“…In fact, it was clear that the calculated feed conversion ratios for all groups were exhibited comparable figures. These findings came in consistent with previous reports on rabbits (Beynen, 1988;Ayyat, 1991;Fernandez and Fraga, 1992), chickens (Scaife et al, 1994), cows (Palmquist and Jenkins, 1980;Whitney et al, 2000), fishes (Sener and Yildiz, 2003), and humans (James, 1988), but contradict other reports on chickens (Attia et al, 1994;Soliman et al, 1999;Vieira et al, 2006). It is possible that the disparity between these studies may be attributed to the depressed DM digestibility, insufficiency of metabolizable protein, and low plasma insulin-like growth factor-1 level, as well as to the variation of the dietary vegetable oils, their quality, and the inclusion process or rate.…”

“…One of the substantial advantages is that these vegetable oils are considered a rich source of essentially polyunsaturated fatty acids (PUFA; Baldini et al, 2000;Calvani and Benatti, 2003). In fact, supplying refined vegetable oils to mammalian and birds rations has been observed to have positive effects on growth rate, carcass traits and meat composition (Santoma et al, 1987;Beynen, 1988;Ayyat, 1991;Keteslegers et al, 1995;Soliman et al, 1999;Whitney et al, 2000;Vieira et al, 2006). However, it is not clear what are the subsequent effects of supplementing such oils on the reproductive performance (i.e.…”

Exploring new feeding strategies are a necessary aspect for improving the reproductive performance in rabbits. Twenty healthy rabbit bucks with a mean live body weight of 1.01 kg (SD = 0.12) and age of 6 months old were used for a period of 17 weeks to examine the influence of feeding soybean and sunflower oils on their reproductive performance. Rabbits were randomly assigned into 4 groups (5 bucks/group), where bucks in the 1st group, served as a control, were fed for 14 weeks on a standard ration without any oil supplementation, while bucks in the 2nd, 3rd, and 4th groups received -on the basis of the inclusion rate-a ration supplemented with 3% soybean oil, 3% sunflower oil, and 1.5% soybean oil plus 1.5% sunflower oil, respectively. Climatic, bio-physiological, blood and seminal measurements were all been determined. The obtained results suggested that offering rations supplemented with soybean and/or sunflower oils at the level of 3% of DM to rabbit bucks had no impacts on their health status, based on the findings that feed conversion ratio, blood hematology as well as liver and kidney functions were all not altered; thereby, indicating that the refined vegetable oils can be safely supplemented into rabbits rations. Most importantly, the collected evidences proposed that supplementing vegetable oil-enriched rations to rabbit bucks during their adulthood may demonstrate subsequent positive influences on their reproductive characteristics as early as the 3rd/4th week after feeding on such oils. This was generally manifested by the higher (P < 0.05) sperm concentration, total sperm output, percentage of motile sperms, as well as the lower (P < 0.05) percentages of dead and altered acrosomal sperms that observed in bucks compared to their control twins. Based on the obtained results herein, feeding rations supplemented with soybean and/or sunflower oils at the level of 3% of DM to rabbit bucks during their adulthood would produced an acceptable semen quality compared to the control bucks. Research dealing with such aspect may improve our understanding of the nutritional requirements and production of rabbits. However, further researches are definitely imperative because of the number of bucks per group was considerably low in the current experiment.

“…As the dietary potassium and chloride contents decreased from diet 1 to diet 4, a reduced water consumption and higher excreta DM contents were expected (Borges et al., ; Vieira et al., ), with resulting beneficial effects for the foot pad health of the animals. Although a high DM content of the litter is supposed to prevent foot pad dermatitis in broilers (Abd El‐Wahab et al., ; De Jong et al., ), in this study, groups with higher DM contents of excreta and litter were associated with high (= unfavourable) foot pad scores.…”

Summary Foot pad dermatitis (FPD) is of great concern in poultry industry, and dietary strategies are needed to improve foot pad health because of animal welfare and economic reasons. As the main factor for the development of FPD is the DM content of litter (consisting mainly of excreta; Kamphues et al., 2011), there are different dietary approaches to influence this disease pattern. In two consecutive trials, a total of 200 broilers were kept from day 7 until the 35th day of life. They were divided into four groups at each trial and fed with one of four experimental diets, based on wheat and corn mainly, but differing in the protein source: Group 1 was fed a diet with soya bean meal (SBM) as the main protein source, whereas Group 2, Group 3 and Group 4 were assigned to diets with 4, 8 and 12% of a protein‐rich (66.7% CP in DM) by‐product of swine slaughtering [Swine Protein Meal (SPM); in exchange for SBM]. The inclusion of 12% SPM resulted in a decreased dietary potassium content of about 3 g/kg diet (Group 1 vs. 4). Increasing dietary levels of the by‐product (8 and 12%) led to lowered feed intake (Group 1 vs. 4: ~10%) and weight gain (Group 1 vs. Group 4: ~8.5%). Although highest DM contents of excreta and litter were determined in Group 4, foot pad health was not influenced positively as hypothesized. Remarkable was the observed ‘stickiness’ of excreta when the by‐product was included in the diet at increasing levels, presumably due to the high proportion of bones in the by‐product. In conclusion, substituting SBM by 4% of the by‐product of swine slaughtering in broiler diets did not impair performance parameters, but led to the most favourable foot pad scores in this study.

“…Similarly, for the studies concentrated on broilers, soapstock supplemented diet does not effect live & carcass weight, feed consumption and feed conversation ratio (Bilal et al 1999(Bilal et al , 2001Vieira et al 2002;Baião and Lara 2005;Vieira et al 2006a). In addition, soapstock supplementation of 6% (Vieira et al 2006b) and 8% (Machado et al 2003) level doesn't have negative impact on broilers. On the other hand, according to Balevi et al (2001), amount of feed consumption and increase in live weight values showed differences and feed consumption was observed the maximum for the group having acidulated soapstock oil and increase in live weight was found to be maximum for the group having crude oil.…”

This research has been performed to determine the effects of hazelnut crude oil, sunflower crude oil and its refinery by-products over the laying hens performance and the fatty acid composition of the egg's yolk. Four hundreds 36-week-old Nick Brown layer hens were allocated into five groups. Treatment groups were supplemented with 1.5% of sunflower crude oil, hazelnut crude oil, acidulated sunflower soapstock, acidulated hazelnut soapstock and acidulated hazelnut crude oil. The daily feed consumption for groups that were fed with crude oils were numerically improved as compared for those nourished with acidulated soapstocks. Although the percentages of cracked and broken eggs in acidulated hazelnut soapstock group was significantly higher than the other groups, daily feed consumption and egg production values were not different. The usage of acidulated hazelnut soapstock reduced the percentage of intact egg ratio. Egg's specific gravity and yolk color index were the highest level throughout the experiment from start to end in hazelnut crude oil group (p < 0.05). In group that was nourished by hazelnut oil, Omega 3/Omega-6 fatty acid ratios in egg yolk were higher than the groups that were fed with sunflower oil. The oleic acid content of the egg yolk was increased in the groups which were supplemented with hazelnut crude oil and acidulated hazelnut crude oil. Consequently, hazelnut crude oil and acidulated hazelnut crude oil improved the egg shell quality, yolk color index and yolk oleic acid value which would increase egg's shelf life. On the other hand acidulated hazelnut soapstock supplementation adversely affects the quality of egg shell.
