Influence of feed intake on blood chemistry parameters in Kacang goats was studied. Nine clinically healthy female adult goats were used in this study. Animals were kept in individual box for 8 weeks. During the first 4 weeks the animals were fed at the level of about 40% of the feed requirement for maintenance plus medium activity (the restricted feeding period) and during the 5 th -8 th week (the fullfeeding period) they were offered full feed intake for maintenance plus medium activity (dry matter intake at the level of 3% of body weight). Feed intake was measured daily and the body weight was measured weekly. Blood samples were collected at the end of the 4 th week and the 8 th week for blood chemistry analyses. Paired t-test was used to evaluate the effects of feed intake on blood chemistry parameters. Restricted feeding (0.320±0.065 kg dry matter/d) for 4 weeks in clinically healthy female adult Kacang goats resulted in a decrease of body weight gain as well as serum calcium and protein concentrations, but in an increase of serum creatinine and inorganic phosphate concentrations. No significant feed intake related changings of blood pH and base excess were observed. There were some indications that the animals might use their fat and protein as energy reserves during the restricted feeding. In conclusion, nutritional status has significant influence on some blood chemistry parameters in Indonesian Kacang goats. Serum calcium, inorganic phosphate, creatinine, and protein concentrations are nutritionally related blood metabolits which are useful for assessment of nutritional status in Kacang goats.

Influence of body condition score on the metabolic and reproductive status of adult female Kacang goats

“…However, in comparison with the blood glucose levels of female Kacang goats (non-pregnant and non-lactating which were given adequate feed) reported previously, i.e. 73.88 ± 13.56 mg/dL (Widiyono et al 2016), the Kacang goats' blood glucose levels in the recent study were relatively low and needed intervention to attain optimum levels for regulation of GnRH release and the reproductive cycle.…”

Undernutrition dan Anestrus Pada Kambing Bligon Betina Umur 2-3 Tahun: Sebuah Studi Kasus

“…Pembuatan preparat apus vagina, pengecatan Giemsa dan pemeriksaannya dilakukan dengan metoda yang dijelaskan oleh Kraft dan Duerr (1999) dan Ola et al (2006). Pertambahan bobot badan harian diperhitungkan berdasarkan selisih antara bobot badan pada akhir dan awal suatu periode pengamatan dibagi jumlah hari dalam periode pengamatan tersebut (Widiyono et al, 2016). Untuk mengetahui status organ reproduksi pada hari ke-3 setelah pemberian PGF2α yang kedua (akhir minggu ke-8) dilakukan pemeriksaan Ultrasonografi (USG) per rektal.…”

“…Hasil penelitian ini selaras dengan hasil penelitian pada kambing yang dilakukan beberpa peneliti terdahulu. Widiyono et al (2016) melaporkan bahwa pemberian pakan 40% dari kebutuhan hidup dengan aktivitas medium pada kambing Kacang betina dewasa selama 4 minggu mengakibatkan PBBH negativ dan penyusutan bobot badan. Lebih dari itu, dari penelitian tersebut ditemukan adanya indikasi kuat bahwa kambing Kacang menggunakan lemak dan protein tubuhnya untuk memenuhi kebutuhan selama masa kekurangan nutrisi.…”

“…Widiyono et al (2013) melaporkan pemberian pakan yang terbatas (80% dari kebutuhan maintenance) selama 4 minggu pada kambing Peranakan Ettawa mengakibatkan penurunan bobot badan yang signifikan, dari 39,50 kg menjadi 37,13 kg. Pemberian pakan pada level 40% dari kebutuhan maintenance (320 kg/hari) selama 4 minggu mengakibatkan penurunan bobot badan yang signifikan dengan PBBH negativ sebesar -80 g/hari (Widiyono et al, 2016). Demikian pula, Dashtizadeh et al (2008) menemukan hal serupa terjadi pada kambing Iran.…”

Posisi kandang kambing diantara bukit -bukit Kambing kacang juga merupakan kambing lokal yang mudah beradaptasi dengan potensi pakan lokal (Kustantinah et al, 2016), reproduksinya cukup bagus pada kondisi pakan yang kurang (Suwignyo et al, 2017;Widiyono et al, 2016;Sarmin et al, 2017) dan warga sudah terbiasa membudidayakan kambing kacang.…”
