Abstract

This study aimed to evaluate the effect of Indigofera leaf meal (ILM) and to measure the optimum composition of the addition of ILM in the diet on the performance of layer roosters. The study conducted experiments on 100-layer roosters of the Cobb strain. The experimental design used a completely randomized design (CRD) with four treatments and five replications, each replication with five chicks. The treatments were R0 (100% commercial feed or non-ILM); R1 (90% commercial feed + 10% ILM); R2 (80% commercial feed + 20% ILM); and R3 (70% commercial feed + 30% ILM). The data were processed by analysis of variance (ANOVA one way) and further tested by Duncan's multiple range test (DMRT). The results showed that the addition of 10% ILM in the diet could increase (P<0.05) feed consumption and average daily gain and could provide a lower feed conversion and feed cost per gain value (P<0.05) than R0. Treatment R2 and R3 did not have a better impact than treatment R0 (P>0,05). It can conclude that adding 10% Indigofera leaf meal to the diet can have a good effect on the performance of layer roosters.Keywords: indigofera leaf meal, layer rooster, performance

Abstract

This study aimed to evaluate the effect of sorghum-Indigofera forage-based feed on the pre-mating performance of Garut ewes. A total of 28 Garut ewes was divided into two groups of treatment so that each treatment consisted of 14 heads. The treatment of field grass (FG) as a control and the feed composition in the formula of 50% sorghum forage silage + 40% Indigofera hay + 10% rice bran (SI). The animals were distributed under a completely randomized design, and the data were analyzed using a t-test. The results showed that the dry matter intake (DMI) and nutrient digestibility values of FG were higher (p<0.05) than SI. However, the impact on body weight gain, blood urea nitrogen (BUN) and blood cholesterol level did not differ (p>0.05). The average pre-mating bodyweight of Garut ewes for all treatments was the same number relatively, were 35 kg/head. BUN and blood cholesterol levels in the FG and SI treatments were 36.18±3.47 vs 35.27±4.23, and 66.13±5.56 vs 69.25±3.95 mg/dl, respectively. It can be concluded that SI feed had higher efficiency values and better readiness for the reproductive phase. Therefore, SI feed can be used as a substitute for field grass for the reproductive stage of Garut ewes.

Abstract

Beef meatballs using tapioca flour only contain a small amount of protein, fat and fiber in them. The nutrition is very low, only around 0.1% of the daily recommendation. Therefore, there is a need for healthier alternative flour, one of which is oat flour. This research is a diversification of healthy meatball products made from oat flour which contains better nutrition than tapioca flour. The method used was an experimental study with a completely randomized design pattern of three treatments (substitution of tapioca flour with oat flour at 0%; 50% and 100%) which was repeated seven times. The variables observed were chemical quality (air, protein, fat, carbohydrates), physical quality (pH and cooking loss) and organoleptic properties (color, aroma, texture and taste). Data analysis used analysis of variance (ANOVA). If there is a significant difference between treatments, Duncan's further test is carried out. The results showed that the amount of oat flour had a significant effect (P<0.05) on the pH of the meatballs. The amount of oat flour linearly (P<0.05) reduced the level of meatball cooking loss. The organoleptic properties of meatballs with 50% oat flour are more similar to meatballs using 100% oat flour, and have slightly the same level of preference. It can be concluded that oat flour can be used as a substitute for tapioca flour to improve the physical and organoleptic quality of beef balls. Meanwhile, the ideal oat flour substitution rate is as much as 50%.

Abstract

One of the strategies employed to augment the population of Pasundan cattle is the implementation of an Artificial Insemination (AI) program. The efficacy of the insemination process is significantly contingent upon the quality of the spermatozoa following the thawing of frozen semen. The selection of an appropriate frozen semen diluent can enhance the efficacy of the AI process. The objective of this study was to analyze the impact of egg yolk tris and skim milk diluent on the quality of spermatozoa derived from frozen semen of Pasundan cattle following thawing. Additionally, the study aimed to assess the extent of variation in spermatozoa quality produced after thawing, based on the type of frozen semen diluent utilized. The study was conducted using a completely randomized design (CRD). A total of 30 frozen semen samples of Pasundan cattle were randomly assigned to two treatment groups, with 15 replicates in each group. The two treatments were a frozen semen dilution using egg yolk tris and skim milk. The parameters observed included motility, viability, and intact plasma membrane (IPM) of spermatozoa following the thawing of frozen semen. Moreover, to ascertain the extent of the discrepancy between the two treatments, the data were subjected to a t-test. The findings indicated that the use of yellow tris as a diluent resulted in a higher spermatozoa motility rate (p<0.05) compared to skim milk as a diluent (47.73 ± 0.67 vs. 14.16 ± 1.55).  Furthermore, the two types of diluents did not have a significant effect on post-thawing spermatozoa viability (p>0.05). In contrast, the variable of intact plasma membrane (IPM) demonstrated a higher number for the skim milk diluent (p<0.05) than the egg yolk tris (79.71 ± 1.30 vs. 75.59 ± 1.38). The motility of post-thaw spermatozoa is the factor that plays the most pivotal role in the effectiveness of artificial insemination. It can be concluded that egg yolk tris is a superior type of frozen semen diluent for Pasundan cattle, as evidenced by its ability to produce a greater of spermatozoa motility than skim milk diluent.

