Abstract

This study aims to determine the determinants of size and shape of Simbal and Brahman Cross cattle in the West Pamenang sub-district, Merangin district. The method of this study was a survey with a purposive sampling technique. Sampling criteria included: Sample of each breeds consisted of 60 Simbal and 60 Brahman Cross cattle aged 1-2 years. Data observed included: body length, shoulder height, chest circumference, inside chest, chest width, canon circumference, hip height, body weight, and body weight gain. The differences in body measurements between Simbal and Brahman Cross cattle analyzed by T-test. Identification of the determinants of size and shape of Simbal and Brahman Cross cattle were analyzed using Main Component Analysis method. The results of this study were body weight, body weight gain, and body measurements of Simbal cattle were significantly different (P <0.05) higher than Brahman Cross cattle, both male and female. Simbal cattle and male Brahman Cross cattle were significantly different (P <0.05) higher than females. The conclusion shows that body weight, body weight gain, and body measurements of Simbal cattle are higher than Brahman Cross cattle. Male body weight gain was higher than females in both Simbal and Brahman Cross cattle. The determining factor for the body size of Simbal and Brahman Cross cattle is chest circumference, while the determining factor for body shape of Simbal cattle is the height of shoulders, while Brahman Cross is body length. The highest correlation between body measurements and body weight in Simbal and Brahman Cross cattle, both male and femal is chest circumference (LD).

Abstract

A research group of Animal Science Faculty of Brawijaya University introduced and implemented Frozen sexed semen Artificial Insemination to 120 beef cattle farmers in Palang Village, Tuban Regency, East Java, from 2017 to 2019. The result of the program reported that the success rate of the technology is quite high, with the birth rate of male claves up to 80%. However, farmers’ adoption rate of the technology was relatively low. This research aims to evaluate factors that affected the adoption rate including the technology, characteristics of respondents, and the extension agents. Primary data were collected through a census of 120 farmers involved in the program and in-depth interviews with stakeholders. Secondary data were collected through related documents including reports of the programs, Statistics, and other related documents. This research utilized Quantitative and qualitative analyses. Data of the study indicated that respondents have neutral perceptions of the Frozen Semen Sexing Artificial Insemination. Although male calves relatively have a higher price, more than 50% of respondents did not expect specific sexing for the calves. In-depth interview data revealed that the success of the Artificial insemination technology is more valuable for the farmers rather than the sexing. Characteristics of respondents and the extension agents played significant roles in the adoption rate of the Frozen Sexed Semen Artificial Insemination technology adoption in Palang Village, Tuban Regency, East Java.

Abstract

Indonesia is an island country consisting of thousands of islands. The population of Indo-nesian people is increasing annually, making the need for food also increases, especially food originated from the livestock sector, namely beef. The difference in consumer centers' location with cattle production centers causes the need for transportation that can transport cattle from one island to another. Camara Nusantara is the first livestock vessel in Indonesia that started in 2015. Camara Nusantara took the ship's design from Australi-an livestock vessels, but there have not been any studies on the facilities and design of the Camara Nusantara ship. This research took place in Camara Nusantara ship for 5 days from Kupang, East Nusa Tenggara to Tanjung Priuk, Jakarta.  The observation was done by noting and observing all facilities used from the livestock loading process in the port of Tenau to Tanjung Priok port. The results showed that there were still many shortcomings in the facilities used, so the need for improvement is done to avoid any stress generated during the transportation process that can cause further loss.

Abstract

The study was aimed to examine the production of volatile fatty acids (VFA) and methane (CH4) in rations based on protein-energy synchronization index (PES) using different meals protein sources (MPS). The study was conducted experimentally with in vitro techniques. The factorial completely randomized design (CRD) was used to examine six types of treatment rations originating from a combination of 3 PES index and two types of MPS, each repeated four times so that there were a total of 24 experimental units. The results showed that the interaction of the SPE index had no significant effect on the production of partial VFA, but had a significant effect on the acetate: propionate (A: P) ratio and CH4 production. The analysis of honestly significant different (HSD) results showed that the lowest A: P ratio and CH4 were found in R1. The orthogonal test shows that coconut and soybean meal had a quadratic effect on the A: P ratio and CH4. It concluded that the best PES index to optimize VFA and minimize CH4 production was at the index 0.6-0.61 with soybean meal as protein source supplementation.

