Abstract

Water balance of 5 does of Kacang goat of Jeneponto was studied under the condition of sunlight exposure and water restriction. The study was conducted in dry season with 4 consecutive treatments of 10 d with 4-5 d of adjustment period between two consecutive treatments: (1) indoor and unrestricted water; (2) indoor and restricted water; (3) 10 h outdoor–and unrestricted water; (4) 10 h outdoor – restricted water. The maximum air temperature of outdoor was 39.3OC, and it was 30OC in the indoor environment. In all treatments, the animals were placed in the individual crates. The plasma volume of the goats was higher under sunlight exposure, but it decreased by water restriction, while hematocrite value indicated a reverse responses. Sunlight exposure did not significantly decrease the intake and digestion of organic matter, but water restriction affected significantly and this effect was higher under sunlight exposre. The proportions of water loss through every avenue were maintained relatively constant either under water restriction or sunlight exposure in which the respration rate increased significantly. The findings suggest that sunlight exposure with unrestricted water resulted in a positive water balance without a significant change in organic matter intake and utilization. Water restriction resulted in a negative water balance, reducing organic matter intake and utilization. As the adaptive mechanisms, the goat appeared to be able to withstand in the harsh environment of Jeneponto by expanding plasma volume, increasing body temperature and respiration rate.

Abstract

A morphometric study on ruminant kidney was conducted to elucidate the structural feature of the buffalo, cattle and goat kidneys which attributable with the urinary concentrating capacity. All kidney samples were collected from animals (3-5 years old) slaugthered in Tamangapa Slaugther House, Makassar. The external dimensions of the kidney were measured, including weight, thick, length and wide; the volume were measured according to the Archimedes principle, then used to determine specific density (ds.).  The internal dimensions measured were the cortex and medulla thicknesses, which then used to determine some indices : Percentage of Medullary Thickness, Relative Medullary Thickness and Medullary-Cortex ratio.  Data were analysed using the procedure of variance analysis based on factorial design of 3 (species) x 2 (sex) x 2 (location) with 5 replications of animal, then significant differences among mean values were determined by the procedures of Duncan Multiple Range Test. The results indicated that the ds and all internal indices were not significantly different between male and female or between left and right kidneys within the same species, while these parameters were significantly different in different species, and the mean value difference were consistent that goats > cattle > buffalo. Accordingly, it can be concluded that the goats with that kidney structural feature have higher concentrating capacity to produce a lower volume with higher osmolality of urine compared to that of cattle and buffalo. Therefore, as an implication is for the small herder, that understanding these characteristics (particularly relating with water availability) may be useful to boost the incomes and to improve the rural farmer livelihood in this region where these three species of ruminants are mostly managed.

Abstract

The study was aimed at scoring the body condition of Bali cows and its effect on thereproductive status. It was conducted in 14 smallholder farms in Bantaeng, South Sulawesi Province,Indonesia. A total of 64 Bali cows were involved in the study. All cows were subjected to bodycondition scoring (BCS; scale 1 - 9) and then clinically examined for reproductive status. The resultsof this study showed that most of cows had lower BCS (68%) and only 32% had BCS 5 or greater. Aproportion of cows with parities 1 and 2 were 61%, higher than parities 3 and 4; 28% and parity 5 orgreater; 25%. This study also noted that proportions of cows pregnant, cyclic and anestrous were25%, 9%, and 66%, respectively. Interval from calving (mean ± SD) to conception of these Bali cowswas relatively longer 191.3 ± 115.7 days and it expected calving interval of the cows approximately476 days. In conclusion, the Bali cows exhibited lower reproductive performance and lower BCS was the contributory factor.    Key Words: Bali Cows, BCS, Reproductive Status, Reproductive Performance

Abstract

Availability of meat and egg among rural communities comes from native chickens. However, the productivity of native chickens is still relatively low. The aim of this research was to determine the effect of in ovo feed of glutamine on hatchability and hatching weight of native chicken egg. As many 300 fertile eggs used, which were injected with glutamine at day 7 of incubation period. The research was arranged as a Completely Randomized Design (CRD) of 5 treatments, 3 replications. As for the treatments consisted of P0 (negative control); P1 (injected 0,5 ml 0,9% NaCl); P2 (injected 0,5 ml 0,5% glutamine in 0,9% NaCl); P3 (injected 0,5 ml 1,0% glutamine in 0,9% NaCl); P4 (injected 0,5 ml 1,5% glutamine in 0,9% NaCl). The results indicated that hatchability of the eggs fed in ovo by 0,9% NaCl (P1) and 0,5% glutamine (P2) were higher compared to the control and the other treatments. Thus, in ovo feed of glutamine on the 7thday of incubation resulted in higher hatchability with the injection of NaCl without glutamine and the hatching weight tended to bee higher at the level of 1,5%.

