“…Lupin is rich in nutrients such as containing all nine necessary amino acids, as well as other minerals [12]. In two recent studies in our laboratory, we concluded that the use of sweet lupin in feeding lactating ewes [10] and growing lambs [11] had a positive effect on profitability. This is due to their cheap prices, compared with the conventional feedstuffs.…”

“…The results are in good agreement with previous studies, in which results showed a reduction of 22% in the diet cost by replacing barley grains and soybean meal partially with LUP at 200 g/kg in the diet of lactating Awassi ewes [10] or 15 and 27% when barley grains and soybean meal is replaced with LUP at 125 and 250 g/kg, respectively, in diets of growing Awassi lambs. It is possible to reduce and stabilize the fluctuations of the diets in the cost of feeding grain and other feed sources by using LUP as an alternative [11]. Using this kind of legumes is potentially high in feeding livestock due to their cheap price and high nutrient content.…”

“…The main objective of using alternative feeds is to introduce a feed ingredient that reduces the cost of diets without affecting the performance and characteristics of carcasses. Sweet lupin (Lupinus angustifolius) is one of these options [10][11][12]. Lupin is an important legume in human nutrition.…”

“…Lupin is an important legume in human nutrition. However, when they are graded, there are large quantities that are not suitable for human consumption, with broken ones and small sizes [11]. Including them in animal feed is an appropriate step to reduce the burden of expensive feed costs.…”

“…According to its chemical composition, lupin is found to be a great source of protein and energy in the diet of ruminants. [10,11,13,14]. Lupin is rich in nutrients such as containing all nine necessary amino acids, as well as other minerals [12].…”

A study was conducted to examine how lupin grains (LUPs) feeding affected nutritional intake, digestibility, growth, and carcass characteristics in kids. A total of 24 growing black kids (initial body weight (BW) = 16.4 ± 0.49 kg) were allocated to one of three diets at random. Lupin was included in the diet at a rate of 0 (control; CON), 100 (LUP100), or 200 g/kg (LUP200) of total dry matter (DM). The trial lasted for 91 days divided into 7 and 84 days to be used for adaptation and data collection, respectively. Feed intake was evaluated daily throughout the study. At the commencement and the end of the study, each kid’s body weight was measured to determine its average daily gain (ADG). On day 70, 5 kids were chosen at random from each group to investigate nutrient in vivo digestibility and N balance. At the end of the study, all of the kids were slaughtered to examine carcass features. Nutrient intakes (neutral detergent fiber, acid detergent fiber, and ether extract) were higher (p ≤ 0.01) in LUP-containing diets than in the CON diet. The average daily gain was greater (p ≤ 0.03) in diets containing lupin grains than in the CON diet. Cost of gain ($US/kg growth) was lower (p = 0.004) in kids fed diets containing lupin than the CON diet. Dry matter and CP digestibility rates were greater (p ≤ 0.03) in lupin diets. Retained N was higher (p = 0.04) in lupin-containing diets than in the CON diet. Cold carcass weight was higher (p < 0.05) for kids consuming the LUP100 diet than the CON diet. In lupin diets, carcass cut weights were higher (p < 0.05). Results of the current study indicate that feeding black kids diets containing lupin grains at 100 or 200 g/kg DM basis is cost effective and would increase profitability.