Abstract

The residue originated from antibiotics and hormones had been thought to carry out adverse effects for the human who consume meat processed from the broilers treated by antibiotic feed additive. For this reason, using an alternative additive such as probiotic might produce healthier meat. The objective of the recent study was to evaluate administering different levels of probiotic yakult + tape yeast (YTy) into the mixing of rice bran + corn bran (RCB) to replace 30% of the commercial diet to carcass yield and abdominal fat of broilers. As many as 100 broiler chicks, Cobb strain, were reared up to 5 weeks in this study. The study was designed into a Completely Randomized Design with subsampling consisted of 5 treatments, 4 replications, and 2 sub samples. Broiler commercial diet with the market code of CP 511 Hi-provite manufactured by PT Charoen Pokphand was used for a positive control diet (P0+). The RCB feeds were mixed with 0, 10, 20, and 30 ml/kg of probiotic YTy then being used to replace 30% of the commercial diet to build experimental diets P0-, P1, P2, and P3, respectively. The results of the recent study indicated that administering 10‒30 ml/kg of probiotic YTy highly significantly (P<0.01) increased the weights of the whole carcass and carcass parts. The percentages of whole carcasses among P1, P2, and P3, however, were not statistically different. The percentage of the breast significantly (P<0.05) increased while the percentage of the back significantly (P<0.05) decreased. Although statistically not significant differences, the abdominal fat percentage tended to decline. In conclusion, administering a probiotic YTy in the diet increased the percentage of the whole carcass and tended to reduce the abdominal fat of the broiler.

Abstract

This study aimed to evaluate feed protein utilization and nitrogen emission of young and mature Kejobong goats fed different concentrations of concentrate and forage. Sixteen heads of male Kejobong goats consisted of eight heads young goats (5 months old) and eight heads mature goats (9 months old) with initial body weight (BW) of 14 ± 1.46 kg, and 22.3 ± 1.99 kg, respectively were arranged in a nested design. All goats were fed with two different rations of concentrate and forage (C30 = 30% concentrate: 70% forage and C70 = 70% concentrate: 30% forage). The data were analyzed using ANOVA procedure. This study showed that the average daily gain (ADG) did not differ (p>0.05) in both ages, but it differed (p<0.05) in concentrate levels. The ADG of goats fed C70 was significantly higher (p<0.05) than those of goats fed C30 in both ages. The digestible crude protein (DCP) of young and mature goats was similar (p>0.05), while there was a significantly difference (p<0.05) between the treatments. There were no effects of different ages of goats and concentrate levels on feed conversion ratio (FCR) (p>0.05). The different ages of goats and concentrate levels affected N retention (g/day) and total N2O emission (g/day). It was concluded that ADG, DCP and FCR did not differ in mature and young Kejobong goats, while young goats had less N2O emissions than mature goats. Goats fed 70% of concentrate improved their ADG, DCP, N retention (g/day) and produced less N2O emission.

Abstract

COVID-19 has highlighted the need for robust cattle supply chains using local feed resources. Higher Income Over Food Costs (IOFC) are usually achieved when live weight gains are high and the cost of the ingredients are low. There is a need to formulate rations with high metabolisable energy (ME) and crude protein (CP) to achieve the high live weight gain. Rations can be formulated locally by farmer co-operatives, entrepreneurs and local commercial enterprises to take advantage of cheaper prices for local ingredients. To do this, rations need to be altered quickly to take advantage of local fluctuations in prices and availability of ingredients. A recent ACIAR funded project has developed a least cost ration (ACIAR LCR) system to formulate rations to meet minimum ME and CP contents for beef cattle using locally available ingredients. The use of cassava and its various products in combination with protein sources, such as tree legumes and high protein by-products, have markedly improved IOFC.

