2024-03-13T15:48:42+00:00

This study aimed to assess the impact of incorporating African leaf juice into drinking water on the blood profile. A completely randomized design was used with 120 laying quail divided into three treatments and five replicates. The treatments included a control group (without African leaf juice) and two groups with African leaf juice added to their drinking water at 3 ml/bird/day doses and 6 ml/bird/day. The results showed that adding African leaf juice 3 ml and 6 ml/bird/day in drinking water decreased haemoglobin. Adding 3 and 6 ml/bird/day of African leaf juice in drinking water did not affect leukocyte differentiation. It was concluded that adding 3 ml/bird/day of African leaf juice could be used in quail drinking water.

Estimating heritability values can be used to implement selection programs and evaluate more targeted breeding programs in Bali cattle. This study aims to estimate the heritability value of birth weight, weaning weight and yearling weight of Bali cattle at Balai Pembibitan Ternak Unggul dan Hijauan Pakan Ternak (BPTU-HPT) Denpasar Bali. The research material used is the recording data of 500 Bali cows originating from 24 males (sire)with 500 Bali cows (dam) that produce offspring of as many as 500 calves. The data was secondary data, obtained by taking records of body weight data, including birth weight, weaning weight, and yearling weight, along with pedigree data of Bali cattle raised from 2017 to 2021 at BPTU-HPT Denpasar. Estimating the heritability value is done using a one-way unbalanced layout model. The results showed that the heritability values of birth, weaning, and yearling weights were 0.25±0.09, 0.23±0.08, and 0.16±0.07, respectively. Based on these results, it can be concluded that the heritability value of birth weight, weaning weight and yearling weight in BPTU-HPT Denpasar Bali is included in the moderate category so that it can be used as a selection guide to increase the productivity of Bali cattle as local Indonesian cattle.

This study aims to determine the effect of the thawing technique on the quality of Boer goat semen with tris aminomethane diluent supplemented with quercetin antioxidants. The materials used in this research are the semen of a Boer goat, which was collected with an artificial vagina. This study used experimental laboratory methods. The design pattern used is a Factorial Complete Randomized Design, which consists of two factors. Each treatment was repeated 4 times. The first factor is the thawing temperature with 3 levels of treatment those were 32°C, 37°C, and 40°C. The second factor is the thawing time with 3 treatment levels: 30 seconds, 60 seconds and 90 seconds. The variables were the motility percentage, viability, abnormality and membrane integrity. The results showed that thawing temperature had a significantly different effect (P<0.01) on the percentage of motility, viability, abnormality and membrane integrity. Thawing time had a significantly different effect (P<0.01) on the percentage of motility, abnormality and membrane integrity and gave affects significant (P<0.05) in the percentage of viability. Meanwhile, the interaction between thawing temperature and time is insignificant (P>0.05). The best result shown after thawing is in treatment thawing temperature at 37°C and treatment thawing time at 30 seconds.

Different dietary fiber stimulates eating behavior and rumination activity in Brahman crossbred calves

2024-02-08T01:56:08+00:00

Alteration in diet during a weaning period is often associated with changes in eating behaviour. This research evaluated the effect of providing different fibre sources on Brahman crossbred calves' eating behaviour and rumination activity. Ten Brahman crossbred calves aged eight weeks were randomly distributed into two dietary fibre treatments: COP = concentrate 40% + Pennisetum purpureum cv. Taiwan 60%; COM = concentrate 40% + Pennisetum purpureum cv. Taiwan 30% + Gliricidia sepium 30%). Feeding different dietary fibre changed the duration, percentage of eating time, and eating frequency ( P<0.05). Of the 9 hours of observation, 45,62% of the time was allocated for eating Pennisetum purpureum cv. Taiwan. Less time was spent eating a combination of dietary fibres (44, 31%). More frequent eating was observed in the COP group (20,88 times) than in the COM group (20,02 times). The treatments did not affect the drinking time (P>0.05). Providing a higher fibre diet in the COP group increased rumination frequency (P<0.05). However, it did not affect the duration and percentage of time of rumination during diurnal observation (P>0.05). In conclusion, feeding Pennisetum purpureum cv Taiwan as a dietary fibre during the weaning transition improves calves' eating behaviour and rumination activity.

