in may 2007, a suborder shoka deer calf about one month of age was found in a preserved area of arasbaran in the east azerbaijan province. from an ecological view point, the arasbaran area is uniquely labelled as a reserve biosphere. he calf had diarrhea that recovered after treatment. during rearing, the calf received pasteurized- homogenized milk from market as well as milk of a goat. after 3...

despite the availability of various alkaline phosphatase (alp) isoenzymes, the calf enzyme is being used in current enzyme assays as the detector enzyme. the glycosylation pattern of this enzyme makes it a suitable ligand for binding to wheat germ agglutinin lectin (wga). as a result of this property, the enzyme can not be used as a conjugate with this lectin, and the calf enzyme conjugates can...

OBJECTIVE To characterize lymphatic vessel morphology in lower extremity lymphedema using MR lymphography at 3T. STUDY DESIGN Forty females with lower extremity lymphedema secondary to gynecologic carcinoma treatment underwent MR lymphography (MRL) at 3T. Lymphatic vessel morphology in normal and affected limbs was compared. RESULTS The median diameter of the lymphatic vessels in swollen ca...

Spergualin (SG) and 15-deoxyspergualin (DSG) were more slowly incorporated into L5178Y cells than spermidine. SG and DSG inhibited carrier-mediated transport of [3H]spermidine competitively with inhibition constants of 0.67 mM and 0.45 mM, respectively. Addition of calf serum stimulated uptake of [3H]spermidine into the cells in a serum concentration-dependent manner. The effect was not observe...

We investigated nursing behavior on the Hawaiian breeding grounds for first year humpback whale (Megaptera novaeangliae) calves. We observed and video-documented underwater events with nursing behavior from five different whale groups. The observed nursing events include behaviors where a calf positions itself at a 30-45° angle to the midline of the mother's body, with its mouth touching her ma...

Human safety can be compromised by the response of beef cows to handling or when defending their calf. However, little is known about how precalving temperament, postcalving defensiveness, and maternal care are related. The impacts of cow temperament on calf neonatal vigor and ADG are also unknown. Data were collected on 2 farms (Farm 1, n = 143, 1 parity; Farm 2, n = 237, 2 parities). Temperam...

The tropics is not an ideal location for calf rearing as the high temperatures and humidities introduce many potential disease problems to milk fed calves. In addition, the type of dairy farming (generally poorly resourced small holder farming) and the general lack of awareness of the long term implications of poorly reared stock do not encourage farmers to pay close attention to their calf and...

Heritabilities of and genetic correlations between additive direct and maternal genetic effects for calf market weight, and additive direct genetic effects for carcass traits, were estimated for Japanese Black cattle by REML procedures under 2-trait animal models. Data were collected from calf and carcass markets in Hyogo and Tottori prefectures and analyzed separately by prefecture. Calf marke...

segment of the integrated management program in an efficient beef cow production system. The main objective should be to develop an adequate number of heifers to a point where they reach puberty and are cycling regularly at the start of the breeding season. In addition, they should have adequate pelvic area to deliver a reasonable size calf unassisted. Because of her increased nutritional needs...

BACKGROUND It has been reported that calf oocytes are less developmentally competent than oocytes obtained from adult cows. Bone morphogenetic protein 15 (BMP15) and growth and differentiation factor 9 (GDF9) play critical roles in folliculogenesis, follicular development and ovulation in mammalian ovaries. In the present study, we attempted to compare the expression patterns of BMP15 and GDF9 ...
