“…Laying hens and broiler chickens given access to pasture may meet various nutrient needs through foraging [7,59]. It was reported that laying hens having access to grass resulted in a 20% reduction in feed consumption and increased egg production compared with hens raised under conventional conditions [59,60].…”

“…It was reported that laying hens having access to grass resulted in a 20% reduction in feed consumption and increased egg production compared with hens raised under conventional conditions [59,60]. Moreover, hens reared on alfalfa or clover need significantly less feed protein than confined hens [7]. In particular, alfalfa forage can supply carotene, vitamins and other nutrients, especially high amount of protein up to 19% as dry matter basis [61,62].…”

“…Similarly, poultry nutritionists have found that forages consumption is inversely tied to protein levels, since a higher protein content in the diet can result in a lower amount of plant matter consumed on pasture [63]. Further, poultry are able to utilize most of amino acids consuming forages, resulting in a significant level of methionine and lysine digested (88% and 79%, respectively) [7,59]. On the other hand, forages are low in energy, but these plants can contribute to the overall energy requirements of poultry.…”

“…Forages and forage meals could be valuable alternative sources of protein for commercial poultry where they are easily available and not expensive [7,8]. Moreover, forage utilization as local feed resource is important to facilitate the transition to 100% organic feed supply for organic poultry meat and egg producers [9].…”

Abstract:The present review discusses the existing research findings on the nutritional impact of forages in poultry diet and the significance of forages in sustainable poultry production systems. The nutritional composition and antinutritional factors of the main forages and the pros and cons of feeding forage on poultry meat and egg quality under free-range and organic production systems are also discussed. This review highlights the importance of forages and forage meals in poultry ration, considering that these feedstuffs may have greater value to the success of local poultry production in many regions of the world due to their potential of production.

“…The effect of the housing system on the final bodyweight was widely studied by many authors, most of whom suggest that free-range chickens obtain a lower bodyweight compared with chickens housed indoors (Castelini et al, 2002;Filho et al, 2003;Buchanan et al, 2007). However, it seems that the main factor influencing broiler's bodyweight is genotype, independently of the used production system (Castelini et al, 2008;Sirri et al, 2010).…”

The aim of the study was comparison of the results of rearing broilers kept under intensive and semi-intensive systems, fed with complete feeds with an addition of various proportions of wheat grain. The study was carried out on 100 broilers, HUBBARD -FLEX, of both sexes. The birds were reared up to 42 days of age in an intensive system (group I), as well as in a semi-intensive system (group II). In the 5th week of rearing, in the nutrition of group II, 30% of complete feed was replaced with wheat grain, increasing its proportion in the dose up to 50% in the last week of rearing. System of keeping broilers did not affect significantly their bodyweight at the end of rearing, as well as their meat yield and muscle content in carcasses. Chicken fed with complete feeds, kept under an intensive system were distinguished by higher fattiness expressed as an abdominal fat weight, as well as by lower average intake of feed mixtures per individual broiler.
