Abstract

This experiment was conducted to study the effects of katuk leave meal on sexual maturity in Japanese quail.  Three hundred female Japanese quails, with 4 weeks age, were assigned into a completely randomized design with 4 treatments i.e., R1 (diet with neither katuk leave meal nor cholesterin), R2 (diet without   katuk leave meal + 0.10% cholesterin), R3 (diet with 15% katuk leave meal without cholesterin), and R4 (diet with 15% katuk leave meal + 0.10% cholesterin). The parameters measured were estradiol hormone in plasma, and age maturity (five percent henday production). Estradiol hormone was measured with Radioimmunoassay. The data were collected and analyzed by using completely randomized design. The results showed that the addition of 15% katuk leave meal in the diet significantly decreased the estrogen concentration (P<0.05), so that slow down on the age maturity of female Japanese quail.

Abstract

An experiment was conducted to study injection of pregnant mare serum gonadotrophin (PMSG) and human chorionic gonadotrophin (hCG) as superovulation agent in gilts to improve thyroid hormone and blood metabolites concentraton. In this experiment, 48 gilts were assigned into four groups of twelve gilts injected with PMSG dan hCG dose levels of 0, 600, 1200 and 1800 IU/gilt. Injections were conducted three days before estrus. During  gestation, gilts were placed in colony pigpen. On days 15, 35, and 70 of gestation blood collected to determine triiodothyronine, tetraiodothyronine, tryglicerides, glucose, protein and bood nitrogen urea concentration. The resuts showed that superovulation dose levels of 600 to 1200 IU/gilt increased concentration of thyroid hormone (triiodothyronine and tetraiodothyronine/thyroxin) and blood metabolite (triglycerides, glucose, and protein), but decreased blood urea nitrogen in gestation ages 15, 35, and 70 days.  It is concluded that superovulation with dose of 600 to 1200 IU can improve of gilts metabolite hormone and blood metabolites.

Abstract

Sixty gilts with average body weight of 107.80 + 5.10 kg were used in an experiment to study the use of PMSG and hCG as superovulation agent to increase piglet production. In this experiment 60 gilts were assigned into a completely randomized design with 4 treatments of superovulation with dose level 0, 600, 1200 and 1800 IU/gilt. Injections were conducted 3 days before estrus. During gestation, gilts were placed in single pigpen, and maintained to term. The parameters were birth weight, preweaning growth and mortality. The results showed that superovulation dose levels of 600 and 1200 IU/gilt increased the piglet birth weight, litter size, preweaning growth and piglet production at 90 days. It is concluded that superovulation with dose levels of 600 to 1200 IU can improve productivity. (Animal Production 8(1): 8-15 (2006) Key Words :   Superovulation, gilts, piglet production

Abstract

The objective of this study was to evaluate the use of mineral soap, organic mineral and roasted soybean supplementations to improve productivity in ruminant animals. Thirty two Garut Sheep (initial body weight 22.38 ± 3.56 kg) were assigned into a randomized block design with eight treatments. Body weight was used as a block (4 blocks). Eight rations evaluated in this trial were FO: basal diet + fish oil, CO: basal diet + corn oil, CaFO: basal diet + calcium soap of fish oil, CaCO: basal diet + calcium soap of corn oil, ZnFO: basal diet + zinc soap of fish oil, ZnCO: basal diet + zinc soap of corn oil, RS: basal diet + roasted soybeans, MM: basal diet + mineral mix. The experimental diets were fed for 8 weeks. The result of the experiment showed that calcium soap improved animal growth better than did zinc soap. Daily gains of sheep fed FO (99 g/d), CaFO (114 g/d), CaCO (103 g/d), RS (105 g/d), and MM (103 g/d), diets were higher (P < 0.01) than those of sheep fed CO (86 g/d), ZnFO (88 g/d), and ZnCO (53 g/d) diets. Dry matter intake of sheep fed CO (903 g/d), CaCO (947 g/d), RS (933 g/d) diets were higher (P < 0.01) than those fed FO (820 g/d), CaFO (856 g/d), ZnFO (847 g/d), ZnCO (785 g/d), and MM (805 g/d) diets. Dry matter digestibility of CO (70%) and CaFO diet (76%) were higher (P < 0.01) than other diets. Nitrogen retention of sheep fed CaFO (11.8 g/d), RS (12.2 g/d), and MM (13.2 g/d) diets were higher (P < 0.01) than those fed FO (10 g/d), CO (10 g/d), CaCO (9.8 g/d), ZnFO (9.0 g/d), and ZnCO (9.0 g/d) diets. Organic mineral, calcium soap of fish oil, calcium soap of corn oil, and roasted soy bean supplementation increased daily gain up to 105 g/d. It was concluded that calcium soap, organic mineral and roasted soybean improved growth of sheep.Key words : soap, oil, mineral, roasted soy bean, sheep

