In the present study, we investigated the relationship between the temperature-humidity index (THI) and the conception rate of lactating dairy cows in southwestern Japan, one of the hottest areas of the country. We also investigated the relationship between measurement of the vaginal temperature of lactating dairy cows as their core body temperature at one-hour intervals for 25 consecutive days...

However, reproduction in sheep is seasonal, many breeds of sheep are able to mate not only in autumn, but out-of-season as well. The main factor determining seasonality is the photoperiod, but other factors can influence reproductive pattern, such as genetics, management practices and social cues. The fertility of spring and early summer breeding is usually lower; this imposes the need for alte...

Synchronization of estrus and ovulation are of paramount importance in modern livestock improvement programs. These methods are critical for assisted reproduction technologies, including artificial insemination and embryo transfer, that can increase productivity. In the current study, subcutaneous implants containing norgestomet were placed for long (14 days), medium (9 days), and short (5 days...

Dairy buffalo is the major source of milk production kept under peri-urban, low input production system. There is no practice of feeding animals according to requirements; exposing them to nutritional deficiency with the onset of pregnancy. It leads to a decline in milk yield, which compels the farmers to keep the animals un-bred. The present work was conducted to document, the post-conception ...

objective: an increasing number of studies have reported on shifts in timing and length of the growing season, based on phonological, satellite and climatologically studies. changes in the timing and length of the growing season (gsl) may not only have far reaching consequences for plant and animal ecosystems, but persistent increases in gsl may lead to long-term increases in carbon storage and...

The objective of the study was to evaluate chemical composition, in vitro dry matter digestibility (IVDMD), and growth performance of weanling Boer-goats supplemented with cowpea seed hulls (CSH) and commercial concentrate / feed (CF) with natural pasture as basal diet. Weanling Boer-goats (n=36) were assigned to 3 treatments comprising of 4 animals each (2 bucklings and 2 females) replicated t...

Two experiments were performed to determine the effectiveness of different progestogens contained in intravaginal devices, different doses of eCG and subsequent hCG treatment on the reproductive performance of estrus-induced mature Lori ewes. In the first experiment, 88 ewes were allocated into two groups, and were treated with either fluorogestone acetate (FGA) sponges or Controlled Internal D...

the aim of this study was to analyze the effect of sex, season and year of birth on growth rate of biometric measurements and body weight gain of thoroughbred foals during first six months of life. 103 thoroughbred foals (53 colts and 50 fillies) from golejewko stud born between 2006 and 2008, were used in this study. thoroughbred foals born in winter months were characterized by significantly ...

Background Persons living with HIV often face discrimination in safe sex and reproductive choices, especially in lowresource settings. This study assessed fertility desires and intentions, risk perception and correlates of ever use of at least one safer conception method among HIV-infected women attending a tertiary health facility ...
