The effect of monensin ongrowth and feed utilization was studied in male calves of milk breeds, mainly Ayrshire. After weaning they were kept in an indicated loose-housing type shed divided into four strawbedded pens. The experiment was started at the age of 2—3 months and lasted 16 weeks. A concentrate mixture and grass silage were offered ad libitum. The concentrate given to the test groups had a monensin content of 35 ppm. Monensin lowered the feed consumption: in the control and test groups the intake of concentrate was 3.9 and 3.7 kg DM, respectively, the silage intake was 0.8 and 0.7kg DM, the fattening feed unit intake was 4.65 and 4.36, and the ME 54.4 and 50.9 MJ per day. The liveweight gain was not affected (1328 and 1329 g/d). Monensin improved the feed conversion rate by 6 %. The animals in the test groups were slightly cleaner than the animals in the control groups.

Growth performance and carcass characteristics of capons (castrated cockerels) from three breeds/strains locally presented in Slovenia and Austria were investigated. Growth and feed consumption data were collected for a 156-d and 199-d period, when randomly chosen animals were slaughtered and their carcasses dissected. The feed conversion rate in barred Prelux, Sulmtaler and Styrian capons for the whole growing period was 6.24 kg, 6.32 kg and 7.53 kg, respectively. Average body weight in barred Prelux and Styrian capons increased only in the first 156 days of age, but not further on. Cumulative mortality rate in Sulmtaler capons was 19.05 % and was 2.7- to 4.4-fold higher as compared with Styrian and barred Prelux capons (6.90 % and 4.31 % respectively). Sulmtaler capons had the lowest abdominal fat content. Barred Prelux capons, as compared to capons from other two breeds were characterized by higher pre-slaughter weight, higher carcass weight and higher dressing out percentages. This indicates that the layer type barred Prelux cockerels have a potential to be as capons put to profitable use.

The objective of our study was to test amaranth grain or dried biomass in the diet for broiler chickens as a resource of protein replacing animal protein. Further, the effect of amaranth on broiler performance, carcass characteristics and meat quality were assessed in a feeding trial. The experimental groups of broilers were fed feed mixtures with crude amaranth grain (AC), heat processed amaranth grain (AP) or dried above-ground biomass (AB). Control groups (C) received the diet containing animal proteins. The results obtained in the experimental groups of broiler chickens can be compared to the control group in all the production indicators under investigation. On day 42 of the experiment, live weight (g) of female broilers ranged from 2 205.1 ± 152.5 (AP) to 2 254.0 ± 136.5 (C), and that of male broilers from 2 375.1 ± 233.0 (AC) to 2 506.0 ± 286.0 (C). Feed conversion ranged from 1.80 kg in control group of male broiler chickens to 1.91 kg in experimental group of male broilers (AB). Percentage yield in female broiler chickens ranged from 70.8 ± 1.74 (AB) to 72.4 ±3.34(AC) or 72.4 ± 1.98 (C), and in male broilers from 72.8 ±3.55(AP) to 75.1 ±2.44(AB). Our results showed that amaranth can fully replace meat-and-bone meals in the diets for broiler chickens.

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.

This study, aimed to determine the effects of different light regimen and day/night feeding on some performance criteria of 1104 broiler chickens during summer season. At the beginning of second week they were separated according to their sexes, and experiment had 2 × 6 replications. The 1st group, as control, received continuous lighting (daylight + lightening during night) and fed ad-libitum. The 2nd group was treated with continuous lighting too, but they had no access to feed between10:00 and 16:00 o’clock during the last three weeks. The 3rd group was also exposed to continuous lighting but had no access to feed between10:00 am and 16:00 pm. Fourth group received continuous lighting but had no access to feed between 24:00 pm and 06:00 am. Fifth group received continuous lighting, but they were not fed between 24:00 pm and 06:00 am during the last three weeks of experimental process. Sixth group had no access to feed box during 24:00 pm and 06:00 am, when they had not been exposed to light as well. There were no notable differences in live weight gain of male and female birds for all treatment groups, and similarly differences among feed consumption and feed conversion ratios were not remarkable statistically regardless of the sexes of chickens. There were significant differences in hot-cold carcass yields of the 3rd and 6th treatment groups for male birds and 6th treatment group for female birds. The differences for carcass weights of male birds were statistically significant and 3rd and 6th treatments groups were tend to be relatively higher than the other treatment groups. The differences among treatment groups for carcass weights of female birds, however, were not significant and similarly the effects of the treatments on the mortality rate was found to be in significant for same birds. Lightning (24h) and feeding ad - libitum affected the performance of the birds adversely, whilst restricted feeding and lightning process reduced the yield-loss the animals during the summer season.

