The distribution of sialic acid residues as well as other glycosidic sugars has been investigated in the horse oviductal isthmus during anoestrus, oestrus and pregnancy by means of lectin and pre-lectin methods. Ciliated cells and non-ciliated (secretory) cells exhibited different lectin binding profiles that were found to change during the investigated stages. Ciliated cells did not show any r...

The reproductive activity of 84 female Blanca Andaluza goats was monitored over 17 months to determine the role of body condition score (BCS) and body weight (BW) in its control. Following a 3×2 factorial experimental design, the animals were allocated to three groups: low BCS (≤2.50, n=24), medium BCS (BCS=2.75-3.00, n=31) and high BCS (≥3.25, n=29). The same animals, irrespective of the BCS g...

The problem of postpartum anoestrus is a real one because it results in prolongation of the time between calvings. The interval between the calving and resumption of cyclic ovarian activity depends on several factors, i.e., amount of feeding before and after parturition, level of milk yield, age of the animal, calving difficulty, presence of a bull in the herd, season and its photoperiodism and...

The present study was undertaken to determine the predisposition of one transitional disease on other in various dairy animals Punjab. For this purpose, a total 250 respondents were randomly selected and interviewed personally from parts Punjab through structured interview schedule. Among diseases farms, anoestrus found be high (59.00%) followed by mastitis (52.00%). Dystokia highly significant...

A total of 135 postpartum suckled zebu cows were assigned randomly at calving to two treatments: cows exposed to vasectomised bulls (Mature Bull Exposure, MBE) and cows not exposed to bulls (No Bull Exposure, NBE) for a period of 150 days postpartum. This study was conducted to determine the influence of bull biostimulation, season and parity on postpartum reproductive performance of Bos indicu...

Bilateral olfactory bulbectomy was carried out on 16 post-pubertal gilts during the winter and spring of 2 consecutive years. Eight bulbectomized gilts in Exp. 1 had 2-7 regular periods of oestrus before becoming anoestrous for greater than 100 days in the summer and autumn. During November, 3 of these gilts were placed with b boar and became oestrous within 9 days, were mated and established n...

The length of oestrous cycles in a group of mature albino mice has been measured by the technique of daily vaginal smears. A high proportion of mice had prolonged cycles. It was shown that mice housed singly may experience abnormal cycles, the number being least when a wire loop is used for taking the smears. Housing mice in groups of four brought about an immediate cessation of normal cycling ...

AIM Anoestrus is one of the most common functional disorders of the reproductive cycle in buffaloes. In spite of technical advancement, there is no single cure for the management of anoestrus. Therefore, the aim of this study was to find out the efficacy of gonadotropic releasing hormone (GnRH) and metabolic hormone for the management of true anoestrus in buffaloes. MATERIALS AND METHODS The ...

In the study, 1118 Polish Black and White cows from a dairy herd were examined during a three-year period. Three hundred and eighty-eight (34.7%) animals showed no visible oestrus signs until day 60 post-partum. In those cows clinical examinations were performed twice, with a 10 day interval, and blood samples for progesterone analysis were collected simultaneously. Progesterone was measured by...
