JOURNAL FREE ACCESSUsing forty Japanese Shorthorn feeder cattle, reproduced in Iwate Prefecture in 1973, the effect of the rearing in mountainous region on the fattening efficiency of the cattle, was investigated in reference to their lipid metabolism. These cattle were divided into three groups according to the rearing and fattening areas, i.e. the cold plain rearing-cold plain fattening (SC), the cold mountain rearing-cold plain fattening (AC), and the cold mountain rearing-warm plain fattening (AW). On the mountain rearing cattle, the physiological conditions adapted to that environment were remained until the final stage of the fattening, independently to their fattening areas. In the AW group, especially, the serum concentrations of non-esterified fatty acid, triglyceride, and total cholesterol were higher than those of the other two groups. It was assumed that the fattening level of these individuals was better developed than the others. From these results, it is reasonable to presume that the feeder cattle reared at mountainous regions were compelled to complete their metabolic conditions in order to survive in the severe circumstances. These conditions remain more or less at the fattening stage, and promote the fattening efficiency, especially, these effect were remarkably accelerated by means of the transference of cattle from the mountain to the plain in warmer area.View full abstractDownload PDF (310K) -

JOURNAL FREE ACCESSMycological survey was carried out on total 131 samples including raw milk(41), feed (43), and cow's hair (47). All of the samples were collected in four seasons in Okayama. The isolated fungi were counted and identified. Fungal plate counts were 6.0×103/ml in raw milk, 1.3×103/g in feed, and 1.6×104/g in cow's hair. Numbers of the isolated fungal species per sample were 0-3 in raw milk, 1-9 in feed, and 1-10 in cow's hair. Genera frequently isolated in all of the samples were Aspergillus (57.3%), Penicillium (42.0%), Fusarium (26.7%), Mucor (26.0), Cadosporium (17.6%), Geotrichum (16.0%), Phoma(13.0%) and Alternaria (10.7%). Dominant groups of Aspergillus in frequencies were A. niger (18.3%), A. jiavus (17.6%), A.terreus (16.0%) and A.versicolor (11.5%). Dominant series of Penicillium were P. decumbens (16.0%) and P.restrictum (7.6%). However, the pattern of fungal contamination of raw milk differed from that of feed and cow's hair. The dominant genus in raw milk was Geotyichum. There is no appreciable seasonal vicissitude of the fungal distribution, although the fungal counts in spring were generally lower than those in other seasons.View full abstractDownload PDF (164K) -

JOURNAL FREE ACCESSHuman erythrocytes were tested with various proteolytic enzymes and examined on the characteristic of Q-antigen. The results obtained were as follows; the treatment with trypsin, papain and ficin induced the increased reactivity of Q-antigen and the determination of Q-blood groups was faciliated even by pig anti-Q hemoagglutining which haslow hemoagglutination titer. Besides, through the treatment of human erythrocytes with pronase or dispase, q red cells obtained Q like antigenecity. However, serological studies indicated that the Q-antigen is not related changes in Q like antigen induced by pronase and dispase treatment, and this reaction seems to be due to the heterogeneity of antibody activities of pig serum. The pig anti-Q hemoagglutinin is specifically inhibited n its agglutination reaction by oligosaccharrides that contain D-glucosamin, D-galactosamin and D-galactose.View full abstractDownload PDF (188K) -

JOURNAL FREE ACCESSNine lactating cows were used to compare the feeding value of three silages; early maturing corn (early yellow ripe stage), late maturing corn (early milk stage) and firstcutting timothy (early heading stage). A replicated 3×3 Latin-square design with 21-day periods and individual feeding was used. The cows were fed silage ad libitum, 1kg of concentrate per 5kg of actual milk and 2kg of hay per cow daily. The average intakes(kg)of silage (dry matter), actual milk and 4% fat-corrected milk, and the average percentages of milk fat, solids-not-fat and protein of the cows fed the three different rations were as follows: early maturing corn silage 13.7, 19.1, 18.3, 3.76, 8.77, and 3.42; late maturing corn silage silage 10.5, 16.6, 15.7, 3.65, 8.73, and 3.18; and timothy silage 12.9, 18.9, 17.8, 3.63, 8.68, and 3.21. Consumption of late maturing corn silage was significantly lower(P<.01)than other silages. The percentage of milk protein of early maturing corn silage was significantly (P<.05) higher than other silages.View full abstractDownload PDF (322K) -

