In order to optimise reproductive performance and thus production, it is now impossible to control the reproduction of dairy cows without the use of hormones. Due to the characteristics of dairy cows, the use of hormones not only reduces the need for visual heat detection and thus the number of undetected cows in heat, but also prevents certain problems associated with intensive production and its negative effects on reproduction.

Invitro Fertilization technology increases the genetic gain by reducing the generation interval. It helps to utilize a female cattle genetic potential fully and produce greater number of embryos in short duration with utilization of less semen. In

Abstract:

The world has advanced more than two centuries in the last 20 years in every aspect of existence. Every day, new inventions are made that improve our quality of life and make our lives easier. One aspect of contemporary innovation is the idea of the smart city. Many businesses and governments are embracing the idea of the "smart city" to improve quality of life for citizens while cutting costs. This model is made up of a variety of different technologies. Internet of Things, cloud and fog computing, UAV, and other technologies are among them. On the other hand, in order to achieve these import

Abstract:

Progesterone and progestagens are widely used to synchronise oestrus in sheep, however 15 to 30 % of ewes fail to maintain a pregnancy following the first service after oestrous synchronisation and the reason(s) for this failure rate is unclear. In commercial flocks, the progestagen treatment commences at a random stage of the oestrous cycle and in some ewes luteolysis may occur soon after treatment commences, leaving the ewe solely dependent on the exogenous source of progestagen which promotes the development of persistent follicles (Flynn et al., 2000). These persistent follicles may be up

AbstractIntroductionThe aim of the study was to determine the effect of the vitamins, omega-3 polyunsaturated fatty acid and minerals in the supplement Toryum administered before and during oestrus synchronisation on some fertility parameters of ewes during the non-breeding season.Material and MethodsThe experimental animals were clinically healthy Pirlak ewes, 55–75 days postpartum, aged 2–4 years and weighing 40–50 kg. A sponge was inserted into the vagina for 10 d (G1, n = 30; G2, n = 30) or 14 d (G3, n = 30; G4, n = 30) for oestrus synchronisation, and on the day of removal, 400 IU equine

Abstract:

The objective of this study was to determine the effect on pregnancy outcome of either inseminating heifers twice (at 48 and 72 hours after withdrawal of a controlled internal drug release insert (CIDR) containing progesterone) or once (56 hours after CIDR withdrawal) following a seven-day CIDR synchronisation protocol. Dairy heifers (n=267) from five farms, with an age range of 388–736 days, were randomly assigned to one of two treatment groups (group A heifers were inseminated twice; group B heifers were inseminated once). Both groups received a CIDR on day (D) 0 and an intramuscular injecti

Abstract:

This review aims to provide an insight into the application and efficiency of CIDR-based protocols for ES in goats raised under tropical and subtropical environments. In temperate regions, short-term CIDR treatments are replacing long-term treatments and sponges used in earlier decades. In addition, the use of co-treatments for the induction of ovulation is gradually changing from hormonal to non-hormonal methods, given the drive towards clean, green, and ethical techniques for reproductive management. Whereas the subtropical region registers ongoing research in the development of new ES proto

Abstract. This study compared the effects of natural mating and artificial insemination using frozen buck semen on reproductive performance in Alpine goats. Sixty reproductive Alpine goats were grouped according to natural mating (n=30) and artificial insemination (n=30) breeding methods. Oestrus was synchronised in experimental goats using a vaginal sponge impregnated with 20 mg of progestogen FGA (fluorogestone acetate) for 11 days. At the time of sponge insertion, 150 µg of prostaglandin F2α (PGF2α) analogue was injected intramuscularly. Forty-eight hours prior to vaginal sponge withdrawal,

Abstract:

The objectives of this study were to evaluate the effects of (1) double doses of PGF2α administration or (2) an exogenous progesterone (CIDR) applied concurrently with, or (3) the day after, first GnRH of Ovsynch (GnRH-1), on synchronisation and fertility during the Ovsynch protocol. All cows (n = 378) received the Ovsynch protocol (GnRH-7d-PGF2α-56h-GnRH-18h-TAI). The ‘OVS’ group (n = 105) received only the Ovsynch protocol. The ‘OVS-PGF’ group (n = 118, GnRH-7d-PGF2α-12h-PGF2α-44h-GnRH-18h-TAI) received an extra dose of PGF2α 12 h later on Day 7. The ‘OVS-7CIDR’ group (n = 78, GnRH+CIDR-7d-P

Résumé Dans cet article, nous analysons des interactions langagières, centrées sur le repérage et le traitement des erreurs, lors des leçons mathématiques en classes d’adaptation scolaire avec des élèves de 6 à 10 ans présentant des difficultés d’apprentissage et des troubles du langage. Les échanges langagiers entre l’enseignante et les élèves sont traités par une analyse de protocoles en tant qu’interactions de connaissances. Nous spécifions différentes fonctions didactiques attribuées par l’enseignante au traitement public des erreurs dans le cadre d’une interaction serrée avec l’élève qui
