Abstract

Livestock is one of the agricultural sectors that plays an important role in providing animal products. Cows are one of the largest meat and dairy producers. The low reproductive efficiency of cattle is the biggest problem in terms of its development. Increasing reproductive efficiency through artificial insemination programs is one way to enhance livestock populations. Reproductive efficiency parameters can be measured through values of Service per Conception (S/C) and Conception Rate (CR). Service per conception and conception rate are related to cows parity. Parity is the number of calf that have been born to a cow. This study aimed to provide information on reproductive efficiency as seen from the value of S/C and CR of cows in different parieties and the factors that influence them. High rates of parity followed by high S/C score and low CR. Each animal has various values of S/C and CR. The normal range for S/C is 1.6-2.0 and 60% in CR. Several factors that affect reproductive efficiency are environment, nutrition, Body Condition Score (BCS), knowledge of farmers, inseminator skills and quality of semen used. The highest service per conception (S/C) value was at parity 5 with aged ± 7 years and the conception rate (CR) was at parity 3 aged ± 5 years.Keywords: should be written in no more than 5 (five) words or phrases.

Abstract

Soft cheese Suspesi is a soft cheese to which biduri leaf extract is added as a coagulant. There is no research on the color, hardness, and content of tannins contained in soft cheese suspesi. The purpose of this research was to analyze and evaluate the hardness, color *L, *a, *b, and tannin content with the addition of biduri leaf extract at levels of 3% and 5% in soft cheese suspesi. This research used a completely randomized design with two treatments with six replications. A1= Biduri leaf extract level 3% (v/v), A2= Biduri leaf extract level 5% (v/v). Data on hardness, color, and tannin content were analyzed by Independent T-Test. The results showed a significant difference (P<0.05) in the hardness, color *L, and tannin content. Color *a and color *b did not show a significant difference (P>0.05). In conclusion, the levels of added biduri leaf extract gave different levels of hardness, color *L, *a, *b, and tannin content in the soft cheese suspesi. The characteristics of the soft cheese suspesi increased in terms of hardness, color *L, *a, *b, and tannin content in line with the level of added biduri leaf extract.

Abstract

Aflatoxin M1 (AFM1) is the main secondary metabolites of aflatoxin B1 (AFB1) framed in the liver and discharged into milk when people and animals polish off AFB1-polluted food. The persist from feed to milk in dairy cows is affected by different dietary and physiological elements, including taking care of regimens, rate of ingestion, rate of absorption, animal health, hepatic biotransformation limit, and real milk production of the animals. AFM1 exposure might cause both intense and constant toxicity. In humans, AFM1 exposure is related with cancer-causing nature, genotoxicity, mutagenicity, and teratogenicity. In dairy animals, persistent openness to AFs can decrease execution, debilitate liver capability, compromise invulnerable capability, and increment sickness susceptibility. AFM1 openness represents a worry for the worldwide populace, especially for babies and youngsters who drink milk in bounteous amounts and thus, are more powerless to unfavorable impacts. The identification and quantification of AFs represents a critical test in food handling confirmation, since even a low AF concentration is hazardous for people and domesticated animals. Consistent human openness through dietary courses has prompted the burden of most extreme cut off points for AFM1 in milk and dairy products, taking into account that this is a gathering of products with exorbitant premium, particularly for babies and youngsters. Likewise, as per different examinations it is additionally very much felt that youthful animals are additionally observed to be more vulnerable to aflatoxin than grown-ups. Consequently; the defilement of cow milk and milk products by AFM1 ought to be perceived as unfortunate for youthful human and animals. Thus, the point of this paper is to review the occurrence of aflatoxin and its adverse results on animals and human health over the time.

Abstract

Egg chips are not yet common in society; therefore it is necessary to require attention for consumer assessments. Consumer ratings of egg chips indicate that consumers can accept egg chip products. The study aims to determine the effect of adding the types and levels of filler on the organoleptic quality of egg chips. Eighty-one eggs were used in the research. The studies were arranged based on a completely randomized design with a 3 x 3 factorial pattern with 3 replications. The first factor consisted of 3 types of fillers; there are tapioca powder, soybean protein isolate, and porang powder. The second factor was the level of filler (%) 3, 6, and 9 respectively. The parameters measured were egg chips' organoleptic quality (aroma, color, texture, and fondness). The results data indicated that the types and levels of fillers had a highly significant effect (P<0.01) on aroma egg chips. There was an interaction between types and levels of filler on the aroma. There was no significant difference (P>0.05) in color, texture, and fondness for egg chips. Adding the type and level of filler material could improve the organoleptic quality of egg chips. The addition of 9% of tapioca powder can increase the aroma of egg chips. Keywords: Egg powder, egg chips, organoleptic