Abstract

Pasundan cattle are West Java's indigenous Genetic Resources, and the proper frozen semen thawing technique is necessary for successful artificial insemination (AI) to increase the cattle population. This study aimed to evaluate the quality of spermatozoa of Pasundan cattle frozen semen post-thawing at various temperatures and thawing duration. A total of 24 frozen semen samples were thawed with two treatment factors: temperature (27 and 37°C) and thawing duration (15, 20, 25, and 30 seconds). The observed variables included motility, viability, and plasma membrane integrity. Data were analyzed using the General Linear Model (GLM) for these variables, followed by the Tukey test for multiple comparisons. The results showed no interaction between temperature and thawing time on the observed variables. There was no significant difference (p>0.05) in sperm motility between treatments, with values ​​between 45.30±0.78 and 52.57±3.59%. Furthermore, the sperm viability rate was significantly different (p<0.05) due to temperature and thawing time. Sperm viability was higher in the 37°C thawing group for 15 seconds. In contrast to the integrity of the sperm plasma membrane, the 27°C temperature treatment group had a higher rate than the 37°C treatment group. It can be concluded that thawing frozen semen of Pasundan cattle at 27 or 37°C with a duration of 15-30 seconds produces normal spermatozoa quality, and a temperature of 37°C for 30 seconds is recommended for the thawing process. These findings contribute to optimizing thawing protocols in artificial insemination practices, enhancing the reproductive success of Pasundan cattle.

Abstract

Penelitian ini bertujuan untuk mengamati karakteristik kuantitatif Domba Garut dalam sistem pemeliharaan yang berbeda berdasarkan usia dan jenis kelamin. Metode observasi dilakukan untuk memperoleh data empiris karakteristik kuantitatif domba Garut yang dipelihara secara intensif dan semi intensif. Sampel penelitian ditentukan dalam dua tahap sampling yaitu berdasarkan sistem pemeliharaan (intensif dan semi intensif) dan umur domba (lepas sapih atau 3-4 bulan, domba muda berumur 8 bulan, dan domba dewasa umur >12 bulan). Umur domba ditentukan berdasarkan kondisi gigi permanen, dan setiap unit yang diamati berlokasi di wilayah Kecamatan Kertajati Kabupaten Majalengka. Variabel yang diamati meliputi tinggi bahu, panjang tubuh, lingkar dada, lebar dada, tinggi pinggul, dan berat badan. Data yang diperoleh dianalisis menggunakan uji-t. Hasil penelitian menunjukkan bahwa domba Garut betina yang dipelihara secara intensif pada setiap fase usia memiliki sifat kuantitatif yang lebih baik, dan beberapa variabel menunjukkan perbedaan yang signifikan (p<0,05) dibandingkan dengan semi intensif. Berbeda dengan domba Garut jantan, pada fase usia penyapihan, sifat kuantitatif cenderung lebih tinggi pada domba yang dipelihara secara semi intensif, bahkan variabel panjang tubuh dan tinggi pinggul secara signifikan lebih tinggi (p<0,05) daripada yang dipelihara secara intensif. Namun, pada usia 8 dan >12 bulan, Karakteristik kuantitatif keseluruhan domba jantan Garut yang dipelihara secara intensif cenderung lebih baik daripada sistem pemeliharaan semi-intensif. Dapat disimpulkan bahwa karakteristik kuantitatif domba Garut dipengaruhi oleh sistem pemeliharaan, dan sistem pemeliharaan intensif cenderung memiliki karakteristik kuantitatif yang lebih baik daripada sistem pemeliharaan semi intensif.

