Abstract
A study was conducted on twenty graded jamunapari goat kids fed on four different groups. Group I was fed solely on roughage, i.e. sola (Aeschonomene indica Linn) grass hay and rice straw (70:30). Groups II, III and IV were fed on de-oiled rice bran (100 g/d), urea molasses mineral granules (50 g/d) and urea molasses mineral granules (50 g/d) plus fi sh meal (25 g/d). The experiment lasted for 105 days. The effect of supplementing urea molasses mineral granules and fi shmeal was studied on rumen parameters, viz. microbial protein, bacterial and
protozoal biomass and blood biochemical constituents, viz. BUN, plasma creatinine, glucose, total protein, Ca and P. Enzymatic activity for alkaline phosphatase, aspartate transaminase and alanine transaminase were also measured. The microbial protein synthesis was higher in group III (42.94 g/100 ml) and IV (57.04 g/100 ml) as compared to control (I) and II. There was a signifi cant improvement of bacterial biomass (0.057 g/100 ml) and (0.082 g/100 ml). Similarly, bacterial and protozoal populations also become affected due to supplementation of
fermentable-N and bypass protein, like fishmeal in the diet. The BUN was signifi cantly (P<0.05) higher in group III (28.88 mg/100 ml) and IV (30.35 mg/100 ml) compared to control (I) and group II. Similarly, the activity of alkaline phosphatase was found to be higher in group III (29.77KA units) and IV (44.26 KA units), reflecting the better growth of kids in these groups. Other enzymatic activities were found to be unaffected. Concentration of plasma calcium and inorganic phosphorus were significantly (P<0.05) increased in groups III (9.85 and 9.93 mg/ 100 ml) and IV (7.57 and 8.31 mg/100 ml) compared to other groups. It is inferred that supplementation of fermentable-N and fishmeal in a catalytic amount increases the activity of bacterial and protozoal populations, some blood components and enzymatic activity which could support the growth of kids.Istraživanje je provedeno na 20 jaradi jamunapari pasmine. Prema načinu hranidbe, jarad je razvrstana u 4 skupine. Prva skupina hranjena je isključivo voluminoznom krmom - sijenom Aeschonomene indica Linn i rižinom slamom (70:30). Obrok 2., 3. i 4. skupine sastojao se od odmašćenih rižinih posija (100 g/d), granulirane mineralne melase ureje (50 g/d) i granulirane mineralne melase ureje (50 g/d) s dodatkom ribljeg brašna (25 g/d). Pokus je trajao 105 dana. Utjecaj dodavanja granulirane mineralne melase ureje i ribljeg brašna istraživan je na pokazateljima buraga odnosno mikrobnih bjelančevina, bakterijske i protozoalne biomase i biokemijskih pokazatelja u krvi, tj. BUN, kreatinina plazme, glukoze, ukupnog proteina, kalcija i fosfora. Također je određivana i aktivnost enzima alkalne fosfataze, aspartat transaminaze i alanin transaminaze. Sinteza mikrobnih proteina bila je veća u skupinama 3 (42,94 g/100 ml) i 4 (57,04 g/100 ml) u usporedbi s kontrolnom skupinom i skupinom
2. Značajno je povećana i bakterijska biomasa (0,057 g/100 ml odnosno 0,082 g/100 ml). Slično, bakterijska i protozoalna populacija su bile pod utjecajem dodatka «bypass» bjelančevina koje u obroku potječu od ribljeg brašna. BUN je bio statistički značajno (P<0,05) veći u skupini 3 (28,88 mg/100 ml) i 4 (30,35 mg/100 ml), a u usporedbi s kontrolnom skupinom (1) i skupinom 2. Također, utvrđena je veća aktivnost alkalne fosfataze u skupini 3 (29,77 KA jedinica) i 4 (44,26 KA jedinica), što je imalo utjecaja na bolji rast jaradi u tim skupinama. Aktivnosti ostalih enzima nisu bile promijenjene. Koncentracije kalcija u plazmi i fosfora bile su statistički značajno (P<0,05) povećane u skupinama 3 (9,85 i 9,93 mg/100 ml) i 4 (7,57 i 8,31 mg/100 ml) u usporedbi s drugim skupinama. Za pretpostaviti je da dodavanje fermentirajućeg-N i ribljeg brašna, u količinama koje djeluju katalitički, povećava aktivnost bakterijske i protozoalne populacije, podiže razinu nekih pokazatelja u krvi i aktivnost enzima. Navedeno može poboljšati rast jaradi
