this study.

Dietary Treatments

An experiment was conducted with commercial broilers to investigate the effects of feeding citric acid, acetic acid and their combination on their performance and to determine the economic competence of using citric acid and acetic acid in broiler rations. A total number of 108 one day old straight run broiler chicks were distributed to four dietary treatments i.e. 0 % citric or acetic acid (A), 0.5% citric acid (B), 0.5% acetic acid (C) and their combinations 0.5% citric acid and 0.5% acetic acid (D). The birds were reared in cages. Body weight gains, feed conversion ratio (FCR), mortality, dressing yield and carcass characteristics were recorded. The performance showed significant increase in body weight gain (P<0.05) when compared with the control during 0-5 weeks of age on 0.5% citric acid (B). Feed consumption increased (P<0.05) at 2nd and 3rd weeks of age on 0.5% citric acid (B). Feed conversion was found higher (P<0.05) during 0-5 weeks of age in treatment B when compared to those of the other treatments. Carcass characteristics were not affected by dietary treatments. The highest mortality was found in treatment A and treatment C due to excessive hot. It may be concluded that use of 0.5% citric acid in the diet of broilers may have better performance in respect of live weight gain and feed conversion.

The Relationship

The responses and tolerances of early-weaned piglets to transport are not well documented. It is believed that the additive stress incurred by transporting early-weaned pigs predisposes them to increased disease risk and compromised performance. The objective of this work was to investigate the relationship between two primary transportation stressors, duration and temperature, and their effects on piglet performance. Prior to housing on flatdecks at 30°C, transport was simulated by placing 17-d (± 1 d) old weaned piglets into wooden boxes of dimensions 1.2 × 1.2 × 1 m (space allowance range 0.18 to 0.36 m2 pig–1) with straw bedding. Two trials were conducted. In each trial, 96 piglets were randomly mixed in groups of four and assigned to the following simulated transport durations: no transport (control), 6 h, 12 h (Trial 2 only) and 24 h. Piglets undergoing transport simulation were kept at one of the following temperatures 20, 25 (Trial 1 only), 30 and 35°C. There was a significant interactive effect between transport duration and temperature upon liveweight change in the first 24 h in both trials (P < 0.01). The animals that incurred the greatest liveweight deficit after weaning relative to untransported control groups were predominantly either those that had been transported for 24 h at high transport temperatures (35 and 30°C) or those transported for 6 h at 20°C in Trial 1 and 35°C in Trial 2. The effect of simulated transport was measureable for up to 5 d post-transport. However, by 14 d post-transport there was no detectable influence of transport treatment on feed consumption or weight gain (P > 0.05). The study found piglets are able to recover and perform adequately in the early post-weaning period if extremes of transport duration and temperature are avoided.

Growth Trial

A digestibility trial with 24 mature wethers and a growth trial with 54 weaned lambs were conducted to evaluate the utilization of ground diets containing varying proportions of grass and legume hay relative to a 90% grain diet. The forage and grain diets were (1) 100% crested wheatgrass hay (CWG); (2) 75% CWGand25% alfalfa hay (AA); (3) 50% CWGand50% AA; (4) 25% CWGand75% AA; (5) 100% AA; and (6) 90% barley and 10% barley straw. Even though apparent digestibility of dry matter (DM) and fiber fractions of AA-containing diets was lower than that of the grain diet and the 100% CWG diet, weight gain was similar for all diets. Consumption of the grain and 100% CWG diet was lower (P < 0.05) than that of the 100% AA diet. Conversion of feed DM to liveweight gain for lambs fed the grain diet was only 4.9 and was lower (P < 0.05) than that of the forage diets, which ranged between 6.1 and 7.0. Dressing percentages of lambs at slaughter for the animals fed the grain and 100% AA diet were 45.0 and 43.2%, respectively, which were higher (P < 0.05) than that of animals fed the CWG-containing diets. These data suggest that inclusion of AA in CWG diets did not result in the expected positive associative effect on growth and feed efficiency in sheep.

