Feeder Space

The effects on broiler performance of different floor, waterer, and feeder spaces and light treatments were estimated. Increased bird density resulted in a reduction in body weight, poorer feed conversion, reduced carcass quality and a reduction in monetary returns per bird started. Feeder space effects were inconsistent. Waterer spaces examined had little effect on bird performance. Light treatments studied revealed that cycles of 1 h of light with 3 h of darkness resulted in slightly superior feed conversion compared with cycles of 3 h of light and 1 h of darkness.

Broiler-type turkey poults were placed sex-separate in floor pens (60 birds/pen; ca. 5.5/m2) of an environment-controlled house. All birds received corn-soybean meal based rations paralleling commercial practice. Treatments were imposed at 5 wk of age and involved either debeaking alone (controls) or its combination with toenail-clipping (6 pens/sex/treatment). Body weight of nail-clipped turkeys was less at 6 and 10 wk than found with controls; however, the converse was observed by slaughter at 14 wk. Conversion of feed consumed during the 6 to 10- and 10 to 14-wk intervals was more efficient with nail-clipped than control birds. Mortality was similar between both groups from starting through to the finishing period whereupon noticeably fewer deaths occurred with nail-clipped as opposed to control turkeys. Dressed carcass yield was greater when nail removal was performed than not. A 40% reduced incidence of utility grades indirectly suggested that this yield advantage was due to less "on the line" trimming during processing. Conformation, fleshing and finish grades were unaltered. Both sexes responded comparably. All advantages arising as a consequence of toenail-clipping could be explained in terms of reduced flock activity.

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.

The Many

The Chicken broiler is a type of superior race chicken that has high genetic properties, especially in growth. The use of herbs as medicines in medicine is now starting to increase, which is evident from the many traditional drugs manufacturers on the market. One of the herbs that can be used as an antibiotic for livestock is basil (Ocimum sp). Basil contains beta-carotene (provitamin A), which supports the function of vision, improves antibody function (influences immune function), protein synthesis to support growth process and as the antioxidant (Adnyana and Firmansyah, 2006). The purpose of this study was to determine the effect of the addition of basil leaves flour up to 12% level against broiler performance. The experiment was carried out experimentally using a completely randomized design (CRD). The results of statistical analysis showed that the addition of basil meal powder into the feed did not affect to feed consumption between levels (P> 0). The result of the statistical analysis showed that the addition of basil meal powder into the feed had no effect (P> 0,05) to the increase in body weight. The result of the statistical analysis showed that the treatment with the addition of basil powder into the feed had no effect (P> 0,05) to feed conversion. The result of this research can be concluded that the addition of basil powder into feed up to 12% level did not give significantly different effect on production performance such as feed consumption, body weight gain and feed conversion of the broiler.

SummaryThirty-nine adult ewes of identical body size and age were randomly taken from the Chokla breed. They were divided into four groups which were allowed water once in 24, 48, 72 and 96 h. Seven ewes from each of the first, third and fourth groups were mated for the first time in the spring and for a second time in winter, so that they lambed in the monsoon and summer season respectively. All the ewes were maintained on uncultivated pasture. Watering once in 72 and 96 h caused body weight loss up to 26%, compared with those watered daily. The ewes which failed to maintain pregnancy lost more than 30% of their body weights due to watering only once in 96 h and there were about 43 and 100% lambing in the first and second breeding cycle of the same ewes. The remaining groups displayed 100% lambing. The water-intake increased significantly in the third month of pregnancy in the group allowed water daily and water consumption was found to be about 13% of body weight, whereas the values for those watered once in 72 and 96 h were 9 and 8% respectively. The water-deprived animals were able to drink up to 32 % of their body weights within 2–3 min. It is concluded that breeding ewes could be watered once in 72 h without any loss of lambing during summer.

Abstract Technology that facilitates estimation of individual animal intake rates in group-housed settings will result in improvements in animal production and management efficiency. Estimating intake in pasture settings may benefit from models that use other variables as proxies. Relationships among dry matter intake (DMI), animal performance variables, and environmental variables to model DMI were investigated. 202 animals were studied in a drylot setting (153 bulls for 85 days and 55 steers for 55 days) using VYTELLE SENSETM In-Pen-Weighing and Feed-Intake nodes. A machine learning model was calibrated using: DMI, sex, age, full body weight, ADG, water intake, water visit frequency and duration. DMI was positively related to full body weight (r = 0.39, P < 0.001), water intake (r=0.23, P < 0.001), and ADG (r=0.18, P < 0.001). In addition, DMI had significant but weak correlations with water visit frequency (r=0.031, P < 0.001). DMI exhibited weak negative relationships with maximum air temperature (r=-0.094, P < 0.001) maximum relative humidity (r=-0.056, P < 0.001), net radiation (r=-0.040, P < 0.001), and precipitation (r=-0.022, P < 0.001). Weak positive relationships were observed between DMI and maximum wind speed (r=0.031, P < 0.001) and direction (r=-0.022, P < 0.001). The model was validated with resultant average RMSE of 1.06 kg for daily predicted DMI compared to measured daily DMI. In addition, when daily predicted DMI was averaged for each animal, the accuracy of model results improved with RMSE of 0.11 kg. Study results demonstrate that inclusion of water intake and animal performance variables improves predictive accuracy of DMI. Validating and refining the model used to predict DMI in drylots will facilitate future extrapolation to larger group field settings. Vytelle and its logo are trademarks of Vytelle, LLC.

