Abstract

The objective of the research was to determine the effect of cassava leaf meal addition in commercial diets on weight of gizzard, heart and liver of broiler strains CP 707 and find out the addition level which produced the highest weight of gizzard, heart and liver of broilers. The experiment used Completely Randomized Design with 5 dietary treatments, namely 100% commercial ration (R0), 96% commercial diet plus 4% cassava leaf meal (R1), 92% commercial diet plus 8% cassava leaf meal (R2), 88% commercial diet plus 12% cassava leaf meal (R3), 84% commercial diet plus 16% cassava leaf meal (R4). Each treatment was repeated 5 times. Variables measured were the weight of gizzard, heart and liver. Data were analyzed with ANOVA and followed by Duncan's Multiple Range Test. The addition of cassava leaf meal in commercial ration influenced weight of gizzard and heart, but did not affect liver weight. The highest weight of gizzard and heart obtained from broilers consumed 84% commercial diet with the addition of cassava leaf meal as much as 16%.

Abstract

The objective of the study was to determine the effect of skim milk and Tris yolkextender on the viability bovine spermatozoa at 5 ºC. This study used Simmental bull semen. The design used was Randomized Design Group (RAK) with 5 treatments and 5 groups of ejaculate. The treatments were: P0 = skim milk 100% without Tris yolk extender; P1 = 95% skim milk + 5% Tris yolk extender, P2 = 90% skim milk + Tris yolk extender 10%, P3 = skim milk 85% + Tris yolk extender 15%, P4 = skim milk 80% + Tris yolk extender 20%. The observed variables were the percentage of live spermatozoa and the motility of spermatozoa after storage for 2 days at 5ºC. Skim milk with Tris yolk extender affect the viability and motility of spermatozoa stored at 5ºC (P<0.01). Provision of extender up to 15% gave the best results and suppressed the decline in the viability of spermatozoa storaged for 2 days at 5ºC.Key words: skim milk, spermatozoa, Tris yolk extender, viability

Abstract

The purpose of this study was to know the effect of vitamin E addition in glucose phosphate diluent on the survival of sheep spermatozoa at 5 °C. The xperiment used 3 rams. The design used was Completely Randomized Design (CRD) with 5 treatments and 4 replicates, each replicate with 3 ejaculate cement of sheep. The treatments were the dose of Vitamin E with E0 = 0 μg/ml, E1 = 1 μg/ml, E2 = 4 μg/ml, E3 = 7 μg/ml, and E4 = 10 μg/ml. Variables measured were motility, live spermatozoa and plasma membrane integrity. Data were analyzed by using analysis of variance according to Steel and Torrie (1981). The result showed that treatment of vitamin E with a dose of 1 μg/ml - 10 μg/ml l had no significant effect on motility, percentage live spermatozoa and membrane integrity of sheep spermatozoa on day two (P> 0.05).

Abstract

The study was conducted to investigate the effect of kalium iodide (KI) administration to tyroid gland weight, and body weight gain, and rectal temperature of postweaning PE goat. Nine postweaning PE goat alloted into three treatments : P0 (control), P1 (0.1 ml KI), and P2 (0.2 ml KI), KI administered twice a week. Variables observed were tyroid gland weight, final body weight and rectal temperature. Data analized by ANOVA using GLM procedure of SPSS. The weight of tyroid gland of P0, P1, P2 were 2.0988 mg, 1,5650 mg, and 2.0088 mg respectively. The treatment  affected (P<0.05) bodyweight gain  without change of rectal temperature (P>0.05). Inconclusion, 0.1 ml KI adminitration twice a week increased body weight gain, lighter tyroid gland weight without effect to rectal temperature.

Abstract

This research aimed to see how the impact of time to replace BR 1 with BR 2 ration to slaughtering weight, carcass weight, and abdominal fats of broiler. This research was an experimental method using Complete Randomized Design (CRD) with five treatments and five replication. These treatment consisted of P1: giving BR 1 (1 to 42 days old), P2: giving BR 2 (1 to 42 days old), P3: giving BR 1 (1 to 7 days old), and giving BR 2 (8 to 42 days-old), P4: giving BR 1 (1 to 14 days-old) and giving BR 2 (15 to 42 days-old), P5: giving BR 1 (1 to 21 days-old) and giving BR 2 (22 to 42 days-old). The observed variables were slaughtering weight, carcass weight, and abdominal fats of the broiler. The collected data were analyzed by ANOVA and Duncan's test. The results showed that various feeding timing techniques from starter feed (BR1) to grower feed (BR2) did not make a significant difference (p>0.05) in broiler slaughter weight, carcass weight, and abdominal fat. Each of these weights is in the range of 2617.86 – 2754.24 g/head; 2010.51 – 2076.69 g/head or 75.00 – 76.80%; and 41.70 – 44.40 g/head. It can be concluded that all techniques when changing feed types from BR1 to BR2 can be carried out by breeders, however, the economic value of these techniques must be considered because the two types of feed have different prices.

Abstract

The purpose of this research was to influence of substistution flour Indigofera zollingeriana in Rations on performance broiler and to know the percent of the substistration of Indigofera zollingeriana flour that is able to improve performance in the most optimal broiler. This research was conducted in Cihaliwung, RT 01 RW 10, Kertamulya Village, Padalarang District, West Bandung District during 42 days start from January 27 until March 08, 2021. The method used in this research was experimental method with using Complete Randomized Design (CRD), five treatments namely R0 (commercial ration 100%), R1 (commercial ration 90% + 10% Indigofera zollingeriana flour), R2 (commercial ration 85% +15% Indigofera zollingeriana flour), R3 (commercial ration 80% + 20% Indigofera zollingeriana flour), R4 (commercial ration 75% + 25% Indigofera zollingeriana flour) with four replication, each replication consisted of five broilers. The observed changes are ration consumption, daily weight gain, and ration conversion. The collected data was analyzed by ANOVA and Duncan's test. Based on the results and discussion, it can be concluded that the substitution of flour Indigofera zollingeriana until 25% in the ration had no significant effect on ration consumption, daily body weight gain and ration conversion.

Abstract

The purpose of this study was to investigate the closed-house cage density near the outlet that affected the production of carcass, non-carcass, and abdominal fat of finisher phase broilers and to ascertain the number of closed-house cage density that could produce the ideal amount of carcass, non-carcass, and low abdominal fat. The experiment employed a completely randomized design with four treatments: T0 (10 birds per square meter), T1 (12 birds per square meter), T2 (14 birds per square meter), and T3 (16 birds per square meter). It was replicated five times using different numbers of broilers in each replication depending on the cage density. The observed variables were live weight, carcass weight, percentage of carcass, percentage of non-carcass, and percentage of abdominal fat. Data were subjected to analysis of variance and further tested with Duncan's multiple-range test. The study was carried out for 35 days at Farm H. Noto Miharjo in Adiwarno Village, Buayan District, Kebumen Regency, Central Java. The research results showed that the live weight, carcass weight, and carcass percentage were significantly impacted by closed-house cage density at the area near the outlet, although non-carcass percentage and abdominal fat were not significantly impacted. A closed house cage density of 12 birds per square meter at the area near the outlet can provide an optimal production of carcass, non-carcass, and abdominal fat.
