“…The lack of GP effects on broilers feed intake, weight OPEN ACCESS gain and feed conversion ratio observed in this study is in agreement with previous observations that indicated that herbs, plant extracts, essential oil and/or the main components of the essential oil that did not affect body weight gain, feed intake or feed efficiency in broilers [6,10,[16][17][18][19][20][21][22]. Lewis et al (2003) [7] showed that addition of plant extracts to broilers' diet has some effects on performance and microbial activity of intestinal tract but, none of them were significant.…”

This experiment was conducted to investigate the effect of feeding garlic powder (GP) on the performance, digestibility, digestive organs, carcass cuts and lipid profile of broilers. A total of 270 day-old Cobb-500 chicks were used in the experiment. Birds were partitioned into three experimental groups of 90 birds in each. Each treatment was composed of 6 replicates with 15 birds in each. The control group was fed with a commercial starter and finisher diet. The second and third groups were supplemented with GP at the rate of 0.2% and 0.4% respectively. In the last week of experiment, 18 birds from each experimental group (3 birds per replicate) were used in a metabolic trial. At the time of termination of the experiment, the same number of birds were killed for digestive organs and carcass components measurements. Blood samples from 3 birds per replicate were collected on 3 rd , 5 th and 6 th week post feeding from wing vein for blood lipid profile determination. Total cholesterol (COL), triglycerides (TG), high density lipoprotein (HDL), low density lipoprotein (LDL) levels were determined. Results of this study showed that GP had no significant effects on broilers weight gain, feed intake (FI), feed conversion ratio (FCR), carcass cuts, visceral organs. However, GP decreased (P < 0.05) COL, TG, LDL and increased HDL levels compared to control birds. The dry matter (DM), crude protein (CP) and ether extract (EE) digestibility were improved by feeding GP. It can be concluded that GP could provide positive advantages in broilers performance.

“…Improvement of broilers performance and carcass merits can be achieved by supplementation of diets with GP [6][7][8][9]. It was reported that feeding GP at levels of 1.5, 3 and 4.5% had no effect on birds performance [10], but caused a significant reduction in birds serum and liver cholesterol.…”

“…These findings concur with the data of Demir et al (2005), who indicated that the supplementation of dietary thyme powder (1 g kg −1 ) for 42 days numerically increased plasma cholesterol and triglyceride levels compared to the control. Osman et al (2010) reported that feeding dietary basil leaf powder for 42 days did not significantly influence the plasma cholesterol and triglyceride level in broilers.…”

Abstract. The effects of a probiotic (protexin), a medicinal plant (basil essential oil) and an antibiotic growth promoter (avilamycin) as broiler feed additives on performance, carcass characteristics and some blood parameters of broilers were studied. A total of 600 Arian broilers were divided into six treatments, with four replicates of 25 birds. Treatments were a plant essential oil in three levels (200, 400 and 600 ppm), the probiotic (150 ppm), the antibiotic (150 ppm) and a control group with no additives. Birds in different treatments received the same diets during the experimental period. Growth performance, blood biochemical parameters and carcass traits were measured. There were no effects of dietary treatment on body weight gain, feed intake and feed conversion ratio of the broilers. Internal organ weights and carcass characteristics were not influenced by treatments; however, 200 ppm basil essential oil supplementation decreased abdominal fat (P < 0.05). Biochemical parameters including serum low-density lipoprotein (LDL), high-density lipoprotein (HDL) and total cholesterol were not statistically influenced. However, addition of 400 ppm basil essential oil into diet increased serum triglyceride as compared to the control (P < 0.05). Results of this experiment demonstrated that the herbal natural feed additives such as basil may be used as alternatives to an antibiotic growth promoter without any adverse effects on broiler production.

“…There has been a lot of research on the potential benefits of herbs and spices in farm animal diets as a way to promote health and production, particularly after the banning of feed antibiotic growth promoters in Europe (Stammati et al 1999;Langhout 2000;Demir et al 2003;Greathead 2003;McIntosh et al 2003). Essential oils and/or oleoresins of garlic and capsicum, cinnamic aldehyde, carvacrol and pipperine (main active compound of black pepper) among others, have been used for their food flavor enhancing properties.…”

Can. J. Anim. Sci. 88: 535Á558. The evolution of the chemical senses has resulted in a sensory apparatus for high taste and smell acuity in mammals and birds to ensure self-nourishment. Such peripheral chemosensory systems function as a code to unfold the nutritional value of feedstuffs. Food ingestion simultaneously evokes odor, taste and thermo-mechanical (somatosensing) sensations. Olfaction represents the capacity to identify feed volatiles that are predominantly derived from essential nutrients in plants.Comparative biology of olfaction shows that primates and chickens have a smaller olfactory epithelium and fewer olfactory receptor (OR) genes than non-primate mammals studied to date including farm and companion animals, such as the pig, the cow, the dog, the cat and the horse. A significant proportion of the total OR genes in mammals and birds have lost their functionality (pseudogenes) in a process that seems to reflect a decrease in the animal's reliance on the sense of smell, particularly in humans and cows. The taste system allows animals to recognize a diverse repertoire of nutrient (sugars, amino acids, salts, acids and fats) or toxic related chemical entities that provide valuable information about the quality of food. Taste senses non-volatile molecules in the oral cavity through taste receptors (TR). The TR are expressed in the sensory cells forming the taste buds of the tongue's papillae. Taste cells are linked to a network of solitary chemosensory cells diffused through many non-taste tissues involved in metabolic homeostasis. The number of functional taste receptor genes (TASR) in humans is equivalent to that in other mammals and superior to that in chickens. The TASR family 1 (TAS1R coding for umami and sweet TR) is conserved, in number and type, across the species evaluated, with the exception of the sweet receptor in chicken and feline species. The TASR family 2 (TAS2R coding for bitter TR) shows a strong adaptive capacity to dietary sources and digestive physiology across vertebrates. Pseudogenization (loss of gene functionality) in the TAS2R family seems to be a frequent strategy. The implications of oronasal nutrient sensing related to comparative animal feeding strategies and behaviors such as neophobia, feed refusal and hedonic preferences are discussed. Feed palatability and appetence might be one of the main driving forces in short-term feed consumption. Finally, practical applications relevant to animal production are outlined.Key words: Nutrient sensing, taste, olfaction, somatosensing, feed intake, farm, companion animals Roura, E., Humphrey, B., Tedo´, G. et Ipharraguerre, I. 2008.