Abstract

This study aims to analyse the physical quality and protein content of broiler chicken meat resulting from the substitution of fish meal and soybean meal with Indigofera (Indigofera zollingeriana) leaf meal  (ILM) in the ration and to obtain the ideal substitution level of fish meal and soybean meal with Indigofera leaf meal in the ration to produce the best physical quality and protein content of broiler chicken meat. The study was conducted experimentally on 100 broiler chickens for 35 days using a Completely Randomized Design (CRD). The treatments given were the substitution of fish meal and soybean meal in the ration with five levels of ILM, namely: 0% (P0 as control), 25% (P1), 30% (P2), 35% (P3), and 40% (P4), each treatment was repeated 4 times. The variables observed included the degree of acidity (pH), cooking loss, water-holding capacity (WHC), and meat protein content. The data obtained were analyzed using variance analysis (ANOVA) and further tested using Duncan's Multiple Range Test (DMRT). The results showed that substituting fish meal and soybean meal in the ration did not significantly affect (p>0.05) the pH value and cooking loss of broiler chicken meat. In contrast to the variable of water holding capacity, the ILM substitution of 25% produced the highest number (p<0.05) compared to the control and other substitution levels, which was 37.38%. The lowest meat water holding capacity occurred at % ILM substitution level of 40% (19.64%). Furthermore, the crude protein content of the meat showed an increasing trend along with the ILM substitution level. The highest crude protein content was obtained at the ILM substitution level of 35%, significantly different (p<0.05) from the control treatment and the ILM substitution level of 25%. Substituting fish and soybean meal with ILM increased the crude protein content and physical properties except for broiler chicken meat's pH and cooking loss value.

Abstract

This research was carried out from July 30 to September 2 2024. This research aims to test the quality of laying chicken feses compost based on variations in probiotic dosage and composting time. The variations in probiotic doses used were 0%, 5%, 10%, and 15%, with composting times of 14, 21, and 28 days. This research used a Completely Randomized Design (CRD) method with a 4 x 3 factorial pattern, namely four levels of probiotic dosage and three levels of composting time, with each treatment combination repeated three times. The data obtained were analyzed using the General Linear Model and continued with the Tukey test to determine differences between treatments at the 5% level. The parameters measured include nitrogen (N), phosphorus (P), potassium (K), and composting temperature. The results showed that the addition of probiotics and composting time had a significant effect on compost quality (P<0.05). The interaction between probiotic dose and composting time did not have a significant impact. A 10% probiotic dose produced the highest nitrogen (1.33%) and phosphorus (0.37%) content on day 28, which meets compost quality standards based on the Indonesian National Standard (SNI). The highest potassium content (2.17%) was found at a 5% probiotic dose on day 28. Composting temperature reached its peak on day 21, with the highest temperature in the 5% probiotic treatment (36°C). The conclusion from this research is that a 10% probiotic dose with a composting time of 28 days is an ideal combination to produce high quality laying hen feses compost.

Abstract

This study aimed to determine the effect of sorghum-indigofera (SI) mixed feed and pregnant mare serum gonadotropin (PMSG) hormone stimulation on ewe’s reproductive performance and Garut lamb’s pre-weaning growth. Twenty-eight multiparous Garut ewes were included into four treatment groups (2 ´ 2) with a factorial-Completely Randomized Design (CRD). The first factors were the types of feed local forage (LF) and SI, while the second factor was PMSG hormone stimulations (with and without PMSG stimulation). Synchronized estrous used twice injections with PGF2α, 11 days apart, and 500 IU PMSG was adminstrated at the second PGF2α injection intramuscularly. The observed variables included ewes' performance after parturition and post-natal lamb's growth. The obtained data were analyzed by multivarians of analysis (MANOVA) with α = 0.05 and continued with Tukey's Test. The result showed that feeding ewes with SI without PMSG stimulation resulted in the highest number of pregnancies, litter size, and lactation compared to other treatments. Feed type and PMSG stimulation factors has no any interaction effect (p > 0.05) on birth weight, weaning weight, and milk production. However, birth weight and milk production were affected (p < 0.05) by the feed, while weaning weight was affected (p < 0.05) by the PMSG stimulation. The fastest lamb growth rate was found in the groups of ewes fed by SI without PMSG stimulation (120 g/head/day). It can be concluded that SI could improve the ewe’s reproductive performance and the post-natal growth of Garut lambs. Meanwhile, the PMSG hormone could beneficially with sorghum-indigofera mixed feed.