Abstract

Utilization of unconventional materials such as corn tumpi and dragon fruit peel flour as an alternative feed ingredient for ruminants, especially goats. This study aims to examine the effect of providing complete feed containing corn tumpi with dragon fruit peel flour at different levels on consumption and digestibility of goats. This study used 12 local male goats with ages ranging from 1 to 1.5 years which were randomly assigned to metabolic cages. The study used a Randomized Block Design (RBD) method with 3 treatments and 4 groups. The treatments consisted of P1: Complete feed containing 50% corn tumpi, P2: Complete feed containing 45% corn tumpi and 5% dragon fruit peel flour and P3: Complete feed containing 40% corn tumpi and 10% dragon fruit peel flour. The results showed that the treatment of complete feed containing corn tumpi with dragon fruit peel flour at different levels had a significant effect (P<0.05) on dry matter consumption and organic matter consumption. Dry matter consumption ranged from 296.88 – 461.64 g/h/day, and nitrogen consumption was between 265.74 – 407.72 g/h/day. Treatment of complete feed containing corn tumpi with dragon fruit peel flour at different levels had no significant effect (P>0.05) on dry matter digestibility and organic matter digestibility. Dry matter digestibility ranged from 82.75 – 87.50 %, and organic matter digestibility between 84.5 – 88.75 %. It was concluded that based on estimates of dry matter consumption and organic matter consumption, the use of alternative ingredients for corn tumpi with dragon fruit peel flour up to a level of 10% could be used as a complete mix of feed ingredients for ruminants, especially goats.

Abstract

The aim of this research was to examine the feed rumen fermentation in the rumen of goat fed 4 different diets. This study was designed based on the Latin Square Design which consists of 4 diet treatments with 4 replications in each diet treatment. A total of 4 male goats, with relatively the same weight and age, were randomly assigned to an individual metabolic cage fed with 4 diets. The four diets studied were R1: Elephant grass, R2: Mini elephant grass, R3: Panicum maximum grass and R4: Brachiaria decumbens grass. Each diet was added with 20% of rice bran. The result of this experiment indicated that there was no any significant effect of different diets on the pH values, concentrations of VFA (Volatile fatty acids), and Ammonia (NH3) in the rumen of goat. The pH values in the rumen of goat treated with R1, R2, R3, and R4 were 7.17, 7.12, 7.07, and 7.0, respectively. The concentration of ammonia (mM) in the rumen of goat treated with R1, R2, R3, and R4 were 4.6, 3.3. 4.5, and 4.1, respectively. Whereas the level of VFA (mM) in the rumen of goat treated with R1, R2, R3, and R4 were 40.4, 43.6, 48.7, and 49.9, respectively. There was no any significantly difference (p>0.05) in the characteristic of rumen fermentation between the diet treatment. This might be due to the similarity in the nutrient content of those grasses studied. The characteristic of rumen fermentation was in the range of optimal growth of rumen microbes. It is concluded that those of four grasses studied edible, acceptable and contain a good nutrient as a feed resource for goat. The nutrient content of the grasses studied creates a good rumen environment for optimum feed fermentation in the rumen of goat.

Abstract

Intensification of artificial insemination (AI) in Bali cattle is a government program to increase the population and productivity of local cattle. The objective of this study was to examine the reproductive performance of Bali cows through the AI program in Polewali Mandar Regency, West Sulawesi. The study was conducted in two different locations, i.e. in the low lands (<300mASL) including Wonomulyo and Campalagian Districs, and high lands (>300mASL) including Limboro and Bulo Districts. Data collection was carried out on farmers and inseminators profiles, and cow’s reproductive parameters including service per conception (S/C), conception rate (CR), calving rate (CvR), calving interval (CI) and Calf Mortality (CM). These data were calculated and analyzed descriptively. The cows in this study were raised by farmers in small-scale farm, mostly under 5 heads. The cattle breeding through AI program was carried out by inseminators with over 10 years of experience. In the lowlands, S/C values were 1.26-1.17 and CI were 360 to 366.31 days, respectively. Bali cows that were inseminated using Bali bull semen had a CvR of 75.69% which were higher than those using Simmental bull semen (CvR 49.69%;). While in the highlands, Bali cows that were inseminated with Bali bull semen tended to have higher S/C (1.30) and CI (356.95 days) values but had CvR of 61.00% and CR 77.00% which was also higher than that of Simmental bull semen (S/C 1,50; CI 412,86 days; CvR 50.00%; CR 66.67%). The high S/C in the highlands (1.50) is due to location constraints or the distance between the livestock and the inseminator's residence which is quite far, so it takes time to carry out AI services and is one of the factors that can cause the provision of AI services for female cows in heat is not optimal. In the highlands, most of the cattle are grazed in the grazing areas, making it difficult for breeders to detect estrus. In general, Bali cattle produced by AI in the low lands of Polewali Mandar district tended to have better reproductive performance than those in the high lands. The S/C in the low lands (1.26 and 1.17) is lower than that in the high lands (1.3 and 1.5). Keywords: AI, Bali cows, lower land, high land reproductive performance