Milk Feeding

The aim of the research was to study whether the anticipated added weight gain from ad libitum acidified milk feeding compared to restricted milk feeding during the preweaning period can be maintained after weaning until slaughter. The study was conducted by comparing first the growth performance of eleven bull calves until an average age of 126 days (Phase 1) when the five calves were fed acidified milk either ad libitum (FM) for 17 weeks or when six calves were given acidified milk restrictively (5 l per day, RM) for nine weeks. Bulls had ad libitum access to grass silage and concentrate. Secondly, the performance of bulls having an average age of 175 days until slaughter (at an average age of 429 days) at a carcass weight of approximately 290 kg was assessed (Phase 2). All animals were fed grass silage ad libitum and concentrate at a level of 620 g kg-1 of dietary dry matter. Calves fed acidified milk ad libitum grew significantly (P < 0.01) faster than those fed restrictively during the first nine weeks of Phase 1 (1003 vs. 725 g per day). The bulls in the RM group grew a little but not significantly faster during Phase 2, the growth rates being 1197 vs. 1207 g per day. The feed conversion, weight (535 vs. 533 kg at slaughter) and slaughter results were equal. Similarly the life-time gains did not differ being 1174 (FM) and 1141 (RM) g per day, respectively. It can be concluded that the improved performance during early life did not improve growth during the fattening period.;

Abstract. Nugroho RA, Hardi EH, Sari YP, Aryani R, Rudianto. 2019. Growth performance and blood profiles of striped catfish (Pangasianodon hypophthalmus) fed leaves extract of Myrmecodia tuberosa. Nusantara Bioscience 11: 89-96. The application of plant extract in the aquaculture field is gaining momentum. This study aimed to determine the effects of M. tuberosa Jack leaves extract on the growth performance and blood profiles of striped catfish (Pangasianodon hypophthalmus). 400 fish with an initial average weight of 1.54 ± 0.02g were randomly divided into five groups and fed with different concentration of M. tuberosa Jack leaves extract (0.25, 0.5, 1, 2%) and control diet for 80 days. Growth performance, feed conversion rate, feed efficiency, survival rate, morphometric, and hematological profile of the fish were evaluated at the end of the trial. The results found that fish fed 0.5-1% concentration had significantly higher (P<0.05) growth, feed conversion rate, feed efficiency, morphometric value, survival, white blood cell, hemoglobin, neutrophil, lymphocyte, and monocyte than control. Meanwhile, supplementation of 2% MTE in the diet of fish reduced growth, feed utilization, viscerosomatic index, and morphometric values but increased red blood cell. All the supplemented diets decreased platelet of fish. The findings indicated that supplementation 0.5-1% of MTE is beneficial to the growth and blood profile of fish through the increment of growth indices, feed utilization, white blood cell, hemoglobin, neutrophil, lymphocyte, and survival rate of fish.

Friesian Cows

An experiment was performed with 22 Friesian cows, using a double reversal design with two treatments and one similar sequence for the two groups. The lengths of the standardization period, adaptation periods, test period and post-test period were 4, 1, 8 and 4 weeks, respectively. During the standardization and post-test periods the cows received pre-wilted grass silage ad libitum and a small amount of field-dried baled hay. In the test period hay was given ad libitum and the amount of grass silage was restricted. A concentrate mixture (barley, oats, minerals) was given daily to each cow at the rate of 0.3 kg/kg 4 % milk. During the standardization and post-test periods the mixture contained one percent of untreated urea and during the test period 2.5 % of untreated or treated urea. The urea had been treated with 1.5 % formaldehyde on a weight basis. The concentrate mixture was fed individually to each cow, but group feeding was used for the roughage. Among the cows producing more than 15 kg of 4 % milk a day, those receiving formaldehyde-treated urea had a significantly (P< 0.01) higher milk yield, and the fat content of their milk was significantly (P< 0.05) lower than the group receiving untreated urea. Among the cows producing less than 15kg of 4 % milk/day, the group given treated urea had a significantly (P

