AbstractThe aim of this research is to understand the influence of concentrate feed and mineral block formulation on the densitylevel and milk fat of dairy cattle. The research was conducted on eight cross breed friesian holstein cows with ± 450 kg body weight and aged 2-4 years with milk production 8-11 liter/head/day. The experimental design of this study was complete randomized design with two treatments and each treatment was repeated four times. P0 (grass, tofu waste) and P1 (grass, tofu waste, concentrate feed, mineral block). The data was analyzed using t test (independent sample t test ). The software that was used to analyzed the data is Statistical Program for Social Science (SPSS) version 20  for Windows. The results showed that concentrate feed and mineral block did not significantly affect the density of milk and milk fat (p > 0.05). The mean density of milk in the P0 was 1.0255 and P1 was 1.0253. Mean while the average milk fat in the P0 was 3.27% and in P1 was 3.45%. Keywords : concentrate, mineral block, density, fat, dairy cow

This study aims to determine the effect of fermented sago pulp in rations on performance (weight gain, feed consumption, feed conversion) and local sheep's income over feed cost (IOFC). This research was carried out in the community farms of Karang Rejo Village, Stabat District, Langkat Regency. This research started from March to June 2017. The design used was complete randomized design (RAL), with 4 treatment of 5 replications. Each replication consisted of 1 local sheep with an initial weight of 11.05 ± 0.56 kg. The treatment consisted of P1 (50% sago pulp without fermentation + forage), P2 (60% of sago pitch without fermentation + forage), P3 (50% fermented sago pulp + forage), and P4 (60% fermented sago pulp +). The observed variables were performance (body weight gain, feed consumption, feed conversion) and income over feed cost (IOFC). The results showed that the treatment of fermented sago pulp gave a very real effect (P <0.01) on daily weight gain. The mean of P1 = 33,05 g, P2 = 39,95 g, P3 = 46,57 g, P4 = 54,38g. The consumption of fermented sago pulp treatment has a real effect (P <0,01). With average P1 = 486,38 g, P2 = 548,68 g, P3 = 604,69 g, P4 = 671,11 gr. Against the conversion of fermented sago pulp fermentation treatment gave a real effect (P <0.05). With average P1 = 14.78, P2 = 13.90, P3 = 12.99, P4 = 12,49. IOFC the highest local sheep is Rp. 121.568 on treatment of P4 and IOFC lowest at treatment P1 equal to Rp.73.315. The conclusion of the research shows that the utilization of fermented sago pulp can increase body weight gain, feed consumption, local sheep feed conversion. P4 treatment economically has a better economic level than P1,P2 and P3.

First Case

A 2.5-years-old, Holstein lactating dairy cow was presented to the Veterinary Health Center with severe conjunctivitis and exuberant granulation tissue formation of the left eye. Upon close examination of the eye, a 2-cm long slender-shaped nematode was found in the conjunctival sac. The nematode was examined by a veterinary parasitologist and determined to be Thelazia species. The exuberant granulation tissue was surgically removed and a total of 0.5 mL of 1% levamisole was injected subconjunctivally. Levamesole was also injected subcutaneously at a dose of 10 mg/kg of body weight and repeated after 15 days. The cow made a complete recovery within 25 days following treatment. This is the first case report of ocular thelaziasis in dairy cattle in Jordan.

Modern freestall barns for dairy cattle have been constructed with considerations for dairy cow cleanliness; partitions and other stall features such as neck rails are designed to reduce manure contamination of bedding and decrease farm labor. However, cows prefer to lie in more open spaces, including on bedded packs and pasture. We created an “alternative” housing area by modifying a traditional freestall pen and including flexible partitions to create larger lying areas. We assessed cattle lying behaviour, including lying postures, in this alternative pen (ALT) compared to an open pack (OP) and freestalls (FS) with different stocking densities. We also assessed levels of manure contamination across systems. Cleanliness was highest in FS, but ALT provided substantial improvement compared to OP. Cattle spent more time lying down in OP and ALT compared to FS. There were few differences in postures (such as lying with limbs outstretched) between OP and ALT, but cows in both of these systems more often lay in extended positions compared to when they were housed in FS. Housing in OP and ALT was associated with reduced perching for cows with high body weight; perching has been linked to an increased prevalence of both hoof lesions and lameness. Thus, alternative lying areas can offer a solution for producers seeking to provide cattle with the advantages of a more open lying area, while improving hygiene relative to an open pack.
