Mastitis is one of the most important diseases affecting production and reproductive efficiency dairy cows. The objective this study was to estimate prevalence subclinical mastitis (SCMA) its effects on performance in postpartum In a cross-sectional survey, sample cows (n = 200) within their 10-40 days milk from smallholder farms 159) were selected tested for SCMA using California Test. They cl...

In fact, breeders may be concerned about different kinds of problems which include but are not limited to true infertility (their bitches produce no pups after mating...

The influences of age and lactational period on the distribution, number and structure of somatomammotrophs (SMTs) and the relationships to changes in somatotroph and lactotroph populations in ovine were studied using immunocytochemical procedures with light and electron microscopy as well as morphometric techniques. Adenohypophyseal glands of 15 individuals of the Segureña bread (female lambs ...

Large-scale artificial insemination services in Queensland date from 1955. In that year a bull-proving project was inaugurated for the purpose of locating dairy sires of outstanding genetic merit from Queensland studs. The project requires the artificial insemination of at least 1,000 cows each year in the Nambour region of south-east Queensland. In September, 1957, an artificial insemination c...

There is worldwide interest in buffalo as an animal for meeting the growing demands of meat, milk and work in the developing countries. One of the major constraints to full exploitation of the productive potential of buffalo has been its inherently low reproductive efficiency as reflected by late maturity, poor expression of oestrus, silent oestrus, irregular oestrous cyclicity, seasonality in ...

To investigate endocrine mechanisms associated with the occasional occurrence of fertile oestrus during lactation in the high prolific Chinese Meishan (MS) breed, the incidence of oestrus and changes in plasma luteinizing hormone (LH) levels before and after oestradiol benzoate (OB, 15 micrograms/kg body weight) administration on day 22 was compared in 4 MS and 6 Large White (LW) sows. All sows...

A series of experiments was conducted to investigate the effect of basal feed level and increased feed intake during oestrus on ovulation rate, early embryo survival, and residual pituitary LH potency in the pig. All the gilts used were fed 1\m=.\8kg food/day from puberty to second heat. Gilts whose food intake was reduced from 1\m=.\8kg to 1\m=.\4 kg/day following second heat had more atretic ...

The purpose of this study was to understand how clinical social workers think about and utilize two distinct worldviews: the psychiatric perspective of DSM diagnosis (Diagnostic and Statistical Manual of Mental Disorders) and the contextual person-in environment perspective. The former is a requirement for service and reimbursement in nearly every clinical setting, while the latter has always b...