Abstract

Ovarian hypofunction is one of the reproductive disorders that occur due to a decrease in ovarian function that causes animals to not experience heat. The purpose of this study was to determine the effect of GnRH antagonist hormone interventions on ovarian hypofunction model rats by looking at the expression of alpha ERs (ERs α) and the profile of folliculogenesis in the ovaries. This study used two groups of female Wistar strain rats, aged 8-10 weeks, bodyweight 150-180 grams and each group contained 10 animals. Intervention gave control group, without cetrorelix acetate intervention (placebo aqua dest sterile), treatment group with the induction of cetrorelix acetate 0.0135 mg/kg BW for 17 days. Observation of α ERs expression in the ovary was analyzed by immunohistochemical methods, and data were analyzed using T-Test analysis (α <0.05). Meanwhile, the folliculogenesis profile was analyzed by hematoxylin-eosin (HE) staining, then analyzed descriptively. The results of this study indicate that the treatment group given the intervention cetrorelix acetate dose 0.0135 mg/kg BW showed significantly different results compared to the control group. In the treatment group, the ERs α expression decreased by 82.7% compared to the control group and in the folliculogenesis profile,  there was a decrease in follicular development from pre-antral follicles to antral follicles. Cetrorelix acetate interventions can have an effect on the inhibition of folliculogenesis and estrogen binding with ERs that cause anoestrous.

Abstract

The broiler is one of the potential husbandry commodities to be developed, but its development faces various risks, particularly production risk. This is indicated by fluctuating mortality of broiler in each period. This research aimed to analyze some production factors determining production and production risk of broiler production activity in the Regency of North Minahasa, Province of North Sulawesi.  In addition, the research's site was purposively determined, such as six villages representing three districts (District of Dimembe, Kauditan, and Kalawat) having the largest population of breeders under partnership program in the Regency of North Minahasa. From each village, then, breeders were selected by sampling method, comprising 27 breeders of Village of Dimembe, 18 breeders of Village of Matungkas, 19 breeders of Village of Kauditan Satu, 16 breeders of Village of Kauditan Dua, 13 breeders of Village of Kolongan and 10 breeders of Village of Suwaan. The sample of breeders was 100 respondents of the breeder. Further, data collected by survey and analyzed employing Just and Pope Analysis to know some production impacts against production and production risk of broiler. In conclusion, the research shows that the variable of a total of feed, heater, ammotrol, rice husk, and a total of labors could improve broiler production, and variable of Day Old Chick (DOC) could decrease broiler production. Variable of a total of feed, vitamin, rice husk, and a total of labors could decrease production risk of broiler, but a total of a day of chicks could increase production risk of broiler.

Abstract

The aim of this research was to study the in vitro ruminal fermentability of supplementation of Gliricidia sepium, Moringa oleifera, Lamk (MOL), Ceiba pentandra and Paraserianthes falcataria leaf meal in concentrate feed to be tested on sheep. This research with the experimental methods was arranged in Randomized Block Design (RBD) with 6 treatments and 3 groups. The treatment feed tested consisted of concentrate without leaves and concentrate with leaf meal supplementation. Crude protein content (CP) concentrates were prepared 16%, 18% and 20%. Supplementation uses a mixture of Gliricidia sepium, MOL, Ceiba pentandra and Paraserianthes falcataria leaf meal in concentrate feed (1: 1: 1: 1) as much as 10%, 20% and 30%. The measured variables were  degradation of dry matter (DDM) and degradation of organic matter (DOM), gas production rate, microbial biomass and NH3 concentration. The use of mixed leaf meal in concentrate feed resulted in in vitro DDM as well as concentrate feed without leaf meal supplementation. Supplementation of leaf meal in concentrate feed as much as 30% with CP 20% resulted in a decrease in the value of fermentability. The supplementation of leaf meal in concentrate feed as much as 20% in concentrate feed with CP 18% produced the best fermentability value. Suggested for in-vivo trials on sheep using 18% protein concentrate feed by utilizing Gliricidia sepium, MOL, Ceiba pentandra and Paraserianthes falcataria leaf meal in concentrate feed as cheap protein sources.