<p>The experiment was carried out to observe the effect of sires and diets on the growth traits of Turi duck up to the age of eight weeks. There were five sires and 25 dams which produced 151 offspring used in the experiment. Three diets with equal nutrient balance but different concentration P1: {CP:EM= 1:145,EM 2482 kcal/kg:protein 17%}; P2 {CP:EM= 1:146 EM 2628 kcal/kg:protein 18%}; dan P3 {CP:EM= 1:144 (EM 2774 kcal/kg: protein 19%} were then applied. Phenotypic datasets on body weight, body weight gain, feed consumption and feed conversion parameters were collected. The result showed that sire had no effect on body weight, body weight gain and feed conversions of the offspring. Different diets, on the other hand affected feed consumption (lowest P3:822.37 g/head/weeks). Interactions between sires x age were then found to be significantly affected feed consumption.</p><p><br />(Key words: Sires, Diets, Growth, and Turi duck)<br /><br /></p>

Seventy-two steers (289 kg) were offered ad libitum cubed alfalfa hay, cubed timothy hay, or barley silage supplemented with incremental levels of xylanase (IU) and cellulase (FPU), combined in a ratio of 1 IU:0.04 FPU. For alfalfa hay, low and moderate levels (900 to 4733 IU kg−1 DM) increased weight gain by up to 30% (P < 0.10), whereas, for timothy hay, the highest level (12 000 IU kg−1 DM) improved gain (P < 0.10) by 36%. No response to enzymes was observed for barley silage. Fibrolytic enzymes improve weight gain of cattle but optimal enzyme levels depend upon the type of forage.

The objective of the researh was to study the effect of additions soybean meal in ration on the feed consumption, daily weight gain and feed convertion in Simmental cattle. The experiment used eight male Simmental cattle around 2 years old with an average weight of 198,65 ± 14,57 kilograms. The cattle kept for 35 days and given rations P0 (rations ranchers) and P1 (rations plus soybean meal). Data was obtained, then analyzed using independent sample t-test assisted with SPSS version 17.00 software. The result showed that the addition of soybean meal did not affect on dry matter consumption, daily weight gain, and feed convertion but, the crude protein consumption was increased.

Two trials were conducted to determine feed color effects on broiler performance. A completely randomized design was used. Trial 1 included four treatments: control (complete broiler starter diet), red, green, and blue; and Trial 2 included four treatments: control, orange, yellow, and purple. Each trial had 4 treatments with 4 replicates (60 birds/treatment) fed to 240 male Cobb 500 broilers during a 21 d grow out. Data were analyzed using the GLM procedure. In Trial 1, there were no treatment effects on average body weight, body weight gain, and feed consumption (p > 0.05). Adjusted feed conversion for control (1.23) was less than red (1.27; p = 0.001) and green (1.26; p = 0.009), with blue (1.25; p = 0.056) tending to be different during the experimental period. In Trial 2, there were no treatment effects on average body weight, feed consumption, and adjusted feed conversion during this study (p > 0.05). Body weight gain between d 1 to 14 for purple (490.78 g/bird) was more than orange (467 g/bird; p = 0.013) and yellow (461 g/bird; p= 0.004), with control (474 g/bird; p = 0.052) tending to be different. Results indicate that these feed colors had some, albeit limited, influence on broiler performance parameters.

Studies were made on forestomach contraction frequencies as affected by diet (brome hay, alfalfa hay, alfalfa silage and barley concentrate diet), acute cold stress and acute psychological stress. Four 15-mo-old steers fitted with ruminal fistulae were used in a 4 × 4 Latin square design. Diets did not influence contractile frequencies of the forestomachs, and did not interact with the effects of the stresses. Acute cold stress and psychological stress both produced significant increases of forestomach contraction frequencies and of heart rate.
