“…After 2 months of supplementation, BCS increased significantly, reaching approximately the standard range (between 3 and 3.5) recommended by Maurya et al . [ 36 ] for breeding rams to exhibit better reproductive efficiency.…”

Effect of increasing levels of wasted date palm in concentrate diet on reproductive performance of Ouled Djellal breeding rams during flushing period

et al. 2018

Aim:The aim of the study was to assess the effect of two levels of wasted date (WD) by replacing commercial concentrate on the reproductive performance of Ouled Djellal (OD) rams.Materials and Methods:Eighteen mature (2-year-old) OD rams were equally allocated to three groups and fed during 11 weeks with one of three different experimental diets, that contained 0% (0 WD), 50% (50 WD), or 75% (75 WD) of WDs in concentrate diet. Live body weight (LBW), body condition scoring (BCS), scrotal circumference (SC), testicular weight (TW), sperm production and quality, plasma testosterone concentration (T), and sexual behavior (reaction time and number of mounts with ejaculation) were regularly recorded from every ram.Results:LBW, SC, and TW changed significantly among diet groups and during the experimental period (p<0.001), the highest averages were recorded in (0 WD) group. LBW, BCS, SC, TW, semen volume, and percentage of the positive hypo-osmotic swelling test were (p<0.001) positively influenced by flushing period. Nevertheless, sperm concentration showed a significant (p<0.001) decrease at day 30, followed by a return to the initial values afterward. There were no differences (p>0.05) between diet groups for plasma testosterone concentration and semen attributes, except that (50 WD) group expressed the lowest overall value of semen concentration. Furthermore, neither time nor diet affected (p>0.05) sperm motility and reproductive behavior parameters.Conclusions:It is possible to introduce WD as unconventional local feeding resources in flushing diet of breeding rams without disturbing their reproductive performance.

“…This study aimed to measure the effect of BCS over estral and ovarian activity of ewe after lambing. Is known that several factors influence the return to postpartum ovarian cyclicity in ewes, playing the nutrition an important role in follicular development, through a variety of endocrine, neural, and metabolic mechanisms and consequently influences the period from lambing until the first estrus and ovulation (Ascari et al, 2013), being the live weight and BCS a way for determine the nutritional status of sheep at different nutrition phases (Maurya et al, 2017).…”

The aim of the study was to evaluate the effect of body condition score (BCS) at lambing over the resumption of ovarian and estrous postpartum activity in lactating Pelibuey ewes. Twenty ewes were assigned to two groups, according to the BCS at lambing: Low BCS (LBC, n = 10) and High BCS (HBC, n = 10). Ovarian and estrous activities were daily monitored from day 3 postpartum until the first estrous or 90 days postpartum. Continuous variables were analyzed using Student´s t test and binary responses with the exact Fisher test. No significant effect of BCS at lambing on ewes in estrous, lambing to first estrous interval, estrous length, and estrous cycle length, preovulatory follicles at estrous, the maximum follicular diameter at estrous day or ovulation rate was observed. However, the lambing to first preovulatory follicle interval was shorter in the HBC group (HBC = 6.2 ± 2.6 vs LBC = 10.8 ± 4.5 d; P < 0.05). The lambing to first corpus luteum intervals were similar between groups, but without estrous expression. The function of the first corpus luteum postpartum was similar in both groups. BCS at lambing did not affect the resumption of ovarian and estrous activity postpartum in lactating Pelibuey ewes.

“…Although we were not able to quantify plasma testosterone, the previous study helps to explain a possible scenario indicated by the HSR rams in our study. Testosterone concentration is an excellent indicator of seminal production and quality, while spermatogenic activity is directly influenced by the level of testosterone released by the Leydig cells, the testicular endocrine component, modulating in turn the function of Sertoli cells, the gametogenic component of the testes [ 26 ].…”

Dorper rams (n = 24) were evaluated during the sexual resting season to determine their social rank (SR), either high (HSR) or low (LSR), under intensive management conditions in northern Mexico (25° N). Aggressive behaviors were quantified during male-to-male interactions, and appetitive and consummatory sexual behaviors during male-to-female interactions. Morphometric, live weight (LW), and body condition score (BCS) were recorded. During the early reproductive season, male-to-female behaviors were newly itemized simultaneously by seminal quality and quantity sampling. Finally, the dependent variables of the hemogram components were also quantified. Neither LW (61.25 ± 2.4 kg) nor morphometric variables differed between SR groups. However, BCS (2.25 vs. 2.66 u), sexual behaviors (i.e., approaches: 59.6 vs. 21.73 n, mating with ejaculation: 77.7 vs. 42.86 %, latency to ejaculation: 16.6 vs. 143.07 s), ejaculate volume (0.57 vs. 0.23 mL), and hemogram components favored the HSR rams (p < 0.05). Moreover, in their first male-to-female interaction, >50% of the LSR rams failed to display any sexual activity. HSR rams displayed a greater number of threatening behaviors, managing to displace LSR rams when exposed to estrus ewes during the male sexual resting season; more sexual behaviors; and an increased seminal volume in a non-live weight-dependent fashion.