Abstract

Abstract. The aim of this study was to know the role of gender on biosecurity practices in beef cattle farms in Bone Regency, South Sulawesi. Total sample was 51 beef cattle farmers which was chosen through purposive sampling. Data were collected through observation and depth interview by using questionnaire. There was 22 questions which were divided into 5 sub variables: participation, isolation, sanitation, traffic control and other activities. Guttman scale was used to know whether beef cattle farmers take a part on those activities or not. The score was 1 if they DO, and the score was 0 if they DO NOT DO. Data were calculated by using SPSS version 23.0 and were analyzed descriptively by using percentage table. The results showed that the highest percentage was sanitation (69.02%), and the lowest percentage of the role of gender on biosecurity practices in beef cattle farms was participation (13.07%) which consisted of training, seminar and looking for information. On average, the role of men were greater than the role of women on biosecurity practices in beef cattle farms in Bone Regency, South Sulawesi: 54.70% and 45.30% respectively.

Abstract

In order to raise super-native chickens without the usage of antibiotics, herbal plants with a phytobiotic function may be used as feed additions. This study aims to examine the effect of turmeric flour (Curcuma domestica) given through drinking water on leukocyte differentials, AI antibody titers, and ND antibody titers as indicators of immunity status in super-native chickens. Five treatments and four tests, each with five super native chicks, were used in the experiment, which was carried out utilizing an experimental methodology. The treatment (P) given included P0 as a negative control (drinking water without treatment), P1 as a positive control (drinking water + 0.1 g/L PromuneC®), P2 (drinking water + 1 g/L turmeric flour), P3 (drinking water + 3 g/L turmeric flour) and P4 (drinking water + 5 g/L turmeric flour). All the data gathered for this study were evaluated using Analysis of Variance, and Duncan's test using SPSS version 25 was required if there were any significant differences. The 56-day-old AI and ND antibody titer reached a protective level where the best dose for AI antibody titer increase was 5 g/L of drinking water with AI log2 9.5 of titer and the best dose for ND antibody titer increase was 3 g/L of drinking water with ND log2 7.5 of titer. According to statistical analysis, the addition of turmeric powder to drinking water had no discernible effects on the mean of lymphocytes, monocytes, or eosinophils but had a significant impact (P0.05) on the mean of basophils. The treatment also had a noticeable effect on AI antibody titers (P<0.05) but had no noticeable effect on ND antibody titers. In conclusion, giving turmeric powder (Curcuma domestica) in drinking water is useful as an immunomodulator by maintaining normal levels of differential leukocytes, and increasing protection against AI and ND super-native chicken so it can be used as a natural feed additive.

Abstract

Ketersediaan daging dan telur di kalangan masyarakat perdesaan bersumber dari ayam kampung. Namun, produktivitas ayam kampung masih tergolong rendah. Penelitian ini bertujuan untuk mengetahui korelasi penambahan asam amino glutamin secara in ovo pada periode inkubasi terhadap daya tetas dan berat tetas telur ayam kampung. Sebanyak 300 telur fertil yang digunakan, yang diinjeksi glutamin pada hari ke–7 periode inkubasi. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 5 perlakuan, 3 ulangan. Adapun perlakuan yang diberikan terdiri dari P0 (kontrol negatif); P1 (injeksi 0,5 ml 0,9% NaCl); P2 (injeksi 0,5 ml 0,5% glutamin dalam 0,9% NaCl); P3 (injeksi 0,5 ml 1,0% glutamin dalam 0,9% NaCl); P4 (injeksi 0,5 ml 1,5% glutamin dalam 0,9% NaCl). Hasil penelitian menunjukkan bahwa daya tetas telur yang diberi in ovo dengan 0,9% NaCl dan 0,5% glutamin lebih tinggi dibandingkan dengan kontrol dan perlakuan lain. Tidak ada pengaruh yang signifikan pada penambahan in ovo glutamin terhadap berat tetas dibandingkan dengan kontrol. Dengan demikian, penambahan asam amino glutamin secara in ovo pada hari ke–7 inkubasi menghasilkan daya tetas yang lebih tinggi pada penambahan NaCl tanpa glutamin dan berat tetas cenderung lebih tinggi pada level 1,5%.