JOURNAL FREE ACCESSThis paper is concerned with studies on the traits such as body size and coat color of Miyako horses as well as their history of improvement. Miyako horses were classified into four types: the native, the small, the middle and the large. The ages for these four types were over 25, over 20, 11-19 and 4-10 years old, respectively. 1) Each body section measured was significantly increased as improvement proceeded. Comparing the native type with the large type, the differences for females and males in withers hight, body length, chest girth, hip width and rump length were 25, 24; 19, 20; 26, 27; 11, 9 and 14, 8cm, respectively. 2) The native type with relatively higher body length, head length and chest girth, but lower rump length, comparing with withers hight was found to have been improved to the large type which was relatively high in rump length and thurl width. 3) The coat colors of the 497 Miyako horses were mainly chestnut (55%), bay (33%) and black (6%) with very few cases of roan, fallow and isabell. 4) Forty eight stallions have been introduced to Miyako island during the period from 1928 to 1975. Of these animals, four sires named Rakumu, Matsukaze, Hatsuteru and Sanho shipped from Miyasaki prefecture have made a great contribution to the improvement of Miyako native horses. 5) The coat colors of the 48 stallions introduced were chestnut, 23; bay, 21 and black, 4. Twenty four of them were from Miyazaki prefecture. Most of the 48 stallions were mainly Anglo-Arab or Anglo-Norman, which were not pure breeds, and a few Breton. 6) After World War II, 45 stallions were established in Miyako island and 28 of them were sons, grandsons or great-grandson of Rakumu.View full abstractDownload PDF (467K) -

JOURNAL FREE ACCESSLaying hens were fed the diets supplemented with 10% of fat or oil (tallow, lard, soybean oil or cocount oil) for a period of 50 days, and the changes of fatty acid compositions of yolk lipids and the fatty acid distribution in yolk triglyceride affected by dietary fat and oil were studied. The feeding of diet supplemented with tallow or lard resulted the increase in C18:1 acid, the decrease in C16:0 and C18:2 acids in total lipids of egg yolk and the decrease in C20:4 and C22:5 acids in phospholipid of eggs. The feeding of soybean oil resulted the decrease in C16:0 and C18:1 acids and considerable increase in C18:2 acid in egg yolk lipids, and in phospholipid fraction of eggs, C22:5 decreased and C18:0 decreased on soybean oil feeding. The feeding of coconut oil resulted the increase in C14:0 and C16:1 acid and the decrease in C18:1 and C18:2 acids in total and neutral lipids of egg yolks, and on the other side, resulted the increased in C18:1 acid and the decrease in C20:4 and C22:5 acids in phospholipid of eggs. The fatty acid distribution in triglyceride was determined with the aid of pancreatic lipase hydrolysis. Although the fatty acid distribution in triglyceride of tallow was remarkably different from that of lard, not so much difference was observed between the yolk lipid from hens fed tallow and from hens fed lard on the fatty acid distribution in their triglycerides. The yolk lipid from hens fed soybean oil was considerably different with that from hens fed coconut oil on the fatty acid compositions of triglycerides, but in any case, C16:0 and C18:0 acids were found to be preferentially esterified at the 1, 3-position in triglycerides and C18:2 acid predominantly linked at the 2-positions. The triglycerides in yolk lipids such as SUU and SUS tended to decrease and SSS, SSU and UUU increased on tallow feeding to hens. On lard feeding, SUS decreased and UUU increased in yolk lipids. The feeding of soybean oil resulted the considerable decrease in SUS and the increase in UUU in yolk lipids, and on the contrary, coconut oil feeding resulted the increase of SSS, SSU SUS and USU, and the decrease of SUU and UUU in yolk lipids. Concerning to the major component triglycerides in yolk lipids, PLP, PLO and OLO decreased and POO and OOO increased on tallow feeding to hens. On lard feeding, PLP and POPt decreased and OOO increased in egg lipids. The soybean oil feeding to hens resulted the decrease of POP, POSt POO and OOO in yolk lipids, and the distinct increase of PLP, POPt, StLO, PLL, OLO and OLL. On the other hand, coconut oil feeding resulted the decrease of PLP, POO, PLO, OOO and OLO, and the increase of MyOP and MyOO in yolk lipids. (Abbreviation used in this were as follow; S: saturated, U: unsaturated, P: palmitic, Pt: palmitoleic, St: stearic, O: oleic and L: linoleic acid).View full abstractDownload PDF (629K) -

JOURNAL FREE ACCESSThe precipitate prepared from the ovarian homogenate with saline of immature rats pretreated with gonadotropins possessed predominatly an alkaline protease activity which had an optimum pH at about 8.5. This alkaline protease required a high ionic strength (μ=1.0) to be solubilized, and the solubilized alkaline protease was strongly inhibited by the supernatant of the ovarian homogenate. For these reasons, centrifugation of the homogenate and 1.0M NaCl extraction of the precipitate resulted in about 17-fold purification of this protease with about 140% recovery of the initial activity in the original homogenate. The solubilized alkaline protease was strongly and considerably inhibited by Cu2+ or Zn2+, and by TPCK, EDTA, cysteine, SbI, 2-mercaptoethanol, or DFP, but was moderately activated by Ca2+. The solubilized alkaline protease was considerably stable at the temperature below 37C under the pH condition of 6-9, but unstable even at 4C under the pH condition of 3.View full abstractDownload PDF (332K) -