Abstract

Layer eggs are low cost and highly nutritious, but they are perishable. Therefore, it is important applying preservation for prolong its shelf life. Preservation by using natural agent such as belimbing wuluh (Averrhoa bilimbi L) leaf (BWL) extract for food safety and consumer health is ratioable. This study aimed to evaluate the immersion of layer eggs in an aqueous extract of BWL on the pH value and total microbial eggs. The treatments employed were eggs without soaking (P0), eggs soaked in aquadest (P1), eggs soaked in solution of BWL leaf extract (SBWLE) 15% (P2), eggs soaked in SBWLE 30% (P3), and eggs soaked in SBWLE 45% (P4). Soaking was carried out for 24 hours with the proportion of egg: water SBWLE was 1:13. The extraction process was carried out by boiling the BWL for 10 minutes at a temperature of 85 ºC. The boiled water is filtered and the results were used for treatment. The data were analyzed by ANOVA and he significant effect (P <0.05) of treatments were tested by a post hoc Duncan's Multiple Range Test (DMRT). The results showed that eggs soaked in SBWLE had lower pH and total microbes than eggs without soaking and eggs soaked in aquadest. The higher concentration of SBWLE, the decreasing pH and total microbes in eggs. The conclusion was that the use of SBWLE 15-45% (w/v) was able to suppress egg microbial growth and prevent an increase in egg pH. Keywords: Averhoa bilimbi, egg quality, microbes, pH

Abstract

Coastal areas are potential land for the cultivation of feed crops to support the availability of livestock forage. Indigofera zollingerianaplants have a high tolerance to salinity stress. Gamma irradiation technology, which can change the genetic structure of plants, is expected to increase plant tolerance. This study was conducted to determine the morphological response of Indigofera zollingeriana Mutant, two plants irradiated with gamma rays in coastal areas. This study used a complete randomized design (CRD) method with ten treatments and six replications. The treatments consisted of P0 (control/without irradiation); P1 (Indigofera M2 50 Gy); P2 (Indigofera M2 100 Gy); P3 (Indigofera M2 150 Gy); P4 (Indigofera M2 200 Gy); P5 (without irradiation + salinity stress); P6 (Indigofera M2 50 Gy + salinity stress); P7 (Indigofera M2 100 Gy + salinity stress); P8 (Indigofera M2 150 Gy + salinity stress); and P9 (Indigofera M2 200 Gy + salinity stress). The analysis of variance showed that different doses of gamma irradiation and salinity stress had a significant effect (P<0.05) on stem diameter and number of flowers of Indigofera zollingeriana plants. Irradiation dose of 150 Gy with salinity stress during seedling can grow higher leaves when planted in coastal areas. Keywords: Salinity Stress, Indigofera zollingeriana, Gamma Irradiation

Abstract

Coastal areas have great potential to be developed. One of the good sectors developed in coastal areas is livestock, but the obstacle to the development of livestock in coastal areas is saline land conditions that can affect the process of plant growth. Indigofera zollingeriana is a plant that is tolerant to various types of environmental stress, one of which is salinity stress. Induced mutation is currently the most effective breeding method for plant genetic improvement. One example of induced mutation treatment is gamma irradiation. This study used a complete randomized design method with ten treatments and six replicates. The treatments consisted of P0 (Control/Without irradiation); P1 (50 Gy gamma irradiation); P2 (100 Gy gamma irradiation); P3 (150 Gy gamma irradiation); P4 (200 Gy gamma irradiation); P5 (Irradiation was given salinity stress); P6 (50 Gy gamma irradiation and salinity stress); P7 (100 Gy gamma irradiation and salinity stress); P8 (150 Gy gamma irradiation and salinity stress); and P9 (200 Gy gamma irradiation and salinity stress). The results of the analysis of variance showed that the treatment of gamma irradiation dose and salinity stress had a significant effect (P<0.05) on the total weight, leaf weight, and leaf production of Indigofera but no significant effect (P>0.05) on stem weight and production. Keywords: Salinity stress, Indigofera zollingeriana, gamma irradiation