Comparison Period

This study investigated the effect of a polyol mixture or molasses treated beet pulp on the feed utilization, milk yield and blood values. 24 cows were divided into 3 groups. Hay was given at 2 kg/d, silage ad lib. and concentrate mixture at 78 kg according to the milk yield. The control group had grain (barley-oat) concentrate mixture, the molasses group had grain supplemented with 29 % dried molasses beet pulp and for the polyol group grain was supplemented with 25 % dried beet pulp treated with mixture of sugar alcohols. A 2 weeks standardisation period was followed by 12 of comparison. 12 of the cows were also in a digestibility trial in the later part of the comparison period. Feed intake was heavily reduced in the molasses group and hence the milk yield was significantly lower (P < 0,05) than in the polyol or control groups (19,5, 21,2 and 21,2 kg FCM/d). The mean consumption of polyols was 483 g/d and that of sugars from the molasses beet pulp was 410 g/d. The feed utilization was significantly lower (P < 0,05) in the control group than in the polyol or molasses groups. The consumptions of f.f.u./kg FCM were correspondingly 0,407, 0,375 and 0,373. Digestibility of nitrogen free extracts was significantly higher for the polyol group than for the control group (81,4 and 78,1 %). For molasses group digestibility of NFE was 78,5 %. Digestibility of OM was correspondingly 76,2, 73,6 and 74,3. Rumen butyric acid formation was higher in the polyol group than in the molasses or control groups, although the differences were not statistically sinificant. The blood and plasma parameters studied were haemoglobin, PVC, ketone bodies in blood, glucose, total protein, urea-N and uric acid in plasma. Plasma urea-N was higher (P < 0,01) in the control than the polyol or molasses groups. In glucose or ketone bodies concentration there were no treatment induced differences.

A broiler feeding trial was conducted to determine the optimum replacement value of sesame (Sesamum indicum L.) meal for soyabean in maize-soyabean diets. A total of 252 day-old Anak 80 strain broiler-type chicks were used. Three replicate groups of 14 birds each were randomly allotted on six treatment diets containing 0, 10, 15, 20, 30 and 40% of sesame meal in the diets. Feed and water were provided ad libitum. Results showed that broiler birds fed up to 15% level of sesame meal in diets performed significantly (P<0.05) better than those fed on control diets for all the parameters studied. Feed consumption and feed efficiency values were also significantly lower for birds fed 15% sesame meal diets compared to those on control. However, sesame meal al 30 and 40 percent in diets significantly (P<0.05) depressed growth performance of broiler birds. It was found from this study that, up to 15% sesame meal could be used in maize-soyabean broiler diet without adverse effect on growth parameters.

The goal of this research was to investigate the effect of various levels of organic selenium (selenized yeast) on the weight gain and feed utilization of chicken in fattening. The experiment was carried out on 120 chicken of line hybrid Hybro-PN, divided into four groups (treatments), lasting six weeks. All groups of chicken were fed complete mixtures, while selenium was added to feed in the form of selenized yeast, in quantities of 0 (Group I); 0.3 (II) 0.6 (III), or 0.9mg/kg (IV). Chicken were measured, and care was taken to keep groups uniform (Groups: I - 36.17g; II - 37.01g; III - 37.16g, and IV 36.59g). During the experiment, every seven days, body weight of all animals was measured, as well as feed consumption for each experimental group. At the end of fattening, the highest body weight was established for chicken in Group III (2647.50g), followed by chicken in Groups II and IV (2595.89 and 2526.55g). Mentioned values were statistically significant (PO.01) by chicken and groups (2309.lg). Average daily feed consumption during the whole fattening period was highest in Group III, and lowest in Group I. For the last week of fattening it amounted to 196.38g (Group III), i.e. 179.41g (Group I). However, for chicken in Groups II and IV, these values were somewhat lower, as compared to chicken in Group III (190.50 and 185.15g). Food consumption per 1 kg gain was lowest in groups fed rations with added organic selenium (Group II - 1.65; III and IV - 1.67). Chicken in group I had the worst feed conversion (1.73).
