“…They confirmed the hypothesis of that higher N retention and nutrient utilization with proteinsupplemented feed to better conversion of rumen ammonia into microbial protein [29]. The correlation between plant extract supplementation and microbial activity legitimized the addition of fresh materials to the diet [30]. According to their ability to digest dry matter feed, Padjadjaran sheep (Ovisaries var.…”

Feeding management is a very important factor that makes sure fulfil quality and quantity for livestock nutrient sufficiency that affects the success rate in livestock farming. The excellent macro nutrient needs determination is an absolute thing to achieve the optimal growth which represented by digestibility and average daily gain. Feed formulation that considering the material selection, availability, and the price of feed materials could gave sustainable livestock feed management. The study was carried out to evaluate the effect of macronutrients needs on digestibility and average daily gain of sheep. Twenty Padjadjaran sheep (Ovisaries var. Padjadjaran, Family Bovidae), which resulted from crossbreeding between South-African Capstaad, Merino, and local, were chosen as tested animals. These white sheep were placed separately in individual metabolism cages. All animals were 8-10 months of age and their body weights ranged between 15-33 kg. The animals were divided into 5 groups and each group was treated with different dietary feeds (4 times replication) that contained dry material, crude protein, crude fiber, crude fat, and nitrogen-free extract (NFE). The parameters measured were dry matter intake (DMI), dry matter digestibility (DMD), organic matter digestibility (OMD) and average daily gain (ADG). The treatments showed no significant effect on DMI, DMD, and OMD, whereas an increase of ADG (113.33-169.17 g/animal/day) was observed on all animals. One of R2-treated animal showed an increase of 276.67 g/day.

“…The indoor sheep production system based on pelleted complete feed provides us with more opportunities than the grazing system, as it allows better manipulation of rumen fermentation, as well as increased feed efficiency and animal growth performance. A wide range of feed additives has been studied and applied for rumen fermentation manipulation in sheep production [3,4,5,6]. In addition to directly providing nutrients, such as rumen-protected lysine, the supplementation of microbial additives and antibiotics has been the major nutritional approach to altering rumen function and animal performance [7,8].…”

Simple SummaryPrevious works showed that supplementation of lysophospholipid as a feed additive improves animal growth and milk yield in beef and dairy cattle production. However, its effects on fattening lambs have not been reported before. In this study, we fed fattening lambs a diet with no or 0.5 g lysophospholipid in a kilogram of diet. We found that lysophospholipid did not or slightly improved the growth of fattening lambs. Feed digestibility, ruminal fermentation parameters and rumen bacterial community were altered, which may be associated with decreased fiber digestion. However, lipase concentration in serum was decreased, which might enhance fat deposition in muscle and thus may increase meat quality. Effects of lysophospholipid on sheep observed in this study are different from those on cattle, which warrants further study.AbstractFive experiments were conducted to examine effects of lysophospholipids (LPL) on live weight gain, nutrient digestibility, ruminal fermentation parameters, serum biochemical parameters and rumen bacterial community profile in fattening lambs. Two dietary treatments (pelleted complete feed supplemented without (control diet; CON) or with 0.05% LPL on dry matter basis) were tested in these experiments. Feed and water were provided ad libitum to lambs. The results showed that average daily gain (ADG) tended to increase or was not affected by LPL supplementation. Compared with CON, the supplementation of LPL resulted in an increase in dry matter, crude protein and organic matter digestibilities, and a decrease in neutral detergent fiber and acid detergent fiber digestibilities. Ruminal pH values did not change with LPL supplementation, but the concentrations of ammonia and total short chain fatty acids (SCFAs) were increased. The molar proportion of major individual SCFAs and the ratio of acetate to propionate were not affected by LPL supplementation. While the activity of lipase was decreased with LPL supplementation, all other serum biochemical parameters did not change. Rumen bacterial community was altered by LPL supplementation with the relative abundance of fibrolytic bacteria in the total bacterial population, such as Prevotella, decreased. In conclusion, LPL supplementation can alter feed digestion, but may not result in consistent positive responses in animal growth performance.

“…Dosage also represents a relevant issue; Guo et al (2012) [9] highlighted that the dietary addition of licorice extract in sheep had different effects on rumen fermentation in relation to different levels of licorice supplement and that when more than 4.5% licorice extract was added to the fermentation substrate, both ruminal gas and volatile FA (VFA) production were reduced. A decrease of VFA and acetate and an increase of the levels of propionate and butyrate were observed in Karakul sheep fed with 4.5% of licorice extract [36].…”

The aim of this study was to evaluate the effect of dietary licorice root supplementation on chemical and nutritional characteristics of cow milk and Stracciata cheese. Licorice did not influence milk and Stracciata fat content but induced modifications in fatty acid profile. Both in milk and Stracciata, a decrease in saturated fatty acids was detected and in cheeses an increase of monounsaturated and polyunsaturated fatty acids was observed. Stracciata obtained from the experimental group showed an improved oxidative stability after six days of ripening, a finding partly justifiable by the well-known richness of antioxidant compounds in the licorice root. The volatile profile of Stracciata was also affected by dietary licorice intake, with an increase in esters and a reduction of aldehydes and ketones. These results suggest a positive role of licorice in modifying chemical and physical properties of cow cheeses, reducing lipid oxidation and inducing changes in color and flavor with a presumable improvement in consumer acceptability.