Abstract

The n-hexane fraction of “jaloh" extract could reduce detrimental effects of heat stress on broiler chicken. An experiment was conducted to study morphometric of small intestine villi (duodenum, jejunum, and ileum) and performances of broiler exposed to heat stress on 33±1oC for 4 hours/day and given extract n-hexane of “jaloh" bark (EHJ) with doses 5, 10, and 20 mg/kg body weight (BW). Thirty broilers aged 20 days (Cobb strain) were randomly divided into 5 groups of treatments. The first treatment group was external control namely chickens without heat stress and without EHJ administration (tCP). The second group of treatment was internal control representing chickens exposed to heat stress without EHJ administration (CP). The third, fourth, and fifth treatment groups consisted of chickens exposed to heat stress and given 5 (CP+EHJ5), 10 (CP+EHJ10), and 20 mg/kg BW of EHJ (CP+EHJ20), respectively. Heat stress and “jaloh" extract were implemented every day. “Jaloh" extracts were given 1 hour before temperature in the cage was raised. Results showed that heat stress decreased weight gain and height of jejunum villi, and increased feed conversion ratio. The dose of 10 mg/kg BW of EHJ can improve performance of broiler chickens and morphometric of small intestine villi. Key words: heat stress, Salix tetrasperma, performance, broiler

Abstract

Phytate is commonly high in cereals grain. This compound can be extracted with acid solution. The purpose of this study is to extract phytic acid from pollard using acetic acid at the concentration of 0.1, 0.5, 1, and 5%. Pollard was fractionated using vibrator ball mill to evaluate the distribution of phytic acid in the particle of pollard. One percent of acetic acid was used to extract phytic acid from pollard at ratio of 1:1; 1:1.5; 1:2; and 1:3. The fraction having particle size of 16, 30 and 50 mesh had similar phytic acid content. The results indicated that phytic acid content of these fractions was higher than that of 100 and 400 mesh fractions. Whole pollard had higher phytic acid content than its fractions. Phytic acid in pollard can be extracted by 1% acetic acid solution. Extraction of phytic acid from pollard using 1% acetic acid solution at ratio of 1:3 produced 23.83 g/kg. Key words: extraction, phytic acid, pollard, acetic acid