A test has been carried out in rats of the possibility of measuring with the aid of doubly labeled water (D2O18) the following components of the material balance of an animal: output of CO2 and water; intake of oxygen, food and water. The items of information used for the measurement were a) isotopic analyses of initial and final blood samples, b) composition of the diet with respect to percentage protein, carbohydrate and fat, c) initial and final body weight, d) final percentage body water. Initial percentage body water obtained from a by the volume of dilution principle could substitute for d. CO2 and water output were estimated isotopically; O2 consumption, from the CO2 output and dietary R. Q.; food intake, from CO2 output and dietary composition; water intake, from the difference between water output and dietary metabolic water. A rough correction for storage of materials was made from the change in body weight. The average difference between observed values for each of the above components of the material balance and values calculated by the isotope procedure was less than 10%. The fact that dry air was supplied to the animal in the metabolism chamber used to obtain the observed values probably favored better agreement between calculated and observed values for water intake and output than would prevail in ordinary moist air.

Objective: Present study was undertaken to investigate the nephroprotective activity of whole plant ethanol extract of Biophytum sensitivum Linn. DC (B. sensitivum; EEBS) on gentamicin induced-nephrotoxicity in Wistar albino rats.Methods: Animals were divided into five groups, containing six animals in each. Gentamicin (GM) 100 mg/kg/d; i. p., was given to all groups except normal control to induce nephrotoxicity for a period of 8 d in rats. Animals in Group I served as control and Group II as GM-treated or nephrotoxic control. Group III received standard quercetin (50 mg/kg; p. o.); group IV received EEBS (250 mg/kg; p. o.) and group V received EEBS (500 mg/kg; p. o.), for 8 d. Several renal functional tests and injury markers such as a change in body weight, water intake, urine volume and pH, urinary levels of total protein, albumin, sodium, potassium, calcium and magnesium were measured. Different hematological parameters including, red blood cells (RBC), hemoglobin (Hb), packed cell volume (PCV), mean corpuscular haemoglobin (MCH), white blood corpuscles (WBC), lymphocyte, monocyte, polymorphs and eosinophil were also analyzed.Results: The results revealed that co-administration of EEBS at 250 and 500 mg/kg significantly reduced the urinary excretion of total protein (4.05±0.04, 3.53±0.05 g/dl), albumin (0.81±0.08, 0.71±0.00 g/dl), calcium (8.05±0.05, 7.81±0.06 mg/dl) and magnesium (0.79±0.05, 0.77±0.06 mg/dl) respectively. EEBS treatment in group IV and V animals produced a significant increase in body weight (2.58±0.17, 2.52±0.22 g), water intake (17.35±0.82, 17.87±0.86 ml/24 h) urine output (7.24±0.15, 7.88±0.08 ml/24 h), compared to animals in group II. Co-therapy with both doses of extracts also showed significant increase in RBC (6.85±0.31, 7.10±0.43 million/mm3) Hb (13.96±0.21, 13.83±0.31 g/dl), MCH (20.45±0.49, 20.67±0.51 pg) and PCV (38.29±0.42, 38.53±0.20%) levels, whereas WBC (8.24±0.21, 8.15±0.10 1X103/mm3) and polymorphs (14.19±0.20, 14.05±0.11%) levels were found to be significantly reduced respectively in animals than those in toxic control group.Conclusion: This study substantiated and confirmed the ethnomedical usefulness of B. sensitivum as a nephroprotective and antioxidant agent.

A 21-day experiment with day-old broilers was conducted in order to assess the effect of phytase supplementation to different cereals-soybean meal based diets on broiler performance and tibia ash. Diets were formulated to contain 4 different cereals (maize, wheat, triticale and barley), 2 levels of dietary calcium (0.6 and 1.0%) and 3 levels of supplemental phytase (0, 500 and 1 000 PU/kg). Supplemented phytase had beneficial effects on broiler performance. It significantly increased body weight gain (P < 0.0003) and feed consumption (P < 0.0361) by 6 and 7% in comparison with the control groups, respectively. No influence on feed conversion ratio and tibia ash was detected. Both body weight gain and feed intake were also significantly influenced by different cereals (P < 0.0001 and 0.0348, respectively). The increasing dietary calcium level resulted in a significant increase in body weight gain (P < 0.0024) and tibia ash (P < 0.0016). Effects of 500 and 1 000 PU/kg were not statistically different between themselves.