Economic Impact of Foot and Mouth Disease (FMD) on Beef Cattle Fattening Businesses in Rembang Regency, Central Java

2024-03-30T23:09:58+00:00

This research aims to analyze the economic impact of FMD on beef cattle fattening businesses in Rembang Regency. The research was conducted in Rembang Regency on a beef cattle fattening business with 115 respondents. Of these 115 respondents, 46 groups of farmers whose livestock were not affected by FMD and 69 groups whose livestock were affected by FMD. Based on the R/C ratio value for both the group not affected by FMD and the group affected by FMD, the R/C value is < 1; it is considered that fattening cattle during an FMD outbreak is not profitable. The research results showed that the average income difference before FMD (2021) and during the FMD outbreak (2022) in the group of cattle not affected by FMD was IDR. - 6,659,570.68, while in the group of cattle affected by FMD, the average income difference was Rp. -7,900,693,088. Thus, the income difference between the group not affected by FMD and those affected by FMD decreased by -15.07%. This research concluded that the outbreak of FMD in Rembang Regency had a significant impact on the beef cattle fattening business; therefore, it is necessary to take preventive measures to prevent the occurrence of FMD in the following year by monitoring livestock movements, increasing immunity through FMD vaccination, increasing the number of Animal Health Centre as the spearhead of animal health in the field, and cross-sectoral coordination and collaboration (One Health) to eradicate the FMD outbreaks.

The Relationship Between Chest Circumference (CC) and Body Length (BL) to Body Weight and Daily Gain of Crossbreed Dorper Sheep

2024-03-30T06:23:46+00:00

This research aimed to determine the relationship between chest circumference, body length, body weight and daily gain in Crossbreed Dorper sheep. The samples used were 15 male F1 Dorper sheep and 15 female F1 Dorper sheep, aged 3.5 – 4 months, with an average weight of 30.88 ±0.847kg. The survey study was conducted using a random sampling method. The variables measured were chest circumference, body length, weight, and daily gain. The results of the study show that: (1) the regression equation for chest circumference on body weight Y = 0.77+0.64 CC for Rams and Y = 2.35+0.57 CC for Ewes, (2) the regression equation for body length on body weight Y = -30.27+1.12 BL for rams and Y = -16.59+0.80 BL for ewes, (3) multiple regression equation of chest circumference and body length on body weight Y = 7, 94+ 0.75 CC - 0.21 BL for rams and Y = -4.47+0.45 CC+0.22 CC for ewes. The correlation coefficient (r) is close to +1.0, indicating that the relationship between the two variables is powerful and positive. It was concluded that the chest circumference and body length have a solid positive relationship with body weight. The body weight of Crossbreed Dorper sheep can be predicted accurately using chest circumference and body length. However, the daily gain of Crossbreed Dorper sheep cannot be estimated using chest circumference and body length because the coefficient of determination is low.

2024-03-27T06:16:49+00:00

A survey was conducted in Kota Kupang to analyze the added value and factors influencing the added value obtained by broiler breeders and traders in Kota Kupang. The sampling methods were used in three stages, namely: first, the market determination was used using the census method; second, sample traders used a non-proportional random method; and sample farmers used the method of snowball sampling. The sample in this study was 25 respondents from breeders and 25 from traders. Data collection was carried out through observation, interviews, and documentation. The data analysis methods used are value-added analysis and linear multiple regression analysis. The research results show that the added value obtained by broiler chicken breeders in Kota Kupang is IDR 1,518.00/kg live weight, and broiler chicken traders are IDR 18,053.00/kg live weight. The conversion factor for breeders is IDR 1,620, and for traders, IDR 5,333. The statistical difference test results show no significant difference between the added value obtained by breeders and traders of broiler chickens in Kota Kupang. Linear multiple analysis shows that at the farmer's acquisition level, the factors influencing added value are the number of broiler chickens and production costs. At the broiler chicken trader level, the selling price of broiler chickens, the number of broiler chickens and production costs have no significant effect on the added value obtained.