Abstract

Zinc and Cu have important roles in growth and immune system, but their bioavailability are low due to the phytic acid content in poultry diet. This experiment was conducted in order to obtain the best combination of phytase, Zn, and Cu as growth stimulants for broiler fed diet containing phytic acid. Two hundred eighty eight Day Old Chicks unsexed were allocated into nine treatment diets with four replications (eight chicks in each replicate). The birds were raised up to 42 days old. Combination of the treatment diets were: R1 (positive control), R2 (negative control), R3 (R2 + 132.70 ppm ZnO), R4 (R2 + 286.16 ppm CuSO4), R5 (R2 + 132.70 ppm ZnO + 286.16 ppm CuSO4), R6 (R2 + phytase 1000 FTU/kg), R7 (R2 + phytase 1000 FTU/kg + 132.70 ppm ZnO), R8 (R2 + phytase 1000 FTU/kg + 286.16 ppm CuSO4 ), R9 (R2 + phytase 1000 FTU/kg + 132.70 ppm ZnO + 286.16 ppm CuSO4). The results of this research indicated that the phytase supplementation (1000 FTU/kg), ZnO (132.70 ppm), and CuSO4 (286.16 ppm) in poultry diet 1) improved the body weight and feed conversion, but did not significantly influence the feed consumption, 2) increased serum Zn, and 3) increased the alkalin and phosphatase activity.

Abstract

The objective of this study was to evaluate the effect of supplementation with mineral soap, organic mineral and roasted soyabean on ration fermentability in the rumen of sheep. Thirty two Garut Sheep (initial weight 22.38 ± 3.56 kg) were assigned into a randomized complete block design with 8 treatments. Body weight was used as blocks (4 blocks). The treatments were FO: basal diet + fish oil, CO: basal diet + corn oil, CaFO: basal diet + calcium soap of fish oil, CaCO: basal diet + calcium soap of corn oil, ZnFO: basal diet + zinc soap of fish oil, ZnCO: basal diet + zinc soap of corn oil, RSB: basal diet + roasted soya bean, MM: basal diet + mineral mix (Zn, Cu, Cr, and Se-organic). The experimental diets were offered for 8 weeks. The results showed that ammonia concentrations of sheep fed CO, CaFO, CaCO, and MM were higher than those of sheep fed FO, ZnFO, ZnCO, RSB diets (9.28 v 6.75 mM). Vollatile fatty acid production was not affected by treatments (110.6 ± 7.69 mM). The levels of amonia and VFA in this experiment were suitable for microbial growth. Rumen bacterial population of sheep fed FO was the lowest (P < 0.05). Rumen protozoa population of sheep fed CO, CaFO, ZnFO, ZnCO, and MM were lower (P < 0.05) than those of sheep fed FO, CaCO, and RSB. It is concluded that supplemention of Ca-soap, organic minerals, and roasted soyabeans to sheep ration increased ration fermentability in the rumen. Ammonia and VFA concentrations were suitable for rumen microbial growth. Fat protection (Ca-soap) did not inhibit bacterial growth in the rumen. Key words: mineral soap, fish oil, corn oil, roasted soyabeans, fermentability

Abstract

Plasma concentration of cortisol and hematological profile on broiler chickens can be used as heat stress indicators. This study was conducted to investigate the effect of administration of n-hexane extract of jaloh bark (EHJ) on heat-stressed broiler chicken. Thirty broilers, aged 20 days (strain Cobb), were randomly divided into 5 groups. The first group was external control (tCP) i.e. chickens without heat stress and without EHJ administration. The second group was internal control (CP) representing chickens given heat stress without EHJ administration. The third, fourth, and  fifth groups were chickens given heat stress and EHJ administration at doses 5, 10, and 20 mg/kg BW, respectively symbolized as CP+EHJ5, CP+EHJ10, and CP+EHJ20. The experimental broilers were exposed to heat stress in constant temperature of 33 ± 1oC for 4 hours daily for 5 and 10 days. The EHJ was given 1 hour before temperature in the cage was raised and was given in daily basis.  The level of cortisol in feces were measured from feces collected 1-2 hours before  treatment, 3-4 hours after heat stress exposure, and 2-3 hours after heat stress termination. This research indicated that heat stress at temperature 33 ± 1oC during 2 and 4 hours increased cortisol  excretion in feces (P<0.05) and increased ratio H : L (P<0.10). The EHJ at dose of 10 mg/kg BW relatively gave more protection from heat stress impact on broilers. Key Words: Cortisol, Triiodothyronine, Heat Stress, Salix, Hematology
