“…As a result, the lignin content of the crop residues in the study areas was close to 100 g/kg, which restricts the amount of DM that livestock may consume and livestock production. Therefore, it is essential to provide livestock with protein feed and treat crop residues with urea to boost the feeding value of low-quality crop residues, because crop residues can be treated with urea or efficient microorganisms to produce a product with higher nutritional value, especially when the untreated product has a very low nutritional value [ 36 , 37 ].…”

Livestock is important and plentiful in Ethiopia, but its potential is not being used to its full extent due to limited supply and inconsistent feed supply. This has a negative impact on livestock productivity in the tropics, where crop residues are used as livestock feed. The analysis of the nutritional content of feed and the measurement of feed production are crucial for maintaining the optimal balance of annual livestock feed and improving livestock production. However, no research has been conducted on the nutritional composition of the crop residues in the East Gojjam zone. Therefore, this study was conducted to analyze the nutritional content of crop residues in the three agroecologies in Ethiopia’s East Gojjam zone. Ash, dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber (ADF), and acid detergent lignin (ADL) were analyzed in the feed samples. According to the findings, the overall mean content of DM, ash, OM, CP, NDF, ADF, and ADL was 92.3, 5.2, 87.1, 4.1, 71, 56.6, and 9.6%, respectively. The faba bean has the highest CP (6.2%), followed by barley straws (5.5%), vetch haulms (5.5%), Eragrostis tef (3.7%), wheat straws (3.2%), and maize stover (2.9%). In general, all crop residues contain CP content below the critical CP level required even for livestock maintenance. The highest NDF was found in barley straw (75.1%), which was followed by wheat straw (72.0%), Eragrostis tef straw (70.2%), vetch haulms (69.3%), maize stover (67.4%), and faba bean haulms (67.2%). All types of crop residues were classified as low-quality feed because they contained more than 65% NDF, which could affect feed intake and livestock production. Therefore, crop residues must be improved using mechanical, biological, and chemical methods in order to increase livestock production in the study areas by increasing feed consumption.

“…Ruminant diets worldwide are dominated by locally grown forages that are either consumed by animals on pasture or fed as silage or hay when pasture is limited or unavailable due to adverse weather conditions (Wilkinson and Lee, 2018). However, the chemical composition of fibrous feeds (e.g., pastures, crop residues) is influenced by seasonality and is characterized by high volume, low energy content and especially small amount of proteins (Aruwayo, 2018;Tadele and Amha, 2015). Due to the high proportion of crude fibre, the digestibility of these feeds is considerably low.…”

Unique stomach physiology allows ruminants to utilise any form of dietary nitrogen (N) as a protein source. Ruminant N requirements can be divided into N requirements for microbial fermentation and host requirements for amino acids.Ruminant diets often contain non-protein nitrogen (NPN) compounds, a group of components that are not proteins but can be converted to proteins by rumen microbes. Therefore, NPN compounds in ruminant diets serve as alternative sources of ammoniacal nitrogen (NH 3 -N), which is necessary for the synthesis of microbial protein (MCP) in the rumen.MCP is an important component of metabolizable protein for ruminants and, under certain production conditions, may be the only amino acid source for synthesis of tissues and products. In this manner, ruminants utilise NPN compounds without having enzymes for their degradation. The use of NPN compounds in ruminant nutrition allows for an increase in feed consumption and utilisation, as well as the substitution of protein supplements, which in turn leads to more costeffective production. However, abrupt supplementation or excessive consumption of NPN could negatively affect MCP synthesis, feed digestion, and animal production. On the other hand, it may lead to animal poisoning and the release of large amounts of N into the environment. Knowledge of N metabolism in the rumen, as well as optimization of its utilisation, sets the conditions for the presumed beneficial effects of NPN compounds in ruminant diets, without adverse effects on animal health and the environment. Therefore, the aim of this study was to summarize the recent literature data on the metabolism and utilisation of NPN compounds in ruminants.

“…However, as the season terminates, these succulent forages become scarce and animals are left at the mercy of dry, fibrous, less palatable, less digestible, and nutritionally-deficient crop residues (straws and stover). Fermentable energy and protein deficiencies in crop residues coupled with their low digestibility impair intake, ruminal functions, and general productivity of animals (Aruwayo et al, 2018). Feed alone accounts for 60 -80% of the total cost of livestock production (Wang et al, 2022).…”

A 90-days feeding trial was conducted to evaluate the effect of replacing fertilizer grade urea with cattle urine in sorghum stover silage on the performance and haematological indices of Balami rams. Five diets were formulated. Diet 1 (control) contained sorghum stover ensiled with fertilizer grade urea (FGU) while diets 2, 3, 4 and 5 had 25, 50, 75 and 100% levels of cattle urine as replacement for FGU. Twenty (20) rams of the Balami breed were allotted to the five diets in replicates of four in a completely randomized design. Data on daily feed intake, weight gain and haematological indices were collected Results showed no significant influence of cattle urine on daily feed intake. However, Daily weight gain was significantly (P<0.05) higher on T5 (128.11 g) and T4 (124.08 g) which were the same, than on other diets which also did not differ (101.67 – 103.65 g). Similarly, Rams fed T5 (34.53 kg) had higher (P<0.05) final weight than those on other diets which were the same (30.30 – 31.93 kg). Feed conversion ratio was significantly (P<0.05) better on T5 (5.74) and T4 (5.88) compared to T1 (7.19), T2 (7.13) and T3 (7.06) which were poorer. All haematological indices did not significantly differ among diets. It was therefore concluded that cattle urine can completely replace fertilizer grade urea as silage additive in sorghum stover and as non-protein nitrogen source in balami rams diets.
