چکیده
47 NC and AC1 treatments (P<0.05). N digestibility was higher in both PC and AC3 treatments compared with NC and AC1 treatments (P<0.05). The RBC count was increased in ALA treatment compared with NC treatments (P<0.05). Hemoglobin in AC2 treatment was higher than NC treatment (P<0.05). Lymphocyte, WBC, IgG and total iron binding capacity were not affected among all treatments (P<0.05). The reduction of total protein was higher in NC treatment than PC, ALA, COS and AC3 treatments (P<0.05). Iron concentration was higher in ALA and all of the AC treatments than NC treatment (P<0.05). In conclusion, supplementation of 3 ppm ALA or 5 ppm ALA with 0.5% COS may have benecial effects on weanling pig.

The “Male Effect” Onestrous Synchronization and Reproductive Characteristics of Female Markhoz Goat during the Breeding Season
One hundred female Markhoz goats (42±5 kg) were used to investigate the ‘male effect’ on estrous synchronization and reproductive characteristics of female goat during the breeding season. This was carried out in three separate experiments. In the first experiment, forty female goats were used in 4 groups with different distance from the male goats (i.e. source of pheromone secretion); A1 (1 me...
متن کاملEfficacy of CIDR, fluogestone acetate sponges and cloprostenol for estrous synchronization of Nadooshani goats during the breeding season
The objective of this study was to evaluate three methods of estrous synchronization, viz. controlled internal drug releasing device (CIDR), intravaginal sponges impregnated with fluogestone acetate (FGA), and cloprostenol (Estrumate; an analogue of prostaglandin F2α) in Nadooshani goats of Yazd province, Iran.The estrous synchronized does (n = 30 to 33 per treatment), after heat detection, wer...
متن کاملPhysiology and Endocrinology: Synchronization of Estrus in Cattle
McKenzie’s laboratory (U. MO; 1930s) described the estrous cycle of domestic animals. Brownell (Cornell; 1936) reported AI and bull bred pregnancy rates were similar. Between 1938 (first, EJ Perry, NJ) and 1940, 54 AI organizations in 21 states were formed. Ulberg, Christian and Casida (1951) controlled time of ovulation in cows with progesterone (P) injected daily. Trimberger and Hansel (1955)...
متن کاملEffects of estrogen and estrous cycle on glucocorticoid and catecholamine responses to stress in sheep.
There have been relatively few studies of the effects of estrogen on hormonal responses to stress. We therefore studied changes in ACTH, cortisol, norepinephrine (NE), and epinephrine (Epi) after stress induced by a barking dog (audiovisual stressor) and insulin-induced hypoglycemia (metabolic stressor) in ovariectomized sheep treated with estradiol or placebo and in intact sheep in the follicu...
متن کاملMale-induced estrus synchronization in the female Siberian hamster (Phodopus sungorus sungorus).
Olfactory cues play an integral role in the organization of events that mediate reproductive success. In a variety of species, priming pheromones, in particular, are important for ensuring reproductive fitness. To date, very little research has focused on how male-emitted priming pheromones, such as those that regulate the onset of puberty and estrus synchronization in females, affect the repro...
متن کاملEffects of diet and exposure to hindlimb suspension on estrous cycling in Sprague-Dawley rats.
Various factors can disrupt the female reproductive cycle resulting in subfertility. The primary objective of this study was to determine whether physiological changes associated with exposure to hypogravity disrupt reproductive cycles. The hindlimb suspension (HLS) model was used to simulate the major physiological effects of hypogravity in female Sprague-Dawley rats. Also, to determine whethe...
