Twenty-four Nagavali ram lambs (average body weight 6-9 kg and 3-6 m age) were divided into four groups and assigned to four feeding regimens: (T1 to T4). The diets contained varying percentages of Guar meal viz., 50% (T2), 75% (T3) and 100% (T4). The effects of these diets on growth performance, were evaluated using a completely randomized design. The inclusion of Guar meal significantly (P < 0.05) improved total body weight gain and average daily gains in the T2, T3 and T4 groups along with non-significant(P > 0.05) improvement in dry mater intake in guar meal fed sheep. The observed dry matter intake of different treatments was 0.40 to 0.43 kg. Gross nutrients and cell wall digestibility parameters were not affected (P > 0.05). However, crude protein (CP) digestibility improved significantly (P < 0.05) with guar meal inclusion up to 75% (T3), after which a slight decline was noted at the 100% replacement level (T4). The invested cost per kg gain of body weight were $1.76, $1.69, $1.62 and $1.66 at T1 (0%), T2 (50%), T3 (75%) and T4 (100%) substitution levels, respectively, in line with FCR trends, demonstrating that T3 has the better results with comparatively low cost per kg gain. The study concludes that substituting soybean meal with 75% (T3) guar meal would enhance growth performance and aid in developing cost-effective rations.</p>","PeriodicalId":23329,"journal":{"name":"Tropical animal health and production","volume":"57 8","pages":"430"},"PeriodicalIF":1.7,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145239752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this, 22 male goats with 21.35 ± 0.57 kg mean body weight were distributed randomly into four groups. Goats were fed three incremental levels of trace minerals (TM) selenium (Se), zinc (Zn), copper (Cu) and manganese (Mn) and designated as TM1 (0.211 ppm Se, 41.33 ppm Zn, 8.82 ppm Cu and 36.13 ppm Mn), TM2 (0.511 ppm Se, 61.33 ppm Zn, 18.82 ppm Cu and 56.13 ppm Mn), and TM3 (0.811 ppm Se, 81.33 ppm Zn, 28.82 ppm Cu and 76.13 ppm Mn). Two environmental conditions were thermoneutral [TN; 67.75 Temperature Humidity Index (THI)] and heat stress (HS; 85.47 THI), and the exposure period was 40 days. Four experimental groups were TN-TM1, HS-TM1, HS-TM2, and HS-TM3. The TN-TM1 group showed a higher intake of all nutrients (P < 0.05), and HS-TM3 group had comparable crude protein and concentrate mixture intake to the TN-TM1 group. Digestibility of dry matter and organic matter was lower (P < 0.05) in HS-TM1 group, while ether extract digestibility was higher in HS-TM3 group compared with other groups. Total digestible nutrients content of the diet improved (P < 0.05) in HS-TM3 group and digestible organic matter and nitrogen and phosphorus absorption were greater (P < 0.05) in HS-TM3 and TN-TM1 groups, compared to other groups. The Cu balance was lesser (P ≤ 0.001) in HS-TM1 group and Mn balance showed improvement (P < 0.01) in HS-TM3 group compared to other groups. The Se balance was higher (P < 0.05) in HS-TM2 and HS-TM3 groups. The weekly body weight was similar, while weekly dry matter intake and average daily gain were higher (P ≤ 0.001) in TN-TM1 compared to HS groups. Thus, feeding higher levels of 0.811 ppm Se, 81.33 ppm Zn, 28.82 ppm Cu, and 76.13 ppm Mn under HS conditions resulted in increased nutrient digestibility, N absorption, and balance of trace minerals and had a subtle favorable impact on the growth performance of goats.</p>","PeriodicalId":23329,"journal":{"name":"Tropical animal health and production","volume":"57 8","pages":"431"},"PeriodicalIF":1.7,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145239792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the effects of genotype on growth performance, carcass traits, meat quality, and haemato-biochemical indices in three Nigerian indigenous chicken (NIC) varieties: Normal Feathered Chicken (NFC), Frizzle Feathered Chicken (FFC), and Naked Neck Chicken (NNC), and a commercial broiler breed (Arbor Acre Chicken, AAC). A total of 140 day-old chickens, with 35 birds per genotype, were reared for 8 weeks under controlled conditions. Growth performance traits, including body weight, body length, and other morphometric parameters, were measured, with AAC exhibiting the highest growth. Carcass traits followed similar patterns, with AAC showing superior slaughter weight, carcass weight, and carcass yield. Among the NICs, the FFC had higher feed efficiency and superior meat quality traits, including water-holding capacity and lower thawing loss. The AAC breed had higher fat and cholesterol content compared to NICs, while the crude protein content was highest in the NICs. Haemato-biochemical analysis revealed higher white blood cell counts and globulin levels in the NIC varieties, particularly FFC, indicating potential advantages in immune function. The results suggest that, while AAC excels in growth and carcass traits, the NIC varieties, especially FFC, may serve as valuable resources for breeding programmes focused on meat quality and disease resistance. This highlights the importance of genotype-specific breeding strategies for improving poultry production in Nigeria.</p>","PeriodicalId":23329,"journal":{"name":"Tropical animal health and production","volume":"57 8","pages":"422"},"PeriodicalIF":1.7,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145213625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
