“…Many studies in the literature reported the absence of diet effect on goat daily milk production similarl to the present results [38]. Indeed, many authors [22][23][24]39,40] already reported the absence of OC effect as block, silage, dried and partially stoned in the diet of cows, ewes, or dairy goats. The lack of CC effect on goat milk production is in agreement with observations of Ichimura et al [20] with 20%, and Atti et al [25] and Mahouachi et al [27] with ad libitum spineless varieties of cactus.…”

In the Mediterranean area, the olive cake (OC) and cactus cladodes (CC) are two alternative resources widely available that could be used for ruminants’ feeding. The objective of this study was to evaluate the effects of OC and/or CC diet incorporation on the production performance and quality of goat milk. Forty-four lactating goats were randomly allocated to four groups. The control one (Co) received a conventional feed. Test groups (TOC; TCC and TOC+CC) received 20% OC, 30% CC, or 15% OC and 20% CC, respectively, on concentrate dry matter basis. Over three months, milk production was evaluated, and samples were collected to analyze the milk quality. No significant differences were observed between control and test groups for daily milk production, yield, composition and acidity. In milk fat, OC incorporation increased C18:1n-9, mono-unsaturated (MUFA) and n-9 fatty acid (FA), and decreased 9t-C18:1 and poly-unsaturated FA (PUFA) (p < 0.05). Significantly highest contents of C15:0, C18:1n-9, and C21:0, and lowest levels of C4:0, 9t-C18:1, 6t-C18:2, C20:0, and PUFA were obtained with cactus cladodes administration (p < 0.05). The TOC + CC diet reduced C4:0, 9t-C18:1, 6t-C18:2, C22:6n-3, and PUFA proportions, and increased C18:1n-9, MUFA/PUFA, and thrombogenic indexes. The incorporation rates of OC and CC that could reach 20% and 30%, respectively, had no major negative effects on milk production performance, composition, and quality. Thus, they could be introduced in the diets of lactating goats.

“…Many studies have evaluated the effect of OC on cows and ewes. To our knowledge, there are few published studies on the effects of OC [22][23][24] and cactus cladodes (CC) in the lactating goat [25][26][27]. Furthermore, no studies have investigated the effect of the incorporation of OC and CC mixture in the goats' diet.…”

“…Similar to our results, Obeidat et al [8]; CARP), Obeidat et al [16] (BB), and Janicek et al [24] (DDGS) observed no effects on milk production and composition when AF were included in the diet. Recently, Keles et al [25] supplemented dairy Saanen goats with OC silage at 0, 100, and 200 g/kg of dietary DM and observed no effect on milk yield, CP, lactose, energy corrected milk (ECM), fat corrected milk (FCM), or feed efficiency, while fat content and fat production increased. Diets containing OC silage may have produced milk with a higher fat content due to its high level of fiber (NDF and ADF) and, subsequently, more volatile fatty acids were generated (mainly acetate; the major precursor for fatty acid synthesis).…”

Simple SummaryAlternative feeds have been used to feed animals for decades by replacing traditional feeds to increase the profit of raising livestock. In this study, alternative feeds (dried distillers grains with solubles, carob pods, olive cake, and bread by-product) were fed to Awassi ewes and ewe lambs at 0, 200, and 400 g/kg. Chemical composition was similar among diets. Feed intake, body weight change, and milk yield did not differ among diets. Cost of milk production decreased in alternative feeds containing diets, with no negative effect on health, welfare, and productivity.AbstractTwo experiments were done to assess the effects of alternative feeds (AF; dried distillers grains with solubles, carob pods, olive cake, and bread by-product) on lactating performance of ewes and digestibility and nitrogen (N) retention of lambs. Diets were: no AF (CON); 200 g/kg AF (AF200); and 400 g/kg AF (AF400). In Experiment 1, 27 Awassi ewes were randomly distributed into three groups, and each was fed one of the diets described before (9 ewes/diet). Evaluation of milk composition and yield was performed at the beginning of the experiment and on days 18, 36, and 54. In Experiment 2, 18 Awassi lambs were allocated to the same diets (6 ewe lambs/diet) during a 21-day trial (14 days housed individually in shaded pens and 7 days in metabolic cages). In Experiment 1, no differences in body weight (BW) of the ewes and their lambs were detected. With the exception of neutral detergent fiber intake, which was lower in the AF-containing diets compared with CON, dry matter, crude protein, and acid detergent fiber intake were not affected by dietary treatment. Milk yield and composition was comparable among diets, and the cost of milk production was lower in AF compared to CON diet. In Experiment 2, nutrient digestibility and N retention were not affected by the diet. Results showed the possibility of including different AF in ewe and lamb diets to mitigate production cost without negatively affecting intake, milk yield, and composition, digestibility, and animal welfare and health.

“…This could be due to a better utilization of the energetic quota by the lactating goats, which had the diet integrated with olive cake. Regarding milk fat yield, its value was significant higher with FWOC rationsR2 and R3than that of control one R1.Also, Keles et al (2017) mentioned that milk fat concentration increased markedly with increasing olive cake level from approximately 3.75-4.45%, presumably because of increasing dietary levels of ether extract.…”

his study aimed to evaluate the effects of diets composed of ecological food waste (mixture of food waste from hotels and olive cake(FWOC)) on lactating goats productivity compared with traditional diets. The effect of inclusion mixture of food waste and olive cake in diets of Zaraibi goats on nutrients digestibility, rumen function, milk yield, milk composition and some blood parameters were studied. A feeding trial was conducted using twenty four Zaraibi goats (32.33+0.2Kg LBW and aged 3-4 years) at late pregnancy (one month before parturition). Animals were assigned into three similar groups (8 animals each) using the randomized complete block design. They were fed as groups on a basal ration, where concentrate feed mixture (CFM) was 50% of requirements according NRC (2007); while berseem as a roughage was offered at libitum.The tested rations were formulated from concentrate feed mixture (CFM) that partially substituted by 0, 15 and 30% of FWOC for CFM1, CFM2 and CFM3, respectively, along with berseem as a roughage portion to formulate the experimental rations R1 (Control), R2 and R3 as tested one. Results showed that nutrient digestibility coefficients and feeding values were improved with the higher level of FWOC (30%) in ration, than R2 and R1 (control). NH3-N values and TVF'A concentrations in the in rumen liquor were increase with increasing the level of FWOC up to 30% (R3) in ration. The vice versa trend was found among dietary treatment respecting pH values in rumen liquor. Actual milk yields were significant higher with R3 (1269.1g/d.) than control ration (R1 1047.6 and R2 1130.0 g, respectively). Concerning milk composition, R2 rations significant increased fat percentage compared with R3 ration and control one, while insignificant differ was observed with milk protein percentage among treatments, the highest value in R3. Improvement respecting milk TS was observed with FWOC rations compared with control ration with insignificant differences. No significant differences among experimental rations regarding all offspring performance measurements. At the end of the experimental period, plasma total protein was affected significantly (P<0.05) by the experimental rations with the highest value (7.75g/dl) was occurred with R3 and the lowest one (6.85g/dl) was with R1. Economic efficiency was improved by feeding ration that contained30% FWOC (R3) in comparison with R1. This study concluded that considerably to use mixture of food waste and olive cake up to 30% level could be recommended for formulation the rations of lactating Zaraibigoats. It was concluded that use 30% of mixture food waste and olive cake was more effective in lactating goats. It can pronounced enhance feed intake, digestibility, feeding values, milk production, feed efficiency, some blood parameters and economic efficiency evaluation of lactating goats.
