This study was carried out to evaluate the immune response in young Ile de France (IF) and Santa Ines (SI) sheep naturally infected by Oestrus ovis and gastrointestinal nematodes (GIN). Mast cells, eosinophils and globule leucocytes were enumerated in the upper respiratory tract (septum, middle meatus and ventral nasal conchae) and in the mucosa of abomasum and small intestine. Immunoglobulin G...

Breeding records of 57 Arabian and 66 Thoroughbred mares were analysed to assess their reproductive performance under the subtropical conditions of Pakistan. The Arabian mares showed significantly higher conception rates (p<0.05) in second mated oestrus and foal heat mated oestrus compared to Thoroughbred mares. However, conception rates for first lifetime mated oestrus were similar in both bre...

Numerous studies have shown that it is possible to manipulate follicular and luteal dynamics, thereby eliminating the need for oestrus detection in embryo transfer (ET) programmes. Fixed-time ET (FTET) protocols are based on the use of gonadotrophin-releasing hormone (GnRH) and prostaglandin (PG) F or progesterone/progestogen (P4)-releasing devices and oestradiol. The FTET protocols increases t...

This study aimed to determine the effects of different lengths progesterone and equine chorionic gonadotropin (eCG) treatment on reproductive performance during non-breeding season in ewes. Progesterone-impregnated sponges were inserted intravaginally for 7 d Group 1 (G1, n = 24), 9 2 (G2, 25), 11 3 (G3, 24). On day sponge removal, eCG (350 IU) was injected 24 h later ewes exposed rams. Pregnan...

A total of 48 repeat breeder cows were equally divided in to two treatment groups as NOR and NOR-PG and were treated with norgestomet ear implants on day 10 following natural oestrus and a control group. At the time of ear implant insertion, 2 ml of SMB injection was administered intramuscularly to all the cows. The implant was removed after 9 days. Cows in NOR-PG group were injected with 0.98 ...

The aim of the present study was to compare endometrial gene expression profiles in a group of beef heifers yielding viable or retarded embryos on Day 7 after oestrus as a means of potentially explaining differences in embryo survival rates. Heifers were classified as either: (1) viable, when the embryo collected on Day 7 after oestrus was at the correct developmental stage (i.e. morula/early b...

Sixteen local adult goats were submitted for 9 weeks to 2.09 (high group) and 0.54 (low group) x dietary maintenance respectively. During the experimental period, goats were weighed, oestrus was detected and plasma insulin, urea, non-esterified fatty acids and progesterone concentrations were assessed. At the end of the experiment, ovarian small follicles population was studied by histological ...

Total ovarian blood flow of cows (sum of flows through the ovarian artery and uterine branch of the ovarian artery), measured by electromagnetic flow probes, followed a consistent cyclic pattern, being highest from Day 10 of the oestrous cycle (oestrus = Day 0) until 4 days before the subsequent oestrus. During this period of high ovarian blood flow, blood of uterine origin flowed to the ovary ...

In this case, semen that handled by urethral catheterization was deposited into the deepest point of vagina an anesthetized queen. Intravaginal artificial insemination applied on 2nd day onset oestrus and only single performed. Insemination time determined behavioural cytological evaluations. Two healthy kittens were obtained 62 days after insemination. The case has important reports in terms b...

Fibroepithelial hyperplasia (FEH) of the mammary glands in cats (also known as fibroadenomatosis or feline mammary hyperplasia) was first described in 1973 (1). The syndrome involves the usually reversible, rapid, non-neoplastic enlargement of one or more mammary complexes (4) and is not uncommon in female cats. There is no milk production. Around 20% of all feline mammary masses are non-neopla...
