“…The rams fed 15 % CP had a higher sperm motility than those fed 10 % and 20 % (Table 4), supporting the report by Ososanya et al (2014), who reported that West African Dwarf goats fed 14 % CP had greater semen motility than those given 12 % CP. Kumar et al (2015) also reported that feed restriction reduced the total motile spermatozoa, and slow spermatozoa were significantly higher in the nutritionally stressed rams. Sperm motility was significantly lower with poor feeding.…”

The increasing demand of the feed market for protein has necessitated the need to look for and use other sources of this nutrient. Cottonseed cake and palm kernel cakes are used extensively for supplementing ruminant rations to increase their productivity. The efficiency of sperm production, libido and quality of spermatozoa tend to remain uniform throughout the reproductive life of an animal but may be significantly altered by nutrition. The aim of this study was to assess the effects of graded levels of protein on semen characteristics, and serum testosterone profile in Yankasa rams. Fifteen rams aged between 18–24 months and weighing 15–25 kg with good body condition scores (3.5) were used in this study. They were divided into three treatment groups (A, B and C) according to the dietary protein level. Group A (n = 5) received 10 %, group B (n = 5) received 15 % while group C (n = 5) received 20 % combined crude protein of cotton seed and palm kernel cakes, respectively. Semen samples were collected weekly using battery-controlled electro ejaculator. Serum samples were harvested using a Pasteur pipette into serum vials and stored at −20 °C for analysis. These samples were from a representative animal in each group for determination of testosterone profiles using ELISA technique at weeks 1, 6 and 12. Data collected were expressed as means and standard error of the mean (± SEM). Significance of differences between treatments means were estimated at P ≤ 0.05 with Tukey-Kramer multiple comparison test of repeated measures analysis of variance (ANOVA). From this study, it was concluded that rams fed concentrate of 15 % crude protein using cotton seed and palm kernel cakes combined had improved semen characteristics in terms of semen concentration, motility, live sperm cells and morphology, but the crude protein levels had no effects on testosterone concentrations.

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

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.

“…They also observed that the noticed improvement in milk yield of does fed SP ration was associated with increasing growth rate of dams and their kids (Vishnu & Sumathi, 2014, Akporhuarho, 2015Hafez et al, 2015). The beneficial effects of additive SP related to the highest protein (El-Sabagh, Abd Eldaim, Mahboub, & Abdel-Daim, 2014), vitamin as β-carotene (Meza-Herrera et al, 2014), minerals mixture (Ahmad Fazel et al, 2014) and energy (Kumar, De, Saxena, & Naqvi, 2015). Khalifa et al (2016) found that Zaraibi kids at birth in Spirulina group nanny goats showed significant (p <0.05) higher average body weight than kids patronage by the control group as a result of improvement in milk production (quality and quantity).…”

This experiment conducted using 20 Rahmani ewes at the last third of pregnancy in two equal groups. One group served as control, while the other group received Spirulina platensis (SP) at the rate of 0.5 gm 10 kg-1 live body weight. The objective was to find out the effect of adding Spirulina platensis algae to small ruminant rations on reproductive and productive traits and blood components of sheep. The experiments lasted for 120 days for both dams and their lambs after weaning. The findings proved that adding SP in ewes' diets had no effect on the average of live body weight change. Average milk yield was significantly (p <0.01) higher in the treatment group than the control. Lamb's birth weight and daily body gain of the treated group were significantly (p <0.01) higher than the control. Blood and serum picture profile of ewes were significantly higher when fed SP additive than the control. It could be concluded that the addition of SP to the ration of sheep positively preserved their health, productive and reproductive status as well as their lambs' growth rate. Also the additive improved the economic efficiency of treated animals by about 53.13%.
